Regulating storage tank inflow control device for rainwater collection and waterlogging prevention

Abstract

The invention provides a regulating storage tank inflow control device for rainwater collection and waterlogging prevention. The device comprises a case, and a dam which crosses the internal portion of the case, a water inlet pipe, a water outlet pipe, and at least one collection pipe which are arranged on the case. The internal space of the case is divided into a buffer room and a collection room by the dam. A collection opening communicated with the buffer room and the collection room is formed in the dam. Moreover, a switch device arranged on the collection opening controls the collection opening to be opened or closed. The water inlet pipe makes the buffer room and an external water inlet pipeline communicated, the water outlet pipe makes the buffer room and the external water outlet pipeline communicated, and the collection pipe makes the collection room and the regulating storage tank communicated. The regulating storage tank inflow control device for the rainwater collection and the waterlogging prevention is simple in structure and can further be suitable for existing various types of regulating storage tanks, can not only collect clean rainwater when rainstorm warning is not received, but also effectively prevent waterlogging when the rainstorm warning is received.

Description

technical field [0001] The invention relates to the field of urban drainage, in particular to a water inlet control device for a storage tank used for collecting rainwater and preventing waterlogging. Background technique [0002] With global warming, extreme weather is becoming more and more frequent, and extreme rainfall tends to be more or more intense. Today, with the rapid development of cities, the ability of the surface to absorb and retain rainwater has been greatly weakened. On the one hand, it is not conducive to retaining surface water when the rainfall is low, and it is easy to cause drought; on the other hand, when the rainfall is large, the existing urban drainage system It causes huge pressure, and it is very easy to cause waterlogging due to the accumulation of water on the ground. Since rebuilding a new type of urban drainage system or large-scale renovation of the existing urban drainage system is costly and almost impractical, governments around the world...

AI Technical Summary

Problems solved by technology

However, the function of rainwater collection requires rainwater to flow into the storage tank under different rainfall conditions; while the function of placing waterlogging only needs to discharge excess rainwater beyond the processing capacity of the urban drainage system into the storage tank, otherwise once the storage tank If it is fully occupied by the rainwater in the early stage of heavy rainfall, it will no longer be able to solve the problem of waterlogging in the later stage of heavy rainfall

The existing storage tank is connected to the drainage system in various parts of the city through various pipelines, making it difficult to achieve flexible control of water inflow
