[0049] Example 3

[0050] The difference between this embodiment and embodiment 2 is that it also includes a drive module 23, an aviation battery 20, a preset program module 24 and a remote control module 25. The drive module 23 is arranged on the front chassis 1 and the rear chassis 2, and the other modules are arranged on the rear chassis 2.

The remote control module 25 is used to communicate and connect the equipment with the remote terminal device, which is conducive to realizing remote control by the operator, mastering the cleaning progress, etc.

[0051] The working process is described in detail below in conjunction with Example 2:

[0052] The front chassis 1 and the rear chassis 2 are sequentially mounted on the pipe, and the tension spring 21 and the tension spring buckle 22 are locked. The driven wheel 9 moves along the slide rail 14 under the action of the spring 13, and its inner surface is pressed against the outer wall of the pipe. At this time, the driving wheel 8 and the driven wheel 9 are tightly fitted against the outer wall of the pipe. The front chassis 1 and the rear chassis 2 are both provided with a set of driving wheels 8 and driven wheels 9, and each driving wheel 8 and driven wheel 9 works synchronously.

[0053] According to the actual outer diameter of the pipe, the first telescopic mechanism 19 and the second telescopic mechanism 26 are adjusted so that the rotating brush head 15 can roll and brush the pipe, and the sponge block 3 can maintain appropriate friction with the pipe and move along the length direction of the pipe.

[0054] The first drive motor 11 and the second drive motor are started, and under the action of the driving wheel 8, the device as a whole moves along the length direction of the pipeline. During the movement, the rotating brush head 15 performs rolling brushing to clean the outer wall of the pipeline. While the rotating brush head 15 is cleaning, the nozzle 17 sprays the clean water in the water storage bottle 16 onto the surface of the pipeline to improve the cleaning effect of the rotating brush head 15. The device continues to move along the length direction of the pipeline. When the sponge block 3 moves to the area where the rolling brush has been, the clean water remaining on the outer wall of the pipeline is wiped off, completing the cleaning work of the pipeline.
