Manufacturing method of sandwich-structure glass steel cabin cover

Abstract

The invention discloses a manufacturing method of a sandwich-structure glass steel cabin cover. The method comprises the following steps: paving glass fibers, a foam board and glass fibers on a mold; paving a demolding cloth layer on the surface of the glass fibers; paving a diversion net layer on the demolding cloth; paving a diversion pipe on the diversion net; paving a vacuum bag on the diversion pipe; starting a vacuum system which exhausts air in the mold cavity so as to form a negative pressure with vacuum degree of 90% in the mold cavity; introducing special resin into vacuum by means of the negative pressure, and pressing the resin into the fiber layer through the pre-paved diversion pipe, so that the entire mold is fully filled with the resin soaked and reinforced material; curing the cabin cover; removing the vacuum bag; and demolding the cabin cover from the mold. The method disclosed by the invention has the advantages of simple manufacturing process, low cost and short construction time, improves the pressure resistance and toughness of the cabin cover, enhances the thermal insulation performance, and prolongs the service life, thereby achieving high social and economic benefits.

Description

technical field [0001] The invention relates to a protective device for a wind power generator, in particular to a method for manufacturing a glass fiber reinforced plastic nacelle cover with a sandwich structure. Background technique [0002] As the protective cover of the wind turbine, the FRP nacelle has been eroded by natural wind, rain, snow and sunlight for a long time. , and it is necessary to strictly control the weight of the nacelle cover. [0003] At present, the wind turbine canopy adopts all-glass steel structure. Under the condition of weight limitation, the thickness design of the nacelle cover is limited. Generally, the thickness of the nacelle cover is about 8mm, which is insufficient in rigidity and easy to deform. Reinforcement ribs are mainly used to increase the rigidity of the shell. , The construction process is complex and the work intensity is high. Contents of the invention [0004] Purpose of the invention: Aiming at the deficiencies of the pri...
