Description

Underground Line Tray Equipment [0002]

본 발명은 지중배전선 지지 트레이기구에 관한 것이다.The present invention relates to an underground distribution line support tray mechanism.

최근에 산업화가 가속됨에 따라 전력 사용량이 급속도로 증가하고 있는 실정이며, 이들의 공급은 배전케이블을 통해 생산지로부터 소비지로 공급되고, 이러한 케이블들은 도시 미관 및 사람이나 차량의 이동장해 등 여러 가지를 고려하여 지중에 매설된다.Recently, as the industrialization has accelerated, the power consumption is rapidly increasing. The supply of these is supplied from the production area to the consuming area through the distribution cable. These cables are considered various aspects such as the urban beauty and the movement of persons and vehicles And buried in the ground.

이와 같이 지중에 매설되는 지중배전선은 전력구와 전력구 사이에 설치되는 맨홀 내부에서 노출되어 서로 연결된다.In this way, underground distribution lines buried in the ground are exposed and connected to each other in a manhole installed between the electric power and electric power.

그러나, 종래에는 도 1에 도시된 바와 같이 맨홀(MH) 바닥에 설치되는 지지대(1)를 통해 지중배전선(L)을 지지하여 공간활용도가 낮았으며, 지중배전선(L)의 연결 위치(고저)에 따라 지지대의 위치를 조절할 수 없었다.Conventionally, as shown in FIG. 1, the underground distribution line L is supported through the support 1 installed on the floor of the manhole MH, so that the space utilization is low and the connection position (bottom) of the underground distribution line L is low. It was not possible to adjust the position of the support.

또한, 종래에는 맨홀(MH) 내부를 조명할 수 없어, 지중배전선(L)을 수리하는 데 있어 어려움이 있었다.In addition, conventionally, the inside of the manhole MH can not be illuminated, which makes it difficult to repair the underground distribution line L.

그리고, 종래에는 지진에 의해 지면이 흔들릴 시, 지중배전선(L) 간의 연결이 쉽게 단선되어 전력의 안정적 공급에 어려움이 있었다.In the past, when the ground is shaken by an earthquake, the connection between the underground distribution lines L is easily broken, which makes it difficult to stably supply the electric power.

한편, 강도가 큰 지진이 발생할 시, 지중배전선(L) 간의 전기적 연결을 차단하는 것이, 누전 발생에 대비해, 오히려 안전할 수 있다.On the other hand, when an earthquake of high strength occurs, it is rather safe to cut off the electrical connection between underground distribution lines (L) in preparation for occurrence of a short circuit.

따라서, 일정 기준 이하의 진동에서는 안정적으로 전력을 연결하고, 일정 기준 이상의 진동에서는 전력을 차단할 수 있는 발명의 필요성이 요구되고 있는 실정이다Therefore, there is a need for an invention that can stably connect electric power at a vibration below a predetermined standard and cut off power at a vibration exceeding a certain standard

도 7 내지 도 20은 본 발명에 따른 지중배전선 지지 트레이기구의 작용을 설명하기 위한 도면으로, 도 7 내지 도 20을 참조하여 본 발명에 따른 지중배전선 지지 트레이기구의 작용을 설명하면 다음과 같다.FIGS. 7 to 20 are views for explaining the operation of the underground distribution line support tray mechanism according to the present invention, and the operation of the underground distribution line support tray mechanism according to the present invention will be described with reference to FIG. 7 to FIG.

