A rainwater filter device for sponge city

Abstract

The invention relates to the field of sponge urban rainwater filtering devices, in particular to a sponge urban rainwater filtering device which comprises a shell, a dredging mechanism, a covering andpressing mechanism, a filtering mechanism, a storing mechanism, a sealing mechanism, a sliding mechanism and a flood discharging mechanism. By connecting the shell with the dredging mechanism, the drainage and irrigation of a water source are facilitated; by clamping the covering and pressing mechanism on the top of the shell, the covering and pressing mechanism drives the filtering mechanism toshake under the effect of external force, and therefore debris, glass splinters, scrap iron and other harmful trash attached in the filtering mechanism can be easily blocked and recovered, the filtering mechanism keeps normally working, and pipeline blockage is prevented; and meanwhile, by arranging the storing mechanism on the side wall of the filtering mechanism, the debris, glass splinters, scrap iron and other harmful trash can be easily and better classified and recovered so as to be regularly disposed by workers, the stability of a drainage system is guaranteed, the rainwater dischargingamount can be promoted under the effect of the flood discharging mechanism, and the flood discharging and resisting effect is realized.

Description

technical field [0001] The invention relates to the field of rainwater filtering devices, in particular to a rainwater filtering device for sponge cities. 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". When it rains, absorb, store, infiltrate, and purify water, release and use the stored water when necessary, improve the function of the urban ecosystem and reduce the occurrence of urban flood disasters. During the process of collecting rainwater, there will be a large amount of Debris such as leaves, garbage, and sediment enter the waterway with the water flow, which will cause blockage of the drainage system and make the entire drainage system unable to operate normally.

[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". When it rains, absorb, store, infiltrate, and purify water, release and use the stored water when necessary, improve the function of the urban ecosystem and reduce the occurrence of urban flood disasters. During the process of collecting rainwater, there will be a large amount of Leaves, garbage, silt and other debris enter the waterway with the water flow, which will cause blockage of the drainage system and make the entire drainage system unable to operate normally

[0003] However, the traditional rainwater filtering device is relatively simple in filtering rainwater. When the rainwater in the pipeline contains harmful garbage such as glass and iron filings, it is very complicated to deal with after being filtered by the filter, and it is also inconvenient to filter. After the sundries and glass shards and other harmful wastes are effectively sorted and processed, if the staff is not careful when recycling the sundries, the hands will be scratched by the glass slag and iron filings in the sundries, resulting in Unnecessary harm, while the existence of harmful waste also destroys the ecological environment of the city
