Description

The invention relates to the field of wind energy and can be used to generate electricity.

A known design of the generator with the location on the tower of a rotary wind wheel equipped with a device for installation in the wind [1].

This wind turbine has a traditional type of tower. Also known is a wind generator [2], which contains a tower, two angled frames connected to a support at the junction with a central rotary support unit, a rotating base of the wind wheel with a horizontal axis, mounted on frames (towers) of frames, supporting trolleys, animators, generators and rotary bases, characterized in that the frames are provided with hinges installed in the central support unit and have guiding mechanisms and a synchronizing device.

The disadvantage of this device is the presence of wind-struts with generators of the traditional classical type that do not provide high linear speeds relative to the movement of the rotor and stator.

Of the known analogues, the closest to the claimed essential features is a segment type wind generator [3], which includes: a tower made in the form of a spatial figure, which is composed of rods that are legs of two rectangular triangles with a common leg (rod) and hypotenuses (rods), while an arcuate rod connects the vertices of these triangles. A continuation of the upper rod is a bearing assembly in which the hub of a wind wheel rotates, having blades that are connected by a ferromagnetic rotor plate, which is also the end aerodynamic washer. Rotor plates (rotor elements) enter into periodic magnetic contact with a stator element mounted on a curved rod. The rods have a jumper in the middle part, on which the steering wheel is mounted, which is also fastened to the rod. Arcuate rods are connected to a support mounted in a hinge mounted on a base plate.

The disadvantage of this device is the large overall dimensions and the lack of drilling protection.

The invention is aimed at reducing dependence on gusts of wind gusts.

This is achieved by the fact that the segment type wind turbine contains a tower, a rotating base, a wind wheel with a horizontal axis, a generator with stator and rotor elements and a tail element. According to the invention, the rotating base is provided with rotating rollers which are mounted outside the central pipe, on the front end of which the generator is fixed, and a wind wheel at the rear end, with a central shaft mounted in bearings in the central pipe, which is attached to the rotating base at the front and to the tail base at the rear. element.

The achievement of the technical result is due to the hollow execution of the central pipe 7, inside of which a central rod supporting the tail element is mounted on the bearings.

The invention is illustrated by drawings, in which Fig. 1 shows a wind power unit, a side view in section, in Fig. 2 is a front view, in Fig. 3 is a section in the middle of the central pipe and along the upper roller, in Fig. 4 is a section in supporting rotating commercials.

The segment type wind power unit includes a tower 1, fastened with an arm 2, on which stator elements are mounted - stator magnetic circuits 3 with windings 4 and a central rod 5, on which bearings 6 are mounted, and on them, in turn, a central tube 7 is mounted.

At the front end of the central pipe, with the help of spokes 8, a generator rim 9 with rotor elements 10 is strengthened, which can be either ferromagnetic teeth (inductor design) or permanent magnets (classic synchronous generator design). The central pipe 7 rests on the rotating rollers 11 mounted on the rotating base 12. From above, the pipe is pressed by a roller 13 mounted in the upper bracket 14. At the rear end of the central pipe 7, the rim 16 of the wind wheel is mounted using spokes 15, on which the elastic wheels 17 are mounted blades 18. At the rear end of the central rod 5, a tail element 19 is mounted, fastened through holes 20. The position of the blades during a gust of gust is shown in dotted line in FIG. In the inductor design there are stator excitation sources (magnets) 21.

Description of the operation of the device. The incident wind flow directed from Fig. 1 from left to right drives the wind wheel by acting on the blades 18. The movement using the spokes 15, the central pipe 7, the spokes 8 and the rim 9 is transmitted to the rotor elements 10 of the generator, which, interacting with the magnetic systems 3 induce EMF in the coils of 4 stator. When changing the direction of the wind, the wind effect through the tail element 19 is transmitted to the central shaft 5, bearings 6, the central pipe 7, rollers 11, to the rotating base 12, which orientes the unit to the wind.

Protection from gusts of gusts is carried out by turning the blades 15 in radial planes in the elastic hinges 17 to the position shown by a dotted line in FIG.

The advantage of this unit is, in addition to resistance to storm gusts of wind, the optimal weight distribution on a rotating base, which consists in the fact that the mass of the generator is balanced by the mass of the wind wheel with the tail element.
