Background technique

With the depletion of global chemical energy, wind power, as a clean and pollution-free renewable energy, may become an important alternative energy in the long run. Compared with horizontal-axis wind turbines, vertical-axis wind turbines have the advantages of no wind setting, high wind energy utilization rate, low aerodynamic wind speed, and basically no noise. They have gradually been recognized and valued by people, and have broad market application prospects. .

Existing vertical axis wind turbines have complex structures, heavy weights, and large dimensions. On the one hand, they are inconvenient to pack, transport and carry. On the other hand, they cannot be installed for power generation anytime and anywhere. Therefore, fans with only lift-type blades must be equipped with manual start-up devices. When the wind is unstable, it is necessary to start the fan frequently, which makes the operation very inconvenient. Therefore, its application is greatly restricted in occasions that require power generation, such as home travel and outdoor camping.
