The invention belongs to the technical field of industry. An airfoil wind-driven generator based on a simple pendulum comprises an airfoil blade, an airfoil blade pitch control device, a generator cabin, a base rod, a grounded base, a simple pendulum weight, a simple pendulum rod, a generator drive shaft and an airfoil support shaft, wherein the simple pendulum rod and the airfoil support shaft are fixedly connected together with the generator drive shaft separately; the generator drive shaft is fixedly connected together with the generator in the generator cabin; the generator cabin is fixedto the base rod; the base rod is fixed to the grounded base; the simple pendulum weight is fixedly connected together with the simple pendulum rod; and the airfoil blade is controlled through the airfoil blade pitch control device to rotate by a certain angle around the airfoil support shaft, and the airfoil blade pitch control device controls the airfoil blade to rotate to change an incidence angle. According to the airfoil wind-driven generator based on the simple pendulum, low-wind-speed wind energy is stored by virtue of the simple pendulum, the generator is driven to generate power through resonance, and the invariable frequency of the wind-driven generator is kept by virtue of the low-wind-speed energy. Moreover, high adaption capacity to a high wind speed is achieved, and the bladeis not liable to be damaged in the case of the high wind speed.
Description
technical field [0001] The invention belongs to the technical field of industry and relates to a novel wind power generation method using an airfoil, in particular to a power generation method utilizing the resonance principle of a single pendulum. Background technique [0002] At present, ordinary wind turbines are composed of several important parts such as generators, wheel blades, nacelles, transmission shafts, and tail rudders. This kind of wind generator has high requirements on wind speed, and must be higher than a certain wind speed to work. The frequency of electric energy produced by ordinary generators is uncertain, and the cost of converting it into usable alternating current is relatively high. Moreover, ordinary wind turbines are difficult to adjust, so the damage rate of the wheel blades is extremely high, resulting in extremely high maintenance costs. Contents of the invention [0003] The technical problems to be solved by the present invention are: to ov...
