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, air ducts mounted 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, moreover, according to the invention, the air ducts are lateral in the form of three sections - receiving, direct and arched baskets, the last of which is oriented to the blades of the 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, and, according to the invention, 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 rods with the corresponding edge of the curtains of the opposite columns, while the columns are hollow and equipped with windows with jumpers, the windows are located on one side of the columns, and uschey 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 wind turbine containing rotating bases with energy receivers, a central rack with a rotating base on which rotating bases are mounted, and, according to the invention, the energy receivers are made in the form of Λ-shaped racks in which the lower fasteners are installed traverses that are bonded to the bases, and on the tops of the racks are the upper traverses, the inner ends of which are fixed to the rods, and the latter are installed in the centers of the rotating bases, each energy receiver consists of upper and lower traverses, between which the panels are stretched.

The technical result, which consists in simplifying the design and increasing reliability, consists in the possibility of using passive energy receivers with the main element - the panel.

The invention is illustrated by drawings, where in FIG. 1 shows a rotary electric motor, a top view, in FIG. 2 is a front view, in FIG. 3 is a side view, in FIG. 4 is an isometric view 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 mounted on rotating bases 1 and 2, on the wind turbine shown in the drawing there are two rotating bases, each of which has four energy receivers. Between the lower fasteners of the Λ-shaped struts laid lower traverse 5, which are fastened to the base. The upper traverses 4 are fixed in their middle at the tops of the Λ-shaped racks, and with their inner end on the rods 11 installed in the center of the rotating bases.

The wind turbine has a central fairing 12 and a guiding stabilizer 13, fastened to the rotary base 8.

Device operation

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

- shielding using the central fairing 12;

- mutual overlap, which is provided by gearing, the respective receivers are shown by a dotted line in the central part of FIG. 1. During the operation of the wind turbine, sufficient design stiffness of the energy receivers is ensured due to the presence of a power triangle in each: Λ-shaped strut - upper crosshead - rod 11 with base and lower crossarm 5.

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