Description

Technical Field

[0001] The utility model relates to the technical field of conduit cleaning, in particular to a device for cleaning a water conservancy conduit in a water conservancy project. Background Art

[0002] Water conservancy projects require the construction of dams, dikes, spillways, water gates, water inlets, channels, ferries, rafts and fishways, etc., different types of hydraulic structures to achieve their goals. The operation pipelines of water conservancy projects are indispensable. Water conservancy conduits are mainly used to transport water. After long-term use, a large amount of dirt will adhere to the inner wall of the conduit, which will directly affect the effect of water transportation for a long time. Therefore, it is necessary to regularly use cleaning equipment to clean the inside of the water conservancy conduit.

[0003] Traditional pipe cleaning devices mainly rotate the cleaning head to drive the cleaning bristles on it to clean the inner wall of the pipe to remove dirt on the inner wall of the pipe. However, traditional pipe cleaning devices are difficult to adapt to pipes of different diameters and can only clean pipes with the same inner diameter. If pipes with other inner diameters need to be cleaned, cleaning heads of different sizes need to be replaced, which is time-consuming and labor-intensive. At the same time, preparing cleaning heads of different sizes increases cost investment. Utility Model Content

It has high versatility and is convenient and quick to adjust. Compared with traditional technologies, there is no need to replace cleaning heads of different sizes to clean catheters with different inner diameters, and there is no need to equip multiple cleaning heads of different sizes, thereby reducing cost investment.

[0008] Furthermore, the adjustment mechanism includes an adjusting screw and a twist handle. The end surface of the circular seat is provided with a threaded hole that penetrates the inner guide hole. The adjusting screw thread is matched and installed in the threaded hole. One end of the adjusting screw extends into the inner guide hole and is rotatably connected to the main piston. The other end of the adjusting screw extends to the outside of the circular seat and is installed with a twist handle.

[0012] Furthermore, the cross section of the guide groove is rectangular, and the cross section of the extension rod is rectangular matching the guide groove.

[0013] Furthermore, a second driving mechanism is provided on the mounting plate, and the second driving mechanism is used to drive the rotating shaft to rotate and adjust.

The utility model has high versatility and convenient and quick adjustment. Compared with traditional technologies, there is no need to replace cleaning heads of different sizes to clean conduits with different inner diameters, and there is no need to equip multiple cleaning heads of different sizes, thereby reducing cost investment.

[0028] When the cleaning device is used to clean the hydraulic conduit, the circular seat 1 is placed inside the hydraulic conduit, and the inner wall of the hydraulic conduit can be scraped and cleaned by the bristles 17 to remove dirt on the inner wall of the tube. The main piston 13 can be driven to translate left and right in the inner guide hole 11 by operating the adjustment mechanism 2. When the main piston 13 moves toward the side of the branch hole 12, the air in the inner guide hole 11 can be compressed, thereby pushing the auxiliary piston 14 to move toward the periphery.

The device has high versatility and convenient and quick adjustment. Compared with the traditional technology, it is not necessary to clean conduits with different inner diameters by replacing cleaning heads of different sizes, and it is not necessary to equip multiple cleaning heads of different sizes, thereby reducing cost investment.

[0029] Specifically, the adjustment mechanism 2 includes an adjusting screw 21 and a twist handle 22.
