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.
