Description:FIELD OF THE INVENTION

[0001] The present invention relates to an autonomous pipeline monitoring and hazard mitigation device that provide continuous and autonomous monitoring of gas pipelines for detecting external defects, gas leaks, and abnormal conditions, thus enabling prompt alerts and responses to potential hazards.

BACKGROUND OF THE INVENTION

[0002] The increasing global reliance on pipelines for transporting critical resources such as natural gas, oil, and other industrial fluids has significantly heightened the need for effective and reliable pipeline monitoring and maintenance. Pipelines, often spanning large geographic areas and traversing harsh environments, are prone to wear and tear, external damage, and degradation over time. As a result, the risk of pipeline failures, including gas leaks, cracks, and insulation damage, poses serious environmental, economic, and safety concerns.

[0003] Traditional pipeline inspection and maintenance methods often rely on manual checks or periodic surveillance, which is time-consuming, expensive, and do not effectively identify developing issues in real-time. Moreover, human intervention in hazardous environments, particularly in remote or dangerous areas, introduces additional risks and inefficiencies. These shortcomings necessitate the development of means that continuously monitor the health of pipelines, detect potential issues early, and take preventive or corrective actions to avoid catastrophic failures.

[0004] US20060225507A1 discloses about an invention that has a process and apparatus for sensing possible leaks in a pipeline. The pipeline is monitored continuously by acoustic monitoring means, and acoustic events indicating a possible leak are noted. The pipeline is also equipped with temperature monitoring means, and is monitored for temperature either continuously, periodically or on demand. A leak is deemed probable at any location where there is an acoustic event indicating a possible leak, and at approximately the same time, a temperature difference greater than a pre-chosen amount between that location and adjacent locations.

[0005] US4796466A discloses about a system for monitoring pipelines through which fluids, be they gases or liquids flow using conventional readily available monitoring equipment, that determines the probability of a leak as opposed to the actuality of a leak using a moving average of statistical information gained from a plurality of monitoring stations that monitor either pressure or flow.

[0006] Conventionally, many devices are available for monitoring pipelines and hazards. However, the cited invention often lacks the capability for immediate, automated intervention, such as sealing leaks or neutralizing hazardous gas emissions. The conventional methods typically provide detection and monitoring in isolation without integrated means to address the identified risks in real-time. As a result, they rely on manual interventions, which lead to delayed responses and missed opportunities for early hazard mitigation.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that requires to be capable of not only continuously monitoring pipeline conditions but also actively responding to potential hazards in real time. The developed device should be capable of autonomously detecting defects, gas leaks, and environmental factors that pose risks to pipeline integrity and take immediate corrective actions, such as sealing cracks, neutralizing leaks, and controlling environmental conditions, thereby reducing the need for manual intervention.

OBJECTS OF THE INVENTION

[0008] The principal object of the present invention is to overcome the disadvantages of the prior art.

[0009] An object of the present invention is to develop a device that is capable of enabling continuous and autonomous monitoring of overhead gas pipelines for identifying defects, damages, and hazards, thus reducing the need for manual inspection and enhancing pipeline safety.

[0010] Another object of the present invention is to develop a device that is capable of detecting potential gas leaks promptly for facilitating early intervention and preventing hazardous situations.

[0011] Another object of the present invention is to develop a device that is capable of providing real-time alerts to personnel in case of abnormal conditions, thereby enabling swift action and reducing response time to potential pipeline issues.

[0012] Another object of the present invention is to develop a device that is capable of mitigating the effects of gas leaks for ensuring minimal environmental impact and enhancing safety.

[0013] Another object of the present invention is to develop a device that is capable of enabling proactive maintenance and assessment of pipeline condition by analyzing the sound and material properties of the pipeline, thus providing valuable data for estimating its remaining lifespan and planning necessary maintenance or replacements.

[0014] Another object of the present invention is to develop a device that is capable of monitoring and regulating the ambient temperature around the pipeline to predict and address potential risks arising from external environmental factors, thus ensuring optimal operating conditions for the pipeline.

[0015] Yet another object of the present invention is to develop a device that is capable of enhancing safety during pipeline operations by projecting a virtual boundary in view of alerting nearby personnel of potential hazards and ensuring safe distances are maintained.

[0016] The foregoing and other objects, features, and advantages of the present invention will become readily apparent upon further review of the following detailed description of the preferred embodiment as illustrated in the accompanying drawings.

SUMMARY OF THE INVENTION

[0017] The present invention relates to an autonomous pipeline monitoring and hazard mitigation device that automatically address detected gas leaks by sealing cracks, containing leaks, and neutralizing harmful gases, while also assessing the pipeline's structural integrity and lifespan, thus supporting proactive maintenance and ensuring pipeline safety.

[0018] According to an embodiment of the present invention, an autonomous pipeline monitoring and hazard mitigation device, comprises of a body equipped with multiple motorized wheels that enable the body to navigate along the overhead pipeline. At the top of this body is a rotatable artificial intelligence-based imaging unit, responsible for capturing high-resolution images and videos of the external surface of the pipeline. These images and videos are analyzed by an inbuilt microcontroller for any visible defects, wear, or damage, an ultrasonic sensor is installed on the body to inspect the external surface of the pipeline, specifically checking for defects or damage to the pipeline’s outer insulation. The collected data is processed by the inbuilt microcontroller, which assesses the condition of the pipeline. If any abnormal conditions are detected, the microcontroller triggers alerts that are sent to a concerned personnel’s computing unit for immediate action.

[0019] For gas leak detection, an MQ7 sensor integrated with an electrochemical gas sensor positioned on the body to detect specific gases in the surrounding environment. When a gas leak is identified, the microcontroller activates a motorized slider and collapsible rod to close windows of the enclosure housing the pipeline, thereby preventing the leakage from escaping into the industrial space. A telescopic bar and motorized clamping unit, controlled via a ball-and-socket joint, to open or close a pipeline valve at the specific section of the pipeline where the gas leak is detected. When a gas leak is detected, the microcontroller also triggers an electronic nozzle that disperses a calcium hydroxide solution stored in a chamber. The nozzle is activated to sprinkle the solution in the affected area, with the motion of the body’s wheels ensuring even coverage. The calcium hydroxide neutralizes the gas for mitigating the potential hazard. To address physical cracks or defects in the pipeline, a telescopic link mounted on the slider with a V-shaped member, which holds a pair of C-shaped clamps. Inside these clamps are motorized sliding units that facilitate a motorized roller, which holds a fire-resistant adhesive plastic sheet. The microcontroller controls the roller to unroll the adhesive sheet across the leakage area, temporarily sealing the crack. The clamps are equipped with electromagnets that ensure the sheet stays in place during the sealing process. A motorized clipper is attached to the clamps via a telescopic pole and is controlled by the microcontroller to pick up the adhesive sheet and place it accurately on the crack. A robotic arm with a motorized cutting blade is also included for allowing the blade to cut the sheet to the required length for precise application.

[0020] To assess the internal conditions of the pipeline and estimate its remaining lifespan, a robotic link integrated with a hammering unit that strikes the exterior of the pipeline, and an acoustic sensor installed on the body analyzes the sounds produced. This information is used to identify the type of material of the pipeline and assess its internal conditions. The results are sent to the computing unit for enabling proactive maintenance and replacement planning. A series of thermal sensors installed on the body to monitor the ambient temperature surrounding the pipeline. The microcontroller correlates this data with the internal temperature of the pipeline to predict potential risks arising from external environmental factors. If any irregularities or temperature fluctuations are detected, alerts are sent to the computing unit in view of prompting the concerned personnel to take appropriate action. For safety and operational purposes, a holographic projection unit is installed on the front side of the body. This unit projects a virtual boundary around the pipeline upon detecting potential hazards. This virtual boundary helps ensure that personnel stay within safe zones and avoid hazardous areas, thereby enhancing safety during pipeline inspection and maintenance and a battery is associated with the device for supplying power to electrical and electronically operated components associated with the device.

[0021] While the invention has been described and shown with particular reference to the preferred embodiment, it will be apparent that variations might be possible that would fall within the scope of the present invention.

[0026] The present invention relates to an autonomous pipeline monitoring and hazard mitigation device that monitor and regulate environmental factors like ambient temperature and project safety boundaries within gas leak region for enhancing operational safety, minimizing external risks, and providing real-time alerts to personnel for timely intervention.

[0027] Referring to Figure 1, an isometric view of an autonomous pipeline monitoring and hazard mitigation device is illustrated, comprising a body 101 configured with multiple motorized wheels 102 adapted to navigate along overhead gas pipelines, a rotatable artificial intelligence-based imaging unit 103 is installed on a top portion of the body 101, a flap 104 is attached to a motorized slider 105 provided on top perimeter of the body 101 via a collapsible rod 106, a telescopic bar 107 is attached to slider 105, top end of the bar 107 is connected to a motorized clamping unit 108, an electronic nozzle 109 attached with a chamber 110 stored with calcium hydroxide solution and configured at the body 101, a telescopic link 111 mounted on the slider 105 and integrated with a V-shaped member 112 installed with a pair of C-shaped clamps 113, both clamps 113 are equipped with a motorized sliding unit 114 that facilitates movement of a motorized roller 115, which holds a fire-resistant adhesive plastic sheet 116, a motorized clipper 117 attached with the clamp 113 via a telescopic pole 118, a motorized cutting blade 119 is attached to body 101 via a robotic arm 120, a robotic link 121 attached to the top portion integrated with a hammering unit 122 and a holographic projection unit 123 is installed at front side of the body 101.

