Abstract
Provided herein is an oscillating water column type wave energy converting apparatus that is suspended underwater by a mooring device and system thereof, the apparatus and system comprising an damping plate connected to the mooring device; a post with a hollow of which both ends are open, the post extending vertically upwards from the mooring device; a turbine disposed inside the hollow of the post; and a housing of which its lower end is open and which is disposed at an upper portion of the post, wherein the turbine is rotated by air that flows according to changes in water level inside the hollow of the post.
Claims27
An oscillating water column type wave energy converting apparatus that is suspended underwater by a mooring device, the apparatus comprising:
- an damping plate connected to the mooring device;
- a post with a hollow of which both ends are open, the post extending vertically upwards from the mooring device;
- a turbine disposed inside the hollow of the post;
- and
- a housing of which a lower end is open, the housing disposed at an upper portion of the post,
- wherein the turbine is rotated by air that flows according to changes in water level inside the hollow of the post, and
- wherein the damping plate comprises an insertion hole where the post is inserted and combined.
An oscillating water column type wave energy converting system, the system comprising:
- a wave energy converting apparatus comprising a housing of which a lower end is open, an damping plate comprising an insertion hole, a post having a hollow inserted into the insertion hole of the damping plate and extended to an inner space of the housing, and a turbine disposed inside the hollow of the post and is rotated by air that flows according to changes in water level inside the hollow;
- and
- a mooring device that fixates the wave energy converting apparatus and prevents the wave energy converting apparatus from drifting away,
- wherein the housing has a greater diameter than the post, and surrounds a portion of an upper end of the post.
