본 발명은 오일압력을 이용한 잠수함용 디젤기관의 폐기밸브 자동제어구조에 관한 것으로서, 좀더 상세하게는 잠수함의 스노클 항해(Snorkel Operation)중 작동 되는 디젤기관의 시동과 정지과정에서 배기가스를 배출하는 폐기밸브의 개폐를 디젤기관의 오일압력으로서 원격조정으로 자동화하여 승조원의 오작동을 미연에 방지하고, 스노클 심도에서 디젤기관의 시동을 신속하게 수행할 수 있도록 하여 승조원의 편의 및 잠항에 따른 신뢰성을 높일 수 있도록 한 것이다.The present invention relates to an automatic control structure of a waste valve of a diesel engine for submarines using oil pressure, and more particularly, to discharge exhaust gas during start and stop of a diesel engine operated during snorkel operation of a submarine. Automated opening / closing of valves by remote control as oil pressure of diesel engine prevents crew from malfunctioning and speeds up the start of diesel engine at snorkel depth, thus enhancing the convenience and reliability of crew members. It would be.

일반적으로 잠수함의 디젤기관, 폐기밸브, 폐기가스관에 대한 일반사항을 알아보면, 잠수함은 적에게 노출되지 않도록 스노클 심도(Snorkel Depth)에서 디젤기관(Diesel Engine)을 구동하여 축전지(Battery)를 충전한다.In general, when looking at general information about submarine diesel engines, waste valves, and waste gas pipes, submarines charge diesel by driving diesel engines at snorkel depth to prevent exposure to enemies. .

스노클 심도(Snorkel Depth)에서 디젤기관을 구동하려면 연소공기 공급, 배기가스 배출, 연료유 공급 및 저압 냉각해수 공급 등이 필요하고, 주기적으로 윤활유를 교환하여야 한다.Driving a diesel engine at snorkel depth requires the supply of combustion air, exhaust gas, fuel oil and low pressure cooling seawater, and the need for periodic lubricant changes.

또한, 디젤기관 구동을 위한 공기를 흡입하는 스노클 계통(Snorkel System), 공기를 디젤기관에 사용한 후에 생성되는 폐기를 배출하는 폐기 계통(Exhaust Gas System), 디젤기관을 구동하기 위한 연료유 계통(Fuel Oil System), 윤활유 계통(Lubricating Oil System) 및 스노클 심도에서 디젤기관의 냉각수를 공급하는 저압 냉각해수 계통(Cooling Seawater System LP) 등의 디젤기관 관련계통이 필요하다.In addition, a snorkel system (Snorkel System) that sucks air for driving a diesel engine, an Exhaust Gas System for discharging waste generated after using air in a diesel engine, and a fuel oil system for driving a diesel engine (Fuel) Diesel engine related systems such as Oil System, Lubricating Oil System, and Cooling Seawater System LP, which supplies diesel engine coolant at snorkel depth, are needed.

디젤기관의 시동절차에 맞추어 디젤기관 관련계통이 작동되도록 자동화되어 있으나, 폐기계통만은 폐기압력이 형성되지않은 상태에서 폐기밸브를 개방할 경우 외부 해수가 침수할 위험성이 높고, 배기가스가 압축성 유체(Compressible Fluid)로 배기가스의 압력이 가변적이므로 이를 이용하여 자동화하지 못하고 반자동 상태 로 조정하는 경우가 대부분이다.Although the system related to the diesel engine is automated to operate according to the starting procedure of the diesel engine, only the waste system has a high risk of flooding external seawater when the waste valve is opened without the waste pressure being formed, and the exhaust gas is a compressive fluid. As the pressure of exhaust gas is variable with Compressible Fluid, it is not possible to automate using this and it is mostly adjusted to semi-automatic state.

잠수함 배기계통은 스노클 항해 동안 디젤기관 구동에 의하여 발생하는 배기가스(Exhaust Gas)를 함 외로 배출한다. 스노클 항해 동안 외부의 해수압력을 극복하고 디젤엔진의 배기가스를 함 외로 배출할 수 있고 또한 배출되는 배기가스로 인하여 적에게 탐지되지 않도록 설계되어야 한다.The submarine exhaust system discharges exhaust gas generated by driving a diesel engine during snorkel navigation to the outside of the ship. It should be designed to overcome external sea pressure during snorkeling and to exhaust the exhaust of diesel engine to the outside and not be detected by the enemy due to the exhaust.

