Abstract
Disclosed is a variable liquid column oscillator using wave energy in which an energy absorption mechanism of a wave energy apparatus tunes vibration characteristics responding to waves to a vibration cycle of waves to maximize energy absorption efficiency.
Claims5
A variable liquid column oscillator using wave energy comprising:
- a variable liquid column body having a U-shaped tube comprising a horizontal tube and vertical tubes communicating with each other through the horizontal tube, and air chambers connected to the vertical tubes, the air chambers being isolated from each other about an isolation plate;
- an air tube to connect the air chambers to each other;
- control valves mounted on the air tube;
- pressure transformers connected to the air chambers, respectively, and a level transformer connected to one of the vertical tubes;
- and
- a controller to which the control valves, the pressure transformers, and the level transformer are connected.
