Large-span tide-blocking service gate

Abstract

The invention relates to a large-span tide-blocking service gate, and belongs to the technical field of gates. The large-span tide-blocking service gate comprises a gate body, a rotation driving device, a sediment pressure sensing device, a first deposited sediment cleaning device, a second deposited sediment cleaning device and a controller, wherein the gate body comprises a lower gate body and an upper gate body which are arranged in a split mode, the lower gate body is used for being arranged at the river bottom, the two ends of the lower gate body in the length direction are used for being rotationally matched with gate piers on the two sides of a river mouth, the lower gate body is rotationally matched with the river bottom, the upper gate body is arranged above the lower gate body, the upper door body and the lower door body are in sliding and sealing fit, and the upper door body can move in the width direction of the river mouth relative to the lower door body. The large-span tide-blocking service gate is used for a strong tidal bore river mouth ship lock, and is safe, stable and low in maintenance cost.

Description

technical field [0001] The application relates to the technical field of gates, in particular to a large-span tide-blocking working gate. Background technique [0002] Compared with the traditional gate, the tide-blocking gate can take into account the functions of tide-blocking and navigation, and its importance is higher. Small-span tidal gates can be considered to use plane lifting gates or horizontal sliding doors, but for large-span (usually defined as more than 26 meters in length) tidal gates, in order to meet the requirements of strength, stiffness and stability, lifting gates The overall structure of the structural gate will be very heavy, and the requirements for the gate opening and closing equipment and hydraulic structures are higher, which is not conducive to the safe operation of the gate; when the horizontal sliding gate is used in a strong tidal estuary, the river sediment content is high. The lower part of the trolley is prone to silt and sand, and often n...

Small-span tidal gates can be considered to use plane lifting gates or horizontal sliding doors, but for large-span (usually defined as more than 26 meters in length) tidal gates, in order to meet the requirements of strength, stiffness and stability, lifting gates The overall structure of the structural gate will be very heavy, and the requirements for the gate opening and closing equipment and hydraulic structures are higher, which is not conducive to the safe operation of the gate; when the horizontal sliding gate is used in a strong tidal estuary, the river sediment content is high. The lower part of the trolley is prone to silt and sand, often needs to be dredged, and the maintenance cost is high
