Description
본 고안은 LP가스 차량용 가스 검출 및 안전장치에 관한 것으로서, 더욱 상세하게는 엔진룸의 가스 충전상태를 확인하고, 가스 충전시 이를 알리는 경고신호를 출력함과 동시에 소화액을 분사하여 안전을 도모할 수 있도록 하는 LP가스 차량용 가스 검출 및 안전장치에 관한 것이다.The present invention relates to a gas detection and safety device for LP gas vehicles, and more specifically, to check the gas filling state of the engine room, and outputs a warning signal informing of this when filling the gas and at the same time spraying the extinguishing fluid can promote safety. It relates to a gas detection and safety device for LP gas vehicle.
종래 LP가스 차량에 적용되고 있는 LP가스 장치를 제2도에 의해서 살펴보면, 자동차의 후바에 설치되어 있는 가스탱크(101)에 충전되어 있는 액체상태의 LP가스는 여과기(102)를 통하여 이물질이 필터링되어 전자밸브(103)에 공급된다. 이때 전자밸브(103)는 운전자가 차량을 운행하기 위해서 점화스위치(105)를 조작함에 따라 배터리(104)에서 출력되는 전원이 인가되어 “오픈”된다. 즉, 차량을 운행하지 않는 경우 가스탱크(101)에 충전되어 있는 LP가스가 엔진룸을 비롯하여 외부로 배출되는 것을 방지하기 위해서 전자밸브(103)를 닫는다.Referring to the LP gas apparatus applied to the conventional LP gas vehicle in Figure 2, the liquid LP gas filled in the gas tank 101 installed in the rear of the vehicle is filtered through the filter 102 foreign matters And the solenoid valve 103 is supplied. At this time, the solenoid valve 103 is “opened” by applying the power output from the battery 104 as the driver operates the ignition switch 105 to drive the vehicle. That is, when the vehicle is not running, the solenoid valve 103 is closed to prevent the LP gas filled in the gas tank 101 from being discharged to the outside, including the engine room.
이어서, 가스탱크(101)에서 배출되는 고압의 가스는 2단의 조정기 즉, 고압 조정기와 저압조정기로 구성되어 있는 조정기(106)에 의해 저압의 가스로 조정되어 혼합기(107)로 공급된다. 이에 따라 엔진(108)의 연소실에 이 가스가 공급되어 연소됨으로써 엔진의 추진력을 얻을 수 있는 것이다.Subsequently, the high pressure gas discharged from the gas tank 101 is adjusted to a low pressure gas by a regulator 106 composed of two stage regulators, that is, a high pressure regulator and a low pressure regulator, and is supplied to the mixer 107. As a result, the gas is supplied to the combustion chamber of the engine 108 and combusted to obtain the driving force of the engine.
그러나 LP가스의 경우 이를 운전자가 육안으로 확인할 수 없어 안전사고의 요인이 된다. 특히, 많은 량의 가스를 저장하기 위해서 가스를 고압의 가스를 충전하게 되고, 또한 엔진룸이 밀폐되어 있는 상태에서 전기적인 스파크나 혹은 기계적인 충돌에 의한 불꽃이 엔진룸에 충전되어 있는 가스를 착화시키면 안전사고가 발생된다.However, LP gas cannot be checked by the driver's eyes, which causes a safety accident. In particular, in order to store a large amount of gas, the gas is filled with a high-pressure gas, and in the state where the engine room is sealed, the sparks from the electric spark or the mechanical collision are ignited in the engine room. Doing so will cause a safety accident.
즉, 밀폐되어 있는 엔진룸에는 점화코일을 비롯하여 많은 전기장치가 구성되어 주행하는 차량의 기계적인 충돌에 의해서 불꽃이 발생되어 안전사고를 유발하는 등의 문제점이 있다.That is, there is a problem that a spark is generated by a mechanical collision of a vehicle in which a large number of electric devices, including an ignition coil, are configured in the engine room, which is closed, causing a safety accident.
