DESCRIPTION OF THE INVENTION
And zobretenie relates to wind energy and can be used to create new types of stationary and transportable wind turbines. Known wind turbine comprising a vertical shaft equipped with the satellite units containing vertical rotary blades, axes are connected to gears, platform and vane associated with the bracket provided with contact groups (RU 2050466 C1, F 03 D 7/06, 20.12.1995).
The disadvantage of this wind turbine is low efficiency and increased sail wind turbine at high wind speeds, and low reliability due to the use of blades, mounted at one end.
Known wind turbine comprising a horizontal shaft equipped with the satellite unit comprising rotary blades, the axis of which have two points of support and connected to gears and comprises a platform and a vane associated with the bracket, provided with contact groups (RU 2190123 C2, F 03 D 7/06 , 27.09.2002).
The disadvantage of this wind turbine is the presence of the central cam mounted inside the enclosure, which complicates the manufacture of the wind turbine, but also its maintenance and repair.
The technical result is to use a maximum of wind flow energy efficiency in the widest possible range of wind speeds (up to Burevoi) with maximum possible simplicity of design, improving the efficiency of the wind turbine and its reliability and manufacturability during manufacturing, but also in the operation and ensured by the fact that a wind turbine comprising a non-rotating central axis mounted horizontally, with a central gear made conical, satellite links, disposed around the central gear radially and uniformly, with the roller of each of the satellite link with bevel gears at the ends is formed in one unit, one end of the roller associated with the central gear, the vane gear comprising a large and small cylindrical gears with large cylindrical gear paddle gear interacts with a low and fixed on the blade axis aligned substantially horizontally, each vane ends of its axis rotatably supported on brackets, reinforced foundations for a cylindrical body mounted to the central axis coaxially rotatably and peaks at both ends of the central axle brackets connected to the annular rim, which are drive wheels which are connected flexible transmission energy converters, with the central axis of both ends rests with fixation on the frame, which are mounted on opposite sides of the platform, the center of which is installed vane, connected with an arm provided with contact groups, wherein the platform is located on the bogies mounted on the circular track, the center of which coincides with the platform axis of rotation, with the trolley comprise traction motors, and the central bevel gear rigidly mounted on one end of a non-rotating central axis and a cylindrical small vane gear reducer fortified fixedly and coaxially with a bevel gear cooperating with a bevel gear belonging to the satellite link and the roller facing the same blade of the satellite link. Moreover, wind turbine device comprises a flexible tension transmission, and is provided with a power pickup device.

Wind turbine provided with a rotor having rotatable around horizontally disposed non-rotating central axis 1. At one end of the center axis 1 set central bevel gear 2, and satellite links are located around radially and uniformly, evenly and thus, the roller 3 of each of the satellite link with conical gears 4 and 5 at the ends is formed in one unit. Bevel gear 5, belonging to the roller and facing in the direction of the blades 6 of the same level of the satellite, is in communication with a bevel gear 7, a fortified windmill for rigidly and coaxially with the small cylindrical gear 8 paddle gearbox. Large cylindrical gear wheel 9 interacts with a low and fixed on the blade shaft 6 mounted horizontally. Each blade 6 ends its axis rotatably supported on brackets 11, reinforced foundations for the cylindrical body 12 established relative to the central axis 1, coaxially rotatably and top brackets 11 at both ends of the center axis 1 are connected to the annular rim 13, which are drive wheels, flexible transmission 14 associated with the energy converter 15. The central axis 1 rests on both ends of the frame 16, which are mounted on opposite sides of the platform 17, the platform 19 is located on the bogies, and provided with a traction motors mounted on a circular track 20, the center of which coincides with the axis of rotation In the center of the platform 17. platform 17 is set vane 18, by which the control is performed on the wind orientation. Wind turbine comprising a flexible and apparatus for transmitting a tension and, in addition, provided with a power pickup device.
At full rotation of the rotor blade around its axis 6 make a half-turn, and the direction of rotation of the rotor blades opposite the direction of rotation. The ratio of gear teeth 2-4 (Z1-Z2), gears 5-7 (Z3-Z4) is 1: 1. The ratio of gear teeth 8-9 (Z5-Z6) is 1: 2, and the possible number of wind turbine blades is three, and the number is determined by the bevel gears, having the ability to interact with the central bevel gear 2. The design of a wind turbine with a lot of teeth ratio of the number of blades above par gear changes while maintaining the overall gear ratio of 0.5.
Wind turbine PREPARATION, AND ITS WORK
Blade 6 are initially set, for which the platform 17 is rotated so that the rotor axis coincides with the wind direction. Each blade 6 is in turn in its lowest position, and the brackets 11 to which is mounted an axis 6 adjustable blades, become perpendicular to the surface of the platform 18. The plane of the blade 6 is installed parallel to the platform 17. By including traction motors mounted on the carriage 19, the platform 17 unfolds on the wind flow. The incoming wind flow, acting on the blade 6 and creates a torque of the rotor, while the interaction of gears 2-4, 5-7, 8-9 6 plane unfolding blades at an optimal angle to the wind flow. The blade 6, which has appeared in the upper position during obeganiya 1 around the central axis becomes perpendicular to the wind flow and, thus, the maximum torque of the rotor will receive at the greatest distance from the ground, where the wind speed is greater than at the surface. Depending on the speed of wind flow turns required amount of energy converters and selects a desired angle between the rotor axis and the wind flow. When Burevoi wind speeds when the need for prevention or repair, the platform 17 is rotated so that the rotor axis coincides with the direction of wind flow, with the blades 6 are parallel to the plane of the wind flow. In this case, no rotor torque and the rotor stops.
In the design and operation of wind turbines of this type are of great importance is the fact that the efficiency and effectiveness of the proposed wind turbines does not depend on the change of the wind direction is reversed, that is an original feature of their symmetry. Industrial application of the invention will allow to solve many problems of energy supply without pollution.