도 7에 도시된 바와 같이 제1,2안착기구(50,60)의 받침체(52,62)를 회전시켜 상하 이동시킴으로써, 지중배전선(L)의 설치 위치에 맞게 상기 받침체(52,62)의 높이를 조절한다. 그리고 제1,2절연부재(21,22)를 제1,2안착기구(50,60)에 각각 설치한다. 이후 지중배전선(L)이 연결된 제1,2접속부재(31,32)가 서로 맞닿도록 도 8에 도시된 바와 같이 제1,2절연부재(21,22)를 체결한다. 이때 제1,2접속부재(31,32)의 제1,2걸림부(31a,32a)는 제1,2스프링(33,34)의 탄발력에 의해 서로 맞닿아 안정적인 배전이 이루어진다.The support bodies 52 and 62 of the first and second seating mechanisms 50 and 60 are rotated to move the support bodies 52 and 62 in accordance with the installation position of the underground distribution line L, ). The first and second insulating members 21 and 22 are installed in the first and second seating mechanisms 50 and 60, respectively. Then, the first and second insulating members 21 and 22 are fastened as shown in FIG. 8 so that the first and second connecting members 31 and 32 connected to the underground distribution line L are in contact with each other. At this time, the first and second fastening portions 31a and 32a of the first and second connecting members 31 and 32 come into contact with each other due to the elastic force of the first and second springs 33 and 34, thereby achieving stable power distribution.

또한, 도 2에 도시된 바와 같이 본 발명이 설치된 상태에서 커버기구(20), 커넥팅기구(30), 고정기구(40)를 수리할 시, 작업자는 조명체(12)의 조도 정도에 따라 도 9에 도시된 바와 같이 조명기구(10)의 상하 좌우 위치를 조절함으로써, 도 10에 도시된 바와 같이 작업자가 원하는 조도 및 방향으로 조명체(12)를 조명한다.2, when the cover mechanism 20, the connecting mechanism 30, and the fixing mechanism 40 are repaired in the state where the present invention is installed, the operator can adjust the degree of illuminance of the illuminator 12 9, the operator illuminates the illuminator 12 at a desired illuminance and direction as shown in Fig. 10 by adjusting the up-and-down and left-right positions of the illuminator 10 as shown in Fig.

한편, 도 2와 같이 본 발명에 지중배전선(L)이 설치된 상태에서, 약한 지진에 의해 본 발명의 지중배전선 지지 트레이기구 및 지중배전선(L)에 횡력이 전달될 시, 제1,2안착기구(50,60)가 좌우로 흔들리면 도 11에 도시된 바와 같이 제1,2접속부재(31,32)도 함께 흔들린다. 이때 제1,2접속부재(31,32)는 제1,2스프링(33,34)에 의해 완충되면서 접속을 유지하여 배전이 지속적으로 유지되도록 한다.On the other hand, when the underground distribution line L is installed in the present invention as shown in FIG. 2, when a lateral force is transmitted to the underground distribution line support tray mechanism and the underground distribution line L of the present invention by the weak earthquake, The first and second connecting members 31 and 32 shake together as shown in FIG. At this time, the first and second connecting members (31, 32) are buffered by the first and second springs (33, 34) to maintain the connection so that power distribution is continuously maintained.

한편, 약한 지진의 경우 상기와 같이 제1,2접속부재(31,32)를 완충하면서 접속을 유지하는 것이 바람직하지만, 강한 지진이 발생할 경우 혹시 모를 안전사고(예를 들어 누전 발생)에 대비해 물리적으로 단전을 시키는 것이 바람직할 수 있다.Meanwhile, in the case of a weak earthquake, it is preferable to maintain the connection while buffering the first and second connecting members 31 and 32 as described above. However, in case of a strong earthquake, in case of a safety accident (for example, It may be desirable to provide a short circuit.

따라서, 본 발명은 강한 지진이 발생하여, 제1,2접속부재(31,32)가 일정 기준이상 이동할 경우, 제1,2접속부재(31,32)의 접속을 끊을 수 있다. Accordingly, in the present invention, when a strong earthquake occurs and the first and second connecting members 31 and 32 move by a predetermined reference or more, the first and second connecting members 31 and 32 can be disconnected.

