Full-open type hydraulic control flap gate and using method thereof

Abstract

The invention discloses a full-open type hydraulic control flap gate and a using method thereof. The full-open type hydraulic control flap gate comprises a dam body, a bottom watertight rubber, a gate leaf support, a gate leaf shaft, a large support rod shaft, a large support rod, a piston rod shaft, a small support rod shaft, a small support rod, a gate leaf hinged support, a gate leaf hinged support shaft, a gate leaf, a hydraulic cylinder, a support seat, a buffer rubber gasket, a side watertight rubber, a cylinder shaft and a hydraulic system. The gate and the method thereof are suitable for storing and draining water of a dam. Water storage, opening and closing of the gate are completely controlled by the hydraulic system, the large support rod and the small support rod support the gate when the gate is closed, thus the hydraulic cylinder is avoided being stressed for a long time, the gate can be completely opened so that the water flow reaches the maximum value, various defects of the traditional flap gate are overcome, the opening and closing accuracy is remarkably improved, no shaking phenomenon exists, the gate can not generate beating and floating phenomena, and the hydraulic system can realize the remote real-time monitoring. One full-open type hydraulic control flap gate can be used and a plurality of full-open type hydraulic control flap gates can also be simultaneously used, and the full-open type hydraulic control flap gate has the advantages of simple structure, low cost and remarkable technical advantages.

Description

technical field [0001] The invention relates to a fully-opening hydraulically controlled flap gate and a method for using the flap gate, in particular to a structure using the flap gate for fields requiring high passability. Background technique [0002] The flap gate is a kind of water retaining structure, which is used for water storage and discharge of dams. The traditional flap gate is a hydraulic self-controlled flap gate, which is a gate designed according to the principle of leverage. When the upstream water level exceeds the normal water storage level, the flap gate will automatically open. The higher the water level, the greater the opening amount. When this type of flap gate is fully opened, the upper and lower sides of the water-retaining part pass through the water, which makes it difficult for moving objects to pass through, and even directly hits the water-retaining part to damage the flap gate. After this type of flap gate is opened to a certain extent, when ...

Problems solved by technology

When this type of flap gate is fully opened, the upper and lower parts of the water-retaining part pass through the water, which makes it difficult for moving objects to pass through, and even directly hits the water-retaining part to damage the flap gate.

After this type of flap gate is opened to a certain extent, when the water retaining part of the flap gate has water passing through both the upper and lower parts, the water retaining part of the flap gate forms an angle with the water flow under the water, which is likely to cause "slapping", floating away, etc.

[0003] The structure of the traditional flap gate is complicated, and there are many redundant constraints. Among them, the commonly used slide rail and roller structure are easy to rust and be blocked by debris, especially the slide rail, which has low reliability and increases the turning resistance of the flap gate. When there are sundries, the slide rail is easy to get stuck, and after the gate is built, the start-up water level is unstable, the actual error is large, and it cannot be adjusted.

Moreover, the slide rail is easy to fall off, and the weight distribution of the flap gate is unreasonable, which makes the flap gate easy to be washed away

The opening and closing of the traditional hydraulic self-controlled flap gate is completely dependent on the level of the water storage level. The opening mode of the flap gate is passive, which cannot realize the timely opening of the flap gate. Moreover, the traditional flap gate mainly relies on the flap during the non-flood discharge period. The bottom of the gate is open for drainage, and the suspended garbage on the water surface cannot be removed. The suspended garbage is easy to get stuck in the lower part of the flap gate, so that the flap gate cannot be closed tightly.

The high dependence of the opening and closing of the flap gate on the water level leads to insufficient flood discharge capacity of the flap gate

[0004] The traditional flap gate is sealed with rubber and wood sandwiched in the rubber, which will be worn during the opening and closing process of the flap gate, and the wood is easily eroded by running water, resulting in a decrease in sealing ability and water leakage, requiring frequent replacement
