Description

축압식 소화기의 상시 압력 감지장치Constant pressure sensor of accumulator fire extinguisher

본 발명은 소화기의 압력을 감지하는 장치에 관한 것으로, 더욱 상세하게는 축압식 소화기의 압력계를 이미지센서를 이용하여 촬영하여 소화기의 내의 압력을 감지하고, 감지된 압력이 설정 압력 이하로 하강하게 되면 이를 외부의 관리자 등에게 통보할 수 있는 축압식 소화기의 상시 압력 감지장치에 관한 것이다. The present invention relates to a device for detecting the pressure of the fire extinguisher, and more particularly, to detect the pressure in the fire extinguisher by photographing the pressure gauge of the accumulator using an image sensor, and when the detected pressure falls below the set pressure, The present invention relates to a pressure sensor for accumulating fire extinguishers that can notify external managers.

일반적으로 소화기는 본체 내에 분말약제와 기체가 압축되어 있다가 사용자가 손잡이를 눌러 마개가 열리면 압축기체가 분말약제를 밖으로 밀어내며 이렇게 밀려나온 분말약제가 화염 위에 뿌려져서 화재가 진압 된다. In general, a fire extinguisher is compressed powder and gas in the body, and when the user presses the handle to open the stopper, the compressor body pushes out the powdered medicine, and the powdered medicine is sprayed onto the flame to extinguish the fire.

따라서 소화기가 정상적으로 작동되기 위해서는 소화기 본체 내의 압력이 일정 압력(7~9.8㎏/㎠)으로 유지되어야 한다. 그러나 소화기 본체 내에 압력을 충분히 충전한 경우에도 환경의 변화와 시간이 지남에 따라 그 압력이 점차 감소되어 소화기가 정상적으로 작동할 수 있는 압력 이하로 내려 갈 수 있다.Therefore, in order for a fire extinguisher to operate normally, the pressure in the fire extinguisher main body must be maintained at a constant pressure (7 to 9.8 kg / cm 2). However, even when the pressure is sufficiently charged in the body of the fire extinguisher, the pressure gradually decreases as the environment changes and over time, so that the fire extinguisher can be lowered to a pressure that can be normally operated.

이러한 압력의 변화를 점검할 수 있도록 소화기에는 압력게이지가 설치되어 있으나, 이에 무관심하거나 점검을 소흘이 하는 경우가 많고 때로는 아주 방치되는 경우도 많아 정작 화재시 사용하고자 할 때 적정 분사 압력으로 소화약제를 분출하지 못하여 초기 화재진압에 실패하는 경우가 많다.The pressure gauge is installed in the fire extinguisher so that the pressure change can be checked. However, the fire extinguisher is often indifferent or often overhauled and sometimes very neglected. In many cases, early fire suppression fails due to failure to erupt.

특히 소화기가 바닥에 설치되어 관리자가 근접해서 허리를 굽혀 일일이 압력게이지를 관찰해야 하거나, 고층 건물, 대형 공장에서는 관리자가 일일이 소화기의 적정 압력을 관찰하기 위해서는 많은 노력과 시간이 소요되므로 축압식 소화기의 압력 이상 유무를 점검하는데 많은 어려움이 따르고 있다.In particular, the fire extinguisher is installed on the floor, and the manager must bend closely to observe the pressure gauge.In high-rise buildings and large factories, it is necessary for the manager to observe the pressure of the fire extinguisher. There are many difficulties in checking for abnormalities.

또한 기존의 축압식 소화기의 압력 감시장치에 관련된 특허들은 소화기의 국제시험인증규격과 연관된 소화기 형상을 변화시키는 기술로서 실용화되지 못하는 문제점을 가지고 있다.In addition, patents related to the pressure monitoring device of the accumulator extinguisher has a problem that cannot be put to practical use as a technology for changing the extinguisher shape associated with the international test certification standard of the extinguisher.

The present invention is to solve the above problems, the present invention is to detect the pressure in the fire extinguisher by photographing the pressure gauge of the accumulator fire extinguisher with an image sensor, and when the detected pressure falls below the set pressure is automatically It is to provide a constant pressure sensing device of a pressure extinguisher that can notify the manager.
