The invention discloses a fire airplane obstacle indicator for an overhead line. The fire airplane obstacle indicator comprises a hemispheric glass shell, a luminophor and a steel line clamp, wherein the luminophor is made from fluorescent cotton-circled polyester fasciated yarns and is arranged in a hollow cavity of the hemispheric glass shell; the upper end of the steel line clamp is clamped on a conductive wire of the overhead transmission line, and the lower end of the steel line clamp is fixed on the hemispheric glass shell. The fire airplane obstacle indicator disclosed by the invention has the following advantages: the fire airplane obstacle indicator can be hung on the overhead line, and can be used for indicating the position of the overhead line and playing a warning role; the fire airplane obstacle indicator does not use a power supply, is applicable to remote places such as forests and mountainous areas, has the characteristics of being easy to observe and arrange, being dampproof and the like, and has high environmental suitability; the fire airplane obstacle indicator is low in cost, and convenient to install and maintain; the fire airplane obstacle indicator is capable of forming reflection by virtue of firelight and sunlight, thus being beneficial to identifying the transmission line by a pilot and improving identification degree.
Description
technical field [0001] The invention belongs to the technical field of electric power facilities, in particular to an obstacle indicator for fire-fighting aircraft of overhead lines. Background technique [0002] When using fire-fighting aircraft to perform forest fire-fighting tasks, sometimes the overhead power transmission line is in the vicinity of the temporary fire-fighting rescue route and faces the danger of contact. Especially when a forest fire breaks out, the thick smoke will block the pilot's sight, making it more difficult for the pilot to observe with the naked eye. loss of life. In addition, even if a radar system is used for detection, it will be difficult to identify due to the small cross-section of the conductors on the transmission line, so there is a greater risk of work. Therefore, in order to safely complete forest fire rescue tasks, it is necessary to improve the identification of firefighting aircraft on power transmission lines. [0003] Although...
