Description

technical field [0001] The invention relates to the technical field of tidal energy utilization, in particular to a near-shore wave energy and tidal energy combined power generation device. Background technique [0002] my country has a coastline of nearly 20,000 kilometers, which is rich in marine kinetic energy. Using marine kinetic energy for comprehensive power generation is safe, reliable, clean, and inexhaustible. Ocean kinetic energy can generally be divided into three types: tidal energy, wave energy, and ocean current energy. Among them, tidal energy is regular, while wave energy is irregular. The kinetic energy reserves of my country's coastal oceans are about 190 million kilowatts of tidal energy, and 10-20 kilowatts of wave energy per square kilometer. Among them, the annual average wave height is 2 meters, and the wave with a wavelength of 1 meter takes about 6,000 hours. Its energy is considerable. In order to take advantage of this huge ocean kinetic energ...
