[0002] Safety management of construction areas is crucial during road and bridge construction, especially in potentially hazardous areas such as unstable slopes, high-altitude work areas, and heavy machinery operations. To ensure the safety of construction workers, traditional methods include warning signs, cordoning, and verbal reminders. However, these methods are often ineffective in complex and changing construction environments, particularly in low light conditions, obstructed vision, or when workers are distracted.
[0003] To enhance safety warnings in construction areas, temporary warning devices using electronic display technology have emerged in recent years. These devices, through their built-in display screens, dynamically display safety warning messages, such as "Beware" and "Wear a Safety Helmet." Their striking visual effects and flexible information display capabilities significantly enhance the effectiveness of safety warnings. However, the harsh environment of road and bridge construction is often characterized by falling rocks and flying dust. These environmental factors can easily lead to dust accumulation on the warning device's display screen, affecting the display quality and even blurring the warning message, making it difficult for construction workers to perceive, thereby weakening its intended safety warning function. Therefore, to address these technical issues, a temporary warning device for road and bridge construction is proposed. Utility Model Content
