Mould and its application method.
Background technology
A large amount of with non-renewable energy resources exhaust, and wind energy has huge as the pollution-free and reproducible new energy of one kind
Development potentiality, particularly to offshore islands, the outlying mountain area having inconvenient traffic, scarcely populated grassland pasture, and away from electricity
The also unapproachable rural area of net and at no distant date power network, borderland, as a kind of reliable approach for solving production and domestic energy, have
Highly important meaning；Even in developed country, wind energy is also increasingly subject to pay attention to as a kind of new energy of high-efficiency cleaning.
Wind-power electricity generation is to drive air vane rotation using wind-force, then lifts the speed of rotation through booster engine, makes hair
Electric installation generates electricity.Wherein, blade is a kind of important part, and it is broadly divided into two parts：Root of blade and blade body, leaf
Piece root is used to be connected with the rotating shaft of wind-driven generator, is made up of laying perfusion.
In the manufacturing process of existing wind power generation plant blade, the laying of root of blade can up to over one hundred layer, it is existing
Way：First, directly the laying of so multilayer is layered in blade mold together, irrigates together, so done two shortcomings：1
Laying is more, the fold that glass-fiber-fabric easily occurs during laying, influences the performance of whole blade；2nd, infusion time is longer,
Influence the production cycle of blade；
2nd, root of blade prefabricated-member mould is made, is partly laid on root of blade prefabricated-member mould and carries out, reduce in leaf
The workload of die, the mould still has following shortcoming：1st, mould structure is fixed, and manufactures the root of blade of different size
When, it is necessary to which different mould, causes to increase cost, and take the substantial amounts of confined space, inefficiency, it is necessary to waste a large amount of
Time be used for more mold exchange.
