Description

The invention relates to the field of wind energy and can be used to create new converters of wind energy into electrical energy.

Known wind turbine [Pat. RF №2385147, application No. 2007135964/06, 09.27.2007, publ. 06/10/2009 Bull. No. 16 / Litvinenko A.M.]. The wind turbine comprises a tower, a rotary device, a supporting structure, ducts installed on it, vertical shafts and wind wheels rotating in different directions with blades with a vertical axis of rotation, as well as a tail boom and tail planes, and according to the invention, the ducts are lateral in the form of three sections - a receiving , direct and arched baskets, the last of which is oriented to the blades of a wind wheel, while the peripheral downstream blades of the wind wheel are covered with screens.

The disadvantage of the engine is the presence of additional boxes.

Of all the analogues, the closest to the claimed combination of features is a rotary wind turbine [US Pat. RF №2479748, application number2011110598 / 06, 03/21/2011, publ. 09/27/2012 Bull. No. 11]. The rotary wind turbine contains a rotating base, traverses, columns with energy receivers and a central rack, according to the invention, the energy receivers are made in the form of columns installed between the upper and lower traverses with flexible curtains partially covering them, fixed by one edge along the generatrix of the columns, and the other edge connected by rods with the corresponding edge of the curtains of the opposite column, while the columns are hollow and equipped with windows with jumpers, the windows are located on one side of the columns, id boiling flow. Its disadvantage is the presence of hollow columns, in which, despite the displacement of the curtains, an increase in resistance to the oncoming air flow is observed.

The invention is aimed at simplifying the design, improving reliability.

This is achieved by the fact that in a rotary vertical wind turbine containing rotating bases, traverses, energy receivers, a central rack with a rotary base, according to the invention, each pair of energy receivers is made in the form of intersecting Λ-shaped racks mounted on rotating bases of the lower traverses to the tops of the racks the upper traverse is attached, and vertical posts are installed between the ends of the traverse, and wind receiving surfaces are attached to the last, between which there are tightening springs.

The technical result, which consists in simplifying the design and increasing reliability, consists in the possibility of using passive wind receivers of the sailing type.

The invention is illustrated by drawings, where figure 1 shows a rotary vertical wind turbine, a top view, figure 2 shows an isometric image of one blade.

The wind turbine contains rotating bases 1 and 2, containing teeth 3 around the perimeter, while the teeth of the bases 1 and 2 are engaged. Each energy receiver consists of upper 4 and lower 5 traverses, between which panels 6 are stretched. There is also a central rack 7 with a rotary base 8, bearing assemblies 9 of rotating bases 1 and 2 are fixed on the rotary base. Λ-shaped racks are important nodes of the energy receiver 10, which are fixed on rotating bases 1 and 2, on the wind turbine shown in the drawings there are two rotating bases, on each of which four energy receivers are installed (four panels 6). Each pair of energy receivers is stretched between the lower traverse 5. A pair of Λ-shaped racks 10 mounted on a rotating base intersect at the attachment points 11, and the upper traverse 4 is attached to the vertices 12 of the Λ-shaped racks, vertical racks 13 are installed between the ends of the traverses, wind-receiving surfaces 6 (panels) are attached to it, between which there are tightening springs 14 with leashes 15.

The wind turbine has a central cowl and a guiding stabilizer, fastened to the rotary base 8.

Device operation

When the wind flow is on, the extreme wind receivers move along the wind flow, in particular, the base 1 rotates clockwise, and the base 2 rotates counterclockwise, while the internal wind receivers provide minimal resistance to air flow due to two factors:

- shielding using the screen;

- mutual overlap, which is provided by gearing, the respective receivers are shown by a dashed line in the Central part of figure 1. During operation of the electric motor, sufficient design rigidity of the wind receivers is ensured due to the presence of two power triangles: the lower, as part of the base, and the lower parts of the Λ-shaped struts and the upper, as part of the upper crosshead 4 and the upper sections of the Λ-shaped struts.

The technical and economic advantage of this rotary electric motor is the simplicity and reliability of the main element of wind receivers, due to which their cost is reduced, and it is also possible to build large-scale devices.
