in the embodiment of the present invention, the end surfaces of the first member 10 and the second member 20 facing each other have abutting surfaces, and the abutting surfaces are arranged obliquely as a whole and include a first abutting surface 11 provided on the first member 10 and a second abutting surface 21 provided on the second member 20; it should be noted here that in the embodiment of the present invention, the purpose of arranging the butting faces obliquely as a whole is to increase the area of the butting faces, that is, to increase the effective contact area of the butting faces, thereby increasing the connection reliability; the first abutting surface 11 and the second abutting surface 21 are in principle of complementary shapes, i.e. the first abutting surface 11 and the second abutting surface 21 are two surfaces cut along the thickness direction of the component;
when the first butt joint surface 11 and the second butt joint surface 21 are butted, a gap is formed between the first butt joint surface 11 and the second butt joint surface 21, wherein the gap is used for forming the connecting piece 30, and as shown in fig. 1, when the positions of the first member 10 and the second member 20 are fixed, a structure formed by injecting structural glue into the gap between the first butt joint surface 11 and the second butt joint surface 21 is cured;
furthermore, in the embodiment of the present invention, in order to further enhance the connection strength between the connection member 30 and the first and second members 10 and 20, as shown in fig. 2, the first and second abutting surfaces 11 and 21 have the reinforcement portion 22 concavely provided thereon in the thickness direction thereof, the reinforcement portion 22 is communicated with the gap, and the connection member 30 includes a shape injected from the gap to the reinforcement portion 22 and cured. It should be noted that, although the present invention is modified by forming a gap between the first member 10 and the second member 20 to connect the two members, and injecting glue to connect the two members, the present invention is still within the scope of the present invention.
In the above embodiment, by providing the abutting surfaces on the first member 10 and the second member 20 and providing the gap and the reinforcing portion 22 between the first abutting surface 11 and the second abutting surface 21, the curing molding of the connecting member 30 between the first member 10 and the second member 20 is realized by glue injection, so that the first member 10 and the second member 20 are connected in the process of curing the structural glue, and compared with the prior art, the process is simple and the splicing efficiency is high.
On the basis of the above embodiment, with reference to fig. 1 and fig. 2, the first abutting surface 11 and the second abutting surface 21 are disposed in parallel, and both include a first inclined section 21a, a horizontal section 21b connected to the first inclined section 21a, and a second inclined surface connected to the horizontal section 21b, and the reinforcing portion 22 is disposed on the horizontal section 21 b. The two splicing surfaces are parallel, namely the intervals between the two splicing surfaces at the same position are the same, through the arrangement, the connection strength of the structural adhesive at each position can be ensured to be consistent, the connection reliability in each direction after connection can be improved in a mode that the first butt joint surface 11 and the second butt joint surface 21 are arranged into the first inclined section 21a, the horizontal section 21b and the second inclined section 21c, the connection reliability can be improved, and the construction difficulty can be reduced by arranging the reinforcing part 22 on the horizontal section 21b, so that after the reinforcing part 22 is arranged on the horizontal section 21b, the connection strength of the connection in the horizontal direction and the vertical direction can be improved through the connection of the horizontal section 21b and the reinforcing part 22, and the connection strength in the inclined direction can be improved through the arrangement of the two inclined sections; it should be noted that, of course, the inclination angle between the first inclined section 21a and the second inclined section 21c is not limited in the embodiments of the present invention, and may be an inclined manner as shown in fig. 1, an inclined manner as shown in fig. 6, or other manners capable of realizing splicing;
in the embodiment of the present invention, as shown in fig. 1 and 2, the reinforcing portions 22 are holes penetrating in the thickness direction of the first member 10 and the second member 20, and are uniformly provided in plurality in the length direction of the abutting surface. Through the arrangement of through hole positions, a form similar to bolt connection is formed; in the embodiment of the present invention, with reference to fig. 2, an end of the reinforcing portion 22 away from the horizontal section 21b is flared. The formation of a rivet cap-like structure is achieved by the flared arrangement, so that the fixing takes place in the thickness direction of the first component 10 and the second component 20, which further increases the reliability of the connection in a manner defined by the adhesive-bonded structure.
