Definitions
- the invention relates to wind energy and may find application for autonomous power supply of facilities and the generation of electricity in a power system.
- the technical result is an increase in the utilization of wind energy over time, regardless of its direction and speed, simplifying the design and improving operational characteristics, reducing manufacturing costs and operating costs, increasing reliability while increasing the unit power of the wind farm.
- This is achieved by the fact that the power plant has brackets, a bearing assembly with a housing, drive and driven gears, rods, arms with a stand, an L-shaped lever with a load, blades that are made in the form of two or more segments of the outer part of the hollow torus and having an upper and the lower edges, as well as the inner and outer ends.
- the outer part of the hollow torus segment is an outer semicircle in cross section, which allows it to be presented in cross section as part of a car tire of a simpler shape (in the form of a semicircle).
- Brackets are rigidly fixed to the bearing housing. Bearings are mounted on a fixed axis. Each blade between the inner and outer ends from the upper and lower edges is pivotally attached to the brackets. The rods are pivotally attached to the blades between the center and the outer end at the upper and lower edges. At the other end, the rods are pivotally attached to the adjacent blade from the outside by means of levers with a rack. Racks are rigidly attached to the blades. One blade is pivotally connected to an L-shaped arm-bracket, on the opposite end of which a load is attached. The lever bracket with the load is pivotally attached to the drive gear housing. The pinion gear is engaged with a pinion gear of a smaller diameter, which is rigidly attached to the driveshaft or to the ball shaft. The fixed axis is inside the pinion gear. Cardan shaft (or shaft with ball mount) is connected from below to an electromechanical installation. The fixed axis is rigidly attached to the support.
- Brackets are rigidly fixed to the bearing housing. Bearings are mounted on a fixed axis. Each blade between the external and internal ends is hinged from the outside with an arm by means of leverage arms with uprights. Racks are rigidly attached to the blades.
- the bracket is pivotally connected to the L-shaped lever with racks in the center. The ends of the leverage arms with uprights are pivotally connected to the rods.
- One of the blades is pivotally connected to the L-shaped lever-bracket, on the opposite end of which a load is attached.

- This wind rotor power plant has a number of disadvantages, such as high metal consumption, the need for high manufacturing class for its operation at high wind speeds, which leads to a significant increase in cost, inoperability at low wind speeds.
- PK JYs3230 patent a Savonius wind turbine containing two semi-cylindrical blades located between the boards and having external and internal edges that are kinematically connected rigidly to the shaft and articulated with the blades provided with weights at their external edges.
- This wind turbine has a significant drawback, consisting in the fact that the diameter increase required to increase power is more than 0.5 m and the edges of the blades turn to the wind, an uncontrolled shift of the half cylinders under the pressure of the wind occurs and the brackets strike, which requires complexity of the design and reduces the reliability of the device.
- a decrease in the diameter of the half-cylinders leads to a decrease in power and a reduction in the range of operating wind speeds.
- the objective of the present invention is the development of a wind power plant (WPP), which allows to increase the utilization rate in time (to expand the range of operating wind speeds), to provide a constant power of the power plant regardless of wind speed and direction, to simplify the design and improve reliability, with a significant increase in power, which leads to to reduce the cost and operating costs.
