A sponge city water storage pipeline anti-clogging structure

Abstract

The invention provides an anti-blocking structure of a water storage pipeline in a sponge city, belonging to the technical field of pipeline drainage, comprising a water delivery pipe, the lower surface of the water delivery pipe is fixedly connected with a dredging pipeline, the top of the dredging pipeline is nested with a shunt pipe, and the inside of the dredging pipeline is slidably connected There is an inner sliding sleeve, and the inner rotation of the dredging pipeline is connected with a central axis rod. The anti-clogging structure of the sponge city water storage pipeline is equipped with water wheel blades, and the water flow impacts on the surface of the water wheel blades through gravity under the guidance of the guide plate, so that the water wheel blades rotate under the impact of the water flow, and drive the rotating rod to rotate , the synchronous rotation of the rotating rod drives the cleaning rod to swing, and further makes the bristles continuously scrub the lower surface of the filter layer, the upper surface of the grille layer and the inner bottom of the inner sliding sleeve to realize the cleaning of impurities in the above three places. Effectively prevent sludge from depositing on the filter layer and the inner bottom of the inner sliding sleeve, greatly reducing the possibility of silting of the device itself.

Description

technical field [0001] The invention relates to the technical field of pipeline drainage, in particular to a pipeline anti-blocking structure. Background technique [0002] Sponge city is a new generation of urban stormwater management concept. It means that the city can be like a sponge, and has good elasticity in adapting to environmental changes and dealing with natural disasters caused by rainwater. It can also be called "water elastic city". The international general term is "low-impact development rainwater system construction", which absorbs, stores, infiltrates, purifies water when it rains, and releases and utilizes the stored water when needed, so as to realize the free migration of rainwater in the city and from the ecosystem. Starting from services, constructing water ecological infrastructure across scales and combining various types of specific technologies to build water ecological infrastructure is the core of the sponge city. [0003] Among them, the applic...

Problems solved by technology

[0003] Among them, the application number is CN201911213012.1, a sponge city rainwater decontamination, diversion and anti-blocking device, which can divert the rainwater by setting the drainage main pipe and the shunt pipe; slow down the pressure of the main pipe during drainage, and prevent the pipe from bursting when the flow rate is too large , and the drainage flow of the drainage main pipe can be detected by the detection device. When the drainage flow increases or the outlet flow decreases, the water flow increases or the filter screen is blocked, that is, the water flow is controlled to enter the shunt pipe. The filter screen anti-blocking device is driven by the water flow in the shunt pipe to clean the blocked filter screen in the main drainage pipe, but the anti-blocking structure described in this technical solution uses electric drive and detection to realize the anti-blocking cleaning of the filter screen. Once the power is disconnected, this technical solution cannot realize the detection and cleaning of the anti-blocking, and it is easy to occur that the silt cannot be automatically cleaned. In particular, once the silt is blocked inside the anti-blocking structure, the device itself cannot self-cleaning
