Technical field
The wind electricity blade that the present invention relates to technical field of wind power generation is made mould, particularly relates to a kind of wind electricity blade mould and deformation method thereof of adjustable profile.
Background technology
Along with the development of modern wind generation technology, different wind power plants has different mean wind speeds and Limit of Wind Speed, and we are referred to as different wind regime.In order to adapt to different wind regime, can dispose the wind wheel blade of multiple model with a wind power generating set, thereby in the whole aeroelastic load of control, catch more wind energy, improve wind power generating set efficient.The blade of each model all has different length and aerodynamic appearance; Blades of large-scale wind driven generator generally adopts VARTM (vacuum assisted resin transfer die casting) explained hereafter to make moulding; Traditional blade forming mould all is the blade that a mold can only be produced single model; In the blade manufacturing cost, the mould cost accounts for significant proportion (about 10%), has significantly increased the blade cost.
This shows that above-mentioned existing wind electricity blade mould obviously still has inconvenience and defective, and demands urgently further improving in structure and use.How to found and a kind ofly produce the polytypic blade, thereby significantly reduce the wind electricity blade mould and the deformation method thereof of the new adjustable profile of blade manufacturing cost, having become the current industry utmost point needs improved target.
Summary of the invention
The technical problem that the present invention will solve provides a kind of wind electricity blade mould and deformation method thereof of adjustable profile, makes it can produce the polytypic blade, thereby significantly reduces the blade manufacturing cost, overcomes the deficiency of existing mold.
For solving the problems of the technologies described above; The wind electricity blade mould of a kind of adjustable profile of the present invention comprises supporting construction and mould inner wall, and described mould is divided into canned paragraph and variable field; Wherein: a section of the corresponding root of blade of canned paragraph, a section of the corresponding blade tip of variable field; Variable field is bonded with the heat conduction transition zone at mould inner wall, and above the heat conduction transition zone, lays second profile.
As a kind of improvement of the present invention, first profile that described mould inner wall comprises zone of heating and is laid on the zone of heating top.
The aluminium powder blending epoxy material that described zone of heating adopts steel pipe to support; Described first profile and second profile adopt the glass fiber reinforced epoxy resin material; Described heat conduction transition zone adopts aluminium powder blending epoxy material; Described heat conduction transition zone passes through adhering with epoxy resin above first profile.
Described mould adopts the steel supporting construction.
Described supporting construction is welded by the steel square tube of 100mm * 100mm or 80mm * 80mm.
Described canned paragraph accounts for 70% of mould total length.
Described heat conduction transition zone is adhered to the variable field inwall through the thick binding agent of 7mm.
In addition, the present invention also provides a kind of deformation method of wind electricity blade mould of above-mentioned adjustable profile, may further comprise the steps: according to the prefabricated heat conduction transition zone of blade shape construction and second profile; The variable field inner wall surface polishing of mould is crude; Smear binding agent at the variable field inwall; The prefabricated heat conduction transition zone and second profile are bonded on the variable field inwall; Binding agent is heating and curing.
After adopting such design, the wind electricity blade mould and the deformation method thereof of a kind of adjustable profile of the present invention utilize a mold can produce the wind electricity blade of polytypic, thereby have significantly reduced the blade manufacturing cost, are more suitable for promoting the use of.
