MINI-HYDROELECTRIC POWER PLANT Russian patent published in 2020 - IPC F03B13/00 F03B17/00 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, particularly, to mini-hydroelectric power stations. Mini-hydroelectric power plant includes cistern consisting of movably connected shell ring 2, cover and bottom 3, inner cavity, vertical shaft in the form of Archimedean screw connected by coupling with drive of electric generator 9 and kinematic pair 12 with bottom 3, gap 7, mounting units 13. Screw has two spiral blades 14 located symmetrically relative to its longitudinal axis. Inner cavity is space between screw and shell 2. Clearance 7 is distance between equidistant surfaces of shell 2 and space swept off by blades 14. Bottom end has shank making rotary kinematic pair 12 with bottom 3.

EFFECT: invention is aimed at improvement of efficiency and simplification of design of mini-hydroelectric power station.
