The outer diameter of quiet fin 8 is bigger than the outer diameter of dynamic fin 5.That is, the radial direction length of fixed blade 7 is configured to than rotation The radial direction length of blade 4 is long.

Oral area 9 has most small diameter portion 9x.In most small diameter portion 9x, the gap with the outer circumference end of the rotating vane 4 of dynamic fin 5 For minimum.In addition, in Fig. 1, most small diameter portion 9x by include the straight line portion being extended in axial direction with certain diameter circle Cylinder face is constituted, but can also be configured to the circumference for not having certain diameter of straight line portion.The diameter of oral area 9 is with from minimum Diameter portion 9x goes to discharge side and is expanded, and discharge side opening portion 9y is formed in the end of discharge side.In addition, the diameter of oral area 9 With expanding from most small diameter portion 9x to suction side, suction side opening portion 9z is formed in the end of suction side.

In dynamic fin 5, the position of axis direction is adjusted, so that the periphery of edge, that is, rear of the discharge side of rotating vane 4 End is opposite with the most small diameter portion 9x of oral area 9.In addition, in dynamic fin 5, the position of axis direction is adjusted, so that the row of rotation hub 3 Go out side the most small diameter portion 9x opposite with the most small diameter portion 9x of oral area 9 or positioned at oral area 9 in end and discharge side opening portion 9y it Between.

In quiet fin 8, the position of axis direction is adjusted, so that the edge of the suction side of fixed blade 7, that is, up-front periphery End is between the most small diameter portion 9x and discharge side opening portion 9y of oral area 9.In addition, quiet fin 8 is arranged to before fixed blade 7 Gap S as defined in being formed between the outer circumference end and oral area 9 of edge side.The outer diameter of quiet fin 8 is bigger than the outer diameter of dynamic fin 5 and oral area 9 Diameter go and expand to discharge side, thus the outer circumference end of the rear of rotating vanes 4 of the gap S with moving fin 5 with oral area 9 most The gap of small diameter portion 9x is roughly the same.In addition, in quiet fin 8, the position of axis direction is adjusted, so that the sucking of anchor hub 6 The end of side is located between the most small diameter portion 9x of oral area 9 and discharge side opening portion 9y.

Here, the shape of the fixed blade 7 of quiet fin 8 is described in detail.

As shown in Figure 1, the meridian plane height h2 of fixed blade 7, from the anchor hub side 7a at the end as 6 side of anchor hub to Outer circumference end 7b is substantially certain.In addition, Fig. 2 is as indicated, on the face vertical with the rotary shaft 2 of dynamic fin 5, before fixed blade 7 Edge be located at the reverse rotation direction of the rotating vane 4 of dynamic fin 5 relative to anchor hub side 7a by outer circumference end 7b in a manner of relative to Radial direction is obliquely installed.

Fig. 3 A are the sections 3A-3A of Fig. 1, the section of hub side.Fig. 3 B are the sections 3B-3B of Fig. 1, are the sections of peripheral side. Fig. 3 C are the sections 3C-3C of Fig. 1, the section of outer circumference end.Fig. 3 A~Fig. 3 C are the rotations for indicating the section in same radial location Blade 4 and the air stream of the cross sectional shape and driven fin 5 of fixed blade 7 discharge are with the blade angle θ's of fixed blade 7 The figure of relationship.Here, blade angle θ is the angle indicated relative to the face vertical with rotary shaft 2.Fig. 4 is to indicate fixed leaf The figure of the radial direction position of piece 7 and the relationship of blade angle θ.

As shown in Fig. 3 A~Fig. 3 C, rotating vane 4 have in the convex arc-shaped in the reverse rotation direction of dynamic fin 5 or Rotation hub 3 is obliquely fixed in the section of wing in such a way that rotating vane rear 4a is located at discharge side relative to rotary shaft 2. Fixed blade 7 has in the section of the convex arc-shaped or wing in direction of rotation of dynamic fin 5, has to be located at leading edge 7c and inhale Enter the mode of side relative to also pacify as the inclined blade in the face of the central axis of the anchor hub 6 of the central shaft of quiet fin 8 It is fixed on anchor hub 6 to dress angle θ.Here, blade angle θ is by the edge of the suction side of fixed blade 7 i.e. leading edge 7c and blowout The horizontal plane angulation of the straight line and the central shaft perpendicular to anchor hub 6 of the 7d connections of the edge of side, that is, rear, be from perpendicular to The angle that the horizontal plane of the central shaft of anchor hub 6 more goes more becomes larger to the reverse rotation direction side of suction side or dynamic fin 5.

Moreover, the blade angle θ of fixed blade 7 is configured to different according to the position of the radial direction of fixed blade 7.

