A wind turbine in the shape of a harp

Abstract

The invention discloses a harp-shaped wind turbine, which includes a vertical shaft and at least one semicircular blade; the lower end of the vertical shaft is rotatably connected to a base; the blade can rotate around the axis of the vertical shaft, so The blades include a plurality of modules that are sleeved on a rope, and the two ends of the rope are respectively connected to the connection ports at both ends of the vertical axis. The adjacent modules are connected through elastic deformation modules. The harp-shaped wind turbine further includes a plurality of elastic string groups, the elastic string group includes a first elastic string and a second elastic string parallel to the axis of the vertical shaft, the first elastic string and the second elastic string Both ends of the elastic string are respectively connected to the corresponding modules. The invention has a simple structure and is easy to manufacture. Each component can be combined or bent. It has high wind energy utilization rate and wide usage scenarios. It can be used in large wind power stations or small portable wind generators.

Description

technical field [0001] The patent of the present invention belongs to the technical field of wind energy utilization, and in particular relates to a harp-shaped wind power generator. Background technique [0002] Wind energy is abundant, nearly endless, widely distributed, clean and moderates the greenhouse effect. In today's world where energy resources are increasingly tense and the environment is deteriorating, the importance of wind energy utilization has become increasingly prominent. Fan is a device that uses wind energy to obtain electric energy. It has the advantages of economy, cleanliness, pollution-free and energy saving, and has been developed and utilized by people for a long time. [0003] However, in the existing wind turbines, the cut-in wind speed is usually required to be relatively high. When the wind force is weak, it cannot generate electricity, resulting in the instability of wind power generation; the ability to resist typhoons is weak, and it is easy...

Problems solved by technology

[0003] However, in the existing wind turbines, the cut-in wind speed is usually required to be relatively high. When the wind force is weak, it cannot generate electricity, resulting in the instability of wind power generation; the ability to resist typhoons is weak, and it is easy to be damaged when a strong typhoon blows past; The generator also has defects such as high cost and narrow application range
