Abstract

The present invention relates to an underground power transmission line connection device allowing easier and more convenient connections, the connection device comprising a support mechanism (10), a connector mechanism (80), first and second clamp mechanisms (90, 90'), an inclined roller (20), a vertical roller (30), a horizontal roller (40), a wire-pushing mechanism (50), a movement sensor (60), and a harmful animal-repelling device (70). The connection device allows convenient connection of underground power transmission lines (L) and safe laying-out of same, prevents electrical shorts from occurring by blocking access by harmful animals, and allows an underground power transmission line (L) inserted and pulled between the inclined roller (20), vertical roller (30), and horizontal roller (40) to be placed on the upper surface of a wire support part (12) conveniently and without difficulty.

Abstract

The present invention relates to an underground power transmission line connection device having a fire-fighting function, the connection device comprising a support mechanism (10), a fire sensor (100), a fire-fighting mechanism, a connector mechanism (80), first and second clamp mechanisms (90, 90'), an inclined roller (20), a vertical roller (30), a horizontal roller (40), a wire-pushing mechanism (50), a movement sensor (60), and a harmful animal-repelling device (70). The connection device allows rapid fire-fighting, convenient connection of underground power transmission lines (L) and safe laying-out of same, prevents electrical shorts from occurring by blocking access by harmful animals, and allows an underground power transmission line (L) inserted and pulled between the inclined roller (20), vertical roller (30), and horizontal roller (40) to be placed on the upper surface of a wire support part (12) conveniently and without difficulty.
