This invention discloses a dual-
buoy wave-current energy combined power generation device, comprising a connecting rod and two identical float power generation components. Each float power generation component includes a float upper shell, a support rod, a push rod, a
ratchet transmission
assembly, a speed-increasing
assembly, and a generator. The two float components are hinged together by the connecting rod and oscillate relative to each other with the
waves, using a lever principle to drive the push rod in a
reciprocating motion. The
ratchet transmission
assembly converts the
reciprocating motion into unidirectional rotational output, which is then accelerated by two stages of speed-increasing components to drive the generator, achieving dual-
buoy coupled power generation. The lower shell of the float is conical to reduce
seawater resistance and contains springs and vibration
energy storage blocks to recover
vibrational energy and improve wave energy utilization. This device uses a
helical impeller to absorb
ocean current energy; the blades are subjected to force perpendicular to the
helical shaft, achieving unidirectional self-starting rotation. This invention features a simple structure,
high transmission efficiency, and stable output. Through wave-current energy combined power generation and the dual-
buoy coupling design, it significantly improves power generation efficiency and device stability.