[0028] The device disclosed herein includes a body 101 that is installed with multiple motorized wheels 102 to enable smooth and efficient navigation along the length of an overhead gas pipeline. These wheels 102 are equipped with motors that allow for independent or coordinated movement for ensuring the device travel along the pipeline's surface, regardless of the terrain or incline. The wheels’ motorized nature provides the flexibility to adjust speed, direction, and position, enabling precise maneuverability. This is particularly important in pipeline inspections, where the device move with accuracy over long distances while ensuring stability on the pipeline’s surface.

[0029] On top of the body 101, an artificial intelligence (AI)-based imaging unit 103 is mounted for monitoring the pipeline’s external surface. The imaging unit 103 is rotatable, allowing it to capture a 360-degree view of the pipeline's condition. The rotation enables the imaging unit 103 to adjust its angle and orientation autonomously for ensuring comprehensive coverage without requiring manual adjustments. The AI-based imaging unit 103 is designed to process visual data in real-time, using machine learning protocols to detect and identify issues such as cracks, corrosion, dents, and any other anomalies on the pipeline’s external surface. The imaging unit 103 capture both high-resolution images and videos for providing a detailed visual record of the pipeline’s state.

[0030] The processor carries out a sequence of image processing
operations including pre-processing, feature extraction, and classification by
utilizing artificial intelligence and machine learning protocols. The image
captured by the imaging unit is real-time images and videos of the pipeline.
The artificial intelligence based imaging unit transmits the captured image signal in the form of digital bits to the microcontroller. The microcontroller upon receiving the image signals compares the received image signal with the pre-fed data stored in a database and constantly determines detailed visual record of the pipeline’s state.

[0031] The imaging unit 103 is not limited to merely capturing images and videos but also processes and analyzes the visual data to identify potential threats or damage. For example, the imaging unit 103 distinguish between normal surface conditions and those that indicate possible pipeline deterioration, such as corrosion or physical damage caused by external impacts. The imaging unit 103 also flag areas that require closer inspection or intervention, which enhances the efficiency and effectiveness of the monitoring process. Furthermore, the integration of the AI-based imaging unit 103 allows the device to learn and adapt over time, improving its ability to detect subtle changes in the pipeline’s condition that are not easily visible to the human eye. The images and video footage captured by the imaging unit 103 are typically stored or transmitted to a central computing unit, where they are further analyzed or reviewed by personnel for providing critical insights into the pipeline's health and helping to plan future maintenance or repairs.

[0032] The microcontroller activates an inbuilt communication module for establishing a wireless connection between the microcontroller and computing unit that is inbuilt with a user-interface and accessed by the user for enabling the user to give input commands for removal of weed from the field. The user interacts with the interface through a touch screen, keyboard, or other input methods available on the computing unit. The computing unit mentioned herein includes, but not limited to smartphone, laptop, tablet. The communication module mentioned herein includes, but not limited to Wi-Fi (Wireless Fidelity) module, Bluetooth module, GSM (Global System for Mobile Communication) module.

[0033] An ultrasonic sensor is installed on the body 101 that work in conjunction with the AI-based imaging unit 103. The ultrasonic sensor is designed to inspect the external surface of the pipeline for potential defects, such as cracks, corrosion, or damage to the outer insulation. Ultrasonic sensors are widely used for non-destructive testing because as these sensors detect structural flaws without needing to physically alter or damage the pipeline. The sensor emits high-frequency sound waves, which penetrate the pipeline’s surface and reflect back when they encounter variations in material density or surface irregularities. These sound waves are then measured to determine the presence of any defects beneath the surface. By analyzing the reflected waves, the sensor detects variations such as voids, cracks, or corrosion that are not visible to the human eye or detectable through traditional visual inspections.

[0034] The ultrasonic sensor is synchronized with the AI-based imaging unit 103 to provide a comprehensive and complementary analysis of the pipeline’s condition. While the imaging unit 103 captures visual data and identifies visible defects on the pipeline’s external surface, the ultrasonic sensor focuses on the structural integrity of the material beneath the surface. The data from both the imaging unit 103 and the ultrasonic sensor are processed simultaneously by an inbuilt microcontroller, which acts as the central processing unit for the entire device. This microcontroller integrates the data streams from both the ultrasonic sensor and the imaging unit 103, thus combining visual and acoustic information to provide a more thorough understanding of the pipeline's health.

