Description

Technical Field

[0001] The invention relates to the technical field of water conservancy engineering, and in particular to a visual control system for the opening of a pump station side-flipping hydraulic flap door. Background Art

[0002] Hydropower generation in water conservancy projects is a clean and renewable way of energy production. It uses the energy of water flow to drive the turbine to rotate, which in turn drives the generator to generate electricity. In water conservancy projects, water is impounded by building dams and other hydraulic structures to form a water level difference. When water flows from high to low, its huge potential energy is converted into kinetic energy, which impacts the turbine blades to make them rotate. The turbine is connected to the generator to convert mechanical energy into electrical energy. Hydropower generation has many advantages. It does not produce pollutants and is environmentally friendly. Once the water conservancy project is built, the operating cost is relatively low. In addition, the water resources are abundant and sustainable. At the same time, hydropower generation can also play a comprehensive role in flood control, irrigation, water supply, etc., providing stable and reliable power support for the economic development of the region and people's lives.

[0003] The flap gate is an important device in water conservancy projects. The flap gate is mainly installed at the outlet of the drainage pipe to prevent water from flowing back. It is usually composed of door panels, door seats, hinges and other components. When the water flows forward, the flap gate opens under the thrust of the water flow, allowing the water to flow out smoothly; when the water flow stops or reverse water flow occurs, the flap gate will quickly close under the action of gravity and water pressure, thereby effectively preventing external water from flowing back into the drainage pipe system; At present, the flap gates in water conservancy project pumping stations are opened and closed by travel switches. The opening angle of the hydraulic flap gate affects the amount of water flowing through. However, since the angle of the hydraulic flap gate is affected by many factors such as flow velocity and water pressure, the angle of the flap gate will still change slightly after the flap gate is opened by the travel switch. However, the opening and closing angle and current specific status of the flap gate cannot be directly fed back to the command center of the water conservancy project pumping station at a distance, thereby affecting the precise control of the water conservancy project pumping station over the discharge volume. For this reason, we propose a visual control system for the opening of the pumping station's side-flip hydraulic flap gate. Summary of the invention
