When the power generation device of the embodiment is placed in the sea, the floating body 7 drives the power generation device to float on the sea surface, so that the wind wheel 1 is positioned on the sea surface, and the water wheel 2 extends into the sea water. In the embodiment, the wind wheel 1 and the first mounting plate 5 are connected through the first rotating shaft 3, the water wheel 2 and the second mounting plate 6 are connected through the second rotating shaft 4, and when sea wind drives the wind wheel 1 to rotate and further drives the first mounting plate 5 to rotate, the first dielectric diaphragm 9 connected to the bottom surface of the first mounting plate 5 can be contacted with and separated from the first friction plate 8, so that power generation is realized; when the ocean current impacts the water wheel 2, the water wheel 2 is driven to rotate, the second mounting plate 6 is further driven to rotate, and the second dielectric diaphragm 10 connected to the top surface of the second mounting plate 6 can be in contact with and separated from the first friction plate 8, so that power generation is realized.