[0035] The microcontroller analyzes the data from both sources, cross-referencing the ultrasonic readings with the visual evidence obtained by the imaging unit 103. For example, if the imaging unit 103 detects a visible crack or corrosion on the pipeline's surface, the ultrasonic sensor assesses whether there is any internal damage or degradation beneath that area. If the ultrasonic sensor detects abnormalities like thinning of the pipeline material or internal cracks, the sensor alerts the microcontroller to the potential seriousness of the issue. This approach allows for a more accurate determination of the pipeline's condition, as it accounts for both external and internal factors, providing a more complete picture of the pipeline's overall structural integrity.

[0036] When the microcontroller processes the data and determines that the pipeline is in an abnormal condition such as a significant crack, potential gas leak, or severe corrosion, it triggers corresponding alerts. These alerts are sent in real-time to a concerned personnel’s computing unit, notifying them of the detected issue. The alerts include specific details, such as the location of the defect, the severity of the damage, and whether the problem is isolated to a particular section of the pipeline or part of a larger issue. This ensures that the relevant personnel are promptly informed and take necessary action, whether it’s conducting a closer inspection, initiating repairs, or implementing preventive measures to avoid a potential failure.

[0037] The microcontroller also ensures that the device operates autonomously by continuously processing the data from both the imaging and ultrasonic sensors. This allows the device to monitor the pipeline's condition over time, automatically detecting any emerging issues without requiring human intervention.

[0038] An MQ7 sensor integrated with an electrochemical gas sensor, both of which aids in detecting potential gas leaks in the surrounding environment. The MQ7 sensor is specifically designed to detect carbon monoxide, a gas that is indicative of hazardous conditions, while the electrochemical gas sensor is capable of detecting a broader range of gases that leak from the pipeline, such as methane or other hydrocarbons commonly associated with gas pipelines. These sensors are placed on the body 101 to ensure accurate monitoring of the surrounding air. As the device navigates along the pipeline, the sensors continuously sample the air to detect any changes in gas concentration, particularly focusing on any leaks that pose a danger to both the pipeline infrastructure and the surrounding industrial environment. The integration of these sensors enables the device to not only identify gas leaks but also distinguish between different types of gases, providing more specific data about the leak’s nature and potentially allowing for more targeted responses.

[0039] Once a gas leak is detected by either the MQ7 sensor or the electrochemical gas sensor, the information is sent to the inbuilt microcontroller, which processes the sensor data in real time. Upon confirming the presence of a gas leak, the microcontroller triggers an immediate response designed to contain the leak and prevent the gas from spreading. A motorized slider 105, located along the top perimeter of the body 101 and installed with a flap 104, which is connected via a collapsible rod 106. The primary function of this flap 104 and rod 106 is to act as a barrier that close windows or openings in the enclosure housing the pipeline. The motorized slider 105 moves the flap 104 into position, and when activated, the flap 104 is deployed to effectively seal the windows, preventing any leaking gas from escaping into the interior of the industrial configuration. This is especially important in environments where even small amounts of leaked gas lead to hazardous conditions, such as in confined spaces or sensitive industrial facilities.

[0040] When a gas leak is detected at a specific point along the pipeline, the microcontroller coordinates the movement of the motorized slider 105 and collapsible rod 106, ensuring that the flap 104 closes securely and effectively seals the windows of the enclosure. This response helps to mitigate the spread of dangerous gases within the facility for preventing contamination of the internal environment and reducing the risk of explosion or other serious consequences associated with uncontained gas leaks.

[0041] In addition to the flap 104 and rod 106 assembly, the body 101 is equipped with a telescopic bar 107 attached to the slider 105. The telescopic bar 107 extends and contracts as needed to respond to various situations where different pipeline configurations or leak locations require adjustment. The telescopic bar 107 mentioned above basically consist of multiple cylindrical sections with one section sliding inside the other. The sections are basically made of materials that may include but are not limited to metals and lightweight alloys. The telescopic bar 107 as mentioned herein are powered by a pneumatic unit that utilizes compressed air to extend and retract the bar 107. The process begins with an air compressor which compresses atmospheric air to a higher pressure. The air cylinder of the pneumatic unit contains a piston that moves back and forth within the cylinder. The cylinder is connected to one end of the telescopic rods. The piston is attached to the telescopically operated bar 107 and its movement is controlled by the flow of compressed air. To extend the telescopic bar 107 the piston activates the air valve to allow compressed air to flow into the chamber behind the piston. As the pressure increases in the chamber, the piston pushes the
telescopic bar 107 to the desired length.

