Description

질식소화를 이용한 소화커버모듈Extinguishing cover module using suffocation
본 발명은 질식소화를 이용한 소화커버모듈에 관한 것으로서, 보다 상세하게는 케이블이 연결된 접속부를 감싸며 보호함과 동시에 화재발생 시 외부공기유입을 차단하여 소화가 가능한 질식소화를 이용한 소화커버모듈에 관한 것이다.The present invention relates to a fire extinguishing cover module using suffocation fire extinguishing, and more particularly, to a fire extinguishing cover module using suffocation fire extinguishing capable of enclosing and protecting a connection to which a cable is connected and at the same time blocking external air inflow in the event of a fire to extinguish the fire. .
공공건물이나 사무실, 공장 등에서 사용하는 각종 전기 및 전자 제품은 전력을 공급받기 위하여 건물에 설치되는 케이블은 길이의 한계 또는 설치장소의 제한으로 인해 복수 개의 케이블을 연결하는 것이 필수적이다.Various electrical and electronic products used in public buildings, offices, factories, etc. are essential to connect a plurality of cables due to limitations in length or installation location of cables installed in buildings to receive power.
특히, 대형 건물이나 고층건물의 경우 많은 양의 전기 및 전자기기를 사용할 뿐만 아니라, 이에 따라 필요한 케이블의 길이 역시 늘어나기 때문에, 기성 제품의 케이블로는 길이의 한계가 있어 이들의 연결을 통해 문제의 해결이 필요하다.In particular, in the case of large buildings or high-rise buildings, not only do they use a large amount of electrical and electronic devices, but also the length of the necessary cables increases accordingly. A solution is needed.
하지만, 이러한 케이블의 경우 피복으로 코팅된 부분과 달리 케이블의 연결부는 전기적으로 불안정하며, 외부의 요인으로 인해 파손되거나, 저항으로 인한 온도상승에 의해 화재가 발생하는 문제가 있다.However, in the case of such a cable, unlike the coated portion, the connection portion of the cable is electrically unstable, and there is a problem that it is damaged due to external factors or a fire occurs due to a temperature increase due to resistance.
특히, 케이블의 접속부는 이러한 화재발생이나 외부에서 작용하는 외력으로부터 보호를 위한 접속키트와 수축튜브, 보호커버 등을 사용하여 왔으나, 내부적인 합선이나 누수로 인해 화재가 발생하는 것을 억제하기에는 문제가 있었다.In particular, connection kits, shrink tubes, protective covers, etc. have been used to protect the cable connection from such fires or external forces, but there is a problem in suppressing fires due to internal short circuits or water leaks. .
또한, 케이블의 접속부는 이미 외부와 한번 노출된 상태에서 결합된 부분으로 먼지와 습기 등에 취약하며, 보호커버의 장착으로도 공기의 노출로 인한 훼손이 발생한다.In addition, the connection part of the cable is a part that has been already exposed to the outside and is coupled, and is vulnerable to dust and moisture, and damage occurs due to exposure to air even when the protective cover is attached.
뿐만 아니라 화재의 경우 자주 발생하는 것이 아니지만, 한번만 발생하더라도 돌이킬 수 없는 피해를 입힐 수 있기 때문에 케이블에서 화재가 발생하는 경우 빠른 소화가 가능함과 동시에 케이블의 보호가 가능한 기술이 필요하다.In addition, fire does not occur frequently, but even if it occurs only once, it can cause irreversible damage. Therefore, if a fire occurs in a cable, a technology that can quickly extinguish it and protect the cable is required.

In addition, the connection part 20 of the cable 10 is in a relatively electrically unstable state, heat generation due to resistance increases, the risk of fire increases, and damage may occur due to external contact.
따라서, 이러한 케이블(10) 접속부(20)에는 접속부(20)의 보호와 함께 화재 발생 시 이를 사전에 차단하기 위한 소화커버모듈이 적용된다.Therefore, a fire extinguishing cover module is applied to the connection part 20 of the cable 10 to protect the connection part 20 and block it in advance in the event of a fire.
