DESCRIPTION OF THE INVENTION

The invention relates to wind energy, namely wind turbines used for autonomous power supply.

Known wind turbines with a rotation axis perpendicular to the wind direction, having mounted on a vertical shaft swings, frame or stem, provided with stops moving, and bearing on them hinged blades cyclically interacting with stops (1, 2). For wind energy conversion vertical support shaft is kinematically connected with the generator shaft, the kinematic connection formed as a cylindrical gear pairs with a specific gear ratio.

Known wind turbines convert wind energy to the blades depending on the positions in relation to the wind direction, i.e. provide a pulsating nature of the withdrawn capacity, which reduces their efficiency at high material consumption and design complexity.

Known wind turbine (3) closest to the proposed, passed as a prototype containing a support, two pairs of rotary blades at a constant working area, interacting with stops and installed on mahah mounted on a vertical support shaft and a horizontal platform, coupled with moves. The support of such a wind turbine installed under the horizontal platform and is equipped located in the upper part of the closed circular track, mahi - in contact with her frames and blades - spring-loaded shock absorbers, reflectors associated with moves. The blades are pivotally mounted on the longitudinal end mahah and rotated at an angle to Mahama and abutments are in the form of cables connected to the shaft ends and strides.

Wind turbine with a relatively simple design provides a slight increase in efficiency, however malomoschen and does not allow for adjustment of the conversion of received energy, just reliable, especially in rain and sleet.

The object of the present invention is to provide a simple-technology wind turbine, which provides high efficiency and increased capacity of the regulatory structure, with sufficient reliability.

This object is achieved by a wind turbine comprising a support swivel reflector blades interacting with stops in the form of cables and hinged longitudinally mahah mounted on a vertical shaft, kinematically connected to the generator shaft, a horizontal platform and placed a ring rail in the upper part of the support, contacting blades via reflectors according to the invention in which the guide is made integral and one of its parts - the lifting-Surge, and each blade is installed with its symmetry axis offset relative to the longitudinal axis of swing by an amount selected from the ratio 1/5 - 1/4 of the blade width . Each blade may be provided with a variable area, which is provided with at least native additional blade placed on the additional Mahe analogously main blade and connected thereto through mounted mahah vertical rigid tie with the shaft and hinged three-link boom mechanism of the working end blades. This wind turbine reflectors placed on the main blades at the periphery by a vertical shaft, and stops in the form of cables - at the top of additional mahah. In this wind turbine support is placed on a horizontal platform mounted above the battery, which is equipped with a wind turbine, cinematically connected to a generator.

Comparative analysis of the prototype shows that the proposed wind turbine differs from the prototype design performance of the guide and the predetermined offset blades that provides guaranteed cyclic installing blades vertically and / or at the desired angle to the wind load, which allows to create the maximum effective working blade area, but also eliminate the sticking wet snow on them, which prevents breakage and bending of the blades and swings, and generally improving the reliability and capacity of the structure.

The proposed value of the symmetry axis of the displacement of the blade from the maha-axis determined experimentally and is optimal, because It provides additional torque blade about the axis (the rotation due to the suspension knuckle mahe) reflector at the termination of the contact with the guide ring. Implementation of the axis of the blade axis offset by maha on which it is suspended by an amount less than the proposed, by reducing the unbalanced weight loads on the hinge suspension blades, does not guarantee the required its installation, and the choice of said bias offer to be inappropriate, because wherein the wind turbine will have a low conversion efficiency of wind power.

Performing the blade area by a variable number of additional supply it in a certain way connected to the main blades, at least one, to create a wind turbine with a given power, high efficiency due to the required performance of the blades with an effective area of ​​wind resistance.

Thus, the claimed technical solution meets the criteria of a wind turbine, "novelty" and "inventive step".

The proposed wind turbine is illustrated by drawings, where:

Wind turbine

FIG. 1 shows schematically a wind turbine, a general view; FIG. 2 - team blade and a battery (Figure 1.); FIG. 3 shows a view II (FIG. 2), the suspension load battery assembly.

Wind turbine 1 comprises a support, rotating the blade 2, which interact with stops in the form of cables 3 and is pivotally mounted on longitudinally mahah and 4 mounted on a vertical shaft 5 which is kinematically connected through, for example, the gear 6 to the shaft 7 of the generator (not shown). The support 1 is placed on a horizontal bearing area 8, and in its upper part an annular guide 9 that contacts with the reflector 2 via the blades 10, made of, for example, a spring or hydraulic damper. The guide 9 is designed as a composite, for example, of two equal parts - the half-rings, one of which 11 is made stationary, and the other - 12 - lifting-Surge, by a known actuator, such as mechanical, hydraulic, etc. (Not shown). Each blade 2 is mounted on four Mach offset its axis of symmetry relative to the longitudinal axis of swing by an amount "h", of certain selected empirically ratio 1/5 - 1/4 of the width of the "H" blade 2. In order to increase the effective area of ​​the blades 2 providing improving efficiency of a wind turbine and, accordingly, the required power, each blade 2 is formed with a variable area by a rigid installation above the at least one additional blade 2 (Fig. 2) arranged on the additional Mahe analogously main blade and connected thereto through mounted mahah vertical ties 13 rigid with the shaft 5 and a three-link articulated boom mechanism 14 mounted at the working end of the blade 15 2. depending on the requirements of the wind turbine may have one, two, three, etc. number of vertically mounted blades, connected by a single rigid spaceframe wing rotatable around the shaft 5, and the reflectors 10 are mounted on the lower main blades 2 at the periphery with the shaft 5 and the stoppers 3, made in the form of cables, connect the ends of the shaft 5 with the upper additional 4. strides to ensure an autonomous supply of electricity wind turbine facility may be provided with a battery 16 cinematically connected by, for example, a gear 17 to a generator (not shown) and mounted under the horizontal platform 8, made a mounting platform. Battery 16 can be, for example, a certain predetermined amount of cargo weight suspended on a rotary drum 18 mines.

Wind turbine works as follows

In the absence of wind vanes 2 by gravity installed in the vertical position and the guide portion 12 is lowered to the horizontal surface 8. When the wind appears under the force of the wind flow blade 2 in contact with the guide 10, reflectors 9 and its stationary part 11, and take a horizontal position . The guide portion 11 retains the blade in a horizontal position during rotation through 180 o. Reaching the end of this part, the blade 2 through an axis offset from the swing axis 4 by a predetermined amount by gravity takes the inclined position, and then - the vertical. If a strong wind flow (at high speed) significant deposits in order to avoid breakage of the blades if necessary operation of a wind turbine, mounted guide portion 12, providing additional support to the blades 2. To exclude the operation of a wind turbine, increasing the reliability and durability of the structure, if necessary, the reflector 10 is output from the contact zone blade 2 with the guide 9 due to its spring-shock-absorbing properties.

wind turbine model has been manufactured and tested in the laboratory. Tests at 3, 8, 13 m / s wind flow (up to 20 m / s) showed that the wind turbine provides the expected results, namely a small consumption of materials, manufacturability, reliability of the design, wind energy conversion efficiency. By calculation, as an example of execution, it is established that one blade at a value of the movement area to about 40 m capable to develop electricity to about 100 kw, with the blade-wing can be entered with three rows of vertically mounted blades, and to provide stored energy to 0.5 months of the total value of the battery load can be up to 10 tons.

Thus, the proposed wind turbine meets the criterion of "industrial applicability".
