Problems solved by technology
[0003] Segmented blades have been developed at home and abroad for a long time, but due to the significant increase in the weight of the segmented blades at the segmented position, the weight and cost of the blade itself have increased significantly, resulting in poor economical efficiency of the segmented blades. Did not get actual wind field application

The invention discloses a segmented blade, a manufacturing process and a wind power generator set, comprising a first blade segment and a second blade segment connected to the first blade segment, the first blade segment includes a first connecting portion, The first connection part is formed in the main beam area of the first blade section and is located at the end of the first blade section, which includes a plurality of first elements joined adjacently, so that the first element has a shape such that two adjacent A socket is formed between the two first elements after joining; the second blade section includes a second connecting portion formed in the main beam area of the second blade section and located at the side of the second blade section an end portion comprising a plurality of adjacently joined first elements, and a plurality of second elements; the second elements are shaped to match the receptacle and are longer than the receptacle; each second element of the second blade section is inserted into the first Each receptacle of a blade segment connects the first blade segment and the second blade segment.
Description
technical field [0001] The invention relates to the field of manufacturing processes, in particular to a segmented blade, a manufacturing process and a wind turbine. Background technique [0002] As wind turbine blades grow in length, the cost and difficulty of transporting them increases significantly. In order to reduce the difficulty of transportation and greatly save transportation costs, segmented blades are the main development trend in the future. [0003] There has been a history of development of segmented blades at home and abroad, but due to the significant increase in the weight of segmented blades at the segmented position, the weight and cost of the blade itself increase greatly, resulting in poor economy of segmented blades. There is no actual wind farm application. Therefore, a lightweight and reliable connection method is the most demanded technology for segmented blades. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provi...
