Well-type water inlet and outlet structure of pumped storage power station

The invention discloses a well-type water inlet and outlet structure of a pumped storage power station. The well-type water inlet and outlet structure comprises a cover plate, a dividing part and a vertical shaft. The vertical shaft includes a diffusion section, a vertical section, a turning section and a gradual change section; the dividing part comprises an upper outflow part and a lower inflowpart which are distributed up and down, the lower inflow part includes a plurality of lower dividing piers with fan-shaped cross sections, the multiple lower dividing piers are evenly arranged along the circumference, and a lower flow channel is formed between any two adjacent dividing piers; and the upper outflow part includes upper dividing piers with fan-shaped cross sections, the number of theupper dividing piers is equal to that of the lower dividing piers, the multiple upper dividing piers are evenly arranged along the circumference and are staggered from the lower dividing piers, eachupper dividing pier complet
