Description

권취식 소방호스가 장착된 소화전{Fire hydrant with wind-up fire hose}Fire hydrant with wind-up fire hose}

본 발명은 권취식 소방호스가 장착된 소화전에 관한 것으로서, 더욱 더 상세하게는 겨울철과 같이 온도의 급격한 저하가 발생하는 경우에도 소화전함의 수용공간의 온도가 일정한 온도를 유지하면서 소방호스 내부에 남아있는 소화용수가 얼어붙지 않도록 하는 권취식 소방호스가 장착된 소화전에 관한 것이다.The present invention relates to a fire hydrant equipped with a wound fire hose, and more particularly, even when a sudden decrease in temperature occurs, such as in winter, the temperature of the receiving space of the hydrant box remains inside the fire hose while maintaining a constant temperature. It relates to a fire hydrant equipped with a wound fire hose that prevents the existing fire water from freezing.

일반적으로 옥내 소화전은 화재 초기에 소방대상물의 거주자가 소화전함에 비치되어 있는 소방호스 및 노즐을 이용하여 소화작업을 하는 설비이다.In general, an indoor fire hydrant is a facility in which a resident of a fire-fighting object performs fire extinguishing work using a fire hose and nozzle provided in a fire hydrant box at the beginning of a fire.

그 구조는 수원, 가압송수장치, 배관 그리고 개폐밸브, 호스, 노즐 등이 들어 있는 소화전함이 구성되어 있으며, 소화펌프 기동방식 스위치를 기동하여 사용할 수 있게 되어 있다.The structure consists of a water source, a pressurized water supply device, a piping, and a fire hydrant box containing an opening/closing valve, a hose, a nozzle, etc., and it can be used by starting a fire pump starting type switch.

그리고 상기의 옥내 소화전의 배치는 특정 소방대상물의 층마다 설치하되, 층의 각 부분으로부터 1개의 호스 접결구까지의 수평거리가 25m를 초과할 수 없다.In addition, the above indoor fire hydrants are arranged for each floor of a specific firefighting object, but the horizontal distance from each part of the floor to one hose joint cannot exceed 25m.

옥내 소화전 개폐밸브는 바닥으로부터 15m 이하인 곳에 설치하여야 한다.Indoor fire hydrant opening/closing valves should be installed 15m or less from the floor.

수원의 수량은 옥내 소화전의 설치개수(설치개수가 5개를 초과하는 경우에는 5개로 기준 한다.)가 가장 많은 층의 설치개수에 2.6㎥을 곱하여 얻은 값 이상이 되도록 하여야 한다.The number of water sources should be higher than the value obtained by multiplying the number of installations on the floor with the largest number of indoor fire hydrants installed (if the number of installations exceeds 5, it is standardized as 5) by 2.6㎥.

어느 층에서나 각 층의 모든 옥내 소화전을 동시에 사용하는 경우에는 각 노즐 끝의 방수압력이 17kg/㎠이고, 방수량이 130ℓ/min 이상이어야 한다.If all indoor fire hydrants of each floor are used at the same time on any floor, the waterproof pressure at the end of each nozzle must be 17kg/㎠ and the waterproof amount must be 130ℓ/min or more.

옥내 소화전에는 그 표면에 소화전함이라고 표시하고 상부에 표시등(적색등)을 설치하되, 그 불빛이 부착면과 15° 이하의 각도로 반사하여 10m 거리에서 쉽게 식별할 수 있어야 한다.For indoor fire hydrants, mark the surface as a fire hydrant and install an indicator (red light) on the top, but the light must be reflected at an angle of 15° or less from the mounting surface so that it can be easily identified from a distance of 10 m.

각 층에 전용배관을 설치하고, 가압송수장치의 분출면에서 가장 가까운 부분의 배관에 체크밸브를 설치한다.Dedicated pipes are installed on each floor, and check valves are installed in the pipes closest to the ejection surface of the pressurized water supply system.

