Abstract

The invention discloses a sectional type fan blade and an assembling method thereof. The sectional type fan blade comprises a first blade section, a second blade section and a connecting assembly, wherein after the first blade section is connected with the second blade section through the connecting assembly, the first blade section, the connecting assembly and the second blade section form a whole; the connecting assembly comprises a socket piece, an insertion piece and a fixing assembly, a socket groove is formed in the socket piece, the insertion piece is matched with the socket groove, and the fixing assembly is used for fixing the relative position between the socket piece and the insertion piece; and one of the socket piece and the insertion piece is formed at the end, close to the second blade section, of the first blade section, and the other one of the socket piece and the insertion piece is formed at the end, close to the first blade section, of the second blade section. According to the sectional type fan blade, connection of the sectioned blades can be more reliable, the additional mass of the sectioned positions is light, and factory production and wind field on-site operation are facilitated.

Description

technical field [0001] The invention relates to the technical field of fan blades, in particular to a segmented fan blade and an assembly method thereof. Background technique [0002] As wind turbine blades become longer and longer, the cost and difficulty of their transportation increase significantly. In order to reduce the difficulty of transportation and greatly save transportation costs, segmented fan blades are the main development trend in the future. [0003] Segmented fan blades have been developed at home and abroad for a period of time, but due to the significant increase in the weight of the segmented fan blades at the segmented position, the weight and cost of the blade itself have increased significantly, resulting in the economical efficiency of the segmented fan blades. It is poor, and has not been applied in actual wind farms in China. Therefore, a lightweight and reliable connection method is the most required technology for segmented fan blades. Conten...