디젤엔진 시동특성은 디젤엔진 시동동안 함외 배기라인의 해수를 배기가스 에너지를 사용하여 스노클 배기구로 방출하는 특성을 의미하며 배기계통 설계에서 가장 중요하다.Diesel engine start-up characteristics mean the discharge of seawater from an off-line exhaust line to the snorkel exhaust port using exhaust gas energy during diesel engine start-up and is the most important in the exhaust system design.

폐기관(Exhaust Gas Pipe)은 디젤기관의 배압(Back-Pressure) 성능, 배기관의 냉각 온도(Cooling Temperature), 배기관의 압력 손실(Pressure Loss), 해수 배압 (Back-Pressure) 등을 고려하여 관경을 결정한다.Exhaust gas pipe is designed to consider the back pressure of diesel engine, cooling temperature of exhaust pipe, pressure loss of exhaust pipe, and back-pressure of seawater. Decide

스노클 항해 시에는 사령탑(Bridge Fin) 상부까지 연장된 폐기관으로 배출하고, 수상 항해에서는 케이싱(Casing) 측면으로 배출한다.When snorkeling, it is discharged into a waste pipe extending to the upper part of the bridge fin, and in water navigation, it is discharged to the casing side.

참고로, 잠수함에서 작동기기의 에너지원은 전기(Electric Power), 유압(Hydraulic Pressure), 공압(Pneumatic Pressure) 등이 있다.For reference, the energy source of the operating device in the submarine is Electric (Power), Hydraulic (Hydraulic Pressure), Pneumatic (Pneumatic Pressure).

종래의 잠수함에 탑재하는 디젤기관은 스노클 심도(Snorkel Depth)에서 시동 및 정지할 수 있도록 배압에 견디도록 설계되고, 시동과 정지 과정에서 해수가 침수되지 않도록 배기가스(Exhaust Gas) 압력을 감시하여 반자동으로 폐기밸브를 개폐한다. Diesel engines mounted in conventional submarines are designed to withstand back pressure to start and stop at snorkel depth and are semi-automatic by monitoring exhaust gas pressure to prevent seawater from submerging during start and stop. Open and close the waste valve.

수동으로 작동력인 유압이나 공압을 공급하고, 비상시에는 인력을 이용한다.Supply hydraulic or pneumatic pressure manually and use manpower in an emergency.

시동 때는 디젤기관에서 배출되는 배기가스를 디젤기관과 폐기밸브 사이의 폐기가스관(Exhaust Gas Pipe)에 집적하고, 압력계를 설치하여 압력상승을 감시한다.At start-up, the exhaust gas from the diesel engine is accumulated in the exhaust gas pipe between the diesel engine and the waste valve, and a pressure gauge is installed to monitor the pressure rise.

디젤기관은 일정 수준의 배압을 견딜 수 있도록 설계된 것으로, 배기가스를 일시적으로 몇 초(sec)동안 저장할 수 있는 공간이 유지되도록 폐기가스관을 구성하고 있다.The diesel engine is designed to withstand a certain level of back pressure, and constitutes a waste gas pipe to maintain a space for temporarily storing the exhaust gas for a few seconds.

폐기밸브 후단의 폐기가스관에 차있는 해수를 밀고 나갈 수 있는 설계압력에 도달할 때까지 승조원이 압력을 일일이 체크하여 감시하고, 압력이 도달하는 위치에 오면 승조원이 폐기밸브를 직접 개방시켜 준다.The crew checks and monitors the pressure until it reaches a design pressure that can push out the seawater filled in the waste gas pipe at the end of the waste valve, and the crew opens the waste valve directly when the pressure reaches the position.

승조원이 폐기밸브의 개폐를 원격 조종하면, 계통설계에 따라 유압계통이나 공압계통에서 공급되는 압력에 의해 폐기밸브가 개폐되는데, 스노클 항해에 있어, 디젤기관의 시동 과정은 항상 승조원의 주의가 요망되기 때문에 확실한 압력체크가 이루진 후에만 반자동(Semi-Automation) 단계에서 폐기밸브의 개방으로 배기가스를 배출할 수 있도록 되어 있었다.When the crew remotely controls the opening and closing of the waste valve, the waste valve is opened and closed by the pressure supplied from the hydraulic system or the pneumatic system according to the system design.In snorkel navigation, the starting process of the diesel engine always requires the attention of the crew. Therefore, the exhaust gas was discharged by opening the waste valve in the semi-automation stage only after a certain pressure check was made.