본 발명에 따른 질식소화를 이용한 소화커버모듈은 상기 케이블(10)을 감싸는 형태로 형성되어 내부의 수용공간(130)에 상기 접속부(20)가 위치하도록 하며 외부와 차단하는 형태로 구성된다. 크게 커버유닛(100), 소화유닛(200) 및 난연유닛을 포함한다.The fire extinguishing cover module using suffocation fire extinguishing according to the present invention is formed in a form surrounding the cable 10 so that the connection part 20 is located in the internal accommodation space 130 and is configured to block the outside. It largely includes a cover unit 100, a fire extinguishing unit 200 and a flame retardant unit.
상기 커버유닛(100)은 상기 케이블(10) 접속부(20)와 인접한 케이블(10)의 일부를 함께 감싸도록 구성되어 외력으로부터 상기 접속부(20)를 보호함과 동시에 접속부(20)에서 화재 발생 시 확산을 방지하도록 하는 구성으로, 기 설정된 길이를 가지며 내부에 수용공간(130)을 형성한다.The cover unit 100 is configured to cover a part of the cable 10 adjacent to the connection part 20 of the cable 10 together to protect the connection part 20 from external force and at the same time in case of fire in the connection part 20 With a configuration to prevent diffusion, it has a preset length and forms an accommodation space 130 therein.
그리고 상기 수용공간(130)을 중심으로 길이방향에 따른 양단부가 개방되어 상기 케이블(10)이 관통하며 중앙부에 상기 접속부(20)가 위치한다.Both ends along the longitudinal direction are opened around the receiving space 130 so that the cable 10 passes through and the connection part 20 is located in the central portion.
구체적으로 상기 커버유닛(100) 별도의 접속키트에 의해 연결된 상기 케이블(10)의 접속부(20)를 내부에 수용하는 구성으로 길이방향을 따라 길게 원통형상을 가지며, 양단부의 둘레가 상대적으로 작게 형성되어 상기 케이블(10)의 일부를 감싸도록 구성된다.Specifically, the cover unit 100 has a configuration for accommodating the connection part 20 of the cable 10 connected by a separate connection kit inside, has a long cylindrical shape along the longitudinal direction, and has a relatively small circumference at both ends. It is configured to wrap a part of the cable 10.
본 발명에서 상기 커버유닛(100)은 크게 외형부(110) 및 차단부(120)를 포함하고, 상기 외형부(110)는 상기 수용공간(130)을 가지며 상기 접속부(20)보다 상대적으로 큰 내경을 가지도록 구성된다. 여기서, 상기 외형부(110)는 원통 형상을 가지며 내부의 상기 수용공간(130)에 상기 접속부(20)가 위치하도록 한다, 이때, 상기 외형부(110)는 내부면이 상기 접속부(20)와 기 설정된 간격만큼 이격되어 접촉하지 않은 상태를 유지하며, 이에 따라 상기 접속부(20)의 온도 변화가 발생하더라도 영향을 받지 않는다.In the present invention, the cover unit 100 largely includes an outer portion 110 and a blocking portion 120, and the outer portion 110 has the accommodation space 130 and is relatively larger than the connection portion 20. It is configured to have an inner diameter. Here, the outer portion 110 has a cylindrical shape and allows the connection part 20 to be located in the accommodation space 130 therein. It is spaced apart by a predetermined interval and maintains a non-contact state, and thus is not affected even if a temperature change of the connection part 20 occurs.
상기 외형부(110)는 탄성을 가지며 일정 수준의 경도를 가지며 내 외부의 단열 및 유체의 차단이 가능한 소재로써, 난연 및 절연이 가능한 것으로 구성되는 것이 바람직하고, 본 실시예에서는 고무 소재로 구성되어 내부에 상기 수용공간(130)을 형성한다. The external portion 110 is a material that has elasticity, has a certain level of hardness, and is capable of insulating the interior and exterior and blocking fluid, and is preferably made of a material capable of flame retardancy and insulation. The receiving space 130 is formed inside.
