특히 옥외에 설치된 경우에는 각종 이물질이나 자외선 등에 의해 손상이 쉽게 발생함은 물론 그만큼 수명이 단축되는 문제점이 있다. Particularly, when it is installed outdoors, damage is easily caused by various foreign substances and ultraviolet rays, and the lifetime is shortened accordingly.

또한, 리크감지센서의 교체시에는 바닥에 부착된 센서를 모두 제거하여야 하므로, 교체가 매우 번거로우며, 아울러 이로인한 비용적인 부담이 매우 크게 된다.In addition, when the leak detection sensor is replaced, all the sensors attached to the bottom must be removed, so that the replacement is very troublesome and the cost burden is very large.

그리고, 누설된 용액이 센서의 상부면에서 결빙되는 경우에는 센싱의 감도가 저하되어 센서의 신뢰성이 매우 저하되는 문제점이 있다. If the leaked solution is frozen on the upper surface of the sensor, the sensitivity of the sensing is lowered, and the reliability of the sensor is greatly reduced.

이와 같이 구성된 본 발명을 첨부한 도면을 참조하여 상세히 설명한다.The present invention thus constructed will be described in detail with reference to the accompanying drawings.

도1은 본 발명에 의한 리크감지센서용 케이스의 분해도이고, 도2는 결합 단면도로서, 크게 하부커버(100)와 상부커버(300)로 구성된다.FIG. 1 is an exploded view of a case for a leak detection sensor according to the present invention, and FIG. 2 is an assembled cross-sectional view, which comprises a lower cover 100 and an upper cover 300.

하부커버(100)는 직사각형의 함체 형태로 본체(110)가 구성되고, 그 본체(110)의 상부는 개방되며, 바닥부의 가운데 부분에는 리크감지센서(200)를 수납하여 장착하기 위한 센서장착홈(120)이 형성되어 있다.The lower cover 100 includes a main body 110 having a rectangular shape and an upper portion of the main body 110 is opened and a sensor mounting groove for accommodating and mounting the leak detecting sensor 200 is formed at the center of the bottom portion. (Not shown).

상기 센서장착홈(120)의 바닥부위 양측에는 발열전원을 공급하기 위한 각각 전극(161,162)이 구비되어 있다.Electrodes 161 and 162 are provided on both sides of the bottom of the sensor mounting groove 120 to supply heating power.

또한, 바닥부위의 가장자리 둘레로는 상부커버(300)와의 나사 체결을 위한 복수의 하부체결부(140)가 형성되어 있으며, 바닥부위에는 복수의 배수구(130)가 형성됨과 아울러 본체(110)의 외측에는 바닥에 볼트로 고정시키기 위한 고정부(150)가 형성되어 있다.A plurality of lower coupling parts 140 for screwing the upper cover 300 are formed around the edge of the bottom part and a plurality of drain holes 130 are formed at the bottom part, And a fixing part 150 is formed on the outer side to fix it to the floor with a bolt.

상기 센서장착홈(120)에 장착되는 리크감지센서(200)는 절연성을 갖는 아크릴, PC 등의 합성수지재로 플레이트(210)가 형성되는데, 이러한 플레이트(210)는 상기 센서장착홈(120)에 삽입되어 장착되었을 때 움직이지 않도록 센서장착홈(120)과 거의 동일한 크기를 가지며, 그 두께 또한 센서장착홈(120)의 높이와 동일하게 형성되는 것이 바람직하다.The leakage detection sensor 200 mounted on the sensor mounting groove 120 is formed of synthetic resin such as acrylic or PC having insulating properties and the plate 210 is inserted into the sensor mounting groove 120 It is preferable that the sensor mounting groove 120 has substantially the same size as the sensor mounting groove 120 so that the sensor mounting groove 120 does not move when it is inserted and mounted.

플레이트(210)의 상부면에는 길이방향으로 감지라인(220)이 형성되는데, 이러한 감지라인(220)은 물, 산이나 알칼리 등의 화학용액, 유기용제, 휘발유, 경유, 등유, 솔벤트, 각종 오일에 반응하여 저항값이 변화되는 물질로 형성된다.On the upper surface of the plate 210, a sensing line 220 is formed in the longitudinal direction. The sensing line 220 is formed of a chemical solution such as water, acid or alkali, an organic solvent, gasoline, diesel, kerosene, The resistance value of which is changed in response to the change of the resistance value.

