The invention relates to electrical engineering and can be used in other fields, for example wind power. The technical result, which consists in increasing the efficiency and lowering the working wind speed zone, is achieved by the fact that the winding portion of the blade of the blade impeller of the wind power device is made with a transverse kink, and the support of the upper and lower part of the blade of the blade impeller of the wind power device is located on the transverse inflection line, And the lower pivoting parts of the blade of the blade impeller can be folded along the line of transverse bend and along the line of transverse bending, and the impeller blades can be extended forward and radially from the axis with a turn to the required angle and folded back and to the axis of rotation.

DESCRIPTION OF THE INVENTION

The invention relates to electrical engineering and can be used in other fields, for example wind power.

The blade impeller of the wind-driven device VEU-8 and VEU-16 [1] is known, adopted for the prototype.

The disadvantage of this blade impeller wind power device is a low efficiency and a high zone of working wind speeds.

The task, to solve which the claimed invention is directed, is to increase the efficiency and achieve a low zone of working wind speeds.

The technical result, which consists in increasing the efficiency and lowering the working wind speed zone, is achieved by the fact that the screw-forming part of the blade of the blade impeller is made with a transverse kink, and the support of the upper and lower helical forming parts of the blade is located on the line of transverse bending, with the upper and lower screw- Parts of the blade of the blade impeller are able to unfold and fold along the line of transverse inflection and along the line of transverse inflection, and the impeller blades of the wind power device are able to move forward and radially from the axis with a turn to the required angle and slide back and to the axis of rotation. In the drawing, an impeller blade of a wind power device is shown, consisting of screw-forming surfaces 1 and 2 with an inflection line 3 and an impeller axis 4 with an impeller blade rotation angle 5. Extended extended position I and a retracted folded position II. The blade impeller of the wind power device operates as follows: with winds in the working speed zone, the extended deployed position I is set, the angle of inclination of the screw-forming surfaces 1 and 2 and the inflection line 3 ensures the highest efficiency by rotating the impeller; With winds in the zone of inoperative speeds, an extended folded position II is set, in which the impeller of the torque does not create and is in a retarded state.
