| 摘要 |
The present invention utilises the effect of the swaying back and forth of a partially submerged object in response to wave motions in an ocean area. A drift surface at one end of a shaft aligns a partially submerged wave power plant with a wave direction whilst a propeller-like device at the other end of the shaft converts the motions into rotation of the propeller which in turn is converted into energy, for example, electrical energy. The distance between the drift surface and the propeller-like device is equal to or approximately equal to a half wavelength identified as a statically predominant wavelength in the ocean area in which the wave power plant is located. |
