Description
본 발명은 비상구 자동 개폐 장치에 관한 것으로, 보다 상세하게는 건물내에서 화재가 발생시 재연 설비나 주경종의 신호를 받아 순간 전원을 작동하여 건물내의 비상구의 출입문을 자동으로 개폐할 수 있는 비상구 자동 개폐 장치에 관한 것이다.The present invention relates to an emergency exit automatic opening and closing device, more specifically, an emergency exit automatic opening and closing that can automatically open and close the door of the emergency exit in the building by operating the instantaneous power in response to the signal of replay equipment or chief alarm when a fire occurs in the building. Relates to a device.
화재가 발생하면 사람들은 당황하고 공포감에 휩싸이게 되며, 때로는 흥분하여 평상시보다 판단력이 떨어져 우왕자왕하다 연기에 질식되거나 높은 데서 뛰어내려 귀중한 인명 피해를 보게된다. 따라서, 화재 발생시에는 화재 경보기의 뚜껑을깨고, 빨간색 단추를 눌려 화재가 발생했음을 알리고 119로 신고를 한다. 또한, 초기에 소화하기 위하여 분전반이나 차단기 등 전기 스위치를 끄고 석유 난로나 가스 화재에 대비한다.When a fire breaks out, people are embarrassed and frightened. Sometimes they are excited and are less judged than usual, suffocating in smoke or jumping from a high place, causing valuable life loss. Therefore, in the event of a fire break the lid of the fire alarm, press the red button to inform that the fire has occurred and report to 119. In addition, in order to extinguish initially, switch off electrical switches such as distribution boards and breakers, and prepare for an oil stove or a gas fire.
한편, 대형 건물에서 화재가 발생하면 물질이 연소할 때 연기 속에 독성이 강한 가스 등이 많이 포함되어 있으므로, 연기는 짧은 시간에 건물의 수직부분으로 올라간다. 이와 같은 건물의 화재 발생에 대비하여 비상구를 설치하는데, 이 비상구에 설치한 출입문은 화재 발생에 대비하여 개방이 되어 있어야 하나 건물에 들어 있는 사무실의 보안 및 도난 등의 이유로 잠겨 있는 경우가 많다.On the other hand, when a fire occurs in a large building, since the smoke contains a lot of toxic gases in the smoke, the smoke rises to the vertical part of the building in a short time. The emergency exit is installed in the event of a fire in such a building. The doors installed in the emergency exit should be opened in preparation for the fire, but are often locked due to the security and theft of the office in the building.
그런데, 이와 같은 일반적인 비상구의 출입문은 다음과 같은 문제점이 발생한다.However, such a general emergency exit door occurs the following problems.
건물내에서의 화재 발생시 비상구의 출입문은 수동 조작에 의해 개방되어야 하나 건물내의 화재 발생의 특성상 신속한 대응이 어려우며, 자동 조작이 가능한 비상구의 출입문도 화재 발생 초기에 화재 확산을 막기 위하여 전원 스위치를 내리므로 비상구의 출입문을 개폐할 수 없게 된다.In case of fire in the building, the door of emergency exit should be opened by manual operation, but it is difficult to respond quickly due to the nature of fire in the building, and the door of emergency exit which can be operated automatically turns off the power to prevent the spread of fire at the beginning of fire. You will not be able to open or close the exit door.
따라서, 본 발명은 이와 같은 문제점을 해결하기 위한 것으로서, 본 발명은 건물내에서의 화재 발생시에 비상구의 출입문을 순간 전원에 의해 자동으로 개폐할 수 있도록 하는 비상구 자동 개폐 장치를 제공하는데 그 목적이 있다.Accordingly, the present invention is to solve such a problem, the present invention is to provide an emergency exit automatic opening and closing device that can automatically open and close the door of the emergency exit by the instantaneous power in the event of a fire in the building. .
도 1은 본 발명에 따른 비상구 자동 개폐 장치의 일실시예.1 is an embodiment of the emergency exit automatic opening and closing device according to the present invention.

이하, 본 발명의 바람직한 실시예에 대하여 첨부 도면을 참조하여 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명에 따른 비상구 자동 개폐 장치의 일실시예이다.Figure 1 is an embodiment of the emergency exit automatic opening and closing device according to the present invention.
도 1에 있어서, 본 발명은 화재 발생시에 작동하는 재연설비 또는 경종으로부터 소정 전압의 순간 전원이 인가되면 소정 시간 후에 오프되는 타이머(T)(10)와, 순간 전원이 인가되면 소정 시간 후에 오프되어 타이머(10)의 오동작에 대비하는 제1전자개폐기(MC)(20)와, 및 타이머(10)와 제1전자개폐기(MC)(20)가 오프됨에따라 순간 전원을 전기개폐기(60)에 인가시키는 제2전자개폐기(30)를 포함하여 구성한다.1, the present invention is a timer (T) (10) which is turned off after a predetermined time when the instantaneous power of a predetermined voltage is applied from a regeneration facility or a bell operating in the event of a fire, and turned off after a predetermined time when the momentary power is applied The first electronic switch (MC) 20 to prepare for malfunction of the timer 10, and as the timer 10 and the first electronic switch (MC) 20 is turned off, the instantaneous power supply to the electric switch 60 It comprises a second electronic switch 30 to be applied.
