NOVELTY - The apparatus has floating bodies (118) floating on a sea surface to convert upward and downward movement of waves generated by wind into electric energy, where the floating bodies are connected to each other by a coupler (101). The coupler comprises electric power converters having electric generators that are connected to a concrete dock (113) installed on a sea floor via a vectran wire (112). A submarine cable (114) connected to the vectran wire through the concrete dock supplies electricity to land via a power station (115) and a power line (116).    USE - Movable object type high-efficiency wave energy apparatus.    ADVANTAGE - The apparatus accelerates vibration or upward and downward movement of the floating bodies according to vibration of waves to convert kinetic energy obtained by amplifying the vibration into electric energy, thus maximizing electric power generation efficiency. The apparatus prevents deterioration in safety of the floating bodies caused in a windstorm or in abnormal weather, eliminates the necessity of a mooring device for its repair, and prevents movement of the floating bodies. The apparatus produces electric power even when the height of waves is low. The submarine cable connected to the vectran wire through the concrete dock supplies electricity to land via the power station and the power line, thus eliminating the necessity of an additional ocean structure. The floating bodies are conveyable to a seaside warehouse for repair of the apparatus during abnormal weather, thus achieving convenience and safety in repair. The apparatus is operated through remote monitoring and control, thus improving operational efficiency. The apparatus has much higher economy, safety and functional effects.
