The case of the wind turbine is made in the form of a rigid frame containing a lower right-angled metal cross 2 (Fig.1,2,4) and an upper, right-angled metal cross 3 (Fig.1-3) and four triangular shapes, in the form on top of the frame formed by interconnected vertical rectangular shapes of the barrier walls, including the inner barrier wall 4 (Fig.1-4), the outer barrier wall 5 (Fig.1-4) and the rear barrier wall 6 (Fig.1-4) which are fixed on a metal x stands 7 (fig.1,4). Directed from the center of the side of the bottom, located at right angles to the metal cross 2 (Fig.1,2,4) and the upper metal cross 3 (Figs. 1, 3, 4), are rigidly fixed by their ends, mainly by welding 8 (Fig. 3, 4) at an acute angle formed by the inner wall 4 (Figs. 1-4) and the outer wall 4 (Figs. 1-4) on each of the four, triangular in shape, in a plan view, frames. The lower, right-angled metal cross 2 (Figs. 1,2,4) and the barrier walls 4-6 (Figs. 1-4) of a triangular shape, in a plan view, of frames made elevated above a central hollow support 9 ( Fig. 1,2.-4) mounted in the center of the square shape of the base 1 (Fig. 1,2). Inside the central, made hollow bearings 9 (Figs. 1, 2, 4), an electric generator 10 (Figs. 1, 2, 4) is installed, the vertical shaft 11 (Figs. 1-4) of which is mounted on ball bearings (not shown in the drawing) in sleeves 12 (Figs. 1-4) mounted in holes (not shown in the drawing) made in the central part of the lower metal, located at right angles to the cross 2 (Figs. 1, 2, 4) and the upper, located at right angles metal cross 3 (figure 1, 3, 4). On the vertical shaft 11 (Figs. 1-4) of the generator 10 (Figs. 1, 2, 4), the blades 13 (Figs. 1-4) are made, made of a rectangular flat shape, which are located vertically between the lower metal cross 2 (Fig. 1 , 2, 4) and the upper metal cross 3 (Fig. 1, 3, 4). The inner barrier wall 4 (Figs. 1-4) of each of the four frames, triangular in shape, in a plan view, is located at right angles, on the one hand, to the

The wind turbine operates as follows.

At a minimum wind speed of 0, part of the air flow enters the blades 13, and most of the air flow enters the outer barrier wall 5 and the rear barrier wall 6, each of the four frames, triangular in shape, from above, which are mounted on metal racks 7 and is guided these walls onto the blade 13 (shown by arrows in the drawing. The blades 13 are made of rectangular flat shape and are located vertically between the lower, right-angled metal cross 2 and the upper The metal cross 3, laid at right angles, allows full use of the air flow.The air flow entering the blades 13 rotates them and the vertical shaft 11 on which they are mounted, the electric generator 10, which generates an electric current .. Barrier walls of each of the four frames, triangular , the top view several times increase the air flow entering the blades, which can dramatically increase the efficiency of the wind turbine. The outer barrier wall 5 of the triangular, in a top view, frame at the interface with the lower, located at right angles metal cross 2 and the upper metal cross 3, is made at an acute angle of 15 to 25 degrees to the inner barrier wall 4 of a triangular shape, as on top of the frame, which creates pressure and spins the blades 13 of the air wheel in one direction and does not create pressure from the back of each blade 13. The openings formed by the walls 4-6 are located between the acute angle of one of the four yreh frames and the inner skirt wall 4 adjacent triangular shape in a plan view, the frame are formed with the same side of the barrier walls 4-6 triangular shape in a plan view,

frames so that the direction of the flow of air passing through any of the openings was directed to the blades 13 of the wind wheel, with the possibility of unwinding in the same direction. Additional removable barrier walls 14 of a triangular shape, in a plan view, of frames made with the possibility of their fastening from below to the main barrier walls 4-6 of a triangular shape, in a plan view, of frames, in the summer, are installed between the main barrier walls 4-6 and the base 1 than provide an increase in air flow on the blades 13 and due to this increase the efficiency of the wind turbine. The implementation of the aluminum blades 13, the lower, located at right angles to the cross 2 and the upper, located at right angles to the cross 3, the main barrier walls 4-6 and additional barrier walls 14, four, triangular, in a plan view, frames, racks 7 and central support 9, reduce the weight of the design of the wind turbine
