8. wind power driving system according to claim 2, it is characterised in that: the blade is compound by light-alloy and carbon fiber
It forms.
9. wind power driving system according to claim 2, it is characterised in that: the blade mechanism includes the upper of suspension wind wheel
The lower beam of crossbeam and suspension wind wheel, multiple groups blade mechanism are connected between upper beam and lower beam.
10. wind power driving system according to claim 1, it is characterised in that:, should when the fan blade is located at upwind position
Position two halves leaf blade is open maximum wind wheel rotation work power generation windward；When the fan blade is located at leeward position, fan blade is opened
Mouth, which becomes smaller, reduces blade front face area, and wind wheel revolution working resistance is made to become smaller.
