Problems solved by technology

[0002] At present, in the production process of blades, the web is the main component of the composite wind turbine blade for wind turbines. The web structure is directly bonded to the blade shell with an adhesive. The bonding surface of the web is composed of a main bonding surface and an auxiliary bonding surface. , the main bonding surface is made of the flange edge of the web mold, but the auxiliary bonding surface is currently mostly bonded to the web with adhesive or hand-pasted with a baffle, and the accuracy of the bonding position and bonding angle is difficult to guarantee , and under the influence of the environment, it is difficult to guarantee the curing

Embodiment 1

[0024] Such as figure 1 Shown, a kind of preparation method of wind turbine blade web, it comprises the following steps:

[0025] a. First open a U-shaped hole in the glass fiber reinforced plastic movable rib (1);

[0026] b. According to the laying sequence of the web (2), lay the inner skin cloth, core material and outer skin cloth of the web, and lay the release cloth on the main adhesive corner area of ​​the web at the same time. When the release cloth is laid in this area, the web The main bonding surface and auxiliary bonding surface must be completely covered with release cloth; so as to ensure that the roughness of the main bonding surface and auxiliary bonding surface meets the requirements;

[0027] c. Place a silica gel plate (3) in the main adhesive area of ​​the web (2), and overlap the glass fiber reinforced plastic movable rib (1) with the main mold of the web (4) by 100mm;

[0028] d. Install the positioning block (5) according to the opening on the glass fi...

Abstract

The invention discloses a preparation method for a wind turbine blade web of a wind turbine generator set. The preparation method comprises the steps that according to the layer laying order of the web (2), an inner web skinned cloth, an outer web skinned cloth and a core material are laid, and meanwhile, a release cloth is laid in a main adhering corner area of the web; a silica gel board (3) is placed in a main adhering area of the web (2), and a glass fiber reinforced plastic movable blocking flange (1) is in lap joint with a web main body mold (4); according to a hole in the glass fiber reinforced plastic movable blocking flange (1), a locating block (5) is installed; and a fiber cloth is laid on an adhering-connection face of the web (2), then a web pouring system is laid, a vacuum system is built, and vacuum integral pouring is conducted to obtain the web. The preparation method is reasonable in process design and high in operability. An integral pouring forming process is adopted, rigidity smooth transition of the blade web and a shell adhering-connection face is facilitated, uniform scrape coating of adhesive is facilitated, and defects caused by out-of-tolerance of adhering-connection of the web can be reduced greatly. The prepared I-shaped web is high in precision and practicability.

Description

technical field [0001] The patent of the present invention relates to a preparation method of a wind turbine blade accessory of a wind power generating set, in particular to a preparation method of a web of a wind turbine blade web of a wind power generating set. Background technique [0002] At present, in the production process of blades, the web is the main component of the composite wind turbine blade of the wind turbine. The web structure is directly bonded to the blade shell with an adhesive, and the web bonding surface is composed of the main bonding surface and the auxiliary bonding surface. , the main bonding surface is made by the flange edge of the web mold, but the auxiliary bonding surface is currently mostly bonded to the web with adhesive or hand-pasted with a baffle, and the accuracy of the bonding position and bonding angle is difficult to guarantee , and under the influence of the environment, curing is difficult to guarantee. [0003] Therefore, on the ba...