As shown in Fig. 3 A, Fig. 4, in the end that fixed blade 7 is contacted with anchor hub 6 (anchor hub side 7a), blade installation Angle θ a are minimum.Moreover, as the peripheral side of the radial direction to fixed blade 7 is gone, blade angle θ expands, such as Fig. 4 institutes Show, is blade angle θ m in the central portion 7m of fixed blade 7.As side is gone further out compared with central portion 7m, leaf Piece established angle θ further expands, and is maximum (leaf as shown in Fig. 3 B, Fig. 4, between the outer circumference end 7b of central portion 7m and fixed blade 7 Piece established angle θ b).Compared with as the position of blade angle θ b outer peripheral side, blade angle θ taper into, such as scheme It is blade angle θ c in the outer circumference end 7b of fixed blade 7 shown in 3C, Fig. 4.Leaves of the blade angle θ c than anchor hub side 7a Piece established angle θ a are big, and the blade angle θ m than central portion 7m are small.

That is, blade angle θ b, θ c of side more outer than central portion 7m, are more than the leaf for leaning on 6 side of anchor hub than central portion 7m Piece established angle θ ab.In addition, in side more outer than central portion 7m, blade angle θ b are maximum.

Moreover, the meridian plane height of fixed blade 7 and the position of radial direction are unrelated and approximately fixed, fixed blade 7 Blade angle θ is different according to the position of radial direction, so fixed blade 7 is in the anchor hub side contacted with anchor hub 6 The curvature of 7a, circular arc are minimum, and the curvature of circular arc is maximum between central portion 7m and outer circumference end 7b.In addition, at outer circumference end 7b The curvature of the circular arc of fixed blade 7, the curvature than the circular arc at the 7a of anchor hub side is big, than the curvature of the circular arc at the places central portion 7m It is small.In addition, the curvature of the circular arc at side more outer than central portion 7m, the song with the circular arc than central portion 7m at 6 side of anchor hub Rate is compared to larger.

Then, the shape of the interconnecting piece of the fixed blade 7 of quiet fin 8 and supporting frame 11 is described in detail.Fig. 5 be from The major part stereogram of the fixed blade 7 of quiet fin 8 and the interconnecting piece of supporting frame 11 is seen in the sides rear 7d of fixed blade 7.Such as Shown in Fig. 5, in the outer circumference end 7b of fixed blade 7, only it is provided with fixed blade 7 in radius in the sides rear 7d of fixed blade 7 The extension 12 of extended plate on direction.The face face of recessed side (in fixed blade 7 become) for extension 12 with Curvature identical with the concave side of the circular arc of fixed blade 7 is formed, and on the other hand, the back side is with parallel with the central shaft of anchor hub 6 Face is formed.Therefore, the thickness of extension 12 is identical as the thickness of fixed blade 7 in extension rear 12a, but more to extension Leading edge 12b goes side more to thicken.In addition, the length (meridional section height) of the central axis direction of extension 12 is formed as than aftermentioned The length of the central axis direction of foot 13 is short.In addition, the meridional section height of extension 12 is formed as the position with radial direction It is independently substantially certain.

On the other hand, it is provided with to discharge side foot 13 outstanding in supporting frame 11.Foot 13 be two faces by with fixation The component of the plate of the parallel face formation of central shaft of hub 6, the thickness of foot 13 are identical as the thickness of fixed blade 7.In addition, foot The length of the central axis direction in portion 13 is formed as shorter than the meridian plane height h2 of fixed blade 7.In addition, as shown in Figure 1, foot 13 It is arranged to the position supporting and fixing blade 7 of the radial direction compared with the discharge side opening portion 9y with oral area 9 as peripheral side.

Moreover, by engaging 6 side end of anchor hub of the periphery side end of extension 12 and foot 13, fixed blade 7 The sides leading edge 7c formed between supporting frame 11 as defined in gap T, supported by supporting frame 11.In addition, fixed blade 7, extension Portion 12, foot 13, supporting frame 11 are formed as one, in terms of ensuring intensity preferably.

In addition, as shown in figure 5, foot 13 blowout side end 13a with extension 12 blowout side extension after Edge 12a, fixed blade 7 rear 7d be located at the mode of the same face and engaged.Therefore, the leading edge 7c and supporting frame of fixed blade 7 11 is prominent compared to suction side.In addition, the rear 7d of fixed blade 7 is prominent to discharge side compared with supporting frame 11.

In addition, as shown in Fig. 2, the length (radius of extension 12 that extension 12 is connect with fixed blade 7 and supporting frame 11 Direction length), it is different according to the position of installation fixed blade 7.Fixed blade 7 up and down positioned at gravity direction is prolonged Long portion 12 is shorter, and the extension for being located at the fixed blade 7 of other positions is longer.It, can be it is easy to ensure that will by using the structure Quiet fin 8 is held in the enough intensity of supporting frame 11.

In the present embodiment, the fixed blade 7 of quiet fin 8 is by being arranged circle centered on its periphery is by rotary shaft Cricoid supporting frame 11 is fixed in oral area 9 or shell.Therefore, it is pressed on the direction of dynamic fin 5 etc. in quiet fin 8 In the case of, the defined gap between quiet fin 8 and dynamic fin 5 can be also kept, the fixed blade 7 of quiet fin 8 can be prevented It is contacted with the rotating vane 4 of dynamic fin 5 and makes fin 5 and the deformation of quiet fin 8 or damaged.

