The principle of operation of the present invention will now be described as follows: the wind driven generator blade to be detected is relatively fixed between two abutting sliding plates, under the action of a compensation spring 84, the abutting sliding plates are tightly attached to the side of the wind driven generator blade, the distance between the two abutting sliding plates, namely the width of the current position of the blade to be detected, the PLC controller 10 controls the servo motor 33 to drive the rotating screw rod 32 to act, the reciprocating block 34 drives the image acquisition head 43 to transversely move through the threaded sleeving action of the rotating screw rod 32 and the reciprocating block 34, the image acquisition head 43 performs image shooting detection on the surface of the blade to be detected at the transverse position, when the image acquisition head 43 moves to the side of the blade, the magnetic attraction generated by the distance between the fixed magnetic plate 95 on the side wall of the feedback cylinder 52 and the adsorption magnetic plate 94 on the side wall of the vertical plate 82 can overcome the elasticity of the reset spring 93 to drive the trigger plate 92 to move in cooperation with the trigger rod 91, and then the trigger plate 92 acts on the trigger switch 96, the trigger switch 96 feeds back a signal to the PLC controller 10, the PLC controller 10 firstly controls the rotating motor 35 to drive the fixed shell 41 to rotate 180 degrees, so that the blade surface deformation follow-up monitoring feedback mechanism 5 and the cleaning processing mechanism 6 are reversed, and the servo motor 33 continues to act at the moment, so that the image acquisition head 43 continues to move to the side of the blade, the distance between the compensation feedback cylinder 52 and the image acquisition head 43 shields the blade surface, after the image acquisition head 43 also moves to the side, the PLC controller 10 firstly drives the sliding rail to longitudinally move for a certain distance, so that the image acquisition head 43 moves to the next transverse detection position of the blade surface to be detected, the PLC controller 10 then controls the servo motor 33 to reversely rotate, the servo motor 33 drives the rotating screw rod 32 to reversely rotate, and then drives the reciprocating block 34 to reversely move the image acquisition head 43, the method can automatically perform comprehensive defect detection operation on the surface of the blade based on the size of the blade of the wind driven generator, does not need programming control, and is simpler and more convenient to operate;
When the image acquisition head 43 moves to detect the surface of a blade, the abutting wheel 54 always abuts against the surface of the blade, along with the fluctuation of the surface shape of the blade, the abutting wheel 54 also moves up and down, when the surface shape of the blade rises, the abutting wheel 54 overcomes the elasticity of the push spring 55 and moves relatively upwards, and then the synchronous rod 53 and the synchronous plate 56 drive the elastic conductive tab 57 to move upwards, so that the elastic conductive tab 57 moves relatively upwards on the resistor rod 58, the access resistance value of the resistor rod 58 becomes larger, and because the elastic conductive tab 57 and the resistor rod 58 are connected in series on the power supply circuit of the thrust electromagnetic plate 47, the passing current of the thrust electromagnetic plate 47 becomes smaller, the magnetism of the thrust electromagnetic plate 47 is weakened, the image acquisition head 43 is driven to move relatively upwards under the action of the push spring 45, the distance between the image acquisition head 43 and the surface of the blade is regulated, otherwise when the surface of the blade has the downward shape change, the abutting wheel 54 moves relatively downwards under the action of the push spring 55, the access resistance value of the resistor rod 58 is smaller, the access resistance value of the resistor rod 58 is further, the image acquisition quality of the image is further increased, the image acquisition quality is further is improved, the image acquisition distance is further stable, the image acquisition distance is increased along with the increase of the surface detection distance of the surface of the blade is ensured, and the surface quality is stable, and the image acquisition is stable, the distance is stable, and the distance is stable along with the distance is increased, and the distance is measured along with the distance of the surface detection of the surface image is measured;
The PLC 10 synchronously starts the motor rotating assembly 66 to act when the image detection is carried out, the motor rotating assembly 66, namely a motor, is matched with a bevel gear driving mechanism, is not excessively repeated in the prior art, the motor rotating assembly 66 drives the rotary tube 62 to drive the hollow brush disc 63 to rotate, the surface of the blade to be detected is quickly cleaned, the PLC 10 controls the external air pump to be matched with the air suction tube 65 to form negative pressure suction force in the rotary tube 62, and then the hollow brush disc 63 and the suction head 64 are matched to quickly adsorb dust impurities cleaned, the detection position can be quickly cleaned before the image shooting detection is carried out on the surface of the blade, the problem that the dust impurities in the air environment are attached to the surface of the blade to further influence the image detection identification accuracy is solved, false detection operation is reduced, resources are saved, the detection efficiency and quality are improved, and because the brush hair on the lower surface of the hollow brush disc 63 is fixed with the surface of the blade in a fixed distance, the cleaning brush force is ensured, the problem that the cleaning effect is poor due to the fact that the cleaning distance is too small, and the problem that the surface of the blade is damaged due to the cleaning distance is extruded is avoided;
The PLC 10 also synchronously receives a result value of the image acquisition head 43 fed back to the external data processor after image detection and analysis, when detecting that the surface of the blade has defects, the PLC 10 controls the external liquid pump to cooperate with the liquid supply pipe 74 to supply erasable marking pigment into the annular buffer pipe 72, then the marking is carried out by dripping the dripper 73 onto the surface of the blade, and according to the defect degree problem, the PLC 10 controls the deflection motor 78 to drive the regulating gear 79 to rotate, the sealing ring 75 is driven by the meshing effect of the regulating gear 79 and the arc rack 77 to drive the arc baffle 76 to rotate, the larger the defect problem is, the larger the rotating angle of the arc baffle 76 is, the more the quantity of the marking liquid dripped on the surface of the blade is, the spraying marking can be automatically carried out after detecting that the surface of the blade has defects, the position of the defects can be conveniently and rapidly positioned by subsequent staff, the marking operation can be classified based on the defect degree, and the rapid judgment of the defect problem can be further facilitated by staff;
After one side of the blade is detected, the overturning motor 23 is controlled to drive the U-shaped mounting plate 1 to rotate 180 degrees, so that the whole detection mechanism rotates to the lower side of the blade to be detected, the power supply to the positioning electromagnetic plate 24 is cut off when the whole detection mechanism rotates, the positioning electromagnetic plate 24 is powered after overturning in place, the positioning electromagnetic plate 24 is electrified to generate the magnetic cooperation positioning permanent magnetic plate 25, the U-shaped mounting plate 1 can be firmly fixed, the two sides of the blade to be detected can be rapidly detected, and the detection efficiency is improved.
The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the invention are intended to be included within the scope of the invention.
