PORTABLE WIND GENERATOR Russian patent published in 2021 - IPC F03D7/06 

FIELD: portable wind generator.

SUBSTANCE: invention relates to a portable wind generator. The wind generator contains a blade turbine 1 with a vertical axis of rotation 2, located inside the air guide apparatus, and an electric generator 21, mounted along the axis 2. The device is made in the form of wind guiding screens evenly distributed around the circumference. The lower edges of the screens are connected to the lower cover 7, and the upper edges to the upper cover 8, forming the air chambers of the nozzle. The screens are equipped with vertical swivel plates. The turbine 1 consists of parallel disks 22, fastened by axial holes to the rotary shaft 23 and forming a hollow drum, and rigidly fixed between the inner surface of the disks 22 of vertical blades in the form of unwinding spirals in the direction opposite to rotation. Bearing elements 32, 33 are installed between the covers 7, 8. The ends of the plates farthest with respect to the axis 2 are connected with the elements 32, 33 by means of hinges. On the cover 7 and / or cover 8 there are limiters for the angle of rotation of the plates. The plates are unilaterally pressed against the stops. Elements 32, 33 are connected to covers 7, 8 and form the frame of the apparatus.

EFFECT: ensuring efficient conversion of kinetic wind energy into electrical energy.
