The emergency power supply driven pump is normally placed in operation to supply water. If the emergency power supply driven pump becomes unable to operate, the gate vale is opened or the three-way valve is switched to a side for sucking the water of the water source into the hand pump, and the three-way valve fitted to the confluence pipe is changed from the hand pump to a water supply port side of the temporary toilet so as to supply water through backup operation by the hand pump.

Description

本発明は、災害時の非常電源駆動ポンプをバックアップする仮設トイレ用給水ポンプシステムに関する。  The present invention relates to a water supply pump system for a temporary toilet that backs up an emergency power supply pump in a disaster.

東北関東大震災以降、災害時の生活用水を確保しようとする機運がより一層高まっている。特に、停電時の仮設トイレへの給水と、その対応が大きな課題となっている。これの公知例として、文献1、文献2がある。  Since the Great Tohoku Kanto Earthquake, there has been a further increase in momentum to secure water for daily use in the event of a disaster. In particular, water supply to temporary toilets in the event of a power outage and the response are major issues. Known examples of this include Document 1 and Document 2.

文献1のマンホール設置式可搬手押しポンプは、防災用水としての貯水槽マンホール上に可搬手押しポンプを設置し、前記マンホールにホース(吸込み管)を通す穴を開け、水源の水を、前記ホースを介して前記手押しポンプにより吸い上げて災害時に無電力で給水するための手押しポンプ、マンホール、可搬手段である二輪車の構造、形状が開示されている。  The manhole-installable portable hand pump of Document 1 has a portable hand-pump installed on a water tank manhole as water for disaster prevention, and a hole for passing a hose (suction pipe) is opened in the manhole, and water from the water source is supplied to the manhole. The structure and shape of a two-wheeled vehicle that is a hand pump, a manhole, and a portable means for sucking up by the hand pump through the air and supplying water without power during a disaster is disclosed.

また文献2の仮設トイレは、便器と、この便器に流す洗浄水を蓄える貯水タンクとが一体となり、人力ポンプと電動ポンプを併設し、貯水タンクの洗浄水を前記併設したポンプにより便器に送水して洗浄することが開示されている。加えて、人力ポンプの起動用のぺダルが踏まれた場合、これと連動して電動ポンプも運転し、更に、電動ポンプの起動スイッチがあり、これの操作により運転ができ併用されることが開示されている。尚、災害時は、集団で避難するため仮設トイレが複数台併設して設置されている。  The temporary toilet of Document 2 is a combination of a toilet and a water storage tank for storing wash water to be passed to the toilet, and is equipped with a human-powered pump and an electric pump, and the wash water in the water storage tank is sent to the toilet by the above-described pump. Cleaning is disclosed. In addition, when a pedal for starting a human power pump is stepped on, the electric pump is also operated in conjunction with this, and there is an electric pump start switch, which can be operated and used together. It is disclosed. In the event of a disaster, multiple temporary toilets are installed side by side to evacuate as a group.

実用新案文献1Utility model document 1

実願2012−3781公報 マンホール設置式可搬手押しポンプJapanese Patent Application No. 2012-3781 Manhole-installable portable hand pump

