Central float type wave energy power generation device

Abstract

The invention relates to a central float type wave energy power generation device which is used for power generation of wave energy and belongs to the technical field of ocean energy utilization. The central float type wave energy power generation device structurally comprises a big central float body, connection bodies, and a plurality of independent oscillation type wave energy converting devices which are distributed around the big central float body, wherein the oscillation type wave energy converting devices are connected with the big central float body through connection rods and connection bodies. The big central float body of the power generation device does heaving movement in wave; the plurality of independent oscillation type wave energy converting devices around the big central float body are similar to a traditional wave energy absorption device and can independently absorb and convert the wave energy. When the heaving natural frequency of the big central float body is equal or close to the movement frequency of the wave, the big central float body and ocean water resonate, then the wave drives the big central float body to move violently, the oscillation of the big central float body is transferred to each wave energy converting device through the connection rods, and the oscillation movement is amplified; and the central float type wave energy power generation device has a high absorption rate, a high conversion rate and high impact resistance.

Description

technical field [0001] The invention relates to a wave energy generating device, in particular to a central float type wave energy generating device, which belongs to the field of ocean energy utilization. Background technique [0002] Ocean energy refers to the energy obtained from the ocean. Today, the ocean covers about 70% of the earth's surface, and the ocean has become the world's largest solar collector and energy storage system. Theoretically, 600,000 square kilometers of tropical ocean absorbs solar radiation every day, which is equivalent to the energy contained in 25 billion barrels of oil. Among all ocean energies, wave energy has the highest energy density, has little impact on the environment during development, and exists in the form of mechanical energy. Therefore, wave energy is the most ideal and most worthwhile ocean energy. [0003] Because wave energy has high energy density, wide distribution, and is an inexhaustible renewable clean energy, in the wav...
