본 발명은 내연기관의 화염분출방지용 트랩장치에 관한 것으로, 보다 상세하게는 과열된 내열기관의 오폭 시, 외부로 방출되는 화염을 순차적으로 다중 흡수하고 감압시킴으로써 화염이 외부로 방출되는 것을 효과적으로 상쇄시킬 수 있는 내연기관의 화염분출방지용 트랩장치에 관한 것이다.The present invention relates to a trap device for preventing flame ejection of an internal combustion engine, and more particularly, in the event of a misfire of an overheated heat engine, it is possible to effectively offset the discharge of the flame to the outside by sequentially absorbing and depressurizing the flame released to the outside. The present invention relates to a trap device for preventing flame ejection of an internal combustion engine.

통상적으로 선박, 자동차 등에서는 연료를 기관 내에서 연소시켜 발생된 고온, 고압의 가스를 직접 일에너지로 전환시키는 내연기관을 사용하게되며, 보편적인 내연기관의 구조는 다수의 실린더장치를 구비하고 있는 엔진부로부터 동력을 발생시켜 이 동력을 기계적 운동에너지로 전환하는 시스템으로 이루어져 있다. In general, an internal combustion engine that directly converts high-temperature, high-pressure gas generated by burning fuel in an engine to work energy is used in ships and automobiles, and a general internal combustion engine structure includes a plurality of cylinder devices. It consists of a system that generates power from the engine unit and converts this power into mechanical kinetic energy.

엔진부에는 전동장치인 크랭크부(crank portion)가 연결되어 있고 크랭크부는 크랭크케이스에 의해 둘러싸여져, 크랭크케이스 내부는 엔진의 고온, 고압가스에 의해 비교적 높은 온도 및 압력을 유지하게 되나, 크랭크케이스 내부의 압력이 규정된 압력(통상적으로 0.03~0.05kg/㎠)이상으로 상승하면, 과도한 압력만큼 내부가스를 외부로 유출시켜 크랭크케이스 내부를 항상 정상압력으로 유지시킬 수 있도록 하고 있다. A crank portion, which is a transmission device, is connected to the engine portion, and the crank portion is surrounded by the crankcase, and the inside of the crankcase maintains a relatively high temperature and pressure by the high temperature and high pressure gas of the engine, but inside the crankcase When the pressure rises above the prescribed pressure (usually 0.03 ~ 0.05kg / ㎠), the internal gas is discharged to the outside by excessive pressure so that the inside of the crankcase can be always maintained at normal pressure.

크랭크케이스 내부에 오폭에 의해 화염이 발생될 경우에는 화염이 외부로 넓게 유출되어 크랭크케이스 주위의 각종 기계장치 뿐만 아니라 인체에 치명적인 피해를 끼치게 되므로, 이를 방지하기 위해 내연기관의 엔진부 주위에는 폭발 시 화염이 외부로 분출되는 것을 차단할 수 있는 화염분출방지용 트랩장치가 설치된다.If a flame is generated by an error in the crankcase, the flame will flow out to the outside, causing not only various mechanisms around the crankcase, but also fatal damage to the human body. The flameout trap device is installed to block the flame outwards.

화염분출방지용 트랩장치는 외부로 유출되는 화염을 다수의 스트랩이 형성하는 판면사이를 통과시키면서 흡수 및 감쇄시키도록 하고 있으나, 종래의 이러한 화염분출방지용 트랩장치는 다수의 스트랩이 단순하게 겹쳐져 있는 구조로 되어있기 때문에 화염의 열기 및 고압을 효과적으로 상쇄시키지 못한다는 문제점이 있었다.The flame spray trap device absorbs and attenuates the flame flowing out through the plate surface formed by the plurality of straps. However, the conventional flame spray trap device has a structure in which a plurality of straps are simply overlapped. Since there is a problem that does not effectively offset the heat and high pressure of the flame.

상술한 바와 같은 문제점을 해결하기 위해 안출된 본 발명은, 내열기관의 오 폭 시 외부로 방출되는 화염을 효과적으로 흡수 및 상쇄시킬 수 있는 내연기관의 화염분출방지용 트랩장치를 제공하는 것을 목적으로 한다.The present invention devised to solve the problems as described above, an object of the present invention is to provide a flameout prevention trap device of an internal combustion engine that can effectively absorb and offset the flame emitted to the outside in the event of an error of the heat-resistant engine.

