Description of the Invention: [Technical Field] The present invention relates to a power generating device, and more particularly to a power generating device capable of welcoming a current flow. [Prior Art] As the Earth's sources are diminishing and global warming problems are becoming more and more serious, 'in addition to efforts to reduce energy consumption and reduce carbon emissions, countries are actively developing or seeking clean alternative energy sources, such as More common solar power and wind power. However, the ocean accounts for 70% of the total area of the earth, and Taiwan is an island country surrounded by the sea. Therefore, in addition to the application and development of solar power and wind power, it has also begun to develop toward ocean power generation in recent years. The most common type of ocean power generation is Temperature difference power generation, wave power generation, tidal sofa power and tidal power generation. The thermoelectric power generation uses the temperature difference between the surface seawater and the deep seawater to generate electricity; the wave and tidal power generation converts the kinetic energy of the wave into electrical energy for power generation; the tidal sofa electricity uses the potential energy difference between the high tide and the low tide to generate electricity. Among them, 'temperature difference power generation is stable but power generation efficiency is poor; while wave power generation is limited by the weather factor is relatively unstable; in addition, the height difference between high tide and low tide in Taiwan sea area is only three to four meters is not conducive to tidal power generation; The power generation and stability of tidal power generation are better than the above-mentioned methods. Moreover, there are black tides in the eastern part of the Taiwan Strait in the western part of Taiwan. For Taiwan, it is a knives suitable for the use of kinetic energy for power generation. However, the biggest impact of tidal power generation is that the trend will change the flow with the season, which will affect the efficiency of tidal current generation. Therefore, how to make the tidal current generating set meet the maximum tidal current velocity and obtain stable power generation efficiency. The most difficult problem to overcome when applying tidal power generation.
