Description

DESCRIZIONE dell’invenzione avente PER TITOLO DESCRIPTION of the invention having THE TITLE

“Convertitore per convertire in energia elettrica la rotazione di un corpo basculante per l’azione delle onde”. "Converter to convert the rotation of a rocking body due to the action of waves into electricity".

Stato arte State of the art

Attualmente per convertire in energia elettrica il movimento basculante di un corpo posto in mare che oscilla per l’azione delle onde, oscillazioni che possono avvenire dall'alto in basso oppure attorno ad un asse, sia che detto corpo sia posto sulla linea di costa, o vicino o lontano dalla costa, viene utilizzato un pistone esterno al corpo e ad esso operativamente vincolato che mette in pressione dell’acqua che viene poi trasferita in altra zona e utilizzata per generare energia elettrica. All’uopo si veda il brevetto EPO n. wo2004097212 ed altri. Sistema complesso con meccanismi che lavorano a contatto con l’ambiente marino. Currently, to convert into electrical energy the rocking movement of a body placed in the sea that oscillates due to the action of the waves, oscillations that can occur from top to bottom or around an axis, whether said body is placed on the coast line, o near or far from the coast, a piston external to the body is used and operatively linked to it, which pressurizes the water which is then transferred to another area and used to generate electricity. For this purpose, see EPO patent no. wo2004097212 and others. Complex system with mechanisms that work in contact with the marine environment.

Invenzione Invention

Con la presente invenzione si è ovviato a tali inconvenienti realizzando un convertitore col suo meccanismo posto tutto all’interno del corpo stesso senza alcuna parte a contatto con l’acqua, tranne il cavo elettrico per condurre a terra l’elettricità prodotta, da usarsi in particolare per il dispositivo. With the present invention these drawbacks have been overcome by realizing a converter with its mechanism placed entirely inside the body itself without any part in contact with water, except the electric cable to conduct the electricity produced to earth, to be used in particular for the device.

L’invenzione consiste quindi in un convertitore per convertire in energia elettrica il movimento basculante di un corpo posto in mare che sfrutta il movimento relativo di rotazione che si instaura per azione delle onde tra i due perni principali di sostegno ai quali il corpo è incernierato per il tramite di due boccole principali alle quali è solidale ed il corpo stesso con il suo meccanismo, che opera a seguito di tale movimento rotatorio relativo, posto tutto di detto corpo; meccanismo con una sua parte solidale a detti perni principali e con un’altra sua parte solidale a dette boccole principali che comprende sostanzialmente dei generatori elettrici ad induzione e dei settori di ruota dentata dove lo statore dei generatori elettrici può essere solidale ai perni principali ed in questo caso il relativo rotore viene posto in rotazione da un settore di ruota dentata solidale alla rispettiva boccola principale, oppure lo statore dei generatori elettrici è reso solidale alle boccole di giri agli stessi operativamente vincolato. The invention therefore consists of a converter for converting the tilting movement of a body placed in the sea into electrical energy which exploits the relative rotation movement that is established by the action of the waves between the two main support pins to which the body is hinged to the means of two main bushings to which it is integral and the body itself with its mechanism, which operates as a result of this relative rotational movement, placed entirely in said body; mechanism with a part thereof integral with said main pins and with another part thereof integral with said main bushings which substantially comprises induction electric generators and sectors of toothed wheel where the stator of the electric generators can be integral with the main pins and in in this case, the relative rotor is rotated by a toothed wheel sector integral with the respective main bushing, or the stator of the electric generators is made integral with the rotation bushes operatively constrained thereto.

Nell’ambito di tale compito costituisce uno scopo del presente trovato la realizzazione di un convertitore semplice, di facile realizzazione sicuro ed affidabile, ed all’uopo è stato previsto anche un limitato spostamento assiale dei perni rispetto alle boccole e quindi al corpo, anche per facilitare il posizionamento in loco del trovato nel suo complesso. Within this aim, an object of the present invention is to provide a simple converter, easy to make, safe and reliable, and for this purpose a limited axial displacement of the pins with respect to the bushings and therefore to the body has also been provided, also for facilitate the on-site positioning of the invention as a whole.

