Description

Technical Field

[0001] The utility model relates to the technical field of road drainage, in particular to a filtering device for an urban drainage system. Background Art

[0002] The urban drainage system is an engineering facility system for treating and removing urban sewage and rainwater, and is an integral part of urban public facilities. The urban drainage system planning is an integral part of the city's overall planning. The urban drainage system is usually composed of drainage pipes and sewage treatment plants; in the case of sewage and rainwater diversion, sewage is collected by drainage pipes, sent to sewage treatment, and then discharged into water bodies or recycled; rainwater runoff is collected by drainage pipes and discharged into nearby water bodies.

[0003] On rainy days, mud, leaves and other debris on the road will be brought into the underground drainage pipes. If they are not cleaned for a long time, they will cause blockage, which will not only reduce the drainage volume but also cause water accumulation on the road. Patent number 202320382647 is a road drainage filter device. By adopting a telescopic structure, the length of the filter pair can be adjusted according to the depth of the drainage channel, so as to maximize the capacity of filtering debris.

[0004] During actual use, the filter net will also have a reduced drainage capacity due to blockage by debris. If there is heavy rain, the water on the road cannot be drained quickly, resulting in serious waterlogging on the road. Therefore, a new type of filtering device is needed that can not only filter out debris but also does not affect the drainage function. Utility Model Content

[0005] The utility model is to solve the technical problems mentioned in the above background technology, and proposes the following technical solutions:

[0010] Preferably, a fixing plate is provided at the bottom of the partition, and third baffles are provided on the left and right sides of the fixing plate respectively.

[0011] The beneficial effects of the utility model are:

[0012] 1. A filter barrel is provided, a partition is provided in the filter barrel, a square groove is provided on the partition, and a third water outlet hole and a fourth water outlet hole are provided on the side wall of the filter barrel, the third water outlet hole and the fourth water outlet hole are respectively located on the upper and lower sides of the partition. When water flows into the filter barrel, debris will fall under the partition through the square groove on the partition, and then be filtered by the filter net so that the debris will be blocked in the filter barrel to prevent the debris from entering the drainage system and causing blockage. When the water level in the filter barrel is higher than the third water outlet hole, the water will flow out from the third water outlet hole, avoiding the problem of waterlogging on the road due to reduced drainage in heavy rain.

[0013] 2. By setting the first baffle on the inner wall of the filter barrel, it can be prevented that when the water flow is too large, the debris will flow out directly through the third water outlet, causing the drainage system to be blocked.

[0014] 3. By setting a second baffle and a fixed plate at the bottom, it can prevent the debris that falls under the baffle from flowing into the top of the baffle from the square groove on the baffle as the water level rises, and finally flowing out from the third water outlet, causing the drainage system to be blocked.
