The invention relates to the field of wind energy, namely wind turbine that converts the energy of the air flow into mechanical energy supplied to the generator. The technical result is to increase the efficiency (coefficient of performance), installation and simplifying its construction. Wind vortex type contains a tower, intake, vzducholod and rotational work body provided with the generator. While the tower is made adjustable in the direction of the wind, work the body in the form of a parallel set of cylindrical rotors so that a plane passing through the axis of rotation is parallel to the plane of the entrance cross-section of the inlet tangential type, made in the form of two symmetrical channels, moving in a spiral vozduhootvod and vzducholod tower communicated with the inside of both rotors and performed outside on the back side of the tower in the area of low pressure air through the venting channels. 14 C.p. f-crystals, 5 Il.

The proposed technical solution relates to wind energy, but rather to the wind is Kirovenergo.

Known bladed wind turbines, in which three or more horizontal vane rotor is located on a high pedestal, with the possibility of self rotation) to the wind and kinematic shaft connected to a generator [1] is similar.

Installation of this type have found wide application in areas with high wind speeds and successfully operate at wind speeds of 8 m/s and more.

At low wind speeds, for example, 3-4 m/s, these installation virtually ineffective, while the demand for wind turbines, successfully operating at low speeds, particularly for continental land areas, where such wind speeds are predominant.

More efficient at low speeds the wind turbine vortex type, containing a tower with intake, exhaust and rotational working body, located in the channel of air movement through the tower and communicated with the consumer of mechanical energy, for example, the generator [2] is a prototype.

The prototype has a complex structure, has great resistance naticoidea the air flow with a small working surface of the intake in relation to the total surface of the tower, which generally does not provide enough space for large quantities is given to the consumer. This leads to an increase in the overall dimensions of the tower, the emergence of difficult to explain to the supports overturning moment, a significant worsening of the whole structure and in General - to a significant under-utilization of energy of the air flow, notcause the tower. The passage of the air flow on the vertical axis of the tower is spent extra energy as due to the high friction surface of the inner long axis of the tower of operating channels, and due to the hydrodynamic imperfections rotational working body. The result is applied to the working body energy is significantly less than the energy of the air flow, notcause to the tower.

In the described technical solution, the said drawbacks are eliminated due to the fact that the tower is made adjustable in the direction of the wind, work the body in the form of parallel cylindrical installed interacting rotors so that a plane passing through the axis of rotation is parallel to the plane of the entrance cross-section of the inlet tangential type, made in the form of two symmetrical channels, moving in a spiral located on the periphery of the rotors vozduhootvod with protivopul is in and done outside on the back towards the intake side of the tower in the area of low pressure air through the venting channels; the venting channel of the internal cavity of the rotor with the exhaust in the form of channels rounded cross-section with a gradual increase in the area of this cross section in the direction of the outlet cross section of the exhaust; in the venting channel of the internal cavity of each rotor exhaust is additional at least one blade system; the rotor and the additional blade system is made as a single working body with a common shaft; vzducholod hydraulically communicated with the inner cavity of the rotor through the venting channels located in the ends of the rotors; vzducholod hydraulically communicated with the inner cavity of each of the rotor through the venting channels located in the Central part of the rotor; the air intake is provided with opposed spaced rotary intake plates, the axis of rotation which is fixed to the body of the tower and installed complanare axes of rotation of the rotors and symmetrically them; the axis of rotation of the rotors are complanare the axis of rotation of the tower; the axis of rotation of the rotors are arranged horizontally and the axis of rotation of the tower vertically; the shafts of the rotors are kinematically connected to each other and at least one electrogeneration electricity through the rotary manifold, mounted on the pivot axis of the tower; the tower is designed in the form of separate height sections with the possibility of installation on each other; the tower is set on the rotary platform and provided with a reversible drive you install it on the wind; a tower mounted on a rotary axis and provided with a rigidly associated remote interacting with the wind flow keel bring the towers in the wind; at the output of the exhaust installed additional deflecting the flow from the tower fairings.

In Fig.1-5 are examples of implementation of the proposed technical solutions wind turbines.

Wind turbine according to Fig.1, 2 consists of a swivel in the direction of the wind tower 1, located, for example, on the base plate 2 of the roof of the building, with the possibility of rotation of the reversible drive bring on the wind, comprising a motor-reducer 3, a reversing sensor wind direction, made, for example, like a weather vane in the form of the rotary plate 4, see Fig.2 interacting with the deviation of the wind from the axis of the tangential inlet type 5 with end switches 6 and 7 associated with reversing starter gear motor 3.

In the communication channel of the air intake 5, rolling in a spiral, located on the periphery of the rotors 9, plant in close proximity to each other and interacting rotational working bodies - cylindrical rotors 9, kinematically connected to the shaft of the generator 10 mechanical transmission 11. The rotor can be equipped with independent generators. When installing generators 10 directly in the rotating tower 1 electrical connection with an external electrical system can be carried out by any known method, for example, by electroconductor 20, the body of which is fixed on the base, and its rotary element mounted on the axis of rotation of the tower. The rotor 9 of snobunny installed on the periphery of the blades 12 forming an annular vane system on the entire surface of the rotor. The rotors 9 are set so that the plane passing through the axis 13 of rotation that is parallel to the plane of the entrance cross-section of the inlet 5, which in turn is made in the form of two symmetrical tangential channels adjacent to the peripheral surface of the tower 1, slowly turning into a spiral located on the periphery of the rotor ducts 14 are opposite to each other with Zakrytoe wind flow.

