Description
Technical field
The present invention relates to a kind of wind-driven generator.
Background technology
Wind-driven generator is that wind energy is converted into mechanical work, the rotation of mechanical work rotor driven, the electricity of final output alternating current
Power equipment.Existing wind-driven generator is mainly divided into two types, and a class is shaft resistance type windmill, and it is to utilize aerodynamic resistance
Power is done work, and shaft resistance type windmill also can easily start at low wind speeds, but its is less efficient；Another kind of is lift-type wind
Power machine, it is done work using the lift of aerofoil profile, lift-type fan efficiency it is high but its start under low gustiness it is extremely difficult, by
This, is badly in need of solving.
The content of the invention
It is an object of the invention in view of the above-mentioned problems, providing a kind of wind-driven generator, it can be under low gustiness
Start, and with good efficiency.
The purpose of the present invention is to be achieved through the following technical solutions：
A kind of wind-driven generator, including generator, resistance-type wind wheel and lifting wind wheel, the lifting wind wheel include rising
Power rotating shaft and the multiple lift force blades being installed in lift rotating shaft, the resistance-type wind wheel include resistance rotating shaft and are installed on resistance
The rotating shaft transmission of multiple resistance blades in rotating shaft, the lower end of the lift rotating shaft and generator is connected, and lift rotating shaft is upper
End is connected by freewheel clutch with resistance rotating shaft, the cross section of the resistance blade is D-shape configuration, and the lift force blade is indulged
Rectangular cross-section structure.
As a preferred embodiment of the present invention, described resistance blade is 4, is distributed uniformly and circumferentially.
As a preferred embodiment of the present invention, described lift force blade is 3, is distributed uniformly and circumferentially.
Beneficial effects of the present invention are, a kind of wind-driven generator not only efficiency high, and can starting at low wind speeds,
In addition, the structure by optimizing resistance blade, and then be able to can also start under extremely low wind speed, by optimizing lift force blade
Structure, substantially increases efficiency, simple in construction, be easily achieved.

Embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.It may be appreciated
It is that embodiment described herein is used only for explaining the present invention, rather than limitation of the invention.
It refer to shown in Fig. 1 and Fig. 2, in the present embodiment, a kind of wind-driven generator, including generator 1, resistance-type wind wheel
And lifting wind wheel, the lifting wind wheel includes lift rotating shaft 2 and 3 lift force blades 3 being installed in lift rotating shaft 2, institute
3 lift force blades 3 stated are along the circumferential direction uniform, and the resistance-type wind wheel includes resistance rotating shaft 4 and is installed on resistance rotating shaft 4
4 resistance blades 5, described 4 resistance blades 5 are along the circumferential direction uniform, lower end and the generator 1 of the lift rotating shaft 2
Rotating shaft transmission connection, and the upper end of lift rotating shaft 3 is connected by freewheel clutch 6 with resistance rotating shaft 4, the resistance blade 5
Cross section be D-shape configuration, the longitudinal section of the lift force blade 3 is rectangular configuration.
Low wind speeds, resistance-type wind wheel is first begin to rotate, and drives lifting wind wheel to rotate by freewheel clutch 6, enters
And drive the axis of rotation of generator 1；As wind speed gradually increases, lifting wind wheel rotating speed exceedes resistance-type wind wheel, now surpasses
More clutch 6 is played a role, it is ensured that resistance-type wind wheel and the coaxial friction speed of lifting wind wheel are rotated.
Above-mentioned a kind of wind-driven generator not only efficiency high, and can starting at low wind speeds, in addition, by optimizing resistance leaf
The structure of piece 5, and then be able to can also start under extremely low wind speed, by optimizing the structure of lift force blade 3, substantially increase effect
Rate, it is simple in construction, be easily achieved.
Above example is the general principle and characteristic for elaborating the present invention, and the present invention is not limited by above-described embodiment,
Without departing from the spirit and scope of the present invention, the present invention also has various change and change, and these changes and modifications all fall
Enter in scope of the claimed invention.The claimed scope of the invention is defined by the following claims.
