Double-acting steel flap gate

Abstract

The invention discloses a double-acting steel flap gate. The double-acting steel flap gate is characterized in that the double-acting steel flap gate comprises a dam foundation with a bottom water stopping interface and a side wall body with a side water stopping interface and further comprises a steel gate leaf, supporting piers are embedded into the dam foundation, the steel gate leaf is fixed to a support on the back of the steel gate leaf, a linkage device is connected with the lower portion of the support, an oil cylinder is connected with the upper portion of the support, the oil cylinder is controlled by a hydraulic power pump station and an electric control system, and side water stopping rubber and bottom water stopping rubber are arranged on the steel gate leaf. The double-acting steel flap gate has the advantages that strength is high, and running is stable and reliable; opening and closing are controlled hydraulically, the drainage capacity can be freely adjusted, and remote real-time monitoring can be achieved; the flap gates can be used independently, and the multiple flap gates can also be used simultaneously side by side; each flap gate is completely independent, the corresponding hydraulic control system can be started according to the user requirements, and therefore the storage level can be adjusted by opening a certain number of flap gates, and the upstream submerged area can be effectively reduced by accurately starting the low water level during the flood.

Description

technical field [0001] The invention relates to a gate, in particular to a steel double-action flap gate, which is suitable for water storage and discharge of dams. 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. The traditional application material of this type of flap gate is reinforced concrete prefabrication. Because the material strength is average, the door panel and legs are high-frequency movable components, which may easily cause component damage or local damage, and objects moving in the water may even directly hit the water barrier. Partial damage to the flap gate and so on. T...

Problems solved by technology

The traditional application material of this type of flap gate is reinforced concrete prefabrication. Because the material strength is average, the door panel and legs are high-frequency movable components, which may easily cause component damage or local damage, and objects moving in the water may even directly hit the water barrier. Phenomena such as partial damage to the flap gate

The components of this type of flap gate are self-heavy, difficult to construct, and the cycle is long, which affects the benefit, especially the difficulty in later maintenance

[0003] The structural strength of the traditional flap gate is average, and there are many redundant constraints. Its span and height are limited to a certain extent. As the gate height and span increase, the requirements for materials will become higher and higher, and material replacement will become inevitable.

After the gate is built, there are disadvantages such as small starting water level, large actual error, and inability to adjust, 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 gated flap gate is completely dependent on the level of the water storage level. The flap gate is opened passively, and it is impossible to observe the timely opening of the flap gate. Moreover, the traditional flap gate mainly relies on The bottom of the flap 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] In addition, the traditional flap gate is sealed with rubber and wood sandwiched in the rubber. The rubber will be worn during the opening and closing process of the flap gate, and the wood is easily eroded by flowing water, which will reduce the sealing ability of the flap gate and cause Water leaks and therefore requires frequent replacement
