Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy and hydropower engineering, in particular to a cleaning device for a dam. Background Art

[0002] Dam cleaning devices are equipment and systems specially designed for cleaning and maintaining water conservancy dams. The main purpose of these devices is to ensure the safety, stability and normal operation of the dam structure. Before cleaning, the high water level will be drained first, and then workers will use water guns to clean it.

However, the water flow pattern of traditional water guns is fixed, and the nozzle needs to be replaced when adjusted. Replacing the nozzle back and forth will waste a lot of time and reduce work efficiency. In addition, the stains generated during the flushing process will remain on the surface of the dam and need to be repeatedly cleaned later. Repeated cleaning takes a long time and has low work efficiency. Utility Model Content
