Description

Technical Field

[0001] The utility model belongs to the technical field of pollution cleaning devices, and in particular relates to a river pollution cleaning device. Background Art

[0002] The trash rack is a mechanical device that removes debris attached to the trash rack. The grille cleaner in the trash rack uses a motor to drive the chain to rotate in the opposite direction of the water flow, thereby driving the trash discharge plate to move in the opposite direction of the water flow, so that the trash discharge plate intercepts floating objects in the water and scrapes floating objects on the trash rack. As the chain continues to rotate, it drives the trash discharge plate to carry the floating objects to the bank of the river, where they fall to the ground due to their own gravity.

[0003] A large amount of floating debris is most likely to accumulate and float near the dam as the river flows. Many cities currently use pollution-clearing ships combined with manual salvage to remove floating debris. This cleaning work is limited by manual labor and high temperatures in summer, resulting in low cleaning efficiency and consuming a lot of manpower. Utility Model Content
