Description

Technical Field

[0001] The utility model relates to the technical field of pipeline anti-blocking devices, in particular to a water conservancy pipeline anti-blocking device. Background Art

[0002] As we all know, in water conservancy projects, it is often necessary to draw water from rivers. The water pipes for drawing water from rivers are usually equipped with filters with smaller mesh sizes to prevent larger foreign objects from entering the water pipes. Subsequently, filters with larger mesh sizes are set in subsequent branch pipes to filter out small debris. After two layers of filtration, debris can be prevented from entering the pipes to a great extent.

[0003] Regarding the above-mentioned related technologies, since water is taken from the river, the river water contains a lot of silt, which cannot be filtered by large-mesh filters or small-mesh filters. The filter is very likely to be blocked over a long period of time. Utility Model Content
