Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is further described.With
Lower embodiment is only used for clearly illustrating the technical solution of the utility model, and can not limit this with this
The protection domain of utility model.
As it is shown in figure 1, this utility model is a kind of blade being easily repaired, including housing 1, connect abdomen
Plate 2 and protective layer 3；Housing 1 is internal has cavity 4, connects web 2 and is positioned at cavity 4 inside and housing
1 interior surface connects；Protective layer 3 covers the outer surface at housing 1, has between protective layer 3 and housing 1
Binding agent, for being fixed on housing 1 by protective layer 3.
Preferably, constitute, at adjacent two-layer glass if protective layer 3 is covered successively by dried layer glass fabric 31
Between glass fiber cloth 31, there is binding agent, to connect adjacent layer glass fiber cloth 31.
Preferably, protective layer 3 and housing 1 pass through resin bonding；Outer surface at protective layer 3 scribbles anti-
Rotten paint, for preventing protective layer 3 from being corroded by extraneous moisture and wind-force with housing 1.
Preferably, glass fabric 31 is plain weave glass cloth 313 or twill glass cloth 311.
