INVENTION
Patent of the Russian Federation RU2114317
WIND POWER STATION SAIL-2 (VEGG-2)
The name of the inventor: Georgy Vladimirovich Ginkulov
The name of the patent holder: Ginkulov Georgy Vladimirovich

Date of commencement of the patent: 1995.07.21
VEHG-2 is a wind power station sailing, it can be manufactured for the rotation of generators of low power (ie, with only one wind turbine on a vertical shaft) and for the rotation of high-power generators-with several propellers on the shaft. Suspended windmills, vertically fixed on one shaft, rotate the slow-moving generator, which is on the ground. Supports for the suspension of propellers are two masts, between which the cable is pulled. The bearing is fastened on this cable in a plate clamp. The bearing is connected to a flexible shaft. On this shaft are attached all propellers. The flexible shaft consists of four cables, between which two steel thin bars perpendicular to each other and to the flexible shaft are passed, but so that a cross with equal shoulders is formed. Sails hang on these shoulders. To the lower corners of each sail are tied the leashes. The ends of these two leashes at each sail are passed through the gold rings. The ring is held by stretch marks at the middle of the distance between the ends of the rods of the main spider. It is this that keeps the sail in the vertical position when the working stroke is made. It is through the golden ring that the cord is pulled to stop the rotation of the propeller. One end of this cord is connected to the middle of the lower edge of the sail, and the other end of the cord is connected to the lower small cross. When pulling all four cords - all four sails will be placed horizontally and the propeller stops. The technical result consists in increasing the efficiency of the wind farm, simplifying the design.
DESCRIPTION OF THE INVENTION
The invention relates to wind power, in particular to wind power plants.
A wind power plant is known, containing a slow-moving electric generator, rotated by four-wind turbines mounted on one flexible shaft [1].
The purpose of the invention is to increase the efficiency of the wind farm, reduce operating costs by simplifying the design and installation, and by reducing the number of units involved in the scheme.
The goal is achieved by the fact that due to the free vertical suspension of the sails on the rivers, they, inflated by the wind, communicate the torque to the mast, i.e. The flexible shaft that transmits this rotation to the generator.

VEHG-2 can consist of one or more sailing propulsors rotating a low-speed electric generator. All propellers VEPG-2 are mounted on a suspension flexible shaft 1, which consists of four cables. The shaft 1 is attached to the bearing, and the bearing to the horizontal cable, which is tensioned between the two masts. Each propeller consists of two thin steel rods 2 and four sails 3. The rods 2 are passed between the ropes of shaft 1 forming a cross. In the middle of each rod 2 are welded two pieces of iron wire 6-8 mm long, perpendicular to each other to the rod 2. With this design of the rods 2, they will be securely fixed to the shaft 1, since all four shaft cables 1 are compressed by double-skew clamps 5. One Clamp 5 is located above the cross, the other - under the crosspiece. The horizontal position of the rods 2 is controlled by four phal rods 6. Some ends of the couplers 6 are attached top to the four rings 7 on the small cross 8 and the other ends of the couplers 6 to the rings 9. All the rings 9 are pulled into the holes of the four power washers 10. The washers 10 are fixed to Ends of rods 2 cotter pins or threaded connection. Each sail 3 is hung on the rod 2 as the window curtain is hung on the thread. The other three edges of the sail 3 must be sewn thin polyethylene (or duralumin) tubules. This will give rigidity to the sails 3. On the rods 2, all sails 3 are between small washers 11.
The work of the VEP is carried out as follows
Let the wind blow from the south (S) to the North (N), then at the moment the left sail will perform the working stroke, and all the other three sails 3 will be prepared for it. And already, when the shaft 1 is rotated by 10-15 o, the next sail 3 begins to move. The continuous operation of the sails 3 is due to the fact that each sail 3 is held in the wind in an upright position with the help of length-adjustable two leashes 12 sewn to The lower corners of the sail 3. The ends of the leashes 12 are attached to the gold ring 13. All four gold rings 13 are placed in the middle between two adjacent washers 10 on the stretches 15. So, each of the eight stretch marks 15 is fixed at one end to the gold ring 13, and the other end to Washer 10. The washer 10 has four holes at equal distances. To stop the rotation of the propeller, a cord 16 is provided. It is attached to the middle of the lower edge of the sail 3. Next, the cord 16 is passed through the gold ring 13, then through one of the four rings on the upper minor cross and from it to the lower minor cross, on which the second End of the cord 16. The propeller has four sails 3, and hence four cords 16. If two propulsors are located on the shaft 1, then four more cords 16 will be attached on the small lower cross 16. When all the cords 16 are tensioned, all sails 3 will take a horizontal position and Shaft 1 will stop.
CLAIM
A wind power plant (VEPG-2), comprising a slow-moving electric generator, rotated by four-wind wind turbines mounted on one flexible shaft, characterized in that the flexible shaft consisting of four cables connected to the bearing is fixed to a horizontal cable stretched between two masts, each The windmill consists of a cross made of two steel rods and four sails, these rods being passed between the shaft cables forming a cross, two pieces of iron wire are welded in the middle of each rod so that they are perpendicular to each other and to the shaft itself, the flexible shaft is compressed by clamps - one above the rod and the other under it, the sails are fixed to the cross, each sail is held in the wind in a vertical position with the help of length adjustable two leashes, the ends of the leashes are tied to the ring, all four rings are placed in the middle between two adjacent washers on the stretchers, for Stopping the rotation of the propeller is provided a cord tied to the lower edge of the sail, the cord through the ring is passed through one of the four rings on the upper small cross, with the tension of all the cords, all sails will occupy a horizontal position and the shaft will stop.