또한, 플레이트(210)의 하부면에는 감지라인(220)과 동일한 위치에 카본, 카본, 블랙, 카본, 그래핀 등의 저항성을 갖는 소재에 의해 인쇄된 발열라인(230)이 형성되어 있다.A heating line 230 printed with a resistive material such as carbon, carbon, black, carbon or graphen is formed on the lower surface of the plate 210 at the same position as the sensing line 220.

이때 발열라인(230)은 감지라인(220)의 폭과 동일하거나 넓게 형성된다.At this time, the heating line 230 is formed to be equal to or wider than the width of the sensing line 220.

그러므로, 발열라인(230)은 센서장착홈(120)의 바닥부위에 형성된 전극(161,162)에 접촉되어 발열전원을 공급받음으로써 발열하게 되는 것이다. Therefore, the heating line 230 is brought into contact with the electrodes 161 and 162 formed at the bottom of the sensor mounting groove 120, and is heated by receiving the heating power.

상부커버(300)는 상기 하부커버(100)의 상측을 덮는 크기로 본체(310)가 형성되며, 본체(310)의 가운데 부분에는 상기 센서장착홈(120)에 장착된 리크감지센서(200)를 상측으로 노출시킴과 아울러 누설된 리크를 유입받기 위한 유입공(320)이 형성되어 있다.The upper cover 300 includes a main body 310 formed to cover the upper side of the lower cover 100 and a leak detecting sensor 200 mounted on the sensor mounting groove 120 at a central portion of the main body 310. [ And an inflow hole 320 for receiving leaked leaks.

또한, 그 상부면에는 리크를 유입공(320) 쪽으로 안내하기 위하여 유입공(320)쪽으로 경사진 경사부(330)가 형성되어 있으며, 하부체결부(140)와 동일한 위치에는 구멍 형태의 상부체결부(340)가 형성되어 있어서, 체결나사(30)에 의해 상부커버(300)가 하부커버(100)에 결합되는 것이다.An inclined portion 330 inclined toward the inflow hole 320 is formed on the upper surface thereof so as to guide the leakage toward the inflow hole 320. An upper inclined portion 330 is formed at the same position as the lower engaging portion 140, And the upper cover 300 is coupled to the lower cover 100 by the fastening screw 30.

상부커버(300)의 내측에는 도2에서와 같이 상기 리크감지센서(200)의 감지라인(220)의 양측에 각각 접촉되기 위한 동일한 구조의 단자부(380,390)가 설치되는데, 설명의 편의성을 위하여 단자부(380)의 구조에 대하여 설명한다.Terminal portions 380 and 390 having the same structure for contacting the both sides of the sensing line 220 of the leak sensing sensor 200 are installed on the inner side of the upper cover 300. For convenience of explanation, A description will be given of the structure of the optical disk 380 shown in FIG.

단자부(380)는 상부커버(300)의 내부 상측으로부터 하측으로 통체 형태로 연장된 격리벽체(381)가 형성되는데, 이러한 격리벽체(381)는 사각의 통체 형태를 갖는다.The terminal portion 380 is formed with an isolation wall 381 extending in a cylindrical form from the upper side to the lower side of the upper cover 300, and this isolation wall 381 has a rectangular tubular shape.

격리벽체(381)의 하단은 센서장착홈(120)에 장착된 리크감지센서(200)의 상부면에 근접하게 위치하고, 그 하단둘레로는 O-링(382)이 장착되며, 격리벽체(381)의 내측에는 포고핀(383)이 지지부(384)에 의해 지지되어 직립된 상태로 구비된다.The lower end of the isolation wall 381 is located close to the upper surface of the leak detection sensor 200 mounted on the sensor mounting groove 120 and the O-ring 382 is mounted around the lower end thereof. The pogo pin 383 is supported by the support portion 384 and is upright.

