AI Technical Summary
During the inspection process, existing pipe wall crawlers suffer from dust affecting image acquisition quality and unclear images when moving, resulting in low accuracy of inspection results.
A crawler for inspecting the inner wall of a pipeline in water conservancy projects was designed, comprising a power component, a transmission component, a hollow shaft, and a sleeve. The power component enables the hollow shaft to rotate, driving the flushing component and the vision inspection component to rotate and maintain a fixed state for image acquisition. The transmission component, in conjunction with the telescopic component, enables the crawler to move inside the pipeline.
This ensures the clarity of the images captured on the inner wall of the pipeline and the accuracy of the detection. By acquiring images through omnidirectional flushing and a fixed state, the reliability of the detection results is improved.

[0058] Shell 22, shell 22 is fixed on the side wall of connecting rod 2, and one-way structure is arranged in shell 22, so that roller 3 can only rotate in one direction.
[0059] Through the action of 21, 3 on each 2 is in contact with the pipeline inner wall, so that the crawler can be in the pipeline;
[0060] It is worth mentioning that the one-way structure mentioned above can be a one-way rotation mechanism composed of a ratchet and a toothed gear, or any structure that can ensure the one-way rotation of the roller 3. Since the ratchet and toothed gear structure is a mature prior art and is not the innovation point of the present application, it will not be described again.
[0061] Further, the telescopic assembly comprises:
[0062] The plate body 10 is provided with a plurality of telescopic rods 11 on the side wall, and the telescopic end of each telescopic rod 11 is fixed to the nearest support seat 1. The plate body 10 is rotationally connected with the sleeve 12.

[0067] During the rotation of the hollow shaft 5, the camera 7 can be rotated by the fixed plate 6, and the spray head 9 can also be rotated by the support frame 8, so that the camera 7 can collect images of all parts of the inner wall of the pipeline, and the water output by the spray head 9 can also flush the inner wall of the pipeline in all directions.
[0068] Further, it also comprises:
[0069] The communication seat 16 is fixed with the support 4, and the communication seat 16 is rotationally connected with the hollow shaft 5;

[0076] A transmission belt 20 is sleeved on the two pulleys 19.
[0077] When the crawler needs to move, the switches of the plurality of 18 on the two 17 are turned on. When the 18 is turned on, the corresponding 18 on the two 17 attract each other, and then drive the 17 on the 5 to rotate in the process of the rotation of the 5, drive the other 17 to rotate through the magnetic force, so as to drive the 12 to rotate. In the process of the rotation of the 12, the 13 is retracted into the 12 through the action of the 13, so as to make the two 1 close to each other. Then, the reverse rotation of the 5 is driven by the 14, so that the 13 extends out of the 12, so as to make the two 1 far away from each other.

[0079] Then, the switch of the 14 is turned on. When the 14 works, the 5 is driven to rotate through the 20 and the two 19. In the process of the rotation of the 5, the 7 is driven to rotate through the 6, and the picture of the inner wall of the pipeline is taken by the 7 for visual detection.
[0080] If the inner wall of the pipeline needs to be flushed, the 15 needs to be connected with the high-pressure water pump. The high-pressure water pump pumps water into the 16 through the 15, and then into the 9 through the 5, and finally sprays out of the 9. In the process of the rotation of the 5, the 9 is driven to rotate, so as to realize the omnidirectional flushing of the inner wall of the pipeline, so as to facilitate the clarity of the pictures collected by the 7, and thus ensure the accuracy of the detection of the inner wall of the pipeline.
[0081] When the crawler needs to move, the switches of the plurality of 18 on the two 17 are turned on. When the 18 is turned on, the corresponding 18 on the two 17 attract each other, and then drive the 17 on the 5 to rotate in the process of the rotation of the 5, drive the other 17 to rotate through the magnetic force, so as to drive the 12 to rotate. In the process of the rotation of the 12, the 13 is retracted into the 12 through the action of the 13, so as to make the two 1 close to each other. Then, the reverse rotation of the 5 is driven by the 14, so that the 13 extends out of the 12, so as to make the two 1 far away from each other. The forward and reverse rotation of the 14 is periodically controlled, so as to realize the movement of the crawler on the inner wall of the pipeline.
