The invention relates to the field of wind energy, is intended for direct conversion of wind energy into thermal energy, and can be used in the heating systems of buildings, production facilities, mainly in the agricultural sector, as well as in technological purposes (heating and drying materials and others).

There are many types of wind turbines that use different principles of transformation of mechanical energy into thermal - hydrodynamic, compression and other

Known, for example, wind power plant for heat production in A.S. No. 1346848, CL F 03 D 9/00. The system includes a wind wheel fixed on the shaft of her power transmission impeller of the water pump and hydraulically associated turbine wheel mounted on a shaft of the electric generator.

Also known thermal wind (see a.c. No. 1701976, CL F 03 D 9/00)containing a wind-wheel, gearbox and two-stage piston compressor.

The main disadvantages of the described plants are complex power transmission, low dynamic performance and instability in a wide range of wind loads due to the lack of stabilization of the frequency of rotation of the propeller due to poor load characteristics applied to change the oil energy. Moreover, they are not suitable for the simultaneous ventilation of the heated space and maintain a constant temperature without additional hardware.

As a prototype adopted by thermal wind (see A.S. No. 1064039, CL F 03 D 9/00), including a wind turbine with axial propeller connected to the vertical power transmission via angular magnetic transfer. The shaft is connected with the hydrodynamic heat generator input is set to the egalitarian nutrient reservoir, a temperature controller with a controllable valve.

The disadvantages of this setup are also the complexity of power transmission, permanent changes to the frequency of rotation of the wind turbine from zero to the limit due to the mismatch between the characteristics of primary (wind wheel) and secondary (heat) energy converters, which reduces the dynamic quality and sustainability. In addition, the heating of the building during the use of such systems is impossible without radiators, convectors, registers, and similar local heat exchangers, and to maintain the coolant temperature within the specified limits or the implementation of the ventilation of the heated space is also required additional technical means.

Object of the invention is reduced is the cost of production and operation of wind turbines by simplifying their design, improving the sustainability of their work in a wide range of wind loads for optimal dynamic mode, providing protection from harmful vibrations and frequency of rotation of the propeller, as well as providing the possibility of their use for heating and cooling a stream of pure air with a constant temperature without the use of additional hardware.

The problem is solved in that in verateplaja unit (WTU), containing wheel with rotary blades, heater, inlet and outlet nozzles, according to the invention the heat source is made of frictional conical drum with a ribbed outer surface of the rotor is installed with a wind turbine on a common shaft, with the possibility of axial movement, friction linings, still planted on the rotor, and a heat exchanger formed by the ribbed surface of the drum and adjacent the shell, while the heat exchanger is equipped with a suction inlet - air vent, open in the direction of the larger end of the drum, and the outlet pipe - manifold, in addition, propeller blades provided with offset in the lateral direction of the axes containing the levers associated with the actuator by means of a separate rod, the synchronizing sleeve and the total thrust made with one-sided emphasis, while ry is equipped with AGI stops and related goods forming a protection device according to the parameters of speed and vibration of the propeller.

Performing friction heat generator in the form of a conical drum with a ribbed outer surface, forming together with the sheath replaoement, and rotor with friction lining mounted on movable in the axial direction of the shaft of the propeller, allows to obtain the optimal load characteristic of the heat source, thereby to ensure proper installation in a wide range of wind loads and also to simplify the design by eliminating complex power transmission.

The axes of the blades are offset in the lateral direction gives the blades the property of the vane is installed in the position of least resistance to the impact of the air environment that provides resistance WUT in its disabled state when almost any storm conditions.

The application in the drive device of blades total thrust with one-sided emphasis improves the dynamics of the wind turbine in operation, reducing its brake downs wind due to the ability of the blades to samoustraniajutsia in the position of least resistance to rotation by inertia while dumping the load on the rotor of the generator due to the lack of sailing force, clamping its frictional nakladka the mirror drum in any other mode WUT.

Equipment actuating levers located on the axes of the blades, lugs and individual rods associated synchronizing sleeve and the total thrust with the drive allows you quickly enable or disable the installation and related emphasises the goods constitute a safety device to disable WUT by breeding stops under the action of inertial or centrifugal forces when dangerous vibrations and excessive frequency of rotation of the propeller.

Execution of the input pipe of the heat exchanger in the form of intake, the open side of the larger end of the drum, facing the wind at the windward side, allows the use of atmospheric air as a coolant and to ensure consistency of its temperature, because the value of its flow and the intensity of the heat, have a direct dependence on the same parameter - force wind pressure, as well as carry out together with space heating their supply ventilation without additional fans, local heat exchangers and temperature controls.

Patterned design with friction linings in the form of package sections allows the economical use of expensive materials made from synthetic resins, rubbers, carbon composites, and others, as when maximum wear pads in each cycle of use, appropriate to otstoyam the maximum displacement of the shaft with the rotor - the thickness of the section, instead of replacing all the pads can be replaced only one, extremely worn her section on a new set on the other side of the package.