Further, as shown in fig. 3 and 4, the first inclined section 21a and the second inclined section 21c are rounded at both end surfaces of the first member 10 and the second member 20. Through the arrangement of the chamfer, the connecting piece 30 forms a barb form with two ends covering the first member 10 and the second member 20 when being molded, so that the structure is limited at the starting point of the connection, and the fracture and the separation of the connection are further prevented.
Example two
In the second embodiment of the present invention, the structural form of the connecting member 30 is modified, as shown in fig. 5 and 6, the reinforcing portion 22 is disposed to extend through along the length direction of the abutting surface, the cross section of the reinforcing portion 22 has a dovetail structure, and the side of the reinforcing portion 22 with the larger cross section width is disposed in the direction away from the abutting surface. Through the arrangement of the structural form, a mortise and tenon structure similar to that in woodworking is realized, the first member 10 and the second member 20 are tightly connected together through the connecting piece 30, and it is noted that a proper gap is arranged at the rest part of the first member 10 and the second member 20, so that the rest part is also connected and fixed through structural glue;
in the preferred embodiment of the present invention, the reinforcement portions 22 on the first abutting surface 11 and the second abutting surface 21 are disposed in communication, and the gap between the first abutting surface 11 and the second abutting surface 21 is replaced by the reinforcement portion 22 in communication. As shown in fig. 6, by means of communicating the reinforced portions 22 on the first abutting surface 11 and the second abutting surface 21, the connecting member 30 fixes the first member 10 and the second member 20 together, and by such a structure and the effect of the structural adhesive, the first member 10 and the second member 20 are uniformly fixed in the vertical, left and right directions, so that a gap can be reduced or even not required to be reserved at other places of the first abutting surface 11 and the second abutting surface 21, only the first member 10 and the second member 20 need to be spliced together, and the convenience of molding is improved;
as shown in fig. 7 and 8, in the embodiment of the present invention, when there is no gap between the first abutting surface 11 and the second abutting surface 21, in order to further improve the connecting strength of the two, as shown in fig. 8, a plurality of dovetail grooves 23 are further uniformly distributed along the length direction of the splicing surface in the horizontal section 21b, and the dovetail grooves 23 are communicated with the reinforcing portion 22. In this way, by the transverse arrangement of the dovetail grooves 23, after the first member 10 and the second member 20 are butted, the first member 10 and the second member 20 are also reinforced in the tenon-and-mortise structure in the length direction of the butted surface by means of glue injection, and by communicating with the reinforcing part 22, the first member 10 and the second member 20 are reliably connected by filling structural glue through the two dovetail grooves 23 in the thickness direction, and in the embodiment of the present invention, with continued reference to fig. 8, the dovetail grooves 23 extend from the end surface where the first inclined section 21a is located to the end surface where the second inclined section 21c is located. Through the arrangement of the mode, the volume of the connecting piece 30 is close to the whole volume of the butt joint face, and then the structure is integrated, so that the connecting strength is greatly improved.
The method for splicing the modular wind power blade block connecting structure in the embodiment of the invention is described as follows, and specifically comprises the following steps:
s10: butting the butting surfaces of the first member 10 and the second member 20 according to a set gap, and fixing the positions of the first member 10 and the second member 20; it should be noted here that the set gap may be a gap as shown in fig. 3, or may be in the form of a gap as shown in fig. 6;
s20: coating a vacuum film on the butt joint surface of the first member 10 and the second member 20; the butt joint surface is substantially at the position of the butt joint surface, and a layer of vacuum film is coated on the outer sides of the first member 10 and the second member 20, so that the cavity where the vacuum film is located coats the whole butt joint surface, and further preparation is made for vacuum glue injection below;
s30: injecting structural adhesive towards the butt joint surface of the same side of the first component 10 and the second component 20, and vacuumizing from the other side; by the vacuum-pumping glue injection mode, no dead angle of glue injection can be ensured, and all gaps in the butt joint surface are filled with the structural glue, so that the connection strength and reliability are improved;
s40: and continuing injecting glue, stopping injecting glue when structural glue appears at the vacuumized position, and waiting for solidification and forming of the structural glue to form the connecting piece 30 for fixing the first component 10 and the second component 20 together. Because the vacuum tube is located at the other side of the glue injection tube, when structural glue appears in the vacuum tube, the gap between the first member 10 and the second member 20 is filled, glue injection is stopped at the moment, and structural glue is waited for curing and forming.
