[0034] Specific working principle:

[0035] First, if Figure 1-3 and Figure 5-7 As shown, the staff puts the detection head 3 into the center disk 22 and rotates the connecting rod 27. Since the connecting rod 27 is located on the opposite side of the two fixed rods 23, when the connecting rod 27 rotates, it pushes the two fixed rods 23 to rotate, and drives the center disk 22 to rotate in the direction away from the connecting rod 27. The rotation of the center disk 22 drives the connecting rod 1 25 to rotate in the direction close to the detector. Since one end of the connecting rod 1 25 is rotatably connected to the center disk 22, it will limit the connecting rod 1 25, so that the other end of the connecting rod 1 25 drives the flexible clamp 26 to rotate, so that the flexible clamp 26 clamps the detector. Because the flexible clamp 26 has a slight Elasticity, when the flexible clamp 26 clamps the detector, it will not cause damage to the detector; when the flexible clamp 26 clamps the detector, the staff feels that the connecting rod 27 cannot rotate, and pulls the connecting rod 27 upward, so that the connecting rod 27 pushes the rotating plate 44 to rotate away from the cavity 42, and passes through the partition 43 to enter the space between the partition 43 and the shell 41. Since the rotating plate 44 and the partition 43 are connected by a hinge, the rotating plate 44 can only rotate 90° and then automatically bounce back to its original position. When the connecting rod 27 enters the square hole between the partition 43 and the shell 41, the rotating plate 44 automatically rotates, so that the connecting rod 27 cannot enter the cavity 42 again;

[0036] It should be noted that: Figure 3 and Figure 5-6As shown, vertical lines are provided above the position where the rotating shaft 28 is connected to the second connecting rod 27, and the second connecting rod 27 is provided with a vertical groove, the size of the vertical groove is the same as the size of the vertical lines, when the second connecting rod 27 is pulled upward, the vertical groove and the vertical lines are engaged, so that the second connecting rod 27 cannot rotate, and at the same time, the two fixing rods 23 are fixed, so that the flexible clamping block 26 fixes the detector, preventing the detector from being bumped due to the complex environment when entering the well, thereby causing damage to the detection device.

[0037] Then, if Figure 1-2 and Figure 4 As shown, after the detector is fixed, the staff puts the walking mechanism 5 on the supporting structure on the well wall, and the slider 56 contacts the supporting structure at the beginning, and the supporting structure pushes the slider 56 to move inside the telescopic rod 2 53. Since the slider 56 is triangular in shape, the inclined surfaces on both sides of the slider 56 push the arc-shaped slider 562 to slide away from the slider 56 and stretch the spring 4 563 during the sliding process, so that the end of the arc-shaped slider 562 away from the slider 56 extends out of the limit block 561 and approaches each other, thereby hugging the supporting structure, so that the device is connected to the supporting structure; then the staff turns on the electromagnet 1 523 and the electromagnet 2 533, so that the fixed block 1 521 and the fixed block 2 531 compress the spring 2 522 and the spring 3 532 respectively, so that the telescopic rod 1 52 and the telescopic rod 2 53 are both in a contracted state, and at the same time starts the motor 51 to drive the telescopic rod 1 52 Rotation, when the end of the telescopic rod 1 52 away from the motor 51 rotates to above the protective shell 1, the telescopic rod 1 52 drives the telescopic rod 2 53 to rotate along, at this time, the telescopic rod 2 53 pulls the slider 56 away from the supporting structure, and the inclined surface of the slider 56 gradually reduces the restriction on the arc slider 562. The springs 4 563 on both sides return and pull the arc slider 562 away from each other, so that the arc slider 562 is separated from the supporting structure, and the telescopic rod 3 54 and the telescopic rod 4 55 rotate synchronously with the telescopic rod 2 53, which limits the telescopic rod 2 53. After the telescopic rod 2 53 rotates one circle, it will achieve partial displacement, so that the device can automatically run slowly and steadily underground without manual deployment. At the same time, when there is a problem with the detector, it is only necessary to control the rotation direction of the motor 51 to make the device automatically leave the mine, which can reduce the danger of work for the staff.

[0038] Finally, if Figure 1-2 and Figure 4 As shown, when the internal space of the mine is large and the temperature, pressure and dryness of the mine wall and the center position need to be detected, the staff only needs to turn off the power of electromagnet 1 523 and electromagnet 2 533, and spring 2 522 and spring 3 532 will push fixed block 1 521 and fixed block 2 531 away from electromagnet 1 523 and electromagnet 2 533 respectively, and extend telescopic rod 1 52 and telescopic rod 2 53, so that the protective shell 1 is close to the middle of the mine, which is convenient for the detector to detect the temperature, pressure and dryness of the middle of the mine.

[0039] The implementation modes of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
