Description

technical field [0001] The invention relates to the technical field of marine renewable energy utilization, in particular to a floating and oscillating water column type wave energy generating device which utilizes an air accumulator to realize stable power generation. Background technique [0002] The ocean, which accounts for about 71% of the earth's surface, not only contains rich biological resources, but also a huge treasure house of energy. Ocean wave energy is a renewable energy attached to the surface of seawater, and it is the kinetic energy and potential energy of surface waves. Wave energy is a clean and renewable energy with abundant reserves, wide distribution, and easy large-scale development and utilization. However, due to the harsh marine environment and the instability and inconcentration of wave energy, wave energy power generation is unstable, the conversion efficiency is low, and the utilization cost is high. [0003] There are many types of wave energ...
