Questo ed altri scopi, che meglio appariranno evidenziati in seguito, sono raggiunti da un'apparecchiatura per la generazione di energia elettrica attraverso lo sfruttamento delle correnti marine e dei corsi d'acqua in generale, caratterizzata dal fatto di comprendere un sistema di supporto di un generatore immerso in acqua e costituito da un rotore contenuto in un condotto ad effetto Venturi; il sistema di supporto è atto a trattenere sul fondo il generatore o a mantenerlo sospeso vicino alla superficie. This and other purposes, which will be better highlighted later, are achieved by an apparatus for the generation of electrical energy through the exploitation of sea currents and watercourses in general, characterized by the fact that it includes a support system for a generator immersed in water and consisting of a rotor contained in a Venturi effect duct; the support system is able to hold the generator on the bottom or to keep it suspended close to the surface.
Il generatore vero e proprio comprende un condotto per il passaggio dell'acqua, un rotore bidirezionale, con elica a tre o più pale, un moltiplicatore di giri, un albero di trasmissione, ed un generatore di corrente collegato ad un sistema di controllo. The actual generator comprises a conduit for the passage of water, a bidirectional rotor, with a propeller with three or more blades, a speed multiplier, a transmission shaft, and a current generator connected to a control system.
Ulteriori caratteristiche e vantaggi dell'oggetto del presente trovato risulteranno maggiormente evidenziati attraverso un esame della descrizione di una forma di realizzazione preferita, ma non esclusiva, del trovato, illustrata a titolo indicativo e non limitativo nei disegni allegati, in cui: Further characteristics and advantages of the object of the present invention will become more evident through an examination of the description of a preferred, but not exclusive, embodiment of the invention, illustrated by way of non-limiting example in the attached drawings, in which:
