Ecological water drainage pipe for centralized development of hydropower station

Abstract

The invention discloses an ecological water drainage pipe for centralized development of a hydropower station in the field of hydraulic and hydroelectric engineering. The ecological water drainage pipe is positioned in a power station plant, the upstream end of the ecological water drainage pipe communicates with a power generation steel pipe, and the downstream end of the ecological water drainage pipe leads to the downstream side of the plant; and a control valve is arranged on a pipeline of the ecological water drainage pipe, and an energy dissipation structure is further arranged at the downstream end of the pipeline. The ecological water drainage pipe has the beneficial effects that the ecological water drainage pipe is arranged in the power station plant, inflow water of the power generation steel pipe is introduced to serve as ecological water supply, then after water head energy is dissipated through the energy dissipation structure, the water head energy is drained to the downstream, a downstream riverway is protected, and the water pipe can be controlled to be opened and closed through the valve; and in addition, the ecological water drainage pipe is arranged in the powerstation plant, design and installation are convenient, and later overhauling and maintenance are also convenient.

Description

technical field [0001] The invention relates to the field of water conservancy and hydropower engineering, in particular to an ecological water discharge pipe used for centralized development of hydropower stations. Background technique [0002] After the dam cuts off the river, all the water flow is vented from other channels or powerhouse passages. When encountering dry season, the original river channel downstream of the dam is basically in a dry state. Therefore, it is necessary to set up a water release structure to meet the demand for ecological water supply and protect the ecological environment downstream of the dam. The general ecological water discharge pipe structure is arranged in the dam body, and is lower than the lowest water level, and is used to supplement the incoming water of the downstream channel. This type of ecological water discharge pipe is an independent structure that requires separate design, construction and management, which is inconvenient for...

AI Technical Summary

Problems solved by technology

This type of ecological water discharge pipe is an independent structure, which requires separate design, construction and management, which is not convenient for later maintenance, and the opening and closing of the water discharge pipe and the energy of the water head are not easy to control, causing erosion to the downstream river.
