Russian Federation Patent RU2008516
WIND ENERGY CONVERTER
Name of the inventor: Lisowski Nikolai Vsevolodovich

Starting date of the patent: 1991.05.20
Use: wind power. The inventive vetrovosprinimayuschy wind energy converter element is a confusor space formed by two hollow spherical segments with a common central axis running through the vertices of ball segments convexities facing each other. The internal cavity of spherical segments are reported by channels - rack, fastening past each other.
DESCRIPTION OF THE INVENTION
The invention relates to the field of wind energy, in particular energoprivodnym devices, for example for lifting water can be used in industrial plants and other local power supply.
Known wind energy converters with perceiving type aerodynamic elements, which provide operational direction of the air flow required for more efficient operation of Secondary converters wind flow and mechanical energy and electric turbines, located in the working air stream.
In these converters aerodynamic elements are convex curved surfaces in contact with the oncoming wind stream. contact region informs channel system (holes, nozzles, slots) to the area in which the turbine is located. Due to underpressure created in this area there is air leak through a system of canals that forms a working air flow constant direction. This flow and activates a turbine (or other actuating means).
At low wind speeds the vacuum value in the contact area is small, which greatly affects the energy capabilities of the workflow.
Low efficiency at low wind speeds is the main disadvantage of said technical solutions.
The closest to the proposed converter is, where aerodynamic vetrovosprinimayuschy element is an ejector tube, oriented on the wind direction and mounted on the upper end of the riser pipe at the bottom of which has a main inlet.
The wind flow through the ejector pipe, draws the working air stream, accelerating its movement along the vertical pipe into which it enters through the top hole. Accelerated air flow constant direction propeller provides favorable conditions of work, using the kinetic energy of the stream.
The disadvantage of this solution is the complexity of the design, the necessity to orient vetrovosprinimayuschy element according to the wind direction and low efficiency, especially in light winds.
The aim of the invention is to simplify the design and increase efficiency vetropreobrazovatelya.
This goal is achieved by the fact that the aerodynamic vetrovosprinimayuschy element is a spatial convergent channel formed by two hollow spherical segments with a common central axis passing through the tops of bumps, facing each other, and the inner cavity of spherical segments are reported by channels, counters, fasteners past each other .
The proposed constructive solution eliminates the need to orient vetrovosprinimayuschy element according to wind direction and wind accelerates the incoming flow at the point of restriction between the tops of spherical segments and a corresponding increase in vacuum at the contact surface element, which accelerates the flow of working air.
General view of a wind energy converter is shown in the drawing.

Vetrovosprinimayuschy element consists of a top spherical segment 1, the bottom spherical segment 2 which include bottom 3, curved working surface 4 with the airfoil suction holes 5 and 6 the internal cavity communicating between a channel-pillars 7. The channels 7-bonded ball rack segments 1 and 2 together into a single whole-spatial konfuzor. At the bottom of the lower segment 2 has a hole 8, stating the cavity 6 with the working channel 9, combined with the support 10. The lower segment is connected to the support 10 and fastened cable-stayed stretch marks 11 placed around its periphery. |
WORKS CONVERTER AS FOLLOWS
The incoming wind stream moving with speed V, getting into the space between the segments 1 and 2, it is accelerated due to the narrowing of the local curvature and aerodynamic surfaces and contact 4 reaches V max speed. On the surfaces 4 in accordance with the laws of aerodynamics arises vacuum, in which through holes 5 sucked air out of the internal cavities 6 segments 1 and 2, and through the channels, the rack 7 and opening 8 and from the working channel 9, which creates an air flow in a constant direction.
Compared with the prototype proposed wind energy converter provides a higher degree of vacuum at low wind speeds, higher efficiency with a simple and robust design.
