Description
Technical field
The utility model relates generally to wind electricity blade production technology, in particular to a kind of invalid bonding glue amount
Less wind electricity blade.
Background technique
MW grades of wind electricity blades are generally made of main beam cap, anti-shearing web, covering and the several major parts of blade root fastenings part.
Usually by one, each web and covering or main beam cap is bonded after web and each self-forming of covering, there are two bonding plane, double abdomens
Plate leaf piece will generate four bonding planes.When bonding, in order to exclude air, bonded adhesives is made to fill up bonding gap, bonded adhesives applying amount
It is greater than bonding gap area of section, can then generates some invalid bonded adhesives.Therefore, bonding plane is more, and invalid bonded adhesives is used
It measures more.
Cost declining has become wind electricity blade development trend.The Chinese patent and Publication No. of Publication No. CN1656313A
The Chinese patent of CN102889184A simplifies the connection of web and covering by girder and web integral structure, by every abdomen
Two bonding interfaces of plate are reduced to a bonding interface, have saved bonded adhesives.The Chinese patent of Publication No. CN102889184A
There is the flanged plate perpendicular to web plane direction to increase adhesion width or bond area as above-mentioned patent in abutting edge.It awards
The Chinese patent that power notification number is CN101905538B is, saving integrally formed with shear web side bonding angle and covering
Bonded adhesives.
The Chinese patent that the Chinese patent and patent publication No. of Publication No. CN1656313A is CN102889184A solves
The problem of one web two bonding planes, reduce bonded adhesives dosage.Since web abutting edge is primarily subjected to shear stress effect,
Therefore under bonded adhesives volume or glue consumption same case, adhesion width is bigger, and person's stress is lower.There is bonding in the two patent
Thickness the factors such as is affected by molding gap, by taking bonded adhesives volume V=80 (width mm) * 5 (thickness mm) as an example, when thickness increases
When adding 1mm, isometric bonded adhesives adhesion width will reduce by more than 13mm.For the MW of ten meters of blade root diameter numbers meter of length number
Class large power wind electricity blade, even if molding gap changes in predetermined tolerance size, the bonding plane width of unit volume bonded adhesives
Increase and decrease is also that should not be underestimated, and it is bigger that bonded adhesives dosage controls difficulty.
Authorization Notice No. is in the Chinese patent of CN101905538B, and web is placed directly on covering layer of cloth, is put when for the first time
When setting not in place, the movement of web contact surface, which will pull glass cloth, makes its dislocation.Secondly, bonding angle mold and covering die exist
Intrinsic relative tolerance will form resin-rich layer between two type faces, and certain loss is had in cost, and when rich resin is blocked up pair
Fatigue strength also has certain influence.
