Description

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

Known wind generator containing a tower with rotary wind wheels, a device for installing in the wind, as well as rotors and stator with windings [1].

The disadvantage of this device is the increased mass of the rotor, which to increase productivity must have a large number of blades with rotor elements, which is practically unacceptable in the case of large-diameter wind wheels.

Of the closest to the claimed essential features is a wind generator [2], containing a tower with rotary wind wheels, a wind installation device, rotors and stators with windings, the rotors are made in the form of aerodynamic washers, and the wind wheels are connected by flexible elements, which allows for sequential operation each of two wheels on one stator.

The disadvantage of this device is the ability to work with wind wheels of only one pair, which in the case of high-speed wheels leads to unjustified energy losses in low-potential winds, and in the case of low-speed wheels leads to their underutilization in strong winds, which generally reduces the operational characteristics of the device.

The technical result, which consists in increasing the operational characteristics through the use of two pairs of wind wheels - horizontal and vertical - is ensured by the fact that in a segmented wind generator containing a magnetic field source, a working coil and magnetic circuits, characterized in that according to the invention the magnetic circuits are made in the form two symmetrical T-shaped plates located in two main parallel planes and in the form of two asymmetric T-shaped plates, and asymmetric The plates are located perpendicular to the main planes, with each vertical column of the asymmetric plate attached to one of the columns of the symmetrical plates, and a magnetic field source and a working coil are installed between these columns.

The invention is illustrated in the drawing, where figure 1 shows a General front view of a wind generator, figure 2 is a top view. On a larger scale, the generator stator is shown in FIG. 3 is a front view, in FIG. 4 is a side view, in FIG. 5 is a top view, in FIG. 6 is a rear view, in FIG. 7 a T-shaped symmetrical plate is shown separately. magnetic circuit, in Fig.8 - two asymmetric plates.

The segment type wind generator consists of a tower 1, wind wheels having a rim 2 with ferromagnetic rotary segment elements 3. Bicycle type wind wheels have spokes-blades 4, wind wheels connected by a flexible element 5 (for example, a chain or a toothed belt), which covers pulleys 6 mounted on the hub . In the center, between vertically mounted wind wheels and simultaneously between horizontally mounted wind wheels, a stator 7 is installed. A rotating base 8 is installed on the tower, and the flexible element is equipped with a tensioning device - a roller 9 with a spring-loaded lever 10. The rotating base is equipped with a tail 11, a transverse traverse 12, on the ends of which are mounted bearing units 13.

Consider the stator device in more detail (Figs. 3-8). Its base is composed of four charged magnetic cores made in the form of T-shaped plates. Of these, two plates 14 and 15 are symmetrical - see Fig. 7 and two plates 18 and 19 - asymmetric - Fig. 8. There is a magnetic field source - a central core 16 with a working coil 17. In the rack of asymmetric plates, holes 23 are made through which non-magnetic mounting bolts 20 are passed. There is also a central mounting non-magnetic bolt 21, tightening plates 14 and 15 and core 16. In the racks of symmetrical plates holes 22 for the passage of bolts 20 and a Central hole for the bolt 21 are made - see Fig.7.

The operation of the device. Under the influence of the wind flow on the blades 4, the wind wheel, and therefore the rim 2 come into rotation. The rotor elements 3 alternately enter into magnetic interaction with the pole pieces and, in accordance with the principle of operation of the inductor generator, the magnetic flux of the field sources 6 is switched - permanent magnets made in the form of washers with holes for the central non-magnetic bolt 21.

The technical advantage of this wind generator is that due to the design of the magnetic cores in the form of four spatially arranged T-shaped plates, it was possible to introduce into the magnetic interaction not only a pair of horizontally mounted wind wheels, but also a pair of vertically mounted wind wheels, which, in turn, allowed almost double the performance of this generator compared to the prototype.

The use of this wind generator allows to obtain stable performance characteristics, namely, that the generation of voltage occurs during winds of any intensity, since four high-speed wheels operate on the same load in turn, which leads to a decrease in the starting moment while maintaining all the main indicators.
