[0002] In my country, municipal facilities refer to various buildings, structures, equipment, etc. that are set up within the scope of urban area and town planning and construction, and provide paid or free public products and services to residents based on government responsibilities and obligations. The construction of various public infrastructure supporting urban life belongs to the category of municipal engineering, such as common urban roads, bridges, subways, various pipelines closely related to life: rainwater, sewage, water supply, recycled water, electricity, telecommunications, heat, gas, etc., as well as the construction of squares, urban greening, etc., all belong to the category of municipal engineering. The existing drainage pipes need to bee the pump connection when draining water.

[0003] However, the existing sealing structure at the pump of the water supply and drainage pipeline has the following disadvantages:

[0004] (1) The sealing structure of the existing water supply and drainage pipeline pump has a weak fixed sealing function. When in use, the pump connection needs to stop and drain the flow in the pipeline. The pressure at the connection is relatively high, and water will seep out from the connection, which is likely to cause water waste and water pollution;

[0005] (2) The sealing structure at the pump of the existing water supply and drainage pipeline has a weak auxiliary fixing function. When in use, the pump connection cannot solve the problem of liquid flowing out of the gap by simply fixing the sealing structure. The existing technology only relies on threaded connection and cannot seal the connection. Utility Model Content
