[0026] Working principle: when there is glue in the transparent glue-repairing tube 100, and when the glue-repairing position is deep, the extension tube can be connected through the internal threaded sleeve 15, so as to facilitate extending to a deeper depth for glue-repairing. When glue-repairing, the lighting lamp 14 and the camera 13 are turned on, and the glue-repairing position is illuminated by the lighting lamp 14, and the camera 13 is used for monitoring at the same time, and the monitored picture is transmitted to the display screen 1, and the glue-repairing situation can be intuitively seen through the display screen 1, so that the personnel can conveniently perform the glue-repairing operation;

[0027] When repairing glue, the vent valve 4 and the first solenoid valve 16 can be opened, and the T-shaped push rod 102 can be pressed downward. The T-shaped push rod 102 moves downward and drives the piston 101 to move downward. The piston 101 stretches the telescopic hose 8. The piston 101 moves downward and squeezes the glue inside the glue repair transparent tube 100. Under the squeezing force, the glue is discharged through the first solenoid valve 16, the internal threaded sleeve 15 and the extension tube in sequence to repair the wind turbine blade.

Under the suction force, the glue inside the external glue storage box is sucked through the one-way valve 6, the second solenoid valve 7, the telescopic hose 8, the L-shaped tube 10, the first hose 9 and the suction pipe head 11 in turn. Under the suction force, the glue is kept in a state of being sucked out. The liquid is discharged to the bottom of the piston 101 through the suction pipe head 11, the first hose 9, the L-shaped tube 10, the telescopic hose 8, the second solenoid valve 7 and the one-way valve 6, thereby achieving the purpose of directly replenishing glue. After the glue replenishment is completed, the second solenoid valve 7 can be closed, the suction pipe head 11 can be removed from the glue storage box, and the suction pipe head 11 can be fixed in the U-shaped fixed block 12 again through the first magnet and the second magnet, thereby completing the glue replenishment operation, and the glue replenishment operation can be continued.