しかしながら、文献1のマンホール設置式可搬手押しポンプおいては、電動ポンプと併設して使用することが開示されていない。文献2の仮設トイレにおいては、併設された人力ポンプと電動ポンプについて併用して運転する記載はあるが、電動ポンプがダウンした際に人力ポンプでバックアップすることが開示されておらず、その重要性が認識されていない。前記併設ポンプは、便器を洗浄するためのものであり仮設トイレが、人力ポンプと電動ポンプが故障して使用できなくなっても、隣の仮設トイレが使用できるので優先して電動ポンプを使用し、これが故障した時人力ポンプを使用するというシステムの必要性がないためである。
そこで、本発明の目的は、災害時(停電時)の仮設トイレ群へ停電時も安定して給水が可能なポンプは非常電源駆動ポンプとし、この非常電源ポンプがダウンした時のバックアップポンプとして人力で操作の可能な手押しポンプとで構成した仮設トイレ用給水システムを提供することにある。
ところで、本発明の仮設トイレ群用給水システムは災害用が主用途であるため、非常電源駆動ポンプの運転を優先して長時間運転するようにし、バックアップ用である手押しポンプは初めの非常電源駆動ポンプの呼び水、吸込み管の空気除去及び満水を行う場合に運転を制限して使用時間を減らし(耐用使用期間を向上させる)非常電源駆動ポンプダウン時のバックアップに備えている。
更に、本発明の仮設トイレ群用給水システムは災害用が主用途であるため、万能形が求められる。本システムに使用するポンプは、汎用性が高く一般に広く用いられている遠心ポンプを用いる。特に、遠心ポンプを用いると吸込み運転において次に示す問題があり、これを解消する必要がある。
1)ポンプと吸込み管の空気を水と置換し呼び水を行う。複雑な吸込み管はこれが困難。
2)更に、従来は、上記1)の問題を解消するのが困難なため複数ポンプの吸込み側を合 流させることを回避していた。
However, the manhole-installed portable hand pump of Document 1 does not disclose use in combination with an electric pump. In the temporary toilet of Document 2, there is a description that the combined human power pump and electric pump are operated in combination, but it is not disclosed that the electric pump backs up when the electric pump goes down. Is not recognized. The ancillary pump is for cleaning the toilet bowl, and even if the temporary toilet cannot be used due to failure of the human-powered pump and the electric pump, the adjacent temporary toilet can be used, so the electric pump is preferentially used, This is because there is no need for a system that uses a human-powered pump when it fails.
Therefore, an object of the present invention is to use an emergency power supply pump as a pump that can stably supply water to a temporary toilet group at the time of a disaster (at the time of a power failure), and as a backup pump when this emergency power pump goes down. It is in providing the water supply system for temporary toilets comprised with the hand pump which can be operated by.
By the way, the water supply system for the temporary toilet group according to the present invention is mainly used for disasters. Therefore, the operation of the emergency power supply pump is prioritized for a long time, and the hand pump used for backup is the first emergency power supply drive. When pump priming, suction pipe air removal and full water are used, the operation is limited to reduce the usage time (to improve the service life) and to prepare for backup when the emergency power supply pump is down.
Furthermore, since the water supply system for the temporary toilet group of the present invention is mainly used for disasters, a universal type is required. The pump used in this system is a centrifugal pump that is highly versatile and generally widely used. In particular, when a centrifugal pump is used, there is the following problem in the suction operation, which needs to be solved.
1) Replace the air in the pump and suction pipe with water and perform priming. This is difficult for complex suction pipes.
2) Further, conventionally, since it is difficult to solve the problem 1), it has been avoided to join the suction sides of a plurality of pumps.

上記目的を達成するために本発明の一実施形態は、ポンプより下位にある水源からの水を吸い込み仮設トイレの給水口に送水する呼び水手段を備えた非常電源駆動ポンプと、前記水源からの水を吸込み仮設トイレの給水口に送水する手押しポンプと、前記水源からの水を前記ポンプ共通に吸上げる先端にフート弁を取り付けた吸込み管と、入口を該吸込み管に接続し途中に仕切弁又は三方弁を取り付け、一方を前記非常電源駆動ポンプ吸い込み口へ他方を前記手押しポンプ吸い込み口へ連結する吸込み分岐管と、前記両ポンプの吐出し口を合流する三方弁を取り付けた合流管と、前記三方弁の仮設トイレ側と接続する仮設トイレに送水する送水配管とで構成した仮設トイレ用給水システムにおいて、通常時は前記吸込み管に取り付けた仕切弁を閉鎖し、又は三方弁を水源の水が前記非常電源駆動ポンプへ吸込まれる側に切り替え、前記合流管に取り付けた三方弁を前記非常電源駆動ポンプから仮設トイレの給水口側へ切り替えて、前記非常電源駆動ポンプを運転して給水し、該非常電源駆動ポンプが運転不能となった場合は、前記吸込み分岐管に取り付けた仕切弁を開放し、又は前記三方弁を水源の水を前記手押しポンプに吸込まれる側に切り替え、前記合流管に取り付けた三方弁を前記手押しポンプから仮設トイレの給水口側へ切り替えて、手押しポンプによりバックアップ運転して給水するようにした停電時も安定して給水が可能な仮設トイレ群用給水システムである。
尚、非常電源駆動ポンプには遠心ポンプを用いたものである。

