Further, in each blade unit, the blade equidistant arrangement.It is understood that the distance between blade
Relevant with the number of blade and wind wheel size, distance is appropriate between blade, it is not too near also should not be too remote, when wind wheel size
Necessarily, lobe numbers are more, and distance is nearer between blade, can greatly increase the resistance that gas passes through, and air-flow separately can bypass leaf
Piece flows to rear, and only fraction is done work by blade, so the wind power that blade is actually obtained is reduced；And in wind wheel
In the case that size is certain, blade closely causes very much blade to partly overlap, and wind area reduces, and wind surface wind resistance is reduced,
This is also the reason for multiblade fan cannot get more wind energies；But blade is very little, most of wind are all from the gap between blade
Leak, the wind energy for obtaining is not also high.
Further, the blade is planar shaped, folding face shape or arc surfaced, preferably arc surfaced.

The concave surface of virtual fan blade aweather when, the luvisde of blade is also its concave surface.After the projection in the horizontal direction of each blade, each
Tangential direction at blade convex surface peak is parallel, and the tangential direction and horizontal direction at each blade convex surface peak
Angle can change in the range of 0-90 °.When air-flow blows to the convex surface of virtual fan blade with horizontal direction, the convex surface of blade is also located
In luvisde, the fraction of convex surface is leaked out from the gap between corresponding blade, into convex surface behind, the air-flow of leakage
The resistance of part convex surface can not only be offset, convex surface drop in resistance 20-80% is made, but also lift can be produced in the concave surface of blade,
Promote wind wheel to rotate forward, therefore substantially increase the efficiency of resistance force type vertical shaft wind machine.When angle theta is 30-60 °, blade

It is many.
Further, the virtual fan blade is planar shaped, folding face shape or arc surfaced.Specifically, when virtual fan blade is plane
When shape, folding face shape or arc surfaced, blade can be any one in folding face shape or arc surfaced；When virtual fan blade is planar shaped,
The lobe numbers that each blade unit includes are that folding face shape or arc surfaced are few compared with virtual fan blade because virtual fan blade be folding face shape or
During arc surfaced, with staggered, therefore more blades can be arranged between blade, the overlap ratio between two blades is
0.2-0.8。
Further, the blade one side is rough surface, and another side is smooth surface；When the blade is arc surfaced
When, the concave surface of blade is rough surface, and convex surface is smooth surface.Rough surface is conducive to absorption of the blade to wind energy, design one
The blade of the coarse one-sided smooth in face, is conducive to further improving the resistance difference of wind wheel both sides blade；It is recessed when blade is arc surfaced
Face is designed as rough surface, and convex design is smooth surface, when horizontal direction has wind so that the wind that concave surface face aweather is subject to
The difference increase of the wind resistance that resistance and convex surface face aweather is subject to, the efficiency for making blower fan is further improved.
The present invention replaces the fan blade of resistance force type vertical shaft wind machine using multiple blades, by the multiple leaves in each blade unit

Specific embodiment
The principle and feature of the present invention are described below in conjunction with accompanying drawing, example is served only for explaining the present invention, and
It is non-for limiting the scope of the present invention.
Fig. 1 for a kind of filter wind formula vertical axis wind turbine of one embodiment of the invention top view, including four
Blade unit 1 and rotating shaft 2, four blade units 1 are uniformly distributed along the periphery of rotating shaft 2, four blade units 1 each
Blade unit 1 includes multiple blades 11 being longitudinally arranged, and in the present embodiment, the blade 11 is arc surfaced；The blade 11
Number can be according to the type of wind-driven generator depending on, the present invention filter wind formula wind wheel, can be used for plain edition, large-scale or super large
Type vertical axis aerogenerator, in the embodiment shown in fig. 1, each blade unit 1 is made up of 6 blades 11, each blade

3 and six time support bars 4, one end of the main support rod 3 is connected and is uniformly distributed in the plane vertical with rotating shaft 2 with rotating shaft 2
On, the other end of each main support rod 3 is connected with secondary support bar 4, and the blade 11 connects one to one in described support bar 4
The other end；Wherein, in each connecting elements, described time support bar 4 can be with parallel, it is also possible in flaabellum shape distribution；Another
In planting embodiment, in order that blade 11 is stronger being fixed in rotating shaft 2, two groups of above-mentioned connecting elements structures can be set,
Per group is located at respectively in two planes up and down vertical with rotating shaft 2, and the top of every group of connecting elements difference support blade 11 is with
Portion；
In another embodiment, the connecting elements is circular mounting plate and bottom plate, multiple blade lists
Unit is evenly arranged between mounting plate and bottom plate and the lower edges of the blade are corresponding solid with mounting plate and bottom plate respectively

In the embodiment shown in Fig. 1, larger space is set between each blade unit 1, in each blade unit 1
Blade 11 is equidistantly staggered, if distance is too near between blade 11, can greatly increase the resistance that gas passes through, air-flow can separate around
Cross blade 11 and flow to rear, only fraction is done work by blade 11, so the wind power that blade 11 is actually obtained is reduced；
But blade 11, away from too far away, most of wind are all leaked from the gap between blade 11, and the wind energy for obtaining is not also high；And
In the case where wind wheel size is certain, blade 11 closely causes very much blade to partly overlap, and wind area reduces, wind surface windage
Power is reduced, and this is also the reason for multiblade fan cannot get more wind energies；In the present embodiment, due to existing between blade 11
Space, even if two overlap ratios of blade 11 are larger, will not also hinder the overlap ratio between flowing through for wind, therefore two blades 11
For 0.8.
In each blade unit 1, the proper alignment of the blade 11, the ipsilateral penumbra of the blade 11 is virtual positioned at an arc

The fraction in face is leaked out from the gap between corresponding blade 11, and, the air-flow of leakage can not only be supported into convex surface behind
Disappear the resistance of part convex surface, makes convex surface drop in resistance 20-80%, but also can produce lift in the concave surface of blade 11, promotes wind
Wheel is rotated forward, therefore substantially increases the efficiency of resistance force type vertical shaft wind machine.Angle theta can be more than 0 ° in principle, less than 90 °
In the range of change, but θ is bigger, and the convex surface resistance of blade 11 is bigger, and the difference of concave surface and convex surface resistance is less, and wind energy utilization is got over
It is low；θ is less, and air-flow major part is leaked out from the gap of blade 11, and the wind resistance of concave surface is also reduced, and wind energy utilization is still not
Height, therefore θ is arranged in the range of 30-60 °, the wind resistance that now concave surface of blade 11 face aweather is subject to and convex surface face aweather
The difference of the wind resistance being subject to is maximum, and the efficiency of blower fan improves most.
It is emphasized that not only the air-flow of convex surface from letting out between blade 11, the air-flow of concave surface also can be from blade
Let out between 11, but air-flow two sides flow velocity and differ, the air velocity of the airflow velocity ratio concave surface of convex surface is fast, because
This convex surface airflow leaks is more compared with concave surface airflow leaks, and the difference of the resistance of concave surface and convex surface still becomes greatly.
In another kind of embodiment, the concave surface of blade 11 is rough surface, and convex surface is smooth surface, and rough surface is conducive to
Absorption of the blade to wind energy, when horizontal direction has wind so that the wind resistance that concave surface face aweather is subject to and convex surface face aweather
The difference of the wind resistance being subject to further increases, and the efficiency for making blower fan is further improved.
The foregoing is only presently preferred embodiments of the present invention, not to limit the present invention, all spirit in the present invention and
Within principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
