Description
Technical field
The utility model is related to technical field of wind power generation.
Background technology
Wind electricity blade plays very important effect in wind generating technology, by development for many years, wind-power electricity generation skill
Art development is maked rapid progress, and the progress of wind electricity blade technology also proposes more requirements to technique, as blade the more does the more big,
Pre-buried type blade is compared with punching type blade, has good blade root fastenings intensity, therefore most of large-scale blades all use in advance
Bury type structure.
Precasting process is a kind of novel process, can increase substantially production efficiency, eliminates blade root wrinkle defect, drop
The holding time of low master mold has become a kind of trend of blade production at present.Blade root is primarily subjected to as wind electricity blade
The quality at power and position, blade root has the quality of blade important influence, performance to directly affect the service life of blade, because
This, the precasting process technology of blade root becomes the hot spot of all blade manufacturers research.
Comparative maturity, industry Nei Ge enterprises more or less have using one punching type blade root prefabricating technique at present
The technology of fixed blade root precasting process, but pre-buried type structure is just few compared to punching type quantity itself, and use blade root prefabricated
It is then less, therefore the pre-buried type blade prefabricating technique of most domestic producer is still in the exploratory stage at present.
The structure of existing pre-buried type blade, blade root are usually divided into two semicircles, and in semi-circular structure the inside laying by
Exterior skin, part A successively decrease layer, built-in fitting, part crossbeam, part B successively decrease layer, inside panel constitute.Leaf and root structure is from outside to inside
It is as follows to form order：Exterior skin → part A layer → built-in fitting → crossbeam → part B of successively decreasing is successively decreased layer → inside panel.
Existing prefabricated blade root ply angles, ply stacking-sequence does not make big adjustment, but implements in engineering at the scene, it may appear that such as
Lower problem, leads to Difficulty：First, during secondary laying, some part As successively decrease layer and exterior skin is required to be taken
Processing is connect, is locally had an impact in molding gap to leaf root part；Second, it is inevitable because largely being overlapped using program needs
Lead to the increase of leaf weight；Third, this method need stringent control, production to live laying job requirements height, overlap joint size
Scribing line operation must be used, for the raising unobvious of production efficiency, product is influenced bigger by the level of production operation personnel.
As it can be seen that existing prefabricated blade root ply angles have field conduct difficulty, cause pre-buried type blade prefabricated
Non- prefabricated advantage is failed to embody.Existing pre-buried type wind electricity blade blade root prefabrication process, there are prefabricated component molding is tired
Difficulty, location difficulty in forming process, is easily deformed, it is difficult there are laying during secondary laying after molding the problems such as, cause
Prefabricating technique fails to be promoted.
In the prior art, application No. is a kind of MW class wind turbine blades of the disclosure of the invention of CN201310398079.3
The pre-formed technique of blade root, processing step are：First blade root prefabricated component glass-fiber-fabric is laid on blade root prefabricated-member mould, then
Again priming by vacuum, be heating and curing molding, finally the blade root prefabricated component after curing molding is called in main mould and is integrally formed.Above-mentioned side
Case key protection point is a kind of blade root precasting process method, and the auxiliary material of instillation process, laying, moulding process etc. are all made
It clearly requires, but between the ply angles to the blade root prefabricated component of wind electricity blade, prefabricated component and secondary laying glass-fiber-fabric
The key factor of the prefabricating techniques such as linking, is not directed to.Application No. is a kind of wind of the disclosure of the invention of CN201710682158.5
Electric blade root structure includes the ontology of fibre reinforced composites, and ontology forms leaf and root structure shape, and wraps inside
