[0002] In a broad sense, a water conservancy project is a project built to prevent and control water disasters and develop and utilize water resources, including flood control, waterlogging control, irrigation, water supply, hydropower generation, shipping, water resource protection, soil and water conservation, as well as water-related projects in projects such as aquaculture, tourism, and improvement of the ecological environment. In the field of water conservancy projects, effective cleaning of the inner wall of pipelines is of great significance for ensuring the normal operation of the water conservancy system.

[0003] A patent document with the publication number CN118719728A discloses a pipeline cleaning device for water conservancy projects, including a first support rod, a second support rod, and a rotation adjustment mechanism. The rotation adjustment mechanism is arranged between the first support rod and the second support rod. The first support rod and the second support rod are respectively provided with the same adjustment connection mechanism. The adjustment connection mechanism is respectively provided with a mounting plate and a cleaning plate. The mounting plate is provided with a crawler-type walking mechanism, and the cleaning plate is evenly provided with cleaning brush hairs; the rotation adjustment mechanism includes a support limiting plate, a fixed side plate, a rotation motor, and a matching structure.

[0004] In the above application document, a driving motor drives a gear to rotate, the gear drives a first rack plate and a second rack plate to approach or move away from each other, and then drives a first movable plate and a second movable plate to move relative to the first support rod and the second support rod, so that a second adjusting rod rotates, and the second adjusting rod drives a first adjusting rod to rotate. Under the limitation of a limiting connecting rod, the mounting plate and the cleaning plate approach the inner wall of the pipeline, and the crawler-type walking mechanism and the cleaning brush hairs are simultaneously attached to the inner wall of the pipeline. The rotation motor drives the fixed side plate, the support limiting plate, and the second support rod to rotate as a whole, thereby driving the adjustment connection mechanism and the cleaning plate to rotate, and the cleaning plate drives the cleaning brush hairs to rotate to clean the inner wall of the pipeline. The overall cleaning effect is poor, and it is easy to have an incomplete cleaning situation only by driving the cleaning brush hairs to rotate by the cleaning plate. Therefore, it needs to be improved. Summary of the Invention

A waterproof cover 143 is fixedly connected to the side of the moving seat 141. A flushing mechanism 16 is arranged on the top of the waterproof cover 143. When the threaded rod A4 rotates, it will drive the moving seat 141 to move horizontally through the cooperation between the threads. When the threaded rod B8 rotates, it will drive the telescopic rod 7 to move out of the telescopic cylinder 6 through the cooperation between the threads. The rotating motor 142 is fixedly connected to a rotating shaft 144 through its output shaft. A slider 145 is fixedly connected to the surface of the rotating shaft 144. The moving cylinder 1413 is fixedly connected to one end of the rotating cylinder 5 away from the cross bar 10. A chute 147 is opened on the inner wall of the moving cylinder 1413. A return spring 146 is fixedly connected to the inner side wall of the moving cylinder 1413. An eccentric ring 148 is fixedly connected to the surface of the rotating shaft 144. An annular groove A149 is opened at one end of the moving cylinder 1413 away from the rotating cylinder 5. An air pressure chamber 1410 is fixedly connected to the side of the rotating motor 142. An airbag 1411 is arranged at one end of the air pressure chamber 1410. A piston rod A1412 is slidably connected to the inside of the other end of the air pressure chamber 1410.

When the rotating shaft 144 rotates, it will drive the moving cylinder 1413 to rotate synchronously through the cooperation between the slider 145 and the chute 147. When the airbag 1411 is squeezed, the air pressure inside it will enter the air pressure chamber 1410 and push the piston rod A1412 to move to the right. The piston rod A1412 moving to the right will drive the moving cylinder 1413 to move to the right, and the return spring 146 will be stretched. A lubricating component 15 is arranged at the bottom of the eccentric ring 148. The lubricating component 15 includes an oil storage tank 151.

A fuel injection pipe 155 penetrates and is fixedly connected to the side of the oil storage tank 151.;

[0033] During use, manually rotate the rotating block 12 to drive the cross bar 10 to rotate. The rotation of the cross bar 10 drives the bevel gear B 11 to rotate. The rotation of the bevel gear B 11 drives the bevel gear A 9 to rotate. The rotation of the bevel gear A 9 drives the threaded rod B 8 to rotate. When the threaded rod B 8 rotates, it drives the telescopic rod 7 to move out of the telescopic cylinder 6 through the cooperation between the threads, thereby adjusting the distance that the cleaning brush 13 extends. Place the pipeline to be cleaned on the right side of the overall device through the pipeline support. Turn on the moving motor 3 to drive the threaded rod A 4 to rotate. When the threaded rod A 4 rotates, it drives the moving seat 141 to move horizontally through the cooperation between the threads, so that the cleaning brush 13 completely enters the pipeline interior and contacts the pipeline inner wall. Turn on the rotating motor 142 to drive the rotating shaft 144 to rotate. The rotation of the rotating shaft 144 drives the moving cylinder 1413 to rotate synchronously through the cooperation between the slider 145 and the chute 147. The rotation of the moving cylinder 1413 drives the rotating cylinder 5 and the cleaning brush 13 to rotate. When the eccentric ring 148 rotates with the rotating shaft 144, it will repeatedly squeeze the airbag 1411. When the airbag 1411 is squeezed, the air pressure inside it will enter the air pressure chamber 1410 and push the piston rod A 1412 to move to the right. The rightward movement of the piston rod A 1412 drives the moving cylinder 1413 during rotation to move to the right. The rightward movement of the moving cylinder 1413 drives the rotating cylinder 5 and the cleaning brush 13 to move to the right, and the return spring 146 will be stretched. When the eccentric ring 148 leaves the airbag 1411, the return spring 146 rebounds to drive the moving cylinder 1413, the rotating cylinder 5, the cleaning brush 13, and the piston rod A 1412 to move to the left to restore the original state, and the airbag 1411 expands again. By rotating the rotating cylinder 5 and the cleaning brush 13 while repeatedly moving left and right, the inner wall of the pipeline is cleaned, improving the cleaning effect and preventing incomplete cleaning. During the process of the eccentric ring 148 squeezing the airbag 1411, when the surface of the airbag 1411 is dry and rough, it will drive the pulley 153 to rotate through friction. The rotation of the pulley 153 will bring out a part of the lubricating oil in the oil storage tank 151 through the oil pits 154 on its surface and smear it on the airbag 1411 when it contacts the airbag 1411. By maintaining a small amount of lubricating oil each time, the surface of the airbag 1411 is lubricated, thereby reducing the wear on the airbag 1411.
