Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, and particularly relates to a silt cleaning device for water conservancy projects. Background Technique

[0002] Silt cleaning in water conservancy projects generally refers to river silt cleaning, that is, treating the river silt deposited at the bottom of the river. As a carrier for transporting water resources, the river causes soil migration during the flowing process, and the deposition of soil is the main reason for river siltation. To restore the normal function of the river, it is necessary to clean the silt in the river.

[0003] Currently, most of the existing silt cleaning devices pump up the silt in the river. If the pumped-up silt is directly discharged, it will cause secondary pollution and the silt cleaning effect is not good. After years of deposition at the bottom of the river, when working, some silt in the river that has been accumulated for a long time may be difficult to directly pump up.

[0004] Based on this, the utility model designs a silt cleaning device for water conservancy projects to solve the above problems. Content of the Utility Model
