BACKGROUND OF THE INVENTION
The present invention relates to a mass measuring unit for measuring the mass of the fire extinguishing agent Bonn base installed in, for example, multi-storey car park.
[0002]
[Prior art]
For example, a multistory parking lot or the like is provided with a large number of cylinders filled with a fire extinguisher and housed in a cabinet. As such extinguishing agents, carbon dioxide and parogen compounds are generally used, but if they are leaking, their functions may not be exhibited when a fire breaks out. It is required by law to measure the mass and check whether a predetermined amount of extinguishing agent is filled.
[0003]
In measuring the mass of such a cylinder, conventionally, the cylinder was suspended and measured with a platform scale or the like (see, for example, Japanese Utility Model Laid-Open Nos. 1-1131126 and 3-49864). However, since the mass of this cylinder reaches 100 kg or more (for example, 130 kg), there are various problems such as a large facility for hanging and a lot of time for mass measurement.
[0004]
In order to solve such a problem, for example, in JP-A-6-241875, a load cell is installed at a position in contact with the bottom surface of a fire extinguisher storage container (cylinder), and the mass of the fire extinguisher storage container is constantly measured. An invention to measure is disclosed (prior art 1).
In addition, in Japanese Utility Model Publication No. 7-4040, a starting gas container (cylinder) is placed on an electronic platform scale, and the mass of the starting gas container is constantly detected to monitor the decrease in the starting gas. An apparatus is disclosed (prior art 2).
[0005]
