Problems solved by technology

[0005] The lightning protection metal blade tip prepared by the above prior art, when the adhesive is not fully cured, the blade tip is easy to warp, and the blade tip and the SS surface or PS surface on the blade are prone to misalignment
In addition, when using adhesives for bonding, it is inevitable that there will be bonding bubbles and cavities, which will cause cracks in the lightning protection metal tip, resulting in a decline in the quality of the lightning protection metal tip, which in turn will affect the performance of the lightning protection metal tip

Abstract

The invention provides a blade tip of a wind generating set and a preparation method thereof. The preparation method comprises the following steps that an insulating layer is wrapped around the outerperipheral surface of a designated part of a metal blade tip body; the designated part of the first surface of the metal blade tip body is placed right opposite to a non-metal first surface shell of ablade; and vacuum perfusion is carried out on the metal blade tip body and the first surface shell which are placed opposite to each other so as obtain the metal blade tip body and the first surfaceshell which are combined into a whole. According to the blade tip of the wind generating set and the preparation method thereof, the metal blade tip body and the first surface shell (such as a leewardsurface shell) of the blade are fixedly combined into a whole through a vacuum perfusion method, so that the problem that a metal blade tip body and a blade are staggered can be solved, the quality of the blade tip is improved, and then the performance of the lightning-protection metal blade tip is ensured.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular, the invention relates to a blade tip in a wind power generating set and a preparation method thereof. Background technique [0002] Wind energy, as a renewable clean energy, has been paid more and more attention by countries all over the world. Among them, wind power generation is one of the most widely used wind energy at present, which is not only environmentally friendly but also can generate a large amount of electric energy. [0003] Wind turbine is the core component of wind power generation, and its function is to convert wind energy into mechanical work. A wind generator includes a wind rotor, and a common wind rotor includes three blades, which rotate around an axis when the wind blows, thereby converting the kinetic energy of the wind into mechanical energy. [0004] In practical applications, since the wind rotor is located at a high place, it is easy to be attacke...
