Function, is fully heating and curing to structure glue, lifts the repairing quality of product.
To realize the purpose of the present invention, the technical solution adopted in the present invention is：A kind of heating of wind electricity blade maintenance, plus
Pressure device, including heating, increased pressure board, external power source, the external power source are that the heating, increased pressure board are powered, the heating, plus
Pressing plate is two pieces, is respectively arranged at the pressure face of wind electricity blade and the side of suction surface, and both are clamped to viscous by pressing means
Pressurizeed in direct type face.
Compared with prior art, the invention provides heating, increased pressure board, external power source structure, apply gluing in restoring area
After connecing, heated with two pieces of heating, this pair of restoring area of increased pressure board, pressurizeed, not only ensured the profile after repairing, and pass through
Its heating function for carrying, is fully heating and curing to structure glue, lifts the repairing quality of product, is easy to industrially be promoted
And application.
Brief description of the drawings
Fig. 1 show the structural representation of the embodiment of the present invention；
In figure：1- external power sources, 2- temperature control systems, the external frameworks of 3-, 4- heating, increased pressure board, 5- locking pressurization spiral shells
Bolt, 6- guide posts, 7- wind electricity blades.
Specific embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that described herein
Specific embodiment be only used to explain the present invention, be not intended to limit the present invention.
It should be noted that " connection " described herein and the word for expressing " connection ", such as " being connected ",
" connected " etc., it both may refer to a certain part and had been directly connected to another part, it is also possible to refer to a certain part by other portions
Part is connected with another part.
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can phase
Mutually combination.
As shown in figure 1, being the specific embodiment of the application, after wind electricity blade 7 carries out vertex-gluing graph, the application is integrally filled
Put and be promoted to reparation position, pulley connecting steel wire ropes are hung by wind turbine nacelle, steel wire rope is connected with external framework 3, using leading
To bar 6, pressurization, heating plate 4 are moved to blade and repair surface, two pieces of pressurizations, heating plates 4 are locked, given by locking pressurization bolt 5
Wind electricity blade 7 provides pressure, and after wind electricity blade 7 is clamped, opening temperature control system 2 sets associated heat temperature and heating
Time, after structure glue fully solidifies, by setting program temperature control or manually powered off.
It should be noted that present invention is mainly used for the cementing cracking of blade and the maintenance of blade bulge, it can also be used to leaf
Piece carries out technological transformation in outer surface using bonding mode.Two pieces of pressurizations, pressing means of heating plate 4 can also utilize fixture by blade two
Face is clamped.Cause the change of blade aerodynamic profile present invention mainly solves non-pressurised reparation, pressurizeed using the type face of frock
Function can make blade restore to the original state；In addition, using the heating function of frock, can effectively solve because material heats insufficient, glass
Failure is repaired caused by glass transition temperature value is relatively low.The quality that product is repaired can be significantly improved using the present apparatus.In addition, foundation
The present invention, can effectively lift blade carries out the product quality of technological transformation using external technique for sticking.
Specifically, the blade external form that pressurization, the in-profile shape of heating plate 4 are repaired together is basically identical, or with reparation
Sheet material, repair cavity external form profile it is basically identical；The type face consistent for shape contour, can carry out rebuilding the pressurization in replica face
And heating.Its pressurization and heated perimeter can cover the region of the smearing of overall structure glue, also can with due regard to medium conductivity of heat
Can, heated perimeter is suitably reduced.
Specifically, wind electricity blade reparation or technological transformation is to use structure glue technique for sticking by blade body reparation or use knot
With repairing sheet material or cavity be bonded blade body by structure glue sticking technique.And repaired or skill in blade outer surface
Change.
Specifically, resistance wire is embedded into pressurization, inside heating plate 4, can one of which heating plate or two heating
Set on plate, continuous heating is carried out to gluing of surfaces.
Specifically, external framework both sides are the suction surface and pressure face for corresponding to blade, set two pieces of heating increased pressure boards,
On heating increased pressure board, pilot hole is set, heating, increased pressure board can be slided by the guide post of connection on framework to the direction of blade.
For the heating on blade, the less region of pressurization scope, negligible this external framework.Directly using two pieces of heating increased pressure board folders
Tightly it is fixed on blade.
Specifically, heating, increased pressure board make on blade core rod, or make mould to the theoretical external form after restoring area reparation
After core, then make heating increased pressure board.Its method is：Composite is laid on core rod, heating wire, and thermocouple is re-layed.
Finally lay related enhancing, the material of insulation.
Specifically, temperature control system, by thermocouple collecting temperature data, and feeds back to temperature controller, temperature control
Device processed is used for the difference for judging to set temperature and actual temperature, determines the size of electric current.When heating timer is used to set heating
Between, when heated between reach after, whole heating system is powered off.Preferably, can be used and preferably use temperature programmed control system
System.Automatically control heating schedule and power-off.
Specifically, structure glue type described herein is including but not limited to epoxy structural rubber, vinyl saturation or not
The structure glue materials such as saturated structures glue, polyurethane structure glue.Reparation or technical reform scheme for blade are entered in blade outer surface
Row operation.Heated perimeter can cover the scope of the smearing of overall structure glue；Or the heat transfer of consideration medium, heated perimeter can be slightly
Less than the smearing scope of structure glue.
Specifically, heating-up temperature is usually arranged as structure adhesive curing preferable temperature, the material that can be provided according to material supplier
Material operation instructions are set, and also dependent on the use environment of the present apparatus, can in advance to simulate that carry out at a temperature of external field environment experiment right
Warm-up time and temperature setting are optimized.
Specifically, the material of described external framework is metal or nonmetallic composite.Preferably use metal material
Rigidity is provided to whole device.
Specifically, pressurization, heating plate are made using composite.In the pre-buried heating wire of composite inner, thermoelectricity
It is even.Preferably：Heating wire spacing is 10~20mm；The position of thermocouple is arranged on heated center position.
The above is only the preferred embodiment of the present invention, it is noted that for the common skill of the art
For art personnel, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications
