DESCRIPTION OF THE INVENTION

The invention relates to wind power engineering and can be used for power generation including use-low power devices for supplying electric power through the voltage stabilizer for low energy consumer.

Known propeller (TSB, 1971, Vol. 5, p. 2662) consisting of a sleeve fixed on the shaft on which the fixed profiled radially arranged blades having different profiles along the span in cross section and variable angle to the plane profiles rotation - twist. This screw is suitable for receiving a wind turbine propeller wind flow energy. However, in this case it has a lower hydraulic efficiency, as the active portion for receiving a flow of wind energy is only part of the blade is located at a distance from its root, and the energy of the wind flow through the central part of its cross section is practically not used.

Known two-shaft propulsion system of the vessel (the USSR, the AS 846 395, IPC 63 H 5/14; 5/16; 1979) comprising two propellers synchronized on mutually opposite rotation, with profiled blades and placed in the head in one plane with mutual overlapping planes of rotation of the blades, the shafts of the screws are arranged in the same horizontal plane, and the blades of one propeller are placed in between adjacent rotor blades. However, the complex structure of the propeller is designed to operate in an aqueous environment and little use as an engine for use in an air environment as a device for receiving a wind turbine in the wind flow energy and converting its kinetic energy into rotational energy.

Known wind turbine (USSR AS N 1523711, IPC F 03 D 7/02, 1987), containing the blade propeller mounted one after another on a horizontal shaft, speed controller windwheels with the executive body of the regulator, and a generator, kinematically connected to the propeller via transmissions comprising a vertical shaft and a set of bevel gears. However, this wind turbine has a complicated design, especially the controller speed, running on friction slowdown windwheels, whereby part of the useful energy of the wind flow received by the propeller, useless dissipated as heat generated by friction in the retarding device, and themselves propeller continue with testing increased load.

The closest to the proposed device in its technical essence is vetroenergicheskaya installation (RF Patent N 2096656 IPC F 03 D 7/07; 5/00, 1997) containing the power support mounted thereon pivoting about a vertical axis with a head fixed to it one by one other on a horizontal shaft impeller blade rotor with shaped radial vanes kinematically coupled with one of the impellers consumer power and stop the rotation speed of impellers, comprising mounted on the swivel head a vertical fin mounted via respective knee-extension brackets aerodynamically balanced - the output keel - rudder and rudder on the trailing edge - trimmer, connected by rods to the imposition of outside management swirling vetropotokah frontal lobe to the wind at the end of a remote console, is pivotally mounted on a rotating head with deflection in the horizontal plane and a spring-loaded into the wind. However, this windmill somewhat lower energy capacity due to the fact that the impellers are arranged one after the other and capture the active part of the wind flow energy, the cross section of which has already blocked the front arranged wind wheel, and because the effectiveness of each of the impeller blades decreases towards the root of blades to zero and to increase the power of the wind power installation, you must either increase the diameter of the impeller, or their number, which complicates the installation workability and its practical use.

The object of the invention is to increase the cross-sectional area is helpful used wind flow when the stored amount diameter impellers to achieve a sufficient structural simplicity and increased hydraulic efficiency due to more efficient use of the kinetic energy of the wind flow, the technical result which is to increase the power and energy sector and increase its durability .

The essence of the invention is as follows.

Horizontal force frame is located above the upper plane of the rotary head and fixed therein by means of remote power struts and gear, at least part of them, and the screw blade may be made of caprolactam.

Novel features are the following features:

- Energy complex contains three cinematically linked propellers, two of which are located in front next to each other, and a third of them and addressed frontally against the wind, thereby increasing the power of the complex;

- Screw shafts are arranged in the same horizontal plane, thereby eliminated the increase in the vertical size of the active part of the complex and increase the diameter of the screw, contributes to the strength of the blades;

- Position the screws in the order when the two front screws are located next to the mutual overlapping planes propellers and tretyy behind them, preserved the vertical complex size and achieved a slight increase in cross-horizontal complex size while significantly increasing the efficiency of the use of wind flow energy, as more fully use it energy over the entire cross-section, including energy, inevitably spent on unnecessary twist wind flow situated in front propellers, and increasing hydraulic efficiency of the complex;

- Removal of the plane trees screws above the top horizontal plane of the rotating head provides a smooth and quiet overrunning the wind flow on the blade screws, maintains laminar oncoming wind flow, reduces the additional losses of its energy when possible zavihrivanii;

- Production of the gears and propeller blades of caprolactam improves the mechanical efficiency of the kinematic connection shaft and corrosion durability of the complex, working in an air atmosphere with its inevitable humidity.

Horizontal force frame located above the upper plane (20) and a rotary head mounted on it by means of remote power struts (21) and gear, at least part of them, and the screw blade may be made of caprolactam.

Energy complex three-shaft wind turbine operates as follows.

The wind flow is incident on the front of the blade screws located flows around them, and due to its kinetic energy, rotates them in opposite directions according to the orientation of the blade profiles. Despite the fact that the propeller rotation plane mutually overlap each other, it does not prevent the rotation of the screw as the blades of one propeller in rotation screws are synchronized to the same rotation speed, pass through gaps between the blades of the adjacent screw turn the blade of the screw for the blade neighboring than is achieved additional use of spin energy (drop) wind flow one of the screws on the rotation of the adjacent screw and partial straightening of the wind flow input to the rear rotor blade that is kinematically connected to the power consumer. Since all three screws kinematically linked together they work as a single vetrodvigatelny complex, more completely and efficiently using the kinetic energy of the wind flow across its cross-section.

At the same time the wind stream passing through the rotor blades, flows around the keel, the wind directing complex. In the case where the wind force is exceeded, the command paddle is deflected towards the wind deflecting rudder trim, which in turn deflects the rudder, thereby rotated by a certain angle swivel head, all in conjunction with screws complex. Screws several "turn away" from the wind, while continuing to rotate with the same speed and thus reduce the possibility of power load on the blades when the wind strengthening and smoothing uneven screw rotation speed in gusty winds.

The proposed invention allows to create complex three-shaft wind turbine energy, is relatively simple in design, with high capacity, hydraulic efficiency and durability with reduced scope of the blades and the cross sectional area of ​​the wind flow used rationally usable during operation slabomoschnyh consumers.
