Description
Technical field
The present invention relates to electrical generator fields are and in particular to a kind of ring cover wind-driven generator with ring motor.
Background technology
Existing electromotor, as shown in figure 1, because shroud length, size are big, heavier, have impact on the economy of whole unit
Property.The length how reducing big angle of flare shroud has become the key issue improving the bell-type wind-driven generator market competitiveness.Logical
Cross to blower fan manufacturing cost and economic analysis, we calculate B≤0.33D2, be both economical.It means that should
When pipe range shortening 67%.However, pipe range shortens, " shroud " has just become " ring cover ", occurs in that boundary-layer separation problem.As Fig. 2
Shown, there is separation drastically in the postmedian of ring cover in attached surface current, the phenomena impair of this disengaging speed(-)up effect of ring cover.
In the classical works of air force engineering " air-flow separating dynamics ", the solution of proposition is " in the middle part of ring cover
Air blast ".Take this method can accomplish B≤0.33D2, its mechanism is：Near the space blown, local in boundary-layer
Separate, produce little whirlpool.Subsequent " attached again " again is in ring cover inner face.Thus having kept boundary-layer, maintain the speed(-)up effect of ring cover, such as
Shown in Fig. 3.But, this method needs additional blow gas equipment, and needs power consumption.Often inapplicable in actual applications
's.
Content of the invention
For solving the above problems, the invention provides a kind of ring cover wind-driven generator with ring motor, have steadily
The performance to wind performance, efficient power generation performance, sensitive starting performance and strong wind stall.
For achieving the above object, the technical scheme that the present invention takes is：
There is the ring cover wind-driven generator of ring motor, including annular rare earth permanent-magnetic generator, the shaftless wind wheel of multiple-blade, ring
Shape rotor and its annular brace, aerofoil profile section cover body, the supporting construction of head and pylon；The shaftless wind wheel of multiple-blade is located at annular and turns
Son is internal and supported spacing and supported by aerofoil profile section cover body annular；Ring-shaped rotor is located at the outer of the shaftless wind wheel of multiple-blade
Edge, is formed by some silicon steel plate packings, and inside studs with multipair Nd-Fe-B magnet steel, and as the annular brace of wind wheel, annular rare earth is forever
The stator of magnetic generator is set in the throat of aerofoil profile section cover body, is formed by some silicon steel plate packings, does not have a brush, the drawing of coil
Outlet is arranged in aerofoil profile section cover body；Aerofoil profile section cover body is connected with pylon by the supporting construction of head；Described aerofoil profile is broken
Mask body includes front shroud and back cover, and front shroud section is streamline aerofoil profile, and back cover is shell wing；It is provided with seam between front shroud and back cover
Gap, and make cover type being consistent property of curve.
The invention has the advantages that：
1) smoothly to wind performance：Can be steadily to wind more than or equal to 0.3m/s；
2) efficient power generation performance：Due to the negative pressure-pumping effect of ring cover, wind speed can be made to increase and to reach one times of wind power increase by 8
Times, generating effect is obvious；
3) sensitive starting performance：Because rotor diameter is little, rotary inertia less, can catch the energy of fitful wind；
4) performance of strong wind stall：When wind speed is more than 7 grades (strong wind), stall effect shows, and need not adjust pitch,
Power Limitation effect can be played.

Specific embodiment
In order that objects and advantages of the present invention become more apparent, with reference to embodiments the present invention is carried out further
Describe in detail.It should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not used to limit this
Bright.
As shown in figure 4, embodiments providing a kind of ring cover wind-driven generator with ring motor, including annular
The shaftless wind wheel of rare earth permanent-magnetic generator, multiple-blade, ring-shaped rotor and its annular brace, aerofoil profile section cover body, the support knot of head
Structure and pylon；The shaftless wind wheel of multiple-blade positioned at ring-shaped rotor inside and is supported spacing and propped up by aerofoil profile section cover body annular
Hold；Ring-shaped rotor is located at the outer rim of the shaftless wind wheel of multiple-blade, is formed by some silicon steel plate packings, inside studs with multipair neodymium-iron-boron
Steel, as the annular brace of wind wheel, the stator of annular rare earth permanent-magnetic generator is set in the throat of aerofoil profile section cover body, by some
Silicon steel plate packing forms, and does not have brush, and the lead-out wire of coil is arranged in aerofoil profile section cover body；Aerofoil profile section cover body passes through head
Supporting construction be connected with pylon；Described aerofoil profile section cover body includes front shroud and back cover, and front shroud section is streamline aerofoil profile, and back cover is
Shell wing；It is provided with gap between front shroud and back cover, and makes cover type being consistent property of curve, so can make full use of nature
Wind, need not additional blowing device, auspicious see Fig. 5.When natural wind is along the smooth-going flowing of front cover outer surface, can uniformly effectively backward
Cover inwall is blown, and supplements energy to attached surface current, so that attached surface current is smoothly flowed toward back cover inner face, thus avoiding dividing of boundary-layer
From.It is understood that design of accurately cracking, this effect can be reached.
Originally it is embodied as making cover length reduce 67%, meanwhile, also make ring cover material reduce 2/3；Blower fan cost reduces by one
Half.Need to handle well the articulation issues of front shroud and back cover using this device.We pass through to make 4 ring cover moulds, three increasings
Strong floor and a fan supporter solve articulation issues, and by prototype experiment it was confirmed the reliability of this device and having
Effect property this unit run 1 year in Huhehaote Da Latumu village, after move to Folium Isatidis at the foot of the hill, run 1 year, performance is very again
Good, in January, 2002 is transported to Badaling wind-power electricity generation experimental station, proceeds by and is tested comprehensively, treats laggard by expert testimony
Row industrialization is produced in batches, and puts on market.This type can start during light breeze to send out steadily to wind in force one wind
Electricity, remains to safe operation during fresh gale.Generating seriality is good compared with conventional FDJ-300W and FD-600W blower fan, every year may be used
Run 1000 hours with more.Annual many generatings 24% about.Its manufacturing cost is only high than conventional type by 15%, and the ratio of performance to price is high
7.8%, there is the very strong market competitiveness.Can be used as the renewal product of conventional type.
Apply this blower fan, on Inner Mongolian grassland, great Northwest borderland, southeastern coast island and highway both sides, every year
Can run, generate electricity 6000 hours by 8000 hours, have a extensive future.
Originally it is embodied as wind wheel efficiency high：Meet aerodynamic requirement, the antero-posterior pathway of wind wheel does not affect
Any object of air flow；The design of impeller outer shroud can prevent the micro- of blade from quivering and shaking, and efficiently reduces wind-driven generator
Vibration；Wind speed round becomes with wind speed size, and the high ratio of full blast speed section is all close to optimal value；Electric efficiency is high：Maximum limit
