Abstract
The invention relates to a vacuum infusion exhaust setting of a wind power blade. The vacuum infusion exhaust setting comprises venting cotton on a flange of the wind power blade, winding pipes and vacuum openings, wherein the winding pipes are arranged on the venting cotton and wrapped by flow guide nets, and the vacuum openings are formed in a wind power blade mold. The vacuum openings are sequentially covered with three-layer structures of VAP semipermeable films, the venting cotton and the flow guide nets. The three-layer structures are connected to mold exhaust openings. The winding pipes, the flow guide nets and other materials with the good air guide effect are selected in the vacuum infusion exhaust setting of the wind power blade, so that exhaust efficiency is improved. According to the vacuum infusion exhaust setting of the wind power blade, most high-cost VAP films are omitted, and only few VAP films on the mold exhaust openings are reserved. Relative to a traditional exhaust setting, the material cost is reduced, the exhaust efficiency is improved, and the mold exhaust openings can be effectively prevented from being blocked by resin through the VAP film structure.
Description
Technical field
The present invention relates to a kind of wind electricity blade, more specifically, relate to a kind of wind electricity blade vacuum and pour into setting of bleeding.
Background technology
Wind electricity blade large-scale at present generally adopts vacuum perfusion process to make, and along with the increase of blade dimensions, the pumpdown time of blade is thereupon elongated with mode according to existing setting of bleeding, thus affects the production efficiency of whole blade.
For 56.9m blade, what adopt at present is ventilative cotton/flow-guiding screen/VAP film air extraction structure, and whole air extraction structure, around the peripheral flange of mould, covers mould inside bleeding point and bleeds.In this air extraction structure, VAP film has the function of ventilative resin thoroughly, so air can be through when can ensure to bleed, and resin can not be through.Simultaneously due to this characteristic of VAP film, cause the permeability of VAP more weak relative to other air guide material.In addition, VAP film is a kind of vacuum aided material costly relative to the auxiliary material of other vacuum.
Summary of the invention
For the technical problem of above-mentioned solution, in order to improve the pumping efficiency of whole air extraction structure, reduce the cost of vane manufacturing, the invention provides a kind of wind electricity blade vacuum and pour into setting of bleeding, this arranges and is optimized original air extraction structure and adjusts, eliminate most VAP film, and improve pumping efficiency.
In order to realize foregoing invention, the present invention adopts following technical scheme:
A kind of wind electricity blade vacuum pours into setting of bleeding, comprise the ventilative cotton being arranged on wind electricity blade flange place, the vacuum port being arranged on the winding pipe with flow-guiding screen parcel on described ventilative cotton and being arranged on described wind electricity blade, wherein said vacuum port place covers VAP pellicle, ventilative cotton and flow-guiding screen three-decker successively; Described three-decker is connected to mould bleeding point.
Further, described ventilative cotton quantity is two or more.
Further, the width of described ventilative cotton is 100mm.
Further, the quantity of described vacuum port is one or more.
Owing to adopting above technical scheme, beneficial effect of the present invention is:
1) wind electricity blade vacuum provided by the invention pours into setting of bleeding and chooses winding pipe, the material that the air guides such as flow-guiding screen are effective, improves pumping efficiency.
2) wind electricity blade vacuum perfusion provided by the invention is bled to arrange and is saved the more expensive VAP film of most of cost, only remains VAP film a small amount of on mould bleeding point, effectively prevent resin blocking mould bleeding point.
Accompanying drawing explanation
Fig. 1 is that the wind electricity blade vacuum of prior art pours into the structural representation of bleeding and arranging;
Fig. 2 is that wind electricity blade vacuum provided by the invention pours into the structural representation of bleeding and arranging;
Fig. 3 is the close-up schematic view at A place in Fig. 2.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, Fig. 1 be prior art wind electricity blade vacuum perfusion bleed arrange structural representation.As shown in the figure, place VAP pellicle/ventilative cotton/flow-guiding screen order in blade flange position three layers.Place wide 100mm above each mould bleeding point, the setting of bleeding of long 1000mm, and with sealing joint strip sealing, place the wide ventilative cotton of a 100mm from root of blade to blade tip along die flanging, ventilative cotton connection laying also covers mould bleeding point.
As shown in Figures 2 and 3, the present invention is directed to the original setting of bleeding of Fig. 1 and be optimized and adjust, eliminate most VAP film, and improve pumping efficiency.As shown in Figure 2, a kind of wind electricity blade vacuum provided by the invention pours into setting of bleeding, and comprises the ventilative cotton that two width being arranged on wind electricity blade flange place are 100mm, the vacuum port being arranged on the winding pipe with flow-guiding screen parcel on ventilative cotton and being arranged on wind electricity blade.As shown in Figure 3, vacuum port place covers VAP pellicle, ventilative cotton and flow-guiding screen three-decker successively, and mould is taken out mouth and is placed in the structure that covers and bleeds.
Wind electricity blade vacuum provided by the invention pours into setting of bleeding and chooses winding pipe, the material that the air guides such as flow-guiding screen are effective, improves pumping efficiency.
Wind electricity blade vacuum perfusion provided by the invention is bled to arrange and is saved the more expensive VAP film of most of cost, only remains VAP film a small amount of on mould bleeding point, effectively prevent resin blocking mould bleeding point.
The foregoing is only preferred embodiment of the present invention, be not used for limiting practical range of the present invention; If do not depart from the spirit and scope of the present invention, the present invention is modified or equivalent to replace, in the middle of the protection domain that all should be encompassed in the claims in the present invention.
