The solar panel 26 then converts solar energy into electrical energy, which is stored in the battery 22. Simultaneously, the operator activates the second motor 24. The output of the second motor 24 drives the rotating block 25 to rotate, thus rotating the solar panel 26. The angle of the solar panel 26 is adjusted according to the sun's direction. In inclement weather, the operator activates the electric telescopic rod 19. The telescopic end of the electric telescopic rod 19 lowers the moving plate 20, allowing the solar panel 26 to enter the storage frame 5. Then, the operator activates the first motor 8. The output of the first motor 8 drives the threaded rod 9 to rotate, causing the lifting plate 11 to descend along the limiting rod 10. This allows the fixed frame 3 and the display screen body 4 to enter the storage seat 1. When the bottom of the storage frame 5 is in contact with the top of the storage seat 1, the sealing ring 2 enters the sealing groove 18, thus completing the seal and improving protection, preventing damage to the display screen body 4. At the same time, the inclined surface of the support plate 6 contacts the outer wall of the U-shaped plate 14, the support plate 6 pushes the U-shaped plate 14 to move, the spring 13 is compressed until the U-shaped plate 14 blocks the top opening of the storage frame 5, thus protecting the solar panel 26.
