Position-controlled wave power generating apparatus

A position-controlled wave power generating apparatus comprising:

• a floating part floatable on a body of water;
• a motion conversion unit coupled to the floating part, wherein the motion conversion unit converts a vertical motion caused by energy of waves into to a rotational motion;
• a power generating unit generating electricity using a generator connected to the motion conversion unit;
• and
• a position control unit positioned below a water surface to generate a thrust from the energy of waves, the position control unit being connected to the motion conversion unit by means of a mooring member having a predetermined length,
• wherein the generator comprises a housing and a drive shaft coupled to the housing, the drive shaft being positioned on an extension line extending in a top-bottom direction from a center of rotation of the housing,
• wherein the motion conversion unit comprises:
• a first rotary part coupled to the housing of the generator, the first rotary part being rotatable together with the housing in a first direction about the extension line of the center of rotation;
• and
• a second rotary part coupled to the drive shaft of the generator, the second rotary part being rotatable together with the housing in a second direction opposite to the first direction,
• wherein the first rotary part comprises a first frame coupled to the housing of the generator and a first rotary blade disposed on the first frame, the first rotary blade configured to pivot about a first pivot axis perpendicular to the extension of the center of rotation,
• wherein the second rotary part comprises a third frame coupled to the drive shaft of the generator and a second rotary blade disposed on the third frame, the second rotary blade configured to pivot about a second pivot axis perpendicular to the extension of the center of rotation.
