The invention provides an
electromagnetic power generation and friction nanometer power generation composite wave energy conversion device, and relates to the field of wave energy utilization, the
electromagnetic power generation and friction nanometer power generation composite wave energy conversion device comprises an integrated power generation unit, the integrated power generation unit is formed by combining a plurality of power generation units, and each power generation unit comprises a square shell, a friction nanometer power generation part and an
electromagnetic power generation part; the
metal electrode clings to the inner wall of the square shell; a
magnet rotor is arranged in the square shell, and the
magnet rotor and a
copper electrode in the square shell form a friction nanometer power generation part; a plurality of
layers of coils are wound on the outer wall of the square shell, and the
magnet rotor and the coils form an electromagnetic power generation part. Wave energy is collected through friction nanometer power generation and electromagnetic power generation, the two power generation
modes are matched with each other, the available wave range can be effectively expanded, the conversion efficiency can be improved, the starting condition can be reduced, and therefore the device adapts to actual sea conditions with high randomness and time-varying characteristics.
