[0002] Water conservancy projects are projects built to eliminate water disasters and develop and utilize water resources. According to their service objects, they are divided into flood control projects, farmland water conservancy projects, hydropower projects, waterway and port projects, water supply and drainage projects, environmental water conservancy projects, and sea reclamation projects. Water conservancy projects that can serve multiple purposes such as flood control, water supply, irrigation, and power generation are called comprehensive water conservancy projects. Water conservancy projects often use pumps to extract water from rivers or canals.

[0003] During the pumping process of water conservancy projects, it is inevitable that silt will be pumped out. After a long time, the accumulated silt will block the pumping pipe at the input end of the water pump, especially some block silt, which is more likely to cause the pumping pipe at the input end of the water pump to be blocked, affecting the pumping speed. Therefore, the silt in the pumping pipe at the input end of the water pump needs to be cleaned.

[0004] Therefore, we make improvements to this and propose a dredging device for water conservancy projects. Utility Model Content
