Problems solved by technology

Segmented wind rotor blades need to be assembled into complete blades during use. In the prior art, during the connection process of segmented wind rotor blades, slots are processed at the joints of the blades, and fillers are added to the slots. Bonding, connecting with separate fasteners, and superimposing reinforcement structures on the inner and outer surfaces to connect the segmented blades together, but the existing connection technology is aimed at the load conditions and on-site installation of the wind turbine blades in actual work. At the same time, when fasteners and superimposed structures are applied in actual engineering, problems such as insufficient strength of blade joints and large aerodynamic losses will occur, and there are disadvantages of complex actual assembly operations, high costs, and high risks. , however, the structure of the segmented wind rotor blade itself directly affects its assembly method, so it is necessary to improve the structure of the existing segmented wind rotor blade and its assembly method

Embodiment Construction

[0029] In order to facilitate the understanding of the structure and the achieved effects of the present invention, the preferred embodiments are listed in detail as follows with reference to the accompanying drawings.

[0030] The wind rotor blades in the present invention are multi-section wind rotor blades, such as figure 1 As shown, the wind rotor blade includes a blade root section 1 and at least one radial blade 2, and main beams 3 are embedded in the blade root section 1 and each radial blade 2, and through the sequential connection between the main beams 3, The blade root section 1 is connected end to end with each radial blade 2 to form a complete wind rotor blade.

[0031] Such as image 3 As shown, the blade root section 1 in the wind turbine blade of the present invention is close to the hub side, and the blade root section 1 and the internal main beam 3 are consolidated together during manufacture, and the end surface of the blade root section 1 on the side away ...

Abstract

The invention discloses sectional type wind wheel vanes of a wind power generator set and an assembly method thereof. The sectional type wind wheel vanes comprise a vane root segment and at least one radial vane, wherein the vane root segment is close to one side of a wheel hub, main beams are embedded in the vane root segment and all radial vanes, and the vane root segment and each radial vane are connected end to end by sequentially joining the main beams. By the sectional type wind wheel vanes, the effects of large connection strength and small pneumatic loss can be realized.

Description

technical field [0001] The invention relates to a wind rotor blade and an assembly method thereof, in particular to a segmented wind rotor blade and an assembly method thereof used in an extra-large wind power generating set. Background technique [0002] At present, with the enhancement of people's awareness of environmental protection, the application of wind energy is becoming more and more extensive, and the wind power generating set has realized the conversion between wind energy and electric energy. The wind rotor blade is the core component of the wind turbine, and the swept area of ​​the wind rotor blade directly determines the output power of the wind turbine. As the single unit capacity of wind power generators continues to increase, the length of the wind rotor blades is also increasing. However, such long wind rotor blades are very inconvenient in the process of production, transportation and hoisting. Therefore, the segmental manufacturing method can be used to...
