Description
Technical field
The present invention relates to the technical fields of renewable new energy wind electricity blade, refer in particular to a kind of pre-buried spiral shell of wind electricity blade
Set.
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 that is, 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 mode 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
It is an object of the invention to overcome the deficiencies in the prior art, it is proposed that a kind of wind electricity blade built-in turnbuckle, it can be most
The length of bigization blade root built-in turnbuckle and anti-pulling ability.
To achieve the above object, technical solution provided by the present invention is：A kind of wind electricity blade built-in turnbuckle includes
One sleeve and second sleeve, first sleeve and second sleeve are connected, in advance by force using interference fit by way of hydraulic pressure
An entirety is formed, when being bolted, bolt is threadedly connected at second sleeve across the first sleeve；Described first
The inside of sleeve is formed with the first passage passed through for bolt, and the inside of the second sleeve is formed with threaded second and leads to
Road, the first passage are connected with second channel, and the second channel, which is divided to, different two sections, wherein one section is not threaded
Stepped section, another section is bolted section to be threaded, and the stepped section is located at first passage and is bolted section
Between.
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 for 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.
Compared with prior art, the present invention having the following advantages that and advantageous effect：
1st, the present invention provides a kind of Feasibility Solution for longer wind electricity blade built-in turnbuckle, passes through segmental machining spiral shell
Set overcomes the processing limitation of lathe.
2nd, the present invention is improves the pulling capacity that single built-in turnbuckle can be born so that identical blade root Lay up design can
To bear the wind load of bigger, the also research and development for the blade of smaller blade root diameter under following same load provide a kind of thinking.
Description of the drawings

Fig. 2 is the connection diagram of built-in turnbuckle of the present invention (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 embodiment
With reference to specific embodiment, the invention will be further described.
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 by force using being interference fitted by way of hydraulic pressure, form 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 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
Upper formation there are two the cavity that is not communicated with, two cavitys be not communicated be in order to prevent in vacuum infusion process into glue, one of them
Cavity is threaded second channel (requirement on machining accuracy is high), another cavity matches for shape size 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, and stepped section 21 is to be located at first passage 11 and be bolted section to be threaded
Between 22, when carrying out bolt 4 and connecting, bolt 4 is to pass sequentially through to be connected to after first passage 11, stepped section 21 to be bolted
Section 22, in this way after pretightning force is applied, 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.
It 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 embodiments of the invention, and the implementation model of the present invention is not limited with this
It encloses, therefore the variation that all shape, principles according to the present invention are made, it should all cover within the scope of the present invention.
