INVENTION
Russian Federation Patent RU2043536
Windmills
Name of the inventor: Rakovsky Vladimir Fedorovich
The name of the patentee: Rakovsky Vladimir Fedorovich
Address for correspondence:
Starting date of the patent: 1990.05.07
Use: in the wind industry. The inventive wind power plant includes a blade portion 12 mounted in a bearing assembly, mounted on the vertical support structure, an electric generator 15 mechanically connected with the blade portion 12 through the power shaft 13, a concentration-guide elements mounted on a foundation. Paddle portion is provided with confuser 11. The concentration-guide elements are spiral ring with evenly spaced vertical slits. By the ring zone in the slits vertically adjacent panels are flat screens, which are mounted in a plane coinciding with the tangent to the circumference of the ring and are held by means of slopes and stretch marks.
DESCRIPTION OF THE INVENTION
The invention relates to wind energy.
Known wind power plant comprising a blade portion mechanically connected with the blade part of the generator, a guiding device.
The invention aims to improve the efficiency and increase the strength of installation structure.
This goal is achieved by the fact that wind power plant consists of a blade portion mechanically associated electrical generator, the support structure, the devices for the conversion and storage of energy wind, further comprising mounted on a foundation of vortex generating concentration-guide elements, and the wind turbine axis is set vertically and coincides with the central axis of the vortex upstream.
Concentration-guiding elements are cylindrical ring with six evenly spaced vertical slits (air gaps) and six vertically adjacent to the ring in the zone of the slits flat aerodynamic screens shields, the shields are mounted in a plane coinciding with the tangent to the circumference of the ring and the slot is in top shape (angle) formed by the shield and ring.
Blade portion is mounted in the bearing assembly secured to a vertical supporting structure (pole) is provided with a confusor flux concentrating element, and a generator mounted on a bottom surface connected in a vertical direction extended shaft power.
Paddle part is made by the type-mnogorotornoy coaxially with variable diameter of each subsequent rotor congruent profile of the diffuser element.

1 shows a wind power plant, a side view; Figure 2 is the same as the top view.
The wind power plant consists of a ground 1 and 2 aboveground parts. 1 comprises a ground part 3 spiral ring with six slits 4, slots for passage of the airflow. By the ring 3 in the slots area adjacent six wind screen 5. Screen 5 is designed as a thin-walled flat panel in the form of elongated parallelogram. Each screen 5 is oriented tangentially to the circumference of the ring 3 so that the slit 4 located at the apex of the angle shape formed by the horizontal axis of the screen and forming a ring. The upper edge of each screen 5 is provided with a visor 6 mounted at an angle of about 90 (or slightly less) of the screen. Canopy is focused to form a ring. The screen is fixed upright and slopes extensions 7. The cylindrical ring 3 assembled from several (six in this case six or a multiple of) elements. Each element describes part of a circle, fixing all the elements provided by the upper 8 and lower 9 metal shrouds.
Aboveground part 2 comprises a tripod mast-10, to the top of which is attached inside the convergent element 11. confuser element 11, along the vertical axis is set to the operational gap mnogorotorny blade unit (blade portion) 12. The axis of the blade is vertical. Power shaft 13 connects with a blade portion 12 mounted on the base part 14 of the electrical generator 15. Base plates 14, laid down under the ring 3, not have a flat configuration, and are contoured (stacked) so as to form a conical surface mild. The top of the cone rises above the periphery of the forming ring 3. The cone angle of 120-160. The generator 15 is mounted on the top of the cone (truncated cone) and closes the casing 16 and having a conical shape. Generator Version 15 model. The mast-mounted tripod 10 of the three farms, each "leg" which is strengthened on the base plate outside the ring, or when sufficient rigidity (see FIG. 1, 2) strengthened directly on the upper shroud ring 8 3. In all versions mast 10 is stabilized mechanical rope stretch marks. The slots in the ring 3 in some cases (especially large plants) can be equipped with controlled (open-closed) shutters, blinds (not shown).
The electrical part of the generator 15 is connected to the device 17 vetrovodorodnogo storage.
Wind Turbine operates as follows. The wind flow gets into fragments of the plane formed by the screen 5. With further movement of air masses partly by changing its direction of motion, rush to the ring 3, increasing the concentration of the path of the energy flow, the flow rate increases. This effectively works half the screen, ie, three fragments. Visor Screen 6 5 Leakage reduces the flow in the vertical direction, optimizes the flow. The concentrated flow-through slit is then slit 4 is supplied with a high speed into the ring 3. The speed vector oriented screen 5 tangentially to a circle inside the ring so linear flow changes to rotational. Due to the conically profiled surface of the foundation 14 of the (lower) flow is involved in an upward movement up vertically. The stimulatory effect of air vortex. An additional effect is produced by a helical (spiral) of the ring profile, favoring the maximum concentration of energy vortex in the center of the ring. Up from the central portion along a vertical axis lying artificial vortex in confused further element 11 is stabilized it is achieved an even higher degree of concentration, and is sent to the paddle portion 12. The interval between the top ring 3 and the lower edge of the diffuser element 11 in the dynamic structure of the artificial intense vortex involved the surrounding air layers and increase its energy potential. The energy of rotation of the blade 12 further power is transferred to the generator shaft 15, according to the classical scheme is transformed and transmitted to the consumer and vetrovodorodnoe accumulating unit 17.
