摘要： The present disclosure relates to the technical field of ocean energy resources, and specifically, to an ocean wave power generation apparatus using a high-pressure airflow for energy transfer. The apparatus includes a power generation workbench, where an electric power storage apparatus is installed at one end of the power generation workbench, the electric power storage apparatus is connected to a turbine generator, the turbine generator is installed on the power generation workbench, and an air tank is disposed on the left side of the turbine generator, securely installed on the power generation workbench, and connected to the turbine generator through an air outlet pipe. The apparatus drives, by using a fluctuation force of an ocean wave, a piston to reciprocate to compress air into an air treatment apparatus for storage. When the air treatment apparatus reaches a rated pressure, air is released through an air outlet valve, and an air output is controlled by a pressure limiting valve and a spherical valve, to generate a stable high-pressure airflow to drive the turbine generator to operate, thereby realizing voltage-stabilized power generation and improving power generation efliciency.
