Simple rainwater filter device suspended on dandruff comb

Abstract

The invention relates to a rainwater filter device, in particular to a simple rainwater filter device suspended at the bottom of a dandruff comb and convenient for removing dirt. The simple rainwater filter device suspended on the dandruff comb comprises the dandruff comb, wherein a water collection bucket having a certain distance from the lower end surface of the dandruff comb is suspended at the lower end part of the dandruff comb through two or more suspension ropes; the water collection bucket comprises an outer wall and a bottom surface as well as a filter net erected in a manner of forming a certain angle with the bottom surface; a water discharge plate with a plurality of through holes in the bottom surface and a filter layer filled with a filter material are fixed at the bottom of the water collection bucket; a plurality of through holes are formed in each of the bottom surface of the water collection bucket and the filter net; and the bottom surface of the water collection bucket and the lower section of the filter net are surrounded by the side walls of the filter layer. According to the device, sandy soil and floating objects can be filtered out for preventing a water collection well from losing the function of the water collection well; and when the floating objects accumulated due to a reason such as long-term use, increased rainfall or the like exceed the height of the filter net, rainwater is discharged through a space between the filter net and a flow guide plate, so that the problem that the water collection well loses the function due to blockage of the filter net can be prevented.

Description

technical field [0001] The invention relates to a rainwater filtering device, and more specifically, relates to a simple rainwater filtering device suspended at the bottom of a grate for easy removal of dirt. Background technique [0002] The rainwater outlet (streetinlet) is installed at a certain interval on the side of the road, and it is a concrete structure connected to the main pipe through a branch pipe. These gullies discharge rainwater collected from roads, residential areas, etc. to the sewer main. [0003] figure 1 It shows well-known gutter and water collection well structure, and the bottom of the water collection well (1) has a space for storing sand and soil, and a drainpipe (2) is arranged on the side. The upper end of the water collection well (1) is usually a grate (10) made of stainless steel, and sand or various floating objects etc. pass through the grate (10) and accumulate inside after rainfall. [0004] In addition, due to structural reasons, the p...

AI Technical Summary

Problems solved by technology

[0004] In addition, due to structural reasons, the problem of the above-mentioned water collection wells is that the drainage outlet is often blocked by accumulations, and it is difficult to distinguish the amount of accumulations visually. The clogging of the drainage outlet results in the loss of the function of the drainage outlet and the occurrence of sewage backflow. , before maintenance

[0006] However, the existing technology still does not solve the problems that existed in the past. It is impossible to visually confirm whether the filter screen is filled with accumulations without opening the grate. Maintenance is performed only after the filter screen is blocked and rainwater is poured back.

[0007] Not only that, the rainwater is only discharged through the filter, and the water quality of the rainwater has not been improved in any way