In particular, in the present embodiment, multiple fixed blades 7 include extension 12 and exist from the outer circumference end of extension 12 The foot 13 that the side of oral area 9 upwardly extends is held in oral area 9 or shell by extension 12 and foot 13.Therefore, even if In quiet fin 8 being pressed on the direction of dynamic fin 5 in the case of displacement, displacement is also absorbed by extension 12 and foot 13, It being capable of anti-stop tabs 5 and the deformation of quiet fin 8 or damaged.

For the wind turbine that such as above mode is constituted, illustrate its action, effect below.

First, when making the rotation driving of rotary shaft 2 using motor 10, as shown in Fig. 2, dynamic fin 5 is in the counterclockwise direction Upper rotation is guided from the side configured with motor 10 by air to dynamic fin 5.At this point, utilizing multiple rotating vanes 4 and setting Oral area 9 around rotating vane 4 applies dynamic pressure and static pressure to air.

Then, the air (discharge air-flow) that driven fin 5 is discharged is directed to quiet fin 8.As shown in figure 3, being directed to The inflow velocity V of the air of quiet fin 8 has angle relative to the axis direction of rotary shaft 2, has the axis flowed in axial direction The stream direction ingredient Va and convolution direction ingredient Vt flowed on the direction of rotation of dynamic fin 5.Axial flow direction ingredient Va is and wind Measure related speed, but the direction ingredient Vt that circles round is vertical with axis direction, as circumferential direction ingredient, thus it is irrelevant with air quantity, It is agitation air, becomes loss energy when can not swimmingly turn in axial direction.

Then, using the quiet fin 8 with multiple fixed blades 7, reduce the convolution direction of the discharge air-flow for moving fin 5 at Point, it can will be recycled as static pressure as the convolution direction ingredient (swirling flow) of energy loss, thus, it is possible to improve static pressure efficiency And form air-supply effect.

Here, concentrating on the discharge of the dynamic fin 5 of side more outer than the central portion of the radial direction of rotating vane 4 with mainstream Correspondingly, the blade angle θ of fixed blade 7 is more than for the blade angle θ b of side more outer than central portion 7m than center air-flow Portion 7m depends on the blade angle θ a of 6 side of anchor hub.Therefore, with than central portion 7m by 6 side of anchor hub region compared with, quiet fin The region of the larger side more outer than central portion 7m of convolution direction ingredient of 8 inlet, can be by the inlet of fixed blade 7 Collision loss inhibit smaller, can efficiently will convolution velocity component be recovered as static pressure.

In addition, in the discharge side that dynamic fin 5 is axial-flow type or diagonal flow type, the only rotating vane 4 of dynamic fin 5 by oral area 9 In the case of the structure of encirclement, generates larger fin end in the periphery of rotating vane 4 and be vortexed, move the row of the peripheral side of fin 5 Go out air velocity to be greatly reduced.In particular, by fin end vortes interference, generate from the gap of oral area 9 and rotating vane 4 adverse current to When the leakage stream of suction side, the reduction that the axis direction ingredient of air-flow is discharged is very big.But in the present embodiment, phase therewith Ying Di, it is maximum, the outer circumference end of fixed blade 7 to make the blade angle θ between the central portion 7m and outer circumference end 7b of fixed blade 7 Blade angle θ c at 7b are smaller than the blade angle θ m that central portion 7m locates, so can be by the fixed blade 7 of quiet fin 8 The collision loss of outer circumference end 7b, fixed blade 7 inlet inhibits smaller.

Therefore, it is possible to, in peripheral side, efficiently convolution velocity component is recovered as quiet from the central portion 7m of fixed blade 7 Pressure, and even if being easy to be vortexed the fixed blade 7 influenced by the leakage stream of the rotating vane 4 of dynamic fin 5 and fin end Outer circumference end 7b, also can efficiently will convolution velocity component be recovered as static pressure.

In the region that the blade angle θ of the anchor hub side 7a from fixed blade 7 to peripheral side is the best part, The blade angle θ, particularly inlet angle of fixed blade 7 are consistent with the discharge air-flow angle of dynamic fin 5, so even if not passing through Increase the meridian plane height h2 of fixed blade 7 to increase chord-length, it also can be efficiently by the convolution of the discharge air-flow of dynamic fin 5 Velocity component is converted to static pressure.

In addition, more can inhibit chord-length that it is made not extend closer to the peripheral side of fixed blade 7, can inhibit because of fixation The increase lost caused by the skin-friction loss of blade 7 and the increase of the tail width of wake flow.

