Use: in the electric power industry, in particular in the design of wind power plants. SUMMARY OF THE INVENTION: the use of several vortex generators located at certain distances along the height of the pipe, in the slots of each of which the air flow enters through the sockets of the guide devices that capture the entire airflow along their height and width from the direction of the wind, will create a powerful vortex air Flow, in the range of which the wings of the wind-wheels are placed on the vertical shaft at the optimal angle. In addition, during the operation of the vortex generators, each of them creates a vacuum, resulting in additional air portions being sucked both from the direction of the wind and through the open side slits and openings in the lower part of the tube, which will increase the power of the vortex airflow.

DESCRIPTION OF THE INVENTION

The invention relates to the electrical and electric power industry, in particular to the design of wind power plants.

In known wind-driven installations mounted in a pipe, an upward air flow (upstream) is used, and, as a rule, these installations are based on traditional cylindrical generators.

A vortex electrical installation is adopted for the prototype (as N 1021804, F 03 D 3/04, published in 1983).

The essence of the proposed invention is that when an impact on the wind wheels (VC) is not using an ascending airflow (upstream), but a vortex air current (vvp) directly in the pipe created by Generator of the vortex (g.v.). On the wings of each wind wheel (VK) works its own g.v.

The vortex air flow formed by the city of. Is located at some distance from the central axis (shaft) and from the inner surface of the pipe (an approximate arrangement of the EH zones in the pipe is shown in FIG. 2). Thus speed in. Gt; (Zone I) increases several times (by a factor of 5 7) compared with the speed of the wind at the entrance to the pipe and reaches a maximum in the core of the high-voltage column. (Zone IV). Velocity speed In the central part of the tube (zone II) is close to zero, and at its inner surface (zone III) is approximately equal to the velocity at the entrance to the pipe. With different tube diameters, the position of the VD will be different. As the diameter of the pipe increases, the speed of the alternating current increases. In comparison with the speed of the wax. Gt; The inner zone (zone II) will increase by the same amount. The total area of ​​the river will decrease. Gt; Consequently, the resulting power of the wind turbine as in the case of re.v.p. So and with vv.p. Will be the same; The law of conservation of energy is not violated. But the whole point is that when using the vv. Which, squeezed, is located in a favorable location for the selection of wind energy pipe, its speed is several times higher than the speed of the vv.p.

Climbing up the spiral, in. at. Etc. with the same effort constantly affects the wings. Which are set in vv.p. (Zone I) at the optimum angle. In the inner part of the pipe (zone II), where the speed of the HP is high. Is close to zero, there is a shaft with fixation elements and fastening elements in. K. P or counterweights for single-winged v. In addition, because of the small lever, the use of wax. at. Etc. in the inner zone would be ineffective. V.p. The outer zone (zone III) is also not used, therefore, there is no need to grind the inner surface of the pipe when taking into account friction losses.

Considering the fact that when interacting with an av. With wings It will be partially destroyed, it is supposed to form a high-voltage column at the height of the pipe. And the opening and closing of the slits of the city. Produces automatic shutters. In addition, the guiding apparatuses, connected to the pipe and the metal frame, reinforce (hold the pipe, whose mechanical strength is lowered at the places of the slots of the hv and the lower holes.

When working, each of the cities. Creates a vacuum under itself, which means that the speed is increasing. at. Etc., therefore, the missing amount of air will be sucked through the lower openings and slots of the g. Which will increase the power of the VD.

The technical solution is illustrated by the drawings, where it is shown: in FIG. 1, a VENA without guide devices in a section. The disk generator is placed in the foundation on which the pipe rests. The generator shaft is moved to the maximum (maximum possible) height. On the shaft, which is fixed through the bearings by the profile plates, several VCs are fixed. With wing devices. The height of the pipe shows the slits of four years. In the lower part of the tube additional holes are shown, and in the upper deflector; FIG. 2 shows a pipe in cross-section with an exemplary arrangement of distribution zones, Where the advantage of putting the wind wing in the area of ​​the east-west is evident. (Zone I) at the optimum angle; Fig. 3 shows a part of a pipe from a h. Where slits and automatic latches are visible; 4 shows a general view of the VENA, whose pipe is mounted on the foundation. In the upper part there is a deflector, and in the lower part - additional openings. The walls of the funnels of the four sections of the guide devices on the inner side are attached to the pipe at the places of the slots of the g. And from the outer to the metal frame resting on the foundation; 5 shows part of a pipe with lateral guides; FIG. 6 shows a pipe with lateral guiding walls in a cross-section, where it is clearly visible how much grip the HP increases.

VENA consists of: pipe 1 with a. 8, of the disk generator 14 (other types of generators can be used) with a shaft 3, which are fixed in. 2 and the fastening elements of the shaft 9, the additional holes 12, the automatic shutters 5, the guiding apparatus with the side 15, the upper and lower 7 walls of the bell 7, the metal frame 6, the foundation 11. The arrows 10 show the direction of the wind.

A metal pipe is 20 times lighter than a detailed reinforced concrete structure.

In VENA, instead of the traditional cylindrical generator, it is advisable to use a powerful low-speed disk (carrousel) generator located horizontally. The vertical shaft of the generator, on which several are fastened. To. It is deduced on the greatest possible height and without transitive devices (reducers) it is connected with a disk-rotor. The angular rotation speed of the shaft is from 10 to 50 rpm. The disc-rotor will simultaneously act as a powerful flywheel. It is possible to use other types of generators.

The winding comes from the direction of the wind in the pipe through the sockets located along the entire height of the guiding apparatuses. Thanks to the lateral guiding walls of 15 v. Acquires vortex motion. Vortex s.p. Occupying a certain position in the pipe (for different pipe diameters it will be different), interacting at the optimum angle with the wings. 2, rotates the shaft 3 of the generator 14. At the same time, the lower vortex generator (g) acts on the windscreens of the first windscreen (VC) and, creating a depression under itself, sucks in additional air through the additional holes 12, the second and third r .at. Working on their own. Simultaneously restore the partially destroyed in. Gt; On the previous wind wheels (VC). The last vortex generator supports the vortex motion v. Due to the depletion created by all the g.v. The speed of the high-speed current increases. And the missing amount of air will be sucked through additional openings at the base of the pipe and the slots of the h. Which increases the power of voltages.

Number of years in. And v.k. Will depend on the length of the shaft of the generator, the permissible distance between the VCs. And on the effort necessary to rotate a particular rotor of the generator, and the number of wings Their shape and dimensions should be chosen in such a way that the c.v. After partial destruction, at the approach to the next vk Restored.

Speed ​​in. Gt; Will be constant, because Sudden changes in wind speed will be smoothed by a powerful flywheel, the role of which is performed by the rotor of the generator, and the arrival of the alternator. In a pipe with long changes in wind speed will be controlled by automatic flaps.

The proposed vortex installation does not require orientation relative to the direction of the wind.

VIENNA is completely harmless in an ecological sense, it occupies a small area for its construction. Moreover, if modern powerful wind turbines, using wings of a large area, interfere with local TV-radio reception, then electromagnetic oscillations created by friction About the wings Will be shielded by a metal pipe.
