Patent ID: 8304925

Claim:
A movable object type high-efficiency wave energy apparatus, comprising floating bodies floating on a sea surface to convert upward and downward movements of waves generated by wind into electric energy, wherein each of the floating bodies includes a variable liquid column oscillator, and neighboring ones of the floating bodies are connected to each other via a coupler, wherein the coupler comprises: left and right bodies of the floating 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; and ram connection units configured to connect the horizontal and vertical rotary shafts with electric power converters disposed in left and right bodies for converting rotational movements of the horizontal and vertical rotary shafts into respective rectilinear movements to compress operating oil, wherein the electric power converters comprise: accumulators connected to respective ones of the ram connection units for storing the operating oil compressed by the ram connection unit; coolers connected to the accumulators and configured to cool the oil; and electric generators for converting the oil compressed and stored in the accumulators into electric power, wherein 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 wherein a submarine cable connected to the VECTRAN ® wire through the concrete dock supplies electricity to land via a power station and a power line.
