Description
Technical field
The present invention relates to wind power generation field, more particularly to a kind of wind generator system.
Background technology
Wind-power electricity generation is that the kinetic energy kept watch switchs to electric energy.Wind energy as a kind of clean regenerative resource, increasingly by
The attention of countries in the world.Its amount of accumulateing is huge, and global wind energy is about 2.74 × 10^9MW, wherein available wind energy is 2 × 10^
7MW, the water energy total amount than that can be developed and used on the earth are also 10 times big.Wind is utilized by people very early -- mainly pass through windmill
Come draw water, flour milling etc., and present, interested people are how to use wind to generate electricity.
The required device of wind-power electricity generation, referred to as wind power generating set.Currently, common wind power generating set, generally
Wind wheel, generator and steel tower three parts can be divided.And wind wheel is the important component that the kinetic energy kept watch is changed into mechanical energy, traditional wind
Wheel is made of the impeller of two or more propeller shapes, when wind is to paddle, pneumatic power drive wind wheel is generated on blade and is turned
It is dynamic.And this wind wheel structure is when carrying out wind-power electricity generation, due to the architectural characteristic of paddle, only part to blow to paddle wind energy enough
Paddle rotation is blown, the utilization ratio of wind energy is relatively low.
Therefore, for above-mentioned phenomenon, a kind of model wind generating device is just referred in patent CN205503356U, is wrapped
A shell is included, the shell is hollow-core construction, has an air inlet and an air outlet；One rotary shaft, the rotary shaft peace
In shell, and one end of rotary shaft is stretched out outside shell, and the both ends of the rotary shaft are mounted on by bearing and bearing block
On shell；One rotating mechanism, the rotating mechanism is arranged in shell, by several equally distributed along rotary shaft circumferencial direction
Rotating blading collectively constitutes, and the rotating blading is rectangular, and one end of rotating blading is mutually fixed with rotary shaft.The present invention's
Advantage is：Model wind generating device in the present invention is improved by the structure to conventional wind wheel, using shell, rotation
Shaft and the matched design of rotating blading, not only facilitate the acquisition of wind, while can effectively improve the utilization rate of wind energy.
In above structure, find to remain certain defect during use：External wind from shell into
Air port is into when blowing to rotating blading, and since rotating blading is a tablet, and rotating blading is when rotated, when rotating blading revolves
After turning over air inlet, external wind has part wind when blowing to rotating blading and scatters and disappears from the side of rotating blading, reduces the external world
The utilization rate of wind.
