SEA WAVE AND TIDE TRACKING HYDROELECTRIC PLANT WITH HEIGHT TANK FILLING, AND CORRESPONDING POSITIONING METHOD

Resumen de: WO2025017379A1

The present invention relates to a new sea wave and tide tracking hydroelectric plant, for the production of electricity by exploiting the energy of sea waves which, conveyed within converging, focused and concentrated gates, are capable of overcoming the vertically movable banks of an elevated tank unit with variable capacity, by virtue of oblique artificial shorelines, the uppermost portion of which will be articulated and integral with the top of said movable banks. The water trapped high up in the tank unit will be free to fall at only one side of the rotors having shaped and counter rotating blades, forming the underlying turbine units, referred to as " Spin Turbines". The cascading water in the uncovered sectors of the turbine unit will generate a weight imbalance which will cause the rotors to rotate until the tank unit is completely emptied. The alternators or dynamos connected to the toothed side caps of the rotors will transform the mechanical energy into electricity. The turbine units will be liftable in a synchronized manner when arranged in sets, and the top of each will also form a portion of the base of the variable-capacity raised tank unit. The height of the turbine units and that of the movable banks, and therefore of the inclined planes, will be defined by an automation system which will have the task of optimizing the production of electricity in consideration of the tide height, the wave height, and the sensors installed in the plant.
