Energy-saving overflow control mechanism for municipal storm drainage

Abstract

The invention discloses an energy-saving overflow control mechanism for municipal storm drainage. The energy-saving overflow control mechanism comprises a drainage seat, a drainage cavity and an overflow cavity are formed inside the drainage seat, a water inlet and a water outlet are formed in the front side wall and the rear side wall of the drainage cavity respectively, an overflow drainage pipeis arranged on the inner wall of the overflow cavity in a penetrating mode, a communicating pipe is further arranged between the drainage cavity and the overflow cavity in a penetrating mode, a fixing block and an annular sliding seat are fixedly connected to the inner top wall of the overflow cavity, a pipe plug used in cooperation with the communicating pipe is connected inside the annular sliding seat in a sliding mode, and the end, located in the overflow cavity, of the communicating pipe is plugged by the pipe plug, and a reset spring is connected between the back face of the pipe plug and the fixing block. The energy-saving overflow control mechanism has the advantages that the overflow cavity and the overflow drainage pipe can be automatically opened in time for storm drainage without manual or electric drive control, so that manpower and electric power are saved, and the problem of urban inland inundation can be effectively solved in time.

Description

technical field [0001] The invention relates to the technical field of municipal drainage, in particular to an energy-saving overflow control mechanism for municipal drainage. Background technique [0002] In recent years, urban waterlogging has become more common across the country. The flooding of the city was caused by heavy rain and waterlogging. A large amount of rainfall in a short period of time caused the paralysis of the municipal drainage system. Nowadays, under most normal drought conditions, the combined sewage flows into the downstream sewage treatment plant through the municipal drainage network for treatment; when there is heavy rain, the downstream sewage treatment plant can only receive a certain amount of sewage, causing the municipal The water level of the drainage pipe network continues to rise. At this time, the overflow drain pipe in the municipal drainage pipe network can be opened, so that the water can be discharged to the surrounding spare receivin...

AI Technical Summary

Problems solved by technology

However, the overflow drainage pipes of the existing municipal drainage pipe network generally need to be opened manually or controlled by electric drive, which not only consumes a lot of manpower and power, but also often makes it difficult to judge the best opening time and is inconvenient to use.
