Fan blade and wind driven generator

The invention provides a fan blade and a wind driven generator. The fan blade comprises a blade tip section, a blade root section and a connecting piece. After the first connecting end of the blade tip section is in butt joint with the second connecting end of the blade root section, the connecting piece made of thermoplastic materials is adopted to be bonded and fixed together with the first connecting end and the second connecting end in a heating and pressurizing mode. The invention provides the wind driven generator. Through the arrangement, the connecting position of the blade tip section and the blade root section is light in weight and more reliable in connection, and therefore the influence on the load of the whole machine is small, the structure is simple, and factory production and wind field on-site operation are facilitated. 本申请提供一种风机叶片和风力发电机。风机叶片包括叶尖段、叶根段及连接件。在叶尖段的第一连接端与叶根段的第二连接端对接后，采用由热塑性材料制成的连接件并通过加热、加压的方式与第一连接端和第二连接端粘接固定。本申请提供一种风力发电机。如此设置，使叶尖段与叶根段的连接处的质量轻，连接更加可靠，从而对整机载荷影响较小，且结构简单，便于工厂生产以及风场现场操
