A wave energy power generation device includes a plurality of up-down moving mechanisms configured to move up and down along a spiral rod under the action of waves, a mass block arranged at a lower part of the power generation device; a buoyancy barrel arranged in the middle of the power generation device, a guide rail arranged on one side of the up-down moving mechanism, and a spiral rod. Through the interaction of the up-down moving mechanism and the spiral rod, the up-down movement of waves can be converted into rotational kinetic energy, a scroll spring is used for storing energy, then the rotating speed is stabilized through an escapement mechanism, a power generation assembly accelerates energy output, and finally a generator is driven to generate power.
