Title:
METHOD FOR ENHANCING WAVE ENERGY OF FLOATING BODY
Document Type and Number:
WIPO Patent Application WO/2021/098413
Kind Code:
A1
Abstract:
A method for enhancing wave energy of a floating body. The method for enhancing wave energy comprises a buoyant force enhancement method and/or a gravity force enhancement method. The buoyant force enhancement method comprises: when a buoy reaches a wave trough balance position, pressing, by means of an external force, all the hollow part of the upper part of the buoy to be below a water surface line; and when a next wave peak reaches, an entire buoy is located below a wave peak water surface, and the buoyant force is maximum, then releasing the buoy, centrally obtaining a force for working, and making the buoyant force of the buoy act on the outside until the buoy rises to a wave peak balance position. The gravity force enhancement method comprises: after the buoy reaches the wave peak balance position, raising, by means of an external force, all the water-containing part of the lower part of the buoy to be above the water surface line; and when a next wave trough reaches, the entire buoy is above a wave trough wave surface, and the gravity force is maximum, then releasing the buoy, centrally obtaining a force for working, and making the gravity force of the buoy act on the outside for working until the buoy returns to the wave trough balance position. Therefore, when a wave height is obviously lower than the designed nominal wave height of the buoy of a wave-energy power generation apparatus, the present invention can improve the efficiency of the wave-energy power generation apparatus.
