Arc-shaped lifting ecological gate

Abstract

The invention discloses an arc-shaped lifting ecological gate. A dam body is provided with a gate groove. An arc-shaped gate blade is arranged in the gate groove, and two support arm grooves are formed in the downstream face of the gate groove and communicate with the gate groove. Support arms are arranged in the support arm grooves. The support arms and the arc-shaped gate blade are fixedly connected into a whole. Each support groove is internally and fixedly provided with a buttress. Each buttress is movably connected with the corresponding support arm through a hydraulic oil cylinder. The upper portion of each buttress is fixedly provided with a gate blade support. Each gate blade support is movably connected with the corresponding support arm through a gate blade rotating shaft. The arc center of the arc-shaped gate blade is consistent with the center position of the gate blade rotating shaft. According to the arc-shaped lifting ecological gate, protruding buttresses on the outer surface of the dam body are completely removed, and therefore the problem that when the gate is in a completely open state, the gate blade and the buttresses resist water and rubbish is solved, the discharge capacity is greatly improved, and the natural ecological environment requirement of a river way is achieved.

Description

technical field [0001] The invention relates to the technical field of gates, in particular to an arc-shaped lifting ecological gate. Background technique [0002] It is known that a gate is a control facility for closing and opening a water channel, which is an important part of a hydraulic structure and can be used to intercept, control water flow, control water level, regulate flow, discharge sediment and floating objects, etc. [0003] The gate types of existing gates are as follows: steel dam gates, hydraulic flap gates, hydraulic lifting dams and pneumatic shield gates, and steel dam gates, hydraulic flap gates and hydraulic lifting dams are used more. [0004] Steel Dam Gate—Steel Dam Gate is a new type of adjustable overflow gate in China in recent years, which is suitable for long-span and low water head conditions. The steel dam gate is also called the bottom shaft driven flap gate. The gate is composed of door leaf, fixed bottom shaft, hinge seat, crank arm, wall...

AI Technical Summary

Problems solved by technology

The operation of the gate is to rotate around the hinge seat at the bottom. When it is fully opened, it can lie flat on the gate floor. Generally, the horizontal gate is operated by a hydraulic hoist or hoist hoist, which is difficult to meet the requirements for large-span water retention. Hydraulic lift dams The structure of the door body is thin, the inspection and maintenance conditions of the moving parts of the door body and the water seal are poor, and the hydraulic cylinder is in long-term work, and the capacity of the hydraulic hoist is large, and the synchronization of the hydraulic system is highly required, otherwise the gate will be seriously damaged