In addition, the leaf of blade angle θ at the outer circumference end 7b of fixed blade 7 than the region from central portion 7m to peripheral side Piece established angle θ hours, because of dynamic leakage stream between fin 5 and oral area 9 and the fin end whirlpool generated at the fin end of dynamic fin 5 Stream is easy to be influenced by the angle large variation of the discharge air-flow for the outer circumference end for carrying out automatic fin 5.But in this embodiment party In formula, the meridian plane height h2 of fixed blade 7 be arranged to substantially certain from anchor hub side 7a to outer circumference end 7b, be as a result, Make near the outer circumference end 7b of fixed blade 7, can also inhibit meridian plane height that it is made not extend.Therefore, it is possible to strongly inhibit The variation that the flowing to become larger is influenced when the chord-length of the outer circumference end 7b of the fixed blade 7 of quiet fin 8 is larger, can inhibit because of disorder The increase of caused loss, and efficiently return the convolution velocity component of the discharge air-flow at the outer circumference end 7b of fixed blade 7 It is static pressure to receive.

In addition, by the way that by fixed blade 7, in the plane vertical with the rotary shaft 2 of dynamic fin 5, peripheral side is relative to hub side Obliquely it is arranged to the reverse rotation direction of dynamic fin 5, carrys out the discharge air-flow of automatic fin 5 with according to the radius side of fixed blade 7 To position and it is different at the time of pass through.Noise therefore, it is possible to be generated when discharge air-flow being made to pass through fixed blade 7 is staggered, energy Enough reduce passes through the size of the noise generated when quiet fin 8.

In addition, the defined gap between the outer circumference end and oral area 9 of the rotating vane 4 of dynamic fin 5, from most small diameter portion 9x to Discharge side opening portion 9y goes and expands, and the axis direction position of the up-front outer circumference end of the fixed blade of quiet fin 87 is arranged At between the most small diameter portion 9x of oral area 9 and discharge side opening portion 9y.By adopting such structure, making driven fin 5 Peripheral side to the region of outer circumference end the big discharge air-flow of convolution direction ingredient switch to being gone to discharge side opening portion 9y and Before the air-flow (air-flow with radial direction ingredient) extended in the radial direction, the wing of fixed blade 7 can be enabled its flow into Between piece.Therefore, it is possible to circle round, ingredient big discharge air-flow forced in direction is converted to axis direction ingredient, can be effective as quiet Push back receipts.

In addition, when the strong air-flow of the convolution direction ingredient near the outer circumference end 7b of the fixed blade 7 of quiet fin 8 is all strong System is when being converted to axis direction ingredient, the air-flow of the sides rear 7d near the outer circumference end 7b of fixed blade 7 with from quiet fin 8 Contracting stream is generated between the air-flow of peripheral side, the sides rear 7d near the outer circumference end 7b of fixed blade 7, generation is not converted into quiet The air-flow of pressure.But in present embodiment, between the outer circumference end and oral area 9 of the sides leading edge 7c of the fixed blade 7 of quiet fin 8 Gap S as defined in setting, so leakage stream intentionally can slightly be generated from the pressure surface side of leading edge 7c to negative pressure surface side.By This, is difficult to generate contracting stream in the sides rear 7d of outer circumference end 7b, can be effective as static pressure recycling.In addition, the pressure from the S of gap Leakage stream from power surface side to the pettiness of suction side can along the discharge side of oral area 9 widened discharge side opening portion 9y glibly Slow down, so flow losses will not increase.

In addition, the fin end generated near the outer circumference end of rotating vane 4 flows to downstream side, from fixed blade 7 It is generated when peripheral side is collided with extension 12 disorderly.But in the present embodiment, quiet fin 8 by only fixed blade 7 periphery The extended extension in the sides rear 7d 12 of 7b is held to be fixed on supporting frame 11, the sides leading edge 7c of fixed blade 7 are not fixed in bearing Frame 11.That is, extension 12 is made to be located at the rear side of fixed blade 7.Therefore, in the sides leading edge 7c of fixed blade 7, it can reduce and prolong The disorder of air-flow at long portion 12.

In addition, it is same as the effect of fixed blade 7 of above-mentioned oral area 9, in the sides leading edge 7c of the fixed blade 7 of quiet fin 8 Outer circumference end and supporting frame 11 between be arranged as defined in gap T, so can be intentionally from up-front pressure surface side to suction surface Side slightly generates leakage stream.It is difficult to generate contracting stream in the sides rear 7d of outer circumference end 7b as a result, static pressure can be effective as and returned It receives.In addition, from the pressure face side of gap T to the leakage stream of the pettiness of suction side, it can be along the widened row of discharge side of oral area 9 Go out side opening portion 9y glibly to slow down, so flow losses will not increase.

In addition, a face of extension 12, as shown in figure 5, by curvature shape identical with the recess portion of the circular arc of fixed blade 7 At so not confusing the air-flow of the sides rear 7d of fixed blade 7 as far as possible, capable of effectively recycling static pressure.

As described above, in the present embodiment, can reduce when quiet fin 8 is supported on the shell for keeping oral area 9 because of branch The loss of air-flow caused by holding, so the efficiency that the static pressure at quiet fin 8 recycles can be inhibited to reduce as far as possible.

In addition, the thickness of extension 12 is identical as the thickness of fixed blade 7 in the extension sides rear 12a, more forward edge side It goes more to thicken, so can be with the direction one of the air-flow of the extension leading edge 12b sidewinds direction large variation in extension 12 It causes, inhibits the flow losses caused by stripping as far as possible in the downstream side of extension 12, it can be ensured that in order to be kept fixed leaf 7 required intensity of piece.

