Description
"DISPOSITIVO PER IL CONVOGLIAMENTO, SU ROTORI EOLICI INTERNI, DI MASSE AERIFORMI"; "DEVICE FOR CONVEYING AERIFORM MASSES ON INTERNAL WIND ROTORS";
TESTO DELLA DESCRIZIONE TEXT OF THE DESCRIPTION
L'invenzione concerne un dispositivo per il convogliamento, su rotori eolici interni, di masse aeriformi, atto ad aumentarne il rendimento energetico. The invention relates to a device for conveying gaseous masses on internal wind rotors, capable of increasing their energy efficiency.
E' noto che i generatori elettrici, o di altro tipo, alimentati dalla energia eolica, sono limitati dalla estensione presentata dalla superficie delle pale o eliche rotanti, rispetto alla massa delle molecole dell'aeriforme, utile per gli impatti. Di conseguenza, per sfruttare la pressione del vento su generatori di potenza e rendimento rilevanti, si mostra negativo ingrandire la superficie e/o la estensione delle pale o eliche, con ingombri e costi elevati. It is known that electric or other generators powered by wind energy are limited by the extension presented by the surface of the rotating blades or propellers, with respect to the mass of the aeriform molecules, useful for impacts. Consequently, to exploit the wind pressure on significant power and efficiency generators, it is negative to enlarge the surface and / or the extension of the blades or propellers, with high overall dimensions and costs.
Scopo della presente invenzione è quello di raccogliere e convogliare una massa di aeriforme superiore alla superficie geometrica delle pale dei rotori eolici, aumentandone il rendimento. The purpose of the present invention is to collect and convey a mass of gaseous material greater than the geometric surface of the blades of the wind rotors, thus increasing their efficiency.
Lo scopo si raggiunse con il dispositivo, secondo l'invenzione, costituito da una struttura fissa, e cioè non rotante sotto l'azione del vento, composta da moduli asserablabili all'intorno dell'asse del rotore eolico, ognuno costituito da più diaframmi disposti radialmente in modo tale da convogliare sulle pale del rotore centrale tutta la massa aeriforme corrispondente allo steradiante individuato dalla superficie esterna di imbocco, lungo una direzione inclinata nel verso di rotazione della turbina, senza l'incidenza sulla sua parte negativa. The purpose was achieved with the device, according to the invention, consisting of a fixed structure, i.e. not rotating under the action of the wind, composed of modules that can be asserted around the axis of the wind rotor, each consisting of several diaphragms arranged radially in such a way as to convey on the blades of the central rotor all the gaseous mass corresponding to the steradian identified by the external inlet surface, along an inclined direction in the direction of rotation of the turbine, without affecting its negative part.
I vantaggi dell'invenzione sono numerosi ed evidenti: - aumento del rendimento del rotore eolico centrale, conseguente all'aumento della massa di aeriforme convogliato; - possibilità di progettazioni dimensionali diverse, secondo le esigenze, da strutture a pennone alte e strette a conformazioni cilindriche di grande diametro, per grandi potenze; The advantages of the invention are numerous and evident: - increase in the efficiency of the central wind rotor, consequent to the increase in the mass of conveyed aeriform; - possibility of different dimensional designs, according to the needs, from tall and narrow flagpole structures to large diameter cylindrical conformations, for large powers;
- sicurezza operativa, derivata dalla protezione delle pale del rotore centrale, da parte del dispositivo fisso, che lo comprende; - operational safety, derived from the protection of the central rotor blades by the fixed device, which includes it;
- possibilità di preferibile disposizione dell'invenzione in verticale per la semplicità dei collegamenti alle apparecchiature elettriche ma anche possibilità di utilizzazione con asse orizzontale o diverso; - possibility of preferably arranging the invention vertically due to the simplicity of the connections to the electrical equipment but also the possibility of using it with a horizontal or different axis;
- Componibilità di più moduli,per l'aumento del rendimento L'invenzione è esposta più in dettaglio nel seguito con l’ aiuto dei disegni che ne rappresentano alcuni esempi di esecuzione. - Modularity of several modules, to increase the yield The invention is set out in more detail below with the help of the drawings that represent some examples of execution.
