[0002] As my country's infrastructure enters a period of large-scale maintenance, the safety risks of routine maintenance operations on highways, bridges, tunnels, and other facilities are becoming increasingly prominent. According to statistics on maintenance operation accidents, traffic accidents account for as much as 42% of all accidents in maintenance work areas. Traditional maintenance operations face unique challenges: (1) High degree of openness in the working environment: The operation needs to be carried out next to passing vehicles. (2) Special operating time period: high proportion of low visibility conditions such as night and rain / fog. (3) Frequent equipment movement: The warning device needs to be dynamically adjusted according to the work surface. (4) The age structure of the staff is relatively old: their acceptance and adaptability to new technologies are relatively low.

[0003] Traditional warning devices include manual traffic control, traffic cones, flashing warning lights, audible and visual alarms, and physical barriers. Manual traffic control is mainly used for traffic guidance, but due to the chaotic environment of maintenance work areas, it poses significant personal safety hazards. Traffic cones are simple in structure, lightweight, and portable, and are widely used, but they are prone to tipping over, requiring frequent manual adjustments, and untimely adjustments further increase the difficulty of passage. Flashing warning lights and audible and visual alarms cannot effectively demarcate work area boundaries and are greatly affected by the surrounding environment (such as nighttime or inclement weather, environmental noise, etc.), limiting their application. Physical barriers (such as steel pipe fastener guardrails) offer good stability and effective work area boundary demarcation, but they are bulky, inconvenient to carry and operate, time-consuming to install, and obstruct the passage of construction machinery.

[0004] Therefore, designing a portable safety warning device for maintenance management that is easy to operate and disassemble, and that ensures good stability and adaptability is an urgent technical problem to be solved. Utility Model Content
