The invention relates to wind power generation, namely to small power stations, and can be used in rural areas. The technical result consists in the creation of a reliable wind power plant and is achieved by the fact that a wind turbine comprising a tower, a single-tier windmill with a vertical axis of rotation, a generator, ejectors with built-in fans, consisting of guide funnels connected to the internal cavity of the tower and directed to the blades of the windmill, Which rotates two wind currents, has an air accumulator, a second generator and a shaft, both of which are located in the tower and connected to the windmill by means of a high-speed electromagnetic gear, while the second generator is connected to the drive via an electromagnetic clutch of the clutch, and the start of the generators is via a reducer . On the roof of the tower there is a weather vane, which regulates the work of the ejectors. The windmill is put on the generator stator with a gap, the generator drive is located inside, and the ejectors and air accumulator are outside the tower.
DESCRIPTION OF THE INVENTION
The invention relates to wind power and can be widely used in all regions of the country as a small power station.
A wind turbine is known, comprising a rotor mounted on the base of a tower in the form of two blades arranged in one another and two tiers of arms mounted on respective shafts with the possibility of rotation in different directions; the inner shaft is connected to the rotor of the generator; the outer shaft is connected to the stator, and the wind installation is equipped with two Cones in the upper part of the tower, installed coaxially from the two ends of the tiers of the blades and facing vertices one to the other; A bell - hub, between the side walls of which and the back wall is formed chamber; A tier installed between the tiers, each tier is provided with a fixed outer rim of the guide vanes, and in one of the tiers the blade blades of the wheel and the guiding device are oriented in one direction, and in the other - in different directions (see RU, 2028504 C1, 09.02.95, F 03 D 3/02).
The disadvantages of this installation are the low efficiency of the use of wind force and the cumbersome structure with the presence of a large tower height.
The closest to the invention is an installation comprising a tower, a single-tier windmill with a vertical axis of rotation, a generator and ejectors with built-in fans consisting of guide funnels connected to the interior of the tower and directed to the blades of the windmill. (See RU, 2105189 C1, 20.02.98, F 03 D 3/00).
The disadvantages of the known installation include the following: the absence of an air battery, and an open method for locating a wind turbine.
The object of the invention is to provide a reliable plant for the village.
This object is achieved in that a wind turbine comprising a tower, a single-tier windmill with a vertical axis of rotation, a generator and ejectors with built-in fans consisting of guide funnels connected to the interior of the tower and directed to the blades of the windmill, according to the invention, ; The first enters through the cones at the top of the tower, and the second through the ejectors, while the wind power plant contains an air accumulator, a second generator and a shaft; Both generators are located in the tower and connected to the wind motor using a high-speed electromagnetic gear, while the second generator is connected to the drive through the electromagnetic clutch of the clutch, the generator starts running through the reducer, and on the tower crash there is a weather vane regulating the operation of the ejectors. The windmill is put on the stator of the generator with a gap. The generator drive is located inside, and the ejectors and air accumulator are outside the tower.
The technical result which can be obtained by the implementation of the invention in increasing the power of the wind farm and ensuring the reliability of the structure as a whole.
The invention is illustrated by the following figures: FIG. 1 is a general view of the wind farm, FIG. 2 - two-speed reducer, which allows to mount the wind turbine directly on the generator drive shaft.

FIG. 3 - electromagnetic drive, The wind farm contains a tower 2 mounted on the base 1, with cones 3-4 in its upper part, rotors 5, 6. In the first level there is a wind turbine 7, in the middle part of which there is installed a reducer 8 with electromagnetic coupling, and in the lower part there is an annular railroad 9. |

Two rotors are connected by a vertical shaft 10, inside the tower 2 there are generators: upper 11, lower 12.
At the base of the tower 2, inside, there is a computer room 13, and from the outside, along the perimeter of the building, there are ejectors 14. Tower 2 has a shaft 15 with an air accumulator. The vertical shaft 10 connects the rotors 5 and 6 through the electromagnetic clutch 16. At the top of the tower 2 are fixed guide vanes 17, a and airflow concentrators 18 for tightly coupling the cones 3 and 4.
On the roof of the tower 2 there is a weather vane 19 in the form of a funnel and regulating the operation of the ejectors 14.
Inside the ejectors 14, built-in direct-flow fans 20 are installed. When the wind turbine is in operation, two wind currents rotate: the first flows through the cones 3, 4 at the top of the tower 2 and the second flow 21 through the ejectors 14. Fits 22 of the funnel shape are installed on the intake side of the ejectors 14 And the line 23 from the air accumulator 15. The blades of the windmill 7 are supported from below by the rails of the road 9.
The working space of the blades is in the middle part of the cones 3, 4, and the exhaust air is discharged to the side opposite to the direction of the wind.
The upper generator 11 is started up when the electromagnetic gear 8 is activated, for example, a three-speed gearbox (see Figure 3). The lower generator 12 is started by turning on the electromagnetic clutch 16.
Such a sequential inclusion in the operation of generators contributes to an increase in the power of the wind farm.