In addition, fixed blade 7 becomes the position of the radial direction of peripheral side compared with the discharge side opening portion 9y with oral area 9 It is supported, so foot 13 can be disposed along to the outside of the air-flow of the discharge side opening portion 9y flowings of oral area 9, can be dropped The resistance of the discharge side of low oral area 9.

In addition, fixed blade 7 by the rear end of fixed blade 7 compared with supporting frame 11 to blowout side it is outstanding in a manner of propped up It holds, so foot 13 can be disposed along to the outside of the air-flow of the discharge side opening portion 9y flowings of oral area 9, mouth can be reduced The resistance of the discharge side in portion 9.

Moreover, in the face portion 21a of shell 21 to cover from face portion 21a forward faces (discharge side) quiet fin outstanding 8 mode is provided with blowout grid 25.Blowout grid 25 is supported in the position for more becoming peripheral side compared with supporting frame 11.Separately Outside, blowout grid 25 can be held in shell 21, can also be held in supporting frame 11.

The indoor unit and heat pump water heater of such outdoor unit and the air conditioner with indoor heat exchanger Unit connection, thus constitute refrigeration cycle.Moreover, logical be sent to outdoor heat by the air around outdoor unit by wind turbine 1 Exchanger 23 makes action and the refrigerant of the heat transfer Bottomhole pressure in outdoor heat exchanger 23 by compressor 22 carry out hot friendship It changes.

In the outdoor unit that such as above mode is constituted, the fixed blade 7 and blowout grid 25 of quiet fin 8 be not directly solid It is fixed, and be each secured to shell 21, so even if because falling or applying to blowout grid 25 from positive artificial pressure External force, the external force are absorbed to a certain degree also by the deformation of the face portion 21a of shell 21, so occurring without quiet fin 8 The problem of deformation or the fixed blade 7 of quiet fin 8 and the position relationship of oral area 9 are staggered.It therefore, there is no need to increase blowout grid 25 Intensity, can inexpensively constitute outdoor unit.

In addition, the fixed blade 7 and blowout grid 25 of quiet fin 8 can be separately formed, fixed so molding can be improved Formed precision when blade 7 can manufacture the quiet fin 8 that inexpensively can effectively recycle static pressure.Such as by 7 He of fixed blade When blowout grid 25 is integrally formed, the fin of the position setting undercutting elimination intersected in fixed blade 7 and blowout grid 25 is needed.

Here, undercutting refer in forming from mold take out formed products (demoulding) when only in the direction for opening mold On the shape that can not demould, being can not in the mold only opened in the up-down direction when being not provided with the fin for eliminating the problem It is manufactured, needs that the slide cores (side core) slided in transverse direction are arranged, die cost becomes expensive, the shape that manufacturing cost is got higher Shape.

But in the present embodiment, the fin of such undercutting elimination need not be set, so can inhibit because solid Performance deterioration when fixed blade 7 is arranged fin and quiet fin 8 is caused to recycle static pressure.

In addition, the outdoor unit for being mounted with wind turbine of present embodiment, can not be the room of front blowing-type as Fig. 6 Outer unit can be the outdoor unit of blowing-type above.

Fig. 7 is the longitudinal section of the outdoor unit for being mounted with the upper surface of wind turbine blowout form of present embodiment.The room of Fig. 7 Outer unit only difference is that the direction of the blow out air of wind turbine 1 is the upper table from shell 21 with outdoor unit illustrated in fig. 6 The direction of facial 21b blowout, it is other using with front blowing-type illustrated in fig. 6 the case where identical structure, effect, so province Slightly illustrate.

In addition, in present embodiment, the fixed blade 7 of quiet fin 8 is fixed in oral area 9 or shell by supporting frame 11 Body.Therefore, even if can be kept if blowing out grid 25 and quiet fin 8 in the case where being pressed equal on the direction for moving fin 5 The defined gap between grid 25, quiet fin 8 and dynamic fin 5 is blown out, the fixed blade 7 of quiet fin 8 and the dynamic wing can be prevented Piece 5 contacts and dynamic fin 5 and the deformation of quiet fin 8 or damaged.

(the 3rd embodiment)

Hereinafter, being illustrated to the wind turbine of the 3rd embodiment of the present invention with reference to attached drawing.In addition, the present invention is not by this A little embodiments limit.

For description of the present embodiment, pair with the 1st embodiment of the present invention or the 2nd embodiment phase of the present invention Same inscape marks identical reference numeral, omits the description.

It the following describes only the difference of the 2nd embodiment of present embodiment, the 1st embodiment of the present invention and the present invention Point.