펌프를 사용하는 가압송수장치의 흡수관에는 여과장치 및 수원의 수위가 펌프보다 낮은 위치에 있는 것에는 후드밸브, 기타의 것에는 스톱밸브를 설치한다.A hood valve is installed in the absorption pipe of the pressurized water supply system using a pump and a hood valve in the case where the water level of the water source is lower than that of the pump, and a stop valve in the other.

관은 내식성 및 내열성 관을 사용하며, 주배관 중 입상관은 50mm 이상의 것으로 하고, 연결송수관 설비의 배관과 겸용할 경우 배관은 구경 100mm 이상, 가지관은 65mm 이상의 것으로 해야한다.Corrosion-resistance and heat-resistance pipes are used for pipes. Among the main pipes, upright pipes should be 50mm or more, and when combined with the pipes of the connecting water supply pipes, the pipes should have a diameter of 100mm or more and branch pipes should be 65mm or more.

상기와 같이 이루어지는 종래의 옥내 소화전은 길이가 긴 소방호스를 포개어 접은 다음 소화전함에 설치한 걸이구에 걸려지도록 설치한다.In the conventional indoor fire hydrant made as described above, a long fire hose is stacked and folded, and then installed to be hooked on a hook installed in a fire hydrant box.

그러나 장시간 보관 중 접힌 부분에 곰팡이가 발생되어 위생적인 관리가 불가능할 뿐 아니라, 오랜 시간 보관하는 과정에서 접힌 부분이 삭아서 소방호스가 부분적으로 파절됨으로서, 신속한 화재 진압 작업이 곤란하였다.However, mold was generated on the folded part during long-term storage, making it impossible to hygienic management. Also, the fire hose partially fractured due to the collapse of the folded part during long-term storage, making it difficult to quickly extinguish the fire.

또한, 순차적으로 걸이구에 걸려진 소방호스는 소방호스 사용자에 의해 발화점으로 견인될 때에 소방호스가 비틀어지면서 견인되는 경우가 많았다.In addition, when the fire hoses sequentially hung on the hooks are towed to the ignition point by the fire hose user, the fire hose is twisted and towed in many cases.

비틀어진 호스는 소방용수 공급시에 높은 수압으로 인해 제자리로 복귀하는바, 이 과정에서 높은 수압으로 인해 관창이 회전되면서 소방호스 사용자의 손에서 이탈되어 타격하는 등의 인사사고가 발생하는 문제점이 있었다. The twisted hose returns to its original position due to high water pressure when supplying water for firefighting. In this process, there was a problem that personnel accidents such as being removed from the fire hose user's hand and hitting the pipe window rotated due to high water pressure. .

따라서 종래에도 상기와 같은 종래의 소화전함에 보관되는 소방호스의 문제점을 개선하기 위해 선행기술이 하기와 같이 개시되었다.Therefore, even in the prior art, in order to improve the problems of the fire hose stored in the conventional fire hydrant box as described above, the prior art has been disclosed as follows.

