Problems solved by technology

[0003] At present, the gate on the dam relies on its own gravity in the process of lowering the gate. However, due to the depth of the water, the water pressure on the gate is relatively high, resulting in a large friction force between the gate and the track, and the friction force when the gate is lowered If the direction is upward, it is difficult to control the amount of water in the river during the rainy season. When the amount of water is too much, the friction force will be greater than its own weight. The winch hoist without downforce cannot completely close the gate, and it is difficult to achieve the effect of cutting off the water flow. And the gate It is unstable and has great potential safety hazards. Therefore, it is necessary to improve the existing hoist-type gate opening and closing device

Abstract

The invention discloses a gate opening and closing device. According to the technical scheme, the gate opening and closing device comprises a dam body, a drainage channel is formed in the lower end ofthe dam body, and a gate for opening and closing the drainage channel is longitudinally arranged on the dam body in a sliding manner; and opening and closing equipment for controlling the gate to longitudinally reciprocate is mounted on the gate opening and closing device. The gate opening and closing device is characterized in that an opening and closing beam is fixed above the gate, and the opening and closing equipment comprises a winch and traction mechanisms which are used for connecting the winch and the gate and are correspondingly mounted on two sides of the gate, wherein the winch ismounted above the dam body; and each traction mechanism comprises a first traction part used for pulling the gate upwards and a second traction part used for helping the gate to be closed. Accordingto the gate opening and closing device, the problem that the gate cannot be completely closed by means of self weight is effectively solved, and the safety performance of the dam body is improved.

Description

technical field [0001] The invention relates to the technical field of gate control, in particular to a gate opening and closing device and a control method thereof. Background technique [0002] The gate is a control facility for closing and opening the discharge (discharging) channel; as an important part of a hydraulic structure, it can be used to intercept water flow, control water level, adjust flow, discharge sediment and floating objects, etc.; gate It is usually used in hydraulic structures such as overflow dams, bank spillways, scuppers and hydraulic tunnels. It has the functions of intercepting water flow, controlling water level, regulating flow, controlling shipping, and discharging sediment and floating objects. [0003] At present, the gate on the dam relies on its own gravity in the process of lowering the gate. However, due to the depth of the water, the water pressure on the gate is relatively high, resulting in a large friction force between the gate and th...
