Double-layer arc gate automatic switch

Abstract

The invention discloses an automatic switch of a double-layer arc gate, which comprises a control mechanism on a dam, and is characterized by further comprising an open arc gate arranged on an upper layer and a culvert arc gate arranged on a lower layer, wherein concrete interlayers at intervals are arranged in the middle; a culvert arc main gate which is close to a high-flow and high-water head and at the front of the dam is divided into an arc main gate and an arc maintenance gate which are on upper and lower layers; the control mechanism comprises a contraction steel rope, a gear, a rack, a linkage wheel, a steel rail and a non-return device; and a driving wheel, a cooperating gate bracket and a cooperating gate are arranged on the opposite side of the open arc gate. The automatic switch has the advantages of simple structure, low construction cost, safety, firmness and the like.

Description

technical field [0001] The invention relates to the technical field of water conservancy equipment, and more specifically relates to an automatic switch of a double-layer arc gate. Background technique [0002] At present, the gates of hydropower stations, such as the Gezhouba double-layer gate with large flow and large opening; the gate chamber is an open flat bottom gate, the gate floor elevation is 43 meters, the gate opening is 12 meters wide and 24 meters high, and the upper layer is a plane gate. There is an arc gate on the lower floor. There is a horizontal plane compartment in the middle, with a maximum flow rate of 83900m3, a total of 27 orifices, three holes connected to each other, and the overall structure is divided into 9 gate sections. The purpose is to facilitate flood discharge and adjust river regime for power generation and navigation. The traditionally designed gate technology and the similar double-layer gates of Gezhouba have the following defects; ...

AI Technical Summary

Problems solved by technology

[0003] 1. The traditional opening and closing pavilions are higher than the dam surface, and professionals need to use power to operate at high altitudes and long distances to open and close the switches;

[0004] 2. Due to the traditional double-layer doors with super-high obstacles on the hoist platform, the gate floor cannot reduce the water level difference to wash sand;

[0005] 3. The traditional pair of double-layer arc gates cannot share a control automatic switch under the upper dam surface;

[0006] Fourth, the traditional can not realize that both double-layer arc gates are automatic switches;

[0007] 5. The traditional breakthrough improvement needs to increase the high head of the double-layer arc gate, so that the convenience of energy storage is not enough