[0042] At the top end of the telescopic bar 107 is a motorized clamping unit 108, which is connected via a fourth motorized ball-and-socket joint. The ball-and-socket joint allows for precise and controlled movement of the clamping unit 108 for enabling the device to accurately manipulate the pipeline valve when a gas leak is detected. When the microcontroller identifies a gas leak at a specific location, it actuates the motorized clamping unit 108, which open or close the pipeline valve depending on the severity of the leak and the immediate need for isolation of the affected section of the pipeline.

[0043] For example, in the case of a detected leak, the motorized clamping unit 108 precisely close a valve for effectively isolating the damaged section of the pipeline and preventing the gas from escaping further. This is important for managing the flow of gas in response to leaks, as it minimizes the spread of the hazardous substance and helps contain the issue until more permanent repairs are made.

[0044] An electronic nozzle 109 connected to a chamber 110 mounted on the body 101 stored with a calcium hydroxide solution. The nozzle 109 aids in neutralizing any hazardous gases detected during the operation. Calcium hydroxide, commonly known as slaked lime, is a highly effective substance for neutralizing acidic gases like carbon dioxide, sulfur dioxide, or other potentially harmful gases that are released from the pipeline due to leaks. When gas leaks are detected, particularly in industrial settings where these gases pose serious health or safety risks, the nozzle 109 provides an automated and efficient means to mitigate those risks.

[0045] Upon the detection of gas leak by the sensors, the microcontroller takes immediate action. The microcontroller processes the sensor data and determines whether the leak requires neutralization. If a leak is confirmed and deemed significant enough to warrant an immediate response, the microcontroller activates the nozzle 109, which then releases the calcium hydroxide solution in a controlled and precise manner. The nozzle 109 directs the solution accurately over the affected area for ensuring that the neutralizing agent is applied directly to the location of the gas leak. This targeted release helps to maximize the effectiveness of the solution for reducing waste and ensuring that the neutralizing effect is concentrated where it is most needed.

[0046] When the gas leak is detected, the microcontroller not only activates the nozzle 109 but also adjusts the movement of the wheels 102 to ensure the device moves smoothly over the leak’s location. This coordinated action ensures that the calcium hydroxide solution is evenly distributed across the affected area, covering a larger surface and ensuring maximum coverage. As the device travels along the pipeline, the nozzle 109 continuously sprinkle the solution over the gas leak or its vicinity for creating a buffer zone where the harmful gases are neutralized before they spread further.

[0047] The distribution of calcium hydroxide is particularly crucial in industrial environments, where even small leaks escalate into major safety concerns if left unchecked. By applying the solution directly to the affected area, the device prevents the harmful gas from spreading into the environment, thus reducing the risk of contamination and potential harm to the workers or surrounding infrastructure. The microcontroller is configured to adjust the flow rate of the calcium hydroxide solution based on the severity of the leak for ensuring that a sufficient amount of neutralizing agent is used when a large or persistent leak is detected, and reducing the application when a smaller, less critical leak is identified.

[0048] The chamber 110 that stores the calcium hydroxide solution holds an adequate amount of the neutralizing agent for ensuring that the device operate autonomously for extended periods without needing frequent refills. The chamber 110 is sealed to prevent any leakage or evaporation of the solution during transportation or when the device is idle, thus ensuring that the solution remains ready for use when required.

[0049] A telescopic link 111 mounted on the motorized slider 105, which is equipped with an integrated V-shaped member 112 at its end-effector. This configuration is designed to facilitate the precise application of a fire-resistant adhesive plastic sheet 116 over a crack or damaged section of the pipeline in view of temporarily sealing the area to prevent further leakage of gas or other harmful substances. The V-shaped member 112 that is positioned at the end of the telescopic link 111, provides both stability and flexibility. This allows the device to approach and engage the pipeline's surface with precision, in view of positioning the adhesive sheet 116 exactly where it is needed, even in challenging pipeline configurations or difficult-to-reach areas.

[0050] The V-shaped member 112 holds a pair of C-shaped clamps 113 that are mounted using a first motorized ball-and-socket joint. The ball-and-socket joint allows for fine, precise adjustments in the orientation of the clamps 113 for ensuring that the clamps 113 are positioned optimally around the damaged section of the pipeline. This flexibility enables the clamps 113 to conform to the shape of the pipeline for ensuring that the adhesive sheet 116 is applied effectively without gaps or misalignments. The use of a motorized ball-and-socket joint adds an additional layer of precision in view of ensuring that the clamping and sealing process is fully controlled by the microcontroller, thus minimizing human intervention and reducing the risk of errors.

