A human lifting drive assembly is provided at the lower end of the other side of the first square tube 2. The human lifting drive assembly is connected to the second square tube 3 via a transmission assembly arranged in the first square tube 2. Wheels 4 are provided at the four bottom corners of the bottom plate 1.

[0024] The transmission assembly includes a first bevel gear 9, a second bevel gear 10, a supporting threaded rod 11 and a driving bevel gear 12; the central axis of the second bevel gear 10 is movably connected to the middle of the lower end of the first square tube 2, the center of the second bevel gear 10 is fixedly connected to the lower end of the supporting threaded rod 11, the upper end of the supporting threaded rod 11 is threadedly connected to the second square tube 3, and the top of the second square tube 3 is fixedly connected to the LED screen 5;

[0025] The output shaft of the motor 7 is fixedly sleeved at the center of the first bevel gear 9 , the first bevel gear 9 is meshed with the second bevel gear 10 , and the second bevel gear 10 is meshed with the manual lifting drive assembly arranged at the lower end of the other side of the first square tube 2 .

[0026] The connecting assembly includes a hollow cylinder 15, an upper support rod 16 and an upper support plate 19; the hollow cylinder 15 is arranged on the top of the LED screen 5, and a horizontally arranged limit block 17 is provided on the upper part of the cavity of the hollow cylinder 15, and the bottom surface of the limit block 17 is connected to the top of the LED screen 5 via a spring 18;

[0027] An upper support rod 16 is provided on the top surface of the limit block 17, and the top end of the upper support rod 16 passes through the top surface of the hollow cylinder 15 and is connected to an upper support plate 19 located above the hollow cylinder 15. A solar panel assembly 6 is provided on the top of the upper support plate 19, and the angle of the solar panel assembly 6 is adjusted by directly rotating the upper support plate 19. After the upper support plate 19 is rotated, the position of the support plate 19 can be fixed by the spring 18 fixed between the limit block 17 and the LED screen 5, and will not rotate at will.

[0030] When using this device, first push the device to move to the position where a safety warning is required, then the solar panel assembly 6 will provide energy for the battery 2, and the battery will be electrically connected to the motor 7 and the LED screen 5 respectively, so that the battery can power the motor 7 and the LED screen 5.

[0031] Then, the height of the LED screen 5 is adjusted according to the actual situation. The first bevel gear 9 is driven to rotate by the motor 7, which drives the second bevel gear 10 to rotate and then drives the supporting threaded rod 11 to rotate. The supporting threaded rod 11 rotates to drive the second square tube 3 to move upward or downward, thereby completing the lifting and lowering adjustment of the LED screen 5.

[0032] The motor 7 is connected to the battery. When the battery has power, the motor 7 drives the above components to adjust the height of the LED screen 5. When the battery is out of power, such as continuous rainy weather causing the solar panel assembly 6 to supply insufficient power to the battery, a wrench is used to rotate the hexagonal head bolt 14, which in turn drives the drive shaft 13 to rotate and drives the drive bevel gear 12 to rotate, and the drive bevel gear 12 drives the support threaded rod 11 to rotate, and finally drives the second square tube 3 to move up and down to adjust the position of the LED screen 5, that is, the height of the LED screen 5 can be adjusted without the need for electricity.

[0033] The LED screen will provide drivers or pedestrians with road geometry information, road conditions information, road section traffic information and social public service information, so as to reduce traffic accidents and improve the traffic capacity of the road network.
