The invention relates to a device for converting energy of a fluid medium and can be used in wind turbines.

A device for the energy of the fluid medium containing the wheel with blades mounted to rotate about their axes. Each lobe is divided by the axis into two parts with unequal squares.

However, the known device has tolti, in wind turbines where the wind direction changes.

The known device for the energy of the fluid (2), adopted as a prototype, includes a housing with installed shaft, the blades can be rotated about their axes, each blade is separated by axis into two parts with unequal squares. In addition, the device is provided with levers attached by its ends to the axes of the blades at the root portions thereof, as well as at the ends of the axes of the blades mounted rollers, the device is provided with a vane rigidly associated Cam disk pivotally mounted on the shaft and cooperating with the rollers.

The disadvantage of the prototype is that it contains blades that are located in the same plane, and this leads to the power limit of the device due to the small area that receives the stream of air.

The essence of the invention is illustrated by drawings. In Fig. 1 shows a device for the energy of the fluid medium, a top view, in Fig. 2 shows the device in side view, Fig. 3 shows a device for limiting the movement of the blades of Fig. 4 - depicts a lever to rotate the blades.

The mouth is through it and forming 6 symmetric ends, which are the flat blade 3 mounted to rotate about their axis 4. Inside the guides, hollow posted by shafts connecting the blades in pairs. On equidistant from the case one ends of the guides are devices 5 that restricts the movement of the blades, made in the form of a nozzle with a bearing 6, is provided with two rectangular plates 7 arranged at an angle of 60oto each other by spacers 8.

To the lower outer corners of the plates attached to the ends of the rigid rod 9, the shape of the nozzle and forming a broken circle, the upper part of which is free from springs 10 mounted on the ends of the rod. The apparatus comprises a lever 11 mounted one of its ends on the axes of the blades 3 at the root portions thereof, and the second ends of the levers 12 to rotate the blades are movable along the circle segment of the rod is free from springs 9.

The blades 3 are separated by the axes in two parts with unequal areas, and is made of lightimage material and secured to the rails by means of springs, while the aspect ratio of the blades is 3:1, unequal square blades are in the ratio 1:2, and the lower part of the blade is located above the axis. what tion areas and is made of lightimage material. They are mounted on the bearing by means of springs located along the guides. Under the action of intense air flow blades take the form of sails. As soon as they go out of scope intense air movement, they rotate about its own axis and take the form of a wing. Thus, on the carrier at the same time there are two blades, one of them in the form of sails, and the other in the form of a wing.

Under the influence of air blades drive lever, which in turn regulate the movement of the blades, preventing their rotation around the axis.

The proposed design of the device prevents blades from breaking, significantly improves performance by increasing power. The device works even at very low flow of air. In addition, it is cheaper than previously known and does not require special maintenance.
