Description

DESCRIZIONE del brevetto per invenzione industriale avente per titolo: “Apparato per la produzione di energia dal moto ondoso”, DESCRIPTION of the patent for industrial invention entitled: "Apparatus for the production of energy from wave motion",

TESTO DELLA DESCRIZIONE TEXT OF THE DESCRIPTION

La presente invenzione riguarda un apparato per la produzione di energia dal moto ondoso. The present invention relates to an apparatus for the production of energy from wave motion.

Nel settore delle energie cosiddette rinnovabili sono noti studi e impianti sperimentali per ricavare energia termica o meccanica dal moto ondoso o dalle maree e trasformarla quindi in energia elettrica. Tali impianti si basano generalmente su l’utilizzo di galleggianti, i quali, se opportunamente collegati con dei generatori di corrente, trasformano il loro moto oscillatorio causato dalle onde marine in energia elettrica. Tali impianti si rivelano tuttavia piuttosto complessi, costosi e dal rendimento limitato. In the field of so-called renewable energies, studies and experimental plants are known to obtain thermal or mechanical energy from wave motion or tides and then transform it into electricity. These systems are generally based on the use of floats, which, if properly connected with current generators, transform their oscillatory motion caused by sea waves into electrical energy. However, these plants prove to be rather complex, expensive and with limited performance.

Lo scopo della presente invenzione è un apparato per la produzione di energia dal moto ondoso che sia economico, efficiente e di semplice realizzazione. The object of the present invention is an apparatus for the production of energy from wave motion which is economical, efficient and easy to make.

Tale scopo viene raggiunto dalla presente invenzione mediante un apparato per la produzione di energia dal moto ondoso, comprendente almeno un galleggiante posizionato in acqua e atto a oscillare verso l’alto o verso il basso a causa del moto ondoso a cui viene sopposto, caratterizzato dal fatto che detto galleggiante è collegato, mediante degli organi di trasmissione provvisti di un meccanismo a ruota libera, ad un albero solidale ad un volano ed atto ad essere accoppiato con dei mezzi di generazione di energia elettrica; in un primo moto verso l’alto o verso il basso del galleggiante, tali organi sono atti a trasmettere all’albero un moto rotatorio in una determinata direzione e, in un secondo moto del galleggiante in direzione opposta a tale primo moto, tale albero è atto a mantenere la propria rotazione, grazie alla massa inerziale del volano posto in rotazione in tale primo moto e al meccanismo a ruota libera. This object is achieved by the present invention by means of an apparatus for the production of energy from wave motion, comprising at least one float positioned in the water and able to oscillate upwards or downwards due to the wave motion to which it is supported, characterized by the fact that said float is connected, by means of transmission members provided with a free wheel mechanism, to a shaft integral with a flywheel and capable of being coupled with means for generating electrical energy; in a first upward or downward motion of the float, these members are able to transmit a rotary motion to the shaft in a given direction and, in a second motion of the float in the opposite direction to said first motion, said shaft is able to maintain its rotation, thanks to the inertial mass of the flywheel rotated in said first motion and to the freewheel mechanism.

Ulteriori caratteristiche e vantaggi della presente invenzione verranno meglio compresi nel corso della seguente descrizione, considerata a titolo esemplificativo e non limitativo e riferita ai disegni allegati, nei quali: Further characteristics and advantages of the present invention will be better understood in the course of the following description, considered by way of non-limiting example and referring to the attached drawings, in which:

- la fig. 1 illustra un vista in elevazione laterale del presente apparato per la produzione di energia dal moto ondoso; - fig. 1 illustrates a side elevation view of the present apparatus for producing energy from wave motion;

- la fig. 2 illustra una vista in scala minore dell’apparato di fig. 1 in una determinata fase di funzionamento; e - fig. 2 shows a smaller scale view of the apparatus of fig. 1 in a given operating phase; And

- la fig. 3 illustra un’ulteriore vista in scala minore dell’apparato di fig. 1 in un’ulteriore fase di funzionamento. - fig. 3 illustrates a further view on a smaller scale of the apparatus of fig. 1 in a further phase of operation.

