Abstract
The utility model discloses a corrosion-resistance fan blade, which comprises a glass fiber layer at the inner layer and an epoxy resin layer at the outer layer, wherein on the wind cutting surface of the fan blade, a PE plastic layer is also arranged outside the epoxy resin layer, and the tie linear structure and the thickness of the fan blade after the additional arrangement of the PE plastic layer on the wind cutting surface of the fan blade are not changed. Generally, compared with the existing fan blade, the utility model has the reduced epoxy resin layer or/and the reduced thickness of the glass fiber layer, a layer of PE plastic layer can be added, the PE plastic layer has the elasticity and can resist the attack of wind, sand and the like, the damage on the fan blade by the wind and the sand can be reduced, the PE plastic layer also has stronger corrosion-resistance capability, and the corrosion-resistance capability in the humid environment can also be improved. Thereby, the fan blade has stronger capability of resisting the wind and sand attack, resisting the humid stain and the like, and the service life is long.
Description
Technical field
The utility model relates to a kind of blade of wind-driven generator, is specifically related to a kind of erosion-resistant fan blade.
Background technique
The rotation of facining the wind of blade of wind-driven generator (fan blade) is the power source of wind-driven generator.The fan blade of present length above 1.5 meters generally is made of the glass fibre layer and the outer field epoxy resin layer of internal layer, and the fan blade after the processing unavoidably exists pore and hard fragility like this, and the wind cutting face is subjected to the influence of dust storm, humidity easier to be crisp firmly.Use fan blade in the environment on or seashore heavier at dust storm, the wind cutting face of fan blade is subject to dust storm and invades and hit or moist dirty erosion and damaging, thereby reduces the working life of fan blade, reduces the efficient of wind-driven generator.
Summary of the invention
It is stronger that technical problem to be solved in the utility model provides the abilities such as dirt erosion that invading of a kind of anti-blown sand hit, moisture resistance is wet, the erosion-resistant fan blade that working life is higher.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of erosion-resistant fan blade, the glass fibre layer and the outer field epoxy resin layer that comprise internal layer, it is characterized in that the wind cutting face at described fan blade, described epoxy resin layer also is provided with the PE plastic layer outward.
Compared with prior art, the utility model has the advantages that a kind of erosion-resistant fan blade, the glass fibre layer and the outer field epoxy resin layer that comprise internal layer, wind cutting face at fan blade, epoxy resin layer also is provided with the PE plastic layer outward, after the wind cutting face of fan blade is added with the PE plastic layer in addition, its tie lines structure and thickness do not change, generally just compared with former fan blade, epoxy resin layer diminishes or all diminishes with the glass fibre layer thickness, just can increase one deck PE plastic layer, PE plastic layer tool elasticity, can resist invading of dust storm etc. hits, reduce the damage of dust storm to fan blade, the PE plastic layer also has stronger antiseptic power, also can improve the anti-corrosion capacity of wet environment, therefore invading of this fan blade anti-blown sand hit, the abilities such as dirt erosion that moisture resistance wets are stronger, and working life is higher.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Embodiment
Erosion-resistant fan blade as shown in Figure 1 and Figure 2, the glass fibre layer 1 and the outer field epoxy resin layer 2 that comprise internal layer, wind cutting face 4 at fan blade, the less thick of epoxy resin layer 2, tapered thickness just can be provided with one deck PE plastic layer 3, make the linearity and the thickness of fan blade constant, just be divided into glass fibre layer 1, epoxy resin layer 2 and PE plastic layer 3 three-deckers like this on the wind cutting face of fan blade from inside to outside, the PE plastic layer 3 of outside has elasticity and antiseptic power, has improved the abilities such as dirt erosion that invading of fan blade anti-blown sand hit, moisture resistance is wet.
Also can allow the thickness of epoxy resin layer and glass fibre layer diminish simultaneously in the foregoing description in the wind cutting face 4, to increase one deck PE plastic layer.
Claims (1)
1. erosion-resistant fan blade comprises the glass fibre layer and the outer field epoxy resin layer of internal layer it is characterized in that the wind cutting face at described fan blade that described epoxy resin layer also is provided with the PE plastic layer outward.
