    OBJECTIVE OF THE INVENTION
    The object of the present invention, called PLANT AND OPERATION PROCEDURE FOR THE CONVERSION OF UNDIMOTRIC ENERGY TO ELECTRICAL ENERGY VIA PUMPS AND ALTERNATIVE HYDRAULIC MOTORS, is the production of electrical energy from the energy of marine waves by means of alternative accumulation pumps. Hydraulic potential energy to be converted to electric energy via alternative double-acting motors capable of transforming the alternative movement to rotary movement using one of the conversion systems from translation to translation movement:
    - the crank-crankshaft system (comprising rod-crosshead-skate-rod) or alternatively,
    - the double-rack-gear system (complete converter of movement from translation to rotation movement by means of the double-rack-gear system), which transforms the movement from alternative to continuous rotation movement capable of being coupled to a generator electric. The alternative pumps of accumulation of hydraulic potential energy are driven by the effect of sea waves when acting on floats or buoys that take advantage of the vertical movement of the waves to generate alternative displacement force capable of operating the aforementioned alternative pumps. Alternative hydraulic potential energy accumulation pumps are driven by any wave energy capture mechanism of the alternative linear displacement movement type.

    BACKGROUND OF THE INVENTION
    Converting plants from wave energy to electrical energy via mechanical energy that operate with alternative machines convert the alternative movement to rotary movement using turbines or rotary hydraulic motors that drive electric generators to convert wave energy to electrical energy, which leads to performance losses 12% associated with the efficiency of turbines or hydraulic motors. In order to increase the conversion efficiency, the use of alternative double-acting motors is proposed, for which a plant equipped with alternative machines (both for pumping and for driving electric generators) is used, converting the alternative movement to continuous rotary motion, either by means of the rod-crank-crankshaft system (by means of a cross-slide-skate-connecting rod mechanism), or the double-rack system with rotating gear. Based on the principle of operation of the invention, technologies for converting wave energy to electrical energy of this nature are not known.
    DESCRIPTION OF THE BRIEF INVENTION DESCRIPTION OF THE INVENTION
    The PLANT AND OPERATION PROCEDURE FOR THE CONVERSION OF UNDIMOTRIC ENERGY TO ELECTRICAL ENERGY VIA PUMPS AND ALTERNATIVE HYDRAULIC MOTORS converts the discontinuous alternative rectilinear movement from the sea waves to continuous rotation movement to drive an electric generator.

The transferred hydraulic work fluid is accumulated in a hydropneumatic tank, accumulating hydraulic potential energy. The potential hydraulic energy is used to drive one or more dual-acting alternative hydraulic motors (each of which consists of a double-acting actuator cylinder).

The alternative movement from the marine waves generated by means of floats, buoys, or devices that perform the same function, is used to drive alternative double-acting pumps (10), which transfer a working hydraulic fluid such as seawater in open circuit, or fresh water in closed circuit. The working hydraulic fluid transferred by the double-acting alternative pumps (10) is accumulated in a hydropneumatic potential energy accumulator (12) consisting of a hydropneumatic reservoir, accumulating hydraulic potential energy. The potential hydraulic energy is used to drive one or more dual-acting alternative hydraulic motors (16) (each of which consists of a double-acting actuator cylinder).
