Abstract: A spanwise segment connection structure for wind turbine blades includes a first segment and a second segment provided along the length direction of the wind turbine blade. At least one splicing surface is provided between the first and second segments; and a structural adhesive layer provided at the splicing surface for splicing and fixing the first and second segments; wherein the bonding length of the structural adhesive layer conforms to the inclination angle of the slope structure, and a biaxial fabric reinforcement layer is provided on the outer side of a skin interface of the splicing surface. The weight of the blade is reduced and the production cost is reduced through the bonding and fixing of the first and second segments. The splicing surface in form of the slope structure increases the bonding area and reduces the stress concentration on the splicing surface of the first and second segments.

Abstract: A modular wind turbine blade includes a blade root, an intermediate portion and a blade tip. The intermediate portion includes a plurality of modular blades, two adjacent modular blades being provided at edge thereof with a first connecting portion and a second connecting portion that cooperate with each other, and wherein the plurality of modular blades includes a trailing edge shell, a leading edge shell and a main beam, respectively, the first connecting portion at the edge of the trailing edge shell and the leading edge shell being fixedly connected to the second connecting portion at the edge of the main beam. The wind turbine blade according to the present invention adopts segmented modular structural design, which effectively reduces the mold occupancy time of the blade, shortening the production cycle and improving the molding efficiency.
