Multifunctional gate and operation method thereof

Abstract

The invention discloses a multifunctional gate and an operation method thereof, and belongs to the technical field of hydraulic engineering equipment and machinery. The multifunctional gate is formedby combining two same fan-shaped gate structures, and the radial gates are formed by combining a plurality of hanging pieces, so that water blocking at the upstream side and water passing at the downstream side are realized; a main shaft capable of lifting up and down is provided with a jacking, and the jacking can be clamped in a concave structure of the fan-shaped gates to fix the fan-shaped gates when the two fan-shaped gates are in butt joint; a base consists of an upper turntable and a lower chassis, and the upper turntable can be driven to rotate by driving a gear in the base so as to drive the fan-shaped gates to rotate; telescopic grab handles are arranged on the two sides of a gate chamber, and the two fan-shaped gates are pulled to the two sides of the gate chamber when flood driving requirements exist; and a water spraying device is also arranged to achieve a landscape water spraying effect. According to the multifunctional gate and the operation method thereof, a fishway and the gate are combined into one, so that the cost is saved; and multiple functions of fish luring, rotary fish driving, landscape water spraying, water blocking, flood driving and drainage and the like can be realized.

Description

technical field [0001] The invention belongs to the technical field of hydraulic engineering equipment and machinery, and in particular relates to a multifunctional gate and an operating method thereof. Background technique [0002] The fishway is a kind of fish passage structure, which is an artificial tank for fish to migrate through the barrage structure. The design of the fishway mainly considers the upward habit of fish. In the downstream of the barrage structure, fish often rely on the attraction of the water flow to enter the fishway, and the fish rely on their own strength to overcome the flow velocity and swim upstream in the fishway. With the continuous construction of a large number of water conservancy facilities, the living environment of fish has been seriously threatened. The barrage structures cut off the upstream and downstream water flow, making it impossible for fish in the original river to migrate, resulting in the reduction or even extinction of a large...

AI Technical Summary

Problems solved by technology

Existing fishways have shortcomings such as inability to meet the needs of different fish migrations, low fish passing efficiency, unsuitable demands, and high water head difference blocking structures.
