Multifunctional buoy based on multisource energy supply coupled self power generation

The invention discloses a multifunctional buoy based on multisource energy supply coupled self power generation. The buoy comprises a solar power generation device, a magnetic suspension power supplybirotor combining wind energy and water energy and a floater type wave energy power supply device which drives a rotor to move by means of an up-and-down motion of a float along with waves, so that agenerator outputs alternating current. Abundant solar energy, wind energy, water energy and wave energy on the water surface can be utilized fully, and natural energy sources and marine tide resourcesare recycled to the maximum extent, thereby providing enough electric energy for the buoy. The buoy structure designed according to the demand of multisource power supply equipment not only can meetthe demands on different power generation equipment, but also can reduce the damage caused by collision of ships, seawater corrosion and typhoon invasion effectively, thereby providing accurate and reliable data for marine scien
