Description

Technical Field

[0001] This utility model relates to the field of warning device technology, and more specifically, to a mobile warning device for transportation. Background Technology

[0002] my country's road construction has passed a peak period. As time goes by, cracks and potholes appear on the previously built road surfaces, which requires the dispatch of special personnel for road monitoring and repair. Major and medium road repairs have also become an important task for road maintenance workers. Currently, when repairing roads and bridges, warning signs need to be set up outside the repair site to warn passing vehicles and pedestrians to avoid danger.

[0003] In the existing technology, most warning devices are located in environments with high levels of dust. As vehicles travel back and forth, a large amount of dust accumulates on the surface of the warning display screen. Especially when maintenance work is carried out at night, if the screen is not cleaned, it may affect its warning effect. Utility Model Content
