Patent of the Russian Federation RU2115018
WIND SAIL PLANT "VEPG"
The name of the inventor: Ginkulov George Vladimirovich
Patentee name: Ginkulov George Vladimirovich
Starting date of the patent: 1995.07.21
VEPG can be mounted from one or several wind turbines. Each VEPG propulsion unit is mounted from separate parts (sails, rods, halyards) directly on a suspension consisting of four cables forming a power flexible shaft connected to a bearing. And this bearing with the help of a clamp mounted on a horizontal cable, which is stretched between two or three high masts. The wind turbine itself is assembled by introducing between four cables of a flexible shaft two strong rods perpendicular to each other and to a flexible shaft. These two rods, fixing the clamps on the flexible shaft, form one crosspiece, and lower, to the height of the sail, similarly mount the second crossbar. And between these two crosses (on their shoulders) they hang four sails, since there are only four pairs of shoulders - four sails. But the sails are hung in such a way that the moment of one of the four sails acts on the flexible shaft all the time, transferring this rotation to the generator installed below. This is due to the fact that the vertical edge of the sail, which is further away from the center, is like a hinge, relative to which the entire sail can make oscillatory movements, and the other vertical edge is attached to the leads. The free ends of these leashes are attached to the vertical outer edge of the adjacent sail. The width of the sail and the length of its leads must have slack, but such that the efficiency of the working stroke is maximum. With such a chosen slack of leashes, that sail, which is opened by the wind, makes a working turn, and the three other sails “prepare” for this turn. The technical result is to increase the efficiency of wind turbines, simplify the design, reduce operating costs for installation and construction.
DESCRIPTION OF THE INVENTION
The invention relates to the field of wind energy, in particular to sailing wind turbines, which can be installed on ships and on land and can be used in areas dominated by strong winds and there is a shortage of electrical energy.
Known wind power installation, containing each wind turbine four sails, which are working blades.
The purpose of the invention is to increase the efficiency of wind turbines, simplifying the design, reducing operating costs for installation and construction.
This goal is achieved by the fact that the movers VEPG are sails mounted on a flexible shaft, which rotates on the suspension.
FIG. 1 shows only one four-level propulsion VEPG, side view; in fig. 2 is a top view of this propulsor in its working moment; in fig. 3 - external view of low-power VEPG.
Wind turbines (HP) of sailing type are used to rotate the generator on VEPG. They can be several, united in one garland, which is fixed on the horizontal cable 1 by means of a clip 2 consisting of the upper bar 3 and the lower U-shaped bar 4 in which the bearing 5 is fixed. The bars 3 and 4 are fixed on the cable 1 with four bolts 6 (there are only two in Fig. 1). Four force rings 7 are connected with the bearing 5, FIG. 1, only two rings 7 are visible. Through two of them two cables 8 are stretched, the length of which must be such that after they are pulled into these rings 8, they must reach the ends of the generator to the generator installed on the ground. So, the resulting flexible shaft 9 consists of four cables, the shaft of the generator and is in a vertical position. Four sails 10 are suspended between two crosses 11. Each crosspiece 11 consists of two rods 12, and two short lengths of wire perpendicular to each other are welded on the middle of each rod 12, forming a small cross 13 that keeps the rod 12 from moving along its axis. And each crosspiece 13 is held from displacement along the axis of the flexible shaft 9 by special two arcuate clips 14, one clip from the top of the crosspiece 13, and the other from the bottom. So, each propulsion unit consists of two crosses 13 and four sails, stretched between them. Depending on the power VEPG on the flexible shaft can be mounted several thrusters, forming a garland of thrusters. The power of VEPG can be increased by the number of these chains, and hence the number of generators. For VEPG low-speed generators are used.
WORK OF VEPG IS FOLLOWED AS FOLLOWS
FIG. 1 and 2, it can be seen that at this moment of time rotation of the flexible shaft 9 is communicated only by the left sail, and the remaining three sails do not give rotation, but almost do not hinder this rotation, since at this moment they turn downwind. This is achieved due to the fact that all external vertical edges of all four sails are tied to jumpers 17 by knots 16. These nodes 16 are like hinges for the “doors” - sails 10, and the halyard wires 18 turn these “doors” of the rail-10 so that In full force, one of the sails worked, and the other three consistently prepared for this work using the wind. From FIG. 1 and 2 you can see that one ends of the leads 18 are attached to the sails 10, and their other ends to the jumper 17, but on the other adjacent shoulder of the same cross 11. The length of the leads 18 must be strictly defined, otherwise the sail stroke will have low efficiency. In case of large-sized VD, the ends of their crosses 11 should be connected with horizontal file-shaped stretch marks 19, tying them to the ends 20, which are located at the ends of these crosses 11. In FIG. 2 of these extensions 19 are shown in dashed lines. The horizontal position of the shoulders of all crosses 11 is regulated by four folovye stretch marks 21.
The constructive view of stopping the rotation of the entire mote garland looks very simple. Using the tension of the harnesses 22, all the jumpers 17 are assembled towards the center, pressing the sails against the flexible shaft 9, and with the help of the tension of the harnesses 23 all the jumpers 17 move from the center, revealing all the sails of the string. The ends of the harnesses 22 and 23 are attached at the bottom to the small cross 24, which has the same construction as the cross 11. Each harness 22 and 23 consists of several laces. Each string controls only one sail, since all the upper ends of these laces are tied to the upper rings 25 of each sail, and when the rope is strained 22 or 23, these rings 25 will slide over the arms of the cross 11, folding or opening the sails.
A wind sailing power station device containing four sails for each wind turbine, which are working blades, characterized in that the working blades are suspended between two crosses, leashes are attached to the sails at one end, and the other end is attached to the jumper on the other adjacent cross arm, flexible shaft, transmitting the rotation from the wind turbines to the electric generator, assembled into a bundle of four cables, and the crosses on which the sails are suspended are made of two rods and fixed with clamps on this lu, thrusters are formed in the garland capable of rotating low-speed generator.