또한, 상기한 바와 같은 안전사고를 줄이기 위해서 엔진룸을 수시로 열어 환기시키거나 혹은 별도의 장비를 이용하여 엔진룸의 가스 충전상태를 확인하고 가스 충전시 이 원인을 찾아 제거해야 하는 번거로움이 있다.In addition, in order to reduce safety accidents as described above, the engine room is frequently opened and ventilated, or separate equipment is used to check the gas filling state of the engine room, and when gas is filled, it is troublesome to find and remove the cause.
이에 본 고안은 상기한 바와 같은 종래의 문제점을 없애기 위해서 제안된 것으로 엔진룸의 가스 충전상태를 확인하고, 가스 충전시 이를 알리는 경고신호를 출력하여 가스의 누출상태를 알릴 수 있도록 하는 LP가스 차량용 가스 검출 및 안전 장치를 제공하는데 그 목적이 있다.The present invention has been proposed to eliminate the above-mentioned problems as described above LP gas vehicle gas to check the state of gas filling of the engine room, and output a warning signal to inform this when the gas is filled LP gas vehicle gas Its purpose is to provide a detection and safety device.
본 고안의 또다른 목적은 장시간동안 가스의 충전상태가 지속되면 소화액을 분사하여 불꽃발생에 의한 화재사고를 미연에 방지할 수 있도록 하는 LP가스 차량용 가스 검출 및 안전장치를 제공하는데 그 목적이 있다.Another object of the present invention is to provide a gas detection and safety device for LP gas vehicle that can prevent fire accidents caused by the generation of sparks by spraying the extinguishing liquid when the state of charge of gas continues for a long time.

이하, 본 고안의 일 실시에에 따른 구성을 첨부된 예시도면과 함께 보다 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings illustrating the configuration according to an embodiment of the present invention in more detail as follows.
제1도는 본 고안의 실시예에 따른 구성도이다.1 is a block diagram according to an embodiment of the present invention.
본 고안은 제1도에 도시한 바와 같이 엔진룸(16)의 가스 충전상태를 감지하는 가스감지센서(21)와, 상기 가스감지센서(21)에서 출력되는 검출데이터를 인가받아 가스의 충전상태를 판단하고 충전시 구동신호를 출력하는 엔진 전자제어장치(22)와, 상기 엔진 전자제어장치(22)으 구동신호에 의해 소화액 충전기(24)의 소화액을 분사노즐(26)로 배출하는 밸브(25)로 구성되어 있다.According to the present invention, as shown in FIG. 1, a gas detection sensor 21 for detecting a gas charging state of the engine room 16 and detection data output from the gas detection sensor 21 are applied to a gas charging state. The engine electronic control unit 22 for determining and outputting a driving signal at the time of charging, and the valve for discharging the extinguishing liquid of the extinguishing liquid charger 24 to the injection nozzle 26 by the driving signal of the engine electronic control unit 22 ( 25).
또한, 상기 엔진룸(16)에 가스 충전시 이를 알리는 경고등(23)을 엔진 전자 제어장치(22)에 접속하여 운전자로 하여금 엔진룸(16)의 가스 충전상태를 알 수 있도록 한다.In addition, a warning lamp 23 for notifying the engine room 16 of the gas filling is connected to the engine electronic control unit 22 so that the driver can know the state of gas filling of the engine room 16.
이와 같이 구성된 본 고안의 작용을 설명한다.The operation of the present invention configured as described above will be described.
종래의 LP가스 차량에서와 같이 본 고안에서도 시동을 걸면, 엔진 전자제어장치(22)의 제어로 전자밸브(12)가 “오픈”되면서 가스탱크(11)에 충전되어 있던 가스가 고압조정기(14)와 전압조정기(15)로 이루어진 조정기(13)에 의해서 저압상태의 가스로 변환되어 혼합기(17)에 공급된다.In the present invention, as in the conventional LP gas vehicle, when the engine is started, the solenoid valve 12 is “opened” under the control of the engine electronic controller 22, and the gas charged in the gas tank 11 is filled with the high pressure regulator 14. ) And the voltage regulator 15 converts the gas into a low pressure gas and supplies it to the mixer 17.
