Road rainwater filtering device

Abstract

The invention discloses a road rainwater filtering device. The road rainwater filtering device comprises a filtering cover plate, a filtering frame and a supporting frame, wherein the filtering coverplate is positioned above the filtering frame; first filtering wide grooves are uniformly arranged on the surface of the filtering cover plate; a clamping groove is arranged on a rear end face of thefiltering cover plate; vertical rods are uniformly arranged at the left and right sides of the filtering frame; second filtering wide grooves are uniformly arranged on the bottom surface of the filtering frame; limiting sliding blocks are arranged at the left and right sides of the rear end of the bottom surface of the filtering frame; limiting plates are arranged on the front and rear end faces of the filtering frame; the supporting frame comprises a supporting bottom plate, a supporting side plate and a sliding rail; a clamping plate is arranged on the supporting side plate; and the clampingplate is matched with the clamping groove. The road rainwater filtering device disclosed by the invention has a firm whole structure and can resist the impact of rainwater; the post-period maintenance cost is reduced; meanwhile, relatively large impurities in the rainwater are removed through the filtering cover plate and then the filtering cover plate is used for further filtering and removing the impurities, so that the rainwater filtering effect is improved; and the road rainwater filtering device is compact and reasonable in design, is convenient to mount and dismount and is convenient for recycling the impurities at a later period.

Description

technical field [0001] The invention specifically relates to a road rainwater filtering device. Background technique [0002] Rainwater treatment is the purification process of surface runoff water (rainwater, snowmelt water, sprinkler water) in urban areas. Depending on the drainage system of the pipeline system (separation system or combined system), rainwater treatment can be treated alone or combined with domestic sewage and industrial wastewater. The water volume of rainwater treatment is calculated according to the rainwater channel (calculated according to the dilution factor or the water volume of the rainwater pumping station), but it is advisable to set up a rainwater adjustment tank before entering the treatment structure. The quality of rainwater in different regions is different, and the treatment methods are also different. When treating road rainwater, since the road surface will contain a large amount of garbage, fallen leaves, etc., it will enter the pipel...

AI Technical Summary

Problems solved by technology

However, when there is a heavy rainstorm, due to the strong impact of rainwater, the surface of the filter bag will be damaged, which will affect the actual filtering effect.

Moreover, due to the small volume inside the filter bag, it is necessary to timely recycle the internal garbage, which will increase the labor cost in the later stage.
