The invention relates to a device for converting wind energy acting on the tethered aircraft, with the transfer of mechanical work on the working body, performing an oscillatory motion.

In the prior art it is known device that converts wind energy into electrical energy with the transfer of mechanical work on the working body, performing an oscillatory motion. (See, for example, patent RF № 2142572, IPC F03D 5/06 "a Device for converting energy of a fluid medium", publ. 10.12.1999, BI No. 34.)

The disadvantage of the Converter is that it has a complex structure. In addition, for obtaining useful work that requires a large pressure fluid medium.

The closest to the technical essence and adopted for the prototype is the energy Converter of the wind acting on the tethered aircraft, with the transfer of mechanical work on the working body, performing an oscillatory motion. (See, for example, patent RF № 2109981, IPC F03D 5/06 "Way of converting the kinetic energy of the velocity pressure of the wind and wind turbine", publ. 27.04.1998, BI No. 12.)

Known Converter includes an aircraft that is holding the rope, working body, reciprocating movement, and a mechanism for performing useful work.

Known Converter provides the use of air flow, usually blowing on top.

The disadvantage of the prototype, as well as analogue, is that at low speed wind pressure received energy is low. In addition, the motion of the wind on the working body has a complex structure and can quickly fail.

The objective of this invention is to provide a Converter of wind energy with a relatively simple design, which is more reliable than the prototype, and can convert the energy of wind blowing, even with a relatively low speed, the oscillating movement of the working body with its subsequent use to generate electricity.

This problem is solved due to the fact that the device converting wind energy into electric, containing aircraft with holding rope, working body, reciprocating movement, and the mechanism that produces useful work, according to the invention the aircraft is made in the form of the body is lighter than air with the aerodynamic profile and has a lower spherical and flat upper surface, with the bottom side of the aircraft coupled with a cable with three radiating from the cable lierow, at the bottom of the rope passes through the fixed funnel receiver with the expanding part, converted to flying the machine, below the funnel-shaped receiver cable coupled to the winch, the working body and the mechanism that produces useful work done in the form of electrical generator with the translational motion of the armature, coupled to the cable below the funnel-shaped receiver with clamp, and a compression spring-tension, compression spring-tension the lower end rigidly connected to a stationary surface.

In the embodiment, the technical solution of the upper surface of an aircraft equipped with a visor extending beyond the perimeter of the top surface,

In the embodiment, the technical solution of the upper part of the aircraft contains, Kiel, the plane of which it is perpendicular and which passes from the center to the periphery.

In the embodiment, the technical solution above the aircraft has a balloon filled with argon and connected to the apparatus using Leer.

In the embodiment, the technical solution of the expanding portion of the funnel-shaped receiver provided with rounded edges.

The presence of the aircraft, made lighter than air and having an aerodynamic profile, consisting of the lower spherical and flat upper surfaces, allows you to set the device at a certain height, where the winds blow, usually, constantly, and their force is much higher than on the surface. When this POPs the W force acting on the device, pulling it up. Aerodynamic profile contributes to the formation of the second force directed downward. The presence of these two forces causes the device to vibrate, setting in motion attached to the apparatus mechanical elements.

A funnel-shaped receiver with the funnel facing the aircraft, with rounded edges, through which passes the cable required for the lateral vibrations of the cable does not affect the working parts of the body.

The use of the working body consisting of an electric generator with the translational motion of the armature, coupled to the cable below the funnel-shaped receiver with clamp, and a compression spring-tension allows you to convert the oscillatory motion of the aircraft into electrical energy.

The presence of the canopy on the upper surface of the aircraft, outside of the perimeter of the top surface, leads to the fact that while driving under the influence of the aerodynamic effect of the device down on the visor will be a force of air resistance tends to turn the device sideways to the direction of vertical movement. Because of this, there will be an additional change in the balance of forces acting on the apparatus, even when a constant and a weak air stream. As a result, by bately process will be more intense, that will increase the energy efficiency of the system.

The application of the keel, the plane of which is perpendicular to the plane of the upper surface of the device, it provides stabilization against wind.

