Description

지중배전용 케이블 방호장치{Protective apparatus for underground cable}Protective apparatus for underground cable {Protective apparatus for underground cable}

본 발명은 지중케이블을 보호하기 위한 지중배전용 케이블 방호장치에 관한 것으로서, 보다 상세하게는 지중에 매설된 케이블의 상부에 위치하여 굴착시 버킷으로부터의 충격에 의해 파열되면서 발광하여 작업자에게 지중케이블 매설위치를 알려주도록 한 지중배전용 케이블 방호장치에 관한 것이다.The present invention relates to a cable protection device for underground distribution to protect underground cables, and more particularly, located in the upper portion of the cable buried in the ground, and ruptures by the impact from the bucket during the excavation to bury the underground cable to workers It is related to underground cable protection device to indicate the location.

지중선로를 지중에 매설하는 이유는 안전성 및 단열성 때문이며, 지중에 장시간 동안 매설된 지중선로는 자체 노후에 의한 파손 및 침투수에 의해 부식되어 일정 시간이 지나면 보수하여야 하며, 이러한 노후 및 부식 등의 원인 외에도 증설 등의 이유에서 보수하는 경우도 있다.The underground line is buried under ground due to safety and heat insulation. The underground line embedded in the ground for a long time should be repaired after a certain time because it is corroded by damage and infiltration water caused by its own aging. In addition, repairs may be made for additional reasons.

이와 같이, 지중선로를 보수 및 교체하기 위해서는 지중선로가 매설된 지면을 굴착하여 지중선로를 외부로 노출시킨 다음 보수 및 교체작업을 수행한다.As described above, in order to repair and replace the underground line, the underground line is excavated to expose the underground line to the outside, and then the repair and replacement work is performed.

일반적인 굴착작업은 굴착기를 이용하여 빠르고 쉽게 수행하는데, 굴착기에 설치된 버킷으로 지면을 굴착한다. 이와 같이, 굴착작업이 수행되는 과정에서 굴착기의 운전자는 지중에 매설된 지중선로를 볼 수 없기 때문에 운전자의 감각으로 굴착작업을 수행한다. 운전자는 버킷이 지중선로에 닿는 충격을 감지하면 버킷을 이동시켜 버킷이 지중선로에 닿지 않도록 한 상태에서 굴착작업을 진행한다.The general excavation work is quick and easy by using an excavator, and the ground is excavated by the bucket installed in the excavator. As such, in the course of the excavation work, the driver of the excavator does not see the underground line buried in the ground, so the excavation work is performed with the driver's sense. When the driver senses the impact of the bucket on the underground track, the driver moves the bucket so that the bucket does not touch the underground track and proceeds with excavation.

그러나, 운전자가 지중선로의 위치를 알지 못한 상태에서 굴착작업을 수행하다 보면 굴착기의 버킷이 과도하게 지중선로를 가압하여 지중선로를 파괴시키는 경우가 종종 발생하며, 또한 운전자는 지중선로의 매설위치를 알지 못하기 때문에 지중선로를 따라 정확한 굴착위치를 설정하기 어려워 수시로 굴착진행방향을 수정하면서 굴착작업을 수행하여야 한다는 문제점이 있었다.However, when the driver performs the excavation work without knowing the location of the underground line, the excavator bucket often presses the underground line excessively and destroys the underground line. Since it is difficult to know the exact excavation position along the underground line, there was a problem that the excavation work should be performed while modifying the excavation progress direction from time to time.

본 발명은 상기와 같은 문제점을 해결하기 위하여 이루어진 것으로, 그 목적은 지중선로 굴착과정에서 굴착기의 버킷에 의해 지중선로가 파손되는 것을 방지할 수 있는 지중배전용 케이블 방호장치를 제공함에 있다.The present invention has been made to solve the above problems, and an object thereof is to provide a cable protection device for underground distribution, which can prevent the underground line from being damaged by the bucket of the excavator in the underground line excavation process.

이러한 본 발명의 목적을 달성하기 위하여 격자모양의 스크라이빙홈이 상면에 형성된 투명크랙판을 방호상자의 상부에 설치하고, 방호상자의 내측 중간에 설치되는 램프고정판에 전후좌우 일정한 간격으로 형성된 램프삽입구멍에 복수의 터치온램프를 삽입하며, 투명크랙판의 밑면을 지지하기 위한 보스를 램프고정판의 상면에 형성하여 지중배전용 케이블 방호장치가 제공된다.In order to achieve the object of the present invention, the transparent crack plate formed on the upper surface of the lattice-shaped scribing groove is installed on the upper part of the protective box, and the lamp is formed at regular intervals in front, rear, left and right on the lamp fixing plate installed in the inner middle of the protective box. A plurality of touch-on lamps are inserted into the holes, and a boss for supporting the bottom of the transparent crack plate is formed on the upper surface of the lamp fixing plate to provide a cable protection device for underground distribution.

