본 발명은 윤활유 높이 경고장치에 관한 것으로, 보다 상세하게는 윤활유탱크에 설치되어 윤활유 높이에 따라 작동되는 플로트 바에 의하여 윤활유의 높고, 낮음을 파악하여 특정신호를 외부에 송출 하며, 별도의 방유장치 없이도 사용이 가능하도록 하여 장치를 간소화 한 중속 추진용 엔진의 윤활유 탱크에 사용되는 윤활유 높이 경고 장치에 관한 것이다.The present invention relates to a lubricating oil level warning device, and more particularly, it detects the high and low lubricating oil by a float bar installed in the lubricating oil tank and operates according to the lubricating oil level, and transmits a specific signal to the outside. The present invention relates to a lubricating oil level warning device used in a lubricating oil tank of a medium-speed propulsion engine, which simplifies the device by enabling use.

중속 추진용 엔진의 경우 윤활유 탱크에 설치되는 윤활유 높이 경고 장치를 엔진외부에 설치할 경우 공간상 제약으로 인해 엔진 옆 부분에 설치가 쉽지 않고, 엔진 앞부분이나 뒷부분에 설치되도록 설계시 실제 선박 운항시 롤링(rolling)현상 이 발생하여 정확한 윤활유 레벨을 감지하지 못할뿐더러 선박의 배관 및 축계 시스 템과의 간섭으로 인해 유지 보수가 쉽지 않다는 문제점이 있었다.In case of medium speed propulsion engine, when installing the oil level warning device installed in the lubricating oil tank outside of the engine, it is not easy to install on the side of the engine due to space limitations. Due to rolling phenomena, accurate lubricant levels were not detected, and maintenance was not easy due to interference with ship piping and shaft systems.

또한, 도 1 은 종래에 사용된 외부 돌출형 윤활유 높이 경고장치 개략도로서, 일부는 윤활탱크 내부에 삽입되고, 일부는 외부에 설치되는 구조로 되어있으며, 탱크 내부에 삽입된 부분에는 공기통(1)이 공기통 결합부(2)에 힌지 결합되어 윤활유 양에 따라 상기 결합부를 중심으로 상기 공기통이 작동함으로써 레벨을 감지하게 된다. 그러나 이러한 장치는 레벨 값은 정확하나, 엔진 외부로 돌출되는 부분 때문에 설치시 야드 설치물과 간섭으로 인해 설치에 많은 제약이 따른다는 문제점이 있었다.In addition, Figure 1 is a schematic diagram of an external protrusion type lubricating oil level warning device used in the prior art, a part of which is inserted into the lubrication tank, a part of the structure is installed on the outside, the air cylinder (1) in the part inserted into the tank The reservoir is hinged to the coupling portion (2) is to sense the level by operating the reservoir around the coupling portion in accordance with the amount of lubricating oil. However, such a device has a problem that the level value is correct, but the installation is limited due to interference with the yard installation when installed because of the protruding portion outside the engine.

또한, 도 2 는 종래에 사용된 내부 설치용 윤활유 높이 경고장치 개략도로서, 엔진 내부에 설치되어 엔진 외부로 설치되지 않고, 정확한 레벨 값을 측정할 수 있으나, 케이블이 윤활유와 접촉되는 것을 방지하기 위하여 케이블 보호용 커버파이프(3) 및 클렘프(4)등의 별도의 장치가 필요하여 추가적인 장비 설치로 인해 비용 상승 및 유지 보수가 어렵다는 문제점이 있었다.
In addition, Figure 2 is a schematic diagram of the internal installation of the lubricating oil level warning device used in the prior art, it is installed inside the engine is not installed outside the engine, it is possible to measure the exact level value, but to prevent the cable from contacting the lubricating oil There is a problem in that it is difficult to increase the cost and maintenance due to the installation of additional equipment, such as a separate cover such as the protective cover pipe (3) and the clamp (4).