상세하게 설명하면, 타이머(10)는 고층 건물내에서의 화재 발생시에 작동하는 재연설비로부터 노드(a, b)로 인가되는 220V의 교류전원을 입력받아 소정시간(수초) 후에 오프(OFF)된다. 타이머(10)가 오프되면 제2전자개폐기(20)가 온(ON)이 되어 비상구의 출입문에 연결된 전기개폐기(60)가 순간 전원에 의하여 작동하여 비상구의 출입문이 개방된다. 이때, 타이머(10)만으로 전기개폐기(60)의 작동이 가능하나 타이머(10)내의 접점이 약해 오동작이 우려되므로 제1전자개폐기(20)를 사용한다.In detail, the timer 10 is turned off after a predetermined time (several seconds) by receiving a 220V AC power supplied to the nodes a and b from a regeneration facility operating in a fire in a high-rise building. . When the timer 10 is off, the second electronic switch 20 is turned on, and the electric switch 60 connected to the door of the emergency exit is operated by the instantaneous power supply so that the door of the emergency exit is opened. At this time, the operation of the electric switch 60 is possible only by the timer 10, but the contact point in the timer 10 is weak, so that the malfunction is concerned, the first electronic switch 20 is used.
제1전자개폐기(20)는 타이머(10)에 연동하여 재연설비로부터 노드(a, b)로 인가되는 220V의 교류전원을 접점스위치(50)를 통해 입력받아 약2초동안 작동되며, 약2초간의 작동 후에 오프되어 제2전자개폐기(30)를 온시킨다. 제2전자개폐기(30)가 온되면 전기개폐기(60)는 작동하여 비상구의 출입문을 개방한다.The first electronic switch 20 is operated for about 2 seconds by receiving 220 V of AC power applied to the nodes (a, b) from the regeneration facility through the contact switch 50 in conjunction with the timer 10. It turns off after a second operation to turn on the second electronic switch 30. When the second electronic switch 30 is turned on, the electric switch 60 operates to open the door of the emergency exit.
한편, 저층 건물내에서의 화재 발생시에 작동하는 경종으로부터 노드(a, b)로 인가되는 24V의 직류전원을 입력받은 타이머(10)는 릴레이(40)의 접점을 이용하여 전기개폐기(60)를 작동시킨다. 이때에도, 타이머(10)내의 접점이 약해 오동작이 우려되므로 제1전자개폐기(20)를 사용하는데, 제1전자개폐기(20)는 타이머(10)에 연동하여 경종으로부터 노드(a, b)로 인가되는 24V의 직류전원을 접점스위치(50)를 통해 입력받아 약2초동안 작동되며, 약2초간의 작동 후에 오프되어 제2전자개폐기(30)를 온시킨다. 제2전자개폐기(30)가 온되면 전기개폐기(60)는 작동하여 비상구의 출입문을 개방한다.On the other hand, the timer 10 that receives the 24V DC power applied to the nodes (a, b) from the bell operating in the event of a fire in a low-rise building uses the contacts of the relay 40 to operate the electrical switch 60. It works. In this case, since the contact point in the timer 10 is weak and there is a fear of malfunction, the first electronic switch 20 is used. The first electronic switch 20 is connected to the timer 10 from the alarm bell to the nodes a and b. The DC power of 24V is input through the contact switch 50 and operated for about 2 seconds, and is turned off after about 2 seconds to turn on the second electronic switch 30. When the second electronic switch 30 is turned on, the electric switch 60 operates to open the door of the emergency exit.
접점스위치(50)는 재연설비 또는 경종으로부터 인가되는 220V 교류 전압 또는 24V 직류 전압을 전기개폐기(60)로 인가시키켜 구동시킨다.The contact switch 50 is driven by applying the 220V AC voltage or 24V DC voltage applied from the regeneration facility or the bellows to the electric switch 60.
이와 같이, 본 발명의 상세한 설명에서는 구체적인 실시예에 관해 설명하였으나, 본 발명의 범주에서 벗어나지 않는 한도 내에서 여러가지 변형이 가능함은 물론이다. 그러므로, 본 발명의 범위는 설명된 실시예에 국한되어 정해져서는 안되며 후술하는 특허청구범위 뿐만 아니라 이 특허청구범위와 균등한 것들에 의해 정해져야 한다.As described above, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined by the claims below and equivalents thereof.
결국, 본 발명에 의한 비상구 자동 개폐 장치에 따르면 다음과 같은 이점이 발생한다.As a result, according to the emergency exit automatic switching device according to the present invention the following advantages occur.
즉, 화재 발생시 건물의 전원 스위치가 작동을 멈춤에도 불구하고 비상구의 출입문에 설치된 전기개폐기에 순간 전원을 입력하여 작동시킴으로써 출입문을 개방하여 신속하게 대피할 수 있다.In other words, even if the power switch of the building stops operation in the event of a fire, by opening the door by instantaneous power input to the electrical switch installed in the door of the emergency exit can be evacuated quickly.
