Description

DESCRIZIONE TECNICA TECHNICAL DESCRIPTION

Il campo di applicazione di questa nuova idea è il settore delle energie alternative rinnovabili, unisce i due sistemi di conversione, da fonte solare ed eolica in un’insieme perfettamente integrato. L’energia solare è convertita in energia elettrica a corrente continua da una cella fotovoltaica a concentrazione irraggiata con dispositivi ottici a specchi parabolici o con lenti di Fresnel. The field of application of this new idea is the alternative renewable energy sector, it combines the two conversion systems, from solar and wind sources in a perfectly integrated whole. Solar energy is converted into direct current electricity by a photovoltaic cell with irradiated concentration with optical devices with parabolic mirrors or with Fresnel lenses.

Gli apparati ottici si integrano nello statore di un alternatore sul cui rotore sono disposte le palette a geometria variabile della turbina intubata che completa l’aerogeneratore. Il tubo svolge funzioni di accelerazione deM’aria, in combinazione con la carenatura a ogiva del rotore, di riduzione delle turbolenze e protezione delle palette della turbina L’alternatore refrigerato a liquido ha la particolari tà di avere l’intensità magnetica variabile ottenuta variando la distanza fra i magneti del rotore dalle bobine dello statore. The optical equipment is integrated into the stator of an alternator on whose rotor the variable geometry blades of the ducted turbine that complete the wind turbine are arranged. The tube performs functions of air acceleration, in combination with the ogive fairing of the rotor, of turbulence reduction and protection of the turbine blades. distance between the rotor magnets and the stator coils.

Per quanto riguarda eventuali precedenti storici, allo stato attuale della tecnica, non si ha notizia dell’esistenza di precursori con caratteristiche tec niche tali da essere presi in esame per eventuali confronti di similitudini. As regards any historical precedents, in the current state of the art, there is no news of the existence of precursors with technical characteristics such as to be taken into consideration for any comparisons of similarities.

Per comprendere al meglio la descrizione tecnica del trovato in oggetto d’esposizione sono allegate due tavole di disegni dove, a solo titolo illustrativo e per nulla limitativo, sono rappresentate: To better understand the technical description of the invention in question, two tables of drawings are attached where, for illustrative purposes only and not at all limiting, the following are shown:

- Le figg.1 e 2 che mostrano l’aerogeneratore solare in due viste assonometriche anteriore e posteriore. - Figs. 1 and 2 which show the solar wind turbine in two axonometric front and rear views.

- Le figg.3, 4 e 5 che mostrano rispettivamente, gli apparati ottici separati con vista nello spazio, la cella fotovoltaica vista frontalmente e una sezione laterale dell'insieme. - Figs. 3, 4 and 5 which respectively show the separate optical apparatuses with a view into space, the photovoltaic cell seen from the front and a side section of the assembly.

- Le figg.6 e 7 che mostrano statore e rotore senza condotto e carena con i meccanismi di controllo degli assetti delle palette con le posizioni relative di rotore e statore per venti deboli e venti forti in due viste laterali. - La fig.8 che mostra statore e rotore separati nello spazio con vista dei particolari interni. In riferimento a fig. 1 l’aerogeneratore solare (1) è formato dal sistema fotovoltaico a concentrazione che comincia dal filtro infrarosso (15) e dal sistema eolico a turbina parzialmente statica con le palette (25) contenute dentro il tubo (7). - Figs. 6 and 7 which show stator and rotor without duct and hull with the mechanisms for controlling the attitude of the blades with the relative positions of rotor and stator for light winds and strong winds in two side views. - Fig. 8 which shows the stator and rotor separated in space with a view of the internal details. With reference to fig. 1 the solar wind turbine (1) is formed by the concentrating photovoltaic system that starts from the infrared filter (15) and the partially static turbine wind system with the blades (25) contained inside the tube (7).

Con riferimento anche alla fig. 2 la carena (4) con le razze (5) si unisce all’ogiva (6). With reference also to fig. 2 the hull (4) with the spokes (5) joins the ogive (6).

