Description

Technical Field

[0001] This utility model relates to the technical field of river pollution prevention equipment, specifically a detachable river pollution prevention device that enhances pollution prevention and erosion protection. Background Technology

[0002] River pollution curtains are pollution prevention devices used in rivers. They are usually installed around river construction equipment or perpendicular to the river to intercept water flow. Their main function is to prevent the spread of pollutants, thereby keeping the river water clean. They can effectively reduce pollutants in the water and reduce the impact of suspended solids from water-related construction on inland rivers and aquatic ecosystems.

[0003] In existing technologies, river channels typically employ fully enclosed pollution curtains fixed to both sides with steel pipe piles. This method is widely used in inland waterways. However, this type of pollution barrier is only suitable for small rivers, lakes, and other areas with relatively calm water flow. In swift-flowing rivers, the underwater portion of the pollution curtain is washed away and floats, thus losing its effectiveness in blocking pollution. Furthermore, sand, gravel, and tree branches can become destructive in swift-flowing rivers. Once a part of the pollution curtain is damaged, the entire curtain needs to be replaced, significantly reducing its lifespan. This method is not only environmentally unfriendly but also difficult, time-consuming, and labor-intensive to replace. Utility Model Content
