Marine floating body, marine floating body array with wave-breaking baffle, and wind-wave resisting method using the same

Abstract

A marine floating body is provided with an air chamber, and is configured to float on a sea surface. A wall structure enclosing the air chamber includes a top wall and a side wall. The top wall is fixedly provided with a photovoltaic assembly. The side wall is provided with an inlet check valve. The marine floating body is configured to submerge under large waves to avoid impact and to resurface automatically when conditions calm. A redundant buoyancy of the marine floating body array is controlled so that, under extreme weather, a wind pressure generated by large waves exceeds the buoyancy, causing the array to submerge, and the array resurfaces when the wind and waves diminish. A marine floating body array with a wave-breaking baffle, and a wind-wave resisting method using the same are also provided.