한편, 상기 차단부(120)는 상기 외형부(110)의 길이방향에 따른 양단부에 형성되어 상대적으로 작은 둘레를 가지며 상기 케이블(10)의 끝단부를 감싸도록 구성된다.Meanwhile, the blocking portion 120 is formed at both ends of the outer portion 110 in the longitudinal direction, has a relatively small circumference, and is configured to surround the end portion of the cable 10 .
구체적으로 상기 차단부(120)는 상기 외형부(110)의 길이방향을 따라 연속하여 형성되어, 상기 케이블(10)의 끝단부를 감싸며 상기 수용공간(130) 내부를 밀폐시키도록 구성된다. 여기서, 상기 차단부(120)는 내면의 둘레가 상기 케이블(10)의 외면 둘레보다 상대적으로 작거나 같도록 형성되어 탄성을 가지며 상기 케이블(10)을 감쌈으로써 상기 수용공간(130)을 밀폐한다. Specifically, the blocking portion 120 is continuously formed along the longitudinal direction of the outer portion 110 to surround the end of the cable 10 and to seal the inside of the receiving space 130 . Here, the blocking part 120 has an inner circumference relatively smaller than or equal to the outer circumference of the cable 10, has elasticity, and seals the accommodation space 130 by wrapping the cable 10. .
이때, 상기 차단부(120)는 상기 외형부(110)와 일체로 연결되는 것이 바람직하며 동일소재 또는 이종소재로 구성될 수 있다.At this time, it is preferable that the blocking part 120 is integrally connected to the external part 110 and may be made of the same material or different materials.
본 실시예에서 상기 차단부(120)는 상기 외형부(110)의 양단부에서 기 설정된 길이를 가지며 돌출 형성되어 상기 케이블(10)의 끝단부를 외부에서 감싸도록 구성된다. In this embodiment, the blocking part 120 has a predetermined length from both ends of the outer part 110 and is formed to protrude to surround the end of the cable 10 from the outside.
이와 같이 상기 커버유닛(100)은 상기 외형부(110)와 상기 차단부(120)를 포함하며 내부에 형성된 상기 수용공간(130)에 상기 접속부(20)를 수용함과 동시에 상기 케이블(10)의 일부를 감싸며 상기 수용공간(130)을 외부와 차단한다. In this way, the cover unit 100 includes the outer portion 110 and the blocking portion 120 and accommodates the connection portion 20 in the accommodation space 130 formed therein and at the same time blocks the cable 10. It surrounds a part of and blocks the receiving space 130 from the outside.
여기서, 상기 외형부(110)와 상기 차단부(120)는 각각 원통 또는 다각형태의 단면 형상을 가지며, 상기 차단부(120)는 상기 외형부(110)의 단면 중앙부에 위치하도록 배치된다. 이에 따라 상기 케이블(10)은 상기 차단부(120)에 의해 둘레가 감싸지도록 배치됨으로써 상기 접속부(20)가 상기 수용공간(130) 내부에서 중앙에 배치되며 상기 외형부(110)의 내면에 접촉하지 않고 일정 간격을 유지할 수 있다.Here, the outer portion 110 and the blocking portion 120 each have a cylindrical or polygonal cross-sectional shape, and the blocking portion 120 is disposed at a central portion of the cross-section of the outer portion 110 . Accordingly, the cable 10 is arranged so that the circumference is wrapped by the blocking part 120, so that the connection part 20 is disposed in the center inside the accommodation space 130 and contacts the inner surface of the outer part 110. You can keep a certain interval without doing it.
