Upper reservoir water inlet and outlet structure of hybrid pumped storage power station
The invention discloses an upper reservoir water inlet and outlet structure of a mixed pumped storage power station, which comprises a water inlet and outlet main body arranged on an upper reservoir of the mixed pumped storage power station, a water blocking ridge is arranged in the upstream direction of the water inlet and outlet main body, and a gate assembly is arranged on the water blocking ridge and comprises a liftable door plate; the door plate is connected with a buoyancy box assembly capable of driving the door plate to ascend and descend through buoyancy of the buoyancy box assembly. The highest rising elevation of the door plate is equal to the power generation ecological water temperature water taking level, the top elevation of the water blocking bank is lower than the lowest power generation water level of the mixed pumped storage power station, and the bottom elevation of the water blocking bank is equal to the dead water level of a conventional power station. The arrangement elevation of the water inlet main body can be increased, the work amount of excavation of the bottom and the slope of the water inlet main body can be reduced, it is guaranteed that when an upper reservoir stores water at a high water level, a pumping and storage unit generates power and can take surface water, and it can be guaranteed that the water inlet and the water outlet have enough submerging water depth when the reservoir operates at a low water level, so that water outflow is smoother; the power generation efficiency of the power station is effectively improved.
本发明公开了混合式抽水蓄能电站的上水库进出水口结构，包括设置在混合式抽水蓄能电站上水库的进出水口主体，进出水口主体的上游方向设有拦水坎，拦水坎上设闸门组件，闸门组件包括可升降的门板，门板上连接有可通过自身浮力带动门板升降的浮箱组件；门板的最高上升高程等于发电生态水温取水位，拦水坎的顶部高程低于混合式抽水蓄能电站的最低发电水位，拦水坎的底部高程等于常规电站的死水位。本发明能够提高进水口主体的布置高程，能够减少进水口主体处底部及边坡开挖的工程量，保证上水库在高水位蓄水时抽蓄机组发电能够取表层水，能够保证在水库在低水位运行时进出水口具有足够的淹没水深，使得水体出流更加平顺，有效提高电站的发电效率。