대한민국 등록특허공보 제10-1351939호(2014 0117 공고) "권취식 소방호스가 장착된 소화전함"은 인입소방호스의 일측은 방수배관에 접속되고, 인입소방호스의 타측은 보빈의 외판에 접속되며, 일측에 관창이 연결된 인출소방호스의 타측은 보빈에 접속되되, 상기 인출 소방호스의 타측이 접속되는 보빈의 외주면에는 인출접속단자가 접합되고, 보빈의 양측에 접합된 외판 중 소화전함의 전방에서 인식되는 외판에는 상기 인입소방호스가 접속되도록 인입접속단자가 접합되며, 상기 인출접속단자와 인입접속단자를 연결하는 플렉시블관은 보빈의 내부에 위치되고, 상기 외판과 보빈을 관통하여 설치되는 다단회전봉은 외판의 중앙에 형성된 구멍에 베어링과 함께 회동 가능하게 장착되며, 상기 외판중 소화전함의 전방에서 인식되는 외판의 편심된 일측에는 회동돌기가 형성되고, 상기 회동돌기에 끼워 보빈을 회전시킬 수 있는 레버가 구비되어, 소방호스가 보빈에서 신속하게 풀리고 감길수 있도록 한 것을 특징으로 하고 있다.Republic of Korea Patent Publication No. 10-1351939 (2014 0117 announcement) "Fire hydrant box equipped with a roll-up fire hose", one side of the incoming fire hose is connected to the waterproof pipe, and the other side of the incoming fire hose is connected to the outer plate of the bobbin. , The other side of the draw-out fire hose connected to one side is connected to the bobbin, and the draw-out connection terminal is bonded to the outer circumference of the bobbin to which the other side of the draw-out fire hose is connected, and from the front of the fire hydrant box among the outer plates bonded to both sides of the bobbin. A lead-in connection terminal is joined to the recognized outer plate so that the lead-in fire hose is connected, and a flexible pipe connecting the lead-out connection terminal and the lead-in connection terminal is located inside the bobbin, and a multi-stage rotating rod is installed through the outer plate and the bobbin. Is mounted rotatably together with a bearing in a hole formed in the center of the outer plate, and a pivoting protrusion is formed on one eccentric side of the outer plate recognized from the front of the fire hydrant among the outer plates, and can be inserted into the pivoting protrusion to rotate the bobbin. A lever is provided so that the fire hose can be quickly released and wound on the bobbin.

상기와 같이 구성되는 선행기술은 권취식 소방호스가 장착된 소화전함을 사용하게 되면, 촌각을 다투는 화재현장에서 신속하게 소방호스를 발화점으로 이동시킬 수 있으므로 소화(消火)능력이 향상되는 효과는 있으나, 화재를 진압한 후 소방호스를 보빈에 감을 때 소방호스 내측에 남아있는 소화용수가 제대로 배출되지 않아 겨울철에 소방호스가 동파되어 화재 진압이 어려운 문제점이 있었다. The prior art constructed as described above has the effect of improving the fire extinguishing ability because when using a fire hydrant box equipped with a wound fire hose, the fire hose can be quickly moved to the ignition point at the fire site that is struggling. However, when the fire hose was wound on the bobbin after extinguishing the fire, the fire fighting water remaining inside the fire hose was not properly discharged, causing the fire hose to freeze in winter, making it difficult to extinguish the fire.

대한민국 등록특허공보 제10-1351939호(2014. 01.17 공고)Republic of Korea Patent Publication No. 10-1351939 (announced on Jan. 17, 2014)

본 발명은 상기와 같은 종래의 문제점을 해결하기 위해 안출된 것으로서, 소방호스가 수용되는 본체의 수용공간의 온도를 겨울철과 같이 주변온도가 급격히 저하되는 경우에도 3℃ ~ 5℃의 온도가 유지되도록 함으로써, 상기 겨울철에 소방호스를 사용후 상기 소방호스의 내부에 소화용수가 남아있는 상태로 보빈에 감으면서 본체의 수용공간에 소방호스를 수납시키는 경우에도, 상기 소방호스의 내부에 남아있는 소화용수가 얼지 않도록 하는 권취식 소방호스가 장착된 소화전을 제공하는 데 있다. The present invention has been devised to solve the conventional problems as described above, so that the temperature of the receiving space of the main body in which the fire hose is accommodated is maintained at a temperature of 3°C to 5°C even when the ambient temperature is rapidly decreased, such as in winter. By doing so, even when the fire hose is stored in the receiving space of the main body while the fire hose is wrapped around the bobbin while the fire hose remains inside the fire hose after using the fire hose in winter, the water remaining inside the fire hose It is to provide a fire hydrant equipped with a wound fire hose to prevent freezing.

