Embodiment Construction

[0039] In the following, the present invention will be described in detail with reference to the accompanying drawings and specific implementation examples. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. After reading the present invention, those skilled in the art all fall into the appended claims of the present application to the amendments of various equivalent forms of the present invention limited range.

[0040] figure 1 It is an integrated drawing of positive pressure assisted vacuum perfusion integrated molding adopted in the present invention. The female molds 1 and 21 provide the molds for producing the upper and lower shells of the blades. During the blade manufacturing process, the mold trusses and the positioning and locking devices on the sides of the molds are fastened together to form a whole. The molds contain water heating or electric heating. ...

Abstract

The invention relates to an integrated formation device and an integrated formation method for a horizontal shaft wind power blade. The device comprises a vacuum pumping system, pressurizing equipment, a resin defoaming system, a resin supply system and a resin collecting system. When the wind power blade is manufactured, integrated formation is realized by a positive pressure auxiliary vacuum perfusion mode, so that the defects of the traditional vacuum perfusion process are overcome, the blade-formation product quality is improved, and various disadvantages and risks caused by that the traditional process shell adopts adhesive to adhere are avoided.

Description

technical field [0001] The invention relates to an integrated forming device and method for wind power blades, which belong to key components of wind power generation equipment. Background technique [0002] With the increasingly prominent energy and environmental issues, wind power, as a clean energy and renewable energy, has received global attention and attention. With the investment in research and development in various countries, wind power technology has also made great progress, and the capacity of single wind turbines has continued to increase. From the initial kilowatt level to today's multi-megawatt level, the blade length has also increased from a few meters to more than 80 meters at present. At present, the longest blade commercialized has reached 61.5 meters, and larger and longer blades are also under development. Large-scale has become an inevitable trend, but the transportation problems and high freight costs are unbearable. [0003] The existing methods ...
