The structure of individual example is similar to first example.Difference is, as shown in figure 5, the wedge-shaped part 32 in first example
Inclined-plane can be substituted by the curved surface of an indent to form the 3rd example；Or, as shown in fig. 6, in first example
The surface that can also mutually be spliced by a curved surface and plane of inclined-plane of wedge-shaped part 32 substitute to form the 4th example, other knots
Structure will not be described here.
In the present embodiment, the second spliceosome 4 can have numerous embodiments, illustrated below：
Fig. 8 is the structural representation of first example of the second spliceosome 4 in Fig. 1.As shown in figure 8, the second spliceosome 4 is
Cylindrical-shaped structure, the end face of the cylindrical-shaped structure is inclined-plane, the structure that concretely a cylinder is formed after cutting sth. askew；
Fig. 9 is the structural representation of second example of the second spliceosome 4 in Fig. 1.As shown in figure 9, the second spliceosome 4 is
Ladder structure of right angle.
In the present embodiment, as the second spliceosome 4 needs to mate with the recess 31 of the first spliceosome 3.Therefore, first
Each example of spliceosome 3 can not need, with each example independent assortment of the second spliceosome 4, select to be mutually matched first
Spliceosome 3 and the second spliceosome 4, for example, first example of the first spliceosome 3, the 3rd example and the 4th example
Mate with first example of the second spliceosome 4, second example of the first spliceosome 3 can be with second of the second spliceosome 4
Example is mated.
It should be noted that when the second spliceosome 4 shown in Fig. 7 is adopted, glass can be wrapped up on 4 surface of the second spliceosome
Fiber cloth, can prevent the second spliceosome 4 from loosening.
In the present embodiment, the first spliceosome 3 and the second spliceosome 4 can all adopt PET, PVC, timber or bamboo etc.
Light material, while being filled with and fix, is conducive to mitigating weight, reduces cost.
In the present embodiment, bolt sleeve component 2 may include bolt sleeve 21 and glass layer 22, and bolt sleeve 21 includes set
Body 211, first boss 212 and multiple second boss 213, female thread 201 is formed in bolt sleeve 21.
First boss 212 is formed on the side of body 211 one end away from the second spliceosome 4, multiple second boss 213
Being spaced along the direction away from first boss 211 successively and be formed on the side of body 211, i.e., multi-turn is formed on body 211 convex
Platform, and second boss 213 is less than first boss 211.
Glass layer 22 coat and 21 side of bolt sleeve of fitting on region in addition to 212 outer rim of first boss, and glass
22 outer surface of glass fibrous layer is concordant with 212 outer rim of first boss, and bolt sleeve 21 can do blasting treatment, improves surface roughness, makes
Bolt sleeve 21 is more firm with what glass layer 22 was combined, desirably prevents to extract.So as to being made by glass layer 22
Bolt sleeve 21 is more consolidated, and as first boss 211 is located at one end of the second spliceosome of distance 4, i.e., away from wind electricity blade top
The one end in portion, the end face of first boss 211 is located at the root structure outermost of the wind electricity blade.Therefore, glass layer is made
22 coat and 21 side of bolt sleeve of fitting on region in addition to 212 outer rim of first boss, glass layer 22 can be prevented complete
In body 1, it is to avoid expose, the part for preventing glass layer 22 from exposing tilts or damages and cause 22 quilt of glass layer
Haul out or damage.
In the present embodiment, the structure of glass layer 22 also has multiple, but is not limited, for example：Glass can be adopted
Glass fiber cloth covers the region on parcel 21 side of bolt sleeve in addition to 212 outer rim of first boss, fills up between second boss 213
Space, and make 2 outer surface of glass fabric concordant with 212 outer rim of first boss；Also glass fibre can be utilized using moulding process
Material directly forms glass layer 21 on bolt sleeve 21；Or can also adopt glass fibre material rove, by
The rove is wound on bolt sleeve 21 forms glass layer 21.As the cost of rove is relatively low and simple to operate, and be conducive to
Fit tightly with bolt sleeve, be difficult the presence of gap, therefore, glass layer 22 can be formed by the rove of the glass fibre for winding.
