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.
