A fixed shaft 7 is fixedly installed on the top center of the turntable 3, and an adjusting gear 8 is rotatably installed on the outside of the fixed shaft 7. The adjusting gear 8 is provided with an arc hole 9 arranged around the center, and the arc hole 9 is scattered on the adjusting gear 8. The cleaning component 4 is arranged at the top of one end inside the chute 5 and is connected to the arc hole 9. By giving the adjusting gear 8 a rotational force through external force, the adjusting gear 8 can adjust the position of the cleaning component 4 in the chute 5 through the arc hole 9, so that the end of the cleaning component 4 away from the chute 5 can be extended toward the outside of the turntable 3. If the cleaning component 4 is driven deep into the pipeline by the turntable 3, the end of the cleaning component 4 can always be close to the inner wall of the pipeline by rotating the adjusting gear 8, and effective cleaning can be achieved regardless of the size of the pipeline diameter.

[0033] In order to enable the cleaning assembly 4 to effectively clean the inner wall of the pipeline, in this embodiment, the cleaning assembly 4 includes a slide rod 10, which is inserted into the chute 5 at one end of the slide rod 10 toward the turntable 3, and a guide post 11 is fixedly installed on the side of the slide rod 10 located inside the chute 5 toward the adjusting gear 8. The guide post 11 is slidably arranged in the arc hole 9, and the end of the guide post 11 away from the slide rod 10 passes through the arc hole 9 and is fixedly installed with a stopper 12. The end of the slide rod 10 away from the turntable 3 is fixedly installed with an arc plate 13, and a cleaning brush 14 is fixedly installed on the side of the arc plate 13 away from the slide rod 10. When the adjusting gear 8 rotates, the guide post 11 can be driven to move through the arc hole 9, and the guide post 11 will then drive the slide rod 10 to slide in the chute 5, and then the slide rod 10 can drive the cleaning brush 14 toward the inner wall of the pipeline through the arc plate 13.

The wire sleeve 20 is perpendicular to the adjusting plate 18, and a screw rod 21 is screwed inside the wire sleeve 20. A positioning column 22 is fixedly installed on the end of the screw rod 21 facing the adjusting plate 18, and a ring-shaped positioning groove 23 is provided on the end surface of the adjusting plate 18 away from the mounting bracket 15. When the positioning column 22 is away from the positioning groove 23, the adjustment plate 18 can be rotated, and the adjustment plate 18 drives the driving gear 17 to rotate through the adjusting shaft 16. The driving gear 17 can drive the adjusting gear 8 meshing therewith to rotate, thereby realizing the adjustment of the cleaning component 4. When the cleaning component 4 is adjusted into place, by twisting the screw rod 21, the screw rod 21 can drive the positioning column 22 to move toward the positioning groove 23. When the positioning column 22 is tightly against the inside of the positioning groove 23, the adjusting plate 18 can be positioned through the positioning groove 23, and then the driving gear 17 can be indirectly locked to prevent the adjusting gear 8 from rotating independently.

[0035] In order to ensure that the positioning column 22 can be stably positioned with the positioning groove 23, in this embodiment, the bottom wall of the positioning groove 23 is provided with anti-slip grooves (not shown), and the end of the screw rod 21 away from the positioning column 22 is also fixedly mounted with an adjustment handle 24.

The bottom end of the drive shaft 28 is rotatably mounted on the lifting plate 34 via the bearing seat 35. When the hydraulic cylinder 33 is started, the hydraulic cylinder 33 can drive the drive shaft 28 to move up and down through the lifting plate 34. At this time, the drive shaft 28 can drive the turntable 3 to rise and fall synchronously, thereby changing the radial position of the cleaning brush 14 inside the pipe.

[0038] In order to enable the drive shaft 28 to be driven to rotate by the drive motor 30 and to be driven to rise and fall by the hydraulic cylinder 33, in this embodiment, the assembly part 27 includes a fixed sleeve 36 fixedly mounted on the support frame 26, and an assembly bearing 37 is installed inside the fixed sleeve 36.

A vertical groove 42 is opened on the outer wall of the driving shaft 28. The vertical groove 42 is arranged along the length direction of the driving shaft 28. When the driving shaft 28 passes through the connecting sleeve 40, the vertical groove 42 is tightly fitted with the convex strip 41.

[0039] When the drive motor 30 is started, the active pulley 31 will drive the hollow shaft 38 to rotate synchronously through the transmission belt 32. At this time, the hollow shaft 38 will drive the drive shaft 28 to rotate synchronously through the connecting sleeve 40. When the hydraulic cylinder 33 is started, the lifting plate 34 will drive the drive shaft 28 to rise and fall synchronously through the bearing seat 35. At this time, the drive shaft 28 will slide along the convex strip 41 on the inner wall of the connecting sleeve 40 through the vertical groove 42 without affecting the drive rotation of the driven pulley 39.
