The present invention relates to a device for supporting an underground distribution line. The device for supporting an underground distribution line includes a fixing unit (20), a lift (30), a buoyancy body (40) and a connector unit (50) buried in the ground and accommodated therein, and a protection box (10) that protects the distribution line (L) that are electrically connected from an external force, wherein the fixing unit (20) is fixed to the inner bottom surface of the protection box 10 buried in the ground through a fixing means (e.g., an anchor bolt), the lift (30) is installed to be lifted on a guide rod (21) of the fixing unit (20) to support the connector unit (50), and stably supports and protects the cable (C) drawn into the inside, the buoyancy body (40) is attached to the lower surface of a base (31) of the lift (30) and floats on water, and the connector unit (50) is detachably installed on the lift (30) and electrically interconnects and fixes the power distribution line (L) drawn in through the protection box (10). According to this embodiment, when seepage water penetrates into the inside of the protection box, the buoyancy body naturally elevates, thereby minimizing contact with the penetrating water as the connector units installed on the lift and electrically interconnecting the distribution lines are raised and lowered. Accordingly, it is possible to safely protect the connection state of the distribution line from accidents such as electric short due to seepage water.

    본 발명은 지중배전선 지지장치에 관한 것으로서, 지중에 매립되어 내부에 수용되는 고정대(20), 승강대(30), 부력체(40) 및 커넥터유닛(50) 그리고 전기적으로 연결되는 배전선(L)을 외력으로부터 보호하는 보호함(10); 지중에 매립된 보호함(10)의 내부 바닥면에 고정수단(예:앵커볼트)을 매개로 고정되는 고정대(20); 고정대(20)의 가이드봉(21)에 승강가능하게 설치되어 커넥터유닛(50)을 떠받치고, 내측으로 인입되는 케이블(C)을 안정적으로 지지 및 보호하는 승강대(30); 승강대(30)의 베이스(31) 하면에 부착 고정되어 물에 뜨는 부력체(40); 승강대(30)에 착탈가능하게 설치되어 보호함(10)을 통해 내측으로 인입된 배전선(L)을 전기적으로 상호 연결 및 고정하는 커넥터유닛(50);을 포함하는 것을 특징으로 한다. 본 실시 예에 의하면, 보호함의 내부로 침투수가 유입될 경우 부력체가 자연스럽게 승강하게 되고, 이에 의해 승강대에 설치되어 배전선을 전기적으로 상호 연결하고 있는 커넥터유닛이 승강하게 됨에 따라 침투수와의 접촉을 최소화할 수 있고, 이에 따라 침투수에 의한 전기합선과 같은 사고로부터 안전하게 배전선의 연결상태를 보호해 줄 수 있다.
