A wind turbine in the shape of a harp

Abstract

The invention discloses a harp shaped wind-driven generator. The harp shaped wind-driven generator comprises a vertical shaft and at least one semicircular blade, wherein the lower end of the verticalshaft is rotatably connected to a base; the blade can rotate around an axis of the vertical shaft; the blade comprises a plurality of blocks which sleeve a rope; two ends of the rope are correspondingly connected to connecting ports which are formed in two ends of the vertical shaft; every two adjacent blocks are connected through an elastic deformation module. The harp shaped wind-driven generator further comprises a plurality of elastic chord sets; each elastic chord set comprises a first elastic chord and a second elastic chord which are parallel to the axis of the vertical shaft; two endsof the first elastic chords and the second elastic chords are correspondingly connected to the corresponding blocks. The harp shaped wind-driven generator is simple in structure, and easy to manufacture; all parts can be combined or bent; the wind energy utilization rate is high; the applicable scope is wide; and the harp shaped wind-driven generator is applicable to large wind power stations orsmall portable wind power 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