La fig. 1 rappresenta, in schematizzazione in pianta, un dispositivo per il con voglia mento, su rotori eolici interni, di masse aeriformi. Fig. 1 shows a schematic plan view of a device for conveying gaseous masses on internal wind rotors.
La fig. 2 rappresenta, in vista assonometrica, un dispositivo a due strati sovrapposti di diaframmi radiali. Fig. 2 shows, in axonometric view, a device with two superimposed layers of radial diaphragms.
La fig. 3 rappresenta una variante a più strati sviluppati in altezza. Fig. 3 represents a variant with several layers developed in height.
Le figure rappresentano un dispositivo per il convogliamento di grandi masse di aeriforme sulle pale di rotori, disposti all'interno del dispositivo stesso, comprendente: - più strati sovrapposti di diaframmi fissi 1 , disposti in posizione radiale rispetto alla superficie cilindrica 2 del rotore eolico centrale a palette 3, in modo tale da convogliare le masse aeriformi corrispondenti allo steradiante di imbocco 4, direttamente negli spazi 5, di piccolo volume, esistenti tra dette palette 3, nel verso positivo di spinta, senza incidenza sulla parte negativa; The figures represent a device for conveying large masses of aeriform on the rotor blades, arranged inside the device itself, comprising: - several superimposed layers of fixed diaphragms 1, arranged in a radial position with respect to the cylindrical surface 2 of the central wind rotor vane 3, in such a way as to convey the gaseous masses corresponding to the inlet steradian 4, directly into the spaces 5, of small volume, existing between said vanes 3, in the positive thrust direction, without affecting the negative part;
- Più dischi 6 sovrapposti in successione, atti alla delimitazione degli spazi tra detti diaframmi ortogonali 1 , con individuazione degli steradianti di imbocco 4, e al fissaggio in 7 dei diaframmi stessi; - Several disks 6 superimposed in succession, suitable for delimiting the spaces between said orthogonal diaphragms 1, with identification of the inlet steradians 4, and for fixing the diaphragms themselves in 7;
- un rotore eolico a palette 3, o di altra conformazione, disposto in posizione centrale lungo l' asse A , interno alla struttura a strati 1 ; - a wind turbine rotor with blades 3, or of other conformation, arranged in a central position along the axis A, inside the layered structure 1;
- mezzi di sfruttamento dell' energia di rotazione derivata dalla energia eolica. - means of exploiting the rotational energy derived from wind energy.
Secondo l' invenzione, detti diaframmi 1 , oltre che piani e fissi, come descritto, possono essere realizzati, in possibili varianti, a struttura curva per facilitare lo scorrimento delle molecole aeriformi verso il rotore, e ad angoli regolabili, in funzione all'intensità e della qualità del vento. According to the invention, said diaphragms 1, in addition to being flat and fixed, as described, can be made, in possible variants, with a curved structure to facilitate the sliding of the gaseous molecules towards the rotor, and at adjustable angles, according to the intensity. and the quality of the wind.
Inoltre, in ulteriore variante, è prevista anche una possibile estensione superficiale dei diaframmi con l' estroflessione, manuale o automatica, dei terminali, per l' aumento della massa aeriforme convogliata. In addition, in a further variant, a possible surface extension of the diaphragms is also provided with the manual or automatic extension, either manually or automatically, of the terminals, for the increase of the conveyed gaseous mass.
Naturalmente fermo restando il principio del trovato, le forme di realizzazione e i particolari di costruzione potranno essere ampiamente variati rispetto a quanto descritto e illustrato, senza per questo uscire dall' ambito della presente invenzione. Naturally, the principle of the invention remaining the same, the embodiments and construction details may be varied widely with respect to those described and illustrated, without thereby departing from the scope of the present invention.
