A moving block 45 is slidably sleeved on the outer wall of the limiting rod 44. The rack 43 is meshed with a gear 46. A through hole is opened on the top of the moving block 45, and the gear 46 passes through the through hole and is meshed with the rack 43, so that the gear 46 and the rack 43 are better meshed, thereby improving the stability of the rotation of the gear 46 and making the movement of the moving block 45 more stable. The gear 46 is fixedly sleeved with a rotating shaft 47. One end of the outer wall of the rotating shaft 47 is fixedly sleeved with a bevel gear one 48, and the other end is fixedly connected with a motor 49 through a coupling. The motor 49 is a reduction motor 49 and is fixedly installed on the top of the moving block 45 through a motor bracket. The rotation speed of the motor 49 can be reduced, and the transmission of the motor 49 can be reversed, thereby improving the cleaning strength of the scraping blade 412 and the depth of the moving scraping blade 412, ensuring the cleaning effect.

After the rotation of the first bevel gear 48, the first bevel gear 48 meshes with and drives the second bevel gear 410 to rotate. The second bevel gear 410 drives the rotating rod 411 to rotate, and the rotating rod 411 drives the scraping blade 412 to rotate, so that the scraping blade 412 continuously rotates to clean the dirt on the pipeline wall. Among them, the gear 46 and the rack 43 are in meshing transmission, so as to drive the moving block 45, the rotating rod 411 rotatably connected to the fixing plate 7, and the scraping blade 412 connected to the rotating rod 411 to realize reciprocating motion, so as to clean different depths in the pipeline. The operation is simple and efficient.
