Problems solved by technology

[0003] The rapid development of the wind power industry poses a severe challenge to the production cost of blades. Optimizing the production process of blades is the main way to reduce the cost of blades. At this stage, in the entire web production process, the amount of glue used for infusion resin is large, and the amount of auxiliary materials is wasted. , the production cost of the web is high, and at the same time, the existing vacuum infusion method for web production is prone to cause defects such as discoloration of the web core material, collapse of the flow channel, and indentation, and the high maintenance cost of the blade web leads to high production costs of the entire blade. No competitive advantage in the blade production industry

[0027] EXAMPLES: Take 59.5 wind power blade web production as an example

[0028] (1) Preparation: Confirm the temperature of the workshop before operation, the humidity is in line with the process requirements, the temperature range is 16-30 ° C, the humidity range is 20% -80%, and the number of fiberglass and PVC sheets, the specification, model, and production batch number are in accordance with production. Require, prepare the buffer can, vacuum pump, mold, visual inspection of the entire mold surface, if there is unevenness, deformation, deformation, etc., it is reported that the management is organized and processed, and then the next step, confirmed the buffer can The vacuum port of the vacuum pump is no blocked. If there is a plug, it is necessary to use electric drill drilling. Use the electric drill to ensure that the drill bit is perpendicular to the vacuum hole. During the drilling process, the mold equipment cannot be hurt, and the residual foreign matter of the mold ...

Abstract

The invention discloses a unilateral pouring method for the web of a wind power blade, which comprises mold preparation, laying of the lower layer of release cloth, laying of the lower layer of the sheet, laying of the PVC sheet, laying of the upper layer of the sheet, laying of the lightning protection wire, preheating of the mold, Laying of the upper layer of release cloth, laying of auxiliary materials, vacuum infusion, solidification of the web, and finally the production of the web, wherein, in the process of laying the auxiliary materials, it is segmented from the blade root to the blade tip at the side of the outer edge of the mold Lay the spiral pipe, lay the flow channel from the blade root to the blade tip on the other side of the outer edge of the mold, and lay the diversion net under the flow channel. At the same time, the spiral pipe is sealed and connected to the buffer tank, and the buffer tank is sealed to connect the vacuum pump. The spiral tube is placed on one side of the mold, and the spiral tube is connected to the buffer tank through the vacuum tube, and the buffer tank is connected to the vacuum pump. The spiral tube replaces the vacuum device on the original mold, reducing the consumption of the more expensive steel wire spiral tube. The road is laid in sections, which saves the amount of auxiliary materials and reduces the production cost of the web.

Description

Technical field [0001] The present invention belongs to the technical field of wind power blade, and is specifically involved in a single-edge perfusion method of wind power blade web. Background technique [0002] With the gradual exhaustion of traditional fossil energy such as coal, oil, natural gas, the development and utilization of new energy such as wind energy and solar energy is increasingly attacked, and it has become one of the most commercial promotion prospects in the energy field. Currently Domestic and foreign developed rapidly. Wind power generation has grown rapidly in our country, which is equally hot in the world. In the next few years, the world's large fan market will grow at 20% per year, and China's growth rate will be faster. According to statistics, between 2006 and 2010, my country's wind power blade demand was approximately 7,000 pieces. In 2011, in 2020, my country's wind power demand is expected to reach 50,000 pieces, and the huge market prospects mak...
