Description
본 고안은 화재가 발생하였을 때에 불연성 소화가스를 이용하여 화재를 진화하도록 하는 가스소화설비용 자동폐쇄장치에 관한 것이다.The present invention relates to an automatic closing device for a gas fire extinguishing system to extinguish a fire by using incombustible digestion gas when a fire occurs.
보다 상세하게는, 실내에 소화가스가 방출됨과 동시에 실내를 폐쇄시키도록 하는 자동폐쇄장치에 있어서, 구동수단에 의해 여러 개의 날개를 동시에 구동시켜 개폐를 실시하되, 날개는 스프링에 의해 탄발 장착한 것인바, 화재의 열에 의해 소화가스 및 실내 공기가 팽창하여 압력이 높아지면 탄발 장착한 날개는 스프링을 밀치고 개폐되어 소화가스를 배출시킴으로서 실내는 소정의 압력을 유지시킬 수 있도록 하여 화재 및 압력 등에 민감한 반응을 보이는 실험실 장비, 전산장비 및 방호구역 구조물 등을 보호할 수 있도록 하는 가스소화설비용 자동폐쇄장치를 제공하려는 것이다.More specifically, in the automatic closing device for closing the room at the same time as the exhaust gas is discharged to the room, the drive means to drive several wings at the same time to open and close, the blade is mounted by a spring by a spring When extinguishing gas and indoor air expand due to heat of Invar and fire, the bullet-mounted wing pushes the spring and opens and closes and releases extinguishing gas so that the room can maintain a predetermined pressure, so it is sensitive to fire and pressure. It is to provide an automatic shut-off device for gas fire extinguishing equipment to protect laboratory equipment, computer equipment and protective area structures.
옥내에서 화재가 발생하였을 때에 화재를 진화하기 위한 설비로서 물을 뿌리거나 소화가스를 분사하는 방식이 있다.When fire occurs indoors, it is a facility to extinguish a fire. There is a method of spraying water or extinguishing gas.
그러나 물을 뿌려서 진화하는 방식은 서류를 젖게 하거나, 전산장비는 더 이상 사용할 수 없도록 하기 때문에 중요시설이 있는 곳에는 소화가스를 사용하여 진화하는 가스소화설비를 갖추고 있다.However, water-fire extinguishing means wet paperwork, or computer equipment is no longer available, so there is a gas fire-extinguishing system that uses extinguishing gas where it is important.
예컨대, 전기실, 변전실, 발전실, 축전지실, 전산실, 통신기기실, 방재실, 제어실 등, 도서관, 박물관, 화랑 등, 인화성, 가연성 액체와 소화가스를 저장, 취급하는 장소, 기타 고가의 자산이 있는 장소에 설치된다.For example, electrical room, substation room, power generation room, battery room, computer room, communication equipment room, disaster prevention room, control room, library, museum, gallery, etc., store and handle flammable, flammable liquids and extinguishing gas, and other expensive assets. Is installed in place.
가스소화설비는 불연성 가스인 CO₂, Halon, 청정소화약제 등 소화가스를 고압가스용기에 저장하여 두었다가 화재가 발생하였을 때에 미리 설치된 소화설비에 의하여 화재 발생지역에 소화가스를 방출 분사시켜 질식 및 냉각작용에 의하여 소화를 목적으로 설치된 고정설비이다.Gas fire extinguishing facilities store extinguishing gases such as CO2, Halon, and clean extinguishing chemicals in a high pressure gas container. It is a fixed installation installed for the purpose of extinguishing.
이러한 가스계 소화약제는 약제방출시 외부의 신선한 공기가 유입되는 것을 차단하기 위하여 일반적으로 자동폐쇄장치를 설치하여 약제방출 직전이나 방출과 동시에 밀폐되는 구조를 가지고 있다.Such a gas-based extinguishing agent has a structure that is normally closed immediately before or during drug release by installing an automatic closing device in order to block the fresh air from flowing out during drug release.
일반적으로 대기 중에는 체적비로 산소가 21％를 차지하고 있으나 이를 약 15％ 이하로 감소시키면 연소가 계속적으로 되지못하고 소화되는 원리를 이용한 것이다.Generally, oxygen occupies 21% in the air by volume ratio, but if it is reduced to about 15% or less, combustion is not continued and the principle of extinguishing is used.
