Description
Technical field
The present invention relates to a kind of vertical axis windmill, especially a kind of afflux vane group distribution type centre of gravity is efficient
Vertical axis windmill, belongs to technical field of wind power generating equipment.
Background technology
According to the applicant understood, in the wind power generating set run in the market, wind energy conversion system used is the most most
Number is the horizontal axis turbines formula wind energy conversion system of wind wheel rotating shaft horizontal positioned, belongs to high wind speed wind energy conversion system category, its
In low wind speed poor performance, at average annual wind speedThe regional economical operation bad economic results of meter per second.Additionally,
This kind of wind energy conversion system operation noise is big, can produce infrasonic wave, is not suitable for using in city and community, and
Also can endanger the living environment of birds.
Additionally, also vertical axis windmill, the feature of this type of wind energy conversion system is that calm tropism requires, noise is little,
Do not produce infrasonic wave.Compared with horizontal-shaft wind turbine, vertical axis windmill may utilize dimensional airfoil blade,
The lift that can utilize blade, the thrust (also referred to as resistance) that blade can be utilized again；The each blade of its wind wheel is at wind
Exerting oneself during difference when power machine runs, but take over rotation successively and exert oneself, blade load cyclically-varying is (vertical
Axle blade rotates one week, the angle of attack experience 360 ° of changes, only angle of attack blade ability in the range of about ± 20 °
Exert oneself, be in stall conditions at other angular ranges and can not exert oneself).These features of vertical axis windmill

Corresponding rotating speed is less than Equations of The Second Kind blade.
At present, utilize the vertical axis windmill of lift-type airfoil fan, substantially use Darrieus technology
" Φ " wind wheel or " H " wind wheel, the common characteristic of both wind wheels is main axis length >=wind wheel height,
Thus both wind wheel centers of gravity are higher, in order to ensure the stability of whole wind wheel, it is desirable to wind turbine main shaft has
The highest strength and stiffness, cause main shaft weight the heaviest.Wherein, " Φ " wind wheel is by " rope skipping curve " shape
Aforementioned Equations of The Second Kind blade constitute (generally using thin airfoil type blade), blade two ends be directly connected in main shaft (if
Solve " Φ " wind wheel from turn, the aforementioned first kind blade of serpentine also can be connected to main shaft).“Φ”
The blade that wind wheel uses to have enough flexibilities, its CpmaxCorresponding tip-speed ratio λ is higher, causes " Φ "
Low wind speed poor performance in wind wheel." H " wind wheel great majority are connected to by cantilever by aforementioned 3rd class blade
Main shaft forms, and trembles for suppression blade, it is desirable to cantilever has the highest strength and stiffness, causes cantilever weight
Measure the heaviest；Meanwhile, the 3rd class blade CpmaxCorresponding Optimum Leaves width (also referred to as chord length) ratio aforementioned second
Class blade wants big 50-60%, correspondingly, leaf weight 80-100% to be weighed.It is limited by this, identical
Under height, 1-2 times to be weighed of weight ratio " Φ " wind wheel of " H " wind wheel, its centrifugal load is bigger, to master
The strength and stiffness of axle require higher.
As can be seen here, lower the center of gravity and alleviate weight, increasing high CpmaxThe torque that rises of aerofoil profile is design height
Two technological break-through points of effect wind energy conversion system, particularly improve the break-through point of low wind speed performance in wind energy conversion system.
