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 technical solution of the present invention is achieved in the following way: a gate opening and closing device, including a dam body, a drain channel is provided at the lower end of the dam body; a gate for opening and closing the drain channel is longitudinally slid on the dam body, and installed There is an opening and closing device for controlling the longitudinal reciprocating movement of the gate, which is characterized in that an opening and closing beam is fixed above the gate, and the opening and closing equipment includes a winch and a traction mechanism for connecting the winch and the gate and respectively installed on both sides of the gate , the winch is installed above the dam body; the traction mechanism includes a first traction part for pulling up the gate and a second traction part for helping the gate to close; The problem of closure can be improved to improve the safety performance of the dam body.

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...