상술한 바와 같은 목적 달성을 위한 본 발명은, 크랭크케이스의 개구부 외측둘레에 설치되며, 다수의 철선부재가 교차되고 겹쳐진 망구조에 의해 상기 크랭크케이스 외부로 유출되는 화염을 1차적으로 흡수 및 분산시키는 1차화염흡수망부와; 상기 1차화염흡수망부 외측에 확장된 빈 공간부를 제공하여, 상기 1차화염흡수망부를 통과하며 분산 및 약화된 화염의 압력을 감소시키는 감압확산공간부와; 상기 감압확산공간부 외측에 상기 1차화염흡수망부와 같은 망구조로 설치되어, 상기 1차화염흡수망부와 감압확산공간부에서 1차로 흡수되고 감압된 화염을 2차로 흡수 및 분산시키는 2차화염흡수망부와; 판면에 방사형으로 요철이 형성된 다수의 스트랩이 겹쳐진 구조로 상기 2차화염흡수망부 외측에 설치되어, 상기 2차화염흡수망부를 통과한 잔여의 화염을 상기 스트랩의 사이에 형성된 도출공을 통과하면서 3차적으로 흡수시키고 산소결핍에 의한 불연소로 미불꽃 상태로 토출시키는 화염도출덕트부;를 포함하여 구성되는 내연기관의 화염분출방지용 트랩장치를 기술적 요지로 한다.The present invention for achieving the object as described above, is installed on the outer periphery of the opening of the crankcase, the first to absorb and disperse the flame flowing out of the crankcase by a plurality of wire members cross and overlap the network structure A primary flame absorption network; A reduced pressure diffusion space portion configured to provide an empty space portion extended outside the primary flame absorption network portion and to reduce pressure of the dispersed and weakened flame passing through the primary flame absorption network portion; Secondary flame is installed in the same structure as the primary flame absorption network portion outside the reduced pressure diffusion space portion, the primary flame absorption network portion and the secondary flame absorbing and dispersing the decompressed flame secondary in the reduced pressure diffusion space portion Absorption net part; A plurality of straps having radially irregularities formed on the plate surface are installed on the outside of the secondary flame absorption network portion, and the remaining flame passing through the secondary flame absorption network portion passes through the lead hole formed between the straps. Flame extraction duct unit for absorbing and discharged in a non-flame state by non-combustion due to oxygen deficiency;

여기서, 1차화염흡수망부는, 내외측에 접하는 다수의 볼트에 의해 형상유지되고 고정설치됨이 바람직하다.Here, it is preferable that the primary flame absorption net portion is shaped and fixed by a plurality of bolts in contact with the inside and the outside.

따라서, 내열기관의 오폭 시 외부로 방출되는 화염의 열기를 다수의 화염흡수망 및 덕트에 의해 1, 2, 3차로 다중으로 흡수 및 감쇄시키고, 화염흡수망 사이에 공간부를 형성하여 내압을 효과적으로 감쇄시킴으로써 화염이 외부로 방출되는 것을 효과적으로 방지시킬 수 있다는 이점이 있다.Therefore, the heat of flame discharged to the outside in case of misfire of heat-resistant engine is absorbed and attenuated in multiples 1, 2, and 3 by multiple flame-absorbing nets and ducts, and a space is formed between flame-absorbing nets to effectively reduce internal pressure. By doing so, there is an advantage that the flame can be effectively prevented from being released to the outside.

또한, 화염이 다수의 화염흡수망과 감압공간부를 거쳐 고르게 분산 방출되면서 우수한 감압 및 냉각성능을 구현시킬 뿐만 아니라, 화염흡수망과 덕트에 자체에 가해지는 충격을 최소화시켜 수명을 보다 향상시킬 수 있다는 다른 이점이 있다.In addition, the flame is evenly distributed and discharged through a plurality of flame absorption networks and decompression spaces to realize excellent decompression and cooling performance, as well as to minimize the impact on the flame absorption network and the duct itself to improve the lifespan. There is another advantage.
