Description
Technical field
The utility model is related to the technical fields of renewable new energy wind electricity blade, and it is pre-buried to refer in particular to a kind of wind electricity blade
Swivel nut.
Background technology
It is known in the industry, in wind-powered electricity generation industry, usually blade is connected on wheel hub with T-bolt.Another alternative
A series of swivel nuts are embedded to blade root simultaneously during laying and glass fibre one form are used for blade root by case built-in turnbuckle
Connection.The benefit of built-in turnbuckle connection type is can to reduce the attachment force of single connector.The anti-pulling of built-in turnbuckle is advocated
To depend on the surface area of swivel nut.Surface area is bigger and the bonded area of adjacent material is bigger, and the pulling capacity that can be born is got over
Greatly.But under the conditions of same swivel nut diameter, the length limited of swivel nut can not be made long in processing conditions and cost.
Invention content
The purpose of the utility model is to overcome the deficiencies in the prior art, it is proposed that a kind of wind electricity blade built-in turnbuckle, it can
To maximize the length and anti-pulling ability of blade root built-in turnbuckle.
To achieve the above object, technical solution provided by the utility model is：A kind of wind electricity blade built-in turnbuckle, including
There are the first sleeve and second sleeve, first sleeve and second sleeve to connect by force by way of hydraulic pressure using interference fit
It connects, constitutes an entirety in advance, when being bolted, bolt is threadedly connected at second sleeve across the first sleeve；Institute
The inside for stating the first sleeve is formed with the first passage passed through for bolt, and the inside of the second sleeve is formed with threaded
Two channels, the first passage are connected with second channel, and the second channel, which is divided to, different two sections, wherein one section for without
The stepped section of screw thread, another section is bolted section to be threaded, and the stepped section is located at first passage and bolt connects
It connects between section.
The wind electricity blade built-in turnbuckle further includes the taper pipe there are one built-in filler, and the second sleeve is grown at it
Formed on degree direction there are two the cavity that is not communicated with, one of cavity is second channel, another cavity be shape size with
The installation position that taper pipe matches, the taper pipe are plugged at the installation position, are an entirety admittedly with second sleeve.
Filler in the taper pipe is PVC.
First sleeve and second sleeve are round buss.
First sleeve and second sleeve are 42CrMoA sleeves.
The taper pipe is iron chock.
The utility model compared with prior art, has the following advantages that and advantageous effect：
1, the utility model provides a kind of Feasibility Solution for longer wind electricity blade built-in turnbuckle, is added by segmentation
Work swivel nut overcomes the processing limitation of lathe.
2, the utility model is the pulling capacity that improves single built-in turnbuckle and can bear so that identical blade root laying is set
Meter can bear the wind load of bigger, and the also research and development for the blade of smaller blade root diameter under the following same load provide a kind of think of
Road.

Fig. 2 is the connection diagram of built-in turnbuckle described in the utility model (without taper pipe) and bolt.
Fig. 3 is the sectional view of second sleeve.
Fig. 4 is the stereogram of taper pipe.
Fig. 5 is the sectional view of taper pipe.
Specific implementation mode
With reference to specific embodiment, the utility model is described in further detail.
As shown in Figures 1 to 5, the wind electricity blade built-in turnbuckle that the present embodiment is provided includes the first sleeve 1, second
Sleeve 2 and the taper pipe 3 (material is iron) of a built-in filler 6 (preferably PVC), first sleeve 1 and second sleeve 2 are equal
For round buss, material 42CrMoA, surface is using inside and outside the dacroment process/Dlata tone+Dlata seal processing come anti-corrosion
Erosion, first sleeve 1 and second sleeve 2 are connected using interference fit by way of hydraulic pressure by force, constitute an entirety in advance,
The long high processing costs of length sleeve can be solved the problem of in this way, because sleeve is long to need long drill bit, one has shake
The problem of cause machining accuracy low, two come drilling machine input cost it is high, sleeve, which is divided into two sections of processing, can solve problem above；
The inside of first sleeve 1 is formed with the first passage 11 (not threaded) passed through for bolt 4, and second sleeve 2 is in its length direction
There are two the cavity that is not communicated with, two cavitys, which are not communicated with, is in order to prevent in vacuum infusion process into glue for upper formation, one of them
Cavity is threaded second channel (requirement on machining accuracy is high), another cavity is what shape size matched with taper pipe 3
Installation position 23 (requirement on machining accuracy is low), taper pipe 3 are plugged at the installation position 23, are admittedly an entirety with second sleeve 2, are adopted
It is exactly pre- in order to can effectively be reduced while ensuring 2 intensity of second sleeve with the mode that second sleeve 2 is combined with taper pipe 3
Bury the weight of swivel nut；In addition, first passage 11 is connected with second channel, second channel, which is divided to, different two sections, wherein one section
For not threaded stepped section 21, (sectional area reduction) is gradually reduced by rigidity to reduce the stress collection of swivel nut rest position
Middle problem, another section is bolted section 22 to be threaded, and stepped section 21 is to be located at first passage 11 and be bolted section
Between 22, when carrying out the connection of bolt 4, bolt 4 is to be connected to be bolted after passing sequentially through first passage 11, stepped section 21
Section 22, in this way after applying pretightning force, pretightning force can lead to formation press-in connection between two sleeves and inseparable, solve
The shortcomings that general sleeve ensures to connect only by the connection that interference fit is formed only by frictional force.
In use, can embedded in glass steel 5 after the first sleeve 1 and second sleeve 2 (having inserted taper pipe 3) interference fit
In, final and fiberglass 5 forms root of blade, and root of blade is connected by bolt 4 with the wheel hub of unit.
The examples of implementation of the above are only the preferred embodiment of the utility model, not limit the utility model with this
Practical range, therefore change made by all shapes according to the utility model, principle, it should all cover in the scope of protection of the utility model
It is interior.
