Description

technical field

[0001] The invention relates to an underwater manned test door specially used for cleaning the gate groove of a steel gate of a hydropower station, and belongs to the technical field of the hydropower station. Background technique

[0002] The installation of the steel gate slots of hydropower stations is carried out along with the construction progress of the dam, and the diversion bottom hole sluice chamber or the flood discharge bottom hole sluice chamber is often flooded in advance due to the need for cofferdam closure or flood season. Because the flowing water contains a lot of sediment and sundries, it is easy to form silt and jam in the installed gate groove, which will seriously affect the smooth closing of the steel gate in the subsequent dynamic or still water state, making the steel gate impossible. Closed in place, causing water leaks or steel gates to get stuck. Therefore, it is necessary to clean up the silt and sundries in the slag door groove...
