Referring to figs. 1 to Fig. 3, this utility model embodiment provides a kind of wind power generating set subsection blade, it includes at least two along its length and/or tangential by connecting the blade sections that is sequentially connected with of assembly, connect assembly include being disposed therein in a blade sections connect chute 12 and be arranged in another blade sections with the connection sliding block 13 being connected chute 12 cooperation。The blade of wind power generating set is arranged to the stagewise being formed by connecting by least two blade sections, the requirement of the height to Factory Building and width can be reduced, reduce the construction cost of Factory Building to a certain extent, simultaneously, also large-scale blades problem of easy superelevation ultra-wide when transport is solved, decrease the requirement to means of transport and transport routes, reduce cost of transportation。Adopt the mode connecting chute 12 and connection sliding block 13 connection, be not only simple in structure, and ensure that between blade sections as dismountable type of attachment, it is simple to change and maintenance。
The length direction of blade refers to along the direction that root of blade extends to blade tip。The tangential of blade refers to along the direction that the leading edge of blade extends to trailing edge。
In the design and production process of blade, can by blade along its length or tangential segmentation, the length of each blade sections can be greatly reduced by segmentation along its length, can be greatly reduced by the width of each blade sections along its tangential segmentation。Certainly, it is possible to by blade along its length with segmentation while of tangential。After blade is carried out segmentation, each blade sections can individually be processed, and each blade sections is smaller, accelerates production efficiency, dramatically saves on the time taking mould in blade manufacturing process。Meanwhile, also each blade sections can be carried out modularized design, by different blade sections combinations is formed the wind power generating set subsection blade having aeroperformance in need。So, according to different wind power generating set, blade sections can be combined into required size, it is achieved that the function of one module multiple usages。
As depicted in figs. 1 and 2, it is by blade along tangential segmentation, and the quantity of the blade sections of each blade can be determined as required, is as the criterion not affecting blade overall construction intensity and aeroperformance。In this utility model embodiment, blade tangential is divided into three sections along it。For the ease of the connection between adjacent two blade sections, and ensure to improve the structural strength of the blade after connecting the joint efficiency between blade sections simultaneously, in the present embodiment, blade sections is fixedly installed the prefabricated component 1 made in advance。Specifically, in three blade sections, being positioned in the blade sections of both sides and be provided with this prefabricated component 1, the blade sections being positioned at both sides is attached respectively through prefabricated component 1 and centrally located blade sections。
As shown in Figure 6, connecting chute 12 one-body molded on prefabricated component 1, a part for this prefabricated component 1 is embedded in corresponding blade sections, connects chute 12 and is positioned at outside corresponding blade sections。This prefabricated component 1 can adopt metal or nonmetallic materials, if prefabricated component 1 adopts metal material, so require over lead-in wire and linked on main lightning conducter, to realize drawing the purpose of thunder, if prefabricated component 1 adopts nonmetallic materials, so it is used as nonmetallic materials adjacent blade segment is fixed, as long as ensureing that it disclosure satisfy that the strength demand connected between blade sections。In the present embodiment, connecting the one-body molded mode on prefabricated component 1 of chute 12 is stretch out formation bending structure in the part of blade sections at prefabricated component 1, and namely this bending structure forms connection chute 12。Certainly, in other embodiments, connecting chute 12 can also be one-body molded on prefabricated component 1 by modes such as cuttings。For preventing prefabricated component 1 from affecting the aeroperformance of blade, after this prefabricated component 1 is connected in blade sections, its shape with blade sections place is with type。
Preferably, reliably secure in order to make prefabricated component 1 connect in blade sections, prefabricated component 1 is embedded in the part in blade sections and is provided with at least one projection。The outer surface of this projection is arc。It is to say, the surface of the part being embedded in blade sections adopts ripple to process the contact area to increase itself and blade sections, thus increasing the prefabricated component 1 lifting surface area in blade interior, it is ensured that its bonding strength。
In the present embodiment, be positioned at the two ends up and down of the blade sections of both sides and be provided with this prefabricated component 1, and be in upper end prefabricated component 1 connect the opening up of chute 12, be in lower end prefabricated component 1 connect the opening down of chute 12。
Centrally located blade sections has 4 ends, and each end is equipped with connection sliding block 13。Connection sliding block 13 can be the bending segment of 4 ends of the blade sections being arranged in centre, and this bending segment is all to the internal bend of blade。So, after two blade sections assemble, connect chute 12 and connection sliding block 13 is fitted, it is ensured that round and smooth excessive of blade surface, thus without influence on the shape of blade surface, it is ensured that the aeroperformance of blade itself。
In an alternative embodiment, connect chute 12 and connection sliding block 13 can be configured as the connected mode mutually fastened or other can realize fastening, the connected mode positioned equally。When blade sections is spliced into blade by needs, have only to will be located in the connection sliding block 13 in the blade sections of centre and embed the connection chute 12 being arranged in the blade sections of both sides, then three blade sections are adjusted to aligned position and can realize for the blade sections splicing along its chordwise direction。Owing to adopting connection sliding block 13 between blade sections and connecting the connected mode of chute 12, thus can dismantle more easily, in actual use, if needing change blade or blade is keeped in repair, have only to corresponding blade sections is changed accordingly, which save the time changing blade or maintenance blade。
Certainly, in other embodiments, prefabricated component 1 also can be arranged in the two ends of the blade sections of centre, or by directly one-body molded in blade sections to connection chute 12 or connection sliding block 13, or by connecting, chute 12 and connection sliding block 13 are fixing with blade sections to be connected by other means。
