Description
Technical Field
[0001] The utility model relates to the technical field of municipal drainage, in particular to a rainwater inlet filtering device. Background Art
[0002] Municipal road pavement drainage is an important part of municipal engineering. On the one hand, water accumulation on the road will hinder the passage of the road, causing vehicles to slip on the road surface and affecting traffic safety; on the other hand, long-term water accumulation on the road surface will reduce the strength of the roadbed soil and cause overall damage to the roadbed and pavement. Usually, rainwater outlets are preset on both sides of municipal roads to increase the drainage speed of the road on rainy days. These rainwater outlets are collected in the same pipeline underground and discharged uniformly. Since the drainage efficiency of the road will be affected once the underground pipeline is blocked, it is necessary to install a filtering device in the rainwater outlet to filter the incoming rainwater to prevent garbage, stones, mud and sand mixed in the rainwater from blocking the underground pipeline.
[0003] According to Chinese patent application No. 202223311244.0, a rainwater inlet filter device is disclosed, including a placing rack, a card slot seat is arranged in the middle part of the placing rack, and a positioning assembly is installed in the inner cavity of the card slot seat, and a filter assembly is arranged at the middle and upper end of the positioning assembly and the placing rack; the filter assembly includes a filter frame, a buckle rod and a wellhead mesh plate, the filter frame is arranged at the middle and upper end of the positioning assembly and the placing rack, and the four corners of the top end of the filter frame are connected with the buckle rods, and the top end of the buckle rod is connected with the wellhead mesh plate; an anti-slip layer is arranged on the outer surface of the filter assembly, and by providing the filter assembly, dirt brought by rainwater can be filtered, and impurities can be filtered in the filter frame. It only needs to clean the filter frame regularly, which can effectively prevent the wellhead mesh plate from being blocked. The wellhead is covered by the wellhead mesh plate at the top of the filter frame, which will not hinder the use of the road, and rainwater directly enters the drainage through the aperture of the wellhead mesh plate.
[0004] In the prior art, fallen leaves on the road are common debris on the ground in cities, and are easily washed into the stormwater inlets by rainwater. The filter needs to filter debris such as mud and gravel, and the fallen leaves accumulate on the filter in the stormwater inlet. Since the fallen leaves have a larger overall area than gravel and mud, they are more likely to cause the filter to be blocked. When the drainage volume of municipal roads is large, the drainage effect of the filtering device is reduced. Therefore, we propose a stormwater inlet filtering device to solve the above problems.
