Abstract

The invention relates to wind power and allows an increase in wind turbine power and wind utilization. During operation, a wind turbine containing three blade propellers (VK) 1.7 and 8, one of which 1 is fixed on sleeve 2 placed on a horizontal shaft 3, transmits the rotation of VK 1, 7 and 8 to generator 4, with VK 1 placed between VKs 7 and 8 and rotates in the direction opposite to their rotation. The rotation gear is transmitted through a kinematic link, made in the form of a vertical power take-off shaft 11, located in the center of the tubular support 5, bevel gears 12-14, one of which 12 is fixed to the upper end of the power take-off shaft 11, is placed inside the swivel head 6, installed on support 5, and in contact with two other gears 13 and 14, having equal diameters and located opposite to each other, one of which is located on hub 2 of VK 1, and the second 14 - on horizontal shaft 3. With increasing speed and the actuator of the speed regulator, made in the form of an electromagnet 9, the windings of which are located on a sleeve 2 made of a non-magnetic material, induces, in a metal disk 10 mounted on a horizontal shaft 3, eddy currents, creating a moment opposite to the moment of VC rotation 1, 7 and 8 and results in the rotational speed of the VC 1, 7 and 8 to the given one. 1 hp ff, 1 ill.

Description

This invention relates to wind power and can be used in wind rotors,

The purpose of the invention is the powerful, wind and wind utilization factor.

The drawing shows a schematic wind turbine, a general view.

The wind turbine contains a blade wind wheel 1, mounted on the hub 2, placed on the horizontal shaft 3, kinematically connected with the generator 4, the executive body of the rotation speed regulator. In addition, the windrower contains a swivel head 6 mounted on a vertical tubular support 5, in which —the horizontal shaft 3 is located, two bladed propellers 7 and 8, placed on a horizontal shaft 3 with the possibility of rotation to the side, opposite to the rotation of the first wind wheel 1, the first wind wheel 1 is located between the additional wind wheels 7 and 8 and kinematically associated with them, and the actuator of the speed regulator is fulfilled in the form of an electromagnet 9, the windings of which are placed on the hub 2 first th wind wheel 1, made of non-magnetic material and a metal disk Yu mounted on a horizontal shaft 3 with the possibility of inductive interaction with the electromagnet 9,

The kinematic connection of the windwheels 1, 7 and 8 with the generator 4 is made in the form of a vertical power take-off shaft 11, located in the center of the tubular support 5, G2-14 bevel gears, one of which (12) is fixed on the upper end of the power take-off shaft 11, inside the swivel head 6 and is in contact with two other 5 and gear 13 and 14, having equal diameters and diametrically opposite one another, one of them (13). located on the hub 2 of the first wind wheel 1, and the second (14) - on the horizontal shaft 3.

The wind turbine works as follows.

Under the action of the wind, the wind wheel .1 and the additional wind wheel 7 and 8 rotate in opposite directions, since their blades are located at opposite angles to its direction. The rotation of the wind wheel 1 is transmitted

bevel gear 12 and power take-off shaft 11 through sleeve 2 and its bevel gear 13 simultaneously with the transmission of rotation to windwheels 7 and 8 and in the opposite direction through shaft 3 with gear 14, diametrically opposite to gear 13. Rotation of shaft through pair of bevel gears is transferred to generator shaft 4 installed at the bottom of the support.

When the wind speed increases, the electric speed regulator (not shown) supplies voltage to its executive body, an electromagnet 9, which induces eddy currents in the disk 10, which inhibit the opposite rotation of the sleeve 2 with the wind wheel 1 and the shaft 3 with the wind wheel 7 and 8 to a predetermined value.
