The upper end of leading screw 39 and the lower end of umbrella axis 34 stretch into axle sleeve 38 from axle sleeve 38 two ends respectively, and the upper end of umbrella axis 34 is connected with the upper plate 1 of supporting structure by screw thread. The shaft sleeve 38 is fixedly connected with the umbrella shaft 34 through the pin hole on it, the upper end of the lead screw 39 is axially positioned through the shaft sleeve 38, and the lower end is connected with the motor 7 through the shaft coupling 10, 28, and the motor 7 is fixed on the supporting structure on the upper middle plate 3'. A nut is engaged on the lead screw 39, and the umbrella pole connecting piece is engaged on the nut. During work, the screw 39 is driven by the motor 7 to rotate, and the nut moves up and down with the rotation of the screw, thereby driving the umbrella pole connecting piece 41 to lift up and down to complete the retractable function of the umbrella mechanism.

[0027] like Image 6 As shown, the clamping mechanism is a screw drive mechanism, which is used to make the mechanical arm pivot at a small radial angle during the rescue process, so as to achieve the purpose of fastening the person in the deep well rescuer. The clamping mechanism is wrapped with a ball screw 8 about 300mm long, a push plate, three springs 47, a motor, and three sets of drive rod assemblies with a length of about 100mm, and each set of drive rod assemblies includes three connecting rods 43, 44 , 46. A nut 9 is engaged on the lead screw 8, and the push plate is engaged on the nut through its central hole. One end of each spring is connected to the part fixedly sleeved on the lead screw, and the other end is connected to a transmission rod assembly. The upper end of the leading screw 8 is connected to the motor fixed on the lower middle plate 3 through a shaft coupling, and the lower end is connected with the central shaft 6 of the lower plate 4 . When working, the motor 7 drives the lead screw to rotate, and the nut moves up and down with the rotation of the lead screw, thereby driving the push plate to lift up and down. The lift of the push plate causes the transmission rod assembly to pivot at a small radial angle, and then after being driven by the drive rod Drive the lifting mechanism to rotate inward or outward in the radial direction to complete the clamping function.
[0028] like Figure 7 As shown, the position adjustment mechanism is a set of gear transmission mechanism, which is used to adjust the mechanical arm to a suitable position in the circumferential direction so as to extend the mechanical arm into the well. The positioning mechanism includes three pinion shafts 21, 30 and 32 engaged with the transmission teeth of the lower plate 4 of the supporting structure, and each pinion shaft is installed between the upper connecting plate 23 and the lower connecting plate 23' respectively, and the upper connecting plate One end of the plate 23 and the lower connecting plate 23' is respectively provided with mounting holes to be fixed on the central axis 6 of the lower plate 4, and the other ends are connected to each other by connecting pieces 22, 31, 33, and the connecting pieces 22, 31, 33 are connected to the upper and lower sides. The plates 23, 23' are preferably interconnected by bolt-nut assemblies. The connectors 22, 31, 33 are directly connected to the mechanical arm. Each upper connecting plate 23 is provided with motor bases 25 and 26, and each motor base 25 and 26 is respectively fixed with a motor 27. During work, the three pinion shafts 21, 30 and 32 are driven to rotate by the three motors 27, so that the position adjustment mechanism rotates along the transmission teeth to achieve the purpose of adjusting the circumferential position of the mechanical arm.
