The invention is in the wind energy area, in particular, to the use of wind for generation of energy using horizontal axial-flow turbines. Technical result of the invention is increase of wind energy use coefficient due to special structure of the wind wheel, and reduction of material consumption and weight of the wind turbine. This is achieved through the use of a blade in a form of an ice-hockey stick in the new rotor construction in order to use the free wind flow effectively, and blades consist of two parts: short root and long alary parts. The short root part is made of high-grade steel and consists of axial and hose parts. The short part of the blade is at 1.5-4.5 m (Wind wheel, variant 1) and 20-25 cm (Wind wheel, variant 2) from the engine head, it has a bend of 30-45 0 towards the primary fastening axle. The elbow is reversed, against the blade rotation. The axial part is fastened to the engine head. Long alary part of the blade is connected to the hose part of the short root section. In order to prevent wreckage on the blade bend in case of strong wind pressure, boards of connection of axial and hose part of the short root part are reinforced by additional steel thickening. Axial and hose parts of the short knee section are tightened by ropes in order to reduce the load on the bend. The construction invented applies a principle of a lever with two points (shoulders) of force application on the one side, where the main long part of the blade affects the torsion element through the short knee - the basic shaft with additional force effect, giving an opportunity to use powerful energy generators. |
