Technical Field

The utility model relates to the technical field of water conservancy projects, in particular to a water conservancy project silt removal device.

Background technique

In water conservancy projects, silt removal devices are needed to remove silt at the bottom of ditches. However, when existing devices suck in silt water during operation, the agglomerated silt therein will block the pipeline, causing damage to device components and resulting in cost losses. At the same time, the sludge water suction structure of the existing device cannot be adjusted, and operations cannot be carried out in a targeted manner, which affects the silt removal efficiency.

The existing Chinese patent with the announcement number CN217759027U discloses a water conservancy project silting device, which relates to the field of water conservancy project technology.