그리고, 상기 혼합기(17)를 통해 엔진(18)의 연소실에 공급된 가스가 점화플러그(27)의 착화동작으로 연소되면서 엔진(18)은 추진력을 얻을 수 있다. 즉, 혼합기(17)를 통해 가스가 공급되면, 배터리(20)에 출력되는 전원이 점화코일(19)에 의해 승압되어 점화플러그(27)에 공급되므로 착화동작이 이루어진다.In addition, as the gas supplied to the combustion chamber of the engine 18 through the mixer 17 is burned by the ignition operation of the spark plug 27, the engine 18 may obtain a driving force. That is, when gas is supplied through the mixer 17, the power output to the battery 20 is boosted by the ignition coil 19 and supplied to the ignition plug 27 so that the ignition operation is performed.
또한, 엔진룸(16)에 설치되어 있는 가스감지센서(26)는 엔진룸(16)의 가스충전상태를 감지하고, 가스충전시 이를 알리는 검출데이터를 엔진전자제어장치(22)에 공급한다.In addition, the gas detection sensor 26 installed in the engine room 16 detects the gas charging state of the engine room 16 and supplies the detection electronic data to the engine electronic control device 22 informing the gas charging state.
그리고, 엔진 전자제어장치(22)는 가스감지센서(26)의 검출데이터에 의해 엔진룸(16)의 가스 충전상태를 판정하고, 가스 충전시 경고등(23)을 구동시켜 운전자에게 이를 알린다. 물론 경고등(23)은 운전자가 수시로 확인할 수 있도록 운전석의 계기판에 형성되어 있다.Then, the engine electronic controller 22 determines the gas charging state of the engine room 16 based on the detection data of the gas detection sensor 26, and drives the warning lamp 23 to inform the driver of the gas charging state. Of course, the warning light 23 is formed in the dashboard of the driver's seat so that the driver can check at any time.
이어서 소정시간이 경과하도록 운전자가 이를 제거하지 않을 경우나 혹은 엔진룸(16)에 가스가 충전되어 있는 상태에서 전기장치나 혹은 기계적인 접촉으로 불꽃이 발생되는 경우 밸브(25)를 “오픈”시킨다.The valve 25 is then "opened" if the driver does not remove it for a predetermined time, or if sparks are generated by electrical or mechanical contact with gas filled in the engine compartment 16. .
이에 따라, 소화액 충전기(24)에 충전되어 있던 소화액이 밸브(25)를 거쳐분사노즐(26)에 공급되어 엔진룸(16)에 분사된다.Accordingly, the extinguishing liquid filled in the extinguishing liquid charger 24 is supplied to the injection nozzle 26 via the valve 25 and injected into the engine room 16.
특히, 분사노즐(26) 분사방향을 점화코일(19)과 같이 불꽃이 빈번하게 발생하는 지점으로 조절함으로써, 엔진룸(16)에 충전되어 있는 가스의 폭발로 인한 안전사고를 방지할 수 있다.In particular, by adjusting the injection direction of the injection nozzle 26 to the point where the flame frequently occurs, such as the ignition coil 19, it is possible to prevent a safety accident due to the explosion of the gas charged in the engine room (16).
이상에서와 같이 본 고안은 엔진룸의 가스 충전상태를 검출하고, 가스 충전시 이를 알리는 경고신호를 출력함으로써, 운전자는 엔진룸의 가스 충전상태를 확인할 수 있다. 또한, 장시간이 경과하도록 엔진룸에 충전되어 있는 가스가 제거되지 않거나 혹은 충전된 가스에 불꽃이 점화되어 화재가 발생되면 소화액을 분사함으로써, 화재사고를 미연에 방지할 수 있는 것이다.As described above, the present invention detects the gas filling state of the engine room and outputs a warning signal informing the gas filling state, so that the driver can check the gas filling state of the engine room. In addition, when the gas charged in the engine room is not removed for a long time or a fire is generated by sparking the filled gas, a fire extinguishing liquid is sprayed to prevent a fire accident.
