Description
Technical field
The utility model relates to wind power generation unit blades to protect field, more particularly to a kind of surfacecti proteon knot of wind electricity blade
Structure.
Background technique
In recent years, the pollution-free industry that wind-power electricity generation develops as state key, is rapidly developed.Wind Power Generation Industry tend to
Low wind speed, marine wind field development, therefore wind electricity blade becomes greatly, maintenance cost is also higher and higher.Blade maintenance frequency highest
Be that blade shows skin of paint, the especially leading edge in wind cutting face, because its often by rainwater, dirt sand etc. impact and wear, easily by
To damage.The destruction of blade surface protective coating, directly affects the aeroperformance of blade of wind-driven generator, to influence blower hair
Electrical efficiency.If blade surface coating loses defencive function, directly results in exposed blade glass steel substrate and corroded, thus
Influence blade construction safety.To reduce blade maintenance cost, be bound to blade shields grade to be improved, and improves blade paint performance
And service life.
The traditional defense system of blade of wind-driven generator is usually that high concentrations of toluene diisocyanate adds gel coat system, for blade inlet edge meeting
Increase the preferable leading edge protection paint of wearability or gel coat or the preferable leading edge of wearability protects polyurethane film.Paint or
Gel coat needs to guarantee that coating has enough thickness in coating process, but in actual production process, blade coatings are not able to satisfy leaf
Protection requirements in piece operational process, if crackle easily occurs for overweight coating, coating is easy to fall off, so that it is coarse to influence blade surface
Degree；If protection effect, especially blade portion is not achieved in cover light, coating is relatively thin, and protection effect cannot be guaranteed.Leading edge protection
Although film can ensure that thickness is uniform, leading edge protective film difficulty of construction is larger, and difficult in maintenance, it is outermost that protective film is attached to blade
Layer, resistance to UV aging is poor, increases blade maintenance difficulty.
To sum up, the problem of existing blade shields system is protected there is no very good solution blade surface, it is accordingly required in particular to anti-
The blade inlet edge surface of shield, is not also protected well.In view of above-mentioned technological deficiency, the utility model is founded a kind of new
The surface protective structure of wind electricity blade can reduce blade surface roughness, blade surface wearability be improved, to improve leaf
Piece degree of protection reduces blade maintenance cost, improves the reliability of leaf product.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of surface protective structures of wind electricity blade, can reduce
Blade surface roughness improves blade surface wearability, improves blade shields grade, blade maintenance cost is reduced, to overcome
The deficiency of existing wind electricity blade surfacecti proteon system.
In order to solve the above technical problems, the utility model provides a kind of surface protective structure of wind electricity blade, the protection
Structure successively includes top coat layer, prime coat, aramid fiber composite material layer and putty layer from outside to inside, and the putty layer is applied directly to
On the outside of the blade shell of the blade.
It is further improved, the aramid fiber composite material layer is using aramid fiber, long aramid fiber, aramid paper or the aramid fiber of being chopped
Woven cloth.
It is further improved, the thickness of the thickness of the aramid fiber composite material and the priming paint and finishing coat and close.
It is further improved, the thickness of the aramid fiber composite material is less than 1mm.
It is further improved, the wind electricity blade is blade whole body or blade inlet edge position.
It is further improved, the wind electricity blade is blade inlet edge position of the blade maximum chord length at blade tip.
By adopting such a design, the utility model at least has the following advantages:
1, the utility model can improve blade paint table by increasing by one layer of aramid fiber composite material in blade paint layer lower part
The wear-resisting property in face improves the abrasive resistances such as anti-weathering, the sand erosion of blade surface, while improving the use of wind power generation unit blade product
Service life and cost-effectiveness reduce blade maintenance cost, guarantee the generating efficiency of Wind turbines.In addition, because aramid fiber composite material has
There is high flame-retarding characteristic, the security against fire of wind electricity blade can also be improved.
2, the utility model blade surface safeguard structure can be used for blade whole body, it can also be used to which blade inlet edge part is improved
The protective capability of blade inlet edge.
3, the utility model blade surface safeguard structure also reduces surface roughness, to improve blade surface anti-pollution energy
Power.
Detailed description of the invention
Above-mentioned is only the general introduction of technical solutions of the utility model, in order to better understand the technology hand of the utility model
Section, below in conjunction with attached drawing, the utility model is described in further detail with specific embodiment.
Fig. 1 is the structural schematic diagram of the surface protective structure of the utility model wind electricity blade.
Specific embodiment
Referring to shown in attached drawing 1, the surface protective structure of the present embodiment wind electricity blade successively include from outside to inside top coat layer 1,
Prime coat 2, aramid fiber composite material layer 3 and putty layer 4, the putty layer 4 are applied directly to 5 outside of blade shell of blade, are formed
Wear-resisting property, weather resistance both stronger blade surface.
Wherein, which can be used chopped aramid fiber, long aramid fiber, aramid paper, aramid fiber woven cloth
Any one of.And the thickness of the thickness of the aramid fiber composite material layer 3 and priming paint 2 and finishing coat 1 and close.Specifically, the virtue
The thickness of synthetic fibre composite layer is less than 1mm.Putty, priming paint and finishing coat used in it, are all made of existing commercial product.
The blade surface safeguard structure can be used for blade whole body in the present embodiment, can also be served only for blade inlet edge position, or
It is blade inlet edge position of the blade maximum chord length at blade tip, according to practical blade use environment, considers that cost etc. is multifactor certainly
Fixed blade zone of protection.
The preparation method of above-mentioned wind electricity blade surface protective structure is first to coat in the blade shell outer surface of wind electricity blade
One layer of putty, is then laid with aramid fiber composite material on the outside of the putty, finally the spray-applied primer on the outside of the aramid fiber composite material again
And finishing coat, that is, complete the protected working of blade surface.
The utility model is by increasing by one layer of aramid fiber composite material in blade paint layer lower part, since aramid fiber composite material has
There is the features such as high thermal stability, anti-flammability, chemical stability, mechanical performance are high, light-weight, especially wearability is high, prolongs
The high feature of malleability, the blade surface safeguard structure of the increase aramid fiber composite material can greatly improve the resistance to rain in surface of blade
The performance of erosion, husky erosion, can also meet the requirement of blade surface color glossiness.
The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model
Limitation, those skilled in the art make a little simple modification, equivalent variations or modification using the technology contents of the disclosure above,
It falls within the protection scope of the present utility model.
