[0038] The implementation principle of an outdoor information display screen of this embodiment is as follows:

[0039] When the display screen body 1 needs to be cleaned, the operator first needs to start the driving motor 7, and the driving motor 7 drives the driving gear 11 connected to the output shaft to rotate, and the driving gear 11 is meshed with a positioning rack 10, and the positioning rack 10 is fixed on the display screen body 1. The driving gear 11 can move on the positioning rack 10 at this time, driving the outer cover 5 to move vertically downward, and the limiting plate 8 on the outer cover 5 slides on the limiting guide rail 6, which achieves the purpose of limiting.

[0040] During the rotation of the driving gear 11, the turntable 12 coaxially mounted with the driving gear 11 rotates, and a cam groove 18 is opened on the turntable 12. The position of the cam groove 18 changes, thereby driving the positioning slider 19 slidably mounted on the cam groove 18 to move left and right. The positioning slider 19 can drive the push rod 20 to move left and right synchronously. The push rod 20 pushes the sealing plug 21 to move into the water tank 9. The sealing plug 21 is slidably connected along the guide rod 22. When the sealing plug 21 is completely inserted into the conical water outlet of the water tank 9, the water outlet is open at this time, so that water can be discharged from the water tank 9. The water can fall onto the water guide plate 23, and then fall onto the display screen body 1 through the water guide plate 23, so as to moisten the surface of the display screen body 1 and wash away small dust.
