<p>A wind turbine blade structure, a processing and forming method and applications thereof are provided. The blade consists of a root segment, a main beam and a covering that wraps the root segment and the external side of the main beam; the blade is fixed with a wind wheel by a connecting piece that is arranged at the root segment, thus forming a spatial cantilever beam structure; at the main beam area and the root segment, one or more solid or hollow wedge-shaped columns (1,1') are arranged between a top paving layer (4) and a bottom paving layer (2); the wedge-shaped column (1,1') at the internal-most side of the root end is solid and is internally provided with the connecting piece, wherein the fiber cloth is arranged at least among the adjacent wedge-shaped columns at the internal-most side of the root segment and continuously intersects and enwinds the wedge-shaped columns in a horizontal S-shaped, thus forming an interlayer; and the top paving layer, the bottom paving layer and the fiber cloth interlayer are dipped with glue and solidified to form a framework with a honeycomb-shaped section. The structure and the method have the advantages of: leading the once pouring of resin and once solidifying and forming for the large blade and the realizing of the pre-embedding of the connecting piece of the root part to be possible, dispersing the synergistic effect and solidifying shrinkage quantity of solidified heating of the bottom paving layer and the top paving layer by the wedge-shaped columns, and leading the unsaturated resin used as a substrate material to be possible.</p> |
