Description:FIELD OF THE INVENTION

[0001] The present invention relates to a rainwater harvesting and filtration device for roof of vehicle that is developed for integration with vehicles to enable efficient collection, filtration, and management of rainwater, whether the vehicle is in motion or stationary, by performing automated adaptation, water quality monitoring, and customized water distribution, thereby enhancing water conservation practices for vehicle owners.

BACKGROUND OF THE INVENTION

[0002] Collecting rainwater from a vehicle's rooftop has been a practical idea for some time, but traditional methods were not efficient, especially when it came to filtration. People often use simple funnels or tanks to catch rain, but these systems didn’t offer any filtration. The collected water would easily become contaminated with debris like leaves, dirt, and dust, making it unsafe to use. Moreover, traditional setups required a lot of manual effort, like cleaning and adjusting the collection devices. These systems also lacked any way to filter the water, meaning that contaminants remained in the water, even after collection. The small storage capacity often led to water being wasted or poorly stored. The absence of proper filtration made these methods less reliable, especially for drinking or irrigation. In essence, older rainwater harvesting systems for vehicles were inefficient, unsanitary, and lacked the necessary features for effective and safe water use.

[0003] Conventionally, some vehicle owners used basic makeshift systems like funnels or simple containers placed on rooftops to catch rainwater during travel or while parked. These rudimentary methods were ineffective for large-scale collection and often lacked any filtration or storage. So, people also use motorized collection systems, as these systems involve retractable plates mounted on the rooftop that extend and retract to conform to the vehicle's shape, helping to collect rainwater effectively. These systems include integrated filtration units that remove debris and contaminants from the collected rainwater, often through multiple stages. While modern systems include advanced filtration units, these systems require regular maintenance. Filters, tanks, and pumps need to be cleaned and serviced regularly to prevent clogging, contamination, or system failure. This ongoing maintenance is costly and time-consuming for vehicle owners.

[0004] CN202519738U discloses about an invention that includes a rainwater collection system for an automobile. The system comprises a rainwater collection groove, a water storage tank and a main control unit, wherein the rainwater collection groove is connected with the water storage tank through a collection pipe. The system is characterized in that a purifier is arranged on the collection pipe; a conveying pump is arranged at the water outlet of the water storage tank; a water supply distribution control valve is arranged at the water outlet of the conveying pump and respectively connected with a cooling water tank and an automobile-mounted air conditioner humidifier; liquid level sensors are arranged in the water storage tank, the cooling water tank and the automobile-mounted air conditioner humidifier; and the liquid level sensors, the conveying pump and the water supply distribution control valve are electrically connected with the main control unit. The system has a simple structure, is low in power, can be integrated into automobile electronics, can be used as an independent sub-assembly and embedded into the automobile, and is high in practicability, water resources are recycled at low cost, and the aim of saving the resources is fulfilled.

Simple cleaning and wiping can be performed on a vehicle through collected rainwater during journey, thereby providing convenience to the majority of vehicle drivers. By popularizing and using the vehicle-mounted rainwater collecting and utilizing system, the problem of being lack of water when driving the vehicle can be effectively solved, and natural water resources can be simultaneously effectively utilized. The vehicle-mounted rainwater collecting and utilizing system has the advantages of simple structure, convenience in use, water conservation and environment friendliness.

[0006] Conventionally, many devices have been developed that are capable of collecting and filtering rainwater from the vehicle roof. However, these devices are incapable of ensuring that collected rainwater is tested for factors such as contaminants, pH levels, and clarity. Additionally, these existing devices also lack in providing different levels of filtration depending on the intended use of the water.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that is capable of continuously monitoring water quality, in view of ensuring that any collected rainwater is tested for factors such as contaminants, pH levels, and clarity, thus ensures that only safe and clean water is stored and ready for use. In addition, the developed device also allows users to customize the filtration process and manage collected water based on their specific needs, whether for personal consumption, irrigation, or other applications, thereby providing different levels of filtration depending on the intended use of the water.

