Multifunctional turnover type blocking and discharging flood prevention device

Abstract

The device comprises a multifunctional storage tank which is an underground tank arranged between ramp entrance retaining walls, one end of the bottom surface of the multifunctional storage tank is a storage platform, the other end of the bottom surface of the multifunctional storage tank sinks to form a water collecting tank, an overflow guide drainage slope is transversely arranged between the storage platform and the water collecting tank, and a pumping and draining pump is arranged in the water collecting tank; the rainwater grate plate is a steel plate arranged at the top of the multifunctional storage tank, one end of the rainwater grate plate is hinged to the side, away from the underground space, of the multifunctional storage tank, and a plurality of rainwater through holes are transversely formed in the other end of the rainwater grate plate side by side; the rainwater grate plate is provided with a first position covering the top of the multifunctional storage tank and a second position opened at the top of the multifunctional storage tank and perpendicular to the ground. The device is simple in structure and convenient to use, has the functions of flood prevention material storage, emergency accumulated water pumping and drainage and underground space backflow prevention, can greatly reduce the probability that the urban underground space is submerged, improves the safety coefficient of the underground space, and reduces the property loss of citizens.

Description

technical field [0001] The invention relates to the technical field of municipal drainage equipment, in particular to a multifunctional overturning drainage flood prevention device. Background technique [0002] With the destruction of the ecological environment and the intensification of global warming, the frequency of extreme weather is gradually increasing, and extreme rainstorm weather is one of them. In recent years, short-duration heavy rainfall has occurred frequently, far exceeding the city's conventional flood control and drainage fortification standards. Urban waterlogging ensues, and the urban underground space is the first to be harmed. Although the entrance and exit of the underground space have been fortified according to the standard and the ground elevation of the entrance has been raised, in the face of severe waterlogging caused by excessive rainwater, once the waterlogging exceeds the ground elevation of the entrance and exit of the underground space, it ...

AI Technical Summary

Problems solved by technology

Although the entrance and exit of the underground space have been fortified according to the standard and the ground elevation of the entrance has been raised, in the face of severe waterlogging caused by excessive rainwater, once the waterlogging exceeds the ground elevation of the entrance and exit of the underground space, it will directly flow back into the underground space, causing damage to municipal infrastructure and people’s property. Cause huge losses and directly threaten the lives of citizens in serious cases
