The power generation device comprises a base, a floating thrust mechanism, a gear transmission mechanism and agenerator; the base is formed by a left base and a right base which are arranged in a mirror symmetry mode, a cavity is formed between the left base and the right base, and a left arc-shaped groove and a right arc-shaped groove which are vertical and correspond to each other are arranged between the left base and the right base; the two arc-shaped grooves are spliced into a motion space of the floating thrust mechanism, and the floating thrust mechanism drives a generator rotating shaft to rotate through the cooperation with the gear transmission mechanism; and the positions, away from the arc-shaped grooves, of the left base and the right base are provided with base plates, the gear transmission mechanisms are fixed on the base plate, and the isolation cover is arranged on the base platesin a cover mode. According to the power generation device, the isolation cover is additionally arranged, so that a gear transmission part in a power input mechanism is covered, direct contact betweenthe transmission part and seawater is effectively avoided, the situation that the transmission part is damaged due to seawater corrosion is effectively avoided, and the power generation device has outstanding practicability.
