Underground transmission line connection device capable of connecting multiple underground transmission lines

摘要

The present invention relates to an underground transmission line connection device capable of connecting a plurality of underground transmission lines, and is installed in the form of a cantilever at regular intervals on the wall surface (W) of a power tool to support the underground transmission line (L) installed along the power tool, and is required. Support arm unit 100 that allows additional installation of an underground transmission line (L) through an extension function according to: The support arm unit 100 is installed in the form of a cantilever on the wall surface (W) of the power outlet to be disposed between the support arm units 100 A transmission line inspection assembly 200 capable of separating or seating L) from the support arm unit 100, extinguishing fire around the surrounding by discharging extinguishing agents, and temporarily mounting tools necessary for work: first driving means The operation switch 300 outputting an operation signal so that the 235 and the second driving means 265 can be operated: a fire detection sensor installed in the transmission line inspection assembly 200 to detect a fire and output a detection signal ( 400): Receives an operation signal from the operation switch 300 to individually control the operation of the first driving means 235 and the second driving means 265, respectively, and receiving a fire detection signal from the fire detection sensor 400 And a control unit 500 for operating and controlling the first driving means 235 so that the push button 273 can be pressed by the ceiling surface C of the power tool. According to this embodiment, it is possible to easily connect a plurality of underground transmission lines through the expansion function, and to sufficiently separate the sagging underground transmission lines from the support arm unit without excessive lifting during facility inspection, so that even if the ceiling of the power outlet is low, it can be sufficiently used. It is possible to reinforce the convenience of use, and in the event of a fire, the surroundings can be quickly extinguished using extinguishing agents, minimizing the damage caused by the fire, and the convenience of work can be improved by installing the necessary tools. There are features.