DETAILED DESCRIPTION OF THE INVENTION

[0019] The following description includes the preferred best mode of one embodiment of the present invention. It will be clear from this description of the invention that the invention is not limited to these illustrated embodiments but that the invention also includes a variety of modifications and embodiments thereto. Therefore, the present description should be seen as illustrative and not limiting. While the invention is susceptible to various modifications and alternative constructions, it should be understood, that there is no intention to limit the invention to the specific form disclosed, but, on the contrary, the invention is to cover all modifications, alternative constructions, and equivalents falling within the spirit and scope of the invention as defined in the claims.

[0020] In any embodiment described herein, the open-ended terms "comprising," "comprises,” and the like (which are synonymous with "including," "having” and "characterized by") may be replaced by the respective partially closed phrases "consisting essentially of," consists essentially of," and the like or the respective closed phrases "consisting of," "consists of, the like.

[0021] As used herein, the singular forms “a,” “an,” and “the” designate both the singular and the plural, unless expressly stated to designate the singular only.

[0022] The present invention relates to a rainwater harvesting and filtration device for roof of vehicle that is capable of facilitating the efficient gathering of rainwater from the exterior of a vehicle, while optimizing the process irrespective of the vehicle's motion or stance, thereby guaranteeing that rainwater is captured and preserved for later use, even when the vehicle is in transit.

[0023] Referring to Figure 1 and 2 a perspective view of a rainwater harvesting and filtration device for roof of vehicle and an internal view of a chamber associated with the present invention is illustrated, respectively, comprising a plate 101 adapted to be mounted on rooftop of a four-wheeler vehicle, an artificial intelligence-based imaging unit 102 is installed on the plate 101, multiple suction units 103 provided on a bottom surface of the plate 101, plurality of telescopic rods 104 provided at each corner of the mounting plate 101, multiple spindles 105 are provided on lateral sides of the plate 101, a vertically linear ratchet assembly 106 is mounted at the plate 101, a gutter 107 provided with sides of the plate 101, a storage chamber 108 provided with the plate 101, an L-shaped link 201 mounted on an upper section of the chamber 108, the link 201 supporting a box 202 integrated with an electronic valve 203, the plate 101 is further installed with plural filtration containers 109, the plate 101 further comprises of extendable legs 110, wherein a 3-dimensional (3D) holographic projector 111 is mounted on the plate 101.

[0024] The device disclosed herein comprising a plate 101 configured for installation on the rooftop of a four-wheeler vehicle is provided. The plate may be rectangular, cuboidal, cubical, square or of any shapes. The plate 101 includes extendable leg 110 operable to deploy from a stowed position to contact the ground surface. Deployment of the legs 110 is actuated automatically in response to signals received from a motion sensor or upon identification of adverse weather conditions. The grounding of the plate 101 enhances structural stability and reduces displacement risk during environmental fluctuations or vehicular motion.

[0025] The motion sensor continuously monitors the vehicle’s physical state using accelerometric and gyroscopic data. Upon detecting abrupt movements, vibrations, or significant shifts in orientation, the sensor sends real-time signals to a microcontroller. The microcontroller interprets these signals as potential instability and triggers deployment of the extendable legs 110. The legs 110 then extend downward until firm contact with the ground is established. Once the motion ceases or conditions normalize, a retraction command is issued.

[0026] The legs 110 are pneumatically actuated, wherein the pneumatic arrangement of the legs 110 comprises of a cylinder incorporated with an air piston and the air compressor, wherein the compressor controls discharging of compressed air into the cylinder via air valves which further leads to the extension/retraction of the piston. The piston is attached to the telescopic legs 110, wherein the extension/retraction of the piston corresponds to the extension/retraction of the legs 110. The actuated compressor allows extension of the legs 110 for grounding the plate 101 in view of enhancing device stability.

[0027] The plate 101 is installed with an artificial intelligence-based imaging unit 102 which detect dimensions of rooftop of the vehicle. The imaging unit 102 disclosed herein comprises of an image capturing arrangement including a set of lenses that captures multiple images of the surroundings and the captured images are stored within memory of the imaging unit 102 in form of an optical data. The imaging unit 102 also comprises of the processor which processes the captured images.

