VEPG-3 is a wind powerhouse sailing, on which the axis of rotation of the four-rope flexible shaft of wind-driven generators and the generator lies on the same vertical line. The generator is installed below, and above the generator - wind turbines, strung on four cables. These cables are suspended from the bearing, and the bearing is suspended from a horizontal cable stretched on two masts, each wind turbine is equipped with two sails tied with laces to the holes on the edges of two boards. Rhea 2 has a rectangular shape in the form of plates and in the center - one large hole (diameter 30 mm) and eight small holes, arranged 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 are used for corded binding of two rails 2 to each other, yards 2 should be positioned so that they are displaced relative to each other along the axis of rotation of the shaft through an angle of 90 o . Two sails stretched on the yards form two half-cylinders each and are arranged so that, using the active and reactive actions of the wind, they receive a couple of forces from it, causing the flexible shaft to rotate, which transmits the rotation to the generator. On the edges of each yoke 2, closer to the center, four parallel cutouts are made, two on each side, when the ray is displaced by 90 o along the rotation axis during binding to each other, four holes are formed, bounded by these cutouts. In these four holes there are four cables of the flexible shaft, but yards 2 can be moved up and down along them with the help of a file, which serves to stop the flexible shaft. One end of this halyard, secured in the center of the upper yoke, the upper propulsor, holds all the propulsive devices on the shaft. The other end of the halyard, passed through the central holes of all the rails, is fastened to the clip, which is fixed in the lower part of the flexible shaft. With the complete loosening of the end of the halyard, all the propellers, sliding along the four cables of the flexible shaft, will assemble into an "accordion" on the lower platform above the generator and the shaft will stop. The generator can also be stopped using a clutch, while the flexible shaft will continue to rotate at idle speed. The technical result is to increase the efficiency of the installation, simplifying the design.

DESCRIPTION OF THE INVENTION

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

Known wind power sailing, containing at least two sailing wind turbines.

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

This goal is achieved by the fact that under the action of the wind rotates the electric generator with sailing propellers, which are mounted on a flexible vertical shaft, located on the suspension. Provides a simple system for stopping the rotation of the shaft.

WIND POWER PLANT SAILING-3 (VEPG-3)

FIG. 1 shows the appearance of VEPG-3; in fig. 2 - wind turbine, top view.

VEPG-3 consists of a flexible shaft 1, consisting of two parallel cables (arranged vertically), transmitting rotation from wind turbines to the generator. Each wind turbine consists of two rey 2, which are rectangular plates with rounded two corners and four side cuts 3. There is an opening 4 in the geometric center of each yoke 2. Two sails 5 are stretched between two yards 2, the edges of which are laced with yarn 2 holes 6 on its edges with the help of nylon laces 7 (see Fig. 2). Its suspension on the shaft is carried out with the help of halyard 8 (see Fig. 1). The halyard 8 is thrown over the stationary block roller 9. One end of the halyard 8, passed through the hole 4, is tied with a "dead" loop over the thick wire 10 section. The second propulsion unit is similarly assembled. But it is suspended - it is already attached to the bottom of the first 2, i.e. upper propulsion. This binding is carried out by laces through eight small holes, arranged 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 yarns 2 relative to each other should be shifted by an angle of 90 o (see Fig. 2), where the lower propulsor is shown in dotted lines. With such an offset, both cables of shaft 1 will be fixed in notches 3 in this pair of plane 2, i.e. ray 2, tied to each other, because at this 90 o offset in this pair of tied to each other rey 2, four holes are formed, located at the corners of the square, these four holes must be used along the diagonals of the square. The second end of the halyard 8 is passed through all the openings 4 of all rey 2, and after successively assembling all the thrusters and successively lifting them along the cables of the shaft 1 upwards by the halyard 8, their end is buried behind the clip 11 fastened to the cables of the shaft 1 at the bottom and shaft 1 will rotate under the action of the wind, with the weakening of the end of the halyard 8, all the sails 5 will form an "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 with a flexible shaft, and at the same time, the generator shaft will stop and the flexible shaft will continue to rotate at idle speed. A clutch 19 and a gearbox 20 are installed above the generator.

The number of propellers even on the most low-power VEPG-3 should be at least two, since in this case there will be no "dead point" during rotation under the action of the wind. FIG. 2 that two sails 5 in the form of two semi-cylinders receive from the wind a couple of forces from the active and reactive actions of the wind, forcing shaft 1 to rotate. At the top, shaft 1 is connected to bearing 13. Bearing 13 is connected to horizontal cable 14. Cable 14 is tensioned between two masts 15 (see Fig. 1). Mast 15 can be assembled from pipes 16, held in a vertical position (at the joints) by pipe couplings 17 and cable extensions 18.

CLAIM

Wind power station sailing VEPG-3, containing at least two sailing wind turbines, characterized in that wind turbines consist of two rectangular plates, parallel cables of a flexible shaft, transmitting rotation from wind turbines to the generator, a flexible shaft connected with yards, on which wind turbines are hung, and with a bearing at the top, a bearing connected with a cable stretched between two masts, a pair of sails mounted on y-rails in the form of semi-cylinders, receiving a couple of forces from the wind, forcing a flexible shaft to rotate, relaying a friend no other offset by an angle of 90 o, wherein both the cable of the flexible shaft are fixed in recesses - four holes, through which passes the rope and made consistent rise yards up the ropes of the flexible shaft and the other end of the halyard spreads through the stationary block - roller for segment thick the wires tie the end of the file, missed through four holes, after successively raising all wind-driven engines along the shaft cables, the end of the file is sealed behind a clip fixed to the shaft cables in its lower part, but with complete weakening the end of the tether, the sails will develop on a platform above the electric generator, the flexible shaft will stop, but the generator can be stopped and clutch mounted on the generator.
