Technical Field

The invention relates to the technical field of relevant municipal equipment in sponge cities, in particular to a road drainage device for a sponge city.

Background

The sponge city can absorb, store, seep water and purify water when raining, and release and utilize the stored water when needed, so that the city can adapt to environmental changes and respond to natural disasters caused by rainwater.

Because other pollutants such as rubbish on the urban road are more, when rainy season, especially under the torrential rain weather, the rainwater that falls on the earth's surface can wash away these pollutants and take away and get into urban internal drainage system, if directly arrange to the regional pollution of rivers then can lead to the fact the rivers, still can lead to water resource to run off and cause the waste, not conform to the design theory of sponge city, if all input municipal sewage treatment system and handle, then can greatly increased sewage treatment system's pressure. In view of this, this application document proposes a road drainage device for sponge city.

Disclosure of Invention

The invention aims to solve the defects in the prior art, and provides a road drainage device for a sponge city.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a road drainage device is used in sponge city, is including digging the drainage canal of establishing in the road both sides, the embedded trench cover that is equipped with of drainage canal, the road below still digs and is equipped with the circular recess, the circular recess passes through the inlet tube intercommunication with the drainage canal, sealed rotation is connected with the baffle in the circular recess, just the upper end of baffle adopts the iron material to make, the interior top of circular recess inlays and is equipped with the permanent magnet, be equipped with the conveyer pipe on the inner wall of circular recess, the interior bottom of circular recess is equipped with the delivery pipe, just the pipe diameter of inlet tube is greater than the pipe diameter of delivery pipe and is less than the pipe diameter of conveyer pipe, the upper end fixedly connected with of conveyer pipe and the intake pipe of its inside intercommunication, just the inlet end.

Preferably, a limiting rod is embedded in the air inlet pipe, a sealing plug is connected in the air inlet pipe in a sealing and sliding mode and is elastically connected to the limiting rod through a spring, an air groove is formed in the side wall of the sealing plug, and a strip-shaped groove is formed in the inner wall of the air inlet pipe.

The invention has the following beneficial effects:

1. by arranging the circular groove, the conveying pipe and the discharging pipe, rainwater can be collected, and meanwhile, the conveying pipe and the discharging pipe can respectively treat rainwater in different periods, so that not only is waste caused by rainwater loss avoided, but also pollution caused by surface pollutants flowing into a municipal water supply system or a river area along with rainwater is avoided;

2. through the arrangement of the air inlet pipe, when rainwater cached in the circular groove is discharged after raining, pressure difference is generated in the air inlet pipe due to flow speed difference, dust-containing air on the ground surface can be sucked into the air inlet pipe and discharged along with the rainwater, and therefore air near a road can be purified;

3. through setting up parts such as sealing plug, spring and gag lever post, can not bleed when the intake pipe is not bled, the spring pushes up the sealing plug and plugs up the inlet end of intake pipe to prevent debris on the road surface from blockking up the intake pipe, keep the intake pipe to use for a long time.
