Description

Technical Field

[0001] The utility model relates to the field of environmental engineering, in particular to a river pollution interception device. Background Art

[0002] At present, in the river management of water conservancy and environmental engineering, industry is gradually developing, population density is also gradually increasing, a large amount of industrial waste and domestic waste enters the river, the pollution of the river is gradually getting worse, the garbage and aquatic plants in the river are not cleaned up in time, and it is necessary to block the garbage in the river through trash racks to reduce the impact of garbage on the quality of river water and protect the ecological environment of the river.

[0003] After searching, Chinese patent announcement number: CN218712740U discloses a river pollution intercepting device, including a baffle and a supporting column supporting the baffle, a pollution cleaning structure and a storage structure. The baffle is provided with a plurality of through holes. The pollution cleaning structure is installed between two supporting columns and contacts with the baffle. The storage structure is opened inside the supporting column and communicates with the river upstream of the baffle. This patent uses a brush to clean the baffle, which ensures the smoothness of the through hole, increases the water flow rate, and improves the filtration efficiency. The pollutants are concentrated in the sewage chamber, which is convenient for the staff to salvage the pollutants and improves work efficiency. However, the amount of water passing through the river is different in different seasons. The amount of water passing through the river will increase significantly in the rainy season. The use of a fixed sewage interception mechanism cannot control the speed of water flow according to the water volume. The sewage interception mechanism may be damaged when a large water flow impacts the sewage interception mechanism, which also reduces the interception and filtration effect.

Since the sewage contains a large amount of water and occupies a large volume, the space utilization rate is low, resulting in the need for staff to frequently clean the sewage chamber, reducing work efficiency. Therefore, a river sewage interception device is proposed to solve the above problems. Utility Model Content
