DESCRIPTION OF THE INVENTION
The invention relates to wind energy, namely to devices that convert the energy of the air flow into rotational motion transmitted to an electric generator.
An air flow energy converter (wind power plant) containing large diameter disks, blades (propellers), a central shaft (shaft), bearings and supports is known (see, for example, RU 2107836 C1, class F 03 D 5/00, 27.03. 1998, FIG. 1), on a set of essential features adopted for the closest analogue of the invention (prototype).
Disadvantages of the energy converter are low efficiency and low power of the installation due to low efficiency of conversion by wind power propellers.
The technical result of increasing the efficiency and power of the converter is provided by the fact that the air flow energy converter comprising large diameter disks, blades, the central axis, bearings and supports according to the invention further comprises large movable gears, a small central fixed gear, Gears and chain transmission, and the disks, on which the blade axes have blades, are rigidly fixed on the central axis.
At the end axes of the blades, on the outer side of the discs, stellate gears are tightly fixed, connected by a chain drive with star gears located on large movable gears.
Large moving gears engage with a small central stationary gear.
The large moving gears, with the rotation of the discs, run around the small central stationary gear half of its circumference and, with the help of star gears and chain transmission, automatically position the blades under some optimal angle of attack to the incoming air flow.

FIG. 2 is a flow energy converter, a front view
The air flow energy converter comprises large diameter disks 2 rigidly fixed on the central movable axis 3. Between the disks 2 are located blades 5 having end axes 6 rotating in bearings 7 located in the holes in the disks 2. At the end axes 6 the star gears 11 located on the outer side of the discs 2. On the outer side of the discs 2, large gears 8 are movably attached which engage a small central fixed gear 9 rigidly connected to the hub 10. The central axis 3 rotates in the bearings 4 located in the bushings 10, Located at the top of the supports 1. These supports are only two. On the large movable gears 8, stellate gears 13 are rigidly fixed, by means of a chain drive 12 interconnected with the star gears 11 on the end axes 6 of the blades 5. The large movable gears 8 have a diameter twice that of the small central fixed gear 9 and, with the rotation of the disks 2, This small fixed gear 9 is half its circumference, and by means of a chain transmission 11-12-13, rotation is transmitted to the blades 5, automatically positioning them at each moment of rotation at a certain optimal angle of attack against the incoming air flow. The blades 5 are straight, therefore the incoming air flow affects them all along the plane in the same way.
At the ends of the central movable axis 3, on the outer side of the supports 1, pulleys 14 are fixed rigidly, which by means of a wedge-rod 15 transmit the rotational movement of the central axis 3 to the pulley of the electric current generator 16.
The air flow energy converter operates as follows.
The air stream runs frontward on the blade 5 on the right or on the left. The lower part of the blade 5 is parallel to the air flow and flows around from above and below without resistance. Other blades 5 are positioned at a certain angle of attack to the air flow and the higher the blades 5 are located on the disks 2, the greater the angle of attack they have with respect to the air flow, the upper blade 5 has an angle of attack of 90 ° , i.e. perpendicular to the air flow. This is achieved by the fact that the large movable gears 8 rigidly connected to the blades 5 through the chain transmission 11-12-13, whilst rotating the disc 2 to the small central fixed gear 9, automatically position the blades 5 at some optimal angle of attack relative to the air flow. Gears 8 make a complete revolution around the small gear 9 half of its circumference.
Turning the blades 5 by means of the kinematic connection 8-9-11-12-13 leads to rotation of the central movable axis 3 which, by means of pulleys 14 and the vane belt 15, transmits rotational motion to the pulley of the electric generator 16 where the received electric power is transmitted to the consumers.