여기서, 제1,2접속부재(31)의 접속 차단은 제1절연부재(21), 제1접속부재(31), 제1고정부재(41)을 대상으로 설명하고, 이외에 하기에서 본 발명의 작용 설명 또한 제1절연부재(21), 제1접속부재(31), 제1고정부재(41)을 대상으로 설명한다.Hereinafter, the first and second connecting members 31 and 31 will be described with reference to the first insulating member 21, the first connecting member 31, and the first fixing member 41, Operation Explanation is also made for the first insulating member 21, the first connecting member 31, and the first fixing member 41. [

본 발명은 도 12에 도시된 바와 같이 제1,2접속부재(31,32)가 일정 기준 이상 우방으로 이동하면, 제2접속부재(32)의 걸림부(32a)가 제2절연부재(22)의 걸림공간(22c)을 이루는 면에 걸린다.12, when the first and second connecting members 31 and 32 are moved to a predetermined reference or more, the engaging portion 32a of the second connecting member 32 is inserted into the second insulating member 22 And the engaging space 22c of the engaging portion 22c.

이때, 제1접속부재(31)는, 우방으로 지속적으로 이동하게 되어, 도 12에 도시된 바와 같이 제2접속부재(32)와의 접속이 끊어지고, 제1접속부재(31)의 걸림턱(31c1)이 제1고정부재(41)의 걸림부(41b1)에 걸린다. 그러면 제1,2접속부재(31,32)가 서로 이격되어 단전 상태가 유지된다.At this time, the first connecting member 31 is continuously moved to the right to disconnect the second connecting member 32 as shown in Fig. 12, and the engaging jaws of the first connecting member 31 31c1 are caught by the engaging portion 41b1 of the first fixing member 41. [ Then, the first and second connecting members 31 and 32 are spaced apart from each other to maintain the uninterrupted state.

또한, 본 발명의 고정기구(40)는 장기간 설치로 인해, 제1고정부재(41)의 스프링(41c)의 탄성력이 약해져, 제1고정부재(41)의 걸림체(41b)의 위치가 하방으로 이동할 수 있다.The elastic force of the spring 41c of the first fixing member 41 is weakened due to the long-time installation of the fixing mechanism 40 of the present invention, so that the position of the locking member 41b of the first fixing member 41 is lower . &Lt; / RTI >

예를 들어, 도 13에 도시된 바와 같이 제1고정부재(41)의 걸림체(41b)가 하방으로 이동하여, 걸림 기능에 문제가 발생할 수 있다.For example, as shown in Fig. 13, the stopper 41b of the first fixing member 41 may move downward, which may cause a problem in the latching function.

이때, 본 발명은, 작업자가 본 발명의 지중배전선 지지 트레이기구를 점검할 시, 제1고정부재(41)의 표식판(41e)과 제1고정부재(41)의 마개(41a) 간의 거리 변화(도 13의 a ---> b)를 확인하거나, 제1고정부재(41)의 볼트바(41d)를 잡아당겨(도 13의 화살표 참조) 탄성력을 확인함으로써, 제1고정부재(41)의 걸림체(41b)의 위치 변화를 점검할 수 있다. 여기서 제1고정부재(41)의 볼트바(41d)를 잡아 당길 시 제1고정부재(41)의 표식판(41e)은 손잡이 역할을 할 수도 있다.At this time, according to the present invention, when the operator checks the underground distribution line support tray mechanism of the present invention, the distance between the marking plate 41e of the first fixing member 41 and the stopper 41a of the first fixing member 41 (See a-> b in Fig. 13) or by pulling the bolt bar 41d of the first fixing member 41 (see the arrow in Fig. 13) It is possible to check the positional change of the stopper 41b. Here, when the bolt bar 41d of the first fixing member 41 is pulled, the marking plate 41e of the first fixing member 41 may serve as a knob.