以下、本発明の実施形態について図1〜図4により説明する。
先ず第1の実施形態について説明する。図1は第1〜第6の実施態様に共通の災害用仮設トイレ群の送水に適用した仮設トイレ用給水システムの系統図を示している。1は水源であり例えば避難先が学校であればプール、公園等であれば防火.防災用水槽等である。そして、この水源は設置されるポンプよりは下位にあることが多い。この場合、ポンプと水源との距離は高さで5〜6m以内とするのが望ましい。2は先端にフート弁19を取り付けた吸い込み管、3は入口を前記吸い込み管と連結し、出口側の一方を非常電源駆動ポンプ(以下ポンプと略して呼ぶ)5の吸込み口5aに接続し、他方を手押しポンプ6の吸込み口6aと接続する途中に三方弁4、又は仕切弁4−1(図示は三方弁で示しているが、仕切弁4−1でも良い)を取り付けた吸込み分岐管、7は一方を前記ポンプ5の吐出し口5bと接続し、他方を前記手押しポンプ6の吐出し口6bと接続する途中に三方弁8を取り付けた合流管、9は前記三方弁の一方と接続し仮設トイレ群18と連結した横引き配管13の一方の接続口13aと接続する送水管、14、15はそれぞれ前記横引き配管13に接続する貯留槽及び仕切弁、16は前記横引き配管13(接続口13b)と接続し下水管17と接続して滞留した仮設用トイレ群使用後の汚水及び汚物を給水と一緒に送水するする送水管、20は前記ポンプのモータ22に電力S20を供給する非常電源装置であり、一般に石油系を燃料とする発電機を用いる。尚、前述の三方弁4又は仕切弁4−1はポンプへの空気噛み込み防止を考慮すると極力手押しポンプ側に取り付けるのが望ましい。このように構成した仮設トイレ用給水システムの要点について説明する。
前述したポンプ5は、遠心ポンプを採用する。その理由は、自吸式ポンプもあるが吸込み側が分岐し且つ、三方弁又は仕切弁が取り付けられており完全な自吸に不安があり、これの対処が難しく、後で述べる手押しポンプの採用とこれによる吸込み管、分岐管、ポンプ内の呼び水、空気除去、満水が十分にできることが明らかなためでる。そして、ポンプ5には呼び水手段10が備わっている。この呼び水手段10は呼び水じょうご又はタンク12(手押しポンプ運転時に空気を吸い込まない程度の容量であれば良い。)と仕切弁11から成る。
手押しポンプ6は、本システムにおいて、非常電源ダウン時のポンプバックアップとして不可欠であるばかりでなく前述した吸込み管、分岐管、ポンプ内の呼び水、空気除去、満水機能を果たす重要な機器となっている。よって、前述したように優先してポンプを運転し手押しポンプは前記ポンプの呼び水、吸込み管の空気除去及び満水時の運転に制限して寿命の長時間化を図り、前記ポンプダウン時のバックアップ運転に備えられるようにする。
Hereinafter, embodiments of the present invention will be described with reference to FIGS.
First, the first embodiment will be described. FIG. 1: has shown the systematic diagram of the temporary toilet water supply system applied to the water supply of the disaster temporary toilet group common to the 1st-6th embodiment. 1 is a water source. For example, if the evacuation destination is a school, it is a pool, and if it is a park, fire prevention. It is a tank for disaster prevention. And this water source is often lower than the installed pump. In this case, the distance between the pump and the water source is preferably 5 to 6 m or less in height. 2 is a suction pipe having a foot valve 19 attached to the tip, 3 is an inlet connected to the suction pipe, and one outlet side is connected to a suction port 5a of an emergency power supply pump (hereinafter abbreviated as a pump) 5; A suction branch pipe to which a three-way valve 4 or a gate valve 4-1 (shown as a three-way valve is shown, but may be a gate valve 4-1) is attached in the middle of connecting the other to the suction port 6a of the hand pump 6. 7 is connected to the discharge port 5b of the pump 5, and the other is connected to the discharge port 6b of the hand pump 6. The junction pipe has a three-way valve 8 attached, and 9 is connected to one of the three-way valves. A water supply pipe connected to one connection port 13a of the horizontal pulling pipe 13 connected to the temporary toilet group 18, 14 and 15 are respectively a storage tank and a gate valve connected to the horizontal pulling pipe 13, and 16 is the horizontal pulling pipe 13. (Connecting port 13b) A water supply pipe 20 for supplying sewage and filth after use with a temporary toilet group staying connected to the water pipe 17 together with water supply is an emergency power supply device for supplying electric power S20 to the motor 22 of the pump. A generator using the system as fuel is used. The above-described three-way valve 4 or gate valve 4-1 is preferably attached to the hand-pumped pump side as much as possible in consideration of prevention of air entrainment into the pump. The main points of the water supply system for temporary toilets configured as described above will be described.
The pump 5 described above employs a centrifugal pump. The reason for this is that although there is a self-priming pump, the suction side is branched and a three-way valve or gate valve is attached, and there is concern about complete self-priming, which is difficult to deal with. This is because it is clear that suction pipes, branch pipes, priming water in the pump, air removal, and full water can be sufficiently obtained. The pump 5 includes a priming means 10. The priming means 10 comprises a priming funnel or tank 12 (which may be of a capacity that does not suck air when the hand pump is operated) and a gate valve 11.
In this system, the hand pump 6 is not only indispensable as a pump backup at the time of emergency power down, but also an important device that performs the above-described suction pipe, branch pipe, priming water in the pump, air removal, and full water function. . Therefore, the pump is operated preferentially as described above, and the hand pump is limited to the pump priming water, the suction pipe air removal and the operation at the time of full water to extend the life, and the backup operation when the pump is down. Be prepared for.

