PCT/BR2013/000018VIANI, DelcioVIANI, Delcio
Capturing kinetic energy from aquatic waves to generate electrical energy; • Energy generated by waves; • Alternative energies; • Sustainable generation of electrical energy. The basic concept of this patent is to generate electrical energy through the oscillations of sea waves in conjunction with the principles of gravitational force and pull with pendular rotational movement that transforms the potential energy absorbed into mechanical energy, and subsequently electrical energy. The concept applied in the preferred embodiment thereof in principle includes a parent platform, strategically positioned above the waterline in a location that has a historically regular wave pattern, and which can therefore be used as the energy source, transferring the oscillations by means of thrust to the cells isolated in the spaces thereof inside the platform, and inside each cell, a pendular rotor that is subject to gravitational force rotates in the direction of the drop, actuating the drive shaft (EM) in the center of the apparatus, which transfers the mechanical energy to the system, which is able to generate electrical energy, directly to a generating set or indirectly by means of a hydraulic system, with separate pumps, and that in series produce a stream to the generating station, which may be on the platform or on land, depending on the location distance and positioning.
