Description

Technical Field

[0001] The utility model relates to the technical field of maintenance of hydropower stations, in particular to a maintenance device for a surface orifice flow channel of a dam body for flood discharge. Background Art

[0002] Due to long-term operation, the walls of the dam body flood discharge channel will be eroded and worn to varying degrees, and regular maintenance is required.

In addition, the mobile vehicle is prone to unnecessary lateral movement, side deviation or even steering when moving along the surface hole flow channel, and the controllability and safety are not ideal.
