Embodiment 1

[0025] Such as figure 1 Shown, a kind of preparation method of the wind turbine blade with aluminum point, it comprises the following steps:

[0026] a. Design the aluminum tip 3 dovetail structure;

[0027] b. According to the structure at the dovetail of the aluminum tip 3, wind the unidirectional carbon fiber yarn 5; fill the unidirectional carbon fiber yarn 5 with the chord groove 4 at the dovetail of the aluminum tip 3, and ensure that there is no metal exposure at the dovetail;

[0028] c. Place the aluminum tip 3 wrapped with the unidirectional carbon fiber yarn 5 on the SS surface shell structure layer 1;

[0029] d. Place a silicone male mold 6 at the dovetail of the aluminum tip 3 wound with a unidirectional carbon fiber yarn bundle 5, so as to avoid resin-rich around the aluminum tip 3;

[0030] e. Establish a vacuum system;

[0031] f. Vacuumize and infuse the dovetail of the aluminum tip 3 in a vacuum. After the dovetail of the aluminum tip 3 is poured, it is s...

Abstract

The invention discloses a preparation method of a wind generating set wind turbine blade with an aluminum tip. The method comprises the steps that a dovetail structure of the aluminum tip (3) is designed, then a one-way carbon fiber yarn bundle (5) is wound, a silica gel male die (6) is put on the one-way carbon fiber yarn bundle (5), and the aluminum tip and an SS face shell structure layer (1) are bonded through vacuum infusion; and then bonding glue (7) is prepared on the other bonding face of the dovetail position of the aluminum tip (3) in a scraping manner so as to guarantee bonding of the aluminum tip (3) and a PS face shell structure layer (2). According to the preparation method, process design is reasonable; operability is high; infusion forming of the aluminum tip and the blade is achieved; bonding of a shell and the aluminum tip is facilitated; lean production of the blade can be achieved easily; the defect of aluminum tip non-follow-up bonding can be reduced greatly; the prepared aluminum tip of the wind turbine blade is high in precision and high in practicality; and a good technical effect is achieved.

Description

technical field [0001] The patent of the invention relates to a preparation method of a lightning protection system for a wind turbine blade of a wind power generating set, in particular to a preparation method of a wind turbine blade with an aluminum tip. Background technique [0002] In the current blade production process, the aluminum tip is installed in the mold clamping process. First, the aluminum tip is bonded to the SS surface with an adhesive. After the adhesive is cured, the adhesive is scraped on the PS surface of the aluminum tip to finally complete the installation process of the aluminum tip. The aluminum tip is bonded to the SS surface with an adhesive. When the adhesive is not fully cured, the aluminum tip is very easy to slide, which brings hidden dangers to the bonding quality of the aluminum tip. At present, the pressing tool is often used to fix the aluminum tip. , easily damaged. Contents of the invention [0003] Purpose of the invention: The purpos...