これの原理を図2の手押しポンプ概念図により説明する。図2において、図1と同じ記号の機器または部品は同じものであるから説明を省く。40はシリンダー、45は連通穴45aを有するピストン、46はピストンを上下に動かすためのハンドル、47はピストンとハンドルを連結する連結棒、Aは下部弁、Bは上部弁である。
作動は図2の右側に示す4工程で実行される。先ず、水源1には大気圧10(水柱)がかかっているから、シリンダー内を負圧にすれば理論上水源の水を10m吸上げることが出来るが、途中の損失を考慮すると6m程度の吸上げとなる。第1の工程において、ピストンは最上位にて静止している。水位はピストン底面にあり、弁A、Bは共に閉じており、手押しポンプ吐出口から水は未だ吐出されない。ハンドルを途中まで引き上げ静止させたピストンがシリンダーの途中にある状態が第2の工程である。水位は水が吐出される直前の位置にあり弁Aは閉じ、弁Bは開いている。ハンドルを最上位まで引き上げ静止させたピストンがシリンダーの最下位にある状態が第3の工程である。水位は未だ水が吐出される直前の位置にあり、弁A、Bは閉じている。ハンドルを押し下げるとピストンの下部、シリンダー内が負圧となり水源の水を吸い上げ、ピストンの上部、シリンダー内の水が吐出口より吐き出される。こうしてハンドルを途中まで押し下げて静止させたピストンがシリンダーの途中にある状態が第4の工程である。弁Aは、開き弁Bは閉じている。勿論、ハンドルを最下位まで押し下げ静止するまで前記状態は継続する。即ち、水源の水はピストン底部、最上位まで吸い上げられている。(第1工程の状態)以下、第1〜第4工程を、繰り返し揚水をしていくこととなる。
The principle of this will be described with reference to the conceptual diagram of the hand pump shown in FIG. In FIG. 2, since the apparatus or component of the same symbol as FIG. 1 is the same, description is abbreviate | omitted. Reference numeral 40 denotes a cylinder, 45 denotes a piston having a communication hole 45a, 46 denotes a handle for moving the piston up and down, 47 denotes a connecting rod for connecting the piston and the handle, A denotes a lower valve, and B denotes an upper valve.
The operation is performed in four steps shown on the right side of FIG. First, since the atmospheric pressure 10 (water column) is applied to the water source 1, if the inside of the cylinder is set to a negative pressure, the water in the water source can theoretically be sucked up by 10m. It will be raised. In the first step, the piston is stationary at the top. The water level is at the bottom of the piston, valves A and B are both closed, and water is not yet discharged from the hand pump discharge port. The second step is a state in which the piston with the handle pulled up halfway and stationary is in the middle of the cylinder. The water level is at a position just before water is discharged, valve A is closed, and valve B is open. The state where the piston with the handle pulled up to the top and stationary is at the bottom of the cylinder is the third step. The water level is still at a position just before water is discharged, and the valves A and B are closed. When the handle is pushed down, the lower part of the piston and the inside of the cylinder become negative pressure, sucking up water from the water source, and the water in the upper part of the piston and cylinder is discharged from the discharge port. The state in which the piston, which has been stationary by pushing down the handle halfway in this way, is in the middle of the cylinder is the fourth step. The valve A is open and the valve B is closed. Of course, the state continues until the handle is pushed down to the lowest position and stopped. That is, the water from the water source is sucked up to the bottom of the piston, the top. (State of the first step) Hereinafter, the first to fourth steps are repeatedly pumped.

