Description

TECHNICAL FIELD

[0001] The utility model relates to drainage pipeline technical field, concretely is a drainage pipeline automatic flushing device. BACKGROUND

[0002] In the past, when designing and constructing urban underground drainage pipelines, in order to prevent urban areas from causing sewage overflow and waterlogging due to insufficient pipeline capacity, the diameter of the pipeline is determined according to the instantaneous maximum value of the drainage volume required by the pipeline. In this way, when the design instantaneous maximum value of the flow does not occur, the water volume inside the pipeline will be relatively small, which will cause the water flow speed inside the pipeline to fail to reach the design value, and the silt and pollutants in the sewage will be deposited inside the pipeline, causing sedimentation. Especially in combined drainage pipelines that discharge rainwater and sewage together, due to the small water volume on sunny days, it is easy to cause the accumulation of pollutants inside the pipeline, forming an obstruction inside the pipeline, and causing the sewage inside the pipeline to ferment and emit odors. At the same time, the pollutants accumulated in the combined drainage pipeline on sunny days will be directly discharged into public water areas such as rivers and lakes during rainy days, causing pollution to the rivers and affecting the sanitation of public water areas;

The hinge of the water baffle is arranged above the frame, and the water baffle is provided with a floating box.

Without interfering with the water flow, it can accumulate more potential energy, improve the impact force when closing the door, ensure the stability of closing the door, and improve the practicality of the present application;
