Description
Technical Field
[0001] The utility model relates to the technical field of preventing pipeline blockage, in particular to a diversion device for mixed drainage of underground rainwater and sewage. Background Art
[0002] The mixed discharge and diversion of underground rainwater and sewage is an important environmental issue, which involves the design and operation of urban drainage systems. Mixed discharge refers to the mixed flow of rainwater and sewage in pipes, while diversion refers to the collection and treatment of rainwater and sewage separately. Due to historical reasons or design defects, rainwater and sewage pipes may be connected or intersected, resulting in the mixing of the two. This mixed discharge not only increases the difficulty and cost of sewage treatment, but may also pollute the environment and affect the quality of life of residents. Rainwater and sewage diversion is a drainage system that separates rainwater and sewage, transports them through different pipes for discharge or subsequent treatment. Rainwater can be discharged directly into natural water bodies through rainwater pipes, while sewage needs to be collected through sewage pipes and sent to sewage treatment plants for treatment.
[0003] A water conservancy anti-blocking pipe with a public number of CN218643298U, the technical solution of which is as follows: comprising a water conservancy pipe body, the inner circular wall surface of which is fixedly mounted two fixed blocks; an anti-blocking component, which is arranged on the inner circular wall surface of the water conservancy pipe body and is used to prevent the water conservancy pipe body from being blocked, and the water conservancy pipe body, the water impeller, the connecting roller and the blocking column cooperate with each other so that the blocking column blocks the aquatic plants, and the clamping block, the fixing groove, the mounting block and the third spring cooperate with each other so that the clamping block enters the interior of the fixing groove, and the water conservancy pipe body, the water impeller, the connecting roller and the blocking column cooperate with each other so that the water conservancy pipe body, the water impeller, the connecting roller and the blocking column can block the aquatic plants, and ... The movable plate, movable ring, second spring, mounting block, fixed block, connecting hole and mounting column cooperate with each other to move the mounting block to the outside of the fixed connecting hole, thereby taking out the water impeller, connecting roller and blocking column and cleaning the aquatic plants on the blocking column to prevent the water conservancy pipeline body from being blocked, thereby achieving the effect of preventing the water conservancy pipeline body from being blocked. In this scheme, some larger sediments are mixed in the discharge of sewage and rainwater, and the larger sediments cannot be processed. The pipeline will be blocked for a long time, thereby affecting the normal use of the pipeline. For this reason, we propose a diversion device for mixed discharge of underground rainwater and sewage.
