Water gate applied to Yellow River hydropower station

Abstract

The invention discloses a water gate applied to a Yellow River hydropower station. The structure of the water gate comprises a rotary table, a gate frame, a screw rod, a door sheet, a nut, a bottom groove and a shaking device, wherein the bottom of the gate frame is connected with the bottom groove; guide rails are arranged on the two sides of the gate frame; the door sheet is arranged in the guide rails on the two sides of the gate frame; the nut is welded with the top of the door sheet; the screw rod is mounted in the middle of the gate frame; the screw rod is connected with the nut throughthreads; the top of the screw rod penetrates through the top of the gate frame and is connected with the rotary table; a cavity is formed in the interior of the door sheet; the bottom of the door sheet is not sealed; the shaking device is mounted inside the door sheet; the shaking device comprises a wire wheel, pulleys, a stay cord and swinging mechanisms; the wire wheel is connected with the topof the screw rod; the pulleys are arranged on the two sides of the wire wheel; the pulleys are connected with the top of the gate frame; the swinging mechanisms are arranged on the two sides of the interior of the door sheet. The water gate has the beneficial effects that the shaking device is driven through the move-down power of a gate to shake water, sands fly upward, accumulation of sands is avoided, abrasion to the gate by sands is reduced when the gate is closed, and the gate is more tightly closed.

Description

technical field [0001] The invention relates to the field of hydropower station equipment, in particular to a sluice for the Yellow River hydropower station. Background technique [0002] The hydropower station controls the closing and opening of the discharge channel through the gate, which is an essential device for the hydropower station. [0003] Hydropower stations are also built on the Yellow River water system. The water quality of the Yellow River is more sandy than water. When the gate is closed, sand and soil are often accumulated at the bottom, which causes the gate to be worn by sand and soil when it is closed, causing damage to the gate. Strict, can not guarantee cut-off. Contents of the invention [0004] The main purpose of the present invention is to overcome the deficiencies of the prior art and provide a sluice for the Yellow River Hydropower Station. [0005] The present invention adopts the following technical solutions to achieve: a sluice for the Ye...