또한 불연성 가스에는 CO₂，Ｎ₂，Ar，프레온 등이 있으나 비교적 값이 저렴하고 기화 팽창률이 큰 액화 소화가스를 사용하고 있다.Non-combustible gases include CO₂, N₂, Ar, and Freon, but liquefied extinguishing gas, which is relatively inexpensive and has a high evaporation rate, is used.
즉 화재가 발생하였을 때에는 감지기가 화재를 감지하고 음향경보장치를 울림과 동시에 방화셔터 및 자동폐쇄장치(1)를 구동시키고, 아울러 소화가스를 분사헤드(2)를 통해 실내에 분사하게 된다.That is, when a fire occurs, the detector detects the fire, sounds the alarm system, and simultaneously drives the fire shutter and the automatic closing device 1, and injects the extinguishing gas into the room through the injection head 2.
소정의 압력이상으로 소화가스가 분사되었을 때에는 실내의 압력이 상승하고, 특히 화재의 열기에 의해 더욱 팽창하여 고가의 전산장비, 실험장비 및 방호구역 구조물 등 열기와 압력에 민감한 기기는 손상을 입히게 된다.When the extinguishing gas is injected above a certain pressure, the pressure inside the room rises, and in particular, it expands further by the heat of the fire, causing damage to heat and pressure sensitive devices such as expensive computer equipment, experimental equipment, and protective area structures. .
이러한 폐단을 예방하기 위하여, 실내의 벽 한쪽에 별도의 피압구(3)를 설치하여 소화가스 방출시 구동에 의해 실내압력을 소정의 압력이하로 조절하게 된다.In order to prevent such a closed end, a separate pressure port (3) is installed on one side of the wall of the room to adjust the room pressure to a predetermined pressure or less by driving when the extinguishing gas is released.
그러나, 상기와 같이 별도의 소화가스 피압구(3)를 설치하기 위해서는 벽에 시공하여야 하므로 시공이 매우 번잡스럽고 고가의 장비여서 가스소화설비를 갖추는 데는 많은 부담이 있었다.However, in order to install a separate extinguishing gas pressure port (3) as described above, because the construction is very complicated and expensive equipment was a lot of burden to equip the gas fire extinguishing equipment.
또한, 피압구(3)는 긴급 상황인 만큼 전자동으로 작동되어 야하지만 화재와 같은 재난은 예상하지 못한 상태에서 갑자기 일어나는 것으로 수시로 점검하여야 비상시에 제대로 작동할 수 있으므로 유지보수에 매우 높은 비용을 지출해야 하는 문제점이 있었다.In addition, the pressure port (3) should be operated automatically as it is an emergency, but the disaster such as fire suddenly occurs unexpectedly and must be checked from time to time so that it can work properly in an emergency. There was a problem.
본 고안은 상기와 같은 문제를 해소할 수 있도록 더욱 개선된 가스소화설비용 자동폐쇄장치를 제공하려는 것이다.The present invention is to provide a more improved automatic closing device for gas fire extinguishing equipment to solve the above problems.
본 고안은 몸체의 내부에 여러 개의 날개를 축에 굴대 장착하고, 구동수단에 의해 여러 개의 날개를 동시에 구동시켜 개폐를 실시하되, 날개는 스프링에 의해 탄발 설치하여 실내의 압력이 설정압력보다 상승할 때에는 그 실내 압력은 스프링을 밀치고 열리도록 하여 자동으로 소화가스를 배출시켜 소정의 압력을 유지시키도록 하는 가스소화설비용 자동폐쇄장치를 제공하는데 그 목적이 있다.The present invention is equipped with a plurality of wings on the shaft axle inside the body, and by driving the drive several wings at the same time to open and close, the blades are installed by a spring by the spring to increase the pressure in the room than the set pressure The purpose of the present invention is to provide an automatic closing device for a gas fire extinguishing system in which the indoor pressure pushes and opens the spring to automatically discharge the extinguishing gas to maintain a predetermined pressure.
본 고안의 다른 목적은 자동폐쇄장치의 날개가 스프링의 설정압력에 의해 기구적으로 작동하도록 함으로서 종래에서처럼 고가의 피압구 등을 설치하지 않고도 동일한 효과를 얻을 수 있도록 하는 가스소화설비용 자동폐쇄장치를 제공하는데 있다.Another object of the present invention is to provide an automatic closing device for a gas fire extinguishing system in which the wing of the automatic closing device is mechanically operated by the set pressure of the spring, so that the same effect can be obtained without installing an expensive pressure port or the like as conventionally. To provide.
