도 5는 본 발명에 따른 지중전선 보호용 전선배관의 고정체의 작용을 나타낸 작동도로서, 도 5을 참조하여 본 발명에 따른 지중전선 보호용 전선배관의 고정체의 작용을 설명하면 다음과 같다.5 is an operation diagram showing the action of the fixture of the underground wire protection wire pipe according to the present invention, the operation of the fixture of the underground wire protection wire pipe according to the present invention with reference to FIG.

상기 배전반(20)에 화재가 발생하면, 화재감지센서(90)는 제어유닛(90)으로 화재신호를 송신하고, 이를 수신한 제어유닛(90)은 구동모터(73)를 구동시킨다. When a fire occurs in the switchboard 20, the fire detection sensor 90 transmits a fire signal to the control unit 90, the control unit 90 receives the drive motor 73.

상기 구동모터(73)가 작동하면, 스크류축(72)이 회전하면서 너트(74)를 구비한 타격부(75)가 좌측으로 이동하여, 지중배관(30)을 수평으로 가로지른다.When the drive motor 73 is operated, the screw shaft 72 is rotated to move the striking portion 75 with the nut 74 to the left to cross the underground pipe 30 horizontally.

이때, 상기 타격부(75)가 연결대(60)의 절개홈(61)에 닿으면서 연결대(60)를 좌측으로 밀고 들어가면, 연결대(60)의 양단이 지지대(S,S')에 의해 지지되면서 상대적으로 취약한 절개홈(61)이 끊어진다. 따라서, 배전반전력공급선(40)과 외부전력공급선(50)의 전기적 연결이 끊어진다.At this time, when the striking portion 75 pushes the connecting rod 60 to the left while touching the cutting groove 61 of the connecting rod 60, both ends of the connecting rod 60 are supported by the support (S, S '). Relatively weak incision groove 61 is broken. Therefore, the electrical connection between the switchboard power supply line 40 and the external power supply line 50 is cut off.

이후, 계속적으로 진행하는 타격부(75)는 지중배관(30)의 삽입부(32)에 삽입되면서 지중배관(30)을 밀폐시켜 배전반(20)에 발생 된 화염이 지중배관(30)을 따라 더 이상 진행되지 않는다.
