FIELD: power engineering.
SUBSTANCE: hydroelectric plant for power generation comprises a block of blade screws 6 of axial type placed inside a body 7 and a nozzle. Screws 6 transmit rotation by geared wheels directly, one screw 6 to another one. Screws 6, according to their principle of operation, are master, and when engaged with each other, they rotate in different directions. The nozzle is made with a mixing chamber and is located outside the body 7 to provide for suction of the output flow from the body 7, increasing number of rotations of screws 6. Front ends of the screws 6 are installed in sliding bearings, and the rear ones are placed in thrust sliding bearings of horizontal arrangement, resting on conic journals providing for alignment of screws 6 relative to the body 7. Screws 6 are made with right and left rotation.
EFFECT: provision of continuous operation of a hydroelectric plant.