As shown in Figure 10, the leading edge 7c of fixed blade 7 is configured to become upstream side compared with the rear 7d of fixed blade 7. Therefore, in the case of wind turbine 1 in terms of discharge side, in the region compared with anchor hub 6 on the right side, the leading edge of fixed blade 7 7c is located above compared with rear 7d, is being leaned in the region in left side compared with anchor hub 6, the leading edge 7c and rear of fixed blade 7 7d, which is compared, is located at lower section.That is, in the region compared with anchor hub 6 on the right side, fixed blade 7 from weather side alee side under It tilts, is being leaned in the region in left side compared with anchor hub 6, fixed blade 7 is tilted from weather side alee side whereabouts.

In addition, it is shown in Fig. 1 compared with rotary shaft 2 by substantially downside region in, 7 leading edge 7c of fixed blade or after The outer circumference end 7b of edge 7d is located at lower section compared with the anchor hub side 7a of same fixed blade 7.In addition, as described later, fixed leaf The outer circumference end 7b of piece 7 is arranged to be located at the reverse rotation direction (offset) of dynamic fin 5 compared with the 7a of anchor hub side.Therefore, fixed The outer circumference end 7b of the leading edge 7c or rear 7d of blade 7 are underlying compared with the anchor hub side 7a of same fixed blade 7 Region, being added with the height in rotary shaft 2, which makes the height at a distance from outer circumference end 7b offsets compare, becomes downside.

As shown in Figure 10,11 fixed blades 7 are made of whole same shapes.But the direction of rotation of driven fin 5 is It sees, is being leaned in the region in left side compared with anchor hub 6, fixed blade 7 is each other every (spacing) ratio and fixation clockwise Hub 6 is big compared to region on the right side.

In more detail, it is to see clockwise with the direction of rotation of driven fin 5, left side is being leaned on compared with anchor hub 6 In upper and lower directions center region (the region X1 enclosed by the dotted line in Figure 10) in, fixed blade 7 each other every ( Away from) larger, in other regions, the mode for identical interval (equidistant) is provided with 11 fixed blades 7.

The spacing of the fixed blade 7 of access areas X1 is 3 times of the spacing of the fixed blade 7 in other regions.I.e., it is assumed that Be arranged the region other than the X1 of region fixed blade 7 equidistantly region X1 configure fixed blade 7 when, in region, X1 matches It is equipped with 2 fixed blades 7.

The edge of the suction side of fixed blade 7, that is, leading edge 7c, from the anchor hub side 7a at the end as 6 side of anchor hub to conduct The outer circumference end 7b at the end of peripheral side is linearly constituted.In addition, the edge of the discharge side of fixed blade 7, that is, rear 7d, from anchor hub side 7a is held to be constituted to as outer circumference end 7b curve-likes.Moreover, rear 7d forms recess on the direction of leading edge 7c in central portion 7m Curve-like.

In quiet fin 8 shown in FIG. 1 with anchor hub 6 and fixed blade 7, in multiple fixed blades 7, leading edge 7c with Rear 7d is compared is located at the region being below compared with the 7a of anchor hub side positioned at least part of lower section and outer circumference end 7b The fixed blade 7 of (the dotted line area encompassed X2 in Fig. 2), the outer circumference end 7b setting of fixed blade 7 with same fixed leaf The central portion 7m of piece 7 is compared to position on the lower.

That is, in multiple fixed blades 7, leading edge 7c be located at least one of lower section and outer circumference end 7b compared with rear 7d Point be located at the fixed blade 7 in region (the region X2 of Fig. 2) being below compared with the 7a of anchor hub side, leading edge 7c or after Edge 7d does not have the part (horizontal part) with ground level.

In addition, will above in other words, quiet fin 8 is constituted as follows：Assuming that be set with the region other than the X1 of region The fixed blade 7 set equidistantly when region X1 configures fixed blade 7, becomes at least the one of the central portion 7m of fixed blade 7 The part state that underlying fixed blade 7 removes compared with the outer circumference end 7b of same fixed blade 7.

In addition, as shown in Figure 10, length (the half of extension 12 that extension 12 connects fixed blade 7 and supporting frame 11 Diameter direction length) it is different according to the position of installation fixed blade 7.Positioned at the fixed blade 7 up and down of gravity direction Extension 12 is shorter, and the extension for being located at the fixed blade 7 of other positions is longer.Thereby, it is possible to it is easy to ensure that quiet fin 8 is protected It is held in the sufficient intensity of supporting frame 11.

As described above, in the wind turbine of present embodiment, quiet fin 8, the leading edge 7c of fixed blade 7 is located at compared with rear 7d The spacing of fixed blade 7 at the region (region for leaning on left side compared with anchor hub 6 in Fig. 10) of lower section, is more than fixed blade Consolidating at the region (region compared with anchor hub 6 on the right side in Fig. 10) that 7 leading edge 7c is located above compared with rear 7d The spacing of fixed blade 7.

Therefore, it is possible to reduce the region for being provided with fixed blade 7 in a manner of water flowing on the direction of dynamic fin 5, production The case where raw fixed blade 7 is horizontal part.Thereby, it is possible to prevent from being deposited on the snow on the top of wind turbine 1 and its circumferential component Etc. melting, the water of the horizontal part of fixed blade 7 is accumulated in as icicle the case where dynamic 5 side of fin is grown.Therefore, without icicle It is interfered with dynamic fin, generates the damaged problem that abnormal sound or dynamic fin stop.

