Reservoir ecological flow discharge structure
The invention discloses a reservoir ecological flow discharge structure, and belongs to the field of water conservancy and hydropower. The structure comprises a diversion tunnel and a discharge pipe,wherein the diversion tunnel is arranged at the bottom of a reservoir; the discharge pipe is arranged in the reservoir and communicates with the output end of the diversion tunnel; a drainage pipe isarranged at the bottom of the reservoir and is located at the rear end of the discharge pipe; the drainage pipe is arranged along the bottom of the reservoir and communicates with the bottom end of the discharge pipe; the discharge pipe is perpendicular to the bottom of the reservoir; and the height of the input end of the discharge pipe is higher than a dead water level of the reservoir and is lower than a normal impounding level of the reservoir. The structure is economical in manufacturing cost and convenient to overhaul, can meet the water inlet requirement that the height difference between the silt height of the reservoir and the dead water level is small, and is suitable for reservoirs with higher silt height.
本发明公开了一种水库生态流量下泄结构，属于水利水电领域。包括设置在水库底的导流洞以及设置在水库内并与导流洞输出端连通的下泄管，所述水库底并位于下泄管后端设有引流管，所述引流管沿水库底设置并与下泄管底端连通，所述下泄管与水库底垂直设置，并且所述下泄管输入端的高度高于水库的死水位并低于水库的正常蓄水位，本发明造价经济且检修方便，可满足水库淤沙高度与死水位高差小的进水要求，适用于水库淤沙高度较高的水库。
