The display member 600 is a sheet of flexible synthetic resin material, the scale indicating the length is displayed in the vertical direction, the lower end is fixed to the upper surface of the underground pipe (2) is arranged upwardly extended. In this case, the display member 600 has a plurality of cutouts 610 in the vertical direction at regular intervals, and the cutouts 610 are cutout portions of the display member 600 that are torn by the bucket of the excavator during the excavation. 610 to prevent the further progression to prevent the entire cover member 600 is torn.

상기 화재감지기구(700)는 스틸 재료의 연기통로관(710)과 연기통로관(710)을 통해 빠져나온 연기를 감지하는 연기감지센서(720)로 구성된다.The fire detection mechanism 700 is composed of a smoke detection sensor 720 for detecting the smoke exiting through the smoke passage pipe 710 and the smoke passage pipe 710 of the steel material.

상기 연기통로관(710)은, 상하단이 개구되며, 상단이 외부케이스(200) 내부로 연장되고 하단이 지중배관(2)의 내관(2a) 내부로 노출되도록 수직방향으로 입설된다. 이때 연기통로관(710)의 하단에는 합성수지와 같이 열에 약한 폐쇄막(711)이 설치되어 하단이 밀폐된다. 이때 폐쇄막(711)은 지중배관(2) 내부로 이물질이 들어가는 것을 방지한다.The smoke passage pipe 710 is opened in the vertical direction so that the upper and lower ends are opened, the upper end is extended into the outer case 200 and the lower end is exposed to the inner tube (2a) of the underground pipe (2). At this time, the lower end of the smoke passage pipe 710 is closed with a closed membrane 711 that is weak in heat, such as synthetic resin. At this time, the closed membrane 711 prevents foreign matter from entering the underground pipe 2.

상기 연기감지센서(720)는 연기의 발생여부를 감지하는 통상적인 연기감지센서로서, 연기통로관(710)의 상단의 상방향에 위치되도록 외부케이스(200)에 내설되며, 제어유닛(800)과 연결된다. 따라서, 지중배관(2) 내부에 화재가 발생할 시, 연기감지센서(720)는 연기통로관(710)을 통해서 외부케이스(200)로 배출되는 연기를 감지하여 제어유닛(800)에 화재발생신호를 송출한다. The smoke detection sensor 720 is a conventional smoke detection sensor for detecting whether the smoke is generated, is installed in the outer case 200 to be located in the upper direction of the upper end of the smoke passage pipe 710, the control unit 800 Connected with Therefore, when a fire occurs inside the underground pipe 2, the smoke detection sensor 720 detects the smoke discharged to the outer case 200 through the smoke passage pipe 710 to the fire generating signal to the control unit 800 Send the.

상기 제어유닛(800)은 연기감지센서(720)로부터 화재발생신호를 수신한 후, 중앙통제실에 있는 수신기(H)로 그 신호를 송출한다. 이때 디스플레이장치와 연결된 수신기(H)는 화재가 발생했다는 사실을 디스플레이장치에 나타낸다. The control unit 800 receives the fire occurrence signal from the smoke detection sensor 720, and then sends the signal to the receiver (H) in the central control room. At this time, the receiver H connected to the display device indicates to the display device that a fire has occurred.

도 5는 본 발명에 따른 매설형 배전선의 배관연결구조의 작동상태를 나타낸 것으로, 도 5를 참조하여 본 발명에 따른 매설형 배전선의 배관연결구조의 작동상 태를 설명하면 다음과 같다.5 is a view illustrating an operation state of a pipe connection structure of a buried type distribution line according to the present invention. Referring to FIG. 5, an operation state of a pipe connection structure of a buried type distribution line according to the present invention is as follows.

도 1과 같이 지지기구(100)가 스프링(140)이 압축된 상태로 지중배관(2)을 지지하고, 에어탱크(300)에는 고압의 압축공기가 충진되어 있으며, 화재감지기구(700)가 구비된 상태에서, 지중배관(2)의 하부로 흐르는 물에 의해 지중배관(2)의 하부에 위치한 토사가 쓸려나가게 되면, 하부지지대(130)는 하측으로 하강된다. 이때 하부지지대(130)가 하강하더라도, 스프링(140)이 신장되어 상부지지대(120)를 지속적으로 상향가압하며, 이에 따라 지중배관(2)을 계속적으로 지지할 수 있다. As shown in FIG. 1, the support mechanism 100 supports the underground pipe 2 while the spring 140 is compressed, and the air tank 300 is filled with high-pressure compressed air, and the fire detection mechanism 700 is In the provided state, when the earth and sand located in the lower portion of the underground pipe 2 is swept away by the water flowing down the underground pipe 2, the lower support 130 is lowered. At this time, even if the lower support 130 is lowered, the spring 140 is extended to continuously press the upper support 120, thereby supporting the underground pipe (2) continuously.