さて、次に吸込み管、吸込み分岐管、ポンプ内の呼び水、空気除去、満水機能の作用について詳細に説明する。使用初期は、前記吐出側合流管に取り付けた三方弁8を、a側を遮断、b−c側を開放する。即ち、手押しポンプ吐出し口から仮設トイレ側に送水する方向に切替えると共に、前記吸込み分岐管に取り付けた三方弁(仕切弁の場合は開放)を全方向に開放し、水源の水が前記手押しポンプへ吸込まれ、且つポンプ及びポンプ側分岐管の呼び水及び満水が出来るようにする。そして、最初に手押しポンプを運転して吸込み管、吸込み分岐管(手押しポンプの運転で通水される部位)及び手押しポンプへ水源の水を吸上げ、空気と吸上げた水と一緒に仮設トイレ側に排出して満水状態とする。この状態を維持しながら、前記ポンプの呼び水手段10の仕切弁11を開放し、呼び水じょうご又はタンク12に注水している水から呼び水を行い、ポンプ内及び該吸込み分岐管(ポンプ側の手押しポンプの運転で吸引されて通水される部位)の空気を揚水と一緒に仮設トイレ側へ送水し満水状態にする。これが完了したところで前記ポンプの呼び水手段の仕切弁11を閉じ、手押しポンプを停止する。この時に、呼び水じょうご又はタンク12の水がなくなり外気を吸い込まれないように前記仕切弁11を閉じる。続いて、前記吸込み分岐管の三方弁(仕切弁4の場合は閉じる)を、水源の水が前記ポンプへ吸込まれる側に切り替えて、吐出合流管の三方弁を、b側遮断し、a−c側を開放する。即ち、手押しポンプから仮設トイレ側への送水を遮断し、ポンプから仮設トイレ側へ送水されるよう前記三方弁を切替える。この後、前記非常電源装置10を作動させてポンプを優先して運転する。
そして、前記ポンプがダウンした場合は、仕切弁、三方弁の操作を最初の状態に切り替え、手押しポンプによるバックアップ運転を行うものである。
又、以上の一連の動作で吸込み管、吸込み分岐管及びポンプ内の空気を除去し満水状態にして前記ポンプが確実に揚水されるように手順化したものである。
Now, the operation of the suction pipe, the suction branch pipe, the priming water in the pump, the air removal, and the full water function will be described in detail. In the initial stage of use, the three-way valve 8 attached to the discharge side merging pipe is shut off on the a side and opened on the bc side. That is, the direction is switched to the direction in which water is supplied from the hand pump discharge port to the temporary toilet side, and the three-way valve (open in the case of the gate valve) attached to the suction branch pipe is opened in all directions. So that the pump and pump side branch pipes can be primed and filled. First, the hand pump is operated to suck up the water from the suction pipe, the suction branch pipe (portion through which the hand pump is operated) and the hand pump, and the temporary toilet together with the air and the sucked-up water. Drain to the side to make it full. While maintaining this state, the gate valve 11 of the priming means 10 of the pump is opened and priming water is poured from the priming funnel or water poured into the tank 12, and the inside of the pump and the suction branch pipe (hand pump on the pump side) The air of the part that is sucked and passed through in the operation of) is sent to the temporary toilet side along with the pumped water to make it full. When this is completed, the gate valve 11 of the pump priming means is closed and the hand pump is stopped. At this time, the gate valve 11 is closed so that the water in the priming funnel or the tank 12 runs out and the outside air is not sucked. Subsequently, the three-way valve of the suction branch pipe (closed in the case of the gate valve 4) is switched to the side where water from the water source is sucked into the pump, and the three-way valve of the discharge junction pipe is shut off on the b side, -Open the c side. That is, water supply from the hand pump to the temporary toilet is cut off, and the three-way valve is switched so that water is supplied from the pump to the temporary toilet. Thereafter, the emergency power supply device 10 is operated to operate the pump with priority.
And when the said pump goes down, operation of a gate valve and a three-way valve is switched to the first state, and the backup operation by a hand pump is performed.
Further, the procedure is made so that the air in the suction pipe, the suction branch pipe, and the pump is removed by the series of operations described above and the pump is fully pumped.