이와 같이 작업자가 점검을 할 시, 작업자는 제1고정부재(41)의 스프링(41c)의 탄성력 변화가 크기 않다고 판단되면, 도 14에 도시된 바와 같이 제1고정부재(41)의 마개(41a)를 상방으로 이동시켜 제1고정부재(41)의 걸림체(41b)가 제1접속부재(31)의 지중배전선연결부(31c)에 맞닿게 한 후, 도 15에 도시된 바와 같이 제1고정부재(41)의 마개(41a)를 더욱 상방으로 이동시켜 제1고정부재(41)의 스프링(41c)이 압축되도록 한다.14, when the worker performs the inspection as described above, when the operator determines that the change in the elastic force of the spring 41c of the first fixing member 41 is insignificant, the operator stops the stopper 41a of the first fixing member 41 To move the stopper 41b of the first fixing member 41 against the underground distribution line connecting portion 31c of the first connecting member 31 and then to fix the first fixing member 41 as shown in Fig. The stopper 41a of the member 41 is further moved upward so that the spring 41c of the first fixing member 41 is compressed.

이때, 작업자는 상기와 같이 임시로 제1고정부재(41)의 스프링(41c)의 압축시켜, 갑자기 발생할 수 있는 지진에 대비해 임시 조치를 취한 후, 다수의 지중배전선 지지 트레이기구의 점검이 끝나면, 상기 제1고정부재(41)를 교체한다.At this time, the operator temporarily compresses the spring 41c of the first fixing member 41 as described above, and after temporary measures are taken in preparation for an earthquake that may occur suddenly, when a plurality of underground distribution line support tray mechanisms are inspected, The first fixing member 41 is replaced.

한편, 강한 지진이 발생하여 제1고정부재(41)가 작동할 시, 정상적이라면 도 12에 도시된 바와 같이 제1고정부재(41)가 작동해야 하지만, 제1고정부재(41)의 문제로 인해 도 16에 도시된 바와 같이 제1고정부재(41)의 걸림부(41b1)가 제1접속부재(31)의 걸림턱(31c1)으로 충분히 돌출되지 않으면, 단전이 필요한 상황에서 제1,2접속부재(31,32)가 접속이 이루어질 가능성이 있다.On the other hand, when the first fixing member 41 is operated due to a strong earthquake, the first fixing member 41 should operate as shown in FIG. 12 if it is normal, but the problem of the first fixing member 41 16, if the engaging portion 41b1 of the first fixing member 41 does not sufficiently protrude into the engaging step 31c1 of the first connecting member 31, There is a possibility that the connection members 31 and 32 are connected.

따라서, 관리자가 강한 지진이 발생한 후 다수의 지중배전선 지지 트레이기구를 점검할 시, 육안 또는 별도의 측정기로 제1고정부재(41)의 표식판(41e)과 제1고정부재(41)의 마개(41a)의 이격 거리를 확인하여, 제1고정부재(41)의 표식판(41e)과 제1고정부재(41)의 마개(41a)의 이격 거리가 미리 설정한 기준 값 보다 크면, 도 17에 도시된 바와 같이 제1고정부재(41)의 볼트바(41d)를 상방으로 이동시킨다.Therefore, when a manager checks a plurality of underground distribution line supporting tray mechanisms after a strong earthquake has occurred, the markers 41e of the first fixing members 41 and the stoppers 41b of the first fixing members 41, If the separation distance between the marking plate 41e of the first fixing member 41 and the stopper 41a of the first fixing member 41 is larger than a preset reference value, The bolt bar 41d of the first fixing member 41 is moved upward as shown in Fig.

그러면, 관리자가 다수의 지중배전선 지지 트레이기구를 점검하는 도중에 제1고정부재(41)의 걸림체(41b)에 따른 걸림력 약화로 도 18에 도시된 바와 같이 제1접속부재(31)가 좌방으로 이동할 시, 제1고정부재(41)의 볼트바(41d)가 제1접속부재(31)의 이동을 제한하여, 관리자가 다수의 지중배전선 지지 트레이기구 점검을 완료하고 보수 작업을 끝낼 때까지 제1,2접속부재(31,32)의 접속을 안정적으로 차단할 수 있다. 18, the first connecting member 31 is moved in the left-and-right direction as shown in FIG. 18 by the weakening of the hooking force of the first fixing member 41 along the stopping member 41b during the inspection of the plurality of underground distribution- The bolt bar 41d of the first fixing member 41 restricts the movement of the first connecting member 31 until the manager completes the inspection of the plurality of underground distribution supporting track apparatuses and finishes the maintenance work The connection of the first and second connecting members 31 and 32 can be stably prevented.