한편, 상기 소화유닛(200)은 상기 커버유닛(100) 내부에 구비되어 상기 수용공간(130)에서 상기 케이블(10)과 인접하게 배치되며 기 설정된 온도 이상 열이 가해지는 경우 소화물질이 상기 케이블(10)을 향해 공급되도록 구성된다.On the other hand, the fire extinguishing unit 200 is provided inside the cover unit 100 and is disposed adjacent to the cable 10 in the accommodation space 130, and when heat above a predetermined temperature is applied, an extinguishing material is applied to the cable It is configured to be supplied toward (10).
구체적으로 상기 소화유닛(200)은 상기 커버유닛(100) 내부에 도포되거나 시트 형태로 형성되며, 일면이 상기 케이블(10)의 접속부(20)를 향하도록 배치된다. 그리고 인접하게 배치된 상기 케이블(10)에서 화재가 발생되는 경우, 발생된 열에 의해 온도가 상승하여 상기 소화유닛(200)에 포함된 상기 소화물질이 외부로 노출되며 상기 케이블(10)로 전달된다.Specifically, the fire extinguishing unit 200 is coated on the inside of the cover unit 100 or formed in a sheet shape, and is disposed so that one side faces the connection part 20 of the cable 10. And when a fire breaks out in the cable 10 disposed adjacent to it, the temperature rises due to the generated heat, so that the extinguishing material contained in the fire extinguishing unit 200 is exposed to the outside and transferred to the cable 10. .
본 발명에 따른 상기 소화유닛(200)은 크게 소화부(210) 및 코팅부(220)를 포함한다. 상기 소화부(210)는 상기 소화물질을 감싸며 기 설정된 온도에서 열에 의해 용융되며 파손되도록 구성된 복수 개의 미세캡슐을 포함한다.The fire extinguishing unit 200 according to the present invention largely includes a fire extinguishing unit 210 and a coating unit 220. The extinguishing unit 210 includes a plurality of microcapsules configured to enclose the extinguishing material and melt and break by heat at a preset temperature.
구체적으로 상기 소화부(210)는 상기 미세캡슐에 의해 감싸지며 복수 개로 구성된 소화캡술(212) 및 상기 소화캡술(212)과 혼합되는 바인더(214)를 포함한다.Specifically, the digestive unit 210 includes a plurality of digestive capsules 212 surrounded by the microcapsules and a binder 214 mixed with the digestive capsules 212.
상기 소화캡술(212)은 미세캡슐 내부에 별도의 소화물질을 감싸는 형태로 형성되며, 상기 소화캡술(212)이 일정 수준 이상의 온도에서 파손됨에 따라 내부의 상기 소화물질이 외부로 노출된다. 이때, 상기 소화캡술(212) 내부에서 화재를 소화할 수 있는 상기 소화물질은 분말 형태의 물질이거나 또는 가스계 소화약제를 포함할 수 있다.The digestive capsule 212 is formed in the form of wrapping a separate extinguishing material inside the microcapsule, and as the digestive capsule 212 is broken at a temperature above a certain level, the extinguishing material inside is exposed to the outside. At this time, the extinguishing material capable of extinguishing the fire inside the extinguishing capsule 212 may include a powdered material or a gas-based fire extinguishing agent.
그리고 이와 같이 구성된 상기 소화캡술(212)은 상기 접속부(20)에서 화재가 발생되는 경우 상기 접속부(20)를 향해 상기 소화물질이 공급되며, 이에 따라 상기 소화부(210)에서 자체적으로 상기 접속부(20)의 화재가 발생하더라도 빠르게 소화할 수 있다.And the fire extinguishing capsul 212 configured as described above is supplied with the extinguishing material toward the connection part 20 when a fire occurs in the connection part 20, and accordingly, in the fire extinguishing part 210 itself, the connection part ( 20), even if a fire occurs, it can be quickly extinguished.
