Split-assembling-type blade of wind driven generator

The invention provides a split-assembling-type blade of a wind driven generator. The blade comprises a shell and a stiffening beam; the stiffening beam is arranged at the interior of the shell along the length direction of the blade and supports the inner surface and outer surface of the blade; the shell is spliced by a plurality of sections of split shells along the length direction of the blade; the stiffening beam penetrates through all the split-type shells; and a stiffening beam limit device is correspondingly arranged at the interior of each split-type shell. The split-assembling-type blade provided by the invention has the advantages of low manufacturing difficulty and simple process; the quality can be easily ensured, the technology is simple and can be easily realize, the problems of complex production process and difficult transportation of the traditional integrated-type blade are solved, and the convenience of transportation is improved greatly, which is good for improving the efficiency, saving energy and reducing emission; and the blade is suitable for popularizing and using in a large scale.