Vzducholod 8 communicated with the inner cavity of the two rotors 9 through the discharge channels 15, made of rounded cross-section area gradually uvelichivajushejsja the ends of the rotor 9. Vzducholod 8 performed outside on the back towards the inlet 5 side of the tower 1 in the area of low air pressure that is formed by wrapping the tower of the wind flow. To provide a tear-off thread for the tower and expansion thereby zone vacuum tower, i.e., to increase the vacuum at the outlet of the exhaust 8 it can be provided for deflecting the flow from tower 1 fairing 16, mainly providing spin going around the tower flow in the direction of circulation of the flow coming out of the exhaust 8.

Variants of the inlet 5 may be provided with opposed spaced air intake plate 17, which may be associated with the synchronization mechanism and the angular displacement (in the drawing shown) for regulating the position of the plates and change the flow inlet cross section of the air intake 5.

Control the size of the living section of the inlet 5, the purpose of the changes applied to the rotors 9 wind energy, may be necessary when significant changes in weather conditions and wind speed, which can be operated manually via the synchronization mechanism of the plates 17 or automatically.

Axis 18 stand them.

In the embodiment according to Fig.3 vzducholod 8 communicated with the inner space of the rotor 9 through the venting channels 15, made in the Central part of the rotor 9 to which each of the rotor is made in the form of two installed offset from each other sections, arranged on a common axis 13.

At the same time to reduce the height of the tower kinematic relationship of the rotors between itself and the generator can be performed through the middle part of the rotor by means of mechanical transmission 19, and the power generator 10 can be installed in the shroud fairing 21 (see Fig.2) located in the middle part of the inlet 5. The generator 10 may also be installed in the cavity of the base plate 2 tower 1, which may also be mechanical transmission 11 (see Fig.4) for synchronization of the rotors 9 electrogenerators 10.

To improve efficiency especially at low speeds the air flow of the internal cavity of each rotor can be communicated with the exhaust 8 through installed in the venting channels 15 additional vane impellers 22, mechanically or electrically connected with the energy consumer. Working extra wheel in the same way may be ationale to simplify the design of wind turbine rotor 9 and additional impellers 22 to perform as a single working body, having shared his shaft 13, see Fig.4. Here additional impeller 22 is installed with the peripheral ends of the rotors 9 and enter the appropriate venting channels, forming at its output common output channel exhaust 8, in the output section which also have an extra impeller 23. However arising rotors stream will be available on the output of the 8 exhaust through said additional vane impellers 22 and 23, which in General will significantly increase the energy transmitted to the generators from passing through the tower air flow, especially at low wind speeds of 2-4 m/S.

In Fig.5 shows a variant of the rotation of the tower 1 through imposed on the air flow from the back side of the tower 1 special fin 24 that when the wind farm on small power eliminates the need for a special drive mechanism, shown in the variants according to Fig.1,3,4. Here additional impeller 22 is installed with the ends of the rotors 9 are directly input channels 15 and is not mechanically connected with the rotors. Impeller 22 Autonomous bring additional generators 10.

Possible designs of wind turbines when axis 1 is blowing.

During wind tower 1 is set by means of the drive 3 or fin 24 on the wind and the air flow enters the inlet section of tangential inlet 5 and then enters the spiral vozduhootvod 14, across the peripheral surface of the fitting main blade system of the rotors 9, and then interacting with the blades 12, flows through them in the inner cavity of the rotor, transferring their energy to the rotor. Next, the air stream flows through the venting channel 15 to the exhaust 8 and flows outside from the rear side of the tower 1, the area of low pressure, which there takes place due to the organized through the fairing 16 separated flow past the body of the tower. When this wind flow has a direct impact on impeller system of the working body. This effect is enhanced by organized by the geometry of the tower is a significant pressure drop between the inlet cross section of the inlet 5 and outlet cross section of the exhaust 8, which leads to the increase in the speed of rotation of the rotors and increase their energy efficiency.

During the flow of the air flow through the tower through the tangential inlet and the vortex movement of air around the rotors and the venting rounded is(which increases the mass passing through the tower air by minimizing friction losses on the walls and inlet at the center of a vortex flow of low pressure from the back side of the tower directly into the internal cavity of the rotor), and it provides the most complete interaction of the air with a flow system of the rotors, with the most simple (flat) and effective configuration of the blades. To reduce energy loss also contributes to the relative positions of the rotors in their immediate proximity to each other, because at the site of their interaction, there is no surface, leading to inhibition of the wind flow, and also an extra twist, as coming out of the exhaust and ambient tower of threads.

Additional interaction of the wind flow with the working body is through the use of an additional blade wheel 22, which is especially important at low wind speeds. This also significantly increases the efficiency of wind turbines in the range of wind speeds from very low to medium.

For a given geometry of the turbine inlet cross section of the inlet is equal to the cross section of the tower or even exceeds it, which significantly improves entering the rotors of wind energy 1 m2the cross-section of the tower, which in this case takes the minimum possible dimensions and has the form most convenient for the installation of wind turbines on the in the form of a vortex flow contributes to a more complete “entry” notcause flow directly into the working bodies and the decrease in the proportion appropriate to the tower of flow, going around the tower without passing through the working bodies.

This effect contributes to efficient installation in a wide range of wind speeds and increases the total number of generated electricity per 1 m2the cross-section of turbine.