여기서, 상기 소화물질은 대기를 이루는 물질보다 상대적으로 무겁게 형성되고, 상기 소화부(210)는 상기 수용공간(130) 내부에서 상기 접속부(20)의 의 중력방향에 따른 상부에 배치되는 것이 바람직하다. 다만 본 실시예와 같이 커버유닛(100)이 원통 형상으로 형성되어 상하의 구분이 어려운 경우, 내면의 둘레를 따라 고르게 상기 소화부(210)가 배치된다.Here, the extinguishing material is formed to be relatively heavier than the material constituting the atmosphere, and the fire extinguishing unit 210 is preferably disposed in the upper portion of the connection unit 20 along the direction of gravity in the accommodation space 130. . However, when the cover unit 100 is formed in a cylindrical shape and it is difficult to distinguish between upper and lower parts as in the present embodiment, the fire extinguishing unit 210 is evenly disposed along the circumference of the inner surface.
한편, 상기 바인더(214)는 상기 소화캡술(212)을 포함한 상태로 외형을 이루며 상기 수용공간(130) 내부에 구비될 수 있도록 하는 소재로써 상기 소화캡술(212)이 고르게 교반된 상태로 시트형태의 외형을 이루며 상기 수용공간(130) 내부에서 구비된다.On the other hand, the binder 214 is a material that forms an outer shape including the digestive capsule 212 and is provided inside the accommodation space 130, and is in the form of a sheet in a state in which the digestive capsule 212 is evenly stirred. It forms an external shape and is provided inside the receiving space 130.
구체적으로 상기 바인더(214) 상기 소화캡술(212)과 혼합된 상태로 일정 수준 이상의 두께를 가지며 시트형태로 상기 외형부(110)의 내면을 따라 결합되거나 도포된다. 여기서, 상기 바인더(214)는 열발포성 수지로 이루어지며, 소화부(210)에 열이 가해지는 경우 상기 바인더(214)가 연소 및 팽창함과 동시에 상기 소화캡술(212)이 터지며 소화물질이 하부방향으로 향하도록 구성된다Specifically, the binder 214 is mixed with the small capsul 212 and has a thickness of a certain level or more and is combined or applied along the inner surface of the outer portion 110 in a sheet form. Here, the binder 214 is made of a heat-expandable resin, and when heat is applied to the fire extinguishing unit 210, the binder 214 burns and expands, and the fire extinguishing capsule 212 bursts at the same time, and the extinguishing material configured to face the direction
이때, 상기 바인더(214)에 열이 가해지는 경우 팽창함으로써 상기 수용공간(130) 내부를 충진하고, 이에 따라 상기 접속부(20)가 외부공기와 접촉하는 것을 차단할 수 있다.At this time, when heat is applied to the binder 214, it expands to fill the inside of the accommodating space 130, and accordingly, it is possible to block contact of the connection part 20 with external air.
즉, 상기 바인더(214)는 열에 의해 팽창하여 상기 수용공간(130) 내부를 충진함과 동시에 내부에 수용된 상기 소화캡술(212)을 외부로 노출시켜 상기 소화물질이 상기 접속부(20)로 전달될 수 있도록 한다.That is, the binder 214 expands by heat to fill the inside of the accommodation space 130 and at the same time exposes the digestive capsule 212 accommodated therein to the outside so that the extinguishing material is delivered to the connection part 20. make it possible
이와 같이 상기 소화부(210)는 상기 수용공간(130) 내부에서 상기 접속부(20)를 향하도록 인접하게 배치되며, 열에 의해 상기 바인더(214)가 팽창해 상기 수용공간(130)을 충진하며 공기의 출입을 차단함과 동시에 상기 소화캡술(212)이 외부로 노출되어 상기 접속부(20)로 전달되도록 한다.In this way, the fire extinguishing unit 210 is disposed adjacent to the connection part 20 inside the accommodation space 130, and the binder 214 expands by heat to fill the accommodation space 130 and air. At the same time as blocking the entry and exit of the digestive capsul 212 is exposed to the outside so that it is transmitted to the connection portion (20).
