Wind wheel with blade elbow bend

A wind wheel comprising:

• a main shaft, wind plant hub and blades, each blade comprising two parts:
• a short part with axial and sleeve segments connected at an angle and a long wing-shaped part connected to the sleeve segment with an end shaft and by support devices with bearings, wherein the short part is made of steel, and at a distance of 1.5-5 meters or 0.20-1.5 meters from a connection between the short part and the hub, the angle between the axial and sleeve segments forms a 10°-80° elbow bend opposite a direction of rotation of the wind wheel, wherein the sleeve segment of the short part has a cylindrical skeleton and is connected to the wing-shaped part of the blade, wherein a root end of the wing-shaped part is supplied with a hollow steel shaft, wherein said shaft is connected with a skeleton of the wing-shaped part by tensioning bolts, wherein at the end of the sleeve segment close to the elbow bend are installed hydraulic mechanisms connected to the end of said shaft of the wing-shaped part via cams enabling the rotation of the wing-shaped part along an axis, wherein the cylindrical skeleton of the sleeve segment comprises three double support rings and in that said shaft of the wing-shaped part comprises three removable protuberances with bearings, wherein the three removable protuberances with bearings are inserted between the three double support rings and are tensioned to the shaft with bolts.