Tali ed altre caratteristiche del trovato appariranno evidenti dalla seguente descrizione fatta a titolo di esempio non limitativo di alcune forme esecutive preferite di esso, con riferimento alle figure del disegno allegato in cui: These and other characteristics of the invention will appear evident from the following description given by way of non-limiting example of some preferred embodiments thereof, with reference to the figures of the attached drawing in which:

La Fig. 1) rappresenta una vista del convertitore dall’interno del corpo basculante parzialmente sezionata e con parti schematizzate; Fig. 1) represents a partially sectioned view of the converter from inside the tilting body and with schematic parts;

La fig. 2) rappresenta la sezione secondo l’asse A-A del convertitore di cui alla fig. 1). Fig. 2) represents the section according to the A-A axis of the converter referred to in fig. 1).

Con riferimento alle figure dei disegni allegati al corpo CB posto in mare e basculante a seguito del moto ondoso per il tramite della boccola principale BP alla quale è solidale è concesso di ruotare attorno al perno principale PP che lo sostiene e col quale può avere anche avere un limitato movimento assiale; il perno secondario PS, al quale è solidale il braccio BG, è inserito all’interno ella boccola principale BP, può avere con la stessa un movimento rotatorio relativo senza spostamento assiale e non può ruotare rispetto al perno principale PP sulla cui estremità è calettato pur potendo avere con esso un limitato spostamento assiale; il braccio BS è calettato per il tramite della boccola di centraggio BC, alla quale è solidale, sulla boccola principale BP; lo statore SG del generatore elettrico ad induzione GE è sostenuto dal braccio BG ed allo stesso solidale; il settore di ruota dentata SD è sostenuto dal braccio BS ed allo stesso solidale. Viceversa e diversamente da come rappresentato in Fig. 1), il braccio BS può sostenere lo statore SG del generatore elettrico ad induzione GE ed il braccio BG sostenere il settore di ruota dentata SD. With reference to the figures of the drawings attached to the body CB placed in the sea and tilting following the wave motion through the main bushing BP to which it is integral, it is allowed to rotate around the main pin PP which supports it and with which it can also have limited axial movement; the secondary pin PS, to which the BG arm is integral, is inserted inside the main bushing BP, can have a relative rotational movement with it without axial displacement and cannot rotate with respect to the main pin PP on whose end it is keyed even though being able to have with it a limited axial displacement; the BS arm is keyed by means of the centering bushing BC, to which it is integral, on the main bushing BP; the stator SG of the induction electric generator GE is supported by the arm BG and integral with it; the toothed wheel sector SD is supported by the arm BS and integral with it. Vice versa and unlike as shown in Fig. 1), the arm BS can support the stator SG of the induction electric generator GE and the arm BG can support the toothed wheel sector SD.

La rotazione relativa attorno al perno principale PP a seguito del moto ondoso del corpo CB mette in rotazione, per il tramite del settore di ruota dentata SD e con l’interposizione del moltiplicatore di giri MG, il rotore RE del generatore elettrico GE che trasforma il movimento basculante del corpo CB in energia elettrica. The relative rotation around the main pin PP following the wave motion of the body CB rotates, through the toothed wheel sector SD and with the interposition of the gearbox MG, the rotor RE of the electric generator GE which transforms the rocking movement of the CB body in electrical energy.

Possono essere predisposti opportuni dispositivi, non rappresentati nelle figure, per mettere in rotazione sempre nello stesso senso il rotore RE sia che il corpo CB ruoti in un senso sia che ruoti in senso opposto. Suitable devices, not shown in the figures, can be provided to always rotate the rotor RE in the same direction whether the body CB rotates in one direction or rotates in the opposite direction.

Naturalmente la descrizione di cui sopra è stata fatta a puro titolo d’esempio illustrativo, essendo omessi particolari e dettagli peraltro facilmente intuibili ad un tecnico del ramo. Peraltro numerose varianti e modifiche, in particolare costruttive, sono possibili senza dipartire dall’ambito del trovato, come sopra descritto ed a seguito rivendicato. Of course, the above description was made purely by way of illustrative example, since details and details are omitted which are, moreover, easily understood by a person skilled in the art. Moreover, numerous variations and modifications, in particular constructional, are possible without departing from the scope of the invention, as described above and claimed hereinafter.
