Embodiment 1

[0038] Such as figure 1 and figure 2 As shown, a method for preparing a wind turbine blade internal reinforcement pre-laying perfusion, comprising the following steps:

[0039] A. Lay the inner vacuum film 2, the flexible heating mold 5, the continuous felt 4 and the outer reinforcing fiber cloth 3 sequentially on the protrusion of the rigid mold 7; Lay the outer vacuum film 6 on the reinforcing fiber cloth 3, and bond the outer vacuum film 6 with the first sealing strip 1 to achieve sealing;

[0040] B. Connect the continuous mat 4 with the spiral tube 8 as a vacuum pumping system, and vacuumize and compact the inner reinforcing fiber cloth 3;

[0041] C. After the vacuum is qualified, the whole system is docked with the blade leading edge 11, and the inner vacuum film 2 is removed after the docking, so that the outer reinforcing fiber cloth 3 is firmly attached to the blade leading edge 11;

[0042] D. Connect the continuous felt 4 to the injection pipe 9; then the flexi...

Embodiment 2

[0046] Such as image 3 and Figure 4 As shown, a method for preparing wind turbine blade external reinforcement vacuum infusion, comprising the following steps:

[0047] A. Lay the outer vacuum film 6, the flexible heating mold 5, the continuous felt 4 and the outer reinforcing fiber cloth 3 sequentially in the groove of the rigid mold 7; The inner vacuum film 2 is laid on the reinforcing fiber cloth 3, and the inner vacuum film 2 is bonded with the first sealing strip 1 to realize sealing;

[0048] B. The continuous felt 4 is connected with the spiral tube 8 as a vacuum pumping system, and the external reinforcing fiber cloth 3 is vacuumed and compacted;

[0049] C. After the vacuum is qualified, the whole system is docked with the blade leading edge 11, and the outer vacuum film 6 is removed after the docking, so that the inner reinforcing fiber cloth 3 is firmly attached to the blade leading edge 11;

[0050] D. Connect the continuous felt 4 to the injection pipe 9; the...

Abstract

The invention discloses an internal and external reinforcing pre-paving perfusion preparation method of a wind turbine generator set wind wheel blade. The internal and external reinforcing pre-pavingperfusion preparation method comprises an internal reinforcing pre-paving perfusion preparation method and an external reinforcing pre-paving perfusion preparation method. The internal reinforcement and the external reinforcement are integrally poured and molded with a shell, so that the internal and external reinforcing bonding performance of the blade is better, the internal and external reinforcing surface is more smooth, and the follow-up performance is greatly improved; and the integral surface effect of the blade can be greatly improved, and then is heated through a flexible heating dieafter being subjected to vacuum perfusion, so that the manufacturing efficiency of internal and external reinforcementcan be greatly improved, the curing quality of the internal and external reinforcementis guaranteed, finally the purpose of precision production is achieved, and compared with the prior art, a good technical effect is realized.

Description

technical field [0001] The patent of the present invention relates to a method for preparing a structure of a wind turbine blade of a wind power generating set, in particular to a method for preparing the inner and outer reinforcement pre-laying of the wind turbine blade of a wind power generating set. Background technique [0002] At present, in the production process of blades, the internal and external reinforcement of the shell is generally prepared by hand lay-up vacuuming process or vacuum infusion process. The hand lay-up vacuum process has defects such as whitening of internal and external reinforcement, many burrs, and wrinkles; the vacuum infusion process has defects such as indentations and wrinkles left by the auxiliary materials. After the two kinds of perfusion, post-curing is required. After-curing generally uses auxiliary equipment such as electric blankets and oven lamps. This curing method is inconvenient to control the curing temperature, and the heating e...
