AUGER SMALL HYDROELECTRIC POWER STATION Russian patent published in 2021 - IPC F03B17/06 

FIELD: power industry.

SUBSTANCE: invention relates to damless hydroelectric power plants and is aimed to convert the energy of the hydraulic flow of small rivers and watercourses into electrical energy. The auger mini-hydroelectric power station contains two augers installed on the base 12 with opposite twist of spiral blades on their shafts 1, 2, a reducer, shaft 1 is connected to an electric generator 5. Shafts 1, 2 are located parallel to each other and directed along the axis of flow. Gears 3, 4 gearboxes are mounted on shafts 1, 2. Parallelograms are placed on the outside of each auger on the base 12, on the hinges 7 of which the blades 6, 10 are fixed, directing the flow to the auger blades, at an angle of 45 degrees for one auger and at an angle of 315 degrees relative to the flow axis for the other auger. Each parallelogram is equipped with a drive 9, 11 to change the angles of inclination of the blades 6, 10 guiding the flow. The auger blades are funnel-shaped.

EFFECT: invention is aimed at increasing the productivity of the system and the total power of the augers.
