It is yawed to wind structure, first embodiment as shown in Figure 1 the utility model proposes a kind of, including：Tower is (in figure not
Indicate), the fixed gear ring 1 that is connected in the tower and the generator nacelle 2 to wind can be yawed around tower；Fixed gear ring 1
Set on 2 lower section of generator nacelle and generator nacelle 2 is supported by upper sliding shim 31；The center of gravity of generator nacelle 2 is in level
The projection in face is located at except fixed gear ring 1.
Therefore when replacing with sliding shim 31, only need to lift generator nacelle 2 can remove sliding shim 31.In conjunction with Fig. 3
It is shown, since the position of centre of gravity A of generator nacelle 1 is located in the projection of horizontal plane except fixed gear ring 1, therefore, it generates electricity when unclamping
When fixation kit 5 of the cabin body 2 far from the sides its position of centre of gravity A, the i.e. liftable generator bay body 2 of the power of very little is only needed, or
When unclamping fixation kit 5 of the generator nacelle 2 far from the sides its position of centre of gravity A, generator nacelle 2 can be in the gravity power of itself
The lower nature of square effect rises；Compared to the existing yaw that must use large scale equipment that could jack up for wind structure, this reality
The cost of sliding shim 31 is replaced with novel enormously simplify.
As shown in Fig. 2, the utility model also proposes another embodiment：Several cards are offered on the end face of fixed gear ring 1
Slot 11, upper sliding shim 31 are removable installed in card slot 11.Existing upper sliding shim 31 is generally fixed by bolts, hair
The needs of motor nacelle 2 are lifted to very high position and could remove bolt for fixing with tool, cause with bolt it is fixed on
The replacement of sliding shim 31 is especially difficult.Upper sliding shim 31 in the present embodiment is not using fixation kits such as existing bolts
Be fixed, meanwhile, in conjunction with generator nacelle 2 center of gravity except the radius of fixed gear ring 1 the characteristics of, it can be achieved that not outer
In the case of portion's power source device, you can lifting generator nacelle 2 makes its tail portion upwarp smaller height, you can to take out and fix
It is located at the upper sliding shim 31 of tail portion on gear ring 1.The process that the technical solution of the utility model non-bolt is replaced so that upper sliding
The replacement process of gasket 31 is simply, conveniently.
Certainly, the upper sliding shim 31 also can be it is existing a variety of dismountable connection structures such as clamp, clamp, without
It is limited to the card slot 11 described in Fig. 2.
The utility model also proposes another embodiment：With reference to shown in Fig. 4, radial symmetric of the card slot 11 about fixed gear ring 1
Distribution；Since generator nacelle head is equipped with wind wheel and blade, therefore the center of gravity of generator nacelle replaces with cunning generally proximate to head
It when mobile gasket 31, can yaw manually, upper sliding shim 31 to be replaced is gone to the tail portion of generator nacelle 2, unclamps again power generation
The clamp of cabin body tail portion, you can make generator nacelle tail portion lift naturally or i.e. liftable with smaller power, to replace
Upper sliding shim 31 below tail portion.At this point, radially the upper sliding shim 31 in other card slots 11 can still play reduction sliding
The effect of friction does not influence to yaw the process to wind.The size and spacing of its radially-arranged upper sliding shim 31 can be according to tools
Body situation is set.
To improve the fixed effect of upper sliding shim 31, the utility model proposes another embodiments：Card slot 11 includes upper slot
Mouthful and inner cavity, the upper notch on 1 end face of fixed gear ring projection be located at projection of the inner cavity on 1 end face of fixed gear ring it
Interior, i.e., the upper notch edges of card slot 11 are equipped with the lateral protrusion of diagram in the plane parallel with 1 end face of fixed gear ring, so that
Card slot 11 forms structure small for mouth and large for cavity, and the protrusion can prevent sliding shim 31 from axially deviating from from card slot 11, causes partially
Boat dyskinesia.The upper notch shape of the card slot 11 can be strip, be opened being formed close to the direction of 1 central shaft of fixed gear ring
The side channel mouth of formula is put, upper sliding shim 31 can be packed into from the side channel mouth in card slot 11.Certainly, fixed gear ring 1 also can be such as Fig. 4
Do not include the protrusion shown in embodiment, on card slot 11.
The utility model also proposes another embodiment：Upper sliding shim 3 includes rubbing surface and is connected on the rubbing surface
Fixing piece, the fixing piece is inserted into card slot 11.In conjunction with a upper embodiment, the size of the fixing piece can be with the side channel mouth
Size match, to be packed into；And match with the protrusion of the upper notch so that the protrusion of upper notch can block it is described solid
Determine part.
The yaw of the utility model may also include deviation drive device to wind structure, as shown in figure 3, generator nacelle 2 is logical
Several fixing devices 5 are crossed to be fixed on deviation drive device.When yaw is to wind, deviation drive device drives generator nacelle 2
Yaw, makes the blade in generator nacelle 2 farthest keep state windward.Sliding shim 31 is needed replacing, is unclamped solid
Device 5 is determined, so that the tail portion of generator nacelle 2 is lifted；To keep 2 fixed stability of generator nacelle, and lifting power generation
It does not topple when cabin body 2 phenomenon, fixing device 5 should be multiple；When unclamping the fixing device 5 of generator nacelle 2 tail portion more
When changing sliding shim 31, the fixing device 5 of remaining position is still kept fixed state, and generator nacelle 2 is made to be kept fixed, will not
It topples.
A variety of fixation kits such as existing bolt or structure can be used in fixing device 5, also can be clamp.Preferably, fixed
Device 5 is clamp, is fixed on the outside of fixed gear ring 1, so that clamp are in fixed generator nacelle 2, also to upper sliding shim
31 play the role of it is radially fixed, prevent sliding shim 31 from radial direction deviate from.
The deviation drive device further includes yaw sliding bearing, and the yaw sliding bearing is relatively fixed the sliding of gear ring 1,
As shown in Figure 1, it is provided between fixed gear ring 1 radially slides pad 32, between fixed gear ring 1 and the support component of lower part also
Equipped with lower slider pad 33.
As shown in Figure 1, fixed gear ring 1 can be connect by brake 4 with generator nacelle 2.When wind is completed in yaw, system
Dynamic device 4 is engaged with fixed gear ring 1, so that generator nacelle 2 is fixed relative to fixed gear ring 1 and tower.
Based on above each yaw to the embodiment of wind structure, the utility model also proposes a kind of wind power generating set；It is wrapped
The yaw described in aforementioned any one is included to wind structure, also there is advantageous effect of the aforementioned yaw to wind structure.
The above is only some embodiments of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