Preferably, in order to ensure bonding strength, the length connecting chute 12 is identical with the length of the blade sections at its place, and the length of connection sliding block 13 is identical with the length of the blade sections at its place。
Further, in order to ensure the bonding strength between blade sections, the wind power generating set subsection blade that this utility model embodiment provides also includes locked component, and locked component is fixedly installed on connection assembly, and can lock adjacent two blade sections。Specifically, the two ends connecting chute 12 are provided with the first limiting through hole 2, connection sliding block 13 two ends are provided with the second limiting through hole 3, after adjacent two blade sections connect, first limiting through hole 2 and the second limiting through hole 3 one_to_one corresponding, locked component is located in corresponding first limiting through hole 2 and the second limiting through hole 3 correspondingly, and is locked in by connection sliding block 13 on connection chute 12, prevent both from separating, and then realize the locking to adjacent two blade sections。It is each passed through the first limiting through hole 2 with locked component and adjacent two blade sections are fixed together by the second limiting through hole 3, so that it may ensure can being stitched together securely of blade sections, the problems such as dislocation will not occur。In order to be further ensured that the bonding strength between blade sections, the first limiting through hole 2 can be uniformly arranged along the length direction connecting chute 12, the second limiting through hole 3 is uniformly arranged along the length direction of connection sliding block 13。But the spacing between adjacent two the first limiting through hole 2 or adjacent two the second limiting through hole 3 is unsuitable too small, in order to avoid the through hole owing to connecting on chute 12 or connection sliding block 13 is overstocked, cause the reduction connecting chute 12 or connection sliding block 13 self-strength, it is to avoid blade sections ruptures when splicing。In this utility model embodiment, locked component can be pin and lock ring assembly or screw bolt and nut assembly etc., and certainly, this locked component is alternatively other securing members being capable of interconnection function。
With reference to Fig. 4 and Fig. 5, owing to the length of blade is long, blade can be divided into multistage along its length。Also being connected by prefabricated component 1 between multistage blade sections, this prefabricated component 1 and previously mentioned prefabricated component 1 structure, effect are all identical。Specifically, in one end near blade root of blade sections, tangential along blade sections is disposed with connection sliding block 13 and connects chute 12, in one end away from blade root of blade sections, along tangential connection chute 12 and the connection sliding block 13 of being disposed with of blade sections, and connection chute 12 all protrudes from blade sections。
When blade sections is spliced into blade by needs, it is only necessary to after alignment about adjacent two sections of blade sections, then the connection sliding block 13 in adjacent two sections of blade sections and connection chute 12 are snapped together correspondingly, splicing can be realized。With locked component, adjacent two sections of blade sections can also be coupled together as required。When the length of blade is very long, it is only necessary to multiple blade sections be sequentially connected with, meanwhile, the surface of multiple blade sections is smooth excessiveness, can meet the different capabilities wind power generating set demand for blade completely。
In some alternate embodiment, when blade sections is spliced into blade by needs, in order to prevent blade from occurring when using, module is slided the problem causing module to separate with module certainly, can adopt limited block。Specifically, can arranging corresponding limited block on connection chute 12, when blade sections is connected by needs, connection sliding block 13 embed connection chute 12, when being mounted to correct position, limited block gets final product backstop, plays effect blade sections being positioned, fixing。
In concrete production process, according to actual situation, neatly blade along its length and/or tangential can be divided into some segmentations, produces the used time to reduce。In conjunction with blade sections modularized design, can when ensureing blade aerodynamic performance, the means of leading edge and/or rear edge part by changing blade realize the production and processing for different size blade, it is greatly saved blade design and manufacturing cost, meets the different capabilities wind-driven generator demand for blade。
Such as, at the wind field of low wind speed, it is necessary to adopt the blade profile that tangential width is relatively larger, blade is long, then by three blade sections along the tangential blade that is spliced into, and/or multiple blade sections can be spliced into along its length blade (as shown in figures 2 or 4)。Wind field at high wind speed, it is necessary to adopt the blade profile that tangential width is smaller, blade is comparatively short to reach the purpose of load shedding, then can be spliced into blade (as shown in Figure 3) by two blade sections along tangential。So not only reduce blade and produce the demand for Factory Building length and height, it is often more important that, multiple blade sections can simultaneously processing, decrease blade and account for the time of mould, reduce difficulty of processing, decrease the production cost expense of mould。
In order to ensure the sealing property of blade sections link position, this utility model embodiment is also provided with the sealing structure 4 filling and sealing this gap in gap between adjacent two blade sections especially。This sealing structure 4 can be the rubber being filled in this gap, it is possible to for spreading upon the finish paint of blade surface or being laid on the glass-fiber-fabric etc. of blade surface。The bonding strength further increasing between blade sections is so set, also ensure that the aeroperformance that blade is overall, also effectively prevent the erosion being subject to natural environment inside and outside blade sections parts simultaneously。
Certainly, in other embodiments, it is also possible to by adopting adhesive tape bonding or punching in blade sections and by pin or bolted mode, adjacent two blade sections be attached。Such as, by bolt, blade sections is coupled together on the fiberglass of blade along its length or tangential punching, but this mode needs to punch on fiberglass, affect its structural strength, and a part for bolt is exposed at outside blade easy corrosion and draws thunder, simultaneously need to bolt is carried out periodic maintenance。
