The present invention relates to rotary power uses the kinetic energy of the flow of wind or water to convert it into mechanical energy of rotation.

Known similar device on the author's certificate of the USSR No. 1650948, the rotor of a wind turbine "Dolphin Tail"containing a flexible plate-blade, fixed front edges on the fixed axes associated with rims (disks), which with the help of the spokes are connected with a vertical shaft installation [1].

The disadvantage of this device is very small resource, since the plate-blades rigidly attached to its movable axes and are rejected from the stream only due to its flexibility, which have finite limits on the number of bends in both directions: inward and outward of the rotor. In this device for one revolution of each rotor plate blade is deflected twice. In addition, for different power energy flows would need to find and replace the plate - blades of varying degrees of elasticity.

It is also known device "Rotor "Dolphin Tail"" a utility model patent of the Russian Federation No. 34653 containing between rims disks movable blades placed on the sleeves of their axes and spring-loaded by springs with opposite twist [2]. The blades in this device have the capability of disturbances is taken inward and outward at the corners, determined by the elasticity of the twisted coil springs. The resource of this rotor more, however, is also limited and is determined by the reliability of a large number of balanced springs and other associated nodes.

Because over time, the spring parameters change, you have to adjust the degree of elasticity (stiffness) by curl to one side or the other of springs for installation in equilibrium initial state of the blades in the absence of flow, representing the shape of a polyhedron.

As the prototype is set to "Tetragidroksistil" on the patent for utility model RF # 55884 containing a shaft connected with the rim disks, between which on their axes set the blade with the levers along the plane of the blades and connected through flexible rod, swivel bearings, springs and tensioners with one of the rims-ROM drive [3].

In this device the springs are reduced in two times, and instead of a complicated adjustment of the springs on the twisting applied more simple spring tension. Simplified the installation process of the rotor in the initial state of the polyhedron in the absence of flow through the use of flexible rods, slewing bearings and tensioners.

However, this device is not reliable due to the presence of constantly running springs in tension, par the meters which change over time and require adjustments, or replacement of springs in connection with their failure.

In addition, when changing the parameters of the springs during operation of the device also changes the angles (angles of attack) of the blades relative to the flow, and, accordingly, decreases the stability and efficiency of the installation.

Technical advantages of the claimed subject matter are as follows.

To solve the problem of increasing the reliability and efficiency of the device in a turbine with a shaft connected to disks that have established on their axes blades, equipped with arm connected with one of the disks by means of flexible rods, slewing bearings and tensioners, advanced disk with holes, flexible rod passed through a swivel bearing holes down the tensioners are made in the form of goods attached to the ends of the flexible rods and between the cargo and the surface of the disk placed on the flexible rods added spring in compression and sliding sleeve.

In addition, the spring compression, the cargo and the sleeve sliding on the ends of the flexible rods are placed in the tubes attached to one ends to the disk, and the other ends of the pipes set screws for fixing the initial position of the goods and, accordingly, the initial angle of attack for weak energy flows.

Distinctive features is that instead of elastic springs stretching is their applied loads, having a constant weight, so the weight force, which loads act on the levers of the blades remains constant in nominal specified range of flow velocities that provides a uniform stable rotation of the rotor and does not require additional adjustments. The extension of the nominal specified range of operating speeds is provided, if necessary, an additional spring in compression, the force of elasticity which is added to the force of the weight when increasing the flow rate above par, and in case of emergency (burevoy) flows is full spring compression, the blades are in the feathered position, which prevents the installation from damage.

The hallmark is that loads, springs and sliding the sleeve over the end of the flexible rods are placed in the tubes attached to one ends to the disk, and on the other ends of the pipes installed adjustment screws to set the initial angle of attack of the blades for the weak flow with low velocities.

In the search for sources of patent and scientific and technical information, the totality of the characteristics of the proposed device was not found, therefore the present invention meets the criterion of "new".

On the basis of comparative analysis of alternatives the proposed solutions with known, Ural branch of the it equipment sources of patent and scientific and technical information, it can be argued, between the set of features, including distinctive, their functions and achievable purpose, the proposed solution is not clear from the prior art and, therefore, meets the eligibility criterion of "inventive step".

