It is provided through (9), and provided with a cylinder oil collecting device (3), one end of the cylinder oil collecting ball (9), one end is removed and mounted, and on the lower side of the cylinder oil collecting device (3) The cylinder oil discharge pipe 10 is provided, and the valve 6 is inserted into the cylinder oil collecting device 3 so as to be positioned above the cylinder oil discharge pipe 10, and the valve oil discharge pipe 10 is located at the front of the valve 6.

상기와 같은 구성을 참조하여 본 발명의 작용을 설명하면 다음과 같다.Referring to the configuration as described above the operation of the present invention.

실린더유 채취 장치(3)를 실린더 벽(11)의 일측 상부에 부착하고, 실린더(1) 내부의 압력과 장력 조정 장치(4)를 이용하여 별도의 외부 동력 없이 실린더유를 채취할 수 있도록 한다.Attach the cylinder oil collecting device 3 to the upper side of the cylinder wall 11, and use the pressure and tension adjusting device 4 inside the cylinder 1 to collect the cylinder oil without any external power. .

실린더(1) 벽에 부착된 실린더유 채취 장치(3) 의 수동밸브(7)를 연 후 장력 조정 장치(4)를 조정하여 실린더(1) 내부 압력이 최대가 될 때 밸브(6)가 열리면서 실린더 벽(11)에 도포된 실린더유가 실린더(1) 내부 압력에 의해서 유입될 수 있도록 한다.Open the manual valve (7) of the cylinder oil collecting device (3) attached to the wall of the cylinder (1), and then adjust the tension adjusting device (4) to open the valve (6) when the pressure inside the cylinder (1) reaches maximum. The cylinder oil applied to the cylinder wall 11 can be introduced by the pressure inside the cylinder 1.

즉, 장력 조정 장치(4)를 조정하여 상기 장력 조정 스프링(5)의 압력을 조정하면 상기 실린더(1) 내부의 압력이 최대가 되면 상기 밸브(6)가 열리고 상기 실린더(1) 내부의 압력이 내려가면 상기 장력 조정 장치(4)에 의해 조정된 상기 장력 조정 스프링(5)의 압력에 의해 상기 밸브(6)가 닫히게 된다. 상기와 같이 실린더(1) 내부의 압력차에 의하여 상기 밸브(6)가 열리고 닫힘으로써 상기 장력 조정 장치(4)를 조정하여 상기 장력 조정 스프링(5)의 압력을 조정함으로써 1회에 채취할 수 있는 시료의 양을 조절할 수 있다.That is, when the tension adjusting device 4 is adjusted to adjust the pressure of the tension adjusting spring 5, when the pressure inside the cylinder 1 becomes the maximum, the valve 6 opens and the pressure inside the cylinder 1 is increased. When the pressure is lowered, the valve 6 is closed by the pressure of the tension adjusting spring 5 adjusted by the tension adjusting device 4. As described above, the valve 6 is opened and closed due to the pressure difference inside the cylinder 1, so that the tension adjusting device 4 is adjusted to adjust the pressure of the tension adjusting spring 5 to be collected at a time. The amount of sample present can be controlled.

상기와 같이 밸브(6)가 열려 있는 시간동안 채취된 실린더유는 상기 실린더유 배출관(10)을 통해 배출되면서 별도의 시료 채취 용기에 채취된다.As described above, the cylinder oil collected during the time that the valve 6 is opened is discharged through the cylinder oil discharge pipe 10 and collected in a separate sampling container.

일시적인 시료 채취의 필요성이 없을 경우에는 실린더유 채취 장치(3)에 부착된 장력 조정 장치(4)를 조정하여 상기 장력 조정 스프링(5)의 압력을 높임으로써 상기 밸브(6)가 열리지 않도록 할 수 있으며, 또한 안전을 위해서 상기 수동 밸브(7)를 상기 실린더유 채취 장치(3)의 일측에 설치하여 확실한 잠금과 함께 실린더유 채취 장치(3)의 장력 조정 스프링(5)을 보호할 수 있도록 한다.If there is no need for temporary sampling, the valve 6 may not be opened by adjusting the tension adjusting device 4 attached to the cylinder oil collecting device 3 to increase the pressure of the tension adjusting spring 5. Also, for safety, the manual valve 7 is installed at one side of the cylinder oil collecting device 3 so as to protect the tension adjusting spring 5 of the cylinder oil collecting device 3 with a secure locking. .

또한 실린더유 채취 장치(3)가 장기적으로 불필요할 경우에는 실린더유 채취 장치(3)를 탈착한 후 실린더(1) 내부의 폭발 가스 누출을 방지하기 위해 별도로 고안한 일측면 중앙부에 마개 돌기(81)가 돌출 형성된 기밀 유지용 마개(8)를 상기 실린더유 채취 공(9)에 삽입 장착하여 연소 잔류물 등으로 인한 실린더유 채취 공(9)의 막힘을 방지 할 수 있도록 한다.In addition, when the cylinder oil collecting device 3 is unnecessary for a long term, the plug oil protrusion 81 is detached from the cylinder oil collecting device 3 and then attached to the central portion of one side of the cylinder 1 to prevent the leakage of the explosive gas inside the cylinder 1. The airtight stopper 8 is formed to be inserted into the cylinder oil collecting hole 9 so as to prevent clogging of the cylinder oil collecting ball 9 due to combustion residues.

본 발명은 상술한 특정의 바람직한 실시예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 고안이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형실시가 가능한 것은 물론이고, 그와 같은 변경은 청구범위 기재의 범위 내에 있게 된다.The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by those skilled in the art without departing from the gist of the present invention as claimed in the claims. Of course, such changes will fall within the scope of the claims.

본 발명은 저속 2행정 크로스헤드 기관의 실린더유를 용이하게 채취 할 수 있도록 함으로써 엔진의 윤활 상태와 적당한 실린더유 공급 상태를 수시로 확인할 수 있도록 하여 엔진의 운전 상태 및 엔진에 사용되는 연료 상태에 따라서 수시도 실린더유의 공급량을 가감할 수 있어 실린더유를 절감할 수 있으며, 채취된 실린더유의 분석을 통하여 엔진 상태 진단을 용이하게 할 수 있음은 물론 저속 2행정 크로스헤드 기관의 운전비 절감과 엔진 수명이 연장에 도움을 주며, 더불어 과도한실린더 오일 공급으로 인한 대기오염 예방을 할 수 있도록 하여 매우 유용한 발명인 것이다.The present invention allows the cylinder oil of the low-speed two-stroke crosshead engine to be easily collected so that the lubrication state of the engine and the appropriate cylinder oil supply state can be checked at any time, depending on the operating state of the engine and the fuel state used in the engine. In addition, the amount of cylinder oil supplied can be reduced or reduced, which can reduce the amount of cylinder oil. The analysis of the collected cylinder oil facilitates the diagnosis of the engine condition, as well as reducing the operating cost and extending the engine life of the low-speed two-stroke crosshead engine. It is a very useful invention that helps to prevent air pollution due to excessive cylinder oil supply.
