Claims (3)

It is a wave energy conversion device that converts wave energy into rotational energy in a certain direction, and balances floating bodies on the sea surface with the counterweight on the land side with a balancing rope, making it movable according to the vibration of the waves At the same time, the floating body is locked to the base of the seabed with sufficient slack with a locking rope with a length equivalent to the maximum wave height normally predicted, and further energy transfer means such as land-side balancing rope Are connected to a rotation conversion mechanism comprising two sets of free gears with a built-in latitudinal mechanism, a set of reversing gears, and an output rotating shaft. 2. The wave energy conversion device according to claim 1, wherein the rotation conversion mechanism includes two sets of free gears, a hydraulic pump and a set of hydraulic circuits, a hydraulic motor, and an output rotation incorporated in a latitudinal mechanism mounted with rotation directions opposite to each other. It is characterized by comprising a shaft or a set of reversible hydraulic pump and hydraulic circuit, hydraulic motor and output rotating shaft. 3. The wave energy conversion device according to claim 1 or 2, wherein the floating bodies of the plurality of sets of wave energy conversion devices have different distances and positions on the same line according to the predicted traveling direction and wavelength of the wave. The output rotation shafts of the respective rotation conversion mechanisms are the same output rotation shaft.