Frontalmente a questa c’è l’ogiva del rotore (20). L’insieme di forme di tubo e rotore da origine ad un condotto a sezione decrescente dove l’aria di passaggio entra dalla parte più ampia, esce dalla parte più stretta e durante il transito nel condotto mentre cede parte della sua energia cinetica alle palette contemporaneamente accelera per effetto della sezione decrescente. In front of this there is the rotor ogive (20). The set of shapes of tube and rotor gives rise to a duct with a decreasing section where the passing air enters from the widest part, exits from the narrowest part and during the transit in the duct while giving part of its kinetic energy to the vanes at the same time accelerates due to the decreasing section.

L’aerogeneratore è sorretto dalla torretta (2) che gli consente i moti di rotazione sull’asse verticale della torretta stessa e sull’asse del perno (3). Con riferimento alle figg.3, 4 e 5 i raggi del sole attraversano il filtro infrarosso (15), sono riflessi dallo specchio parabolico (11), ricavato nel corpo dello statore (8), sullo specchio divergente (16) che li riflette nel convogliatore (14), con le pareti interne a specchio, che a sua volta li reindirizza quasi rettilinei sulla cella fotovoltaica (13) contenuta nella sede (12). I condotti di carico e scarico (9 e 10) sono per il fluido di raffreddamento degli elementi che sviluppano calore. The wind turbine is supported by the turret (2) which allows it to rotate on the vertical axis of the turret itself and on the axis of the pivot (3). With reference to figs. 3, 4 and 5, the sun's rays pass through the infrared filter (15), they are reflected by the parabolic mirror (11), obtained in the stator body (8), on the divergent mirror (16) which reflects them in the conveyor (14), with mirrored internal walls, which in turn redirects them almost straight to the photovoltaic cell (13) contained in the seat (12). The inlet and outlet ducts (9 and 10) are for the cooling fluid of the elements that develop heat.

La caratteristica innovativa di questo aerogeneratore solare è l'equilibratura automatica della coppia motrice della turbina in funzione della coppia resistente dell’alternatore. The innovative feature of this solar wind turbine is the automatic balancing of the turbine's drive torque as a function of the alternator's resistant torque.

La coppia motrice è regolata dall'inclinazione delle palette quella resistente dall’interazione magnetica, generata dalla distanza fra le bobine e i magneti. Come da fig.6, 7 e 8 le palette (25) sono dotate di camme (24) calettate negli alberini (23) inseriti nel piatto (21). La loro incidenza rispetto al vento è regolata dai pistoni (26) spinti da molle contro le camme, con i venti deboli sono molto inclinate e con i venti forti poco inclinate. Parallelamente e contemporaneamente con venti deboli il piatto (21), che contiene i magneti (22), è distante dalle bobine (17) mentre con venti forti è molto vicino. L’avanzamento del piatto con i magneti verso le bobine dello statore per effetto dell’attrazione magnetica è contrastato dalle molle a tazza (19). The drive torque is regulated by the inclination of the blades, the one resistant to the magnetic interaction, generated by the distance between the coils and the magnets. As shown in fig. 6, 7 and 8, the vanes (25) are equipped with cams (24) keyed into the shafts (23) inserted in the plate (21). Their incidence with respect to the wind is regulated by the pistons (26) pushed by springs against the cams, with low winds they are very inclined and with strong winds little inclined. At the same time and at the same time with weak winds the plate (21), which contains the magnets (22), is far from the coils (17) while with strong winds it is very close. The advancement of the plate with the magnets towards the stator coils due to the effect of the magnetic attraction is opposed by the cup springs (19).

Fra le bobine (17) ci sono le serpentine (18) del liquido di raffreddamento. Between the coils (17) are the coils (18) of the coolant.

Nel complesso questo aerogeneratore solare ha il vantaggio di operare con due fonti energetiche e per quanto riguarda il sistema eolico ha un’ampia estensione operativa su una scala di velocità del vento ineguagliabile da qualsiasi aerogeneratore esistente. Overall, this solar wind turbine has the advantage of operating with two energy sources and as regards the wind system it has a wide operational range on a wind speed scale unmatched by any existing wind turbine.
