Vertical shaft type water inlet and outlet structure adopting equal-width gradual change pipe
The invention discloses a vertical shaft type water inlet and outlet structure adopting equal-width gradual change pipes, and belongs to the technical field of pumped storage power station engineering. Comprising a tunnel body section, a bend section, a vertical section and a diffusion section which are sequentially connected from bottom to top, the bend section comprises an upper arc bend pipe, a middle transition bend pipe and a lower arc bend pipe, the axis of the bend section is a non-concentric arc, and the cross section of the bend section is an equal-width long circle; and the axes of the cover plate, the shunting pier, the diffusion section, the vertical section and the curve section are positioned on the same vertical plane. The equal-width gradually-changing pipe structure is applied, hydraulic indexes such as water inlet and outlet head loss, flow velocity distribution and flow distribution of all orifices under the combined working condition and various hydraulic indexes of a traditional elbow type are located on the same level, and the construction technology is simplified. The device breaks through the existing engineering experience, is simple in structural design and obvious in effect, and can be widely popularized and applied in pumped storage power station engineering.
本发明公开了一种采用等宽渐变管的竖井式进出水口结构，属于抽水蓄能电站工程技术领域。包括从下到上依次连接的洞身段、弯道段、竖直段和扩散段，弯道段包括上圆弧弯管、中间过渡弯管和下圆弧弯管，其轴线为不同心圆弧，其横截面为等宽长圆形，扩散段顶部设置有分流墩和盖板，盖板、分流墩、扩散段、竖直段和弯道段的轴线均位于同一铅直面。本发明应用了等宽渐变管结构，组合工况下进出水口水头损失、各孔口流速分布和流量分配等水力学指标与传统肘型各项水力学指标处于同一水平，简化了施工工艺。本发明突破了已有工程经验，其结构设计简单，效果明显，可在抽水蓄能电站工程中广泛推广及应用。
