Wind turbine blade of wind turbine generator system

Abstract

The invention relates to the technical field of wind power generation, and provides a wind turbine blade of a wind turbine generator system. The wind turbine blade is characterized in that a cavity isformed in a blade body, a supporting structure is arranged in the cavity; the blade body is provided with an elastic trailing edge, and the elastic trailing edge extends along the first side wall andthe second side wall of the blade body and is closed; and the cross section of the elastic trailing edge is a conical cross section, the elastic trailing edge comprises a first elastic wall and a second elastic wall, and the elastic trailing edge can be locally elastically deformed and integrally elastically deformed. The wind turbine blade has the beneficial effects that the elastic trailing edge is arranged in the blade body, and the polymer-based material with elastic elongation is introduced, so that the single material mode of the blade structure of the traditional fiber reinforced plastic is changed, the elastic trailing edge of the blade body can reduce the load input through elastic deformation, and the safety of the whole wind turbine generator system and all parts thereof is guaranteed from the source.

Description

technical field [0001] The invention relates to the technical field of glass forming, and more specifically, relates to a wind turbine blade of a wind power generating set. Background technique [0002] Through its specific geometric shape, the rotor blades of the wind turbine can realize the purpose of converting the captured wind energy into rotating mechanical energy and driving the generator set to generate electricity. [0003] Wind is a natural force that is not very stable, and its changes are irregular, especially in areas with relatively complex terrain, sometimes there will be sudden and severe disastrous gusts (typhoons are only one type of such disastrous gusts), The blades are subjected to a large load instantaneously, resulting in excessive bending deformation, and the deformation reaches a certain level, which is very easy to cause safety accidents. Even if the blades can bear it, the main engine or even the tower can not bear it, resulting in accidents. The ...

AI Technical Summary

Problems solved by technology

It takes a time process to start the mechanical device, and it takes a time process to remove the protection and start the mechanical device. It must be considered that the application purpose of the wind turbine is to generate electricity. There must be a systematic balance between the degree of safety and the cost, and the cost of changing this balance is very high. High, the economy of the entire fan system will be greatly reduced, and to a considerable extent, the life of the related pitch protection mechanism is proportional to the number of operations
