The energy, is likely to become important alternative energy source in long term.Same level axis wind power generator is compared, vertically
Axis wind power generator has wind energy utilization high, and pneumatic wind speed is low, the advantages of do not produce noise substantially,
Through gradually recognized and attention, with extensive market application foreground.Existing vertical wind power generation
Machine can be divided into two main Types, and a class is that typical structure is S using aerodynamical resistance market
Type wind wheel；Another kind of done work using the lift of aerofoil profile, most typically the Darrieus.Lift
But the high low wind speed difficulty in starting of type fan efficiency, and the low wind speed of resistance-type blower fan easily starts but fan efficiency
Low, therefore, existing vertical axis aerogenerator also has the following disadvantages：When the 1st, generating electricity, need sufficiently large
Wind-force wind wheel could rotate；2nd, in the presence of a harsh environment, the tolerance of wind wheel is weak, and service life is short, dimension
Repair high cost.
Content of the invention
The purpose of the present invention is：Overcome deficiency of the prior art, there is provided a kind of reasonable in design, make
With the combined wind turbine structure in the wind-driven generator of life-span length using freewheel clutch transmitting torque.
For solving above-mentioned technical problem, the technical solution used in the present invention is as follows：
In a kind of wind-driven generator using freewheel clutch transmitting torque wind wheel structure, including H type fan blades
With S type fan blades, on H type fan blade mandrels, the S types fan blade is arranged on S to the H types fan blade
On type fan blade mandrel, the S types fan blade is located at the inside of H type fan blades, and the S types fan blade mandrel passes through
Bearing and freewheel clutch are connected with H type fan blade mandrels.
Further, there is flange on the H types fan blade mandrel, the H types fan blade is by H types fan blade
Frame and bolt washer are fixed on flange.
Further, the H types blade support has upper and lower two, and the H types blade support includes some
Cross bar, the cross bar are bolted on the flange of H type fan blade mandrels, and the cross bar passes through bolt
It is connected with brace, the cross bar, brace are connected with H type fan blades by bolt.
Further, a circular frame is provided with by bolt between the cross bar, cross bar is circumferentially
It is uniformly distributed.
Further, the S types fan blade is by S type fan blade anchor ears and screw gasket and S type fan blade mandrels
Connection.
Using the beneficial effect of technical scheme it is：
1st, H types fan blade and S type fan blades are applied in combination in the present invention, when H types wind speed round is less than S
During type, S types wind wheel can provide extra torque power for H type wind wheels, be particularly suitable for opening for H type wind wheels
Dynamic；When H types wind speed round is higher than S types, can be automatically-unhooked between mandrel, do not interfere with H type wind wheels
's.This kind of structure mainly overcomes that the low wind speed startability of H type blower fans is poor, improve low wind by combinative structure
Startability in the case of speed, substantially improves the power generation performance of blower fan under low wind speed.
2nd, on the one hand the cross bar on medium-height trestle of the present invention supports fan blade, and on the other hand protection fan blade is in regulation
It is not broken in wind ranges, extends the service life of fan blade, reduces maintenance cost；Install on cross bar
Circular frame, mainly adjusts the stability in the large of cross bar, strengthens the bending resistance of cross bar, reduction fan blade and shakes
Dynamic, extend the service life of fan blade.
