Description

전력공급장치가 장착된 ＣＮＧ 튜브 트레일러{CNG Tube Trailer with battery}CNC Tube Trailer with Power Supply {CNG Tube Trailer with battery}

본 발명은 다수개의 CNG 튜브가 내부에 설치되어 있는 스키드케이스의 내부 일측에 냉방장치 및 전력공급장치를 설치하여 스키드케이스의 내부 공기를 항상 일정하게 저온으로 유지시킴으로써, CNG 가스의 충전효율을 높여 안전하게 충전, 운송 또는 사용할 수 있도록 한 CNG 튜브 트레일러에 관한 것이다.The present invention installs a cooling device and a power supply device on one side of the skid case in which a plurality of CNG tubes are installed therein, thereby keeping the air inside the skid case at a constant low temperature at all times, thereby increasing the charging efficiency of the CNG gas safely. A CNG tube trailer that can be filled, transported, or used.

일반적으로 CNG 튜브 트레일러는 천연가스 차량 보급율 저조의 요인이라고 할 수 있는 CNG 충전소가 부족한 문제점과 CNG 충전소의 건설에 많은 시간과 비용이 소요되는 문제점과 주거지에 고압가스의 배관라인이 구축되어야 하는 위험성으로 인한 민원제기 등의 문제점을 해소하기 위하여 개발된 특수차량으로서, CNG 가스를 저장할 수 있는 튜브를 스키드케이스 내부에 고정시킨 후 전면에는 안전변을 부착하고 후면에는 CNG 충전을 위한 메니폴드를 조립한 스키드케이스를 샤시(바퀴달린부분)위에 장착시켜 트랙터를 이용해 CNG 가스를 저장, 이동 및 충전이 가능토록 한 것이다. In general, CNG tube trailers have a shortage of CNG filling stations, which can be attributed to the low penetration rate of natural gas vehicles, problems that require a lot of time and cost to build CNG filling stations, and the danger that high-pressure gas pipelines must be built in residential areas. As a special vehicle developed to solve the problems caused by complaints, etc., a tube for storing CNG gas is fixed inside the skid case, and a safety valve is attached to the front and a manifold for assembling the manifold for CNG filling. It was mounted on the chassis, allowing tractors to store, transport and charge CNG gas.

도 1 및 도 2는 종래 CNG 튜브 트레일러를 설명하기 위한 도이다.1 and 2 are views for explaining a conventional CNG tube trailer.

도 1 및 도 2에 도시된 바와 같이 종래 CNG 튜브 트레일러는 크게 운전석을 포함하는 차량 부분인 트랙터(1);와 트랙터(1)의 후방측에 연결 설치되어 화물의 운반에 주로 사용되는 바퀴 달린 샤시(11); 샤시(11)상에 설치된 스키드케이스(12); 스키드케이스(12) 내부에 설치되며 그 내용적이 1000L(리터) 이상이 되는 대용량의 실린더 용기로서 CNG 가스가 충전되는 다수개의 CNG 튜브(13); 다수개의 CNG 튜브(13)를 연결시키며 CNG 튜브(13) 내로 CNG를 충전시키거나 CNG 튜브(13) 내에 충전된 CNG를 방출시키는데 필요한 메니폴더(16); 및 스키드케이스(12) 일측에 설치되며 스키드케이스(12) 내부 온도를 일정한 저온으로 유지시키기 위한 냉방장치(14)로 이루어진다.As shown in FIGS. 1 and 2, the conventional CNG tube trailer is largely equipped with a tractor 1, which is a vehicle part including a driver's seat; and a wheeled chassis mainly used for transporting cargo by being connected to the rear side of the tractor 1; (11); A skid case 12 installed on the chassis 11; A plurality of CNG tubes 13 installed in the skid case 12 and filled with CNG gas as a large-capacity cylinder container whose contents are 1000 L (liter) or more; A manifold 16 which connects the plurality of CNG tubes 13 and is required to fill the CNG into the CNG tube 13 or to discharge the CNG filled in the CNG tube 13; And installed on one side of the skid case 12 and consists of a cooling device 14 for maintaining the temperature inside the skid case 12 at a constant low temperature.

따라서, 종래 CNG 튜브 트레일러(10)는 스키드케이스(12) 내부 상단에 일반 냉장탑차에 이용되는 에어컨형 냉방장치(14)가 장착되는바, 스키드케이스(12)의 내부 공기를 저온으로 유지시켜 CNG 튜브(13)의 충전 효율을 240% 이상 높일 수 있게 된다.Therefore, the conventional CNG tube trailer 10 is equipped with an air conditioner-type air conditioner 14 used for a general refrigeration truck at the upper end of the skid case 12, the CNG by keeping the internal air of the skid case 12 at a low temperature The filling efficiency of the tube 13 can be increased by 240% or more.

한편, 종래 CNG 튜브 트레일러(10)는 트랙터(1)와 샤시(11)가 분리되는 형태로 운영되는바, 도 2와 같이 특정 장소 즉, 충전이 필요한 곳에 스키드케이스(12)가 결합된 샤시(11)를 트랙터(1)로 이동시킨 후 샤시(11)부분은 CNG 충전에 이용되고 트랙터(1)부분은 샤시(11)로부터 분리되어 다른 샤시를 이동시키는데 이용된다.On the other hand, the conventional CNG tube trailer 10 is operated in a manner that the tractor 1 and the chassis 11 are separated, as shown in Figure 2, the chassis where the skid case 12 is coupled to a specific place, that is, charging is required ( After moving 11) to the tractor 1, the chassis 11 portion is used for CNG filling and the tractor 1 portion is separated from the chassis 11 and used to move another chassis.

따라서 종래 CNG 튜브 트레일러(10)에 따르면 일반적으로 샤시(11)를 이동시킬 때에만 트랙터(1)가 연결되므로 냉방장치(14) 또한 트랙터(1)에 의해 이동될 때에만 트랙터(1)로부터 전력을 공급받게 되는데, 일반적으로 CNG 가스는 주위 온도가 높아지게 되면 부피가 팽창하게 되는 통상의 가스가 갖는 특성을 가지고 있는바, 만약 도 2와 같이 샤시(11)와 트랙터(1)가 분리되어 냉방장치(14)가 가동되지 않는 상황에서 장시간 방치되게 되면 스키드케이스(12)의 내부온도가 상승하게 되며, 이에따라 CNG 튜브(13) 내부에 충전되어 있는 CNG 가스가 팽창하게 되어 CNG 튜브(13) 내부에 과도한 압력이 발생되어 급격한 가스의 누출 또는 CNG 튜브(13)가 폭발까지 이르게 하는 중대한 사고로 이어질 수 있는 심각한 문제점이 야기될 수 있으며, 특히 외부의 온도가 급격히 상승되는 한여름의 직사광선과 같은 환경에 노출되는 경우 그 위험성은 더욱 높아질 수 있다.Therefore, according to the conventional CNG tube trailer 10, the tractor 1 is generally connected only when the chassis 11 is moved, so that the air conditioner 14 also receives electric power from the tractor 1 only when it is moved by the tractor 1. In general, the CNG gas has a characteristic of a conventional gas that expands in volume when the ambient temperature is increased. If the chassis 11 and the tractor 1 are separated as shown in FIG. If left unattended for a long time in the situation (14) does not operate, the internal temperature of the skid case 12 is increased, accordingly, the CNG gas charged in the CNG tube 13 is expanded to the inside of the CNG tube 13 Excessive pressure can cause serious problems that can lead to a sudden leak of gas or a serious accident leading to the explosion of the CNG tube (13). The risk may be higher if exposed to an environment such as summer direct sunlight.
