Underwater manned testing door special for cleaning slot of steel gate of hydropower station

Abstract

The invention discloses an underwater manned testing door special for cleaning a slot of a steel gate of a hydropower station. The underwater manned testing door special for cleaning the door slot of the steel gate of the hydropower station comprises a box-type main body, an upstream panel and a downstream panel, wherein the rear side surface in the length direction is the upstream panel, and the front side surface in the length direction is the downstream panel; the downstream panel is provided with a mandoor, a side support, a main support as well as a plurality of flat pressing water inlets; the top of the box-type main body is provided with a lifting lug and a wire communicating pipe communicated with the inside; side column flat pressing water inlets are formed in side columns at two ends of the box-type main body; the inner wall of the upstream panel is provided with a plurality of longitudinal beams in the vertical direction; a U-shaped main beam is horizontally arranged between the two adjacent longitudinal beams; a base plate of each U-shaped main beam is fixedly connected to the inner wall of the upstream panel; the half side, close to the downstream, in the box-type main body is provided with a working channel communicating left and right; the bottom of the working channel is provided with holes facilitating underwater cleaning, and safety guardrails are arranged close to the holes. The underwater manned testing door special for cleaning the slot of the steel gate of the hydropower station, which is provided by the invention, can be used for solving the key technical problems of underwater photographing inspection and cleaning of the slot of the steel gate and total-travel passing inspection of a gate running orbit.

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...
