The invention provides a device for power generation through a Karman vortex street. The device comprises a windward barrel body, a rotation shaft, a power generator stator, a power generator rotor, asupport, an enlarging plate, a top cover, a base and a power transmission hole. The rotation shaft is arranged in the windward barrel body. The windward barrel body is provided with three parts, thefirst part and the third part are fixedly connected with the rotation shaft and the enlarging plate, the second part is fixedly connected with the base through the support, the power generator rotor is fixedly arranged on the rotation shaft, and the power generator stator is fixed to the inner wall of the second part of the windward barrel body. The top cover is arranged at the upper portion of the windward barrel body, the base is arranged at the lower portion of the windward barrel body, and the power transmission hole is formed in the second part of the windward barrel body. The device hasthe beneficial effects of being simple in structure, convenient to manufacture, small in occupied space and the like, and the device can be more conveniently applied to multiple environments for powergeneration. The device can automatically adjust the work state so as to adapt to different wind directions.
Description
technical field [0001] The invention relates to a device for generating electricity, in particular to a device for generating electricity by using a Karman vortex street. Background technique [0002] With the progress and development of society, the development and utilization of renewable energy has become an issue of increasing concern. Among them, wind energy, as the first renewable resource utilized by people, has received attention from all over the world. Traditional wind generators still rely on the wind to drive the blades to rotate, and then increase the speed through the speed-increasing mechanism, thereby driving the generator to rotate and realize power generation. However, this kind of large-scale wind turbine will not only cause a series of inconveniences in maintenance because the wind tower is too high, but also the blades will generate a lot of noise while rotating, and at the same time pose a threat to passing birds. In order to solve these problems and ...