또한, 도 6에 도시된 바와 같이 제1고정부재(41)가 설치된 상태에서, 제1고정부재(41)의 노후화 정도를 점검하기 위하여, 제1고정부재(41)를 제1절연부재(21)로부터 분리하여 점검할 필요가 있다.6, in order to check the degree of deterioration of the first fixing member 41 in a state where the first fixing member 41 is installed, the first fixing member 41 is fixed to the first insulating member 21 It is necessary to separate them from each other and check them.

이때, 관리자는 제1고정부재(41)의 표식판(41e)를 하방으로 이동시키고, 제1고정부재(41)의 마개(41a)를 회전시켜 도 19에 도시된 바와 같이 제1고정부재(41)의 마개(41a)를 하방으로 이동시킨다. At this time, the manager moves the index plate 41e of the first fixing member 41 downward and rotates the stopper 41a of the first fixing member 41 to rotate the first fixing member 41 41 are moved downward.

여기서, 제1고정부재(41)의 스프링(41c)은 제1고정부재(41)의 마개(41a)에 안착되어 있기 때문에, 제1고정부재(41)의 마개(41a)가 회전하더라도 제1고정부재(41)의 마개(41a)를 따라 회전하지 않는다.Since the spring 41c of the first fixing member 41 is seated in the stopper 41a of the first fixing member 41, even if the stopper 41a of the first fixing member 41 rotates, And does not rotate along the stopper 41a of the fixing member 41. [

이때, 제1고정부재(41)의 마개(41a)를 제1절연부재(21)로부터 급하게 분리하면, 제1고정부재(41)의 스프링(41c)의 탄성력에 의해 순간적으로 제1고정부재(41)의 마개(41a)가 도 20에 도시된 바와 같이 하방으로 튈 수 있지만, 본 발명에서는 제1고정부재(41)의 표식판(41e)이 제1고정부재(41a)의 마개(41a)의 이탈을 막아, 제1고정부재(41)를 보다 안정적으로 제1절연부재(21)로부터 분리할 수 있다. At this time, if the cap 41a of the first fixing member 41 is suddenly separated from the first insulating member 21, the elastic force of the spring 41c of the first fixing member 41 instantaneously causes the first fixing member 41 20, the marking plate 41e of the first fixing member 41 may be detached from the stopper 41a of the first fixing member 41a in the present invention, It is possible to separate the first fixing member 41 from the first insulating member 21 more stably.

상술한 바와 같은 본 발명은 맨홀(MH) 내부 하측에 구조물을 설치하지 않음으로써 맨홀의 공간 활용도가 우수한 이점이 있다.The present invention as described above is advantageous in that the manhole (MH) is not provided with a structure under the inside thereof, and therefore the space utilization of the manhole is excellent.

또한, 본 발명은 작업자가 휴대용 조명기구를 소지하지 않더라도 맨홀(MH) 내부를 조명할 수 있어, 맨홀(MH) 내부에서의 지중배전선 수리작업이 편리한 이점이 있다.Further, the present invention is advantageous in that it is possible to illuminate the interior of the manhole (MH), even if the operator does not have a portable lighting fixture, and to easily repair the underground distribution line inside the manhole MH.

또한, 본 발명은 약한 지진이 발생할 경우에는 제1,2접속부재(31,32)의 접속을 유지하고, 강한 지진이 발생할 경우에는 제1,2접속부재(31,32)의 접속을 차단하여, 지진의 강도에 따라 적절하게 배전 및 단전이 이루어지도록 할 수 있는 이점이 있다.Further, the present invention maintains the connection of the first and second connecting members (31, 32) when a weak earthquake occurs and cuts off the connection of the first and second connecting members (31, 32) , There is an advantage that distribution and disconnection can be appropriately performed according to the strength of the earthquake.

