The present invention relates to method to rescue child from borehole or small gap using retracted trigger rope pulley drive borewell machine.
Background of the Invention
In the current context, clean water scarcity is driving the construction of underground bore-wells to obtain water. And the number of bore-wells is growing by the day. In most cases, if there is no water available in the bore-well, the constructors leave it as is, which is why those life-threatening bore-wells exist. In other cases, children who are unaware of such bores, as well as children who play carelessly near such uncovered bore-wells, become victims. Narrow holes in the ground constructed by a drilling machine in order to gain access to the groundwater system are called as bore well/hole. Boreholes are usually narrow (typically 150 mm (6 inches) in diameter) and can be constructed quickly. Modern drilling machines uses compressed air to drive a rotating hammer that smashes up the rock. The air exhaust from the hammer tool blows the broken rock chips and water in the hole, up to the ground surface.
Researchers all over the world are working on developing a machine/setup to safely rescue trapped children from bore holes. US10765896B2, for example, describes the operation of a rescue device that includes a support assembly, a seating assembly, and a gripper assembly. The support assembly is made up of two holding arms that are designed to hold the victim. An extendable seat rod and a seat attached to one end of the extendable seat rod comprise the seating assembly. In order to facilitate positioning of the seat relative to the victim, the seat is designed to move relative to the extendable seat rod.
The clamping assembly includes a clamp that is designed to help the victim position relative to one or more of the support assembly and seating assembly. Because of the presence of subsystems such as a support system, a seating system, and a clamping system, this mechanism takes a long time to rescue. In US10857401B2, a mechanism for rescuing a victim trapped in a well was disclosed. The well rescue device includes a clamp assembly that is designed to support the victim's torso while moving the victim. Furthermore, the well rescue device includes a seat assembly that is designed to provide seating support to the victim. It will be difficult to operate the seat assembly system if the bore well hole is small.
According to the record released by the fire rescue team, the entire operation will take approximately 11 hours using the existing retraction procedure. The same issue was identified in the majority of the prior art (US20150306434A1). As a result, there is an urgent need for an improved bore well rescue device that can effectively rescue victims in a short period of time. The present invention overcomes these prior art problems and discloses the operation of a bore well rescue device that is available of the above said limitations.

Summary of the Invention
In light of the above-mentioned drawbacks in the prior art, the present invention aims to rescue victim from bore well/small hole effectively within a short time period.
The specific objective of the invention is to design retracted trigger rope pulley drive borewell machine to rescue with all life supporting systems for the trapped victim.
Another goal of the invention is to create a simple retracting mechanism that does not necessitate many complex sub - components and can operate even in small holes.

Detailed Description of the Invention
The light-weight device is proposed in our invention that can be easily transported from one location to another due to the possibility of trapped victims in different locations at different times. This device can overcome the disadvantages of parallel digging, such as increased time consumption, increased rescue personnel, and a very low chance of success in saving a child's life. With reference to the figure 1 the ‘using retracted trigger rope pulley drive mechanism is provided. The setup fabricated was a functional prototype; it is developed to evaluate the major systems of the mechanisms in real time. The setup was used to carry out 1. Supporting frame 2. Drive box 3. Tigger pull rope 4. pulley 5. Expandable base plates 6. Cylindrical wall 7. Rope winding mandrel 8. Supporting bracket 9. Vertical arm plate 10. an optical camera.
Rope, pulley, and an automated rope winding shaft make up the lifting elements. The rope is made of nylon, and the pulley is made of metal. As a lifting element, we could have used a chain and sprocket or a gear drive. The main issue with chain and sprocket drives, as well as gear drives, is that they are fixed drives. On the other hand, Rope is flexible enough to be used in both short and long depths because it can be wound around for lifting and releasing. Furthermore, rope is much lighter in weight and has a smaller cross section than other lifting elements, which is very beneficial in construction process where size and weight are both important considerations. The most basic requirement of life is oxygen and extraction of the child may take several hours during the rescue operation. If the child does not get enough oxygen in the bore-well, he may develop hyperthermia, and we may not be able to save his or her life. As a result, an oxygen supply unit is essential for providing adequate oxygen to the child. The oxygen cylinder, pressure gauge and hose are all included.
The opening and closing of the claws are controlled manually outside the borewell using a rotating drive motor that rotates clockwise and anticlockwise. The system is placed inside the borewell with the help of the wireless camera that comes with the device, the child's position can be seen on the monitor as soon as the device reaches him. With the help of a camera and a DC motor, the device will rotate based on the child's position. After grabbing the child's hand, the device has a gripper to hold it. Lowering a vertical rod with a plate at the end into the bore well with another mechanism. The child's live position is captured using a camera, and communication with the child is accomplished using a microphone and a working amplifier. The child is picked up in a suitable position, and the system is then pulled out of the borewell by the rope. When it reaches the child, use the push lever at the top of the rod to open the plate into a horizontally positioned flat stand for the child to lift. After ensuring the child's safety, slowly pull the entire device setup outwards from the borewell. As a result, using this mechanism, the child can be safely removed from the borewell.
