FIELD: power industry.

SUBSTANCE: method to convert wind energy into useful energy by acting on strings of incoming air flow. Oscillations of strings under action of the air flow are amplified owing to enlarging their surface by hanging cloths onto them. Conversion of energy of oscillations into useful energy is concentrated at one point between the centre of strings and the point of the surface, which is a projection of the centre of strings onto the above surface. Strings are located so that their centres cross at one central point.

The invention relates to the field of wind energy, and more specifically, to a safe wind converters and can be used in offline sources, converts the energy of wind flow into useful energy.

There is a method of converting wind energy into useful energy, in which micropreemie produce electricity due to fluctuations oppontent on vertical racks strings connected by rods with spring-loaded movable part of the linear generators (EN 2391556 C1, 10.06.2010).

The disadvantage of this method of converting wind energy into useful energy is that its efficiency is low. In addition, its structure is complicated, and requires to take into account the direction of the wind.

As a prototype the selected conversion of wind energy into useful energy, is described in patent RU 2244850 C2 (20.01.2005).

In the known method useful energy generated by the vibration of the strings located in the oncoming flow of air, by placing the electrically conductive strings in a magnetic field.

The advantage of the prototype is the simplicity of the design.

Its disadvantage is low efficiency. In addition, to generate a signal, it is necessary to take into account the wind direction, which adds complexity to the device.

The objective of the invention is the fast creation method, providing useful energy from the air flow, which allows to simplify the construction of devices that are widely using wind energy.

The technical result is to increase the efficiency and reliability of the conversion of wind energy into useful energy, made by this method.

Additional technical result is also providing flexibility and simplifying the design.

The technical result is achieved due to the fact that in the method of converting wind energy into useful energy through action on the strings of air flow according to the invention the vibration of the strings under the action of air flow increase due to the increase of their surface by hanging their banners, and the conversion of vibrational energy into useful energy concentrated in one location between the center of the strings and the surface point, which is the projection of the center of the strings to the specified surface

Strings can be positioned so that their centers intersect at one Central point.

Hanging on the strings of panels allows to provide the vibration of the strings under the action of even a weak wind and at the same time allows to simplify the design, made by this method.

The conversion of vibrational energy into useful energy in a single Central point on which allows to create compact inverter the generator of useful energy.

The method of converting wind energy into useful energy is illustrated by four figures.

Figure 1 presents a General view of micropreemie with panels, hung on strings.

Figure 2 shows the energy Converter made in the form of a linear electric generator.

Figure 3 is sketched circuit diagram of the Converter of energy fluctuations.

Figure 4 shows verapramil, the strings which are located on the diameter of the circumference of the Hoop so that they overlap in the center, top view.

Vitroplant ensuring implementation of the proposed method of converting wind energy into useful energy, is made as follows. On the surface 1 (1) set of rack 2. Between the posts 2 a taut string 3, which is to increase the surface effects on the strings of the airflow hinged panels 4. In turn, the upper edges of panels 4 contain scenes (not shown), in which vzduvaetsja strings 3. Panel 4 hang evenly so that they divided the string between the posts 2 equal halves. Panel 4 should be fixed in its position on the strings 3 to prevent possible displacement along the strings. In order for the power Converter to perform a compact location transformed into the La concentrate in one place, namely, between the center of the strings 3 and the point which is the projection of the center of the strings on the surface 1. The energy Converter of oscillation is made on the basis of the linear electric generator 5.

If the strings 3 are placed in several parallel rows, each such string must have its own energy Converter hesitation.

In turn, the linear electric generator 5 is set so that its stator 6 (2) articulated with the surface 1 via a ball joint 7, and the secondary body - runner 8 is attached directly to the spring stretch marks 9 and 10. The articulated joint 7 with the surface at the point which is the projection of the center point of the string to the surface. And stretching 9 is attached to the hinge 7, and stretching 10 is located between the center of the string 3 and the upper point of the secondary body - runner 8.

On the circuit diagram (figure 3) output terminals of the linear electric generator 5 is connected to a full wave bridge rectifier 11. Parallel to the DC circuit of the rectifier is connected to the capacitor 12 and the battery 13. The output circuit has a Converter 14 DC to AC frequency.

In version strings 3 micropreemie are located on a diameter of the circumference of the Hoop 16 (figure 4) so that they overlap in the center, where they fasten. Thus t is buesa only one linear electric generator 5, placed in the center of the Hoop 16, which is installed as shown in figure 2. Banners must be hung evenly so that they divided each string between the posts 2 equal halves.

Devices that implement the method of converting wind energy into useful energy, work as follows. The influence of wind on the structure shown in figure 1, panel 4 begin to flutter. Their movement is transmitted to the string 3, and the last comes in a reciprocating motion. This movement is perceived by the generator 5. Fluctuations runner 8 relative to the stator 6 generates the alternating voltage, which bridge rectifier 12 is converted into direct current.

The peculiarity of this method is that due to the panels the total surface of the strings increases many times. This system has ultra-high sensitivity to wind and reacts practically in a small dependence on the direction of wind flow.

A variant in which the strings are arranged on the diameter of the circumference of the Hoop 16 (4), gives the opportunity to react system for wind load regardless of the direction of the wind, and at the same time, the total realizable energy increases in proportion to the number of strings. Thus the deviation of the generator 5 from the axis, soy is inauma the center of the circle of the Hoop 16 and the location of its connection with the hinge 7, will be minimal, leading to greater system reliability and increase its service life.

1. The method of converting wind energy into useful energy through action on the strings of air flow, characterized in that the vibration of the strings under the action of air flow increase due to the increase of their surface by hanging their banners, and the conversion of vibrational energy into useful energy concentrated in one location between the center of the strings and the surface point, which is the projection of the center of the strings to the specified surface

2. The method of converting wind energy into useful energy according to claim 1, characterized in that the strings are positioned so that their centers intersect at one Central point.
