Abstract
The invention relates to a device comprising a reel around which a cable is wound. One end of the cable is tied to a floating body (buoy) and the other end is connected to a spring or ballast, or to both. The reel is attached to a shaft that acts as the axle, which is rotated by the reel. The axle is connected at both ends to two electricity generators by a special connector. All of the components are attached to a base that floats on the surface of the water and that is tied to the seabed or to suitable ballast (or similar). When the buoy rises under the effect of an incoming wave, pulling the cable, which makes the reel rotate, and also when the buoy descends under the effect of the spring or the counter ballast, the special connector rotates the generator, thereby generating energy. The device comprises: points for attachment to the seabed; a cable or other means of attachment; attachment points; a base; carriers; an electricity generator; a special connector for transferring movement; an axle; bearings; a reel; a cable wound around the reel; a buoy; and counter ballast.
