ВЭПГ-3 - wind power station sailing, on which the axis of rotation of a four-shaft flexible shaft of wind turbines and generator lies on one vertical line. The generator is installed below, and above the generator - wind turbines, strung on four cables. These cables are suspended to the bearing, and the bearing to the horizontal cable stretched on the two masts, each windmill is equipped with two sails tied with laces to the holes on the edges of the two rails. Rays 2 are rectangular in the form of plates and in the center - one large hole (diameter 30 mm) and eight small holes located in pairs in radial directions from the axis of rotation of the shaft and at the same distance from the center and from each other. These eight holes serve to secure the two rails 2 to each other, and the edges 2 must be positioned so that they are displaced relative to each other along the axis of rotation of the shaft by an angle of 90 ° . Two sails stretched on the rims form two half-cylinders and are arranged so that, using active and reactive wind action, they receive from it a pair of forces, causing a flexible shaft to rotate, which transmits the rotation to the generator. At the edges of each edge 2, closer to the center, four parallel cutouts are made, two on each side, when the rails are displaced 90 ° along the axis of rotation, when four of them are bound to each other, bounded by these cutouts. In these four holes there are four cables of the flexible shaft, but the two axes can move up and down on them by means of a halyard that serves to stop the flexible shaft. One end of this halyard, anchored in the center of the upper ridge, of the upper propeller, holds all propellers on the shaft. The other end of the halyard, passed through the central holes of all rails, is fixed to the clamp, fixed at the bottom of the flexible shaft. With complete weakening of the end of the halyard, all the propellers, sliding along the four cables of the flexible shaft, will gather in the "accordion" on the lower platform above the generator and the shaft will stop. The generator can also be stopped using the clutch, and the flexible shaft will continue to rotate at idle speed. The technical result consists in increasing the efficiency of the installation, simplifying the design.

DESCRIPTION OF THE INVENTION

The invention relates to wind energy, in particular to wind power plants.

A wind power station with a sailing wind is known, containing at least two sailing windmills.

The purpose of the invention is to increase the efficiency of the installation, simplify the design.

The goal is achieved by the fact that under the action of the wind the generator rotates by sailing propulsors, which are fixed on a flexible vertical shaft located on the suspension. A simple system for stopping the rotation of the shaft is provided.

WIND POWER STATION SAIL-3 (VEPG-3)

In Fig. 1 shows the appearance of VEGG-3; in Fig. 2 - wind turbine, top view.

VEHG-3 consists of a flexible shaft 1, consisting of two parallel cables (located vertically), transmitting the rotation from the wind turbine to the generator. Each windmill consists of two rails 2, which are rectangular plates with rounded two corners and with four lateral cutouts 3. A hole 4 is made in the geometric center of each edge 2. Two sails 5 are tensioned between the two races 2, the edges of which are laced at the edges 2 in holes 6 at its edges using nylon strings 7 (see Figure 2). Suspension of it on the shaft is carried out with the help of a tether 8 (see Figure 1). The Fal 8 is thrown through the stationary block roller 9. One end of the 8, passed through the hole 4, is tied with a "dead" loop by the length of the thick wire 10. The other end of the phal 8 passes through the holes 4 of the two rails 2, and the wind turbine starts to rise. Similarly, the second propeller is also assembled. But it is suspended - it is already attached to the lower edge of the first one, i.e. the upper propulsor. This binding is carried out by laces through eight small holes located in pairs in radial directions from the axis of rotation of the shaft and at the same distance from the center and from each other. These edges 2 should be offset relative to each other by an angle of 90 ° (see Figure 2), where the lower thruster is shown in dotted lines. With this offset, both shaft cables 1 will be fixed in the cutouts 3 in this pair of rails 2, i.e. rai 2, tied to each other, because at such a 90 ° offset, in this pair of tethered rails 2 four holes are formed, located at the corners of the square, using these four holes must be along the diagonals of the square. The second end of the tether 8 is passed through all the holes 4 of all the rails 2, and after successively assembling all the propellers and successively lifting them along the ropes of the shaft 1 upward beyond the tether 8, its end is sealed by the clamp 11 reinforced on the shafts 1 in the lower part thereof and shaft 1 will rotate under the influence of the wind, with the weakening of the end of the fal 8, all the sails 5 will be added "accordion" on the platform 12 above the generator, and the shaft 1 will stop. However, the generator itself can be stopped using a clutch, disengaging the generator shaft from the flexible shaft, and the generator shaft stops and the flexible shaft continues to spin at idle speed. The clutch 19 and the gearbox 20 are installed above the generator.

The number of propulsors, even on the most low-power VEPG-3, should be at least two, since in this case there will be no "dead point" when rotating under the influence of wind. In Fig. 2 it can be seen that two sails 5 in the form of two half cylinders receive from the wind a pair of forces from the active and reactive actions of the wind, causing the shaft 1 to rotate. At the top, the shaft 1 is connected to the bearing 13. The bearing 13 is connected to a horizontal cable 14. The cable 14 is tensioned between two masts 15 (see Figure 1). The masts 15 can be assembled from pipes 16 held in a vertical position (at the joints) by pipe couplings 17 and cable rods 18.