Moreover, in multiple fixed blades 7, leading edge 7c be located at least the one of lower section and outer circumference end 7b compared with rear 7d Part with the 7a of anchor hub side compared in underlying fixed blade 7, the outer circumference end 7b of fixed blade 7 be arranged with it is same solid The central portion 7m of fixed blade 7 is compared to position on the lower.Alternatively, being not provided in such fixed blade 7, central portion 7m extremely Few part fixed blade underlying compared with the outer circumference end 7b of same fixed blade 7.

Therefore, leading edge 7c is located at lower section and at least part and anchor hub side 7a of outer circumference end 7b compared with rear 7d Compared to underlying fixed blade 7, there is no horizontal part in leading edge 7c or rear 7d.Thereby, it is possible to prevent from being deposited on wind turbine 1 And its snow etc. on the top of circumferential component melts, and is accumulated in the horizontal part of fixed blade 7, generates icicle or icicle growth.

For this point, it is further described using Figure 11.Figure 11 is in order to be compared with present embodiment, in region X1 also configures the wind turbine constituted on 7 ground of fixed blade of the identical diameter shape of the fixed blade 7 in other regions with configuration.

The direction of rotation of dynamic fin 5 from discharge side regard as be clockwise when Figure 11 wind turbine in the case of, quiet fin Fixed blade 7 in, compared with anchor hub 6 be in right side part, from weather side, alee side tilts down with going, even if Water droplet is fallen from above, and is not also flowed on the direction of dynamic fin 5.But the part in left side, from weather side, alee side is gone Ground tilts upwards, so the water droplet fallen from above is possible to flow down on the direction of dynamic fin 5.

Moreover, the case where the water droplet fallen above this is snowmelt etc., it is possible to not only be flowed on fixed blade 7 Windward side, i.e. dynamic 5 direction of fin, and grown as icicle, it is interfered with dynamic fin 5, generates abnormal sound or the dynamic wing Piece 5 stop and it is damaged.

In fig. 11, water droplet in the water droplet fallen from above, being flowed down on the direction of dynamic fin 5 is to be difficult to flow to admittedly The water droplet of the left and right directions (directions outer circumference end 7b or the anchor hub side directions 7a) of fixed blade 7.Such water droplet, in fixed leaf The leading edge 7c of piece 7 is horizontal part (leading edge horizontal part 7e) or rear 7d is that horizontal part (rear horizontal part 7f) is notable It generates.

Moreover, such horizontal part, fixed blade 7 leading edge 7c or rear 7d it is generally horizontal, or from discharge Side see it is curvilinear in the case of easy to produce.In particular, the leading edge 7c or rear 7d of fixed blade 7 are in song in terms of discharge side Threadiness is different according to the position of the radial direction of fixed blade 7 in the blade angle θ of such as above-mentioned mode fixed blade 7 Ground easy tos produce in the case of constituting.

But in present embodiment, as shown in Figure 10, what the leading edge 7c of fixed blade 7 was below compared with rear 7d The spacing of the fixed blade 7 in region is larger, so compared with the quiet fin of the structure of Figure 11, can reduce in the side of dynamic fin 5 The fixed blade 7 of the upward runny state setting of the water capacity has the case where becoming horizontal part.

Moreover, the leading edge 7c or rear 7d of the fixed blade 7 in left side do not have horizontal part compared with anchor hub 6, So water droplet does not flow stagnantly in the lateral direction, so the icicle gone to dynamic fin 5 is not grown.

In particular, in fixed blade 7, leading edge 7c is formed as curve-like and leading edge 7c be located at compared with rear 7d lower section, And at least part of outer circumference end 7b underlying fixed blade compared with the 7a of anchor hub side (configures the region X2 in Figure 10 Fixed blade) in, the outer circumference end 7b of fixed blade is arranged below compared with central portion 7m, thus can eliminate water droplet be easy The horizontal part stockpiled.

In addition, from the quiet fin of the structure of Figure 11 remove with anchor hub 6 compared with positioned at left side, with leading edge horizontal part 7e Or except 2 fixed blades 7 of rear horizontal part 7f, as shown in Figure 10, it is configured in the quiet fin 8 of 11 fixed blades 7, There is no icicle to be grown up in the side of dynamic fin 5, interfered with dynamic fin 5, generates abnormal sound or dynamic fin 5 stops Or damaged problem.Moreover, make the number of fixed blade possessed by quiet fin 8 is reduced to minimum limit, can will recycle The effect of the static pressure of quiet fin 8 is maintained maximum.

In addition, being not only not provided with fixed blade 7 in region X1, it is also not provided with extension 12 and foot 13, so without water What drop was accumulated in extension 12 and foot 13 becomes horizontal part, become ice lead to the problem of and the starting point of growth.

