Device for preventing external damage of power transmission line cable

Abstract

The invention discloses a device for preventing external damage of a power transmission line cable, which can timely and reliably discover abnormity in a cable erection direction, can carry out evidence collection, warning and regular inspection along the line on external damage, reduces the probability of unintentional damage of external equipment, and increases the warning effect on artificial damage. According to the device, two adjacent telegraph poles are provided with monitoring assemblies used for monitoring the approaching of foreign matters to cables, the cables on the two adjacent telegraph poles are connected with warning assemblies in a hanging manner, and the cables on the two adjacent telegraph poles are also provided with detection assemblies used for detecting whether the cables are damaged; each monitoring assembly comprises a laser monitoring assembly and a visual monitoring assembly; and each laser monitoring assembly comprises a lower box body, one side face of the lower box body is provided with a laser receiving assembly used for receiving laser signals of the laser monitoring assembly on the previous telegraph pole, and the side face of the lower box body is provided with a laser emitting assembly used for emitting laser to the next telegraph pole in the cable erecting direction.

Description

Technical field [0001] The present invention relates to an apparatus for preventing external transmission line cable break, particularly for cable transmission line stop preventing outside damage. Background technique [0002] In recent years, with the rapid economic and social development, expanding the scale of construction in the city, road, rail, pipeline networks improve and perfect, all kinds of large-scale power facility protection areas are widely used in construction machinery and equipment, but because of their geographic power lines particularity location and environmental conditions, location of the tower installation, wide area, long distance power transmission equipment in the field of long-term exposure to the state, the threat of severe weather changes in equipment safe and reliable operation at the same time, all kinds of illegal cases also violation wherein associated, such as power cables and equipment theft device, the high pressure exceeds a safe distance is ...

AI Technical Summary

Problems solved by technology

[0005] (1) The traditional prevention of cable damage by external forces relies on manual regular inspections. Since manual inspections are passive protection, it is impossible to grasp the construction conditions near the cable passage in real time; workload is increasing

[0006] (2) Some intelligent anti-breakage devices are currently only equipped with monitoring cameras. The long-term use of monitoring cameras has caused a high pressure on data storage and transmission. Often when it is really necessary to call the scene to affect the capture of evidence, the camera cannot reliably obtain evidence;

[0007] (3) The current camera monitoring and anti-breakage method cooperates with the buzzer or warning light to alarm, the protective effect is very small, and regular cable breakage inspections cannot be carried out, and the cable damage cannot be found in time, and there are still damages that expand and cause large-scale power outages Passive situation of emergency repair
