Heavy hammer type wave power generation method and device

Disclosed are a heavy hammer type wave power generation method and device. According to the method and device, a rotating shaft (9) is arranged in the middle of a floating box (1), a vertical shifting rod (8) is connected to the rotating shaft (9), a heavy hammer (10) is fixed to the lower end of the shifting rod (8), a chain ring (6) meshed with a plurality of driving sprockets (4) and guiding sprockets (5) is fixedly connected to the upper end of the shifting rod, under the action of wave power and gravity, the floating box (1) enables the driving sprockets (4) and the guiding sprockets (5) to turn leftwards or rightwards along a chain, and, with the leftward or rightward turning of the driving sprockets (4), and by means of a speed-increasing gear (17) in a speed-increasing box and a transmission mechanism for converting bidirectional swinging to unidirectional rotation, a power generator shaft (IV) always rotates in one direction to generate power. According to the heavy hammer type wave power generation method and device, a wave energy collecting method is simple and easy, a large amount of wave energy can be collected, energy converting efficiency is high, the structure is simple, manufacturing costs are low, maintenance is avoided for a long time, service life is long, safety is good, a wave power generation station can be established by networking, and in comparison with a current wave power generation device, significant economic benefits and an extensive commercial application prospect are achieved.