[0051] Inside each of the C-shaped clamps 113, a motorized sliding unit 114 is installed that facilitates the movement of a motorized roller 115. The roller 115 holds the fire-resistant adhesive plastic sheet 116 for sealing the crack or damaged area on the pipeline. The adhesive sheet 116 is specifically designed to withstand high temperatures and pressure, making it ideal for temporary pipeline repairs, particularly in emergency situations where more permanent solutions are not immediately feasible. The motorized sliding unit 114 allows the roller 115 to move the adhesive sheet 116 across the crack or damage on the pipeline’s surface. When a leak is detected and a crack or damage is identified, the microcontroller activates the motorized roller 115 to unroll the sheet 116 and cover the affected area. This ensures that the sealing process is automated and precise, which is essential for maintaining the integrity of the pipeline during the repair procedure.

[0052] The adhesive sheet 116 is fire-resistant for ensuring that the sheet 116 withstand the hazardous conditions that often accompany gas leaks or high-pressure situations in industrial pipelines. The motorized roller 115 carefully unrolls the adhesive sheet 116, placing it in the correct alignment with the crack or damaged area. This precise application ensures that the sheet 116 fully covers the damaged section, effectively sealing the crack and preventing further leakage of gas or other substances. The fire-resistant properties of the adhesive plastic sheet 116 also ensure that the sheet 116 endure the harsh conditions around gas pipeline without degrading or losing its adhesive qualities.

[0053] To ensure the adhesive sheet 116 stays securely in place once applied, each of the C-shaped clamps 113 is equipped with electromagnets at the edges. These electromagnets aids in holding the adhesive sheet 116 in place on the pipeline surface during the sealing process. Once the adhesive sheet 116 is aligned with the crack or damaged area, the electromagnets are activated, engaging with the pipeline surface and securing the sheet 116 in position. This electromagnetic engagement ensures that the adhesive sheet 116 does not shift or fall off during the sealing process, even if external forces such as wind, vibration, or pipe movement occur. The electromagnets create a strong bond between the sheet 116 and the pipeline for preventing misalignment or displacement of the adhesive during the temporary seal application.

[0054] The application of the adhesive plastic sheet 116 is vital for maintaining the integrity of the pipeline until more permanent repairs are made. The entire process is controlled by the microcontroller, which not only coordinates the movement of the motorized roller 115 but also manages the activation of the electromagnets to secure the sheet 116 in place. By deploying the fire-resistant adhesive sheet 116 over the crack or damaged area, the device creates a temporary yet effective barrier, thus reducing the risk of further leakage and providing a crucial window for repairing the pipeline.

[0055] A motorized clipper 117 is attached to the clamp 113 via a telescopic pole 118, which is connected to a second motorized ball-and-socket joint. This ball-and-socket joint provides a high degree of flexibility and precision in controlling the clipper’s movement. The telescopic pole 118 allows for adjustments in the clipper's position, extending or retracting as needed to reach different sections of the pipeline. The motorized ball-and-socket joint enables fine control over the clipper's angle and orientation, ensuring that the clipper 117 approach the crack or damaged section of the pipeline from the correct position and apply the adhesive sheet 116 with high accuracy.

[0056] When the gas leak is detected, the microcontroller activates the motorized clipper 117 to pick up the free-ends of adhesive plastic sheet 116 from the motorized roller 115 inside the C-shaped clamps 113. The clipper’s operation is coordinated with the overall sealing process to ensure that the adhesive sheet 116 is applied exactly where it is needed. The clipper 117 grips the adhesive sheet 116 securely and lift it from the roller 115 without damaging or misaligning the sheet 116. Once the clipper 117 has securely grasped the sheet 116, it carefully positions the adhesive over the crack or damaged area of the pipeline. This ensures that the adhesive sheet 116 is accurately placed on the pipeline surface, covering the leak completely and forming a reliable temporary seal to prevent further gas leakage.

[0057] In addition to the clipper 117, a motorized cutting blade 119 is mounted on a robotic arm 120 attached to the body 101 to precisely cut the adhesive plastic sheet 116 to the required length for each specific leak. The microcontroller controls the cutting blade’s operation for ensuring that the sheet 116 is cut with high precision, so the adhesive material is neither too long nor too short, providing the exact coverage needed for effective sealing. The robotic arm 120 allows the blade 119 to be precisely positioned and operated to cut the sheet 116 to the desired length. This is particularly important for ensuring that the adhesive sheet 116 fits perfectly over the damaged area, thus covering the crack without overlapping excessively or leaving gaps.

