The positioning assembly can position the overall device while transmitting the information of the rock layer to the detector 2 after the tail vertebra 43 is inserted into the rock layer. Figure 13The telescopic member comprises a screw rod 45, a threaded cover 50, a U-shaped frame 51, a roller 52, a transmission gear 53 and a rack 49. The top end of the screw rod 45 is rotationally connected with the swing rod 44. The U-shaped frame 51 is slidingly connected with the connecting ring 42. The U-shaped frame 51 is rollingly connected with the roller 52. In this way, the sliding connection between the threaded cover 50 and the connecting ring 42 cannot be separated. The roller 52 is rotationally connected in the U-shaped frame 51. The roller 52 penetrates through the connecting ring 42. The roller 52 is rollingly contacted with the inner wall of the connecting ring 42. The bottom end of the screw rod 45 extends into the threaded cover 50 and is threadedly connected with the threaded cover 50. When the threaded cover 50 rotates, the telescopic range of the threaded cover 50 and the screw rod 45 can be expanded or reduced. The threaded cover 50 is rotationally connected with the top of the U-shaped frame 51. The rack 49 is fixedly installed on the top of the connecting ring 42. The transmission gear 53 is fixedly sleeved on the threaded cover 50. The transmission gear 53 is meshingly and transmissionally connected with the rack 49.

When the swing rod 44 rotates, the longitudinal movement range of the tail vertebra 43 can be expanded. In this way, the tail vertebra 43 can be inserted into the rock layer.

[0051] In this embodiment, when the rock layer in the mine needs to be detected, first fix the traction rope 55 with the wellhead, then start the driving motor 14 to drive the connecting shaft 15 to rotate, when the connecting shaft 15 rotates, the second worm 37 and the second worm wheel 36 can drive the synchronous shaft 35 to rotate, when the synchronous shaft 35 rotates, the second synchronous wheel 38 can be driven to rotate, so that the synchronous belt 33 can move, at this time, under the transmission action of the synchronous belt 33, the first synchronous wheel 12 can drive the rotating shaft 10 to rotate, when the rotating shaft 10 rotates, the reel 11 can be driven to rotate, so that the traction rope 55 starts to unroll, and when the connecting shaft 15 rotates, the first bevel gear 16 and the second bevel gear 20 can drive the transmission shaft 17 to rotate, at this time, the plurality of first worms 18 can rotate with the transmission shaft 17, under the meshing transmission action of the plurality of first worms 19, the plurality of supporting shafts 3 can rotate synchronously and in the same direction, at this time, the plurality of first tank wheels 4 and the plurality of second tank wheels 6 can rotate synchronously, so that the first tank chain 5 and the second tank chain 7 can run, so that the device can move along the mine to the inside of the mine, that is, the detector 2 can be transported into the mine, and when the device moves, the release speed of the traction rope 55 is consistent with the moving speed of the device, so that the traction rope 55 can always have traction, which can prevent the device from being unstable during movement, and using the first tank chain 5 and the second tank chain 7 as the moving execution carrier can prevent the device from being concave during movement, so compared with the traditional wheel walking, the walking mode of the device has good stability, and the geological conditions that can be coped with are also more, so that the application range of the device can be enhanced;

[0052] In the process of the device running, the two electromagnets 58 can be energized. Since the side close to each other of the two electromagnets 58 is N-pole, after the two electromagnets 58 are energized, repulsive force can be formed to push the positioning plate 56 to move upward. When the positioning plate 56 moves upward, the transmission roller 23 can be driven by the slide shaft 22 to move upward until the driving gear 26 meshes with the clutch gear 27 to drive. Since the driving gear 26 rotates with the transmission shaft 17, the clutch gear 27 can be driven to rotate under the action of the rotating force of the driving gear 26. At this time, the transmission roller 23 can be rotated. Since the annular groove 39 and the stop shaft 40 in the moving ring 24 can be matched, the stop shaft 40 can move transversely reciprocatingly when the transmission roller 23 rotates, so that the moving ring 24 moves transversely reciprocatingly in the left-right direction. When the moving ring 24 moves, the connecting rod 28 can be driven to move synchronously by the transmission rod 25. When the connecting rod 28 moves to the left side, the rectangular ring 29 can be driven to move. The rectangular ring 29 has a pushing force to move to the left side. The two slide plates 32 and the two positioning shafts 33 can make the two rotating rods 30 rotate to the side away from each other, and the two slide plates 32 can move away from each other, so that the two compression springs 34 are in a stressed and compressed state. When the connecting rod 28 moves to the right side, the rectangular ring 29 can move with it, losing the pushing force to the slide plate 32. At this time, the two compression springs 34 in the stressed state can push the two slide plates 32 to move close to each other, and the two slide plates 32 can move to the right side with the rectangular ring 29, so that the two rotating rods 30 rotate to the side close to each other. Therefore, when the moving ring 24 moves transversely reciprocatingly, the two rotating rods 30 can reciprocate. When the rotating rod 30 rotates, the cleaning brush 31 can be driven to rotate, so that the device can clean the road surface in the process of moving, and prevent the first tank chain 5 and the second tank chain 7 from slipping due to the gravel scattered in the mine, facilitating the device to walk in the mine;

[0053] After the detector 2 is moved to the designated position, the electric push rod 54 can be started to pull the mounting ring 46 to the right side, so that the mounting ring 46 loses the supporting force on the mounting rod 47, and the mounting rod 47 can be moved downward to drive the swing rod 44 to rotate downward, which can drive the screw rod 45 to move downward in an arc shape, and at the same time, the connecting ring 42 can be moved downward to drive the tail vertebra 43 to move downward, and when the swing rod 44 rotates downward, the threaded cover 50 can slide to the right along the connecting ring 42, and when the threaded cover 50 moves, the threaded cover 50 can be driven to rotate by the meshing transmission of the transmission gear 53 and the rack 49, and when the threaded cover 50 rotates, the threaded cover 50 can move downward along the screw rod 45, so as to increase the range of downward movement of the tail vertebra 43, until the tail vertebra 43 is inserted into the rock layer, at this time, the connecting ring 42 does not separate from the fixed cover 41, and the tail vertebra 43 can be used to brake the device, and the spring wire 48 connected to the tail vertebra 43 can realize the electrical connection between the tail vertebra 43 and the detector 2, so that the tail vertebra 43 can transmit the information in the rock layer to the detector 2, and the detector 2 can detect the rock layer.

[0054] The embodiment provides a use method of a downhole detector for geophysical exploration, and the method comprises the following steps:

[0055] S1: The traction rope 55 is connected and fixed with the mine shaft mouth.

[0056] S2: The driving motor 14 is started to drive the connecting shaft 15 to rotate, so that the traction rope 55 is unwound and the length of the traction rope 55 is extended.
