Outlet design method for improving vertical shaft outflow and water inlet and outlet structure based on outlet design method
The invention discloses an outlet design method for improving vertical shaft outflow and a water inlet and outlet structure based on the outlet design method, and belongs to the technical field of hydraulic engineering. The water inlet and outlet structure comprises a water flow channel, the water flow channel is provided with a vertical section, a water inlet and outlet is formed in the upper end of the vertical section, and flow dividing components are evenly distributed around the water inlet and outlet; the device is characterized in that the upper portion of the flow dividing component is arranged on the periphery above the water inlet and outlet to form a cylindrical retaining wall of a stopping structure, and the upper edge of the cylindrical retaining wall is higher than the dead water level of a reservoir area of the pumped storage power station. According to the vertical shaft type water inlet and outlet structure, the water flow uniformity, flow distribution and trash rack flow velocity distribution are remarkably improved by introducing the buffer water body and optimizing the design, the reverse flow velocity problem is thoroughly eliminated, the operation safety of a power station is improved, the service life of equipment is prolonged, and economic benefits are increased.
本发明公开了一种改善竖井出流的出口设计方法及基于其的进出水口结构，属于水利工程技术领域，进出水口结构包括水流通道，所述水流通道具有竖直段，所述竖直段的上端为进出水口，所述进出水口周围均布分流构件，其特征在于：所述分流构件的上部设置在所述进出水口上方周围形成止挡构造的筒形挡墙，所述筒形挡墙的上边缘高度高于抽水蓄能电站的库区死水位。本竖井式进出水口结构通过引入缓冲水体和优化设计，显著改善了水流均匀性、流量分配和拦污栅流速分布，彻底消除了反向流速问题，提升了电站运行安全性、设备寿命和经济效益。
