Integrated molding and manufacturing method of megawatt wind power cabin cover by pouring

Abstract

The invention provides an integrated molding and manufacturing method of a megawatt wind power cabin cover by pouring. The method comprises the following steps: designing a laying structure of a cabin cover according to the GL2010 standard via finite element software; then designing the position of an embedded part, a pouring pipe configuration chart and the position of vacuum consumable items by utilizing three-dimensional software; and then producing step by step according to the design. According to the invention, because a pouring technology is adopted to replace a manual pasting technology, the laying thickness is reduced, the laying efficiency is improved, and the using quantity of materials is reduced greatly; the production of a megawatt wind power cabin can be rapidly performed, and the development and implementation of novel wind power projects are facilitated; the operation environment of workers is improved.

Description

technical field [0001] The invention relates to a method for manufacturing a casing of a megawatt wind turbine cabin. Background technique [0002] The current method of manufacturing the nacelle casing in the wind power industry is mainly the hand lay-up process to make the nacelle casing. The above-mentioned manufacturing method has the following problems and shortcomings, which have a great impact on the quality of the produced nacelle casing: [0003] 1. The quality of the product is unstable, and the quality of the product is greatly affected by the operation of the workers. [0004] 2. The precision deviation of the product is relatively large, and the thickness deviation of the hand lay-up process is generally 20% [0005] 3. Rapid prototyping is not possible, the mold takes a long time, and the production cycle is long; [0006] 4. It has great environmental pollution and has a certain impact on the health of operators; [0007] 5. Many raw materials such as resin...
