Description

technical field [0001] The invention relates to a wave turbine type double-action pressurized power generation device, which belongs to the research field of marine renewable energy utilization. Background technique [0002] With the rapid development of the human economy, along with the excessive development and utilization of traditional non-renewable fossil energy, the energy crisis is becoming more and more serious, and the energy supply situation in my country is even more tense. According to statistics, my country's energy production is 13.2×10 8 t standard coal, the consumption is 13.9×10 8 t standard coal. Among them, coal accounts for 75%, oil accounts for 17%, natural gas accounts for 2%, hydropower and nuclear power account for 6%, and the main energy also strongly relies on burning fossil fuels. Therefore, it is very necessary to find a renewable and alternative clean energy. [0003] Ocean energy, as a renewable natural energy, mainly includes tidal energy, ti...
