Abstract

The invention discloses a segmented fan blade, which comprises a fan blade back edge segment (1) and a fan blade body segment (2), wherein the fan blade back edge segment (1) comprises an upper casing (1-1), a lower casing (1-2) and an auxiliary pasting corner (1-3), the auxiliary pasting corner (1-3) for connecting the upper casing (1-1) with the lower casing (1-2), the upper casing (1-1) and the lower casing (1-2) consist of skins (1-4), core materials (1-5) and auxiliary beams (1-6), the fan blade body segment comprises a body segment upper casing (2-1), a body segment lower casing (2-2) and a rib plate (2-3), the body segment upper casing (2-1) and the body segment lower casing (2-2) are formed by a crossbeam (2-4) and a sandwich structure (2-4), and the rib plate (2-3) is formed by the sandwich structure (2-4). The segmented fan blade provided by the invention has the advantages that the structural design is reasonable, the mechanical intensity is high, the segmented fan blade design is adopted, the problem of transportation difficulty caused by too high blade loading height can be solved, and the transportation cost is low. In addition, a preparation and assembly method of the segmented flan blade provided by the invention has the advantages that the assembly is convenient, the work efficiency is high, and the reliability is high.

Description

[0001] technical field [0002] The invention relates to a fan blade, in particular to a segmented fan blade and a method for preparing and assembling the segmented fan blade, and belongs to the field of wind power generation. Background technique [0003] A wind turbine is a device that converts wind energy into electrical energy, and the blade is one of the core components of the wind turbine. In order to improve the utilization rate of wind energy, the capacity of a single wind turbine is continuously increasing, and the length and root diameter of the blades are also increasing. The ensuing blade transportation problem has not been properly resolved for a long time. Transportation safety issues and transportation cost issues are the key points. How to effectively reduce the cost of blade transportation while ensuring safe transportation has become a concern of those skilled in the art. The application of segmented blade technology can effectively solve the above probl...
