Abstract

FIELD: wind energy.

SUBSTANCE: wind power generators with a vertical axis. Rotary vertical wind turbine contains a base, traverses, wind collectors and a central post. The outer and inner surfaces of the wind collectors are provided with flexible triangular-shaped plates, designed to open when the wind flow approaches and close relative to the axis of symmetry of the wind collector when the wind collector moves against the flow. The plates are fastened with fastening elements that simultaneously pass through the outer plates, the surfaces of the wind collectors and the inner plates.

EFFECT: providing the possibility of laminarization of the wind flow at the wind inlet moving against the flow and increasing the effective cross section of the wind inlet moving downstream.

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 vertical wind turbine, containing the base, traverses, wind turbines and the central rack, according to the invention, the outer and inner surfaces of the wind turbines are equipped with flexible triangular plates, and their fastening is carried out using fastening elements, simultaneously passing through the outer plates, wind collector surfaces and inner plates.

The invention is illustrated in the drawing, where figure 1 shows a top view of a rotary vertical wind turbine, figure 2 shows a front view, figure 3 shows a view of the wind turbine downstream, figure 4 shows a wind turbine against the flow, figure 5 shows flexible plate reamer.

Rotary vertical wind turbine contains a base 1; traverses 2; wind collectors, convex-concave shape 3; central rack 4. The inner and outer surface of the wind turbines are equipped with flexible triangular plates 5. The surfaces are fastened with bolts 6. simultaneously passing through the outer plates, the surfaces of the wind collectors and the inner plates. The plates 5 are triangular in shape, but they are also provided with a strip 7 for fastening.

Device operation. In the absence of a wind flow, the flexible plates take the position shown in figure 1, that is, the average position relative to the axis of symmetry of the wind turbine. When the wind flow runs, the plates open. See figure 3. In a wind collector moving against the flow, the closing of the plates 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.

The technical and economic advantage is to provide the possibility, on the one hand, 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.
