The invention belongs to the field of tidal current energy generation, and in particular relates to a tidal current energy conversion device for comprehensively utilizing linear rotary power generation. The invention combines the design of the hydraulic generator and the linear generator, so that the overall energy capture efficiency of the power generation device is greatly improved, the kinetic energy of the remaining water flow in the power generation part of the hydraulic turbine is fully utilized, and the transportation efficiency is improved. The present invention adopts the design of double water turbines, and the left, right, front and rear asymmetrical design ensures that the tidal current energy can be fully converted, while making the overall structure more compact and reducing the volume of the device, so that more tidal current energy conversion can be arranged in a unit sea area area device to get more power. The invention has good energy capture efficiency, and the compactness and volume of the power generation device are more advantageous than the existing tidal current energy power generation device, and has broad development prospects and promotion prospects.
Description
technical field [0001] The invention belongs to the field of tidal current energy generation, and in particular relates to a tidal current energy conversion device for comprehensively utilizing linear rotary power generation. Background technique [0002] With the increasing human demand for resources, the consumption of non-renewable resources such as oil, coal, and natural gas is accelerating. For the sustainable development of human beings, the research and utilization of renewable resources is imminent. Ocean energy has the highest energy density in the field of renewable energy, including wave energy, tidal energy, ocean current energy, seawater temperature difference energy, seawater salinity difference energy, etc. Technological progress has also made the use of ocean energy possible. [0003] Among them, tidal current energy, as a kind of ocean energy, has a huge advantage in utilization. Tidal current energy mainly refers to the relatively stable flow in submarine...
