本考案は消火剤の収容ボンベの下部に放射圧力
減少装置を具備する自動消火装置に関する。[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an automatic fire extinguishing system that is equipped with a radiation pressure reduction device at the bottom of a cylinder containing a fire extinguishing agent.

なつている（実開昭57−134057号）。
The applicant has previously developed a ceiling-mounted automatic fire extinguishing system that is equipped with a spray nozzle at the bottom of a fire extinguishing agent storage cylinder. When the plate senses the temperature of a fire, the welded low-temperature molten metal melts, and the pressure of the extinguishing agent in the cylinder causes the heat-sensitive plate to detach from the injection nozzle, causing the extinguishing agent to be sprayed downward. 57-134057).
この種の自動消火装置Ａは第１図に示すように
通常２〜2.5ｍの高さの普通には天井面に設置し、
真上から消火剤を直接火元Ｂに放射して消火する
方式であるため、非常に効果的な直接消火方式で
あることが実証されている。
This type of automatic fire extinguishing system A is usually installed on the ceiling at a height of 2 to 2.5 m, as shown in Figure 1.
Since the fire extinguishing agent is emitted directly from above to the fire source B to extinguish the fire, it has been proven to be a very effective direct fire extinguishing method.
しかし第２図に示すように天井面が低いとか障
害物等があつて自動消火装置Ａの設置高さが例え

であつた。 However, as shown in Figure 2, if the ceiling is low or there are obstacles, and the installation height of automatic fire extinguishing system A is very low, for example 0.5 to 1.0 m, the force of the fire extinguishing agent will be reduced. Because it is too strong, if fire source B is oil, the oil etc. will be scattered around, creating a dangerous situation in many cases, and it is virtually difficult to install automatic fire extinguishing systems in such places. It was hot.

The present invention was developed to solve these problems, and is an automatic fire extinguishing system that is equipped with an injection nozzle for ejecting extinguishing agent at the bottom, and a heat sensing plate is welded to the injection nozzle with low-temperature molten metal. The intended purpose is achieved by providing an automatic fire extinguishing system characterized by providing a radiation pressure reduction device that also serves as a protective cover around the injection nozzle.

In the present invention, the radiation pressure reducing device (deflector), which also serves as a protective cover, is installed around the fire extinguisher injection nozzle, and has the functions of both preventing the scattering of dangerous substances such as oil and protecting the sensing part. Usually, it is constructed in the form of an integral cover, and may be fixed to the fire extinguisher body or the injection nozzle, but it can also be detachably attached using screws or the like. As the above-mentioned deflector, a bottomed cylindrical body such as a cylindrical or prismatic cylinder made of a perforated plate or a mesh plate having a large number of holes in the bottom and side surfaces is advantageously used.
