The application provides a wave energy power generation device and method for a sea surface unmanned vehicle. The wave energy power generation device is assembled in an axial direction by an end cover, a rectification filter
voltage stabilizer, a motor
stator, a composite rotor, a
magnetic modulation stator, a low-speed rotor and a base. Based on the
magnetic flux decoupling principle, the rotor of the slotless disc motor and the high-speed rotor of the axial
magnetic flux magnetic gear are combined into one body, which is used for realizing the
coupling of the structures of the two electromagnetic mechanisms and the decoupling of the
magnetic flux, ensuring that the magnetic circuits of the two electromagnetic mechanisms do not interfere with each other, and making the composed
magnetic gear composite motor have stable working performance. The application utilizes the speed increasing and step-out effect of the
magnetic gear, and under the driving of the built-in eccentric
pendulum, the high-efficiency wave energy power generation can be realized without direct contact with
seawater, and the application has the overload self-protection function, can provide long-term continuous power supply for the sea surface unmanned vehicle, has the advantages of firm structure, compact size and long service life, and has good practical value.
