A sliding groove is provided at the bottom of the first sliding groove 31. A protrusion is provided at the bottom of the first sliding column 29 corresponding to the sliding groove.

[0026] Furthermore, a mounting seat is rotatably provided at the bottom of the second movable plate 17, which is fixed to the ultraviolet emitter 19 through the mounting seat, and other detection modules and illumination components can be installed on the mounting seat.

[0027] Working principle: When the device is used, the staff first installs the turbine blades and the rotating seat 21, and completely fixes the turbine blades through the rotating seat 21 to prevent the turbine blades from shaking. First, the flatness, glossiness, color, and concave-convexity of the product surface are observed by naked eyes to determine whether the surface quality meets the requirements. Then, the lighting component on the second movable plate 17 is adjusted to provide sufficient lighting for the turbine blades. Under appropriate lighting conditions and visual angles, the inspector does not rely on any inspection tools to perform manual visual inspection of all the welds to be inspected. The driving motor 36 set at the bottom drives the rotating seat 21 to rotate, thereby facilitating observation at various angles and conducting preliminary surface inspection. When it is necessary to detect tiny cracks and defects on the surface of turbine blades, a cleaning agent or solution is filled in the cleaning water tank 8, which is pumped by the water pump 16, and the turbine blades are sprayed and cleaned by the nozzle 18. At the same time, the turbine blades are driven to rotate by the driving motor 36 to facilitate cleaning of all surfaces of the turbine blades. The water is drained through the water tank 20 provided on the fixed plate 7. After cleaning, the fluorescent penetrant is prepared for application. The first movable plate 12 is driven downward by the first electric telescopic machine 11, and the first fixed plate 10 provided on both sides of the second vertical plate 5 guides the first movable plate 12 so that the first movable plate 12 moves vertically downward. The movable column 22 is moved to the side close to the opening 6 by contracting the second electric telescopic machine 13, and the fluorescent penetrant is manually added to the application plate 28 by the staff, and then the first movable plate 12 is driven upward by the first electric telescopic machine 11, and the second electric telescopic machine is used to The machine 13 drives the first connecting rod 14 to move, thereby adjusting the position of the movable column 22. When the movable column 22 moves to the turbine blade, the driving motor 36 drives the rotating seat 21 to rotate, thereby driving the turbine blade to rotate slowly, so that the driving motor 36 stops working after the turbine blade contacts the smear plate 28, and the force applied to the smear plate 28 by the turbine blade drives the smear plate 28 to deflect. The deflection of the smear plate 28 causes the first sliding column 29 to slide in the first sliding groove 31 provided on the second fixed plate 30, and the first rotating column 25 follows the deflection, so as to facilitate the smearing treatment of the turbine blade with an irregular plane. The rotating motor 143 drives the rotating rod 142 to rotate, thereby adjusting the angle of the smear plate 28 in the horizontal direction. At the same time, the upper and lower positions of the smear plate 28 are adjusted by the first electric telescopic machine 11, and the horizontal position of the smear plate 28 is adjusted by the second electric telescopic machine 13, thereby applying the fluorescent penetrant to the turbine blade. After the application is completed, according to the requirements of the fluorescent penetrant, wait for a period of time to allow the fluorescent penetrant to fully penetrate into the cracks and defects of the blades, clean the turbine blades through the nozzle 18 set on the top to make their surface dust-free, wait for the blades to dry, and then irradiate the surface through the ultraviolet emitter 19 to find out whether there is fluorescence. The position and intensity of the fluorescence will show the cracks and defects of the blades.
