Embodiment 1

[0071] A wave energy generating device utilizing a spiral structure, comprising a wave energy collector, a bracket connected to the wave energy collector, a wave energy conversion main mechanism arranged inside the wave energy collector, an energy transmission device and an energy output device;

[0072] The wave energy collector includes a cavity and a cam body arranged outside the cavity, and the cavity is a cylindrical cavity;

[0073] The main mechanism of wave energy conversion is located in the cylindrical cavity. The main mechanism of wave energy conversion is provided with a fixed shaft. The main mechanism of wave energy conversion includes a screw turntable, a piston rod group, and a hydraulic cylinder. The hydraulic cylinder is connected with the fixed shaft. The bracket bolt group is connected with the bracket, the screw turntable is connected with the piston rod group, the piston rod group is connected with the hydraulic cylinder, and the screw turntable is connecte...

Embodiment 2

[0078] A wave energy power generation device using a spiral structure, the structure is as described in Embodiment 1, the difference is that the cam body of the wave energy harvester is provided with ups and downs and floating holes. Floating bodies such as foam plastics can be added to the heave and float holes, so that the heave and float holes will heave up and down with the heave motion of the wave, which is specifically manifested as the swing of the wave energy harvester around the fixed axis, so that the wave energy harvester can control the wave's rise and fall. The potential energy of the sinking motion is transformed into the mechanical energy of its own swing. In addition, the kinetic energy of the wave impact movement captured by the wave energy harvester makes the wave energy harvester have a higher wave energy capture capability.

Embodiment 3

[0080] A wave energy generating device using a spiral structure, the structure is as described in Embodiment 1, the difference is that the wave energy generating device utilizing a spiral structure also includes a support baffle, and the support baffle is arranged outside the main wave energy conversion mechanism At both ends, the wave energy conversion main mechanism is bolted to the wave energy harvester through the support baffle, and the support baffle is connected to the fixed shaft through the bearing. The support baffle is located at the outermost side of the main wave energy conversion mechanism, and is fixedly connected to the wave energy harvester through the support baffle bolt group to play the role of support and sealing, and at the same time swings with the swing of the wave energy harvester.
