Shaft type water inlet/outlet structure for pumped-storage power station

The utility model discloses a shaft type water inlet/outlet structure for a pumped-storage power station. The water inlet/outlet structure comprises a cover plate, a shunt pier and a vertical shaft, wherein the vertical shaft is composed of a vertical diffusion section, a vertical section, a turning section and a transition section sequentially, and the diameter of the cover plate is 1.1-1.5 times of that of an diffusion end of the vertical diffusion section; the length of the vertical section is larger than a vertical section hole diameter, the turning section is in a spindle shape which is expanded firstly and then contacted, the largest cross section diameter of the spindle is 1.3-1.4 times of the vertical section hole diameter, the radius of the turning section is more than 2 times of the vertical section hole diameter, and the diffusion ratio of the transition section is 1: 11-1: 13. According to the shaft type water inlet/outlet structure, through contrast of hydraulic model tests with numerical simulat
