[0025] Refer to Figure 1 - Figure 3The outer wall of the toothed plate 503 is engaged with a gear 505, and the displacement of the toothed plate 503 drives the gear 505 to rotate, thereby driving another toothed plate 503 disposed in a skew symmetry to displace, achieving the displacement effect of the two toothed plates 503 moving close to or away from each other. The bottom end of the gear 505 is rotatably connected with a support plate 506, and the outer wall of the support plate 506 is fixedly connected to the top plate 3. The support plate 506 limits and fixes the gear 505 and has a bearing effect, allowing the gear 505 to rotate in place. The outer wall of the top plate 3 is fixedly connected with a gas cylinder 501, and the output end of the gas cylinder 501 is fixedly connected with a fixed block 502. The operation of the gas cylinder 501 can control the displacement of the fixed block 502 through the output end of the telescopic rod. The bottom outer wall of the fixed block 502 is fixedly connected to the top outer wall of the toothed plate 503, and the fixed block 502 can drive the toothed plate 503 to displace. The inclined outer wall of the movable plate 507 is detachably connected with a sponge pad 508, and the flexible contact of the sponge pad 508 can avoid damaging the surface of the pipeline.

[0026] Referring to Figure 2 Figure 4 The top plate 3 is provided with a cleaning mechanism 6, which includes a sliding plate 603. The bottom outer wall of the sliding plate 603 is slidingly connected to the outer wall of the top plate 3, achieving a limiting effect. A rotating shaft 602 is rotatably connected to the inner wall of the sliding plate 603, achieving an installation effect for the rotating shaft 602, allowing the rotating shaft 602 to rotate stably. A cleaning cotton 605 is detachably connected to the bottom end of the rotating shaft 602. The cleaning cotton 605 can rotate under the rotation of the rotating shaft 602, clean the top of the pipeline, and be easily replaced. A rotating disc 601 is fixedly connected to the top end of the rotating shaft 602, which is convenient for personnel to control and rotate, thereby driving the rotating shaft 602 to rotate. A screw rod 606 is fixedly connected to the inner wall of the gear 505 and can rotate under the rotation of the gear 505. The two screw rods 606 are symmetrically arranged and limited. A threaded plate 604 is threadedly connected to the outer wall of the screw rod 606 and can vertically ascend and descend under the limiting effect.
