Description

Gutter inlet filtering device

Technical Field

The utility model relates to the technical field of inlet for stom water filtration, in particular to an inlet for stom water filtration device.

Background

The inlet for rain water is the inlet for ground rainwater to enter the rain water pipeline. The traditional rainwater drainage mode is that ground rainwater is directly drained into a rainwater pipeline through a rainwater inlet, gaps of a rainwater grate on the rainwater inlet are relatively large, larger pollutants such as leaves and branches can be intercepted, smaller pollutants enter the rainwater pipeline through the rainwater inlet, and the smaller pollutants enter landscape water bodies such as city rivers and lakes and are discharged into the landscape water bodies after entering the rainwater pipeline, so that water environment pollution of the landscape water bodies is caused. In order to improve the water quality of the rainwater pipeline, on the premise of ensuring the rainwater overflow capacity of the rainwater inlet, a matched filtering device is arranged under the rain grate of the rainwater inlet.

For example, chinese patent application No. CN201020149294.1, a gully filter device is located below the rain grate of the gully, the shape of the upper opening of the gully filter device is adapted to the shape of the rain grate, the gully filter device is a quadrangular frustum pyramid structure with a large upper opening and a small lower bottom, the lower bottom of the gully filter device is closed, and circular filter holes are formed on the peripheral side walls of the gully filter device.

But when in actual use, the device can not carry out multistage filtration to silt and the impurity of different volumes in the rainwater, can only filter bulky impurity, causes silt and small impurity to block up the pipeline, and simultaneously in the jam process, the rivers that overflow can't discharge, cause the road surface ponding easily.