A balloon filled with argon and coupled with the apparatus, increases load-bearing capacity of the device.

Rounded edges extending part of the funnel-shaped receiver and prevent abrasion of the cable when the vibrations of the apparatus under the action of the wind.

The claimed invention is illustrated in the drawings.

Figure 1 shows the principle of a mechanical diagram of the device that performs the function of converting wind.

Figure 2 shows a tethered aircraft with visor, side view.

Figure 3 shows a tethered aircraft with visor and keel, top view.

Figure 4 shows a tethered aircraft with additional balloon.

Converter wind energy into electrical energy is arranged as follows.

Hollow, the aircraft 1 (figure 1) is made lighter than air and has an aerodynamic profile, consisting of the lower spherical 2 and a flat upper surface 3. The apparatus 1 may be internally filled with argon. On the lower side of the device coupled to the cable 4 with three radiating from the cable lierow 5. At the bottom of the rope passing through the same is TKO fixed funnel receiver 6 with funnel with rounded edges (not labeled), converted to the aircraft. The inner surface of the receiver 5 has a special coating that reduces the friction of the rope on his wall. The cable 4 is coupled to the winch 7. In the lower part of the cable 4, below the funnel-shaped receiver 6, the cable has a movable clamp 8 with the clamp bolt 9. Clip 8 with a stiff rod 10 attached to the shaft 11 of the armature 12 with the translational motion. The shaft 11 passes through a stationary bearing sleeve 13. Bottom anchor 11 has a shaft 14 passing through the fixed bearing 15. The bearings 13 and 15 are installed on the same axis. The anchor 11 is located inside the fixed stator 16 of the electric generator. The lower end of the shaft 14 coupled to a compression spring-tension 17, and the lower end of the spring is rigidly connected to a fixed surface (not labeled).

In the embodiment, the technical solution of the upper surface 3 of the aircraft 1 is equipped with a visor 18 (figure 2, 3, 4)extending beyond the perimeter of the top surface, which gives the device an asymmetric shape. The visor is made of a light plastic material and has a small thickness, and its plane is a continuation of the upper surface 3. In addition, the upper part of the aircraft has a keel 19, stabilizing the position of the aircraft relative to the wind. The keel is made of light material, has the h is very thick and goes from the center of the surface 3 to the periphery along the symmetry axis.

In the embodiment, the technical solution of the aircraft 1 has additional balloon 20 (figure 4), filled with argon. The ball is above the aircraft 1 and connected with the latter by rail 21.

Converter wind energy into electrical energy operates in the following manner. Using the winch 4 aircraft lifted to a certain height, separat hoist and fasten clamp 9. The wind is usually blowing on high, the effect on the aircraft 1. The latter due to the aerodynamic effect is determined by the difference in the velocities of wind flow, flowing with the top 3 and the bottom surface 2, will tend to move downward, reducing the tensile force acting on the spring 17. Thus, the apparatus there are two forces, one of which tries to cheer him up, while the second drop down. Due to the fact that the wind is always blowing with variable speed, the apparatus 1 will oscillate up and down. These movements are transmitted through the cable 4, the clamp 9 and the rod 10 against the spring 17 and lead to its alternate compression and tensile strength. Oscillatory movement of the spring causes the anchor 12 can perform a reciprocating motion, which causes the voltage on the windings of the stator 16, which is used to produce electrical energy to the AI. This energy can be used for various household needs.

In the presence of the visor 18 (figure 2, 3) while driving under the influence of wind apparatus 1 down on the visor will act unilaterally force of air resistance, aimed vertically. The machine will turn sideways against the wind, and the action of the aerodynamic effect is weakened. The machine will start to rise again up, striving to occupy its original position. Then the process will be repeated. Thanks this will be an additional change in the balance of forces acting on the apparatus, even when a constant air flow. In the oscillatory process to be performed more intensively, which will increase the energy efficiency of the system.

The application of fin 19 (Fig.2-4), the plane of which is perpendicular to the plane of the upper surface of the device, it provides stabilization against wind.

Balloon 20 (figure 4), filled with argon and coupled with aid increases the load-bearing capacity of the device.
