Abstract

A technology for manufacturing the blade of larger wind-driven electric generator includes such steps as spraying demoulding agent onto the moulding surface of mould, coating colloidal film, laying the shell of blade, sequentially spreading demoulding cloth, demoulding film and colloid sucking felt, arranging a vacuumizing spiral tube to surround said layers, wrapping all of them by a film, connecting two ends of said vacuum tube to a vacuum machine, vacuumizing, and solidifying. It can eliminate air bubbles and improve structure strength.

Description

A kind of manufacture method of blades of large-scale wind driven generator
Technical field
The present invention relates to the manufacture method of a kind of wind power plant, particularly a kind of blades of large-scale wind driven generator.
Background technology
In the prior art, because the megawatt level composite material blade of wind-driven generator is very big, the moulding process that the employing hand that has is stuck with paste, but general hand paste technology is to finish after the layer of shop, just waits for curing, can have bubble in the structure.These bubbles are present in this structure, will reduce the intensity and the life-span of blade greatly.Also there is not at present good measure elimination bubble wherein.
Summary of the invention
The technical problem to be solved in the present invention is at the deficiencies in the prior art, has proposed to eliminate the manufacture method of a kind of blades of large-scale wind driven generator of residual bubble in the layer of shop.
The technical problem to be solved in the present invention is achieved through the following technical solutions, and a kind of manufacture method of blades of large-scale wind driven generator is characterized in: at first spray releasing agent on the forming surface of mould, be coated with gel coat; Carry out blade shell then and lay, finish layer back, shop and on blade shell, spread release cloth, mould release film, suction glue felt successively; Inhale vacuum screw pipe at the circle that is provided with of inhaling blade shop, glue felt outer layer all around; With integral coating one deck vacuum film, seal between four limits of vacuum film and the mould and join again; Join inhaling the two ends of vacuum screw pipe and the suction vacuum plant of peripheral hardware, vacuumize then, and hunt leak and mending-leakage; The final curing moulding.
The technical problem to be solved in the present invention can also come further to realize by the following technical programs, blade shell is laid in stacked shop several layers prepreg, described prepreg is that dried glass cloth soaks a kind of material that obtains later through resin, its manufacturing process is at first dried glass cloth to be walked around the roll coater that is located in the steeping vat, again through about behind the plastic squeeze roller on cloth-gathering roller.At dried glass cloth rewinder roll, roll coater, all be provided with some jockey pulleys between plastic squeeze roller, the cloth-gathering roller per two up and down, between roll coater and dried glass cloth rewinder roll, also be provided with the counting running roller.
The present invention is compared with prior art laying covering one deck vacuum film on the blade shop layer that finishes, and this film and blade mold have been formed an airtight system together.Use vavuum pump in this system, to vacuumize then.Spiral vacuum tube and suction glue felt can be distributed in vacuum the blade shell surface equably, minute bubbles in the layer of shop will successively see through shop layer, release cloth, mould release film in the environment of negative pressure, enter into and inhale the glue felt, flow through suction glue felt and enter into helix tube, enter vavuum pump at last, thereby bubble is eliminated.The present invention adopts vacuum bag pressure method to eliminate residual bubble in the layer of shop, has improved structural strength and service life.This is that traditional hand pasting forming is incomparable.

Fig. 2 is a process chart of the present invention.
Fig. 3 is prepreg manufacturing process figure.
The specific embodiment
The present invention is a kind of manufacture method of blades of large-scale wind driven generator, and it is a kind of auxiliary process of exploitation on the basis of hand paste technology: at first spray releasing agent on the forming surface of mould 6, be coated with gel coat; Carry out blade shell 7 then and lay, finish the shop layer and on blade shell 7, spread release cloth 3, mould release film 5 afterwards successively, inhale glue felt 1; Inhale vacuum screw pipe 8 at the circle that is provided with of inhaling blade shop, glue felt 1 outer layer all around; Again integral coating one deck is inhaled vacuum film 4, seal between four limits of suction vacuum film 4 and the mould 6 and join, can adopt sealing joint strip 5 sealings; Join inhaling the two ends of vacuum screw pipe 8 and the suction vacuum plant of peripheral hardware, vacuumize then, and hunt leak and mending-leakage; The final curing moulding.During construction, need be with blade shell 7 strict sealings.Exist if any the gas leakage point, bubble so herein can not be drained clean fully but also can make adjacent area produce defective.
Blade shell is laid in stacked shop several layers prepreg, described prepreg is that dried glass cloth 12 soaks a kind of material that obtains later through resin, its manufacturing process is at first dried glass cloth 12 to be walked around the roll coater 13 that is located in the steeping vat 14, again through about behind the plastic squeeze roller 10 on cloth-gathering roller 9.At dried glass cloth rewinder roll, roll coater 13, all be provided with some jockey pulleys between plastic squeeze roller 10, the cloth-gathering roller 9 per two up and down, between roll coater and dried glass cloth rewinder roll, also be provided with counting running roller 11.
