The rear end of bolt set or the exhibition of blade are filled to commonly using core material, in the left and right of bolt sleeve commonly using pultrusion
Glass fiber reinforced plastic shapes.Bolt sleeve up and down or the thickness direction of blade root, it is multiple using three axial glass fiber reinforcements of big thickness
Condensation material or uniaxially and biaxially alternate glass fibre reinforced composion.The design of some roots of blade, in blade
Thickness direction, that is, the top or lower part of bolt sleeve, unilateral side has used the core material of irregular shape.Existing pneumatic equipment bladess
The above-mentioned design of root, due to up and down or on the thickness direction of root of blade, not used using core material in bolt sleeve
Pure glass fibre reinforced composion or core material using a small amount of unilateral irregular shape, cause root of blade quality compared with
Weight.
Utility model content
For the disadvantages mentioned above and deficiency of the prior art, the utility model is intended to provide a kind of large scale wind power machine root of blade
Ply angles, by the grammes per square metre of the glass fibre of reasonable distribution root of blade all directions, even with the higher glass of modulus
Glass fiber reduces whole glass fibre reinforced composion in the usage amount of blade root, and in a thickness direction, i.e., in bolt sleeve
Up and down, respectively using certain equal thickness core material fill, both alleviated the weight of blade root, in turn ensure blade root thickness and just
Degree.
The technical scheme adopted by the utility model for solving the technical problem is:
A kind of ply angles of large scale wind power machine root of blade, including at least substantially along root of blade pitch-line direction
Even spaced apart multiple bolt sleeves, the periphery of each bolt sleeve are wrapped up glass fibre, are set between adjacent two bolt sleeve
The glass fiber reinforced plastic shapes of pultrusion are set, the bolt sleeve and glass fiber reinforced plastic shapes collectively form bolt jacket layer, which is characterized in that
The outside of the bolt jacket layer be sequentially arranged from inside to outside the second fiber glass reinforcement layer, uniform thickness distribution the
One core layer and it is arranged in outermost first fiber glass reinforcement layer,
The inside ecto-entad of the bolt jacket layer be sequentially arranged third fiber glass reinforcement layer, uniform thickness distribution the
Two core layers and the 4th fiber glass reinforcement layer for being arranged in innermost layer,
First core layer, the second core layer carry out chamfered transition to core material near the molding gap of blade, and
The lapped layup transitional glass fibrous material in chamfered transition area.
Preferably, the thickness of first core layer and the second core layer is identical or different.
Preferably, first core layer, the core material in the second core layer are equipped with fluting and/or hole.It is subsequent to make
Vacuum introducing technology it is more smooth.
Preferably, first core layer, the core material in the second core layer are BALSA wood, PVC or PET.
Preferably, first core layer, the second core layer splice shape by the core material block that multiple arrays of uniform thickness are arranged
At.
Preferably, the ply angles pass through final curing molding after vacuum importing resin.
Compared with the existing technology, the ply angles of the large scale wind power machine root of blade of the utility model, change traditional
The technique that the interior outside of bolt jacket layer all uses glass fibre to be covered in root of blade laying, by bolt jacket layer
Fiber glass reinforcement respectively is greatly reduced using certain thickness and the lighter core layer of material on interior outside thickness direction
Usage amount, to effectively reduce the quality of root of blade；It is laid between first and second core layer and bolt jacket layer certain thickness
Fiber glass reinforcement avoids being deteriorated using bolt sleeve adhesive property caused by core material；Near molding gap, core material is used
Oblique angle and scrim cloth overlapped method can guarantee the reliability of vane mold matching bonding.
Detailed description of the invention
