Wave Power Generating Apparatus

摘要

A wave power generating apparatus is provided. A generator including a housing and a drive shaft coupled to the housing is coupled to a floating part that is floatable on a sea. The drive shaft is positioned on an extension of the center of rotation extending from the housing. A first rotary unit is coupled to the generator housing, is rotatable in a first direction together with the housing about the extension of the center of rotation, and includes a first blade able to pivot about a first pivot axis perpendicular to the extension of the center of rotation. A second rotary unit is coupled to the drive shaft of the generator, is rotatable in a second direction opposite to a direction in which the first rotary unit rotates, and includes a second blade able to pivot about a second pivot axis perpendicular to the extension of the center of rotation.

1. A wave power generating apparatus comprising:
a floating part floatable on a sea; a generator coupled to the floating part, wherein the generator comprises a housing and a drive shaft coupled to the housing, the drive shaft being positioned on an extension of a center of rotation extending in a top-bottom direction from the housing; a first rotary unit coupled to the housing of the generator, the first rotary unit being rotatable in a first direction together with the housing about the extension of the center of rotation, wherein the first rotary unit comprises a first blade able to pivot about a first pivot axis perpendicular to the extension of the center of rotation; and a second rotary unit coupled to the drive shaft of the generator, the second rotary unit being rotatable together with the drive shaft in a second direction opposite to a direction in which the first rotary unit rotates, wherein the second rotary unit comprises a second blade able to pivot about a second pivot axis perpendicular to the extension of the center of rotation, wherein, when the generator, the first rotary unit and the second rotary unit are moved upwardly and downwardly in water by waves in a state in which the floating part is on a surface of sea and the first rotary unit and the second rotary unit are underwater, the first blade and the second blade rotate the housing and the drive shaft in opposite directions with a force from water applied to each of the first and second blades, such that the generator generates electricity.
