[0002] In the existing municipal sewage system, sewage pipes play a vital role, which are responsible for collecting and transporting sewage generated in the city. However, with the rapid development of urbanization, the increase in sewage volume and the complexity of sewage composition have put forward higher requirements for the cleaning and maintenance of sewage pipes. The traditional municipal sewage pipe design usually only includes simple collection and transportation functions, and lacks an effective automatic cleaning mechanism.

[0003] In existing municipal sewage pipes, due to long-term erosion and accumulation of solid particles, grease, fiber and other impurities in sewage, a thick layer of dirt often forms on the inner wall of the pipe. These dirt will not only reduce the sewage discharge efficiency of the pipe and increase the risk of blockage, but also corrode the pipe material and shorten the service life of the pipe. In order to remove these dirt, manual cleaning or high-pressure water gun cleaning is usually required, but these methods have problems such as high labor intensity, low efficiency, and incomplete cleaning.

[0022] Sewage discharge process: When sewage flows into the pipeline, the water flow impacts the filter plate 2, and most of the stains are intercepted by the filter plate 2. At the same time, the impact of the water flow causes the filter plate 2 and the sliding ring 3 to slide in the inner tube 1, and the sliding ring 3 cleans the inner wall of the inner tube 1. Cleaning process: When the water flow stops, the contraction spring 6 pulls the filter plate 2 and the sliding ring 3 back to the initial position through the connecting rope 4, waiting for the next sewage discharge and cleaning process. A dredging member is also provided on the inner wall of the inner tube 1, including a mounting frame 10 installed on the inner wall of the inner tube 1, a fixing column 11 is installed at the bottom of the mounting frame 10, and a needle plate 12 is installed at the bottom of the fixing column 11.

[0023] Embodiment 2:

[0024] See also Figure 1-3, a municipal sewage pipe with a cleaning function, the pipe mainly includes an inner tube 1 and an outer tube 5. A filter plate 2 is arranged inside the inner tube 1, and a sliding ring 3 is installed on the surface of the filter plate 2. The sliding ring 3 contacts the inner wall of the inner tube 1 and is used to clean the stains on the inner wall. The bottom of the sliding ring 3 is connected to the contraction spring 6 through a connecting rope 4, and the contraction spring 6 is arranged in the cavity between the outer tube 5 and the inner tube 1. A connecting piece 1 7 is installed on the surface of the inner tube 1, and a connecting piece 2 8 is installed at the connection between the connecting rope 4 and the contraction spring 6.