Con riferimento a tali disegni allegati e con particolare riferimento alla fig. 1 degli stessi, con 1 è indicato un galleggiante atto a sfruttare il moto ondoso, quindi posizionato ad esempio in mare, e con 2 è indicato un volano collocato sulla terra ferma o su un natante ed avente un’adeguata massa ed un adeguato diametro. Tale galleggiante 1 è collegato, inferiormente, ad una prima estremità di un cavo 4, che viene rinviato attorno ad un rullo folle 5. L’altra estremità del cavo 4 è collegata mediante un giunto 7 ad una prima estremità di una cinghia o di una catena 8, la quale viene rinviata attorno ad una puleggia o ad una ruota dentata 9 e la cui altra estremità è collegata ad un contrappeso 10. All’estremità della base 6 della struttura 1 1 di sostegno opposta a quella nella quale è posizionato il galleggiante 1 è posizionato un montante 12 di supporto di un albero 13, atto a essere posto in rotazione dalla rotazione della ruota dentata 9 e del volano 2, come verrà descritto in seguito nel funzionamento dell’apparato. Tale ruota dentata 9 è collegata all’albero 13 mediante un meccanismo 14 a ruota libera, pertanto, come è di per sé noto, tale albero 13 sarà posto in rotazione dalla ruota dentata 9 solo se quest’ultima gira in un determinato verso, mentre nel verso opposto tale albero 13 risulterà folle. Il volano 2 è solidale a tale albero 13, il quale agisce come una presa di forza e ad esso potrà essere collegato ad esempio il rotore di un alternatore per la trasformazione dell’energia cinetica in energia elettrica. With reference to these accompanying drawings and with particular reference to fig. 1 of the same, 1 indicates a float suitable for exploiting the wave motion, therefore positioned for example in the sea, and 2 indicates a flywheel placed on land or on a vessel and having an adequate mass and an adequate diameter. This float 1 is connected, at the bottom, to a first end of a cable 4, which is returned around an idle roller 5. The other end of the cable 4 is connected by means of a joint 7 to a first end of a belt or a chain 8, which is returned around a pulley or a toothed wheel 9 and whose other end is connected to a counterweight 10. At the end of the base 6 of the support structure 11 opposite to that in which the float is positioned 1 there is positioned an upright 12 supporting a shaft 13, able to be rotated by the rotation of the toothed wheel 9 and the flywheel 2, as will be described later in the operation of the apparatus. This toothed wheel 9 is connected to the shaft 13 by means of a free wheel mechanism 14, therefore, as is known per se, this shaft 13 will be set in rotation by the toothed wheel 9 only if the latter rotates in a certain direction, while in the opposite direction, this shaft 13 will be idle. The flywheel 2 is integral with this shaft 13, which acts as a power take-off and can be connected to it, for example, the rotor of an alternator for the transformation of kinetic energy into electrical energy.

Il presente apparato sfrutta il moto di sollevamento e abbassamento delle onde, ad esempio le onde marine, pertanto, si vedano le figg. 2 e 3 dei disegni allegati, il moto di una qualunque onda O provoca l’innalzamento, fig. 2, o l’abbassamento, fig. 3, del galleggiante 1. L’innalzamento del galleggiante 1 provoca l’innalzamento del cavo 4 e la traslazione della catena 9, la quale pone in rotazione la ruota dentata 9 in direzione della freccia R. La ruota dentata 9 trasmette tale moto rotatorio all’albero 13 e al volano 2 e contemporaneamente anche il contrappeso 10 si solleva di una certa quota. Quando il galleggiante si abbassa in seguito all’abbassamento dell’onda O, si veda la fig. 3, la ruota dentata 9 ruoterà in direzione opposta a quella indicata dalla freccia R, ma l’albero 13, grazie al meccanismo 14 a ruota libera e all’azione della massa inerziale del volano 2, continuerà a ruotare in direzione della freccia R di fig. 2. Il contrappeso 10, che si abbassa, contribuisce a riportare il galleggiante 1 nella posizione abbassata. The present apparatus exploits the lifting and lowering motion of the waves, for example sea waves, therefore, see figs. 2 and 3 of the attached drawings, the motion of any wave O causes the rise, fig. 2, or lowering, fig. 3, of the float 1. The raising of the float 1 causes the lifting of the cable 4 and the translation of the chain 9, which rotates the toothed wheel 9 in the direction of the arrow R. The toothed wheel 9 transmits this rotary motion to the shaft 13 and the flywheel 2 and at the same time also the counterweight 10 is raised by a certain height. When the float is lowered following the lowering of the O wave, see fig. 3, the toothed wheel 9 will rotate in the opposite direction to that indicated by the arrow R, but the shaft 13, thanks to the freewheel mechanism 14 and the action of the inertial mass of the flywheel 2, will continue to rotate in the direction of the arrow R. fig. 2. The counterweight 10, which is lowered, helps to bring the float 1 back into the lowered position.

Come accennato precedentemente, all’albero 13 potrà essere collegato un alternatore per la produzione di energia elettrica. La massa e le dimensioni del volano 2 saranno scelte di volta in volta in funzione delle diverse esigenze di sfruttamento del presente apparato, così come l’estensione della struttura 1 1 di supporto, che stabilisce la distanza tra il galleggiante 1 collocato in acqua e il volano 2 collocato sulla terra ferma o su un adatto natante. As mentioned previously, an alternator for the production of electricity can be connected to shaft 13. The mass and dimensions of the flywheel 2 will be chosen from time to time according to the different exploitation needs of this apparatus, as well as the extension of the support structure 11, which establishes the distance between the float 1 placed in the water and the flywheel 2 placed on land or on a suitable vessel.
