Part.Existing blade of wind-driven generator is all made of single layer blade setting, the not high and low wind speed starting of generally existing wind energy utilization
Difficult problem.
It can be seen that above-mentioned existing pneumatic equipment bladess are in structure and use, it is clear that there are still there is inconvenient and defect, and
It needs to be further improved.A kind of new pneumatic equipment bladess how are founded, wake flow can be made full use of, greatly improve leaf
Piece lift resistance ratio improves generated energy, and becoming current industry pole needs improved target.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of pneumatic equipment bladess, can make full use of wake flow, substantially mention
High blade lifting resistance ratio improves generated energy, to overcome the shortcomings of existing pneumatic equipment bladess.
In order to solve the above technical problems, the present invention provides a kind of pneumatic equipment bladess, including multiple groups centered on wheel hub uniformly
The blade of setting, every group of blade include primary blades and auxiliary blade, and the auxiliary blade is respectively less than described on length of blade and width
Primary blades, and the upwind side that the primary blades are set that the auxiliary blade is parallel,
The primary blades are fixedly connected with auxiliary blade by connecting shaft, and the connecting shaft is rotatably connected with wheel hub.
As an improvement of the present invention, the auxiliary blade and primary blades parallel misalignment are arranged.
It is further improved, the leading edge of the auxiliary blade is shifted to install to the rear direction of the primary blades.
It is further improved, the auxiliary blade uses thin wing blade.
It is further improved, the pneumatic equipment bladess include three groups of blades being circumferentially arranged radially.
It is further improved, the side of the connecting shaft is rotatably connected with the blade root top stretched out by wheel hub by pitch-controlled system
It connects.
By adopting such a design, the present invention has at least the following advantages:
Auxiliary blade is arranged by the upwind in primary blades in the present invention, forms the blade group of double lifting surfaces, also passes through main lobe
The parallel misalignment of piece and auxiliary blade arrangement, is able to achieve and effectively captures compressed high pressure draught, greatly improve blade lifting resistance ratio, make
The wind energy utilization of the blade greatly improves, and improves generated energy, and then increase economic efficiency.
The present invention is connect by connecting shaft with pitch-controlled system, and the pitch of primary blades and auxiliary blade can be adjusted according to practical wind regime
Angle, to achieve the purpose that obtain maximal wind-energy and protect wind energy conversion system safety.
Detailed description of the invention
The above is merely an overview of the technical solutions of the present invention, in order to better understand the technical means of the present invention, below
In conjunction with attached drawing, the present invention is described in further detail with specific embodiment.
Fig. 1 is the structural schematic diagram of pneumatic equipment bladess of the present invention.
Fig. 2 is the side view of one group of blade of pneumatic equipment bladess of the present invention.
Fig. 3 is that the pneumatic of pneumatic equipment bladess of the present invention flows to schematic diagram.
Specific embodiment
The present embodiment carries out specifically completely new aerodynamic arrangement's blade by taking horizontal shaft wind-driven generator vane as an example
It is bright.
Referring to shown in attached Fig. 1 and 2, the present embodiment pneumatic equipment bladess, including three groups of radially uniform settings centered on wheel hub
Blade, every group of blade includes primary blades 1 and auxiliary blade 2, which is respectively less than primary blades 1 on length of blade and width,
And the parallel upwind side that primary blades 1 are set of auxiliary blade 2.
Preferred embodiment is, which is arranged with 1 parallel misalignment of primary blades, and the leading edge of the auxiliary blade 2 is to primary blades
1 rear direction shifts to install, as shown in Figure 1.
More excellent embodiment is that the auxiliary blade 2 uses thin wing blade.
The primary blades 1 are fixedly connected with auxiliary blade 2 by connecting shaft 3, which is rotatably connected with wheel hub 5.It is more excellent
For the side of the connecting shaft 3 is rotatably connected with 4 top of blade root stretched out by wheel hub 5 by pitch-controlled system.The then pitch-controlled system
It can realize the propeller pitch angle of adjustment primary blades and auxiliary blade, according to practical wind regime to obtain maximum wind energy and protection wind energy conversion system peace
Entirely.
Referring to shown in attached drawing 3, the design principle of pneumatic equipment bladess of the present invention are as follows: by increasing volume in traditional blades upwind
Outer lifting surface blade forms the stereoscopic arrangement of double lifting surfaces, and when the blade of double lifting surfaces receives wind energy, wind energy is through primary blades
Leeward surface pressure is apparently higher than surface pressure windward after compressing between 1 and auxiliary blade 2, and blade 2 is designed using thin wing because supplemented by,
Resistance increase is smaller, then the auxiliary blade 2 obtains biggish lift.So the blade of double lifting surfaces can effectively capture pressure
High pressure draught after contracting can greatly improve the lift resistance ratio of blade, greatly improve wind energy utilization.
Certainly, the blade combination of the double lifting surfaces of the present invention can also be used in other multiple groups horizontal axis wind-driven generators or vertical axis
In wind-driven generator, compression wake flow can be made full use of, improves wind energy utilization, improves generated energy, and then increase economic efficiency.
The above described is only a preferred embodiment of the present invention, be not intended to limit the present invention in any form, this
Field technical staff makes a little simple modification, equivalent variations or modification using the technology contents of the disclosure above, all falls within this hair
In bright protection scope.
