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.

The present invention discloses a multi-layer staggered φ-type wind turbine blade structure, which includes a wind turbine shaft and several layers of curved blade groups with wing-shaped cross sections. The several layers of curved blade groups are fixed on the wind turbine shaft in an inner and outer layered manner. Each layer of curved blade group includes several curved blades, and the curved blades are all φ-type wind turbine blades with upper and lower ends fixed to the wind turbine shaft and the middle part bent outward. The inner layer of curved blades and the outer layer of curved blades are staggered at a certain angle and arranged circumferentially around the wind turbine shaft. The present invention can effectively improve the wind capture capability, thereby improving the self-starting performance. The positions where the wind turbine blade structures of each layer are fixed to the wind turbine shaft are also symmetrically distributed, which can enhance the integrity of the structure, improve the buckling stability of the wind turbine shaft, and improve the utilization rate of wind energy. The curved blades are fixed to the wind turbine shaft through bolt sleeves, so that the installation and removal of the inner layer of wind turbine blades are simple and easy to maintain.