第1の実施形態の効果Effects of the first embodiment

このようにすると、災害時において非常電源駆動ポンプを優先して運転し、手押しポンプは前記非常電源駆動ポンプの呼び水、吸込み管の空気除去及び満水時の運転に制限して寿命の長時間化を図り、前記非常電源駆動ポンプダウン時のバックアップ運転を確実に行うことができ給水に対する信頼度を著しく向上させることができる。加えて、吸込み管、分岐管、ポンプ内の空気が確実に除去され満水状態となりポンプからの送水が確実に仮設トイレ側に送水され、[段落0007]で述べた従来の吸込み運転に関連する問題を解消することができる。  In this way, the emergency power supply pump is operated in priority in the event of a disaster, and the hand pump is limited to the priming water of the emergency power supply pump, the air removal of the suction pipe, and the operation when the water is full, thereby extending the life. Therefore, the backup operation when the emergency power supply pump is down can be reliably performed, and the reliability of water supply can be remarkably improved. In addition, the air in the suction pipe, branch pipe, and pump is reliably removed and the water is full, and the water from the pump is reliably sent to the temporary toilet side. Problems related to the conventional suction operation described in [paragraph 0007] Can be eliminated.

次に、第2の実施形態について説明する。これは、第1の実施形態において用いた非常電源である発電機を、燃料としてカセットボンベーを使用する発電機に代えて、且つ、システムの適切な部位に図示していないが温度計を備えたものでる。(図1参照)
即ち、発電機の燃料は、一般的には石油系が多く用いられているが、消防法により最大40Lまでしか備蓄が許されていない。燃料としてカセットボンベーを使用することを顧客から指定されることがある。カセットボンベーの使用条件は周囲温度5〜10℃以上であり、これ以下では使用できない問題がある。周囲温度が5〜10℃以下となる期間は手押しポンプでバックアップする必要がある。そこで、温度計の計測した外気温が前記周囲温度5〜10℃以下となった場合は、直ちにポンプを停止して手押しポンプを運転してバックアップを行う。そして、前記温度計の計測した外気温が前記周囲温度5〜10℃を越えて復帰した場合は、発電機駆動のポンプによる運転に切り替える。仕切弁、三方弁の切り替え、及びポンプと手押しポンプの切り替えは第1の実施態様と同じであるので説明は省く。
Next, a second embodiment will be described. This is because the generator as an emergency power source used in the first embodiment is replaced with a generator that uses a cassette bomb as a fuel, and a thermometer is provided in an appropriate part of the system, although not shown. It's a thing. (See Figure 1)
That is, as the fuel for the generator, petroleum-based fuel is generally used, but stocking up to 40 L at maximum is permitted by the Fire Service Act. Customers may specify the use of cassette cylinders as fuel. The usage condition of the cassette bomb is an ambient temperature of 5 to 10 ° C. or more, and there is a problem that it cannot be used below this temperature. It is necessary to back up with a hand pump during the period when the ambient temperature is 5 to 10 ° C. or lower. Therefore, when the ambient temperature measured by the thermometer becomes 5 to 10 ° C. or less, the pump is immediately stopped and the hand pump is operated to perform backup. When the outside air temperature measured by the thermometer returns after exceeding the ambient temperature of 5 to 10 ° C., the operation is switched to the operation by the generator-driven pump. Since the switching of the gate valve, the three-way valve, and the switching between the pump and the hand pump are the same as those in the first embodiment, description thereof will be omitted.

第2の実施形態の効果Effects of the second embodiment

このようにすれば、使用に制限(故障していなくても特定の期間は使用できない)のある非常電源である発電機の使用を指定されても、手押しポンプによるバックアップ運転で確実に給水することができる。  In this way, even if it is specified to use a generator that is an emergency power source that is restricted in use (it cannot be used for a specific period even if it is not broken down), water must be reliably supplied in a backup operation with a hand pump. Can do.

