Overlap joint 300mm, after web 9 fixes, windward side 12 is bonding with lee face 14 matched moulds, and blade tip section 1 is solid
After changing the demoulding, do extra reinforcement solutions again at the front and rear edges areas adjacent having insert;In order to prevent rainwater
Or foreign material enter in blade cavity, at distance end face 100mm, make end face baffle plate 11, windward side 12
Baffle plate need to be passed with the lightning protection wire 8 at lee face 14, expose insert binding face 100mm;Then according still further to
Same manufacturing process completes the making of blade root section 2.
3) examination combination is carried out at the scene of manufacturing, by end flanges 501 and the blade root of the posture steel construction 5 that spreads out
The binding face alignment of first insert the 6, second insert 7 of section 2, if binding face occurs the most concordant defect,
Then need to fill in thin metallic gasket and ensure concordant;In order to save engineering site built-up time, can be by the posture steel knot that spreads out
Structure 5 is connected with blade root section 2 and mails to engineering site in the lump;Posture of spreading out steel construction 5 and blade root section 2 pass through double end
Bolt 16 connects, and is locked with self-locking nut, simultaneously by the lightning protection wire 8 of blade root section 2 by screw 17
It is fixedly connected on the end flanges 501 of the posture steel construction 5 that spreads out.
4), during engineering site docking, first blade root section 2 is docked after being completed with the hub end of wind-driven generator,
Carry out blade tip section 1 again to assemble with blade root section 2, during assembling, by first insert the 6, second insert of blade tip section 1
The binding face of 7 aligns, if binding face occurs not with end flanges 502 binding face of the posture steel construction 5 that spreads out
Concordant defect, need to fill in thin metallic gasket the most equally and ensure concordant, the most again by stud 16 and self-locking
Nut check fixes blade tip section 1 and the posture steel construction 5 that spreads out, simultaneously by the lightning protection wire 8 of blade tip section 1
It is fixedly connected on the end flanges 502 of the posture steel construction 5 that spreads out by screw 17.
5) check after the combination of blade tip section 1, posture of spreading out steel construction 5, blade root section 2 three part whether with design chi
Very little data consistent, no problem after, first with 3 layers wide for 500mm three axle cloth handss stick with paste, parcel spread out posture steel knot
Structure 5, blade root section 2 and the bonding plane of blade tip section 1, after cured, then before blade root section 2 and blade tip section 1,
100mm width rapid structural glue is executed, by the first aerodynamic configuration compoboard 3 and the second gas at trailing edge and bonding plane
Dynamic profile integration plate 4 is adjacent to bonding plane.
6) pressed home frock 18 is used to clamp at the seam crossing of blade tip section 1 and the seam crossing of blade root section 2,
Docking profile is made to can be good at coincideing, it is ensured that the aerodynamic configuration profile of whole blade is consistent with Design Theory,
Pressed home frock 18 is removed again after structure glue is fully cured.As shown in Figure 10-Figure 12, described extruding is multiple
Position frock 18 includes first pressure strip the 1802, second pressure strip 1803 of band steelframe 1801, and described first
The seal face of pressure strip the 1802, second pressure strip 1803 and respective first aerodynamic configuration compoboard 3,
The shape size of the second aerodynamic configuration compoboard 4 matches, the steelframe and second on this first pressure strip 1802
Steelframe on pressure strip 1803 is tighted a bolt 1806 connections by two ends, so by the first pressure strip 1802,
Second pressure strip 1803 combination is formed as the structure that shape size position to be clamped with blade matches.Wherein,
Pressed home frock making and operation instruction: the seal face of first pressure strip the 1802, second pressure strip 1803 exists
On the formpiston in blade section region, the system of turning over forms, and sticks with paste junction steel plate 1804 at its back side hands and welds with steelframe 1801
Connect, then two ends column end face burn-on tension flanged plate 1805;During use, two ends elder generation pre-screwing bolt 1806,
After seal face is fitted with aerodynamic configuration compoboard profile, bolt 1806 is twisted by front and rear edges two ends simultaneously
Tightly, it is ensured that uniform force, after docking profile is coincide, it is ensured that pretightning force.
7) polish off the structure glue more than needed of seam crossing, stick with paste 6 slice widths at seam crossing and front and rear edges abutting edge hands
The three axle cloth of 400mm carry out reinforcement, and every fault opens 50mm, then hands sticks with paste surface felt, opponent's paste layer after solidification
After carrying out transition polishing polishing with prototype face, brush the paint consistent with prophyll sheet tone, to here
Whole sectionally assembled blade of wind-driven generator just completes, with wheel hub one after a whole set of blade assembling completes
Play lifting on-hook to run.
The examples of implementation of the above are only the preferred embodiment of this utility model, not limit this practicality with this
Novel practical range, therefore the change that all shapes according to this utility model, principle are made, all should contain at this
In the protection domain of utility model.
