WIND-DRIVEN POWER PLANT Russian patent published in 2019 - IPC F03D3/04 F03D3/06 

FIELD: power engineering.

SUBSTANCE: invention relates to the wind power engineering. Wind-driven power plant comprising a funnel made in the form of a truncated cone or a cylinder, changing into a truncated cone, and a rotor arranged thereon along its vertical axis, made in the form of a shaft with blades fixed on it by means of connecting discs with their partial protrusion from the lower part of the funnel, said funnel is mounted on supports with step-bearings, at least three, at the level of upper edge of the funnel end, in the horizontal plane, a power crosspiece rigidly connected to the flare, in the center of which there is a bearing unit, in which the rotor shaft is fixed with possibility of rotation, at the level of the lower part of the funnel supports in the horizontal plane, a power crosspiece rigidly connected to the supports by means of structural elements is installed, in the center of which there is a bearing unit, in which the rotor shaft is fixed with possibility of rotation, generator of EMF is installed on power crosspiece at the level of lower part of funnel supports in horizontal plane, at that rotor of EMF generator is rigidly connected to rotor shaft, at that cone-like helical blade with variable radius decreasing in direction from lower to upper edge of funnel end is fixed inside the funnel on the shaft above the blades with partial protrusion from lower part of the funnel.

EFFECT: invention is aimed at improvement of wind energy use efficiency.
