Description
Technical field
The utility model relates to pneumatic equipment bladess technical fields, more particularly to a kind of pneumatic equipment bladess.
Background technique
Wind power generating set will obtain biggish wind-power electricity generation power, and key is to there is efficient blade.Blade
Design of Aerodynamic Configuration, structure type, directly affect the performance and power of wind power generation plant, be most crucial in wind-driven generator
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.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of pneumatic equipment bladess, can make full use of wake flow, greatly
Width improves blade lifting resistance ratio, generated energy is improved, to overcome the shortcomings of existing pneumatic equipment bladess.
In order to solve the above technical problems, the utility model provides a kind of pneumatic equipment bladess, including multiple groups are centered on wheel hub
The blade being uniformly arranged, every group of blade include primary blades and auxiliary blade, and the auxiliary blade is respectively less than on length of blade and width
The 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 a kind of improvement of the utility model, 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 utility model at least has the following advantages:
Auxiliary blade is arranged by the upwind in primary blades in the utility model, forms the blade group of double lifting surfaces, also passes through
The parallel misalignment of primary blades and auxiliary blade arrangement, is able to achieve and effectively captures compressed high pressure draught, greatly improves blade and rises resistance
Than greatly improving the wind energy utilization of the blade, improving generated energy, and then increase economic efficiency.
The utility model is connect by connecting shaft with pitch-controlled system, can be according to practical wind regime adjustment primary blades and auxiliary blade
Propeller pitch angle, to achieve the purpose that obtain maximal wind-energy and protect wind energy conversion system safety.
Detailed description of the invention
Above-mentioned is only the general introduction of technical solutions of the utility model, in order to better understand the technology hand of the utility model
Section, below in conjunction with attached drawing, the utility model is described in further detail with specific embodiment.
Fig. 1 is the structural schematic diagram of the utility model pneumatic equipment bladess.
Fig. 2 is the side view of one group of blade of the utility model pneumatic equipment bladess.
Fig. 3 is that the pneumatic of the utility model pneumatic equipment bladess 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 the utility model pneumatic equipment bladess are as follows: by increasing in traditional blades upwind
Add additional lifting surface blade, forms the stereoscopic arrangement of double lifting surfaces, when the blade of double lifting surfaces receives wind energy, wind energy is through master
Leeward surface pressure is apparently higher than surface pressure windward after compressing between blade 1 and auxiliary blade 2, and blade 2 is set using thin wing because supplemented by
Meter, resistance increase is smaller, then the auxiliary blade 2 obtains biggish lift.So the blade of double lifting surfaces can effectively be caught
Compressed high pressure draught is obtained, the lift resistance ratio of blade can be greatly improved, greatly improve wind energy utilization.
Certainly, the blade combination of the double lifting surfaces of the utility model can also be used in other multiple groups horizontal axis wind-driven generators or hang down
In d-axis wind-driven generator, compression wake flow can be made full use of, improves wind energy utilization, improves generated energy, and then is improved economical
Benefit.
The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model
Limitation, those skilled in the art make a little simple modification, equivalent variations or modification using the technology contents of the disclosure above,
It falls within the protection scope of the present utility model.