상기 포고핀(383)의 하단은 도3에서와 같이 리크감지센서(200)의 감지라인(210)의 일측에 탄성을 가지고 접촉되고, 감지라인(210)의 타측에는 단자부(390)의 포고핀(393)이 탄성을 가지고 접촉된다.3, the lower end of the pogo pin 383 is elastically contacted to one side of the sensing line 210 of the leak sensing sensor 200 and the other end of the sensing line 210 is connected to the pogo pin 380 of the terminal portion 390. [ (393) are brought into contact with elasticity.

이때, O-링(382,392)에 의해서 포고핀(383,393)이 상호간 격리됨으로써 방수가 이루어지는 것이다.At this time, the pogo pins 383 and 393 are separated from each other by the O-rings 382 and 392 to be waterproofed.

상기 포고핀(383,393)은 상부커버(300)의 내측에서 각각 배선(371,372)에 전기적으로 연결되고, 이러한 배선(371,372)은 상부커버(300)의 외측으로 연장되어 케이블(370) 형태로 알람모듈에 연결되는 것이다.The pogo pins 383 and 393 are electrically connected to the wirings 371 and 372 on the inner side of the upper cover 300. The wirings 371 and 372 extend outside the upper cover 300 to form an alarm module .

따라서 리크(L)가 발생하면, 유입공(320)을 통해 유입되어 리크감지센서(200)의 상부면으로 적하되며, 이로인해 감지라인(220)의 저항값이 변화되고, 이러한 저항값의 변화는 감지라인(220)의 양측에 접촉된 포고핀(383,393)에 의해 획득되어 배선(371,372)과 케이블(370)로 알람모듈에 제공되는 것이다.Therefore, when a leak (L) occurs, it flows through the inflow hole 320 and drops onto the upper surface of the leak detection sensor 200, thereby changing the resistance value of the sensing line 220, Are obtained by pogo pins 383 and 393 in contact with both sides of the sensing line 220 and are provided to the alarm module via wires 371 and 372 and cable 370.

또한, 하부커버(100)의 내측으로 유입된 리크(L)는 배수구(130)를 통해 외측으로 배수된다.Also, the leakage L introduced into the inside of the lower cover 100 is drained to the outside through the drain hole 130.

물론, 바닥으로 누설된 리크(L)의 경우에도 배수구(130)를 통해 유입되어 감지가 가능하게 된다.Of course, the leakage L leaked to the floor can also flow through the drain 130 and be sensed.

그리고, 상기 상부커버(300)의 유입공(320)에는 다수의 유입홀(361)을 갖는 커버부(360)가 장착되는데, 이러한 커버부(360)에 의해 낙엽 등의 이물질이 유입되어 감지라인(220)을 막는 것을 방지함은 물론 옥외에 설치되었을 때 자외선 등으로부터 감지라인(220)이 손상되는 것을 방지하게 된다.A cover part 360 having a plurality of inflow holes 361 is mounted on the inflow hole 320 of the upper cover 300. Foreign matter such as fallen leaves is introduced by the cover part 360, And prevents the sensing line 220 from being damaged from ultraviolet rays or the like when it is installed outdoors.

또한, 발열라인(230)에 의해 발생된 열은 리크감지센서(200)의 상부면으로부 전달되어 누설된 용액의 결빙이 방지되는 것이다.In addition, the heat generated by the heating line 230 is transferred to the upper surface of the leak sensor 200 to prevent freezing of the leaked solution.

아울러 리크(L)가 발생하여 리크감지센서(200)가 오염된 경우에는 이를 교체하여야 하는데, 이 경우 상부커버(300)를 열고, 오염된 리크감지센서(200)를 제거한 다음 새로운 리크감지센서를 센서장착홈(120)에 삽입하여 장착한 후에 상부커버(300)를 닫으면 된다.In this case, the upper cover 300 is opened, the contaminated leak sensor 200 is removed, and a new leak sensor 200 is opened. And the upper cover 300 may be closed after being inserted into the sensor mounting groove 120.

따라서, 리크감지센서(200)의 교체가 매우 쉬워 유지보수가 쉽게되는 것이다.Therefore, replacement of the leak detection sensor 200 is very easy and maintenance is easy.