[0058] A robotic link 121 that is attached to the top portion of the body 101 via a third motorized ball-and-socket joint to assess the structural integrity of the pipeline by using a hammering unit 122 integrated into free end of the link 121. The hammering unit 122 is designed to strike the exterior surface of the pipeline for creating controlled impacts that are analyzed to gain valuable insights about the condition of the pipeline. This aids in identifying potential weaknesses in the pipeline and allowing for proactive maintenance or replacement before these issues result in failures or leaks.

[0059] The third motorized ball-and-socket joint, which connects the robotic link 121 to the body 101 offers a high degree of flexibility and precision. The ball-and-socket joint allows for full rotational movement and fine adjustments in the hammering unit’s orientation, thus enabling it to target specific areas of the pipeline. This ensures that the hammering unit 122 is positioned accurately to strike various points on the pipeline, even those in difficult-to-reach or confined locations. The ability to precisely control the movement of the robotic link 121 and the hammering unit 122 is critical for performing a thorough and effective assessment of the pipeline's external surface, especially when dealing with long stretches of pipeline that have varying conditions along their length.

[0060] When the hammering unit 122 strikes the pipeline, it generates an acoustic signal that travels through the pipe's material. To analyze these signals, the body 101 is equipped with an acoustic sensor that is installed on the body 101. This sensor is highly sensitive and capable of detecting and analyzing the sound produced when the hammering unit 122 impacts the exterior of the pipe. The acoustic signal that results from the hammering is a valuable source of information as the way sound travels through a material reveal important details about the material's properties, such as its composition, thickness, and structural integrity. Different materials and conditions produce distinct acoustic patterns when struck, so by analyzing these patterns, the microcontroller determine what type of material the pipe is made from.

[0061] In addition to identifying the material type, the acoustic analysis is also used to assess the internal condition of the pipeline. The characteristics of the sound wave that travels through the pipeline depend not only on the external surface but also on the internal state of the pipe. For example, pipes with internal corrosion, wear, or buildup produce different acoustic responses compared to a pipe in good condition. By carefully analyzing the acoustic data, the microcontroller detects signs of internal damage, including cracks, corrosion, or other structural issues that are not immediately visible on the outside of the pipeline. This internal assessment is critical for understanding the overall health of the pipeline and help identify issues that otherwise go unnoticed until they lead to more severe problems, such as leaks or complete failure.

[0062] The acoustic sensor’s data is processed by the microcontroller, which evaluates the sound patterns and compares them to established protocols or databases of known acoustic signatures for various pipe materials and conditions. Based on this analysis, the microcontroller estimates the remaining lifespan of the pipeline. For example, if the sensor detects signs of significant corrosion or internal degradation, the microcontroller predicts a shortened remaining lifespan for that section of the pipeline. Conversely, if the pipeline is in good condition, the device estimate a longer operational life before maintenance or replacement is required.

[0063] Once the analysis is complete, the results are sent to a computing unit, where they are compiled into a report that provides detailed insights into the pipeline's current state. This report includes information on the material type, any detected internal issues, and an estimate of the remaining lifespan of the pipeline. The ability to remotely access this data allows for proactive maintenance planning and timely decision-making. Pipeline operators use this information to schedule maintenance activities, prioritize sections of the pipeline that require repairs, and determine when sections need to be replaced, all based on the real-time condition of the pipeline. By utilizing acoustic signals to assess both the internal and external health of the pipeline, the device enables a predictive approach to pipeline management, helping to avoid emergency repairs and ensuring the safety and reliability of the pipeline network.

[0064] A plurality of thermal sensors is installed on the body 101 to continuously monitor the ambient temperature surrounding the pipeline. These thermal sensors possess the ability to assess the environmental conditions that potentially affect the safety and operational integrity of the pipeline. Ambient temperature plays a significant role in the overall health of a pipeline, especially when considering the materials, the pipeline is made of, the substances being transported, and the external environmental conditions that fluctuate, such as temperature extremes or rapid changes in weather.

[0065] The thermal sensors provide real-time data on the temperature around the pipeline, capturing any significant shifts in the surrounding environment. The microcontroller processes the data from these thermal sensors in conjunction with the internal temperature of the pipeline, which is typically monitored by separate internal sensors or is inferred based on other factors. The microcontroller compares and correlates the external ambient temperature with the pipeline’s internal temperature.

