Technical Field

[0001] The utility model relates to a wind power generator, in particular to a vertical axis wind power generator, belonging to the technical field of generators. Background Art

[0002] A generator is a mechanical device that converts mechanical energy into electrical energy. It is driven by a turbine, steam turbine, diesel engine or other power machinery, and converts the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and transmits it to the generator, which then converts it into electrical energy. There are many forms of generators, but their working principles are all based on the law of electromagnetic induction and the law of electromagnetic force.

[0003] The patent application CN219159103U discloses a support structure for a vertical axis wind turbine, which relates to the technical field of vertical axis wind turbines, including a tower, a vertical axis and a wind turbine, wherein the wind turbine includes a plurality of arm beams and a plurality of blades, and a support assembly is provided at a position where the vertical axis is higher than the tower; both sides of the support beam are provided with placement grooves that are open and upward and inclined relative to the horizontal plane, and a slide and an anti-slip structure that prevents the slide from escaping from the placement groove are provided in the placement groove. When the wind turbine rotates, the slide in the support structure of the present application slides outward through the opening, thereby providing auxiliary support for the wind turbine, enhancing the support effect of the support assembly, and further improving the wind resistance of the vertical axis wind turbine, creatively improving the problem that traditional vertical axis wind power generation equipment is difficult to achieve large-scale.

[0004] Since vertical axis wind turbines are widely used due to their simple structure and non-directionality, the device in the above patent improves the fixing ability of the wind turbine. However, when the vertical axis wind turbine encounters strong winds, its speed control is difficult and the internal motor and fan blades are easily damaged. Therefore, we provide a vertical axis wind turbine to solve the above problems. Utility Model Content
