Abstract

A leakage checking device of an underground cable pipe prevents permeation of water by reinforcing a connection part of the cable pipe through a pipe connector. A case is installed between cable pipes(3) which are laid under the ground. A transparent rectangular parallelepiped case(10) protects the cable passing through the inside with the cable pipe. A magnesium block of a rectangular parallelepiped shape is inserted and fitted between the cables inside the case. One side of a pair of cylindrical pipe connectors is screw-coupled to the cable pipe and other side of the cylindrical pipe connectors is inserted into the case. The cylindrical pipe connectors connect the cable pipe and the case. An inspection pipe(40) includes a lens and is installed to observe the inside of the case by exposing a cap(49) of the top end portion on the ground surface.

Description

지중 케이블배관의 침수점검장치{Device for Leakage Check in Underground Cable Pipe}Device for Leakage Check in Underground Cable Pipe

본 발명은 지중에 매설된 케이블배관의 침수 여부를 점검할 수 있는 장치에 관한 것으로서, 더욱 상세하게는 고압케이블을 보호하기 위하여 지중에 설치되어 있는 케이블배관의 연결부위를 보강하여 물이 침투하는 것을 방지함과 동시에, 연결부위의 침수여부를 육안으로 외부에서 쉽게 확인하고 신속한 후속조치를 취할 수 있도록 한 지중 케이블배관의 침수점검장치에 관한 것이다.The present invention relates to a device that can check the flooding of the cable pipes buried in the ground, more specifically, to protect the high-voltage cable to reinforce the connection portion of the cable pipes installed in the ground to protect the penetration of water At the same time, the present invention relates to a submerged inspection apparatus for underground cable piping, which enables the naked eye to easily check whether the connection part is inundated with the naked eye and take quick follow-up measures.

각 가정이나 사무실 등에서 사용되는 전기는 각 지역별로 건설되어 있는 변전소에서 고전압으로 분배되어 각 지역이나 건물 등에 마련되어 있는 변압기를 거쳐 일반적으로 사용되는 저전압으로 변압되어 공급되고 있다.Electricity used in each home or office is distributed to high voltage in substations constructed in each region, and is transformed and supplied to low voltage generally used through transformers provided in each region or building.

이와 같이 분배되는 케이블은 안전과 미관을 고려하여 지상에 설치하지 않고 지하에 매설하고 있으며, 이 경우 케이블이 외부로부터 안전하게 보호받을 수 있도록 케이블배관을 지하에 매설하고 그 내측으로 케이블을 내입하여 배선한다.The cables distributed in this way are buried underground without being installed on the ground in consideration of safety and aesthetics.In this case, the cable pipes are buried underground and the cables are inserted inside the wiring so that the cables can be safely protected from the outside. .

상기 케이블배관은 일정규격으로 제조되고 있어서 배선되는 케이블의 길이에 따라 다수 개를 연속하여 설치하여야 하는데, 이 경우 케이블배관의 연결부위로 수 분이 침투하여 고압케이블의 누전이나 쇼트가 발생되는 문제점이 자주 발생하였다.Since the cable piping is manufactured to a certain standard, a plurality of cables should be installed continuously according to the length of the cable to be wired. In this case, a problem of frequent leakage or short circuit of a high-voltage cable is caused by penetration of moisture into the connection portion of the cable piping. Occurred.

이러한 문제점을 해결하기 위한 방안으로, 국내 특허등록번호 제10-0712315호에는 "건축 전기배관 누수 방지시설구조"가 개시되어 있는데, 상기 특허는 내부로 고압케이블이 관통되는 전기배관의 단부에 회전 가능하게 형성되며 내면에 나사산이 형성되어 있는 체결부재와, 일측 내면에는 어느 하나의 전기배관의 일측이 삽입되고 타측 내면에는 상기 전기배관과 연결되는 다른 전기배관의 일측이 삽입되며 외주면에는 나사산이 형성되어 상기 체결부재가 체결되는 연결관과, 상기 체결부재와 상기 연결관 사이에 개재되는 패킹부재로 구성되어 있다.In order to solve this problem, Korean Patent Registration No. 10-0712315 discloses a "building electrical pipe leakage preventing facility structure", the patent can be rotated at the end of the electrical pipe through which the high-voltage cable penetrates inside And a fastening member having a screw thread formed on the inner surface thereof, and one side of one of the electrical pipes is inserted into one inner surface, and one side of the other electrical pipe connected to the electrical pipe is inserted into the other inner surface and a thread is formed on the outer circumferential surface thereof. Consists of a connecting pipe to which the fastening member is fastened, and a packing member interposed between the fastening member and the connecting pipe.

상기와 같이 구성된 특허는 연결부위로 습기나 물이 침투하는 것을 방지함과 동시에 보강시키는 것으로 개시되어 있으나, 단순히 전기배관들 사이의 연결부위에 기밀과 보강을 위해 연결관으로 연결한 것으로서, 연결부위 내부의 누수 여부를 확인할 수 없으므로, 장기간의 경과로 인한 손상이나 지반의 침하 등에 의해 연결관이 손상될 경우 이를 미리 파악할 수가 없어서 결과적으로 누전이나 쇼트가 발생하게 되는 문제점이 있다.Patents configured as described above are disclosed to prevent the penetration of moisture or water into the connection portion and at the same time reinforcement, but simply connected to the connection portion between the electrical pipes for airtightness and reinforcement, the connection portion Since it is not possible to check whether there is a leak inside, if the connection pipe is damaged by damage or settlement of the ground due to prolonged period of time, it may not be grasped in advance, resulting in a short circuit or short circuit.

따라서, 상기와 같은 문제점을 해결하기 위한 본 발명의 기술적 과제는 고압케이블을 보호하기 위하여 지중에 설치되어 있는 케이블배관의 연결부위를 보강하여 물이 침투하는 것을 방지하고, 연결부위의 침수 여부를 외부에서 쉽게 육안으로 확인할 수 있는 지중 케이블배관의 침수점검장치를 제공하는 것이다.Therefore, the technical problem of the present invention for solving the above problems is to reinforce the connection part of the cable pipe installed in the ground to protect the high-voltage cable to prevent water from penetrating, and whether the connection part is flooded outside It is to provide a submerged inspection device for underground cable piping that can be easily identified with the naked eye.
