Movable object type high-efficiency wave energy apparatus

A movable object type high-efficiency wave energy apparatus comprising floating bodies floating on a sea surface to convert upward and downward movement of waves generated by wind into electric energy, wherein

• one of the floating bodies and a neighboring one of the floating bodies are connected to each other via a coupler,
• the coupler comprises:
• left and right bodies;
• a horizontal rotary shaft and a vertical rotary shaft connected to each other via a middle hinge shaft to connect the left and right bodies to each other;
• ram connection units to connect accumulators mounted to the left and right bodies to the horizontal and vertical rotary shafts;
• and electric power converters having electric generators connected to the accumulators, connected to the respective ram connection units, via refrigerators mounted therein,
• the electric generators of the electric power converters disposed at the left and right bodies are connected to a concrete dock installed on a sea floor via a Vectran wire, and
• a submarine cable connected to the Vectran wire through the concrete dock supplies electricity to land via a power station and a power line.
