High water head plane gate structure and gate hinge

Abstract

The invention discloses a high water head plane gate structure and a gate hinge, belongs to the field of the hydraulic and hydropower engineering, and provides a plane gate structure for reducing thephenomenon of gate groove cavitation erosion and cavitation. The gate hinge and gate grooves which are in guiding fit with the two sides of the gate hinge are included. A bottom sill is arranged at the bottom between the gate grooves in the two sides. The gate hinge comprises a gate hinge body and filling frames. The lower end of each of the two sides of the gate hinge body downwards extends to beprovided with a filing frame, an overflowing port is formed between the two filling frames, the bottoms of the gate grooves in the two sides downwards extend to be provided with sinking holes, and the filling frames can stretch into the sinking holes in the corresponding sides. Through the arrangement of the corresponding filling frames, the gate hinge can be constantly matched with the gate grooves through the filling frames in the gate hinge elevating process, accordingly it is ensured that the gate grooves are constantly in a filling state, the flatness of the inner side wall face of a runner is kept, water flow disturbance caused by the gate grooves is reduced, accordingly the phenomenon of cavitation erosion and cavitation at the positions of the gate grooves is avoided, the scouringaction on the gate grooves is reduced, and the service life of the gate grooves is prolonged.

Description

technical field [0001] The invention relates to the field of water conservancy and hydropower engineering, in particular to a high water head plane gate structure and gate leaves. Background technique [0002] High-head planar gates are commonly known as high-pressure sliding gates, which generally realize the opening and closing of the gate through the sliding fit of the door leaf and the door grooves arranged on both sides of the door leaf. Due to the existence of the door slot, when the door leaf is lifted, the door slot will form a sudden groove structure on the inner wall of the flow channel. Under the condition of water erosion, especially under the action of high-speed water flow, the erosion phenomenon of the door slot is serious. , and will produce cavitation cavitation, which will cause serious damage to the door slot and reduce the service life of the door slot. Contents of the invention [0003] The technical problem to be solved by the invention is to provide...
