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.
Further, twill glass cloth 311 is 45 ° of twill glass cloth 311;Plain weave glass cloth 313 is 90 °
Plain weave glass cloth 313 or 0 ° of plain weave glass cloth 313.
Preferably, housing 1 is made up of carbon fiber or fiberglass.
By following maintenance program, the above-mentioned blade being easily repaired can be repaired:
Maintenance program S1:
As shown in Figures 2 and 3, the maintenance program damaged after 311 for twill glass cloth is as follows:
S11: check degree of impairment, finds the damage location of protective layer 3, and calculates damaged area, meanwhile,
Face is processed in the outer surface delimitation of protective layer 3 according to damaged area;
S12: along the thickness direction grinding process face of protective layer 3, until being polishing to intact twill glass cloth 311
Till, making polishing region form each sidewall is step-like groove 32, the top end opening of groove 32 and the face of process
Unanimously, and record number of plies X of twill glass cloth 311 of polishing;Wherein, the face of process is square, processes
A wherein limit in face is parallel to the axial of blade, the riser side of groove 32 sidewall towards the axis of groove 32,
The tread side width of groove 32 sidewall is 50 millimeters, and X is natural number;
S13: each sidewall of groove 32 is polished into smooth inclined-plane by stairstepping;
S14: cleaning groove 32 also prepares X+1 layer new twill glass cloth 312, by new for ground floor twill glass
Cloth 312 spreads on bottom and each side of groove 32, is connected with twill glass cloth 311;Again by remaining
X layer new twill glass cloth 312 is sequentially coated on the upper surface of ground floor new twill glass cloth 312;Wherein,
All infiltrated by resin between every two-layer new twill glass cloth 312 and be compacted.
S15: twill glass cloth 312 new to X+1 layer heats, and makes resin be sufficiently hardened;
S16: to process face and be positioned at outermost new twill glass cloth 312 brushing corrosion resistant coating.
Maintenance program S2:
As shown in Figure 4 and Figure 5, the method for maintaining after damaging for plain weave glass cloth 313 is as follows:
S21: check degree of impairment, finds the damage location of protective layer 3, and calculates damaged area, meanwhile,
Face is processed in the outer surface delimitation of protective layer 3 according to damaged area;
S22: along the thickness direction grinding process face of protective layer 3, until being polishing to intact plain weave glass cloth 313
Till, making polishing region form each sidewall is step-like groove 32, the top end opening of groove 32 and the face of process
Unanimously, and record number of plies X of plain weave glass cloth 313 of polishing;Wherein, process face is rectangle, processes face
Long limit be parallel to the axial of blade;The opening of groove 32 is rectangle, the riser side of groove 32 sidewall towards
The axis of groove 32, the tread side width of the long side wall of groove 32 opening is 20 millimeters, groove 32
The tread side width of minor face sidewall is 100 millimeters, and X is natural number;
S23: each sidewall of groove 32 is polished into smooth inclined-plane by stairstepping;
S24: cleaning groove 32 also prepares X+1 layer new plain weave glass cloth 314, by new for ground floor plain weave glass
Cloth 314 spreads on bottom and each side of groove 32, is connected with plain weave glass cloth 313, then by remaining
X layer new plain weave glass cloth 314 is sequentially coated on the upper surface of ground floor new plain weave glass cloth 314;Wherein,
All infiltrated by resin between every two-layer new plain weave glass cloth 314 and be compacted.
S25: plain weave glass cloth 314 new to X+1 layer heats, and makes resin be sufficiently hardened;
S26: to process face and be positioned at outermost new plain weave glass cloth 314 brushing corrosion resistant coating.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model,
All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all
Within protection domain of the present utility model should be included in.
