Background

Ocean wave (ocean wave) generally refers to waves in the ocean that are generated by wind. Mainly comprises stormy waves, surging waves and ocean inshore waves. Under different wind speeds, wind directions and terrains, the dimensional change of sea waves is quite large, the period is usually a few tenths of a second to tens of seconds, the wavelength is a few tens of centimeters to hundreds of meters, the wave height is a few centimeters to 20 meters, and under rare terrains, the wave height can reach more than 30 meters. Sea wave is a wave formed by the fact that sea surface relief forms spread, and water particles leave an equilibrium position to vibrate periodically and spread in a certain direction. The vibration energy of the water particles forms kinetic energy, the wave fluctuation energy generates potential energy, and the cumulative amount of the two energies is striking. In the global ocean, only the total energy of storms and swells is equivalent to half of the solar energy reaching the outside of the earth. The energy of the ocean wave rolls forward in the direction of ocean wave propagation. Thus, the sea wave is in fact a wave-shaped propagation of energy. The wave period is from a few tenths of a second to more than a few hours, the wave height is from a few millimeters to tens of meters, and the wavelength is from a few millimeters to thousands of kilometers.

With the increasing shortage of energy, the demand of human beings for energy is increasing, and research and development and utilization of new energy are imperative. Ocean energy is inexhaustible pollution-free energy, china is a large ocean country, available ocean wave energy is extremely abundant, and coastal ocean energy is high in reserve. The sea wave can continuously rise and fall within 24 hours a day, is inexhaustible energy, belongs to a green environment-friendly project, and has great development and utilization values. Therefore, there is a need for a power generation facility capable of generating power using ocean waves.