상기와 같은 목적을 달성하기 위한 본 발명은 전면이 개구된 수용공간(110)을 갖는 본체(100)와; 상기 본체(100)의 수용공간(110)에 회동가능하게 설치되는 보빈(200)과; 상기 보빈(200)이 설치된 본체(100)의 수용공간(110)을 개폐시키는 도어(120)와; 상기 보빈(200)에 감김 및 풀림 가능하게 설치되는 소방호스(300)와; 상기 소방호스(300)가 수용되어있는 수용공간(110)의 내부에 전원을 공급받으며 히팅이 이루어지도록 설치되는 히터(400)와; 상기 히터(400)가 설치된 수용공간(110)의 온도를 감지하는 감지센서(700)와; 상기 감지센서(700)에 의해 감지된 수용공간(110)의 온도가 7℃ 이하인 경우에는 수용공간의 온도가 3℃~ 5℃ 이하로 떨어지지 않도록 히터(400)로 전원이 공급되도록 신호를 출력하고, 상기 수용공간(110)의 온도가 7℃ 이상인 경우에는 히터(400)로 공급되는 전원이 차단되도록 신호를 출력하는 컨트롤러(500)로 구성되는 것에 의해 달성된다.The present invention for achieving the above object is a main body 100 having a receiving space 110 with an open front; A bobbin 200 rotatably installed in the receiving space 110 of the main body 100; A door 120 for opening and closing the accommodation space 110 of the main body 100 in which the bobbin 200 is installed; A fire hose 300 installed to be wound and unwound around the bobbin 200; A heater 400 installed so as to receive power and heat the inside of the receiving space 110 in which the fire hose 300 is accommodated; A detection sensor 700 for sensing the temperature of the accommodation space 110 in which the heater 400 is installed; When the temperature of the accommodation space 110 sensed by the detection sensor 700 is 7℃ or less, a signal is output so that power is supplied to the heater 400 so that the temperature of the accommodation space does not fall below 3℃-5℃. When the temperature of the receiving space 110 is 7° C. or higher, it is achieved by being configured with a controller 500 that outputs a signal so that power supplied to the heater 400 is cut off.

한편, 상기 컨트롤러(500)로 부터 출력되는 신호에 따라 히터(400)로 공급되는 전원은 트랜스(600)를 통해 AC 200V의 전원이 DC 24V로 전환된 상태에서 공급되어 지게 됨을 밝혀 둔다. On the other hand, it is revealed that the power supplied to the heater 400 according to the signal output from the controller 500 is supplied through the transformer 600 while the power of AC 200V is converted to DC 24V.

또한, 상기 트랜스(600)와 컨틀롤러(500) 및 히터(400)는 수용공간(110)의 일측부에 고정 설치되는 브라켓트(800)에 설치됨을 밝혀 둔다. In addition, it is revealed that the transformer 600, the controller 500, and the heater 400 are installed on a bracket 800 fixedly installed on one side of the receiving space 110.

본 발명에 따르면 소방호스가 수용되는 본체의 수용공간의 온도가 7℃ 이하인 경우에는 히터가 히팅이 이루어지면서 겨울철과 같이 주변온도가 급격히 저하되는 경우에도 본체의 수용공간 온도가 영상 3℃~ 5℃ 이하로 떨어지지 않게 됨으로써, 상기 수용공간에 보빈에 감기어진 상태로 보관중인 소방호스의 내부에 남아있는 소화용수가 겨울철과 같이 주변온도가 급격히 저하되는 경우에도 얼지 않아 상기 소방호스가 동파되지 않게 되는 효과가 있는 매우 융용한 발명이다. According to the present invention, when the temperature of the receiving space of the main body in which the fire hose is accommodated is 7°C or less, the temperature of the receiving space of the main body is 3°C to 5°C even when the ambient temperature is rapidly decreased as in winter as the heater is heated. By not falling below, the firefighting water remaining inside the fire hose that is stored in the state of being wound on the bobbin in the receiving space does not freeze even when the ambient temperature drops sharply such as in winter, and the fire hose does not freeze. It is a very fusion invention.

