Description
Technical field
The utility model is related to electrical generator fields, and in particular to a kind of ring cover wind-driven generator with ring motor.
Background technology
Existing generator, as shown in figure 1, because shroud length, size are big, heavier, have impact on the economy of whole unit
Property.How to reduce the length of big angle of flare shroud turns into the key issue for improving the bell-type wind-driven generator market competitiveness.It is logical
Cross to blower fan manufacturing cost and economic analysis, we calculate B≤0.33D2, be both economical.It means that
Pipe range should be shortened 67%.However, pipe range shortens, " shroud " just into " ring cover ", occurs in that boundary-layer separation problem.As schemed
Shown in 2, in the postmedian of ring cover separation drastically occurs for 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 ".This method is taken to accomplish B≤0.33D2, its mechanism is：Boundary-layer occurs local near the space of air blowing
Separation, produces small whirlpool.Subsequent " attached again " again is in ring cover inner face.So as to keep boundary-layer, the speed(-)up effect of ring cover is maintained, such as
Shown in Fig. 3.But, this method needs additional blow gas equipment, and need to consume power.It is often inapplicable in actual applications
's.
Utility model content
To solve the above problems, the utility model provides a kind of ring cover wind-driven generator with ring motor, have
Smoothly to wind performance, efficient power generation performance, sensitive starting performance and the performance of strong wind stall.
To achieve the above object, the technical scheme that the utility model is taken is：
Ring cover wind-driven generator with ring motor, including the shaftless wind wheel of annular rare earth permanent-magnetic generator, 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 turned
Son is internal and by the support of aerofoil profile section cover body annular is Lai spacing and support；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, without brush, and coil draws
Outlet is arranged in aerofoil profile section cover body；Aerofoil profile section cover body is connected by the supporting construction of head with pylon；The 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；Provided with seam between front shroud and back cover
Gap, and make being consistent property of cover type curve.
The utility model 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：Because the negative-pressure ward of ring cover is acted on, wind speed can be made to increase up to one times of wind power increase by 8
Times, generating effect is obvious；
3) sensitive starting performance：Because rotor diameter is small, 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 is shown, without adjusting pitch,
Power limit effect can be played.

Embodiment
In order that the purpose of this utility model and advantage are more clearly understood, the utility model is entered with reference to embodiments
Row is further described.It should be appreciated that specific embodiment described herein is only to explain the utility model, and without
In restriction the utility model.
As shown in figure 4, the utility model embodiment provides a kind of ring cover wind-driven generator with ring motor, including
The shaftless wind wheel of annular rare earth permanent-magnetic generator, multiple-blade, ring-shaped rotor and its annular brace, aerofoil profile section cover body, the branch of head
Support structure and pylon；The shaftless wind wheel of multiple-blade be located at ring-shaped rotor inside and by aerofoil profile section cover body annular support come it is spacing with
Support；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
Magnet 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, if by
