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 installing on the wind [1], containing the tower of the traditional type. Its disadvantage is significant weight and dimensions.

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 on the left side, 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 a segment type wind generator containing a fixed base (mast), a rotary base (rack - head), a wind wheel with rotor elements, an arc stator, a tail element, shock absorbing elements and hinges, according to the invention, has rotary elements made of a W-shaped shape, and the magnetic circuit of the stator element consists of an L-shaped packet having an air gap with a horizontal portion of the rotor element and a core packet having an air gap with a vertical portion rotor element, while the tail element is mounted on the axis of the wind wheel.

The achievement of the technical result is due to the installation of a wind wheel behind the tower, while the mass of the tail element is balanced by a segmented stator having extended dimensions along the center axis line.

The invention is illustrated by drawings, where figure 1 shows a wind generator (side view in section), figure 2 is a front view.

The wind generator contains a rotating rack - tip 1, on which, using nuts 2, a central rod 3 is fixed, on which the wind wheel bush 5 is mounted, on which, in turn, by means of spokes 6, a rim 7 with rotor elements 8 and an arm 9 is fixed, supporting elastic hinges 10 with blades 11. The central rod is provided with a bar 12. The supporting tail element 13 is connected to the strut 14. The stator includes the same type of segment type elements, each of which contains a L-shaped magnetic core 15, a permanent magnet t 16, rod package 17, coil 18. All elements are mounted on two mounting sections 19 and 20, located symmetrically on the right and left side of the rack - head 1, which rotates in a bearing mounted in the upper part of the mast 21. As can be seen from FIG. .1, the rotor element 8 has a W-shaped shape, while the L-shaped stator magnetic circuit 15 has an air gap 22 with a horizontal section of the rotor element, and the core package 17 of the stator magnetic circuit has an air gap 23 with a vertical (left in FIG. 1) section Sh-shaped rotary ele enta 8. The central rod 3, which is the axis of the wind wheel, has a connection to the bar 12, which plays, along with the strut 14, the fastening of the tail element 13. The strut 14 with its lower end is mounted on the rack 1 (not shown in Fig. 1 due to the lack of places).

The operation of the device. With weak gusts of wind, the blades 11 with the help of elastic hinges 10 are installed vertically (figure 1). The wheel, being guided by the wind with the help of the tail element 13, enters into rotation, the elements 8 break the gaps 22 and 23, the magnet 16 induces an emf in the coils 18. With gusts of gusts, it is possible to fold the blades, that is, turn them in hinges 10 with deformation of the springs inside them, up to a horizontal position (Fig. 1, dotted line).

The advantage of this wind generator is the realization of the possibility of passing gusts without significant impact on the power structure.