[0028] This pre-processing involves tasks such as noise reduction, image stabilization, or color correction. The processed data is fed into AI protocols for analysis which utilizes machine learning techniques, such as deep learning neural networks, to extract meaningful information from the visual data which are processed by the microcontroller to detect dimensions of rooftop of the vehicle.

[0029] Synchronously, the microcontroller regulates the actuation of a motorized drawer arrangement integrated within the plate 101. The drawer arrangement consists of multiple plates that are overlapped to each other with a sliding unit, wherein upon actuation of the multiple plates and sliding unit by the microcontroller, the motor in the sliding unit starts rotating a wheel coupled via a shaft in clockwise/anticlockwise direction providing a movement to the slider in the drawer arrangement to extend/retract in order to modulate dimensions of the plate 101 to conform to the vehicle.

[0030] A plurality of suction units 103 (preferably 2 to 6 in numbers) is operatively positioned along the bottom surface of the mounting plate 101. The suction units 103 are configured to generate negative pressure zones upon activation, thereby facilitating secure attachment of the plate 101 to the rooftop surface of a four-wheeler vehicle.

[0031] Upon actuation the suction units 103 creating a vacuum seal between the bottom surface of the mounting plate 101 and the vehicle rooftop. An internal pump or actuator draws air out of the enclosed contact area, reducing pressure beneath each unit. This pressure differential generates strong downward force, anchoring the plate 101 firmly in place. The microcontroller continuously monitors pressure levels to maintain optimal suction. If detachment is needed, reverse airflow is triggered to neutralize the vacuum, releasing the plate 101. Each unit functions independently yet in coordination, enabling secure and adaptive attachment across varying roof contours and surface materials.

[0032] A plurality of telescopic rods 104 (preferably 2 to 6 in numbers) is operatively disposed at respective corners of the mounting plate 101, each rod 104 being structurally configured and works similarly as of legs 110 mentioned above. On actuation the rods 104 perform vertical extension and retraction in a linear direction. The distal ends of the rods 104 are mechanically linked to one another via a flexible coupling element, wherein the interconnection enables the collective formation of a conical support structure upon full extension.

[0033] A plurality of spindles 105 (preferably 2 to 6 in numbers) is mounted on the lateral sides of the plate 101, each spindle 105 being rotatably configured and wrapped with a waterproof cloth. Upon activation, each spindle 105 is operable to unroll the cloth in a controlled manner. The unrolled cloth extends outward to cover the conical structure formed by the telescopic rods 104, thereby establishing a protective surface over the framework.

[0034] Each motorized spindle 105 operates through an electric motor directly connected to the spindle 105 shaft. When a command is initiated, the motor supplies rotational motion to the spindle 105 in a forward direction. This rotation causes the waterproof cloth, which is wrapped around the spindle 105, to gradually unroll. As the spindle 105 continues rotating, the cloth extends and spreads over the conical structure. The motor maintains steady rotation until the cloth is fully deployed. To retract, the motor reverses direction, causing the spindle 105 to roll the cloth back into its original position. This bidirectional control enables repeated deployment and retraction as required.

[0035] A global positioning system (GPS) module is operatively integrated within the microcontroller and configured to determine and track the real-time geographic coordinates of the vehicle. The microcontroller is further configured to utilize an embedded internet communication module to access and retrieve live weather data corresponding to the vehicle's detected location. The integration of location tracking and environmental data enables automated regulation of the device operational parameters based on the geographic position and prevailing weather conditions encountered by the vehicle during transit or while stationary.

[0036] The GPS module receives signals transmitted from multiple satellites orbiting the Earth. These signals contain time and positional data which the module uses to calculate the precise geographic coordinates of the vehicle. Upon receiving at least four satellite signals, the module performs trilateration to determine latitude, longitude, altitude, and movement direction. This data is continuously updated and transmitted to the microcontroller. The microcontroller then uses these coordinates to perform location-based operations, including fetching region-specific weather data via the internet module.

