Embodiment 1

[0039] like Figure 1 to Figure 4 The shown modular wind turbine blade block connection structure includes a first member 10, a second member 20 and a connector 30; it should be noted here that the first member 10 and the second member 20 in the embodiment of the present invention are Refers to two adjacent modules in the modular connection structure of wind turbine blades, which can be two adjacent modules along the width direction of the wind turbine blade, or two adjacent modules along the length direction of the wind turbine blade;

[0040] In the embodiment of the present invention, the end faces of the first member 10 and the second member 20 facing each other have abutting surfaces, and the abutting surfaces are inclined as a whole, including a first abutting surface 11 provided on the first member 10 and a second abutting surface 11 provided on the second member 10 . The second abutting surface 21 on the component 20; it should be pointed out here that, in the embodime...

Embodiment 2

[0048] In the second embodiment of the present invention, the structural form of the connector 30 is improved, such as Figure 5 and Image 6 As shown in the figure, the reinforcing portion 22 extends and penetrates along the length direction of the butting surface, and the cross-section of the reinforcing portion 22 is a dovetail structure, and the side with the larger cross-sectional width of the reinforcing portion 22 is disposed in the direction away from the abutting surface. Through the arrangement of this structural form, a mortise-and-mortise structure similar to woodworking is realized, and the first member 10 and the second member 20 are closely connected together through the connector 30. It should be pointed out here that in the first member 10 An appropriate gap is set with the rest of the second member 20, so that the rest is also connected and fixed by structural glue;

[0049] In a preferred embodiment of the present invention, the reinforcing parts 22 on the ...

Abstract

The invention relates to the technical field of wind power blade manufacturing, in particular to a modular wind power blade block connecting structure and a splicing method, and the connecting structure comprises a first component, a second component and a connecting piece; the end faces, facing each other, of the first component and the second component are provided with butt joint faces, and the butt joint faces are integrally arranged in an inclined mode and comprise the first butt joint face arranged on the first component and the second butt joint face arranged on the second component. A gap is formed between the first butt joint surface and the second butt joint surface when the first butt joint surface and the second butt joint surface are butted; the connecting piece is of a structure formed by injecting a structural adhesive into a gap between the first butt joint surface and the second butt joint surface and curing the structural adhesive; wherein the first butt joint face and the second butt joint face are provided with reinforcing parts which are arranged in a sunken mode in the thickness direction of the first butt joint face and the second butt joint face, the reinforcing parts are communicated with the gap, and the connecting piece comprises a shape which is injected from the gap to the reinforcing parts to be cured and formed. The first component and the second component are connected in the curing process of the structural adhesive, the process is simple, and the splicing efficiency is high.

Description

technical field [0001] The invention relates to the technical field of wind power blade manufacturing, in particular to a block connection structure and a splicing method of a modular wind power blade. Background technique [0002] Wind turbine blades are the core components of wind turbines that convert natural wind energy into wind turbine electrical energy. With the development of large-scale wind turbine blades, carbon fiber and other composite materials have begun to be used to make wind turbine blades. In order to facilitate installation and transportation, wind turbine blades have also begun to be produced. Modular solution, but the connection reliability between modules has become a key technical link; [0003] In the related art, in order to improve the structural strength of the splicing surface, a large slope structure is mostly used in the splicing surface, and the skin is used as a reinforcing layer to improve the connection strength. However, the above-mentione...