We offer rotary tetragidroksistil shown on the drawings:

figure 1 - view of the device from above taken from the top disc 2 - side view on the design of one of the tensioners for each blade of the device.

The blade 1...9 (for the given design nine pieces) posted on its axis 10 between the disks 11 (the upper disk is removed) with the possibility of rotation of the blades inward and outward of the rotor (figure 1). Each blade has a lever 12, which are connected through a flexible rod 13 through the rotary support 14 and openings 15 in the disk with loads 16 (figure 2).

Between the cargo and the surface of the disk on the flexible rods are placed in the tubes 17 of the sleeve 18 slides and springs 19. At the end of a pipe set screws 20. To the Central axis 21 are attached to the upper and lower disks of the rotor, and through mechanical drive axle is connected with an actuating mechanism, such as an electric generator (not shown).

Wind turbine rotor operates as follows.

In the absence of flow V wind or water loads 16 under the action of its gravity pull through the flexible thee and 13, missed in the holes 15 of the disk, and the rotary support 14, the levers 12 of the blades 1...9, with the blades take the shape of a closed deletepolicy and the loads 16 are located in the extreme lower positions. The location of the blades at this point, figure 1 shows in phantom lines.

In order to improve the initial moving of vetrogidroenergetica with low thread screws 20 rigged to lift their cargo 16, with rod 13 to reduce the transmission of forces from the cargo on the levers 12 of the blades and the latter have the possibility of low turn on their axes 10 and to create a certain initial angle of attack to the flow. This position of the blades shown in figure 1 by dashed lines.

With increasing flow velocity V in the range up to the rated value is the deviation of the blades at high angles of attack, and the rotor rotates clockwise.

For one revolution of the rotor, each blade is deflected from the initial state twice: inward and outward of the rotor and, accordingly, the cargo of the blades twice up and down to its original lower position.

The weight of the cargo is selected as the optimal angle of attack (angle) of the blades at a nominal flow rate, for example for wind speed, specific GOST, from 8...10 m/s

Power weight unchanged and therefore, when an abrupt is Ananiah flow velocity of the blade disclosed in greater angle, passing through the rotor part of the flow, while the rotor speed is not changed.

The position in space of the blades of the device are presented in figure 1 at a certain point in time. From the effects of flow V of the blades 1 and 2 are deflected inward of the rotor blades 6 and 7 are deviated outward from part of the flow V1passing through the rotor and the blades 3, 4, 5 receive their energy from the outer part of the flow V2where V=V1+V2. Thus, a large portion of the blades of the rotor are involved in taking kinetic energy from the stream.

After reaching the maximum value of the range nominal flow rate and further increase the levers of the blades 12 continue to pull rod 13 until the contact plugs 18 slide with the plane of the disc 11.

With further increase of the flow rate begins to compress the spring 19, thus reducing the impact kinetic energy of the flow on the blade, since the force of the springs is summed with the force of weight. Selecting specific parameters of the springs, the opportunity to adjust the speed of the rotor in an extended range of flow rates.

When the flow velocity reaches the emergency (burevoy) velocity of the blade 1...9 take a directional position along the stream. Figure 1 their position shown double-dashed line, while the spring 19 (figure 2) are in the atom state.

After passing emergency flows under the action of springs the blade back into working condition, adjustable force of the weight of the cargo.

Thus, in the proposed device with increased reliability and efficiency is achieved by using a more simple nodes and links between them.

Use freely pulling loads when opening the blades eliminates continuously operating during rotation of the rotor unreliable spring torsion or tension, and to exclude initial adjustment of the device, because in the absence of flow, the blades under the action of not changing weight loads are always installed in the original polyhedron. Applied in this device, the spring compression is used in short periods or exceeding the flow rate from nominal to extend the range of use of a wind turbine, or as emergency protection.

This design allows maximum use of the kinetic energy of the flow in a wide range of speeds, and to provide effective weaning energy from the flow of rapidly changing parameters.

Laboratory tests of the layout of the proposed wind turbine confirmed the claimed characteristics.