이상에서 설명한 바와 같은 본 발명은 굴착기 운전자에게 지중선로의 위치를 시각적으로 알려줌으로써 지중선로의 파손을 방지할 수 있는 효과가 있으며, 더 나아가서는 야간 작업시 밝은 빛으로 지중선의 매설위치를 표시하기 때문에 식별력이 크게 향상되는 효과가 있다.The present invention as described above has an effect that can prevent the damage to the underground line by visually telling the excavator driver the position of the underground line, and furthermore because it displays the buried position of the underground line with bright light during night work Discernment is greatly improved.

이하 본 발명에 따른 작용을 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the operation according to the present invention will be described in detail with reference to the accompanying drawings.

첨부도면 도 1 내지 도 6에 도시된 바와 같이 방호상자(30)에 램프고정판(50)과 터치온램프(60) 및 투명크랙판(40)을 조립과정은 먼저 방호상자(30)의 내측벽면에 형성된 측면보스(30b)에 램프고정판(50)을 올린 다음 램프고정판(50)에 형성된 스크류구멍(50h)으로 볼트(30s)를 통과시켜 측면보스(30b)에 고정하게 되면 램프고정판(50)이 방호상자(30)에 견고하게 고정된다.As shown in FIGS. 1 to 6, the process of assembling the lamp fixing plate 50, the touch-on lamp 60, and the transparent crack plate 40 in the protective box 30 is first performed on the inner wall surface of the protective box 30. Raise the lamp fixing plate 50 to the side boss 30b formed in the lamp fixing plate 50 and then pass the bolt 30s through the screw hole 50h formed in the lamp fixing plate 50 to fix the side boss 30b. The protection box 30 is firmly fixed.

이후 램프고정판(50)에 형성된 램프삽입구멍(52)으로 터치온램프(60)의 램프하우징(61)을 삽입하게 되면, 램프하우징(61)의 외주면에 형성되어 있는 일방향걸림돌기(63)가 램프삽입구멍(52)을 통과하여 램프삽입구멍(52)의 하단에 걸리는 동시에 램프하우징(61)의 상단에 형성되어 있는 플랜지(62)는 램프삽입구멍(52)의 상단에 걸린다.Then, when the lamp housing 61 of the touch-on lamp 60 is inserted into the lamp insertion hole 52 formed in the lamp fixing plate 50, the one-way locking protrusion 63 formed on the outer circumferential surface of the lamp housing 61 is formed. The flange 62 formed at the upper end of the lamp housing 61 while being caught by the lower end of the lamp insertion hole 52 through the lamp insertion hole 52 is caught by the upper end of the lamp insertion hole 52.

이와 같이 램프고정판(50)에 여러개 형성되어 있는 램프삽입구멍(52)에 모두 터치온램프(60)를 결합한 상태에서 투명크랙판(40)을 방호상자(30)의 상단에 결합하게 되면, 투명크랙판(40)의 밑면 가장자리에 형성되어 있는 사각리브(40r)가 방호상자(30)의 상단 내측에 삽입되면서 걸린다.When the transparent crack plate 40 is coupled to the upper end of the protective box 30 in a state in which both the touch-on lamps 60 are coupled to the lamp insertion holes 52 formed in the lamp fixing plate 50 as described above, The rectangular rib 40r formed at the bottom edge of the crack plate 40 is caught while being inserted into the upper inside of the protective box 30.

이때 투명크랙판(40)의 사각리브(40r)와 방호상자(30)의 상단부에 접착제를 도포한 상태로 결합하게 되면 투명크랙판(40)를 방호상자(30)에 영구적으로 결합할 수 있게 된다.At this time, when the adhesive is applied to the rectangular rib 40r of the transparent crack plate 40 and the upper end of the protective box 30, the transparent crack plate 40 can be permanently coupled to the protective box 30. do.

위와 같이 조립된 지중배전선로 방호장치를 지중케이블(20)을 수용하고 있는 파형관(22) 상측에 설치하는 과정은 방호상자(30)의 하부에 형성된 다리부(32)를 지중에 설치된 파형관(22)과 홈부(24)에 끼워맞추게 되면, 방호상자(30)가 파형관(22)의 상부에 위치된다.The process of installing the underground distribution line protection device assembled as above on the corrugated pipe 22 accommodating the underground cable 20 includes the corrugated pipe 22 installed in the ground with the leg 32 formed on the lower portion of the protective box 30. ) And the groove 24, the protective box 30 is located above the corrugated pipe (22).

이후 투명크랙판(40)을 흙으로 덮어도 토압에 견디도록 되어 있으므로, 파손되지 않고 방호상자(30)의 내부에 위치된 터치온램프(60)를 수분이나 토사로부터 보호하는 작용을 하게 된다.Since the transparent crack plate 40 is covered with soil, so that it withstands earth pressure, thereby preventing the touch-on lamp 60 located inside the protective box 30 from being damaged or soiled without being damaged.

