The technical result consists in increasing the energy efficiency of the wind, simplifying the design and improving reliability of the wind turbine, it is provided by the fact that the wind turbine comprising a shaft with attached to it traverses the suspension of the wings, according to the invention has a traction control wings and generator and wind wings hinged at the ends of the axes traverses at a point between the front edge of the wing and its center of pressure and connected with the swash windmill consisting of rings on the windmill shaft, connected by rods and hinges on the wing at a point between the wing center of pressure, and a rear edge, and the carriages on the ring swash, with the wind turbine comprises a ring machine, change the eccentricity of the ring relative to the shaft of the windmill.

DESCRIPTION OF THE INVENTION

The invention relates to wind power engineering, namely to a wind turbine with vertical axis of rotation.

Known rotor of wind turbine comprising a vertical shaft, the radial yoke, shaped rotary blade axial hinges and hinge axis in the circumferential direction are inclined in the same direction, and the shaft has a radius smaller than the distance from its axis to the proximal edge of each blade at any of positions of the latter ( cm. SU, 1645602 A1, cl. F 03 D 7/06, 30.04.1991).

The disadvantage of the proposed design is a small capacity rotor design complexity and low reliability when a sudden gust of wind because of the large number of moving parts unprotected.

Known wind turbine comprising a wind wheel disposed behind the head with blades mounted on a shaft with the possibility of deviation from the plane of propeller rotation under the action of wind and provided with a synchronizing mechanism sprung sleeves. Moreover blades combined into two symmetrical relative to the center plane group, each of which is provided with a semicircle and is pivotally connected with the thrust blades are mounted on a common shaft through the motor and the hinge mechanism is provided with a start and stop.

The disadvantage is poor reliability, and design complexity.

Known wind turbine comprising a shaft with attached to it traverses wings suspension (see. RU, 2042044 C1, cl. The F 03 D 3/00, 20.08.1995), taken as a prototype.

Disadvantages are the low reliability of the windmill in case of sudden changes in wind speed, design complexity, and the inability to modify a torque on the generator shaft if required.

The technical result consists in increasing the energy efficiency of the wind, simplify design and improve wind turbine reliability (windmill) is ensured by the fact that the wind turbine comprising a shaft with attached to it traverses the suspension of the wings, according to the invention has a traction control wings and a generator, and the wings windmill hinged at the ends of the axes traverse at the point between the front edge of the wing and the center of pressure and connected with the swash windmill, consisting of a ring on the shaft of the wind turbine, connected by rods and hinges on the wing at a point between the wing center of pressure and its trailing edge, and the carriages ring on the swash plate, and the wind turbine comprises a ring machine, change the eccentricity of the ring relative to the shaft of the windmill.

swash drive wind turbine further comprises a rocker for a bunch of wing rods to the swash ring, the ring swash plate hung on the windmill shaft to vary the angle of inclination to him, and the height of the position on the shaft.

Traverses wings suspension has a pivot axis on the flange windmill.

Traction swash linked to traverse intermediate rods for synchronizing the movement of the shaft around the windmill.

Flange planted on the shaft wind turbine, which has a thread, and the swash ring windmill is located above the flange suspension traverse wings.

FIG. 1 shows a general view of a windmill with wings in a working position and a generator.

FIG. 2 - wind turbine with a machine ring, change the eccentricity of the ring relative to the shaft of the windmill.

FIG. 3 - wind turbine (general view) with additional rockers and generator.

Turbine includes wing 1, the shaft 2, yoke 3 suspension of the wings 1, the hinge 4 suspension hinge 5 of the wing 1 and the rod 9, the carriage 6, the swash ring 7, drive 8 of the ring 7, traction 9, control wings 1 and the generator 10, and ring 7 machine drive 8, changing the eccentricity of the ring 7 relative to the shaft 2 windmill, change the angles of the wing 1 at different values ​​and thus affect the value of windmill power.

Traverses 3 suspension wing 1 has a pivot axis on the flange 11 of the shaft 2 windmill.

Drive 8 skew windmill machine further comprises a rocker arm 12 for connection rods 9 wing 1 with the swash ring 7, with 7 warping machine ring hung on the windmill shaft 2 with the ability to change the angle of inclination thereto and the height position of the shaft 2.

Flange 11 planted on the shaft 2 wind turbine having a thread 13 and a hinge 14 suspension. For support on the ground it is a windmill farm 15.

Wind turbine operates as follows. Wind acting on the wings 1, brings them into rotation which is transferred via the suspension traverse wings 3 1 via hinges 4 on rods 9 and further to the windmill shaft 2.

Wings 1 associated with the drive swash plate 8 through a windmill rod 9 and the carriage 6. The automatic skew by changing the eccentricity of the ring 7, the installation angle varies wing 1 towards the wind, namely, an increase in the magnitude of the eccentricity of the shaft 2 relative to the windmill wings 1 being a upwind deployed downstream a certain angle, resulting in rotation of the shaft 2, connected to the generator 10, and thus one windmill wings made converting rotational mechanical energy to electrical energy generated by the electric generator 10, which goes to the consumer. In the case when the wings are installed along flow 1, i.e. when the angle of incidence is equal to 0, a wind turbine works and thus it is protected against overloads and sudden wind gusts.

On the shaft 2 windmill planted flange 11 via a thread 13. In the case of sudden changes in wind power flange 11 moves along the threads 13 up, changing the angle of attack of the wings 1 windmill and decreasing torque. In the reverse movement of the flange 11 down torque increases.
