PUMP WATER SUCTION DEVICE FOR SNOW ACCUMULATION FROZEN WATER TANK
To provide a novel quick fire pump water suction method of a snow accumulation frozen water storage tank and a novel water suction device in order to solve a problem that initial fire extinguishing activities are delayed because it takes time to remove snow accumulation frozen ice when a fire engine uses an emergency snow accumulation frozen water storage tank in an event of a fire, since 30 cm to 40 cm of ice forms on a water surface of a water storage pond and an outdoor fire prevention water tank in a severe cold region.SOLUTION: It has been reported that, even if there is an ice layer on a surface of a snow accumulation frozen water storage pond and a frozen fire prevention water tank, there is water in the water tank. A solution is means in which if a cylindrical water suction tube is installed in the water tank while penetrating a surface frozen ice layer, and a cold-resistant long tube bag with a valve is inserted into a water suction pipe to inject high-pressure air, natural inundation in the pipe can be prevent for a long time due to full expansion of a bag inside the pipe, and if a water suction hose is inserted into a cavity formed by removing air from the tube when a fire engine uses a snow accumulation frozen water storage tank, water can be easily sucked from the snow accumulation frozen water storage tank using a pump so as to extinguish the fire.SELECTED DRAWING: Figure 3
【課題】厳寒地方の貯水池、屋外防火水槽の水面には30ｃｍ〜40ｃｍの氷が張る為、火災発生時 消防車が緊急積雪凍結貯水槽を使用する場合、積雪凍結氷除去作業に時間が掛かる為 初期消火活動が遅れる課題があった。現在に至っても、迅速に積雪凍結貯水槽の消防ポンプ吸水方法、吸水装置等は開発されてないのが実状である。【解決手段】積雪凍結貯水池、凍結防火水槽は、表面に氷層があっても、水槽内には貯水のあることが報告されている。解決手段は表面凍結氷層を貫通して円筒吸水管を水槽内に設置して更に吸水管内にバルブ付耐寒性長チューブ袋を挿入して高圧空気を注入すれば、袋体は管内満杯に膨張して管内自然浸水を長期間防止ができる、消防車が積雪凍結貯水槽使用の場合、チューブ空気を抜いた空洞内に吸水ホースを挿入すれば容易に積雪凍結貯水槽からポンプ吸水ができて火災消火ができる手段である。【選択図】 図３
