DETAILED DESCRIPTION OF THE INVENTION
The gearless wind turbine contains a vertically mounted magnetoelectric generator with a rotor 1 (Figs. 2, 3, 6) and a circular stator 2 (Figs. 1, 2, 3, 6, 7) and a flow conditioner made in the form of four identical interconnected shells 3 (Figs. 1-6) having on the front side a recess tapering with a tilt towards the center and configured to concentrate the air flow to the front face of the shells 3 (Figures 1-6) into a bundle. In this case, the shells 3 (Fig. 1-6) form a closed contour along the perimeter, conjugated to each other sides. The shells 3 (FIGS. 1-6) are fixed from below on the support 4 (FIG. 1). In the left upper and lower right corners, on the front side of each shell 3 (FIG. 1) having a recess with a slope to the center, equally located channels 5 (FIGS. 1, 4, 5) of the return return of the air flow are mounted. The rotor 1 (Figures 1, 3, 6) consists of a shaft 6 (Figures 1, 2, 3, 6, 7), in which, depending on the diameter dimensions, six to an equal number of angled blades 7 (Fig. 2, 3, 6). In this case, the excitation coil 8 is fixed on the axial straight part of each blade 7 (Fig. 2, 3, 6) (Fig. 2, 3, 6). And each curved part of the blade 7 (FIG. 2, 3, 6) is made to the axial part of the blade 7 (FIG. 2, 3, 6) at an angle. The circular stator 2 (FIG. 1, 2, 3, 6, 7) comprises at least at least eight diffusers 9 (FIGS. 1, 2, 3, 6, 7) disposed in a circle and serving for passage of air currents. Moreover, the larger the dimensions of the circular stator 2 (Figures 1, 2, 3, 6, 7,), the more the number of diffusers 9 (Figures 1, 2, 3, 6, 7) contains at least not less than sixteen magnetic plates 10 (FIGS. 2, 3, 6) fixed two in each diffuser 9 (FIGS. 1, 2, 3, 6, 7). The magnetoelectric generator is made up of individual, sequentially installed stages, at least three or more, including the stages 11 (FIG. 7) of the rotor 1 (FIGS. 2, 3, 6) and the facilitating stator stages 2 (FIGS. 2, 3, 6, 7), with the possibility of composing the steps of the magnetoelectric generator in a vertical plane, at least three to one number. The stages of the magnetoelectric generator are designed to be installed in a vertical plane, both in the form of separate independent steps, and in the form of dowels secured to each other (not shown in the drawing). The increase or decrease in the number of stages 11 (Fig. 7) in the magnetoelectric generator respectively increases or decreases the rotational speed of the rotor 1 (Fig. 2, 3, 6), its electromotive force, and changes the power of the magnetoelectric generator. With a three-stage magneto-electric generator, the first-middle stage 11 (Figure 7) is located inside four interlocking shells 3 (Fig.1), having a depression inclined toward the center, one of which, depending on the direction of the wind, receives airflow. The second upper stage 12 (FIGS. 1, 7) is located in the cavity 13 (FIG. 1) between the roof 14 (FIG. 1) of the wind turbine and the upper rear surface 15 (FIGS. 1, 2) of the shells 3 (FIGURES 1, 2 ). The third, lower stage 15 (FIG. 1, 7) is located in the cavity 17 between the support 4 (FIG. 1) and the lower back surface 17 (FIG. 6) of the shells 3 (FIG. 6). The wind turbine has at least sixteen valves containing the flaps 18 (Fig. 1-6) of the valves and chamber 19 (Fig. 1-6).
To collect the wind into the beam, two equally located valves are provided on each front front side of all four shells 3 (FIGS. 1-6) of the middle stage 11 (FIG. 1). One valve 20 (FIG. 1) is located in the lower left corner of the front front side of the shells 3 (FIG. 1), opposite the opening of the air return channel 5 (FIG. 1), mounted in the upper left corner of the front front side of the shells 3 (FIG. .1), and the second valve 21 (Figure 1) is located in the upper right-hand corner of the front front side of the shells 3 (FIG. 3), opposite the opening of the return air channel 5 (FIG. 1), mounted in the lower right-hand corner of the front front side Of the shells 3 (FIG. 1).
In the cavity 13 (FIG. 1) of the second upper stage 12 (FIG. 1) of the magnetoelectric generator, four valves 22 are formed between the roof 14 (FIG. 1) of the wind turbine and the upper rear surface 15 (FIG. 2) of the shells 13 (FIG. 2) 2) smoothly mating with the internal cavity of the upper channels 5 (FIG. 1) of the return return of the air flow. In the cavity of the third stage 16 (FIG. 1, 7) of the magnetoelectric generator, between the support 4 (FIG. 1) and the lower rear surface 17 (FIG. 6) of the shells 3 (FIGS. 1-6), four valves 23 (FIG. 6 ), Smoothly conjugated to the internal cavity of the lower channels 5 (FIG. 1) of the return return of the wind flow.
The wind turbine is designed in such a way that the air flow of the wind in each stage returns to its original position and thereby increases the efficiency of the gearless wind turbine in the case of a small wind. The wind turbine works as follows.
The air flow, depending on the direction of the wind, falls on one of the four shells 3, presses on the flaps 18 of the valves 20, 21 in the first middle stage 11 of the magnetoelectric generator and enters the middle valves of the chamber 19, gathering in the beam where the diffusers 9 of the stator 2 First stage 11 of the magnetoelectric generator. Then, the air stream collected in the beam hits the blades 6 of the rotor 1 of the first middle stage 11 and drives it into rotation. In this case, the valve flaps 20, 21 of the first stage 11 of the magnetoelectric generator are open and the return air streams of the first stage 11 open. The remaining flaps 18 of the chamber 19 and the return air return channels 5 of the first middle stage 11 are closed. The air flow, pressing the rotor 1 of the first stage 11 of the magnetoelectric generator, enters the diffusers 9 of the stator 2 of the lower stage 16 and the upper 12 and then falls on the blades 6 of the rotor 1 of the lower 16 and upper 12 stages of the magnetoelectric generator and drives the rotor 1 to the lower upper 12 stages . Simultaneously, the air flow opening the right upper flap 18 and the left lower flap 18 of the first stage 11 through the chambers 19, respectively, enters the lower and upper return air flow channels 5 and intensifies the pressure on the blades 6 of the rotor 1, increasing the speed and allowing the operation of the wind turbine at Wind speed V = 1 m / s, due to the fact that the headwinds are collected in a bundle in the shells 3 and the reverse-return system of return air return channels 5 return to the original direction. By increasing the dimensions and number of steps of the magnetoelectric generator, the wind turbine can achieve the desired power. When the rotor 6 rotates, the excitation coils 8 on the blades 7 interact with the magnetic plates 10 of the stator 2 produce a current and this gives a gearless windmill, i.e., a magnetoelectric generator with a rotor 1 and a stator.
