Description
Technical field
The present invention relates to a kind of preparation method of the support webs of blade of wind-driven generator, and in particular to a kind of wind electricity blade
Preparation method with flanging web, belongs to wind power generation field.
Background technology
Wind rotor blade of wind generator relies on its special aerodynamic configuration schematic capture wind energy, and is translated into machinery
Can, there is environmental protection.During wind electricity blade is mainly and is made up of two half-shells (being referred to as windward side, lee face)
Empty composite product, its hollow space is supported on blade axial direction by web, therefore web is wind electricity blade product
One of important component.The web of wind electricity blade hollow space is supported to be made up of two parts, respectively leading edge web and trailing edge web.
With bonding flange when web makes, bonding flange is sticked together using bonded adhesives with two housings.Partial blade is needed because of structure
Will, except there is main bonding flange to be also devised with flanging, being used together bonding with main Nian Jie flange is adhesive on housing.
Current Main be by flanging it is prefabricated after be adhesive on web using bonding；Or subregion is pasted using hand
Technique, i.e., can enter blade interior operating area, after web is stained with blade shell when the die is closed, by flanging glass-fiber-fabric in people
Hand is pasted between web outside and blade shell.Both methods need substantial amounts of manpower and materials, and the operating time is long, production efficiency
It is low, for prefabricated rear technique for sticking, on the one hand there is location difficulty, it is difficult to ensure to reach rational bonding gap thickness after bonding
Degree, on the other hand sticked together before both, there is also the quality risk for coming off；For hand paste technique, by paste quality in one's hands
Restriction, resin content control and hand paste bubble control quality directly influence the service life of blade.
Therefore, it is necessary that a kind of technological design is designed on the basis of prior art rationally, easy to operate, work effect
Rate is high, low cost, and flanging can be made to be integrally formed with web main body, can improve web quality and be firmly bonded the wind-powered electricity generation of degree
Preparation method of the blade with flanging web.
The content of the invention
Goal of the invention：The invention aims to solve the deficiencies in the prior art, there is provided a kind of technological design rationally, is grasped
Facilitate, high working efficiency, low cost, flanging can be made to be integrally formed with web main body, web quality and and leaf can be improved
Piece housing is firmly bonded the preparation method of the wind electricity blade with flanging web of degree.
Technical scheme：In order to realize the purpose of the present invention, the technical scheme that the present invention takes is：
A kind of preparation method of wind electricity blade with flanging web, it is comprised the following steps：
A. make with reeded wind electricity blade web mold
According to wind electricity blade web outer surface 3D profiles, web mold is welded after segmented line cutting steel plate, and in web mould
Tool both sides press flute, then welds flange rib, and install section reinforcing plate in the outside of flange rib in groove；
On b, the flange rib that flange layer of cloth is laid in groove, then liner is inserted in groove, make liner complete
Filling groove, makes liner upper surface be flushed with web mold surface；
C and then laying web material of main part and vacuum aided material in welding web mold, irrigate vacuum resin simultaneously solid
The web with flanging is taken out after change.
Preferably, preparation method of the above-described wind electricity blade with flanging web, it is interior described in step b
It is on-deformable silica gel material liner to serve as a contrast.
Preferably, preparation method of the above-described wind electricity blade with flanging web, step c is then in welding
Web material of main part is laid in web mold, the auxiliary material for irrigating resin and curing agent mixture is then laid：It is described
Auxiliary material laying method be：
The flow-guiding screen for irrigating first is laid on web material of main part, then sebific duct is led in laying on flow-guiding screen, and will
Lead sebific duct to be connected with steel wire tube, the helix tube for being vented compacting then be installed in web mold both sides, then lay vacuum tube,
And whole auxiliary material and web mold are covered into parcel with vacuum diaphragm；Then vavuum pump is opened to discharge inner air to form negative
Pressure, resin is entered inside vacuum diaphragm by steel wire tube under the vacuum pressures with curing agent mixture, and is leading sebific duct and flow-guiding screen
Guiding under abundant infiltration material of main part and flange layer of cloth, after resin and curing agent mixture complete curing reaction, take out
To the web with flanging.
Simultaneously be molded for flange layer of cloth and web main cloth by present invention original creation, can save it is prefabricated after be bonded again, or
In the tedious work step of matched moulds defensive position paste, operating efficiency is higher.
Web mold in the present invention, is designed using groove, and flange rib is welded in groove, can be reserved placement and be turned up
The space of side layer of cloth.
Web mold in the present invention is adjustable berth away from web, flange rib is welded in groove, left in groove
Sufficient space, in production process, according to pitch requirements, can adjust the position of welding flange rib；
Liner, the liner are used in the present invention can be filled up completely with groove, and liner upper surface is neat with web mold upper surface
Flat, liner is indeformable after being squeezed, and easily convenient taking-up；On the one hand the liner is used for the fixation of flange layer of cloth, on the one hand will be recessed
Groove fills and leads up the laying for normal web main cloth.
Beneficial effect：Compared to the prior art preparation method of the wind electricity blade with flanging web that the present invention is provided have
Advantages below：
Preparation method of the wind electricity blade with flanging web that the present invention is provided, whole technological design is rationally, easy to operate,
High working efficiency, low cost, flanging can be integrally formed with web main body, can improve web quality and be bonded with blade shell
Firmness, the band flanging Web shape for preparing is similar to " I " shape.