결국, 폐기밸브의 개폐시점을 승조원이 결정하므로 오작동 가능성이 있기 때문에 해수가 침수할 위험성을 배제할 수 없는 문제점이 있었다.As a result, since the crew determines the opening and closing time of the waste valve, there is a problem that can not rule out the risk of seawater flooding because there is a possibility of malfunction.

본 발명은 상기와 같이 점을 위하여 발명된 것으로, 잠수함의 압력선체내에 설치되어 잠항의 추진기능을 하는 디젤기관에 있어 디젤기관의 시동과 정지과정에서 배기가스를 배출하는 폐기밸브의 개폐를 디젤기관의 오일압력으로서 원격조정으 로 자동화하여 승조원의 오작동을 미연에 방지하고, 스노클 심도에서 디젤기관의 시동을 신속하게 수행할 수 있도록 하여 승조원의 편의 및 잠항에 따른 신뢰성을 높일 수 있도록 하는데 그 목적이 있다.The present invention has been invented for the above-described point, the diesel engine is installed in the pressure hull of the submarine in the diesel engine functioning the submarine propulsion function to open and close the waste valve to discharge the exhaust gas during the start and stop of the diesel engine The oil pressure of the crew can be automated by remote control to prevent malfunction of the crew in advance and to start the diesel engine quickly at the snorkel depth so that the crew can increase the convenience and reliability of the submerged ship. have.

A three-way control valve 7 remotely controlled by the generated oil pressure is provided, and a three-way control valve 7 is connected from the external waste valve 2 'side to supply oil from the oil pipe 6. A remote control valve 8 for controlling the opening and closing of hydraulic oil or pneumatic pressure is provided to control the internal and external waste valves 2 and 2 '.

또한 본 발명은 원격조정밸브(8)가 디젤기관(3)에 엔진오일을 항상 공급할 수 있도록 공급회로가 기본적으로 구성되고, 디젤기관의 시동과 정지 과정에서만 일시적으로 원격조정밸브(8)를 전환하여 엔진오일 압력을 조종압력으로 이용할 수도 있다.In the present invention, the supply circuit is basically configured so that the remote control valve 8 can always supply engine oil to the diesel engine 3, and temporarily switches the remote control valve 8 only during the start and stop of the diesel engine. The engine oil pressure can be used as the control pressure.

상기와 같은 구조에 있어, 상기 3방향 조절밸브(7)는 디젤기관(3)의 오일(Lubricating Oil) 압력을 분지하여 제어 압력으로 공급할 수 있도록 한 것으로, 원격조종이 가능하게 된다.In the structure as described above, the three-way control valve (7) to branch the oil (Lubricating Oil) pressure of the diesel engine (3) to be supplied as a control pressure, it is possible to remote control.

상기 디젤기관의 시동과 정지를 감시하고 이에 맞추어 3방향 조절밸브(7)를 전환할 수 있도록 하는 제어방식으로서, 디젤기관(3)의 시동과 정지 때에 형성되는 오일 압력에 따라 폐기밸브(2)(2')가 개폐될 수 있도록 폐기밸브를 개폐하는 원격조종밸브(8)에 제어용 배관을 연결하고, 운용자의 판단자료로 활용할 수 있도록 조 종반(Control Panel)에 전시한다. As a control method for monitoring the start and stop of the diesel engine and switching the three-way control valve 7 accordingly, the waste valve 2 according to the oil pressure formed at the start and stop of the diesel engine 3. The control pipe is connected to the remote control valve 8 that opens and closes the waste valve so that the 2 'can be opened and closed, and is displayed on the control panel so that it can be used as the operator's judgment data.

상기 디젤기관(3)은 디젤기관의 시동과 정지 과정에서 내,외부측 폐기밸브(2)(2')의 개폐를 자동화할 수 있도록 디젤기관(3)의 오일을 일시적으로 폐기밸브의 작동 압력으로 공급할 수 있으며, 상기 내,외부측 폐기밸브(2)(2')를 개폐하기 위한 작동력은 압력송신기(5)에서 감지되는 압력정도로서 종래와 같이 유압이나 공압을 이용할 수 있으며, 비상시에는 인력을 이용하지만, 유압이나 공압의 공급을 원격 조종하도록 한다.The diesel engine 3 temporarily operates the oil pressure of the waste valve to temporarily discharge oil from the diesel engine 3 so as to automate the opening and closing of the inner and outer waste valves 2 and 2 'during the start and stop of the diesel engine.
