Abstract
A device for generating electric energy (1) from a renewable source, in particular from wave energy, comprising an oscillating device (2) that can transform the thrust of a natural agent on the first extremity of oscillating device (2) into kinetic energy; a motor unit, operatively connected to a second extremity of the oscillating device in such a way as to receive the kinetic energy transmitted by the oscillating device (2); and an electrical rotating machine operatively connected to the motor unit and suitable for producing electricity when it is set to rotating by the said motor unit.

Device for generating electricity (1) from wave energy, comprising:
- an oscillating device (2), able to transform the thrust of a wave on a first extremity of the oscillating device (2) into kinetic energy;
- a motor unit, operatively connected to a second extremity of the oscillating device so as to receive the kinetic energy transmitted to it by the oscillating device (2);
- an electrical rotating machine operatively connected to the motor unit and able to produce electric energy when made to rotate by said motor unit, wherein said oscillating device comprises a first thrust lever (4;
- 4″) with an essentially vertical extension and having a lower extremity (8) of a concave shape able to receive a thrust from the sea waves acting essentially in a horizontal direction, and a second thrust lever (4′) with an essentially horizontal extension and carrying a float (108;
- 108′) at one extremity,
- wherein said first thrust lever (4″) is hinged to the second thrust lever (4″) so as to freely oscillate and is positioned close and behind the float with respect the wave direction such that, when the float reaches the crest of the wave, the lower extremity of the first thrust lever (4′) is raised above the surface of the water.
Method of transformation of the energy produced by the thrust force of a wave into electricity, comprising steps of:
- capturing the thrust of the wave by means of an oscillating device;
- converting the oscillation movement of the oscillating device into rotating movement by means of a pressure multiplier;
- transmitting said movement to the rotor of an electrical rotating machine,
- wherein the phase of capturing the thrust of the wave comprises a first phase of capturing the thrust of the wave acting in a horizontal direction by means of a first thrust lever with an essentially vertical extension and having a lower extremity suitable for immersing at least partially in the water at least in said first phase to receive said horizontal thrust, and a second phase of capturing the thrust of the wave acting in a vertical direction by means of a second thrust lever with an essentially horizontal extension and a float at one extremity,
- wherein said first thrust lever is vertically moved by the oscillation of the second thrust lever between a lower position, in which the lower extremity is at least partially immersed in the water, and a raised position, in which said lower extremity is above the surface of the water.
