Egg weir structure for protecting fish eggs in lower reservoir lake area of pumped storage power station
The invention discloses an egg weir structure, particularly discloses an egg weir structure for protecting fish eggs in a lower reservoir lake area of a pumped storage power station, and belongs to the technical field of design and manufacturing of ecological protection structures of water conservancy and hydropower engineering. According to the egg weir structure for protecting the fish eggs in the lower reservoir lake area of the pumped storage power station, the influence of periodic decline of the water level of the lower reservoir on the viscous fish eggs can be eliminated under the working condition of pumped storage of the pumped storage power station. The egg weir structure comprises an artificial egg laying area, a base weir and a movable adjusting weir, the artificial egg laying area arranged in a lower reservoir lake of the pumped storage power station and close to a shallow water area of a bank slope is defined by the corresponding bank slope, the base weir and the movable adjusting weir, and the movable adjusting weir is movably arranged on the base weir. The water level of the artificial spawning area is determined through the cooperation of the movable adjusting weir and the base weir.
本发明公开了一种卵堰结构，尤其是公开了一种用于抽水蓄能电站下库湖区鱼卵保护的卵堰结构，属于水利水电工程生态保护结构物设计制造技术领域。提供一种抽水蓄能电站在抽水储能工况下能消除下库水位周期性下降对粘沉性鱼卵产生影响的用于抽水蓄能电站下库湖区鱼卵保护的卵堰结构。所述的卵堰结构包括人造产卵区、基堰和活动调节堰，设置在抽水蓄能电站下库湖泊靠近岸坡浅水区的人造产卵区通过相应的岸坡、基堰和活动调节堰围建而成，所述的活动调节堰活动的布置在所述的基堰上，人造产卵区的水位通过活动调节堰在基堰的配合调节确定。
