DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1 - 3 , the present invention provides a technical solution: an LED display screen for exhibitions, as shown in Figure 1 , Figure 2 and Figure 3 . At both ends of the bottom of the mounting plate 1, columns 2 are fixed, and at the bottom of the columns 2, a bottom plate 3 is fixed. A stabilizing mechanism 4 is arranged on the bottom plate 3. At the top of the mounting plate 1, a fixing plate 5 is fixed. On the side of the fixing plate 5, a display screen 6 is installed. At the top of the fixing plate 5, a rain shield 7 is fixed. At the bottom of the rain shield 7, a bellows cover 8 is installed, and at the bottom of the bellows cover 8, a rectangular frame 9 is fixed;

[0029] On the rain shield 7, a driving component 10 is arranged, and the driving component 10 is used to drive the rectangular frame 9 to move vertically.

[0030] As shown in Figure 1 , the stabilizing mechanism 4 includes a screw rod 401, which is installed at the midpoint of the top of the bottom plate 3. A movable plate 402 is threadedly connected to the screw rod 401. At the bottom of the movable plate 402, a plug rod 403 is fixed, and the plug rod 403 penetrates through the bottom plate 3.

[0031] There are several groups of the plug rods 403.

[0032] As shown in Figure 1 and Figure 2 , the driving component 10 includes a first motor 1001, which is fixed at one end of the bottom of the rain shield 7. At both ends of the bottom of the rain shield 7, a first lead screw 1002 and a guide rod are respectively installed. The first lead screw 1002 is connected to the output end of the first motor 1001, and the first lead screw 1002 and the guide rod respectively penetrate through both ends of the rectangular frame 9.

[0033] As shown in Figure 1 and Figure 3 , a cleaning plate 11 is also arranged on the side of the fixing plate 5. An empty groove 12 is formed on the mounting plate 1, and a transverse movement component 13 is also arranged on the mounting plate 1.

[0034] As shown in Figure 1 and Figure 3As shown in the figure, the transverse movement component 13 includes a second motor 1301. The second motor 1301 is fixed to the side of the mounting plate 1, and the output end of the second motor 1301 is connected to a second lead screw 1302. The second lead screw 1302 is installed in the empty slot 12, and a movable block 1303 is slidably connected in the empty slot 12. The second lead screw 1302 passes through the movable block 1303 and is threadedly connected thereto, and the movable block 1303 is connected to the cleaning plate 11.

[0035] Working principle: During installation, the rotatable screw 401 drives the movable plate 402 and the insertion rod 403 to descend. A plurality of groups of insertion rods 403 can be evenly distributed and inserted into the ground soil and sand to improve the stability of the bottom plate 3 and the display screen 6. When there is dirt on the surface of the display screen 6 during use, the second motor 1301 can be turned on to drive the second lead screw 1302 to rotate, so that the second lead screw 1302 drives the movable block 1303 to move horizontally in the empty slot 12, thereby driving the cleaning plate 11 to move horizontally to clean the surface of the display screen 6. When the display screen 6 is not in use, the first motor 1001 can be turned on to drive the first lead screw 1002 to rotate, so that the first lead screw 1002 drives the rectangular frame 9 to descend to stretch the bellows 8. The stretched bellows 8 will surround the fixing plate 5 and the display screen 6 together to protect the display screen 6 from being damaged by weather such as wind, rain, flying ash, and exposure to high temperatures.
