Description
Technical Field
The utility model belongs to the technical field of the honeycomb duct technique for vacuum infusion and specifically relates to a prevent indentation omega honeycomb duct suitable for wind-powered electricity generation blade vacuum infusion in-process resin drainage.
Background
The production and manufacturing method of the wind power blade mainly comprises the steps of carrying out vacuum infusion molding on a composite glass fiber reinforced plastic fiber material, and carrying out vacuum infusion after sequentially laying a reinforcing material, demolding cloth, a flow guide net and a flow guide pipe on a blade mold. The design structure of the flow guide net and the flow guide pipe and the arrangement of the filling channel in the vacuum filling of the wind power blade are very important, and the gum dipping speed and quality of the whole blade and the distribution uniformity of resin in the flow guide net are directly influenced.
At present, the honeycomb ducts used in the flow guide network are mainly circular honeycomb ducts, the focus is at the distribution position of the honeycomb ducts, the using quantity of the honeycomb ducts is neglected, the influence on the design structure of the honeycomb ducts and the waste amount of residual resin in the honeycomb ducts is neglected, meanwhile, although the omega honeycomb ducts easily enable resin liquid to rapidly seep out due to the middle omega-shaped gap door, the contact area between two sides of the omega-shaped honeycomb ducts and the surface of a blade is small, and indentation is generated after the resin liquid is solidified because the pressure of 0.1MPa is always kept in the vacuum infusion process. In order to reduce the residual resin in the draft tube, a solution is to add a double-layer sealing lining film on the inner wall of the draft tube, but the generated problems are that the film is punctured and pollutes the resin after the resin is cured, and meanwhile, the cured resin is necessarily remained on the film of the filler, so that the secondary recycling is unavailable, more waste products are generated, and resources are wasted.
