FOLDING WIND-DRIVEN POWER PLANT Russian patent published in 2019 - IPC F03D7/02 F03D13/20 

FIELD: power engineering.

SUBSTANCE: invention relates to the wind power engineering. Foldable wind-driven power plant includes a post with a wind generator in its upper part, which is fixed on the main support and is arranged with the possibility of inclination to the horizontal position and lifting into the vertical position, as well as the main winch. Plant is also equipped with auxiliary winch mounted on additional support with seat, made on separate foundation, wherein main support consists of fixed base and rotary part installed on it, made with possibility of rotation in horizontal plane around vertical axis, allowing to turn on wind fixed on rotary post, made in form of vertical wing, implemented based on spatial frame, elements of which work only for compression or stretching and coated with shell, and in section having the form of symmetric aerodynamic profile, wherein the vertical axis of rotation of the post is located before the aerodynamic focus of the wing, which enables the post to make a volatile wind, at that, in the lower part of the post there is a hinge of the turn of the pole around the horizontal axis, which divides the post into a non-rotary beam, having rope transfer units remote from the rotation axis, mounted on the fixed base, and inclined lifting part, which contains in lower part blocks of attachment of said ropes, located at a distance from said hinge, wherein in upper part of post there is a fixation point of auxiliary winch rope.

EFFECT: invention is aimed at reduction of weight of lifting part of wind-driven power plant with possibility of lifting and lowering mast without application of lifting cranes of high carrying capacity.