In addition, in present embodiment, 2 fixed blades 7 are removed from the quiet fin of the structure of Figure 11, are made and 6 phase of anchor hub Spacing than the fixed blade 7 in the region by left side differs, and thus increases spacing.But not limited to this, as long as with anchor hub 6 Compared to the spacing that the spacing in the region by left side is more than the region compared with anchor hub 6 on the right side, it will be able to make and 6 phase of anchor hub Than being equidistant by the region in left side.In addition, in the case that compared with anchor hub 6 lean on left side region be also it is equidistant, it is excellent It selects and is designed to make quiet fin 8 integrally slightly to rotate, become the configuration for the fixed blade for not generating horizontal part.

In addition, in present embodiment, it is linear to make the leading edge 7c of fixed blade 7, and it is curve-like to make rear 7d, but from It is not provided with water droplet to be easy from the perspective of the position stockpiled, it is curve-like that can also make leading edge 7c, and rear 7d is linear.

Moreover, in the outdoor unit for the wind turbine for being mounted with present embodiment, the square upward water flow in dynamic fin 5 can be prevented The fixed blade 7 of lower such shape has horizontal part.Therefore, it is possible to prevent the snow etc. on the top for being deposited on outdoor unit from melting Solution is accumulated in fixed blade 7 or icicle generates or growth.

Moreover, in such outdoor unit, the fixed blade 7 and blowout grid 25 (referring to Fig. 6) of quiet fin 8 are no It directly fixes but is each secured to shell 21, so even if because falling or from positive artificial pressure in blowout grid 25 are applied with external force, which also can to a certain degree be absorbed because of the deformation of the face portion 21a of shell 21, so without the quiet wing The case where piece 8 deforms or the position relationship of the fixed blade 7 of quiet fin 8 and oral area 9 deviates.It therefore, there is no need to increase blowout The intensity of grid 25 can inexpensively constitute outdoor unit.

(the 4th embodiment)

Hereinafter, being described with reference to the wind turbine of the 4th embodiment of the present invention.In addition, the present invention is not implemented by these Mode limits.

For description of the present embodiment, pair with the 1st embodiment of the present invention, the 2nd embodiment of the present invention or The identical inscape of the 3rd embodiment of the present invention, marks same reference numeral and omits the description.

It the following describes only the 1st embodiment of present embodiment and the present invention, the 2nd embodiment of the present invention or sheet Different point in 3rd embodiment of invention.

Figure 12 is the front view in terms of the slave discharge side of the wind turbine of the 4th embodiment of the present invention.In addition, in present embodiment In, pair inscape identical with another embodiment marks same reference numeral and omits the description.

As shown in figure 8, the discharge side (downstream side) in dynamic fin 5 is provided with quiet fin 8, which has anchor hub 6 And 12 fixed blades 7 being arranged around anchor hub 6.Quiet fin 8 is clockwise side in the direction of rotation of dynamic fin 5 Left side is being leaned on compared with rotary shaft 2 (referring to Fig. 1) and is being in the region in center of upper and lower directions, fixed blade 7 to seeing Spacing be 2 times of spacing of fixed blade 7 of other regions.I.e., it is assumed that when equidistantly to configure the fixation leaf of same shape When piece 7, is seen for clockwise direction in the direction of rotation of driven fin 5 and leaning on left side compared with rotary shaft 2 and be in upper and lower To center region be configured with 1 fixed blade 7.

In addition, being that clockwise direction sees that the region by left side compared with anchor hub 6 is set in the direction of rotation of driven fin 5 The shape for the fixed blade 27 set, with being arranged, the shape in the fixed blade 7 in the region compared with anchor hub 6 on the right side is different.

Variform fixed blade 27 is following blade：Assuming that when the fixed blade 7 of same shape is equidistantly configured, At least part of the central portion 7m of fixed blade is located at lower section compared with the outer circumference end 7b of fixed blade.Moreover, fixed blade 27 is are not provided with the shape of horizontal part from the central portion 27m of fixed blade to outer circumference end 7b.

In more detail, the shape between the central portion 27m of fixed blade 27 and anchor hub side 27a is to be fixed with other 7 identical shape of blade, the shape between central portion 27m and outer circumference end 27b are different.It is fixed in the rear 27d of fixed blade 27 It is configured to curve-like between the central portion 27m and anchor hub side 27a of blade 27, but between central portion 27m and outer circumference end 27b In be formed as linear.

In addition, meridian plane height h2 (the following ginsengs of the meridian plane height h2 of fixed blade 27 and other 11 fixed blades 7 According to Fig. 1) it is identical, it is certain from anchor hub side 27a to outer circumference end 27b.In addition, fixed blade 27 blade angle θ (with Lower reference Fig. 3 A, Fig. 3 B) it is identical as the blade angle θ of other 11 fixed blades 7, make the outer circumferential side compared with central portion 27m The blade angle θ b of the sides 27b are held to be more than the blade angle θ a for leaning on the anchor hub side sides 27a compared with central portion 27m.

Therefore, the leading edge 27c of fixed blade 27, between the central portion 27m and anchor hub side 27a of fixed blade 27 with Other 11 fixed blades 7 equally constitute to be linear, but between central portion 27m and outer circumference end 27b in be formed as curve-like.
