Embodiment
As Fig. 2～shown in Figure 6, the present invention is the packaging blade of a kind of wind-driven generator split, and this blade comprises shell and buttress brace.The blade enclosure inner hollow is partitioned into some split type housings 3 along the length direction of blade, generally is divided into 2～3 according to the size specification of blade.In the present embodiment, blade enclosure is divided into 3 split type housings 3, is respectively tip segment, intermediate portion and the leaf root part of shell.The split type housing 3 of plurality of sections splices mutually, constitutes a complete blade enclosure with blade internal surface a, blade outer surface b.
Buttress brace is two, and along the length direction symmetry of blade, be set in parallel in enclosure, the length of buttress brace equals the length of blade, the height setting in highly corresponding blade enclosure cross section, support blade internal surface a and blade outer surface b thus.Run through all split type housings 3 by buttress brace, split type housing 3 is coupled together, simultaneously, split type housing 3 inner correspondences are provided with the limit stoper of buttress brace, promptly locate the structure of buttress brace.
Shown in Fig. 2,3, split type housing 3 ends that the end of the split type housing 3 of tip segment is provided with tip baffle 4, leaf root part are provided with blade root dividing plate 8, the corresponding limit stoper that is provided with buttress brace on tip baffle 4 and the blade root dividing plate 8, the axially locating that is used for buttress brace, i.e. fixed-site on the length of blade direction.Wherein, blade root dividing plate 8 is installed, the fixing the other end of buttress brace at last after split type housing 3 connects fully again.
As shown in Figure 4, because the blade profile shape of present embodiment is because aerodynamic design is streamlined, its highly curved variation, at crossbeam mounting point 6 and 7 places, girder mounting point, two corresponding blade internal surfaces of buttress brace are installed and are provided with identical orientation angle, this orientation angle is: 70 ° ~ 100 °, present embodiment is got 60 ° ~ 90 °.Two reinforcement depths of beam, cross sections have nothing in common with each other, and therefore are divided into crossbeam 1 and girder 2.Crossbeam 1 is set to cored beam, further alleviates the overall weight of blade, and girder 2 is designed to solid beam, further the bulk strength of reinforced blade.Corresponding crossbeam mounting point 6, split type housing 3 inwalls are provided with crossbeam location shoulder 9; Corresponding girder mounting point 7, split type housing 3 inwalls are provided with girder location shoulder 10.Crossbeam location shoulder 9 and girder location shoulder 10 all are 4, and crossbeam location shoulder 9 and girder location shoulder 10 are symmetricly set on respectively on four contact position of crossbeam 1 and girder 2 and split type housing 3 inwalls.
Shown in Fig. 5,6, the joint 5 of two adjacent split type housings 3 adopts corresponding spacing seam butt joint, and corresponding spacing stop portion adopts adhesive securement.Simultaneously, the surface flatness of blade when guaranteeing that blade facings the wind, the blade outer surface b of joint 5 is provided with the groove 12 that applies binder, and this groove 12 promptly in split type housing 3 course of working, leaves other machining allowance of mm level and gets final product.
In the present embodiment, Bond adopts space and the blade surface laying fibre cloth 11 of joint 5 and the mode that bonds by resin solidification between spacing stop portion.And the fibre cloth 11 of spacing stop portion is continuous with the fibre cloth of blade surface, and when housing was made, this part fiber is perfusion resin not.During butt joint, will lay on adjacent two split type housings 3 earlier fibre cloth intersect, adopt the method for perfusion resin to connect again and fix, can guarantee the good communication of load between adjacent two split type housings 3 and the intensity of joint like this.Simultaneously, the surface flatness of blade when guaranteeing that blade facings the wind, the blade outer surface b of joint 5 is provided with and is used to spread the groove 12 that covers fibre cloth and resin, to guarantee that blade profile adheres to specification and smooth surface.Adjacent split type housing 3 be connected and fixed the employing following steps:
1, coarse processing is carried out on spacing seam joint 5 surfaces of two adjacent split type housing 3 correspondences.
2, two adjacent split type housings 3 of butt joint make two spacing seams combinations of correspondence tight, cooperate firmly, and the fibre cloth 11 between adjacent two split type housings 3 is intersected mutually.
3, after the butt joint, lay fibre cloth near blade internal surface a joint 5 and the groove 12 of blade outer surface b, note keeping the height of fibre cloth highly consistent with blade outer surface b.
4, after laying is finished, the liquid resin that will be mixed with a certain proportion of curing agent (as amine curing agent, acid anhydride type curing agent etc.) pours in the fibre cloth that enters on blade internal surface a and the blade outer surface b, simultaneously, this liquid resin injects in the fibre cloth on spacing seam joint 5 surfaces by the slit between the split type housing 3.Wherein perfusion resin adopts the resin identical with blade body, as unsaturated polyester resin, epoxy resin etc.
5, after perfusion is finished, at normal temperatures or the method for heating resin fibre cloth is cured, make adjacent two split type housings 3 bonding closely, intensity reaches requirement.
At last, blade outer surface b is carried out fine finishing, its surface flatness is met the demands.