[0037] Based on detected real-time weather conditions the microcontroller actuates a vertically linear ratchet assembly 106 which is mounted at the plate 101 and connected to the flexible coupling. Upon receiving a signal from the microcontroller based on detected weather conditions, the vertically linear ratchet assembly 106 is activated. The ratchet mechanism engages, causing a rotational motion to be transferred to a gear arrangement that is connected to a vertically aligned track. This motion converts rotational energy into linear displacement, raising the flexible coupling. As the coupling moves upward, it directly lifts the conical structure formed by the telescopic rods 104, which are attached to the coupling.

[0038] The upward movement continues until the structure reaches a predetermined height, where the ratchet locks into place, preventing any downward movement. The height is precisely controlled to ensure that the conical structure is at an optimal angle. As a result, the waterproof cloth, which is wrapped around the rods 104, becomes taut and forms a slanted plane. This slanted plane allows rainwater to flow effectively into a gutter 107 provided with lateral sides of the plate 101 for collection, ensuring proper rainwater redirection and drainage.

[0039] A vibrating unit is integrally embedded within the waterproof cloth, positioned to operate after rainfall. Upon receiving a signal from the microcontroller, the vibrating unit is activated, causing it to generate rapid oscillations. These vibrations are transmitted across the surface of the waterproof cloth, agitating the material and facilitating the movement of residual water that remains after rainfall. The oscillations work to break surface tension and force the water droplets to dislodge and slide off the cloth. The vibration continues for a predefined period, ensuring thorough removal of any remaining moisture. Once complete, the vibrating unit deactivates, leaving the cloth dry, clean, and free from accumulated water.

[0040] A plurality of motorized iris holes (preferably 2 to 6 in numbers) is distributed circumferentially along the bottom section of the gutter 107 to regulate the flow of rainwater. Each iris holes are designed to open and close in response to actuation signals, controlling the passage of rainwater into the storage chamber 108. Above each iris holes, a metal mesh filter is mounted, configured to intercept and filter solid debris such as leaves, branches, and particulate matter from the rainwater. This mesh ensures that only clean water enters a storage chamber 108, preventing clogging and maintaining the quality of the collected water.

[0041] The iris holes comprise of a ring and a blade with multiple protrusions. The ring is fabricated with multiple grooves. The ring is installed with the motor that is actuated by the microcontroller for rotating the ring with a specified speed to regulate the opening and closing of the holes in order to control the passage of rainwater and intercept solid debris.

[0042] An L-shaped link 201 is mounted on the upper section of the storage chamber 108, with the link 201 supporting a box 202 that is integrated with an electronic valve 203. The box 202 contains alum, which is released into the stored water upon activation of the electronic valve 203. The microcontroller controls the actuation of this valve 203. Upon actuation, the alum is dispensed into the water, where it interacts with impurities, facilitating the process of flocculation and sedimentation. This action accelerates the aggregation of suspended particles, causing them to settle at the bottom of the chamber 108. This process enhances water clarity and ensures the effective removal of contaminants.

[0043] The electronic valve 203 actuator, which is powered electrically, moves to open the valve 203. This action releases alum from the storage box 202 into the stored water. The valve 203 remains open for a predetermined duration, ensuring sufficient alum is dispensed to promote flocculation and sedimentation of water impurities. After the set release time, the valve 203 closes, stopping further alum flow. The valve 203 precise operation allows controlled and efficient release of alum, optimizing water purification processes.

[0044] A sensing module is integrated within the storage chamber 108 and comprises a pH sensor, a turbidity sensor, and a biosensor. The sensors are configured to monitor and assess various quality parameters of the stored water. The pH sensor determines the acidity or alkalinity level, the turbidity sensor evaluates the presence of suspended particles by measuring water clarity, and the biosensor detects biological contaminants. Data collected from these sensors is transmitted to the microcontroller, which processes the information to determine the suitability of the stored water for specific uses based on real-time quality assessments.

[0045] The pH sensor operates by immersing an electrode into the stored water. When activated, the electrode generates a voltage signal corresponding to the concentration of hydrogen ions present in the water. This signal is transmitted to the microcontroller, which calculates the pH value based on the detected voltage level. The pH value indicates whether the water is acidic, neutral, or alkaline. This real-time reading is used to assess the chemical balance of the water and determine its suitability for intended applications. The pH sensor operates continuously or at scheduled intervals to ensure accurate and updated quality monitoring of the stored water.

