A wave energy power generation device utilizing high-pressure airflow to transfer energy belongs to the field of wave energy power generation technology. To address the common problem of insufficient inlet pressure in wave energy power generation devices under conditions of small waves and gentle water flow, the invention includes a fixed structure. The inner wall of the fixed structure is threaded with a fastening structure, and the inner cavity of the fixed structure is rotatably connected to a power generation structure. A water flow detector is fixedly installed on the inner wall of the fixed structure. This invention uses a swinging structure composed of torsion springs and wave-beating plates on both sides of the water inlet chamber. After the waves recede, the torsion springs drive the swinging plates to quickly return to their original position, creating periodic water level fluctuations in the inlet area. This transforms the stable, continuous water flow into a pulsating, impacting water flow. This pulsating characteristic better matches the working characteristics of an air turbine, making the high-pressure airflow output more regular. This effectively improves the shortcomings of existing wave energy devices, such as large power generation fluctuations and low efficiency under low wave conditions, thus enhancing the overall power generation performance of the device.
