The invention relates to wind power and for wind turbines.Known wind mouth who has the necessary reliability.Closest to the technical essence and the achieved result is a wind power installation, comprising suspended on the lifting device getrowsperpage working body and associated with flexible shaft generator installed on ground-based, in which the working body in the form of elastic mesh panels, curved spiral surface, and the ropes attached to the corners of his cell, and the flexible shaft is designed as two cables, connected among themselves by means of evenly spaced transverse rods, the lower of which is connected to the generator, and the upper lifting sling (see and.with. USSR N 1302011, 1987).The disadvantages described above technical solutions are low efficiency, high cost due to the need of the use of lifting devices.The aim of the invention is to increase the efficiency and reliability of the plant.The objective is achieved by the fact that wind energy facility containing pivotally mounted in the housing of the working body with two shoulders lever associated transmission including a main shaft and ratchet, with generator, two shoulders lever is equipped with dome installed in we believe larger than the diameter of the disks, transmission provided with guides, a spring-loaded counterweight located in the past with the ability to move, two drums, one of which is connected with the lever, and the other with a counterweight, additional ratchet and three horizontal shafts, the last and main installed in pairs and connected by means of gears, each pair of shafts mounted parallel to each other, the shafts of each pair of coaxial, drums and ratchet mechanisms are placed at the ends of the respective shafts of each pair, and the free end of one of the shafts associated with the generator. In addition, wind power installation is provided with an additional generator associated with the free end of one of the horizontal shafts.In Fig. 1 shows a wind power installation, General view; Fig. 2 - the same, top view; Fig. 3 - two coaxially of the shaft, interconnected by means of a small lever and ratchet wheel with the dog, and the generator, i.e. the transfer from the working body to the generator.Wind power plant consists of a body 1 on which the hinge has a working body consisting of two shoulders of the lever 2 and the dome recruited from metal disks 3, nab is left from separate sections to achieve the required height of the working body, and for ease of installation. The working body by means of a rope 5 through the power rollers 6 is connected with the drum 7, sitting on the shaft 8, which is fixed to the gear 9 and the small lever 10 with the ratchet pawl 11. With the shaft 8 coaxially connected to the shaft 12 with the ratchet wheel 13 and the gear 14, the end of which is connected to the engine 15. The gear 9 is connected with the gear 16, which sits on the shaft 17 and is connected with the gear 18, sitting on the shaft 19 with the drum 20 at one end, the rope 21 which is connected with a spring-loaded counterweight 22, and a small lever 23 from the ratchet by the pawl 24. With the shaft 19 coaxially connected to the shaft 25, on which sits a ratchet wheel 26 and gear 27 connected with the gear 14.For turning the working body are rotatable frame 28 and are inside of the axle 29 of the working body. The lower end of the short arm two shoulders of the lever has a rubber ring 30 to absorb the shocks of the working body of the case.Under the wind pressure dome (performing the function of a sail) turns long shoulder 2 two shoulders of the lever of the working body, for example, from left to right. Because the axis 29 is rotatable frame 28, short one shoulder two shoulders of the lever rotates from right to left.The rope 5 working body, one koneti 6. The second end of the rope 5, which is wound on the drum 7, turn it from right to left. As the drum 7 and the small gear 9 sit on a common shaft 8 and gear 9 rotates from right to left. In this same direction will rotate the gear 18 connected with the gear 9 through the driven gear 16
At the same time on the drum 20 begins to nakativaetsa rope 21, the counterweight 22, attached to the other end of the rope 21, ascends along the guide.By the end of the stroke of the rubber ring 30 smartserve kick. The counterweight 22 located in the upper position under the action of its gravity, will fall down, unwinding the rope 21 of the drum 20. At this time, the rope 5 will gather around the drum 7. This ratcheting pawl 24 will make working stroke by turning the ratchet wheel 26 from left to right, and ratcheting pawl 11 will be idle to jump on the teeth of the ratchet wheel 13, making the second stroke.If one rope drum is unwound, the stroke is made from the gravity of the counterweight and the other drum at this time wrapped the rope, and so is repeated until there is a fluctuation of air in either direction.Long shoulder, two shoulders of the lever may be more short shoulder 10-15 times. VA is Yu existing will receive power almost constantly, because the installation reacts to small oscillations of the air. The device may be assembled in a few minutes and work in any area, even with low winds. 1.

SUBSTANCE: invention relates to on-coming energy converters used in wind-power engineering, hydraulic power engineering and instruments. In proposed method two physical are used simultaneously, namely, self-excited oscillations and electromagnetic induction. Conversion of energy of on coming flow is provided due to electromagnetic induction appearing at self-excited oscillations in metal strings (flexible conductors) arranged in on-coming flow and placed in magnetic field. According to law of electromagnetic induction, metal string executing oscillatory movements in magnetic field becomes electric energy (current) generator.
EFFECT: increased power output of converter by increasing number of strings to required value.
