Floating apparatus for wave power generation

A floating apparatus for wave power generation, the apparatus comprising:

• a floating unit floating on a sea surface;
• an energy unit configured to convert a kinetic energy of the floating unit to an electric or hydraulic energy;
• and
• a transfer unit configured to transfer the kinetic energy of the floating unit to the energy unit, wherein the transfer unit and the energy unit are provided at an inside of the floating unit;
• an energy smoothing unit generating a restoring force to allow the floating unit to return to an initial position, or smoothing a generation amount of the energy unit;
• anchoring units fixed to a sea bottom surface;
• anchoring wires having one distal ends connected to the anchoring units and the other distal ends connected to the transfer unit;
• weight wires having one distal ends connected to the transfer unit and the other distal ends connected to the energy smoothing unit;
• wherein when a tension increases on the anchoring wires by a periodic motion of a wave, an energy applied to the anchoring wires is transmitted to the energy unit, and when the tension of the anchoring wires decreases, a potential energy stored in the energy smoothing unit is transmitted to the energy unit;
• the transfer unit includes an anchoring shaft wound by the anchoring wires and a weight shaft wound by the weight wires, and a rotational force of the weight shaft and a rotational force of the anchoring shaft are transmitted to the energy unit;
• the anchoring wires and the weight wires are mutually separated and independently connected to the anchoring shaft through a first one-way clutch and the weight shaft through a second one-way clutch, respectively;
• a tension of at least one of the anchoring wires and the weight wires is transmitted to the energy unit through at least one of the first and second one-way clutches;
• and
• the energy unit absorbs translational and rotational kinetic energy of the floating unit;
• wherein the floating unit further comprises passage units, and the number of the anchoring wires is the same as the number of the passage units;
• each anchoring wire is connected to the transfer unit through each passage unit
• the anchoring wires are connected to the transfer unit by being inserted from an outside to an inside of the floating unit through the passage units;
• and
• the passage units are spaced apart to absorb translational and rotational kinetic energy through the anchoring wires;
• the anchoring wires comprise at least three anchoring wires, two of the three anchoring wires having the one distal ends connected to the anchoring units to be fixed to the sea bottom surface and the other distal ends connected to the transfer unit through the passage units;
• the passage units comprises three passage units arranged in a way that, an extending line on which two of the passage units are positioned, and the remaining passage unit is spaced apart from the extending line at a predetermined distance.
