DESCRIPTION OF THE INVENTION

The invention relates to wind power generation, in particular to wind power plant designs, and can be used to generate electricity in a remote location from electric networks or as a drive to various mechanical devices, incl. To water pumps for lifting water from wells or for recharging a battery pack.

Known is a wind turbine comprising a impeller with a vertical axis of rotation on which pivots are mounted rotatable about vertical axes having an individual pivot mechanism made in the form of a weather vane kinematically connected to the blade rotation axis (see RF Patent No. 2119094, F 03 D 7 / 06 of 20.09.98). However, this design is quite complex, and the relationship between the weather vane and the blade rotation mechanism is constantly loaded, which can be attributed to the drawbacks of the known design.

A wind turbine is known, comprising an impeller mounted on a vertical shaft with upper and lower spokes, between which at their ends are located rotary balancing blades, whose shafts through couplings are connected by a chain transmission with a common wind vane (see AS 1483081 dated May 30, M. Cl. F 03 D 3/02). The performance of rotary blades makes it possible to orient them optimally in the course of work, which ensures optimal aerodynamics of the blades when moving along and against the wind.

However, the general mechanism of rotation of the blades, which is a chain link connecting the weather vane with each blade, is complicated, which reduces the reliability of the device. In addition, the chain transmission can not be sufficiently rigid, which causes an increased level of self-oscillations, which in turn is the cause of unexpected failures in the operation of the wind turbine and low efficiency of self-protection of the windmill from strong winds. All this is the fault of the well-known wind turbine.

A more advanced wind turbine is known, a prototype comprising a impeller with a vertical axis of rotation on which pivots are mounted rotatable about vertical axes having an individual pivoting mechanism made in the form of a weather vane kinematically connected to the blade rotation axis, the upper end of each blade being formed with The possibility of deflection in the plane of the blade symmetrically with respect to the vertical axis by a distance not exceeding B / 5.27, where B is the maximum value of the blade width. Each weather vane is kinematically connected to the pivot rotation axis by means of an unloading mechanism, which is made as a safety clutch (see patent of the Russian Federation No. 2193688, M. Class F 03 D 7/06).

The known design of the wind turbine - the prototype is quite complex and does not prevent undesirable and uncontrolled vibrations of the blades during the operation of the plant, which reduces the reliability of the plant, can lead to its destruction and which expends additional energy, which can be attributed to the shortcomings of the known device.

The object of the present invention is to eliminate the disadvantages of the prototype, in particular, to increase the reliability, efficiency and simplification of the design of the wind farm.

The task set by the invention is achieved by the fact that the means receiving the wind flow is made in the form of two blades rigidly connected to each other and mounted on one horizontally located rotary axis on opposite sides of the vertical support of the wind farm, the blades of one means being mounted in relation to each other To a friend at an angle of 85-95 degrees, and each subsequent means is mounted on a vertical support at an angle of 90 degrees with respect to the other, each means being provided with a rotation limiter.

The stopper of the means that receive the wind flow is rigidly mounted on the horizontal axis of rotation of each means and is connected to the vertical support of the wind farm.

The stopper is made in the form of an elastic lever.

The signs that the means receiving the wind flow are made in the form of two blades rigidly connected to each other and mounted on one horizontally located rotary axis on opposite sides of the vertical support of the wind turbine, the blades of one means being mounted with respect to each other at an angle of 85-95 degrees, and each subsequent means is mounted on a vertical support at an angle of 90 degrees with respect to the other, each means being provided with a rotation limiter, which are significant, unobvious, unexpected, necessary and sufficient to achieve the objective of the invention. Thus, the implementation of blades that perceive the flow of wind at different angles - one with an advance of 85-95 degrees relative to the other of each means that perceives the wind flow, allows alternately and completely to perceive the flow of wind by one blade of the means, and the other blade, The other side of the rotating support of the wind farm, its plane is located along the wind flow, without exerting any resistance. The arrangement of one means in relation to the other at an angle of 90 degrees on the rotatable support allows to ensure the uniformity of rotation of the support of the wind farm and to make maximum use of the efforts of the wind flow.

The absence of vortex parts uncertainly and unforeseenly fluctuating when perceiving the wind flow ensures the reliability and durability of its operation.

The presence of a stopper of the means that perceives the wind flow rigidly connected with the horizontal axis of rotation of each means and which is connected to the vertical support of the wind farm allows one to accurately establish one blade surface of the means perceiving the head of the wind flow in the frontal plane and the other in the horizontal plane and thereby achieve The maximum possible effort of turning the vertical axis of the wind farm at a given head of wind.