In the present embodiment, the second boss 23 on bolt sleeve 21 has various ways, for example：As Figure 10 and Figure 11 institute
Show, Figure 10 is the structural representation of first example of bolt sleeve in Fig. 1, Figure 11 is the sectional view of the bolt sleeve in Figure 10, the
Two boss 23 can be loop configuration, and the radial section of second boss 23 is trapezoidal.
At least one second boss 23 of bolt sleeve 21 is pyramidal structure, and the small end of pyramidal structure is towards the second spliceosome
4 are arranged, i.e., towards the direction at the top of wind electricity blade, form barb-shaped structure, so as to preventing bolt sleeve 21 from extracting further,
Reliability is improved further.Specifically as shown in Figure 12 and Figure 13, Figure 12 is the structural representation of second example of bolt sleeve in Fig. 1
Figure；Figure 13 is the sectional view of bolt sleeve in Figure 12, and each second boss 23 of bolt sleeve 21 is above-mentioned pyramidal structure；As Figure 14
With shown in Figure 15, Figure 14 is the structural representation of the 3rd example of bolt sleeve in Fig. 1；Figure 15 is the section view of bolt sleeve in Figure 14
Figure；21 part second boss 23 of bolt sleeve is the first of above-mentioned pyramidal structure, another part second boss 23 and bolt sleeve 21
Second boss 23 in individual example is identical.
In the present embodiment, bolt sleeve 21 is enclosed construction, specifically can be blocked up by welding near 4 one end of the second spliceosome
Head, pre- sunk screw, are sealed using sealing means such as sealing member interference fit, but not limited to this, so as to prevent the tree for irrigating
Fat is entered in bolt sleeve 21 and covers female thread 201, it is to avoid is caused bolt coordinate with bolt sleeve 21, is advantageously ensured that wind-powered electricity generation leaf
The root structure of piece and the normal mounting of wheel hub.
In the present embodiment, the second spliceosome 4 is along multiple radial hole (not shown)s that are radially provided with of body 1, and
Each described radial direction hole shape can all be circular or other shapes, and the purpose of radial hole is to be beneficial to fill using vacuum aborning
Injection formation technology carries out manufacture root of blade.
In the present embodiment, multiple radial holes can array distribution on the second spliceosome 4, for example, multiple described
Radial hole can rectangular array (purpose of radial hole is that convenient production is unrelated with stress).
In the present embodiment, the diameter of multiple radial holes is about 2mm, but is not limited, meanwhile, Duo Gesuo
State radial hole can rectangular array distribution, i.e. multiple radial holes can line up rows and columns, and per a line and per string
In the radial hole, the spacing of the two neighboring radial hole is 20mm.
In the present embodiment, the shape of bolt sleeve 21 and bolt sleeve component 2 can have multiple, but be not limited, example
Such as：Bolt sleeve 21 can square bolt sleeve, bolt sleeve component 2 is also square structure, or bolt sleeve 21 is alternatively circular bolt sleeve,
And bolt sleeve component 2 is cylindrical structural.
But as square bolt sleeve manufacturing process is complex, and in the case of internal diameter identical, square bolt sleeve is compared
More in the materials of circular bolt sleeve so that thus weight is bigger, and square bolt sleeve has corner angle, stressing conditions are multiple everywhere
Miscellaneous, it is difficult to ensure uniform stressed, easy Local Damaged.It is therefore preferable that bolt sleeve 21 is also circular bolt sleeve, and bolt sleeve component
2 is cylindrical structural.
When bolt sleeve 21 is also circular bolt sleeve, and when bolt sleeve component 2 is cylindrical structural, the of the first spliceosome 3
The corresponding preferably arc-shaped surface in the surface of one groove 311, specifically can refer to first example of the first spliceosome 3 and second show
Example, to mate.
As shown in figure 16, Figure 16 is the flow process of one embodiment of manufacture method of the root structure of wind electricity blade of the present invention
