Abstract
The invention discloses a multi-system combined structure for impellers of an H-shaped vertical axis wind turbine, relates to a structure of the H-shaped vertical axis wind turbine and aims to realize low-air-speed startup while higher efficiency of the H-shaped vertical axis wind turbine is achieved. Two or more impellers are fixedly arranged in series on one wind wheel main shaft; the distance (H) between every two wind wheels is 1-3 meters in the axial direction; the serial impellers are provided with the same quantity of blades; the serial impellers are H-shaped; the serial impellers are combined in the forms of symmetrical wings and asymmetrical wings respectively. The serial wind wheels have different geometric parameters, and each impeller is an independent system, so that respective advantages can be brought into play.
Description
Technical field
The present invention relates to the structure of H type vertical axis aerogenerator.
Background technique
Along with the utilization of continually developing of wind-powered electricity generation, vertical axis windmill has been subjected to social concern and the favor in market, and what it was the most representative is exactly H type vertical axis windmill, and maximizes, and high-performance will be the H type vertical axis windmill developing direction in future; Fig. 1, Fig. 2 are the structural type of current H type vertical axis wind turbine rotor, on an axle, fixedly mount an impeller, at patent name, being in a kind of patent of the vertical axis windmill with multilayer wind wheel, is to have adopted the impeller that structure is identical to be staggered installation of on main shaft.Structural type for the H type vertical axis wind turbine rotor of current existence, can not bring into play different airfoil profiles simultaneously, different rotor solidities, and the wind speed feature advantage of different heights position, be embodied on whole wind energy conversion system and under low wind speed, can not start exactly, the efficiency of output is not high yet, or startability and high efficiency can not meet simultaneously, and this is aobvious more outstanding on large-scale H type vertical axis windmill.
Summary of the invention
The object of the invention is to realize low wind speed when reaching H type vertical axis windmill greater efficiency starts.
The present invention is a kind of multisystem composite structure of H type vertical axis wind motor blade wheel, on same main shaft, fixedly mounts two or more impellers, and two or more impeller serials are installed; The structural type of series connection impeller is H type, and between series connection impeller, span H is in the axial direction 1m ~ 3m; Series connection impeller is used respectively the combining form of symmetrical airfoil and asymmetric airfoil, and the aerofoil profile that same impeller is used is identical.
The beneficial effect that the present invention reaches: 1,, on same H type vertical axis windmill, simultaneously brought into play symmetrical airfoil and asymmetric airfoil advantage separately; 2, on same H type vertical axis windmill, the impeller of different soliditys combines, and contributes to implementation efficiency to maximize; 3, on the H type vertical axis windmill maximizing, can be according to the feature design impeller of different heights wind speed; 4, on same H type vertical axis windmill, each impeller is an independently system, and can bring into play system advantage separately, and the advantage of each system is embodied on whole wind energy conversion system the most at last.
accompanying drawing explanation
Fig. 1 is for adopting at present the plan view (take 4 blades as example) of more H type vertical axis wind motor blade wheel structure, Fig. 2 is the plan view of structure shown in Fig. 1, Fig. 3 is that the plan view of H type vertical axis wind motor blade wheel multisystem combining form of the present invention is (with 2 impellers, 4 blades of each impeller are example), Fig. 4 is the plan view of H type vertical axis wind motor blade wheel multisystem combining form of the present invention, and Fig. 5 is the angle of attack variation rule figure of H type vertical axis windmill under different orientations.
Embodiment
As shown in Figure 3, the present invention is a kind of multisystem composite structure of H type vertical axis wind motor blade wheel, on same main shaft, fixedly mounts two or more impellers, and two or more impeller serials are installed; The structural type of series connection impeller is H type, and between series connection impeller, span H is in the axial direction 1m ~ 3m; Series connection impeller is used respectively the combining form of symmetrical airfoil and asymmetric airfoil, and the aerofoil profile that same impeller is used is identical.
On described same main shaft, two impellers of series connection fixed installation, are 1m ~ 3m at axial span H between impeller.
The plural impeller of series connection fixed installation on described same main shaft, between impeller, span H is in the axial direction 1m ~ 3m.
As shown in Figure 4, the blade first setting angle α 1=2 degree of described series connection impeller, the second setting angle α 2=4 degree.
The lobe numbers of described series connection impeller is identical.
By instantiation of the present invention below, can further clearly understand the present invention, but they not limitations of the present invention.
as shown in Figure 3,what blade 4 was used is NACA0018 aerofoil profile, and chord length is 0.15m, the first setting angle α
1be 2 °, and be fixed connection by link 5; What blade 6 was used is Goe63 aerofoil profile, and chord length is 0.34m, the second setting angle α
2be 4 °, and be fixed connection by link 7, two impeller 1 and impellers 3 that structure is different of series connection fixed installation on main shaft 2.Wherein impeller 1 diameter 1.2m, is highly 1.2m, and wherein impeller 3 diameter 1m, are highly 1m, the setting angle of two impellers differs 45 degree, i.e. blade 1-1 as shown in Figure 4,1-2,1-3,1-4 represents 4 blades of wind wheel 3, blade 2-1,2-2,2-3,2-4 represents 4 blades of wind wheel 1, angle between corresponding blade is as 1-1 and 2-1,1-2 and 2-2,1-3 and 2-3,1-4 and 2-4 are 45 °, and wind wheel clockwise direction rotates, and incoming flow is the uniform incoming flow along X-axis postive direction.
Using position shown in Fig. 4 as analyzing reference.The installation of impeller 3 has been equivalent to increase the number of blade of whole wind turbine impeller, known according to the graph of a relation of Fig. 5 different orientations and the angle of attack, this has reduced the startup dead point of whole wind wheel, simultaneously blade 6 is used be ratio of lift coefficient to drag coefficient larger have a camber aerofoil profile, these self-startings to H type vertical axis windmill are favourable.
Be directed to whole wind wheel, in the situation that impeller height overall is equal, the existence of wind wheel 1 in Fig. 3, the more blade that has been equivalent on the rotation round of whole wind wheel layout, on each wind wheel, do not change again its stream field structure, such structure can guarantee always to have blade to be in the position that utilizes preferably wind energy in the movement process of the one-period of wind wheel, is conducive to improve wind energy utilization.
Above mode of execution, reflects feature and the compound mode of H type vertical axis wind motor blade wheel multisystem combining form.