본 고안의 상기 및 기타 목적과 특징은 첨부도면에 의거한 다음의 상세한 설명에 의하여 더욱 명확하게 이해 할 수 있을 것이다.The above and other objects and features of the present invention will be more clearly understood by the following detailed description based on the accompanying drawings.

도 2 내지 도 4에 도시한 바와 같이, 본 고안에 따른 가스소화설비용 자동폐쇄장치(1)는, 대략 사각 틀로 형성한 몸체(10)의 안쪽에 여러 개의 축(12)을 나란하게 등간격으로 장착하고, 축(12)에는 날개(13)(14)를 굴대 장착하며, 몸체(10)의 한 쪽에는 구동수단(11)을 장착한 것이다.As shown in Figures 2 to 4, the automatic closing device for gas fire extinguishing equipment 1 according to the present invention, a plurality of shafts 12 are arranged side by side at the inner side of the body 10 formed in a substantially rectangular frame side by side The shaft 12 is mounted to the mandrel wing 13, 14, and one side of the body 10 is equipped with a drive means (11).
상기 여러 개의 날개(13)(14)는 링크에 의해 연결되어 어느 하나의 날개를 열거나 닫으면 다른 모든 날개가 동시에 열리거나 닫히도록 된 것이다.The plurality of wings 13 and 14 are connected by a link so that when one wing is opened or closed, all other wings are opened or closed at the same time.
상기 구동수단(11)은 구동모터 또는 실린더 등을 장착할 수 있는 것이다.The drive means 11 is to be equipped with a drive motor or a cylinder.
상기 날개(14)는 스프링(15)에 의해 탄발 설치한 것으로 첨부도면 도 3 내지 도 5를 참조하여 설명한다.The wing 14 is installed by the spring 15, and will be described with reference to the accompanying drawings, FIGS.
날개(14)는 축(12)에 굴대 장착하되 코일스프링의 일종인 토션 스프링을 장착한 것으로 스프링(15)에 의해 날개(14)는 항상 닫히는 방향으로 힘을 받는 것이고, 스프링(15)의 탄성력보다 큰 압력이 날개(14)에 작용할 때에는 날개(14)가 스프링(15)을 밀치고 열리게 되는 것이다.The wing 14 is a mandrel mounted on the shaft 12, but is equipped with a torsion spring, a kind of coil spring. The wing 14 is always forced by the spring 15 in the closing direction, and the elastic force of the spring 15 is applied. When greater pressure acts on the blade 14, the blade 14 is pushed open the spring 15.
첨부도면 도 6은 본 고안에 따른 다른 날개(13a)의 다른 실시한 예를 보인 것으로 도시한 바와 같이 통상의 날개(13a)의 한쪽에 통기구멍(16)을 형성하고, 그 통기구멍(16)의 한쪽에 날개(14a)를 굴대 장착한 것이다.6 is a view showing another embodiment of another wing 13a according to the present invention, and a ventilation hole 16 is formed in one side of a conventional wing 13a, and the ventilation hole 16 is The blade 14a is mandrel mounted on one side.
특히 상기 날개(14a)는 스프링(15)에 의해 탄발 설치된 것으로 평소에는 스프링(15)에 의해 날개(14a)가 원래의 날개(13a)에 밀착되어 있는 것이다.In particular, the wing 14a is elastically installed by the spring 15, and the wing 14a is in close contact with the original wing 13a by the spring 15.
이하 작용을 첨부도면 참조하여 설명한다.Hereinafter, the operation will be described with reference to the accompanying drawings.
화재가 발생하지 않는 평상시에 자동폐쇄장치(1)는, 날개(13)를 개방된 상태를 유지하여 통상의 공기조화설비에 의해 실내 공기를 환기시키거나 실내 온도를 유지하게 된다.When the fire does not occur normally, the automatic closing device 1 maintains the wing 13 in an open state to ventilate the indoor air by a normal air conditioning system or maintain the room temperature.
화재가 발생하면 감지기는 화재를 감지하여 음향경보장치를 울림과 아울러 소화가스를 공급하여 분사헤드(2)를 통해 분사시키고, 또한 자동폐쇄장치(1)를 구동시켜 실내를 폐쇄시키는 것이다.When a fire occurs, the detector detects a fire, sounds an acoustic alarm device, supplies fire extinguishing gas, injects through the injection head 2, and also closes the room by driving the automatic closing device 1.