[0046] The turbidity sensor operates by emitting a beam of light into the stored water through an optical transmitter. A photodetector placed at an angle measures the amount of light scattered by particles suspended in the water. As the concentration of suspended solids increases, more light is scattered, and less reaches the detector. The sensor converts the detected light intensity into a turbidity value, which is sent to the microcontroller. This value indicates the clarity of the water and helps determine the presence of particulate matter.

[0047] The biosensor functions by using a biological recognition element placed in contact with the stored water. Upon exposure to biological contaminants such as bacteria or organic matter, the recognition element reacts and produces a measurable signal, often electrical or optical. This signal is processed by a transducer and sent to the microcontroller, which interprets the data to detect the type and level of biological contamination present. The biosensor operates in real time or scheduled intervals to assess microbial safety of the water.

[0048] A hose and pump unit are integrated within the chamber 108 to transfer collected water towards a plurality of filtration containers 109. Upon activation, the pump facilitates the movement of water from the chamber 108 through the hose and directs it into the appropriate filtration containers 109. This ensures that the water is effectively channelled into the designated containers 109 for purification. The pump unit operates in a controlled manner, ensuring that the flow of water is consistent and directed precisely toward the filtration containers 109, enhancing the overall efficiency of the filtration process.

[0049] Upon activation, the pump draws water from the chamber 108 using suction. The pump then generates pressure that forces the water through the hose. The water flows through the hose towards the filtration containers 109, where it is directed into the appropriate chamber 108 for further filtration. The pump’s operation ensures the steady flow of water, and its flow rate is adjusted as needed, ensuring a controlled, even distribution of water into the containers 109. The pump unit helps maintain optimal performance in water filtration containers 109.

[0050] Plurality of filtration containers 109, each configured to perform a distinct filtration function in accordance with specific user requirements. The filtration containers 109 include a drinking water container incorporating an activated carbon filter designed for the adsorption of chemical impurities to render the water suitable for consumption.

[0051] An irrigation container is also provided, comprising a screen filter configured to remove fine debris while allowing the passage of particulate-tolerant water appropriate for agricultural or landscaping applications. Additionally, a rainwater harvesting container is integrated, including a sand filtration member configured to eliminate residual sediments and direct the filtered water to a designated harvesting pit through a controlled outlet positioned on the container. The configuration of the filtration containers 109 allows the user to selectively utilize treated water based on intended application, thereby supporting multi-purpose water reuse and optimized resource management.

[0052] After water is collected in the storage chamber 108, it is directed toward the drinking water container containing the activated carbon filter. As the water flows through the porous carbon material under pressure, chemical impurities, odors, and volatile organic compounds are adsorbed onto the carbon surface. This process allows cleaner water to exit the filter. The filter functions until its adsorption limit is reached, after which its effectiveness diminishes and replacement is required.

[0053] Thereafter water intended for irrigation flows into the irrigation container comprising a screen filter. As water passes through the mesh, the screen physically obstructs fine debris and solid particles exceeding a predefined size. Filtered water continues through the outlet for particulate-tolerant applications. Over time, debris accumulation on the screen surface can reduce flow, necessitating either manual or automated cleaning to restore the filter’s intended functionality and maintain desired throughput.

[0054] Further for rainwater harvesting purposes, water is channelled into the container fitted with a sand filtration member. As water passes vertically through successive sand layers, residual sediments and suspended particles are captured within the granular media. Cleaned water exits from the base through a controlled outlet and is directed toward a designated harvesting pit.

[0055] The imaging unit 102 herein capture visual data of individuals within the device’s vicinity. In the event of detecting a suspected intruder, the unit utilizes facial recognition technique to analyze and identify facial features. Upon identification, the imaging unit 102 stores this facial recognition data securely. Subsequently, the captured data is transmitted via secure communication protocols to an authorized personnel’s computing unit. This transmission triggers an alert, which contains the visual evidence, enabling authorized personnel to review and take appropriate action as necessary.

