Ecological protection channel of hydropower station basin and its automatic adjustment tank and floating constant current gate

Abstract

The invention discloses a hydropower station watershed ecological protection channel and an automatic adjustment water channel and a floating constant-current gate thereof. According to the hydropower station watershed ecological protection channel and the automatic adjustment water channel and the floating constant-current gate thereof, the structure is reasonable, and it is beneficial for aquatic creatures in the downstream watershed to swim to the upstream breeding place to lay eggs and breed, the requirements for normal power generation and operation of water-power engineering are met while the environment of the hydropower station watershed and reasonable drainage of water for ecological protection can also be effectively guaranteed, it is guaranteed that the economic benefits and the social benefits of ecological and environmental protection can be achieved at the same time, and the target of building a green and environmentally-friendly type hydropower station is achieved in a real sense.

Description

technical field [0001] The invention belongs to the technical field of water conservancy and hydropower engineering construction, and relates to environmental and ecological protection in water conservancy and hydropower projects, in particular to an ecological protection channel for a watershed in a hydropower station, an automatic adjustment water tank and a floating constant-current gate. Background technique [0002] Building dams on natural rivers to develop and utilize water resources will benefit the people, but it will also have some negative impacts on the ecological environment. The environmental and ecological protection issues of the upstream and downstream river sections of water conservancy and hydropower project dams are the key to their construction and operation. The most important problem is that there are various ecological flow discharge facilities for hydropower projects, and their structural types include discharge tunnels, sluice gates, discharge pipes,...

[0002] Building dams on natural rivers to develop and utilize water resources will benefit the people, but it will also have some negative impacts on the ecological environment. The environmental and ecological protection issues of the upstream and downstream river sections of water conservancy and hydropower project dams are the key to their construction and operation. The most important problem is that there are various ecological flow discharge facilities for hydropower projects, and their structural types include discharge tunnels, sluice gates, discharge pipes, discharge bottom holes, etc., all of which meet the environmental protection requirements of the downstream water reduction river section. The discharge of ecological flow is carried out, but this discharge method is greatly affected by human control, and due to the location of the discharge water outlet, it will cause excessive water pressure or excessive drop, which will affect the water flow in the downstream basin. Organisms swim to the upstream breeding grounds to reproduce, blocking the migration channels of aquatic organisms, destroying the spawning grounds and reducing the amount of fishery resources. It is often destructive. The construction of water conservancy dams will inevitably affect the connection between upstream and downstream organisms. Some organisms cannot visit the habitats they need. Over time, many precious species may disappear.
