Abstract
Description
本発明は地震などの災害時に地域住民の安全に寄与するものであり、消化用水及び活性飲料水を確保するものである。
平常時水道本管1の水道水は仕切弁2によって緊急遮断弁3に送られ送水管4を通り水槽5の内部の送水管6に送られる。送水管6の先端はメクラキャプ7によって水は止められる。送水管6には小径分岐管8を設け水は分岐管8より噴射される。噴射された水は水槽5内の隅々まで活水として行き亘る。水槽5に貯められた水は水槽5内の排水管9により水槽9の外部に排出され排水管10を通り本管1に送られる。図5の通り本管1が地震のため破損されたら水圧が下がり緊急遮断弁3が作動し水槽5内の水は確保される。又緊急遮断弁3と水槽5の間の送水管4と排水管10が破損した場合、水槽5内の水が流出するが水槽5内の送水管6と排水管9の最も高い位置に空気孔11を設ける。水槽5内の水が流出した時はこの空気孔11はサイホン現象防止空気孔として作用する。この空気孔の開口部と水槽5の内壁との間隙は僅少であるため水槽5内の水は少々流出するだけである。The present invention contributes to the safety of local residents in the event of a disaster such as an earthquake, and ensures digestion water and active drinking water.
The tap water of the normal water main 1 is sent to the emergency shut-off
実用新案登録番号第3031701号
この実用新案は縦型貯水タンク本体の内側下部に給水管の先端の水噴射口をタンク本体の内側に沿って接線方向に位置させて渦流をタンク下部から上部へと生じさせているがタンクの内径が大きく、長さが長ければその渦流は上部へは及び難いものであり、活水としては難点がある。Utility Model Registration No. 3031701 This utility model has a water jet at the tip of the water supply pipe located at the inner lower part of the vertical water tank main body in a tangential direction along the inner side of the tank main body so that the vortex flows from the lower part of the tank to the upper part. Although it is generated, if the inner diameter of the tank is large and the length is long, the vortex flow hardly reaches the upper part, and there is a difficulty as active water.
本発明は動力を使わず水槽5内の水が消火用水のみならず活水飲料として安心して完全に確保されるものである。又、強い地震発生の場合水槽5の外部の配管1、4、10が破損した場合水槽5内の水の流出を防ぐものである。In the present invention, the power in the water tank 5 is completely ensured as active water drinks as well as fire extinguishing water without using power. Further, in the event of a strong earthquake, when the
上記課題を達成すべく本発明に至った
水槽5内の送水管6には小径の分岐管8を随所に設け送水が水槽5内に噴射される。噴射された水は活水として貯められている。又強い地震が発生し本管1が破損した場合、水圧の低下により緊急遮断弁3が作動し貯水槽5内の水の流出が防止されるものである。又配管4、10が破損した場合は水槽5内の送水管6と排水管9の最高部にサイホン現象防止空気孔11を設け水位が11より下がった時流出する水は自動的に停止する。
このように水槽5内の水は配管4、10が破損された時、自動的に流出が防止される二段構えの流出防止策を設けるものである。In order to achieve the above object, the water pipe 6 in the water tank 5 that has reached the present invention is provided with small-diameter branch pipes 8 at various places, and water is sprayed into the water tank 5. The injected water is stored as live water. In addition, when a strong earthquake occurs and the
Thus, the water in the water tank 5 is provided with a two-stage outflow prevention measure that automatically prevents the outflow when the pipes 4 and 10 are damaged.

Claims (2)
緊急遮断弁3の上流の送水管1が破損した時水圧の低下により緊急遮断弁3が作動し水槽5からの水の流出を防止するものである。
尚、緊急遮断弁3と水槽5の間の送水管4と排水管10が破損した場合は水槽5内の水の流出を最小限に防止する。
水槽5内の送水管6と排水管9の最高部にサイホン現象防止空気孔11を設ける。水槽5内の水位がこの空気孔11より下がった場合、それ以上の水の流出は自動的に阻止される。
このサイホン現象防止空気孔11の開口部と水槽5の内壁との間隙は僅少であるため、水の流出は微々たるものである。
このように本管1が破損した場合は緊急遮断弁3により水槽5内の水の流出が阻止され、尚緊急遮断弁3と水槽5との間の送水管4と排水管10が破損した場合は水槽5内の送水管6と排水管9の最高部に設けた空気孔11がサイホン現象防止孔として作用し水槽1内の水の流出を最小限に防止される。
このように二段構えの流出防止策を設けることを特徴とする水槽である。This tank supplies fire water and active drinking water for local residents when a strong earthquake occurs. Normal tap water is introduced into the water tank 5 through the main pipe 1, through the emergency shut-off valve 3, through the water supply pipe 4, and into the water tank 5 through the drain pipes 9 and 10 by the gate valve 2.
When the water supply pipe 1 upstream of the emergency shut-off valve 3 is damaged, the emergency shut-off valve 3 is actuated by a drop in water pressure to prevent water from flowing out of the water tank 5.
In addition, when the water supply pipe | tube 4 and the drain pipe 10 between the emergency shutoff valve 3 and the water tank 5 are damaged, the outflow of the water in the water tank 5 is prevented to the minimum.
A siphon phenomenon preventing air hole 11 is provided at the highest part of the water supply pipe 6 and the drain pipe 9 in the water tank 5. When the water level in the water tank 5 falls below the air hole 11, further outflow of water is automatically prevented.
Since the gap between the opening of the siphon phenomenon preventing air hole 11 and the inner wall of the water tank 5 is very small, the outflow of water is insignificant.
In this way, when the main pipe 1 is damaged, the emergency shutoff valve 3 prevents water from flowing into the water tank 5, and the water supply pipe 4 and the drain pipe 10 between the emergency shutoff valve 3 and the water tank 5 are damaged. The air hole 11 provided in the highest part of the water pipe 6 and the drain pipe 9 in the water tank 5 acts as a siphon phenomenon prevention hole, and the outflow of water in the water tank 1 is prevented to the minimum.
Thus, it is a water tank characterized by providing a two-stage outflow prevention measure.