次に、第3の実施形態について説明する。これは、第1の実施形態において用いた非常電源駆動ポンプの駆動源をエンジンとしたものである。即ち、図1において、ポンプ5の駆動源である発電機を、図示していないがエンジンに代えたものである。手押しポンプへのバックアップの作動及び弁類の切り替え、及びポンプと手押しポンプの切り替えは第1の実施形態と同じであるので説明は省く。  Next, a third embodiment will be described. In this example, the drive source of the emergency power supply drive pump used in the first embodiment is an engine. That is, in FIG. 1, the generator that is the drive source of the pump 5 is replaced with an engine (not shown). Since the operation of backup to the hand pump and the switching of valves and the switching of the pump and the hand pump are the same as those in the first embodiment, the description thereof will be omitted.

第3の実施形態の効果Effects of the third embodiment

このようにすると、ポンプの駆動源がエンジンまで拡大し利便性が向上する他、エンジン駆動ポンプダウン時の手押しポンプへのバックアップは第1の実施態様と同じ効果が得られる。尚、エンジンの燃料も一般には石油系が用いられることが多い。この場合も、消防法による規制により、燃料としてカセットボンベーを使用することを顧客から指定されることが考えられるが、第2の実施形態と同様に対応することができる。  In this way, the pump drive source extends to the engine and the convenience is improved, and the backup to the hand pump when the engine drive pump is down provides the same effect as in the first embodiment. In general, petroleum fuel is often used for the engine. In this case as well, it is conceivable that the customer designates the use of a cassette bomb as fuel due to the regulations of the Fire Service Law, but this can be handled in the same manner as in the second embodiment.

次に、第4の実施形態について説明する。これは、第1〜第3の実施形態において、仕切弁と三方弁を自動弁に変更し、第1〜第3の実施形態で操作する手順を自動化し、誤操作による非常電源駆動ポンプダウン時の手押しポンプによるバックアップ運転不能、吸込み管及び吸込み分岐管の呼び水及び満水不能の問題を解消するようにしたものである。
これを図3により更に詳細に説明する。EGは非常電源装置である可搬式の発電機(例えば交流電力を発生する。)、BSSは起動押釦スイッチ、BSTは停止押釦スイッチ、43は43a(手押しポンプ運転モード/呼び水満水運転モード)と43b(非常電源駆動ポンプ運転モード)を切り替えるスイッチ、SVXはその接点SVXaで前記起動押釦スイッチBSSを自己保持するリレー、SVは前述した吸込み分岐管に取り付けられた三方弁4を説明の便宜上、仕切弁4−1に代え自動弁とした場合で示したものである。同じくDVは前述した吐出合流管に取り付けられた三方弁を自動弁としたものであり、DVbが励磁されるとc−b側が開放され、DVaが励磁されるとc−a側が開放されるものである。Tは計時終了(一定時間)後にその接点Taを閉じるタイマ、22は前述したポンプのモータである。本実施例の場合、モータ22は始動装置を内蔵しているものを用いているが、22を電磁開閉器とし、これの主回路接点を介して前記モータを駆動しても良い。30bはポンプ駆動モータ故障時に開放する接点、同じく30aはポンプ駆動モータ故障時に閉じる接点、31bは発電機故障時に開放する接点、同じく31aは発電機故障時に閉じる接点、BZは警報発報手段であり、例えばブザーである。
Next, a fourth embodiment will be described. This is because, in the first to third embodiments, the gate valve and the three-way valve are changed to automatic valves, the procedure for operating in the first to third embodiments is automated, and the emergency power supply pump is down due to an erroneous operation. It is intended to solve the problems of the impossibility of backup operation by a hand pump, the priming of the suction pipe and the suction branch pipe, and the inability to fill up.
This will be described in more detail with reference to FIG. EG is a portable power generator (for example, AC power is generated) as an emergency power supply, BSS is a start push button switch, BST is a stop push button switch, 43 is 43a (hand pump operation mode / priming full operation mode), and 43b. A switch for switching (emergency power supply pump operation mode), SVX is a relay that self-holds the activation pushbutton switch BSS at its contact SVXa, and SV is a three-way valve 4 attached to the aforementioned suction branch pipe for convenience of explanation. It is shown in the case of using an automatic valve instead of 4-1. Similarly, the DV is an automatic valve that is a three-way valve attached to the above-described discharge merging pipe. When DVb is excited, the cb side is opened, and when DVa is excited, the ca side is opened. It is. T is a timer that closes the contact Ta after the end of timekeeping (a fixed time), and 22 is the motor of the pump described above. In the case of the present embodiment, a motor 22 having a built-in starter is used, but 22 may be an electromagnetic switch, and the motor may be driven via a main circuit contact thereof. 30b is a contact that opens when the pump drive motor fails, 30a is a contact that closes when the pump drive motor fails, 31b is a contact that opens when the generator fails, 31a is a contact that closes when the generator fails, and BZ is an alarm reporting means For example, a buzzer.

