Improving method and structure of water release gate submerged orifice plane emergency gate

Abstract

The invention discloses an improving method and structure of a water release gate submerged orifice plane emergency gate. The water release gate submerged orifice plane emergency gate is moved to theupstream side of the outside of a water release gate breast wall from the inside of the water release gate breast wall, and therefore the water release gate breast wall does not need to be built to bethick, and investment cost of a water release gate is reduced; meanwhile, a panel on the upstream side of the plane emergency gate, a top beam and side columns are welded into a closed body, a top water seal and a side water seal of the plane emergency gate are arranged on the downstream side of the plane emergency gate and are connected with the bottom water seal to form a water seal device withthe closed periphery, water on the upper portion of the plane emergency gate forms downward water column pressure on the plane emergency gate, and therefore when the plane emergency gate is closed, abalance weight does not need to be additionally arranged, and the mounting program of the plane emergency gate is simplified. The defects that in the prior art, a breast wall and the gate are large in thickness, during door closing, the balance weight needs to be arranged, during water filing for flat pressing, the water flow range is far, an arc work gate panel is easily impacted, and vibrationof an arc work gate is induced.

Description

technical field [0001] The invention relates to an improvement method and structure of a submerged hole plane accident gate of a sluice gate, which belongs to the technical field of metal structures of water conservancy and hydropower projects. Background technique [0002] In water conservancy and hydropower projects, the submerged hole plane accident gate of the sluice generally adopts the upstream water stop fixed wheel support type or the downstream water stop slide block support type. The gate adopts the upstream water-stop fixed wheel support type. Since the gate slot is arranged in the breast wall of the sluice, the thickness of the breast wall is relatively large; this type of gate usually cannot overcome the closing resistance by relying on its own weight, and requires additional counterweight, civil engineering and metal structure investment. Larger; if the gate adopts the downstream water-stop slider support type, due to the large friction coefficient of the slide...

Problems solved by technology

[0003] The purpose of the present invention is to provide an improved method and structure of a submerged hole plane accident gate of a sluice sluice to overcome the large thickness of the breast wall and the gate in the prior art, the need to add a counterweight when the accident gate is closed, the large door groove, and the water The mechanical conditions are not good, cavitation, cavitation and other phenomena are prone to occur, and when the hydraulic pressure is filled, the water flow has a long range, and it is easy to impact the arc-shaped working gate panel, which induces the lack of vibration of the arc-shaped working gate.
