[0029] Working principle:

[0030] When the enhanced display imaging device is in use, the protective shell 1 is installed at a suitable position on the construction site by screwing and cooperating with the mounting block 2. When the display screen 13 needs to display an image, the dual-axis motor 3 is started to drive the drive shaft 4 and the driving bevel gear 5 to rotate. The driving bevel gear 5 drives the lifting screw rod 8 to rotate through the driven bevel gear 9, thereby driving the support plate 10 to move upward, pushing the outer shell 12 and the display screen 13 out of the outer shell 12, and displaying an image through the display screen 13. Through the setting of the light-shielding cover 14, when the display screen 13 is used outdoors, the display screen 13 is shielded to prevent strong light from directly shining on the display screen 13, thereby enhancing the imaging effect of the display screen 13 and ensuring the imaging quality.

[0031] During the display process, when there is dust on the display screen 13, the stepping motor 15 and the hair dryer 20 are started. The hair dryer 20 blows air onto the display screen 13 through the ventilation plate 18 to blow away the dust on the display screen 13. At the same time, the stepping motor 15 works to drive the driving gear 16 to rotate. The driving gear 16 drives the rotating column and the ventilation plate 18 to rotate through the driven gear 19 to blow air at different positions of the display screen 13 and blow away the dust at different positions on the display screen 13, avoiding the influence of dust on the display effect of the display screen 13 and further enhancing the display imaging.

[0032] When the use of the display screen 13 is completed, the dual-axis motor 3 rotates in the reverse direction to drive the support plate 10 to descend, so that the outer shell 12 and the display screen 13 descend into the protective shell 1. The protective plate 21 fits on the surface of the protective shell 1 to seal the protective shell 1 and effectively protect the display screen 13, extending the service life of the display screen 13.
