Problems solved by technology

[0003] There are also some researches on wind turbines with arc-shaped wind blades. They are called ice fans in the industry. They are characterized by being very easy to miniaturize and have a high utilization rate of wind resources. The destructive power of the components is very large, so how to reduce the speed of them when the wind is strong becomes the content that needs to be paid attention to. If the problem of reasonable speed reduction cannot be solved well, it will seriously hinder the wind turbine with curved wind blades. development of

Abstract

The invention relates to a light wind power generation device which comprises a frame structure, a rotating blade device and a power generation set. Through the improvement on arc-shaped wind power blades in a rotating blade device, a wind power utilization ratio is raised substantially, and through stopping sheets which are made of appropriate materials and arranged in appropriate positions of the arc-shaped wind power blades at appropriates angles, the speed can be reduced reasonably when wind is strong, so that the durability and the stability of the light wind power generation device are improved, and the popularization of the light wind power generation device is facilitated more.

Description

technical field [0001] The invention belongs to the field of wind power generation and materials, in particular to a light wind power generation device. Background technique [0002] The current wind turbines are mainly installed at the western tuyeres or on the sea, which have extremely high requirements on the material of the blades, and also have very high requirements on the contact parts such as bearings. This is because many existing wind turbines do not have wind speed limiting devices, that is, It is said that when the wind is very strong, the wind turbine blades rotate at a high speed for a long time, which will wear out the contact parts such as bearings. Even if there is a wind speed limiting device, the purpose of speed limitation is achieved by reducing the speed of the rotating shaft, which only adds a lot of other wearing parts. [0003] There are also some researches on wind turbines with arc-shaped wind blades. They are called ice fans in the industry. They...