The execution of the rotation limiter in the form of an elastic lever allows smoothly without knocking as the blade rotation angle is increased, to establish the blade surface of the receiving wind flow in the frontal plane.

WINDOWS

1 schematically represents the proposed wind turbine at the time when the wind flow is perceived by the blades on the left side.

FIG. 2 shows the position of the blades of the wind receiving means.

The wind turbine consists of a rotatable support 1 held in the upright position by several lateral ties 2 and a base 3. On the height of the support 1, at least one row of means 2 and 4 of the means 6 receiving the wind flow is mounted, The means 6, which receives the wind flow in relation to the blade 5, is mounted at an angle of 85-95 degrees. The stop 7 is rigidly connected to the rotating horizontal axis 8 of each pair of blades 4, 5 of each wind receiving means 6 and is connected to the outer surface of the rotating support 1. At the bottom of the turntable 1, a drive 9 with a drive disk 10 with a gear 11 and a generator 12. In the center of the support bearing 13 of the rotatable support 1, a shaft 14 is connected, which is connected by means of a flange 15 to the support 1. A link 16 is secured to the shaft 14 to remove mechanical forces and transmit them to various devices, for example a water pump 17. At the top of the rotating support 1 Wind installations on the bearing 18 is mounted the crosspiece 19. The ties 2 hold the rotary support 1 in an upright position.

THE OFFERED WINDOW WORKS AS FOLLOWS:

In the initial position, in the absence of wind, the blades of each wind receiving means 6 with paired blades 4, 5 with respect to the vertical support 1 are at an angle of 45 degrees.

With the head of the wind and its impact on the surface of the blades of the flow receiving means 6, each of the blades 4, 5 tends to deflect under the wind pressure in the direction of the wind flow. In this case, one, for example, the left, the blade 4, turning relative to the horizontal axis 8, perceives the flow of wind with the increase in the surface of the perception of the flow, and the right blade 5 during the same time is set in a horizontal position and does not resist wind Support 1 of the wind farm. With the steady flow of wind on the blade of the flow receiving means, each time the left blade 4 is installed in the frontal plane and maximally perceives the wind flow, and the right blade 4 is deflected back and set in the horizontal plane. The wind pressure, acting on the left side of the blades 4 of the wind turbine, begins to rotate it relative to the vertical axis of rotation. As soon as the right blade 5 is positioned opposite to the vertical axis of the support, its plane from the horizontal position as it rotates successively passes with respect to the rotating support 1 of the wind turbine first at an angle of 45 degrees and then, gradually turning, passes to the left side of the wind farm and begins to perceive the flow with Increase in the surface of the perception of the wind flow, and the plane 4, which was on the left side of the support 1, and gradually as the vertical support 1 of the wind farm rotates, turns to the other side of the support 1 and goes horizontal to the horizontal plane with minimal resistance to rotation of the support and wind flow.

Thus, the head of the wind flow constantly acts on the left side of the wind farm and rotates it. The rotation of the wind turbine, if viewed from above, is clockwise regardless of the direction of the wind. Transmitted to the generator 12 via the drive disk 10 and the reduction gear 11, the rotation of the wind turbine support 1 provides power generation and allows the mechanical energy to be removed from the rotating link 16 of the drive, for example to the pump 17 of the spider 19 mounted on the bearing 18 of the support 1, to allow free rotation of the support 1.

The current model of the proposed wind power installation was made by the authors and experimental tests were carried out. A wind turbine with a surface area on one side of the support 1, receiving a wind current of 6 m 2 and a wind speed of 7 m / s successfully through the reducer operated an automobile generator and generated electrical energy of about 200 W / h, which was sufficient for the operation of a television, one lamp Lighting capacity of 40 watts and recharging of batteries.

When connecting the swivel arm 16 through a system of levers with a pump, the wind turbine provided the transfer of water from one container to another with a capacity of about 200 liters per hour. We believe that the connection of the wind farm to the well pump will ensure at least the same capacity when pumping water.

Currently, the windmill of the proposed construction with a working surface is located at the stage of manufacturing, on the one hand it perceives a 10 m 2 wind flow that will be installed in the mountain Altai on the farm pasture to generate electricity for lighting, radio operation and water heating for livestock.

We believe that the proposed wind turbine will be widely used in farms, fruit and vegetable growing societies, in irrigating forest plantations and nurseries, and can be used to create water reservoirs for irrigating forest belts and extinguishing fires, at anchorages of shepherds, for forecasters, foresters , In hunting farms, etc., especially in places where there is no electricity.

The wind turbine is simple in design and reliable in operation.