1 shows a General view of verateplaja installation; figure 2 - node a in figure 1; figure 3 - the node B in figure 1; figure 4 is a view D figure 3.

Vitrually system includes a wind wheel 1 with rotary blades 2 and the hollow shaft 3, the friction heat generator 4 mounted on a rotary device 5 of the support structure 6. The heat source 4 consists of a friction drum 7 with a ribbed outer surface, forming together with the adjacent shell 8 heat exchanger 9 to the inlet side view air intake 10, open in the direction of the larger end of the drum 7, and the outlet pipe in the form of a collector 11, associated with the external thermal line through the channel in a rotary device 5, and the rotor 12, which is located inside the drum 7. The rotor 12 is mounted on the shaft 3, are equipped with a still planted on his friction lining 13 and closed Radome 14. The shaft 3 is mounted on bearings 15 of the bearing sleeve 16 with the possibility of a limited axial movement. The blade 2 has shifted in the lateral direction of the axis 17, containing the levers 18, associated with the actuator 19 by means of a separate rod 20 and the synchronizing sleeve 21, which is located behind the the PR-22 total thrust 23 within the hollow shaft 3. The levers 18 is movable in a direction parallel to axis 17, is installed lugs 24 and associated cargo 25, fitted with coil springs 26, previously tucked up efforts to counter the inertial and centrifugal forces acting on the lugs 24 in the normal mode WUT.

The outer surface of the heat exchanger is thermally insulated 27.

Vitrually installation operates as follows.

Installation can be in one of two States: disabled, when the blade 2 of the wind turbine 1 are mounted on their axes 17 in the feathered position, without creating substantial torque, and included, in which the blades are rotated into position on the corner αdetermined by calculation for each model WUT.

Enable installation of the actuator 19, the total thrust 23, moving in the direction of the Radome 14, my emphasis 22 removes the synchronizing sleeve 21 on the interval L, turning the associated rods 20 of the lever 18 at a specified angle αwhere the ledges lugs 24 will coincide and under the action of the springs 26 will be closed, after which the rod 23 is returned to its original position. The lugs 24 does not allow the lever to return to its original position, but do not prevent further free rotation together with the axes 17 and the blades 2 within the additional angle δ with the corresponding the Odom synchronizing sleeve within the interval Δ L.

Wind flow affects the wind wheel 1, creating torque and axial force - sailing force of the wind wheel, which moves with the shaft 3, mounted with axial mobility on the bearings 15 of the bearing sleeve 16, and with it the rotor 12, compressing the friction pad 13 to the mirror drum 7, which is heated by friction, gives off heat through its ribbed surface of the stream of air blowing wind pressure through the inlet 10 and flowing through the collector 11 and the channel in a rotary device 5 of the support structure 6 in the duct. If the force of the wind changing sailing the force of the wind wheel 1 is transmitted to the rotor 12, the pressure contact of the rubbing bodies and, consequently, the friction force changes in proportion to the wind pressure that corresponds to a change in torque on the wind turbine 1, so the frequency of rotation of the latter varies slightly. The power generator 4 is also changed, but not so much by changing the angular velocity of the rotor 12 as due to the change of the friction force. When recessions same wind sailing the power of the wind turbine 1 is falling, reducing down to zero pressure pads 13 on the mirror drum 7 and the blades 2 self-aligning in the position of least resistance to rotation, resulting in a braking of the wind turbine 1, the rotating inertia, minimalist guest is Ino, and dynamic properties WUT improve. With the resumption of the wind blade 2 again assumes its working position, the rotor 12 with the cover plate 13 is tightened to the mirror drum and installation takes the load.

The amount of flow of the atmospheric air, breakable pressure of the wind through the heat exchanger 9, is changing as the power generator 4, which determines the intensity of heating of the heat carrier, in direct dependence on wind power, which stabilizes the temperature of the coolant. However, heat loss through the shell 8 of the heat exchanger 9 are prevented its insulation 27.

If any dangerous vibrations or increasing the speed of the wind turbine 1 from outrageous wind loads or as a result of a malfunction WUT, for example, a full deterioration of the friction lining 13, the setting is disabled security: this cargo 25 under the action of inertial or centrifugal force overcomes the resistance of spring 26, to throw the lugs 24 and the blades 2 are transferred in off - feathered position.

Line disconnection WUT is carried out by the actuator 19 by moving the thrust of 23 from the reference position in the direction of the levers 18, its conical end of breeds lugs 24 and the blades 2 are transferred in the feathered position.

The advantages claimed in comparison with the prototype that is achieved by reducing the s the cost of its manufacture and operation by simplifying the design, improving the reliability and stability of operation in a wide range of wind loads by equipping heat generator with optimal load characteristic, providing heating and cooling to maintain a constant temperature without the use of additional technical equipment at an economical consumption of the replaceable friction material due to the performance of the lining of the rotor dial version.
