Technical Field

[0002] Wind power generation refers to the conversion of wind kinetic energy into electrical energy. As a renewable and clean energy source, wind energy has huge reserves and high utilization value, and therefore has been rapidly developed. This requires the use of wind power generation equipment, which mainly includes wind rotors, generators, towers, direction regulators, speed limit safety mechanisms and energy storage devices. Among them, generators are mainly divided into two types: horizontal axis wind turbines and vertical axis wind turbines. Since the rotor rotation axis of the vertical axis wind turbine is perpendicular to the ground or the direction of airflow, the vertical axis wind turbine plus the windward plate structure has effectively solved the wind power problem in inland urban areas when the wind is weak or even in a breeze, and improved the efficiency of urban wind energy utilization. However, in the above structure, when the wind direction changes, the power generation capacity of the wind turbine will be affected to a certain extent, and the wind energy cannot be utilized to the maximum extent.

[0003] A Chinese patent discloses a vertical axis wind turbine with an inclined brace (authorization announcement number CN213743823U). The patented technology is provided with a first inclined brace, a spiral airfoil blade and a second inclined brace. Various wind directions can drive the vertical axis wind turbine to generate electricity, and the thrust on the spiral airfoil blade will not be reduced due to different wind directions, thereby ensuring the power generation efficiency of the wind. By providing a first inclined brace and a second inclined brace, the first inclined brace and the second inclined brace are respectively inclined downward and upward, and the spiral airfoil blade is supported by the first inclined brace and the second inclined brace, thereby improving the stability of the spiral airfoil blade, but the entire blade is exposed to the outside, and the wind energy cannot be utilized to the maximum extent, resulting in low power generation efficiency.
