[0022] It should be noted that the specific models and specifications of the PLC controller 7, the industrial camera 20 and the infrared sensor 21 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it is not repeated here.

[0023] Furthermore, the rotating clamping structure includes a ring 9, a screw 10 evenly distributed in the circumferential direction, a fixing rod 11, a knob 12, and a clamping block 13. The ring 9 is rotatably connected to the inner wall of the support column 2, the screw 10 is threadedly connected to the outer wall of the ring 9, the fixing rod 11 is slidably connected to the outer wall of the ring 9, and the clamping block 13 is rotatably connected to one end of the screw 10.

[0024] Among them, the rotating clamping structure is to manually drive the sleeve 3 or the extension rod 4 to rotate. Under the drive of the ring 9, the sleeve 3 can rotate around the rotation axis of the ring 9, which is convenient for testing. The screw 10 can be driven to rotate by manually rotating the knob 12. The screw 10 drives the clamping block 13 away from the outer wall of the sleeve 3 and then placed on the outer wall of the extension rod 4 for clamping. The length of the sleeve 3 and the extension rod 4 can be adjusted to adapt to tunnels of different sizes.

[0025] Furthermore, the knob 12 is fixedly connected to the other end of the lead screw 10 , and one end of the fixing rod 11 is fixedly connected to the outer wall of the clamping block 13 .

[0027] Furthermore, the mounting structure includes an insert block 14, sliding holes 15 evenly distributed circumferentially, a spring 16, and a limiting protrusion 17.

[0028] The outward end of the limiting protrusion 17 is semicircular, and when the inserting block 14 completely enters the inner wall of the sleeve 3 , the limiting protrusion 17 can completely enter the sliding hole 15 .

[0029] Furthermore, the other end of the spring 16 is fixedly connected to the outer wall of the limiting protrusion 17 , and the position and size of the limiting protrusion 17 are adapted to the position and size of the sliding hole 15 .

[0033] Working principle: first take out each component, insert the sleeve 3 into the ring 9, then manually rotate the knob 12 to drive the screw 10 to rotate, the screw 10 pushes the clamping block 13 to abut against the outer wall of the sleeve 3 and clamp it tightly, then align the insert block 14 with the top end of the sleeve 3 for insertion and installation, the limiting protrusion 17 will be squeezed into the sliding hole 15, and the spring 16 will be squeezed at the same time. When reaching the position of the limiting hole 6, the limiting protrusion 17 returns to its original position under the elastic action of the spring 16 and connects with the limiting hole 6 to achieve limitation.

[0034] When testing the inner wall of a tunnel, if the length of the sleeve 3 is not enough, the extension rod 4 can be rotated manually to extend the length of the rod backwards, and then the knob 12 can be rotated manually again to drive the lead screw 10 to rotate, and the lead screw 10 drives the clamping block 13 away from the outer wall of the sleeve 3, and then placed on the outer wall of the extension rod 4 for clamping, so that the length of the sleeve 3 and the extension rod 4 can be adjusted to adapt to tunnels of different sizes, thereby adapting to bridge tunnels of different sizes, and the inner wall of the tunnel can be inspected at close range, and the rubber roller can roll with the inner wall of the tunnel, so that the industrial camera can shoot closer to the inner wall of the tunnel, and the shooting is clearer. And it can adapt to different tunnel sizes and shapes.
