In the process of pulling the pull rope 10, the guide wheel 8 at the tail of the support arm 7 will abut against the inner wall of the pipe, so that the first cartridge seat 1 and the second cartridge seat 6 can be suspended in the center of the pipe, and the rotating cleaning member will not deviate or shake when moving, so that the inner wall of the first cartridge seat 1 can be stably cleaned.
[0023] The elastic force of the spring structure can be adjusted by adjusting the knob, thereby controlling the maximum opening angle of the support arm 7, so that the cleaning device can be adapted to pipes of different diameters and has a wider range of applications.
[0024] The rotary cleaning member includes a rotating block 2 and a motor 3. The mounting end of the motor 3 is fixedly connected to the end of the first cartridge seat 1 away from the second cartridge seat 6. The output end of the motor 3 is fixedly connected to the rotating block 2. A plurality of rotary cleaning members 4 are arranged outside the rotating block 2. Each rotary cleaning member 4 is evenly arranged in the circumferential direction of the axis of the rotating block 2. When the first cartridge seat 1 moves in the pipeline, the motor 3 installed at the rear end of the first cartridge seat 1 drives the rotating block 2 to rotate, and the rotating block 2 drives the rotary cleaning member 4 to rotate, and the rotary cleaning member 4 cleans the dirt on the inner wall of the pipeline.
[0025] More specifically, the rotating cleaning member 4 includes a plurality of brush plate boxes 41, which are fixed on the outside of the rotating block 2. A floating plate 42 is provided at one end of the brush plate box 41 away from the rotating block 2.

The nut 12 is disposed at the lower end of the assembly ring 14 and is rotatably connected to the assembly ring 14. By rotating the nut 12, the nut 12 can move along the adjustment bolt 11. When the nut 12 rises, the assembly ring 14 will push the first spring 13 to open the support arm 7 to a larger angle. Due to the self-locking property of the threaded connection, the nut 12 will not slip after it stops rotating.
[0028] In order to facilitate the staff to rotate the nut 12 and adjust the tension of the first spring 13, a convex block is provided on the outside of the nut 12, and the convex block is fixed on both sides of the nut 12 and is integrally formed with the nut 12. When the nut 12 is rotated, the convex block on the outside of the nut 12 can provide assistance for the user to rotate.
[0029] The difference from the existing dirt cleaning device is that the spring structure is arranged between the second cartridge seat 6 and the support arm 7, which can prop up the support arm 7 outward, so that the first cartridge seat 1 and the second cartridge seat 6 can be suspended in the center of the pipe, and the rotating cleaning part will not deviate or shake when moving, and the inner wall of the first cartridge seat 1 can be stably cleaned.
