Abstract

<P>PROBLEM TO BE SOLVED: To provide an earthquake-proof fire protecting and active drinking water tank for securing fire service water and drinking water for local residents without using motive power in natural disasters including earthquake. <P>SOLUTION: Normally, running water is fed through an emergency shut-off valve 3 between a water main pipe 1 and a water tank 5 to a water tank 5, and then it is returned to the emergency shut-off valve 3 and fed to the main pipe. When the main pipe 1 is broken in emergency and water pressure drops, the emergency shut-off valve 3 is operated to secure water in the water tank 5 while preventing its flow-out. When a water supply pipe 4 between the emergency shut-off valve 3 and the water tank 5 or a drain pipe 10 between the water tank 5 and the emergency shut-off valve 3 is broken, a siphon phenomenon preventing air hole 11 provided in the highest portion of a water feed pipe 6 in the water tank 5 or of a drain pipe 9 in the water tank 5 prevents the flow-out of the water. Branch pipes 8 are provided at any places for the water feed pipe 6 in the water tank 5 for spraying feed water into the water tank 5 at every corner to serve active driving water. <P>COPYRIGHT: (C)2007,JPO&INPIT

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 valve 3 by the gate valve 2, passes through the water pipe 4, and is sent to the water pipe 6 inside the water tank 5. Water is stopped at the tip of the water supply pipe 6 by the Mekura cap 7. A small diameter branch pipe 8 is provided in the water supply pipe 6, and water is jetted from the branch pipe 8. The jetted water reaches every corner of the water tank 5 as live water. The water stored in the water tank 5 is discharged to the outside of the water tank 9 by the drain pipe 9 in the water tank 5 and sent to the main pipe 1 through the drain pipe 10. As shown in FIG. 5, when the main pipe 1 is damaged due to an earthquake, the water pressure is lowered, the emergency shut-off valve 3 is activated, and the water in the water tank 5 is secured. When the water supply pipe 4 and the drain pipe 10 between the emergency shut-off valve 3 and the water tank 5 are damaged, the water in the water tank 5 flows out, but the air hole is located at the highest position of the water supply pipe 6 and the drain pipe 9 in the water tank 5. 11 is provided. When water in the water tank 5 flows out, the air holes 11 act as siphon phenomenon preventing air holes. Since the gap between the opening of the air hole and the inner wall of the water tank 5 is very small, the water in the water tank 5 only flows out a little.

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.

発明が解決しようとする課題Problems to be solved by the invention

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 pipes 1, 4 and 10 outside the water tank 5 are damaged, the water in the water tank 5 is prevented from flowing out.

課題を解決する手段Means to solve the problem

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 main pipe 1 is damaged, the emergency shut-off valve 3 is actuated due to a decrease in water pressure, and the outflow of water in the water storage tank 5 is prevented. When the pipes 4 and 10 are damaged, 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, and the water flowing out automatically stops when the water level falls below 11.
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)

強い地震発生時地域住民の消火用水と活性飲料水を供給する水槽である。平常時水道水は、仕切弁２により本管１を通り緊急遮断弁３を通り送水管４を通り水槽５に導入され排水管９、１０を通り本管１に流される。
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. 飲料水として供給するには活水でなければならぬ。そのため水槽５内の送水管６には分岐管８を設け水槽５内の隅々に行き亘るように送水を噴出させる水槽５内の水全てを活性飲料水として安全に供給するものである。It must be live water to be supplied as drinking water. For this reason, a branch pipe 8 is provided in the water supply pipe 6 in the water tank 5, and all the water in the water tank 5 from which water supply is ejected so as to reach every corner of the water tank 5 is safely supplied as active drinking water.
