Abstract

The device according to the present invention consists of a fixed structure, i.e. not rotating under the action of the wind, consisting of modules that can be assembled around the axis of the eolian rotor, each one consisting of a plurality of diaphragms (1) radially placed so as to lead all the aeriform mass, corresponding to the steradian (4) determined by the external entrance surface, onto the blades (3) of the central rotor along an inclined direction in the rotation direction of the turbine, without incidence onto the negative part.

Description

VERTICAL AXIS WINDTURBINE WITH AUGMENTING VANES
The present invention concerns a device for the conveyance of aeriform masses onto internal eolian rotors, for increasing the energetic output thereof .
It is known that the electric generators , or of other kind, fed by eolian energy are limited by the extension of the rotating blades or propellers, with respect to the mass of the aeriform ' s molecules , usef ul for the impacts . Consequently, it has shown to be negative to increase the surface and/or the extension of the blades or propellers , with increased encumbrance and costs, for exploiting the pressure of the wind onto considerable power and output generators .
It is the aim of the present invention to gather and lead the mass of aeriform greater than the geometric surf ace of the eolian rotors ' blades , t h u s increasing the output thereof .
The aim set forth is reached by means of the device according to the present invention, consisting of a f ixed structure , i . e . not rotating under the action of the wind, consisting of modules that can be assembled around the axis of the eolian rotor , each one consisting of a plurality of diaphragms radially placed so as to lead all the aerif orm mas s , corresponding to the steradian determined by the external entrance surface , onto the blades of the central rotor along an inclined direction in the rotation direction of the turbine , without incidence onto the negative part .
The advantages of the device according to the present invention are many and considerable :
- increase of the output of the central eolian rotor , following to the increase of the mass of led aeriform;
- possibility of different dimensional planning , according to the requests , from high and narrow pennon structures to cylindric shapes with great diameter , for great powers;
- operative safety deriving from the protection of the central rotor ' s blades by the f ix device comprising it;
- possibility of preferably placing the device according to the present invention in vertic al position for the semplicity of the connections to the electric apparatuses , but also possibility of use with horizontal or different axis; - the possibility of being composed of a plurality of modules for increasing the output.
The present invention will be described more in detail hereinbelow with reference to the enclosed drawings in which some embodiments are shown.
Figure 1 shows a plant scheme of a device for the conveyance of aeriform masses onto internal eolian rotors.
Figure 2 shows an axonometric view of a device with two superimposed layers of radial diaphragms.
Figure 3 shows a variant with a plurality of layers, develloped in height.
The enclosed figures show a device for the conveyance of great aeriform masses onto rotors' blades placed inside said device, comprising:
- a plurality of superimposed, fixed diaphragm layers 1, placed in radial position with respect to the cylindrical surface 2 of the central eolian blade rotor 3, so as to lead the corresponding aeriform masses to the entrance steradian 4, directly in small spaces 5 between said small blades 3, in the positive push direction, without impact on the negative part;
- a plurality of discs 6 superimposed in succession, for the limitation of the spaces between said orthogonal diaphragms 1, with determination of the entrance steradians 4, and for the blocking in 7 of said diaphragms;
- an eolian rotor 3 with blades or of any other shape, placed in a central position along axis A, internal to the layer structure 1;
- means for exploiting the rotation energy deriving from the eolic energy.
According to the present invention, said diaphragms 1 may be realized, as above described, as flat and fixed, but also in possible variants with a curved structure for facilitating the sliding of the aeriform molecules towards the rotor, and with angles adjustable according to the intensity and the quality of the wind.
Furthermore, in a further variant a possible extension of the diapragms' surface is provided with the manual or automatic projection of the end parts for increasing the aeriform mass conveyed.
