[0002] With the shortage of energy, wind energy as a renewable energy source and wind power generation as a pollution-free renewable energy source have attracted much attention. As a result, wind power generation equipment has developed rapidly and the demand for wind power generation equipment has increased dramatically. At present, in order to start at low wind speed, the vertical axis wind turbine has a starting duct and the blades are all on the upper part of the wind turbine. In this way, the torque on the wind turbine shaft is large, the overall structural strength needs to be strengthened, and the cost increases and the volume increases accordingly. Another solution is to assemble the blades symmetrically up and down without a starting duct, so that the starting wind speed of the wind turbine will be increased. Therefore, a vertical axis wind turbine structure with high reliability is proposed. Summary of the Invention