또한, 첨부도면 도 5에 도시된 바와 같이 슬라이딩렌즈(66)에 아무런 외력이 작용되지 않는 한 슬라이딩렌즈(66)와 어퍼스프링시트(67), 발광다이오드모듈(72) 및 가동접점(76)은 스프링(70)의 자유높이에서 머물게 되어 가동접점(76)이 고정접점(74)과 이격된 상태를 유지하게 되며, 배터리(65)로부터 고정접점(74)과 가동접점(76)을 거쳐 발광다이오드모듈(72)로 공급되는 전류공급이 차단되어 발광다이오드모듈(72)이 소등된 상태를 유지하게 된다.5, as long as no external force is applied to the sliding lens 66, the sliding lens 66, the upper spring sheet 67, the light emitting diode module 72, and the movable contact 76 are provided. Staying at the free height of the spring 70 to maintain the movable contact 76 is spaced apart from the fixed contact 74, the light emitting diode from the battery 65 via the fixed contact 74 and the movable contact 76 The current supply to the module 72 is cut off so that the light emitting diode module 72 is turned off.

위와 같은 상태에서 지중에 매설된 케이블을 점검하거나 보수하기 위해 굴착작업을 진행하면서 굴착기의 버킷이 투명크랙판(40)을 가격하게 되면, 투명크랙판(40)에 형성된 스크라이빙홈(42)에 의해 작은 충격에도 투명크랙판(40)이 쉽게 파손된다.When the bucket of the excavator hits the transparent crack plate 40 while the excavation work is carried out to check or repair the cable buried in the ground in the above state, the scribing groove 42 formed in the transparent crack plate 40 As a result, the transparent crack plate 40 is easily broken even with a small impact.

첨부도면 도 6에 도시된 바와 같이 파손된 투명크랙판(40)이 아래쪽으로 내려가면서 하측에 위치된 터치온램프(60)의 슬라이딩렌즈(66)를 아래쪽 누르게 되며, 하측으로 힘을 받은 슬라이딩렌즈(66)는 어퍼스프링시트(67)와 발광다이오드모듈(72) 및 가동접점(76)과 함께 아래쪽으로 움직이게 된다.As shown in FIG. 6, the broken transparent crack plate 40 is pushed downward while pressing down the sliding lens 66 of the touch-on lamp 60 located at the lower side, and the sliding lens applied downward. 66 moves downward with the upper spring sheet 67, the light emitting diode module 72, and the movable contact 76.

이때 슬라이딩렌즈(66)의 외측면에 형성되어 있는 직선안내리브(66k)가 램프하우징(61)의 내측면에 형성되어 있는 직선안내홈(66m)을 따라 미끄러지면서 슬라이딩렌즈(66)와 어퍼스프링시트(67), 발광다이오드모듈(72) 및 가동접점(76)의 회전이 방지된다.At this time, the linear guide ribs 66k formed on the outer surface of the sliding lens 66 slide along the linear guide grooves 66m formed on the inner surface of the lamp housing 61, and the sliding lens 66 and the upper spring. Rotation of the sheet 67, the light emitting diode module 72 and the movable contact 76 is prevented.

즉, 가동접점(76)이 고정접점(74)을 향해 아래쪽으로 향할 때 회전되면 접점의 극성이 바뀔뿐 아니라 접촉불량이 발생될 수 있으므로, 슬라이딩렌즈(66)와 램프하우징(61)에 각각 직선안내리브(66k)와 직선안내홈(66m)을 둔 것이다.That is, when the movable contact 76 is rotated downward toward the fixed contact 74, not only the polarity of the contact is changed but also contact failure may occur, so that each of the straight lines of the sliding lens 66 and the lamp housing 61 is linear. Guide ribs 66k and straight guide grooves 66m.

위와 같이 파단된 투명크랙판(40)에 의해 슬라이딩렌즈(66)가 아래쪽으로 힘을 받을 때 어퍼스프링시트(67)와 로워스프링시트(69) 사이에 위치되어 있던 스프링(70)은 압축되어 복원에 필요한 탄성에너지를 갖게 되며, 가동접점(76)이 고정접점(74)에 접촉되는 순간, 배터리(65)로부터 고정접점(74)과 가동접점(76)을 통해 발광다이오드모듈(72)로 전류가 공급되어 발광다이오드모듈(72)이 점등된다.When the sliding lens 66 is pushed downward by the transparent crack plate 40 broken as described above, the spring 70 positioned between the upper spring sheet 67 and the lower spring sheet 69 is compressed and restored. It has the elastic energy required for the current, and at the moment when the movable contact 76 is in contact with the fixed contact 74, the current from the battery 65 to the light emitting diode module 72 through the fixed contact 74 and the movable contact 76 Is supplied to turn on the LED module 72.

이때 발광다이오드모듈(72)로부터 발광되는 빛은 슬라이딩렌즈(66)와 파단된 투명크랙판(40)을 투과하여 외부로 방사되어 굴착 작업자가 눈으로 보고 지중선이 매설된 곳임을 알 수 있게 된다.At this time, the light emitted from the light emitting diode module 72 is transmitted through the sliding lens 66 and the broken transparent crack plate 40 is radiated to the outside so that the excavation worker sees the eye can see that the underground line is embedded.