[0029] like Figure 8 and Figure 9 As shown, the lifting mechanism is a connecting rod telescopic mechanism, which is used to directly contact the human body and protect the person in the deep well rescue device. The lifting mechanism includes three T-shaped beams 11 with a length of about 1500mm, and one end of each T-shaped beam is connected with the positioning mechanism through a connecting piece 12, and the connecting piece 12 can be a screw or a pin. A motor base 18 is fixedly installed at about 100 mm below the position adjustment mechanism on each T-shaped beam 11, one end of the output shaft of the motor is installed on the motor base, and the other end is installed on the bearing 20, and the output shaft of the motor is manufactured Become leading screw 19. A nut is engaged on the leading screw 19, and a slide block 12 is fixed on the nut, and the slide block 12 is sleeved on the T-shaped beam through a through hole thereon. During work, the rotation of the leading screw 19 causes the nut to move up and down along the leading screw 19, so that the slide block moves up and down with the T-shaped beam as the guide rail. A transmission rod assembly is connected to the slide block, and the transmission rod assembly may include two push rods 14 . The push rod 14 is connected with the mechanical claw at the beam tail 15 by a pin, so that the up and down movement of the slider makes the push rod push the mechanical claw at the beam tail 15. Each mechanical claw includes three sets of support rods 16, 17, each set of support rods is composed of two connecting rods with a length of about 120mm, and the connecting rods are connected by fixing parts 24, 29, and the fixing parts may be pins. The mechanical claw has a structure that can be expanded or contracted, and it expands or contracts as the slider moves up and down during work. When it is in a suitable position below the person, it becomes the unfolded state, thereby enclosing the trapped person in the lifting mechanism. Preferably, the lifting mechanism can also be provided with soft materials, such as rubber pads, sponge pads and the like.
[0030] The master control system is a set of motor drive system controlled by computer, which is used to control the movement of the mechanism in real time. It includes computer, microcontroller, six motor driver boards and some wires. Rescuers on the ground control the operation of the motor by operating the computer to drive the movement of the rescuer to implement rescue.
[0031] The communication device includes a lighting system, a camera and a communication system, and circuit boards corresponding to the lighting system, the imaging system and the communication system are connected to a computer to obtain information about people trapped underground.
[0032] The working process of the deep well rescue device of the present invention will be described below.
[0033] Tie the rope on the rope fixing ring 45, hang it vertically from the ground into the well, monitor the camera, make the rescuer stop above the trapped person, drive the motor 7 of the positioning mechanism, drive the lead screw 39 to rotate, and the positioning mechanism launches, so that The wheels 42 contact the well wall and do not shake down the well, and the device completes the positioning. The rescuers on the ground observed the posture of the trapped person in the well through the camera, looking for three gaps of about 20mm. After finding a suitable gap, drive the motor 27 of the positioning mechanism to make the positioning mechanism work, and the positioning mechanism adjusts the circumferential positions of the three groups of mechanical arms so that the three groups of mechanical arms are aligned with the gaps found. After the position is adjusted, the rope is slowly lowered, and the rescuer moves down slowly along the well wall, so that each mechanical arm extends under the trapped person, and the mechanical claws of the lifting mechanism are in a contracted state at this time. When the mechanical arm stretched into the position that the fixing part 29 arrived below the trapped person, the leading screw 19 of the lifting mechanism was driven to rotate, so as to push the support rod 17 through the downward movement of the push rod 14 until the upper part of the support rod 17 was close to the level position, so that the mechanical rotation of the lifting mechanism is in the unfolded state, and the trapped person is surrounded by the mechanical claws of the lifting mechanism. Then, the screw 8 that drives the clamping mechanism rotates, and the connecting rods 43, 44, 46 are pushed by the push plate 9 so that the clamping mechanism pivots in the radial direction to clamp the trapped person. Finally, the motor 7 that drives the positioning mechanism puts up the positioning mechanism, and the people and the deep well rescuer are pulled out of the well by the rope, and the rescue task is completed.
[0034] It should be understood that standard connections, such as nuts, threads, pins, etc., have been omitted from the above figures for the sake of clarity. These standard connectors and specific connection methods have been described in text descriptions, and those skilled in the art will be able to realize the interconnection of various parts through these text descriptions and drawings.
[0035] The above-mentioned embodiments are only for the purpose of illustration, and do not constitute a limitation to the deep well rescue device of the present invention. The invention can also be used to rescue animals trapped down a well, or to retrieve objects that have fallen down a well.
