A double-leaf hydraulic gate with gravity opening and closing

Abstract

The invention discloses a double-leaf hydraulic gate capable of being opened and closed under the effect of gravity. The gate is characterized in that a double-leaf gate comprising an upper gate and a lower gate is arranged in a gate hole; a bent for supporting the gates comprises a top beam and stand columns on two sides; fixed pulleys are mounted on the top beam; the upper gate and the lower gate are suspended on the fixed pulleys by the aid of fixed-length steel cables and can be in up-and-down translation linkage; the upper gate comprises a water storage cavity, water is injected into the water storage cavity, the weight of the upper gate can be increased, and the upper gate descends and the lower gate ascends until the gate is closed; or the water in the water storage cavity is discharged, the weight of the upper gate is reduced, and the upper gate ascends and the lower gate descends until the gate is opened; and a U-shaped diving gate groove is formed below a gate bottom plate, and the lower gate sinks into the groove during opening of the gate. The hydraulic gate is opened and closed under the effect of gravity, the manufacturing cost and the operation and management cost can be greatly saved, and the operation reliability of the gate can be improved.

Description

technical field [0001] The invention relates to a hydraulic gate, more specifically a double-leaf hydraulic gate which divides the gate into two, realizes opening and closing by gravity, and lowers the gate to dive. Background technique [0002] At present, the commonly used hydraulic gates in my country mainly include vertical plane steel gates, arc gates and traditional double-leaf gates. The phenomenon of opening and closing failure or failure to open and close occurs from time to time due to overload or insufficient power. High-power hoists have certain requirements for power distribution infrastructure. This makes the traditional hydraulic gate technology not match the actual operating environment in the environment of deviation conditions, such as small and medium-sized reservoirs with small storage capacity and high water head in mountainous areas, which reduces the reliability of sluice operation. At the same time, the existing hydraulic gates are all opened upwards...

Problems solved by technology

This makes the traditional hydraulic gate technology not match the actual operating environment in the environment of deviation conditions, such as small and medium-sized reservoirs with small storage capacity and high water head in mountainous areas, which reduces the reliability of sluice operation.

At the same time, the existing hydraulic gates are all opened upwards, resulting in excessive structural height of the hoisting platform and poor seismic capacity of the structure