본 실시예에서 상기 소화부(210)는 상기 외형부(110)의 내면에 구비되며, 추가적으로 상기 차단부(120)의 내면에도 함께 구비될 수도 있다. 특히, 상기 소화부(210)가 상기 차단부(120)의 내면에 구비된 상태에서 열을 전달받는 경우 상기 바인더(214)가 팽창하며 상기 케이블(10)을 압박함과 동시에 밀폐성능이 증가하여 상기 수용공간(130) 내부로의 공기 유입을 안정적으로 차단할 수 있다.In this embodiment, the fire extinguishing part 210 is provided on the inner surface of the outer part 110, and may additionally be provided on the inner surface of the blocking part 120 as well. In particular, when heat is transferred while the fire extinguishing unit 210 is provided on the inner surface of the blocking unit 120, the binder 214 expands and presses the cable 10 while sealing performance increases. The inflow of air into the receiving space 130 can be stably blocked.
한편, 상기 코팅부(220)는 상기 소화부(210)의 일면에 도포되어 상기 소화부(210)를 보호한다.Meanwhile, the coating unit 220 is applied to one surface of the fire extinguishing unit 210 to protect the fire extinguishing unit 210 .
구체적으로 상기 코팅부(220)는 상기 소화부(210)가 외부로부터 간섭에 의해 파손되거나, 의도하지 않는 상태에서 용융되는 것을 방지한다.Specifically, the coating part 220 prevents the fire extinguishing part 210 from being damaged by interference from the outside or being melted in an unintended state.
상기 코팅부(220)는 상기 소화부(210)의 일면에 형성되어 상기 소화부(210)를 보호하며, 상기 소화부(210)보다 상대적으로 높은 용도에서 용융되도록 구성된다.The coating unit 220 is formed on one surface of the fire extinguishing unit 210 to protect the fire extinguishing unit 210, and is configured to melt at a relatively higher use than the fire extinguishing unit 210.
즉, 상기 코팅부(220)는 상기 소화부(210)가 기 설정된 온도 이하에서 의도하지 않게 용융되는 것을 차단하며, 외력에 의해 손상되는 것을 방지하여 화재 발생시 정확하게 상기 소화부(210)가 동작할 수 있도록 한다.That is, the coating unit 220 prevents the fire extinguishing unit 210 from being unintentionally melted below a predetermined temperature, and prevents damage caused by an external force so that the fire extinguishing unit 210 can operate accurately when a fire occurs. make it possible
따라서 상기 수용공간(130) 내부에 안착된 상기 접속부(20)에서 화재가 발생하는 경우 상기 코팅부(220)가 먼저 용융되며, 상기 코팅부(220)가 용융된 후 자연스럽게 상기 소화부(210)가 용융 및 팽창되어 상기 소화캡술(212)이 상기 접속부(20)로 제공된다.Therefore, when a fire occurs in the connection part 20 seated inside the accommodation space 130, the coating part 220 is melted first, and after the coating part 220 is melted, the fire extinguishing part 210 naturally is melted and expanded so that the digestive capsul 212 is provided to the connection part 20.
이와 같이 상기 소화유닛(200)은 상기 코팅부(220) 및 상기 소화부(210)를 포함하며, 기 설정된 온도 이상으로 가열되는 경우 용융되어 상기 소화물질이 발화지점으로 전달되도록 한다. 이때 본 발명에 따른 상기 소화물질은 대기보다 무거운 비중을 가지며, 상기 소화캡술(212)이 파손되어 상기 소화물질이 외부로 노출되는 경우 자연스럽게 하부로 향하도록 구성된다.In this way, the fire extinguishing unit 200 includes the coating part 220 and the fire extinguishing part 210, and when heated to a predetermined temperature or higher, it is melted so that the extinguishing material is delivered to an ignition point.