또한, 본 발명은 제1,2고정부재(41,42)의 표식판(41e,42e)의 위치 변화를 통해 제1,2고정부재(41,42)의 스프링(41c,42c)의 탄성력 문제 발생을 확인할 수 있고, 상기 탄성력 문제 발생을 확인하면 제1,2고정부재(41,42)의 마개(41a,42a)를 상방으로 이동시켜, 제1,2고정부재(41,42)의 스프링(41c,42c)의 탄성력을 임시 보완한 후, 문제가 있는 제1,2고정부재(41,42)의 스프링(41c,42c)를 새로운 스프링(41c,42c)로 교체할 수 있다. 따라서 본 발명은 제1,2고정부재(41,42)의 문제 발생에 효과적으로 대처할 수 있는 이점이 있다.The elastic force of the springs 41c and 42c of the first and second fixing members 41 and 42 is changed by changing the position of the markers 41e and 42e of the first and second fixing members 41 and 42 When the occurrence of the elastic force problem is confirmed, the stoppers 41a and 42a of the first and second fixing members 41 and 42 are moved upward so that the spring of the first and second fixing members 41 and 42 The spring members 41c and 42c of the first and second fixing members 41 and 42 having problems may be replaced with new springs 41c and 42c after provisionally compensating the elastic forces of the first and second fastening members 41c and 42c. Therefore, the present invention has an advantage that it can effectively cope with the occurrence of the problems of the first and second fixing members 41 and 42. [

또한, 본 발명은 제1,2고정부재(41,42)에 문제가 발생하여, 제1,2고정부재(41,42)의 걸림체(41b,42b)가 효과적으로 제1,2접속부재(31,32)의 이동을 제한하지 못할 상황이 발생할 경우, 제1,2고정부재(41,42)의 볼트바(41d,42d)의 이동을 통해 제1,2접속부재(31,32)의 이동을 제한할 수 있어 보다 안정적으로 단전을 이룰 수 있는 이점이 있다. The present invention is also advantageous in that the first and second fastening members 41 and 42 have a problem that the fastening members 41b and 42b of the first and second fastening members 41 and 42 are effectively connected to the first and second connecting members 32b of the first and second fixing members 41 and 42 through movement of the bolt bars 41d and 42d of the first and second fixing members 41 and 42, The movement can be restricted, and there is an advantage that it is possible to achieve a more stable downturn.

또한, 본 발명은 제1,2고정부재(41,42)의 노후화를 확인하기 위해 제1,2절연부재(21,22)로부터 제1,2고정부재(41,42)를 분리할 시, 제1,2고정부재(41,42)의 스프링(41c,42c)의 탄성력에 의해 제1,2고정부재(41,42)의 마개(41a,42a)가 튀어 관리자에게 상해를 입힐 수 있지만, 본 발명에서는 제1,2고정부재(41,42)의 볼트바(41d,42d) 및 제1,2고정부재(41,42)의 표식판(41e,42e)를 통해 제1,2고정부재(41,42)의 마개(41a,42a)가 관리자를 향해 튀는 것을 차단할 수 있어, 관리자가 상해를 입는 것을 방지할 수 있는 이점이 있다. When the first and second fixing members 41 and 42 are separated from the first and second insulating members 21 and 22 to confirm the deterioration of the first and second fixing members 41 and 42, The stoppers 41a and 42a of the first and second fixing members 41 and 42 are projected by the elastic force of the springs 41c and 42c of the first and second fixing members 41 and 42, The bolts 41d and 42d of the first and second fixing members 41 and 42 and the markers 41e and 42e of the first and second fixing members 41 and 42, It is possible to prevent the stoppers 41a and 42a of the shutters 41 and 42 from splashing toward the manager, thereby preventing the administrator from being injured.

한편, 본 발명은 지중배전선(L)을 지지하는 트레기 기구 기능을 하는 제1,2안착기구(50,60)에 조명기구(10), 커버기구(20), 커넥팅기구(30), 고정기구(40)를 더 포함한다는 의미에서, 본 발명의 청구대상 및 발명의 명칭을 지중배전선 지지 트레이기구로 정의한다.
