HYDROTURBINE Russian patent published in 2018 - IPC F03B3/04 F03B3/14 F03B17/06 

FIELD: hydropower.

SUBSTANCE: invention relates to hydropower and is intended for converting the energy of river water flows into electrical energy. Hydroturbine includes blades 1 fixed from two ends, one of which is fixed to shaft 6, two ring sets 3, 4 with different diameters selected depending on the condition that one part enters into another which are congruently mounted relative to each other. On the inner surface of nozzle 3 of smaller diameter pins 2 are rigidly fixed, on each of which one of blades 1 mounted on shaft 6 located inside nozzle 3 is pivotally fixed about its longitudinal axis. On each of blades 1, which are articulated inside nozzle 3, on the line of intersection of the plane of the end of this blade 1, opposite to the end fixed to shaft 6, with the plane of the trailing edge of same blade 1, pin 5 rigidly connected to a hinge rigidly mounted on inner surface of nozzle 4 of a larger diameter.

EFFECT: invention is aimed at obtaining the maximum efficiency while increasing the range of performance characteristics in the water flow due to a change in the angle of blade installation.