이와 같이 구성되는 본 발명은 평상시 보빈(200)에 감긴 상태로 소방호스(300)가 보관되고 있는 본체(100)의 수용공간(110)에 브라켓트(800)가 고정되게 설치되고, 상기 브라켓트(800)에는 AC 200V의 전원을 DC 24V로 변환시키는 트랜스(600)와, 상기 트랜스(600)에 의해 DC 24V로 변환된 전원을 공급받으며 히팅이 이루이지는 히터(400)와, 수용공간(110)의 온도를 감지하는 감지센서(700)와, 상기 감지센서(700)에 의해 감지된 수용공간(110)의 온도가 7℃ 이하인 경우에는 수용공간(110)의 온도가 3℃~ 5℃ 이하로 떨어지지 않도록 히터(400)로 전원이 공급되도록 신호를 출력하고, 상기 수용공간(110)의 온도가 7℃ 이상인 경우에는 히터(400)로 공급되는 전원이 차단되도록 신호를 출력하는 컨트롤러(500)와, 상기 컨트롤러(500)에 의해 출력되는 신호에 따라 전원 인가가 제한되는 트랜스(600)가 각각 설치된다. In the present invention configured as described above, the bracket 800 is fixedly installed in the receiving space 110 of the main body 100 in which the fire hose 300 is stored while the fire hose 300 is normally wound around the bobbin 200, and the bracket 800 ), a transformer 600 for converting the power of AC 200V to DC 24V, a heater 400 for heating while receiving power converted to DC 24V by the transformer 600, and an accommodation space 110 When the temperature of the detection sensor 700 that senses the temperature of and the accommodation space 110 sensed by the detection sensor 700 is 7℃ or less, the temperature of the accommodation space 110 is 3℃~5℃ or less. The controller 500 outputs a signal so that power is supplied to the heater 400 so as not to fall off, and when the temperature of the accommodation space 110 is 7°C or higher, the controller 500 outputs a signal to cut off the power supplied to the heater 400 and , Each of the transformers 600 are installed to limit power application according to a signal output by the controller 500.

이로인해 본체(100)의 수용공간(110)의 온도를 감지센서(700)가 감지하여 컨트롤러(500)로 전달하고, 상기 컨트롤러(500)는 감지센서(700)에 의해 감지된 수용공간(110)의 온도가 영상 7℃ 이상인지 7℃ 이하인지를 비교하여, 상기 감지센서(700)에 의해 감지된 수용공간(110)의 온도가 영상 7℃ 이하이면 히터(400)에 전원이 인가되도록 트랜스(600)를 작동시키고, 상기 감지센서(700)에 의해 감지된 수용공간(110)의 온도가 영상 7℃ 이상이면 히터(400)에 공급되는 전원이 차단되도록 트랜스(600)를 작동시키게 된다. Due to this, the detection sensor 700 detects the temperature of the accommodation space 110 of the main body 100 and transmits it to the controller 500, and the controller 500 is the accommodation space 110 sensed by the detection sensor 700. ) By comparing whether the temperature of the image is 7°C or more or 7°C or less, and if the temperature of the receiving space 110 sensed by the detection sensor 700 is 7°C or less, the power is applied to the heater 400. When the temperature of the receiving space 110 sensed by the detection sensor 700 is 7° C. or higher, the transformer 600 is operated so that the power supplied to the heater 400 is cut off.

이때, 상기 트랜스(600)로 부터 인가되는 전원에 의해 히팅이 이루어지는 히터(400)의 열에 의해 겨울철과 같이 주변온도가 급격히 저하되는 경우에도 본체(100)의 수용공간(110) 온도가 영상 3℃~ 5℃ 이하로 떨어지지 않아 보빈(200)에 감긴 상태로 수용공간(110)에 보관되고 있는 소방호스(300)가 내부에 남아있는 소화용수에 의해 동파가 발생하지 않게 된다. At this time, even when the ambient temperature is rapidly decreased, such as in winter, by the heat of the heater 400, which is heated by the power applied from the transformer 600, the temperature of the receiving space 110 of the main body 100 is 3°C. The fire hose 300, which is stored in the receiving space 110 in a state wound around the bobbin 200, does not fall below ~ 5°C, and freezes do not occur due to the fire extinguishing water remaining therein.
