Broken line type isolation pier structure for bidirectional uniform diversion of water inlet and water outlet of pumped storage power station
The invention relates to a broken line type isolation pier structure for bidirectional uniform diversion of a water inlet and a water outlet of a pumped storage power station. A pumped storage water inlet and outlet flow channel is divided into four sections including a tunnel section, a diffusion section, an adjusting section and an anti-vortex beam section in the whole process. The axis of a diversion isolation pier commonly adopted by an existing diffusion section is linear. The diversion isolation pier is divided into two sections to form a broken line type structure. The axis of the head section of the broken-line-type diversion isolation pier is parallel to the axis of the tunnel, and the tail section of the diversion isolation pier is obliquely connected with the adjusting section. The distance between the diversion isolation piers and the starting position of the broken line can be specifically adjusted according to actual engineering. According to the broken line type diversion isolation pier structure, the flow of a water inlet and a water outlet can be effectively and uniformly distributed to each flow channel, and the diversion nonuniformity can be reduced to be less than 5%.
本发明涉及抽水蓄能电站进出水口双向均匀分流的折线型隔墩结构，抽水蓄能进出水口流道全程分为四段：隧洞段、扩散段、调整段、防涡梁段。目前扩散段普遍采用的分流隔墩轴线是直线型。本发明将分流隔墩分成两段，形成折线型结构。折线型分流隔墩首部段的轴线与隧洞轴线平行，分流隔墩尾部段则斜向与调整段相连。分流隔墩的间距，折线起始的位置，均可以根据实际工程做具体调整。本发明的折线型分流隔墩结构，可有效将进出水口流量均匀地分配至各流道，可将分流不均匀性降低到了5％以内。
