Abstract
The utility model relates to an appearance-adjustable forming mold for a wind power vane, which comprises a bracing structure and an inner mold wall, and is divided into a fixed section and a variable section, wherein the fixed section corresponds to a section of a vane root; the variable section corresponds to a section of a vane tip; the variable section is bonded with a heat-conducting transition layer on the inner mold wall; and a second profile is laid above the heat-conducting transition layer. The appearance-adjustable forming mold for the wind power vane can produce the wind power vanes in multiple specifications, so that the manufacturing cost of the vane is lowered significantly, and the promotion and use are facilitated.
Description
Technical field
The utility model relates to the wind electricity blade of technical field of wind power generation and makes mould, particularly relates to a kind of wind electricity blade mould 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 configure the wind wheel blade of Multiple Type 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 the VARTM(vacuum assisted resin to shift die casting) explained hereafter manufacturing 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 (approximately 10%), has significantly increased the blade cost.
This shows, above-mentioned existing wind electricity blade mould obviously still has inconvenience and defective, and demands urgently further being improved in structure and use.How to found and a kind ofly produce the polytypic blade, thereby significantly reduce the wind electricity blade mould of the new adjustable profile of blade manufacturing cost, having become the current industry utmost point needs improved target.
The utility model content
The technical problems to be solved in the utility model provides a kind of wind electricity blade mould 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 utility model 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 lays the second profile above the heat conduction transition zone.
As a kind of improvement of the present utility model, the first profile that described mould inner wall comprises zone of heating and is laid on the zone of heating top.
Described zone of heating adopts the aluminium powder blending epoxy material of steel pipe support; Described the first profile and the 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 by adhering with epoxy resin above the first profile.
Described mould adopts the steel supporting construction.
Described supporting construction is formed by the steel square tubes soldering 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 by the thick binding agent of 7mm.
After adopting such design, the wind electricity blade mould of a kind of adjustable profile of the utility model utilizes a mold can produce the wind electricity blade of polytypic, thereby has significantly reduced the blade manufacturing cost, is more suitable for promoting the use of.