[0066] By continuously monitoring both external and internal temperatures, the microcontroller predict and identify potential risks that arise due to environmental factors. For example, if a sharp drop in external temperature occurs in a region where the pipeline is carrying gas or liquid at a relatively higher temperature, the microcontroller predicts that there is a risk of the pipeline materials contracting too quickly, which result in cracks, stress fractures, or even rupture in some cases. Similarly, if the external temperature becomes excessively high, it causes the pipeline material to expand beyond its designed tolerance, again putting the pipeline at risk for structural damage. In either case, the microcontroller is pre-fed to identify such risk scenarios and calculate whether the environmental conditions pose a threat to the pipeline’s safety.

[0067] In the event that the microcontroller detects that the external temperature is deviating beyond safe operational limits, the microcontroller triggers an alert to the concerned personnel through connected computing unit. This alert takes various forms, including visual and auditory signals on the interface or direct notifications via an integrated means that connects the device to the control center or personnel’s computing unit. By sending out timely alerts, the device ensures that the personnel responsible for pipeline management are promptly informed of any abnormal environmental changes that could potentially jeopardize the pipeline’s integrity.

[0068] These alerts are not only reactive; they are also predictive in nature. Based on historical data and real-time monitoring of the pipeline and external conditions, the device predict potential problems before they escalate into actual failures. For example, if the external temperature is consistently increasing, the device predicts a higher likelihood of thermal expansion-related issues within the pipeline, prompting the need for immediate inspection, maintenance, or temperature regulation measures. Conversely, if a significant drop in temperature is detected, the device alerts the personnel to inspect insulation or adjust the pipeline’s operation to prevent damage from cold-related contraction.

[0069] A holographic projection unit 123 installed on the front side of the body 101 for enhancing safety and operational efficiency during pipeline monitoring and hazard mitigation. The primary function of the holographic projection unit 123 is to create a virtual boundary in the vicinity of the pipeline when a potential hazard is detected. This virtual boundary acts as a safety marker, alerting operators, personnel, and others in the vicinity of potential dangers associated with the pipeline, ensuring that individuals and equipment maintain a safe distance from hazardous areas.

[0070] The holographic projection unit 123 generate three-dimensional projections that are displayed in the real world, directly in the vicinity of the pipeline. The projection unit 123 is designed to project virtual barriers, safety zones, or hazard warning indicators without the need for physical barriers or signs. This is particularly useful in environments where installing permanent physical markers, such as in remote locations, overhead pipeline sections, or areas where the terrain or surrounding infrastructure makes traditional barriers difficult to implement. The holographic projections are designed to be clearly visible and recognizable, even in complex or challenging operational environments, providing an effective means of communicating safety information in real time.

[0071] Moreover, a battery is associated with the device to supply power to electrically powered components which are employed herein. The battery is comprised of a pair of electrodes known as a cathode and an anode. A voltage is generated between the anode and cathode via oxidation/reduction and thus produces the electrical energy to provide to the device.

[0072] The present invention works best in the following manner, where the body 101, equipped with motorized wheels 102, moving along the overhead gas pipeline. The AI-based imaging unit 103, mounted on top, captures continuous images and videos of the pipeline’s external surface, allowing for real-time monitoring of the pipeline’s condition. Simultaneously, the ultrasonic sensor works in synchronization with the imaging unit 103 to detect any potential defects or damage to the pipeline’s outer insulation. The microcontroller processes the data from both sensors, analyzing the pipeline's health, and if any abnormal conditions are detected, it triggers alerts on personnel's computing unit to initiate corrective actions. If the gas leak is detected through the integrated MQ7 sensor and electrochemical gas sensor, the microcontroller activates motorized slider 105 and collapsible rod 106 to close windows around the pipeline’s enclosure, preventing leakage into the industrial interior. The telescopic bar 107 and motorized clamping unit 108 to open or close the pipeline valve at the affected section, limiting gas exposure. If the leak persists or is detected, the electronic nozzle 109 sprays calcium hydroxide solution over the affected area, with the actuation of the wheels 102 ensuring even distribution.

[0073] In continuation, the telescopic link 111 with C-shaped clamps 113 and motorized roller 115 allows for the precise application of fire-resistant adhesive plastic sheet 116 to temporarily seal the crack. If necessary, the motorized clipper 117 and cutting blade 119 are used to accurately place the sheet 116. The hammering unit 122, equipped with acoustic sensor, then strikes the exterior of the pipeline to analyze the sound and determine the material, internal conditions, and remaining lifespan of the pipeline. These diagnostics are sent to the computing unit for proactive maintenance planning. In conjunction with these actions, the microcontroller monitors the ambient temperature using thermal sensors, correlating the data with the pipeline’s internal temperature to predict risks due to environmental factors. Alerts are sent to the personnel to maintain safe operating conditions. Upon detecting any hazard, tow holographic projection unit 123 is activated to project virtual safety boundary around the pipeline for ensuring clear visual warning to personnel.
