明 細 書 消火器 技術分野 Description Fire extinguisher Technical field
この允明は、 投下式の消火器のシステムに関するものであり、 消火器 本体の落下の衝 を利用して、 消化剤の噴財が開始される。 噴射ノズル の含まれる消火器頭部は回転式になっており、 地上に投下された消火器 本体から噴射される消化剤は、 常に上方に向けて噴射され、 効率の^い 消火活動を实施得る。 This Yunmei relates to a fire-extinguishing fire extinguisher system, in which the fire extinguisher is started using the impact of the fire extinguisher itself. The fire extinguisher head, which contains the spray nozzle, is of a rotary type, and the fire extinguisher that has been dropped on the ground is extinguished from the fire extinguisher body, which is always sprayed upwards, enabling efficient fire fighting. .
背景技術 Background art
消火作業が困難な火災、 例えば山火事の消火作業に^して、 ヘリコブ 夕一等を山火事の現場上空に飛ばし、 そこから消化剤を空中散布して鎮 火せしめることが一般的に行われている。 It is common practice to extinguish a fire that is difficult to extinguish, such as a wildfire, by flying a helicopter over the wildfire site and spraying a fire extinguisher in the air to extinguish the fire. ing.
しかし、 従来、 消化剤を空中散布する場合に、 消化剤は空中で拡散さ れるので、 実 こ発火している地点に到達する消化剤の量は空中散布さ れた消化剤の全体量に比校すると、 非常に少なく、 そのためへリコプ夕 一等による従来の空中散布では、 消化剤有効消费効率が非常に低かった 。 特に、 山火事の現場に強風が吹いている場合にはその傾向が強い。 また、 笫 7図で示すように、 山火事の^に上空のヘリコプター Hから 散布された消化剤 H Sは樹木 Tの上部に到達してその火を消化すること はできても、 比校的下方の部分 （レベル Lよりも下方の部分） 、 例えば 路面 Gに繁茂している下草 Uには到達せず、 下草 Uの火を消すことがで きない。 そのため、 樹木 Tの火を消した後にも、 下草 U内に残った火種 により再出火するおそれがあった。 本発明は上記した従来技術の問題点に鑑みて提案されたものであり、 長距離を隔てた発火地点に消化剤を確実に且つ効率] ¾く散布することが できる消火器を提供することを目的としている。 明の開示 However, conventionally, when the digestive is sprayed in the air, the amount of the digestive reaching the point where the fire actually ignites is smaller than the total amount of the digestive sprayed in the air, because the digestive is diffused in the air. At school, it was very low, and the conventional aerial spraying by Helicopter et al. Showed very low efficiency of effective digestive consumption. This is especially true when strong winds are blowing at the site of a forest fire. Also, as shown in Fig. 7, fire extinguisher HS sprayed from the helicopter H over the forest fire at the top of the tree fire reaches the upper part of tree T and can extinguish the fire. (The part below the level L), for example, does not reach the undergrowth U overgrown on the road surface G, and the fire of the undergrowth U cannot be extinguished. Therefore, even after the fire of tree T was extinguished, there was a risk that a fire would be reignited due to the fire remaining in the undergrowth U. The present invention has been proposed in view of the above-described problems of the related art, and provides a fire extinguisher that can surely and efficiently spray a fire extinguisher to an ignition point that is separated over a long distance. The purpose is. Ming disclosure
