[0025] A slip ring 7 is limitedly and slidably sleeved on the outer surface of the connecting column 4, and a plurality of brushes 8 are fixedly arranged on the outer peripheral surface of the slip ring 7. A plurality of limit blocks 9 are fixedly arranged on the inner wall of the inner ring of the slip ring 7, and a plurality of limit grooves 16 are opened on the outer surface of the connecting column 4. The number of the limit blocks 9 is equal to and corresponds to the number of the limit grooves 16 one by one, and each limit block 9 is limitedly and slidably arranged in the corresponding limit groove 16. In addition, both ends of the limit groove 16 are blocked to prevent the slip ring 7 from separating from the connecting column 4.

[0026] As Figure 1As shown in the figure. A resilient member is provided at one end of the slip ring 7 close to the support rod 1. The resilient member includes a spring 12. A retaining ring 13 is fixedly sleeved at one end of the connecting column 4 close to the support rod 1. The retaining ring 13 is located on the right side of the slip ring 7. The spring 12 is sleeved on the outer surface of the connecting column 4. One end of the spring 12 is fixedly connected to the slip ring 7, and the other end of the spring 12 is fixedly connected to the retaining ring 13.

[0027] As Figures 1-3 shown, a transmission member is provided between the cleaning disk 6 and the slip ring 7. The transmission member includes a first push rod 10. A plurality of first push rods 10 are fixedly arranged at equal intervals on one side of the slip ring 7 facing the cleaning disk 6. The plurality of first push rods 10 are circumferentially arrayed about the central axis of the slip ring 7. A support ring is coaxially fixedly arranged on one side of the cleaning disk 6 facing the slip ring 7. The support ring sleeves the placement groove for blocking the connecting column 4. A plurality of second push rods 11 are fixedly arranged at equal intervals on one side of the support ring facing the slip ring 7.

And, the opposite ends of the first push rod 10 and the second push rod 11 are in contact transmission cooperation. For pushing the brush 8 to slide along the central axis of the connecting column 4.

[0029] Working principle of Embodiment 1: When in use, the device is placed inside the pipeline. The electric push rod 2 is started, and the telescopic shaft of the electric push rod 2 is controlled to extend, so as to push the roller 3 to slide in a direction away from the connecting column 4, so that all the rollers 3 are in contact with the inner wall of the pipeline, thereby supporting the device.

[0030] Subsequently, the driving motor is started to control the roller 3 to rotate. The rotation of the roller 3 will push the device to move inside the pipeline. During the movement of the cleaning disk 6, the sundries in the pipeline will be cleaned, and the brush 8 will clean the inner wall of the pipeline after cleaning.

[0031] While the roller 3 is rotating, the motor 5 is started. The output shaft of the motor 5 can drive the cleaning disk 6 to rotate, thereby improving the cleaning efficiency of the cleaning disk 6. At the same time, the rotation of the cleaning disk 6 will drive a plurality of second push rods 11 to rotate around the central axis of the cleaning disk 6 through the support ring. During the rotation of the second push rod 11, it will intermittently contact the first push rod 10.

[0032] When the second push rod 11 contacts the first push rod 10, as the cleaning disk 6 continues to rotate, the second push rod 11 will push the first push rod 10 to slide in a direction away from the cleaning disk 6, thereby driving the slip ring 7 to slide in the limiting groove 16 along the groove direction of the limiting groove 16 in a direction away from the cleaning disk 6, and then driving the brush 8 to slide in the same direction. During this process, the compression deformation amount of the spring 12 gradually increases.

[0033] When the smooth arc surface end of the second push rod 11 crosses the smooth arc surface end of the first push rod 10, with the continuous rotation of the cleaning disc 6. Under the elastic action of the spring 12, the slip ring 7 will slide along the groove direction of the limit groove 16 in the limit groove 16 towards the direction close to the cleaning disc 6, thereby driving the brush 8 to slide in the same direction.

[0034] Through the continuous reciprocating sliding of the brush 8, the cleaning effect of the brush 8 on the inner wall of the pipeline is effectively improved, avoiding the residue of stain blocks, and further improving the cleaning effect of the device.

[0035] Embodiment 2: As Figure 4 shown, the difference between this Embodiment 2 and Embodiment 1 is that: the transmission member includes a first magnet block 14, and a number of first magnet blocks 14 are fixedly arranged at equal intervals on the side of the slip ring 7 facing the cleaning disc 6. A number of second magnet blocks 15 are fixedly arranged at equal intervals on the side of the support ring facing the slip ring 7, and the opposite ends of the first magnet block 14 and the second magnet block 15 have the same magnetic poles.

[0036] The working principle of Embodiment 2: The rotation of the cleaning disc 6 will drive a number of second magnet blocks 15 to rotate around the central axis of the connecting column 4 through the support ring.

[0037] When the second magnet block 15 approaches the first magnet block 14, the first magnet block 14 will drive the slip ring 7 to slide along the groove direction of the limit groove 16 in the limit groove 16 towards the direction away from the cleaning disc 6. During this process, the compression deformation amount of the spring 12 gradually increases.

[0038] When the second magnet block 15 moves away from the first magnet block 14, under the elastic action of the spring 12, the slip ring 7 will slide along the groove direction of the limit groove 16 in the limit groove 16 towards the direction close to the cleaning disc 6.