[0056] The plate 101 is installed with a 3-dimensional (3D) holographic projector 111 which provide assistive visual information regarding the rainwater harvesting process. The holographic projector 111 disclosed herein, comprises of multiple lens. After getting the actuation command from the microcontroller, a light source integrated in the projector 111 emits various combination of lights toward the lens which is further portrayed to project visual information regarding the rainwater harvesting process, displaying real-time information about nearby harvesting pits experiencing water scarcity, thereby allowing the user to make informed decisions about distributing water.

[0057] In an embodiment of the present invention a level sensor is integrated within the storage chamber 108 to continuously monitor the water level. The level sensor operates by emitting ultrasonic waves to detect the water level within the chamber 108. When water rises to a particular height, the sensor’s signal changes in response to the presence of water, indicating the current level. The sensor then sends this data to the microcontroller. Once the water reaches the predefined threshold, the microcontroller sending a notification to the computing unit. This ensures that the water level is accurately monitored and that users are alerted in time to take appropriate action, preventing overflow.

[0058] Moreover, a battery is associated with the device for powering up electrical and electronically operated components associated with the device and supplying a voltage to the components. The battery used herein is preferably a Lithium-ion battery which is a rechargeable unit that demands power supply after getting drained. The battery stores the electric current derived from an external source in the form of chemical energy, which when required by the electronic component of the device, derives the required power from the battery for proper functioning of the device.

[0059] The present invention works in the best manner, where the plate 101 adapted to be mounted on rooftop of the four-wheeler vehicle. The plate 101 further comprises of extendable legs 110 capable of grounding the plate 101 based on motion of the vehicle as detected via the motion sensor or deteriorating weather conditions. The artificial intelligence-based imaging unit 102 detect dimensions of rooftop of the vehicle. Synchronously, the motorized drawer arrangement extend/retract to modulate dimensions of the plate 101 to conform to the vehicle. Multiple suction units 103 secure the plate 101 over the vehicle’s rooftop. Plurality of telescopic rods 104 provided at each corner of the mounting plate 101, each rod 104 the rods 104 is configured to vertically extend and retract and tip ends of the rods 104 are connected to each other via flexible coupling to collectively form the conical support structure. Multiple spindles 105 are each wrapped with the waterproof cloth. And the cloth, when unrolled covers the conical structure formed by the rods 104. Simultaneously, the global positioning system (GPS) module is configured to track location coordinates of the vehicle. And the microcontroller utilizes the onboard internet module to detect real-time weather conditions. Based on which the microcontroller regulates extensions of the cloth for collection of rainwater via vertically linear ratchet assembly 106. Thereafter the vibrating unit displace residual water post-rainfall, maintaining dryness and cleanliness of the cloth. The waterproof cloth forms the slanting plane for effective rainwater redirection into the gutter 107 provided with lateral sides of the plate 101.

[0060] In continuation, plurality of motorized iris holes controls the passage of rainwater. The metal mesh filter intercept solid debris including leaves, branches, and particulates from rainwater before the rainwater enters the storage chamber 108 which is provided with the plate 101. Afterwards the L-shaped link 201 is supporting the box 202 integrated with the electronic valve 203 that releasing alum into the stored water thereby accelerating flocculation and sedimentation of impurities to bottom layer of the storage chamber 108. Synchronously, the sensing module measures the acidity or alkalinity, density and presence of suspended solids, and biological contaminants in the water, to detect quality of water. The hose and pump unit directing collected water towards plural filtration containers 109 for filtration, each configured for the specific application, for allowing the user to use the treated water as per preferences. Further the imaging unit 102 also captures and store facial recognition data of the suspected intruder, and transmits the alert containing the visual evidence to authorized personnel’s computing unit. Furthermore, the 3-dimensional (3D) holographic projector 111 provides assistive visual information regarding the rainwater harvesting process, displaying real-time information about nearby harvesting pits experiencing water scarcity, allowing the user to make informed decisions about distributing water.
