Abstract

The invention discloses a shock-resistance segmented wind power blade and an assembly method thereof. The blade comprises at least two blade sections; a connecting device is connected between the blade sections, and includes two connecting frames; the connecting end surfaces of the connecting frames and the blade sections are matched in shape; first mounting holes are formed in the connecting frames; first bolts for tightly connecting with the blade sections are arranged in the first mounting holes; multiple hinge pieces for buffering are connected between two connecting frames; the rotating direction of all the hinge pieces is consistent with the stress direction of the blade sections; and limiting pieces for limiting swing of the blade sections are connected between the two connecting frames. The method comprises the steps of: (S1) manufacturing and transportation; (S2) installation; and (S3) building of pneumatic shape of the blade. The shock-resistance segmented wind power blade has the advantages of convenience for assembly and disassembly, high connecting strength and high reliability.

Description

technical field [0001] The invention mainly relates to the technical field of wind power generation equipment, in particular to an impact-resistant segmented wind power blade and an assembly method thereof. Background technique [0002] At present, wind power blades are developing in the direction of large size. For example, the blade length of the V164-7MW model of Vitas in Denmark is as long as 80m. The higher the rigidity requirement, the more difficult it is to manufacture. Therefore, manufacturing the blades in sections and transporting them in sections can better solve the above problems. [0003] At present, in the mechanical connection scheme of the segmented blades, the segmented blades are usually directly and rigidly connected by bolts or the like. The upper and lower airfoil arc plates in the middle of the blade are connected by bolts. This segmented blade with rigid connection has poor impact resistance under extreme working conditions, and external factors ar...
