Abstract

FIELD: wind power.

SUBSTANCE: invention relates to wind power. The rotary wind turbine contains a base, traverses, wind receivers and a central rack. The inner surface of the wind receivers is equipped with rectangular flexible planes, made with the possibility of opening up to pressing them against the inner edges of the wind receivers when the wind flow runs in and closing when the wind receiver moves against the flow.

EFFECT: providing the possibility, on the one hand, of laminating the wind flow at the wind receiver moving against the flow, and on the other hand, increasing the effective cross-section of the wind receiver moving along the flow.

Description

The invention relates to the field of wind energy, in particular to wind turbines of segment and arc type, mainly with a vertical axis.

Known wind turbine rotor [US Pat. RF No. 2290534, publ. December 27, 2006, bul. No. 366, s-ka 2005116803/06, 06/01/2005]. In this technical solution, a technical result has been achieved, which consists in reducing the mass and dimensions of the rotor of a wind power generator while minimizing its cost by simplifying the manufacturing technology and ensured due to the fact that in the rotor of a wind power generator containing a hub, blades, arcuate elements and magnetic circuits, according to the invention, the rotor magnetic circuit made in the form of ferromagnetic parallelepipeds, alternating with non-magnetic prisms, the bases of which are made in the form of isosceles trapezoids, and the side faces are provided with holes for placing fastening elements. The disadvantage of this rotary wind turbine is the possibility of its destruction under the action of centrifugal forces.

Of all known analogues, the closest to the claimed set of essential features is a rotary wind turbine segment wind generator [US Pat. RF No. 2275530, publ. 04/27/2006, bul. No. 366, s-ka 2004128674/06, 09/27/2004]. SUBSTANCE: rotor of a segmented wind power generator contains a hub, blades, arched elements, magnetic circuits, wind collectors, traverses and a column. At the same time, the magnetic circuits of the rotor of the segmental wind power generator are made in the form of coils of ferromagnetic wire, which are mounted on arcuate elements. Thus, a rotary wind turbine contains a base, traverses, wind collectors and a central rack.

The disadvantage of this rotary wind turbine is the reduced efficiency associated with a low degree of flow laminarization.

The invention is aimed at providing the possibility of increasing laminarization.

The achievement of the technical result is achieved by the fact that the rotary wind turbine containing the base, traverses, wind turbines and the central rack, according to the invention, the inner surface of the wind turbines is provided with rectangular flexible planes.

The essence of the invention is illustrated in the drawings, where in Fig. 1 shows a top view of a rotary wind turbine, FIG. 2 is a front view, FIG. 3 shows a view of the wind turbine downstream, FIG. 4 shows a wind turbine upstream, FIG. 5 shows a development of a flexible plane.

Rotary wind turbine contains base 1; traverses 2; wind collectors, convex-concave shape 3; central post 4. The inner surface of the wind turbines is equipped with rectangular flexible planes 5. The planes are fastened with fasteners 6. Each plane contains a strip 7 intended for fastening.

Device operation. In the absence of a wind flow, the flexible planes assume the position shown in Fig. 1, that is, the average position relative to the axis of symmetry of the wind turbine. When the wind flow runs, the planes open until they are pressed against the inner edges of the wind collectors - see Fig. 3. In a wind turbine moving against the flow, the closure of the planes occurs in the opposite direction, that is, in the direction of the axis of symmetry of the wind collector. In this case, the general configuration of the wind turbine moving against the flow approaches a drop-shaped one, which contributes to the laminarization of the flow.

Technique-economic advantage is, on the one hand, the possibility of laminarization of the wind flow at the wind inlet moving against the flow, and on the other hand, an increase in the effective cross section of the wind inlet moving downstream.