그리고, 하부지지대(130)가 하강됨에 따라, 제1·2와이어(400,400')이 하측으로 당겨져 하강되며, 에어탱크(300)의 밸브(310,310')가 열리면서 압축된 공기가 챔버(230)로 배출된다. 배출된 공기는 통공(250)을 통해 에어백(500)의 내부로 유입되고, 유입된 공기에 의해 에어백(500)이 부풀어 오른다. 따라서 인근에 있는 작업자가 지중배관(2)의 하부토사가 유실되었음을 인식할 수 있다. Then, as the lower support 130 is lowered, the first and second wires 400 and 400 'are pulled downward and lowered, and the compressed air flows into the chamber 230 while the valves 310 and 310' of the air tank 300 are opened. Discharged. The discharged air is introduced into the airbag 500 through the through hole 250, and the airbag 500 is inflated by the introduced air. Therefore, a worker in the vicinity can recognize that the bottom soil of the underground pipe (2) has been lost.

또한, 지중배관(2)의 내부 케이블(C)에 화재가 발생하였을 시, 그 열에 의해 폐쇄막(711)은 녹아 내려 연기통로관(710)의 하단부가 개구되고, 화재로 발생된 연기가 개구된 연기통로관(710)을 통해서 외부케이스(200)로 배출된다. 따라서, 연기감지센서(1020)가 연기를 감지하여 화재발생신호를 제어유닛(800)에 송신하고, 이 화재발생신호를 받은 제어유닛(800)은 중앙통제실의 수신기(H)에 신호를 전송한다. 따라서 지중배관(2) 내부에 화재발생하였음이 수신기(H)에 연결된 중앙통제실의 디스플레이에 나타나게 된다. In addition, when a fire occurs in the inner cable C of the underground pipe 2, the closing film 711 melts due to the heat, and the lower end of the smoke passage pipe 710 is opened, and the smoke generated by the fire is opened. It is discharged to the outer case 200 through the smoke passage pipe 710. Accordingly, the smoke detection sensor 1020 detects the smoke and transmits a fire generation signal to the control unit 800, and the control unit 800 receiving the fire generation signal transmits a signal to the receiver H of the central control room. . Therefore, the fire occurred in the underground pipe 2 is shown on the display of the central control room connected to the receiver (H).

그리고, 지중배관(2)이 파손될 시, 작업자는 지중배관(2)의 배치위치를 정확 히 알 지 못한 상태에서 굴삭기를 이용하여 지면을 파고 내려간다. 이때 지중배관(2)에 근접한 곳까지 파 내려가면 표시부재(600)가 노출되므로, 작업자는 표시부재(600)의 눈금을 확인하여 지중배관(2)까지의 남은 깊이를 확인할 수 있다. And, when the underground pipe (2) is broken, the worker digging down the ground using an excavator in a state that does not know the exact position of the underground pipe (2). At this time, since the display member 600 is exposed when it is dug to a place close to the underground pipe 2, the operator can check the scale of the display member 600 to check the remaining depth to the underground pipe 2.

상술한 바와 같이 본 발명에 따른 지중배전용 케이블의 배선구조는, 지중배관(2)보다 아래에 위치한 지반이 지하수등에 의해 세굴되었을 시, 그 상황을 즉각적으로 확인할 수 있으며, 에어백(500)을 통해 토사유실유무를 쉽게 확인할 수 있고, 배관파손확인부재(700)를 통해 지중배관(2) 균열 여부를 파악할 수 있으며, 보수작업시 굴착작업으로 인한 지중배관(2)의 파손을 방지할 수 있다. As described above, in the wiring structure of the underground distribution cable according to the present invention, when the ground located below the underground pipe 2 is scoured by groundwater or the like, the situation can be checked immediately, and through the airbag 500. The presence or absence of soil loss can be easily confirmed, the pipe damage check member 700 can determine whether the underground pipe (2) cracks, and can prevent damage to the underground pipe (2) due to excavation work during maintenance work.
