Embodiment Construction

[0029] In order to better understand the purpose, structure and function of the present invention, a wind turbine blade web lay-up structure and lay-up method of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0030] Such as Figure 1 to Figure 4 As shown, it is shown as a wind power blade web lay-up structure and lay-up method of the present invention, especially for large-scale wind power blade web laying, in the blade web mold 1 (leading edge web mold and trailing edge web mold Die) lay glass fiber cloth 2, core material 3 and various auxiliary materials. In the present invention, multiple layers of sewn glass fiber cloth 2 and core material 3 are laid in the web mold 1, and two-way simultaneous laying is carried out in the axial direction, so as to improve the laying speed and quality.

[0031] further, such as figure 1 As shown, the laminated structure of the blade web (leading edge web and trailing edge w...

Abstract

The invention discloses a wind power blade web layering structure and a layering method thereof. The wind power blade web plate layering structure comprises a blade root layering area, a transition layering area and a blade tip layering area, wherein the blade root layering area, the transition layering area and the blade tip layering area are sequentially divided by a leading edge web and a trailing edge web from a blade root to a blade tip; multi-layer glass fiber cloths respectively laid on the lower left layer of the blade root and the lower right layer of the blade root overlap with eachother chordwise; multi-layer glass fiber cloths respectively laid on the upper left layer of the blade root and the upper right layer of the blade root overlap with each other chordwise; multi-layer glass fiber cloths on the lower left layer of the blade root and glass fiber cloths on the lower layer of the blade tip overlap with each other axially; and multi-layer glass fiber cloths on the upperright layer of the blade root and the glass fiber cloths on the upper layer of the blade tip axially overlap with each other. According to the wind power blade web layering structure and the layeringmethod thereof, the web glass fiber cloths are divided into a plurality of pieces by sewing in advance, and the multi-layer glass fiber cloths are laid at one time; zoning of the web layering is carried out, and synchronous and bidirectional operation is carried out without mutual interference; and the operation is simple and convenient, the web laying time is shortened, and the laying speed and quality are improved.

Description

technical field [0001] The invention relates to the field of wind power blades, in particular to a wind power blade web layer laying structure and a layering method. Background technique [0002] With the continuous upgrading of technology, wind power blades are rapidly developing in the direction of large-scale, and the blades of more than 90 meters have entered the stage of mass production. Correspondingly, the webs of wind power blades are getting longer and longer, and the laying time is also increasing. The web is generally designed as several layers of glass fiber cloth + core material + several layers of glass fiber cloth. Due to the width limit, each layer of glass fiber cloth is made of several pieces of glass fiber cloth, especially those with large pre-bending There are more blades and glass fiber cloth. Moreover, during the production process of the web, workers lay layers from the root of the web to the tip, and can only lay one layer before laying the next la...