상기 자동폐쇄장치(1)는 구동수단(11)이 구동하여 날개(13)를 닫히는 방향으로 구동하고 소화가스는 실내에 채워진다.The automatic closing device 1 is driven in the direction in which the drive means 11 to close the wing 13 and the extinguishing gas is filled in the room.
실내에 채워진 소화가스는 화재의 열기에 의해 팽창하게 되는데, 이렇게 실내공기와 소화가스가 팽창하여 압력이 높아지면 이 압력은 날개(14)를 밀치고 개방되어 공기와 소화가스를 배출시키게 되고, 공기와 소화가스가 배출되어 압력이 낮아지면 스프링(15)의 복원력에 의해 닫히게 된다.The digested gas filled in the room is expanded by the heat of the fire. When the indoor air and the digested gas expand and the pressure increases, the pressure pushes the wings 14 and opens to release the air and the extinguishing gas. When the extinguishing gas is discharged and the pressure is lowered, it is closed by the restoring force of the spring 15.
또한 도 6에 도시한 다른 실시한 예에서는 자동폐쇄 장치(1)가 작동하여 날개(13a)가 닫혔을 때에 실내는 폐쇄되고 실내 압력이 높아지면 그 압력은 날개(14a)의 스프링(15) 힘을 이기고 밀어서 날개(14a)는 들춰져 유통구멍(16)은 열리면서 배기가 이루어지는 것이다.In addition, in another embodiment shown in FIG. 6, when the wing 13a is closed by the operation of the automatic closing device 1, the room is closed and the room pressure is increased, and the pressure is applied to the spring 15 force of the wing 14a. By winning and pushing, the wing 14a is lifted and the distribution hole 16 is opened, and exhaust is performed.
소화가스의 압력이 낮아지면 스프링(15)의 복원력에 의해 날개(14a)는 닫히고 다시 폐쇄구조를 유지하는 것이다.When the pressure of the extinguishing gas is lowered, the wing 14a is closed by the restoring force of the spring 15 and maintains the closed structure again.
따라서 소화가스에 의해 화재는 진화됨과 아울러 소정의 압력이상으로 상승하는 것을 예방함으로서 열기와 압력에 민감한 실험실 장비, 전산장비 및 방호구역 구조물 등을 보호하는 것이다.Therefore, the fire is extinguished by the extinguishing gas and protects laboratory equipment, computer equipment, and protective area structures sensitive to heat and pressure by preventing rising above a predetermined pressure.
본 고안은 기재된 구체적인 예에 대하여만 상세히 설명되었지만 본 고안의 기술사상범위 내에서 다양한 변형 및 수정이 가능함은 당업자에게 있어서 명백한 것이며, 이러한 변형 및 수정이 첨부된 실용신안등록청구범위에 속함은 당연한 것이다.Although the present invention has been described in detail only with respect to the specific examples described, it will be apparent to those skilled in the art that various changes and modifications are possible within the technical scope of the present invention, and such modifications and modifications belong to the appended utility model registration claims. .
본 고안에 따른 가스소화설비용 자동폐쇄장치의 구조는 날개(14)(14a)를 스프링(15)에 의해 탄발 설치함으로서 스프링(15)의 복원력에 의해 항상 닫히도록 하고 고압으로 압력이 상승하였을 때에는 그 압력은 스프링(15)을 밀치고 날개(14)(14a)가 개방되어 압력을 소화가스를 배기시킴으로서 실내의 압력이 소정의 압력보다 상승하는 것을 예방할 수 있는 것이다.The structure of the automatic closing device for the gas fire extinguishing system according to the present invention is to be always closed by the restoring force of the spring 15 by installing the wings 14, 14a by the spring 15, and when the pressure rises at a high pressure. The pressure pushes the spring 15 and opens the wings 14 and 14a to exhaust the extinguishing gas so that the pressure in the room can be prevented from rising above a predetermined pressure.
특히 압력이 고압으로 상승하는 것을 예방함으로서 열기와 압력에 민감한 실험장비 및 전산장비 및 방호구역 구조물 등을 보호할 수 있는 것이다.In particular, by preventing the pressure rise to high pressure it is possible to protect the experimental equipment, computer equipment and protection area structure sensitive to heat and pressure.
