With the rapid development of national economy and the continuous expansion of urban scale, transmission lines are more and more dense, and the operation environment is increasingly complex; many transmission lines span highways, railways, bridges, rivers, lakes, and across mountains, building groups, etc. In recent years, there are many cases where an electric power line is damaged by external force such as offline construction and ultra-high vehicles, for example: when a construction site is under or near the power transmission line, and a construction vehicle or machinery works under the power transmission line or passes under the power transmission line, a high-raised part of the construction vehicle or machinery sometimes enters a safety limit distance of the power transmission line to cause the power transmission line to be discharged, and even the construction vehicle or machinery is hung on the power transmission line to cause the grounding, tripping and even disconnection of the power transmission line. The power supply reliability of a power supply company is seriously influenced, and meanwhile, personal casualty accidents easily occur.

When the existing power line is constructed or ultrahigh vehicles and the like are operated on line, no effective early warning means exists, and particularly, when the existing power line is constructed at night, the safety distance is difficult to identify, so that external damage accidents are easy to happen. Or the alarm system is too complex, increasing the laying cost.

Therefore, it is an urgent technical problem to be solved by those skilled in the art to provide an alarm device for preventing an external damage of an overhead power line, which is applicable to night and has a simple structure.