このように構成した回路において、先ず、起動押釦スイッチBSSを押して、切替えスイッチ43を前記43a(手押しポンプ運転モード/呼び水満水運転モード)に切替える。これにより、自動弁SV(4−1)が開放し、自動弁DVのb−c側が開放する。そして、手押しポンプを運転し前述で明らかなので説明は省くが、呼び水及び満水を行う。呼び水満水が終了したら(人為的な判断)前記切替えスイッチ43を43a(手押しポンプ運転モード/呼び水満水運転モード)から43b(非常電源駆動ポンプ運転モード)に切替える。これに伴い、前記した自動弁SVが遮断され自動弁DVがc−a側(非常電源駆動ポンプから仮設トイレ側)に切り替わり、タイマTが計時を開始する。即ち、前記手押しポンプから仮設トイレ側への流れが遮断され、前記ポンプから仮設トイレ側への流れが確立する。前記タイマTが計時を終了すると、前記モータ22へ非常電源が印加されて該ポンプは運転を行う。前記タイマTの設定時間は、切替えスイッチ43を43a(呼び水満水運転モード)から43b(非常電源駆動ポンプ運転モード)に切り替えるのに十分な時間であればよい。さらにこの切り替えを人為的な判断に委ねることができれば前記タイマを省略しても良い。
このようにして運転している状態で、前記ポンプ駆動モータ又は発電機のいずれかが故障すると、前記30b又は31bのいずれかの接点が開放されポンプが停止し揚水不能となる。合わせて、前記30a又は31aのいずれかの接点が閉じて警報発報手段BZが作動し警報を発する。前記警報が発せられると、前記切替えスイッチ43を43b(非常電源駆動ポンプ運転モード)から43a(手押しポンプ運転モード/呼び水満水運転モード)に切替え、前記手押しポンプを運転しバックアップするのである。
尚、吸込み分岐管の弁を三方弁4とした場合については、前述で明らかなので説明を省略する。
In the circuit configured as described above, first, the start pushbutton switch BSS is pressed to switch the changeover switch 43 to the above-described 43a (hand pump operation mode / priming water full operation mode). Thereby, the automatic valve SV (4-1) is opened, and the bc side of the automatic valve DV is opened. Then, the hand pump is operated, and since it is obvious as described above, explanation is omitted, but priming and full water are performed. When the priming water is full (artificial judgment), the selector switch 43 is switched from 43a (hand pump operation mode / priming priming operation mode) to 43b (emergency power supply pump operation mode). Along with this, the automatic valve SV described above is shut off, the automatic valve DV is switched to the c-a side (from the emergency power supply pump to the temporary toilet side), and the timer T starts measuring time. That is, the flow from the hand pump to the temporary toilet is blocked, and the flow from the pump to the temporary toilet is established. When the timer T finishes timing, an emergency power supply is applied to the motor 22 and the pump operates. The set time of the timer T may be a time sufficient to switch the changeover switch 43 from 43a (priming water full operation mode) to 43b (emergency power supply pump operation mode). Furthermore, the timer may be omitted if this switching can be left to human judgment.
If either the pump drive motor or the generator fails while operating in this manner, either the contact 30b or 31b is opened, the pump is stopped, and pumping becomes impossible. At the same time, either the contact 30a or 31a is closed and the alarm issuing means BZ is activated to generate an alarm. When the alarm is issued, the changeover switch 43 is switched from 43b (emergency power supply pump operation mode) to 43a (hand pump operation mode / primed water full operation mode), and the hand pump is operated and backed up.
In addition, about the case where the valve | bulb of a suction branch pipe is made into the three-way valve 4, since it is clear above, description is abbreviate | omitted.

第4の実施形態の効果Effects of the fourth embodiment

このようにすると、誤操作による手押しポンプバックアップ不能及び前述した吸込み運転に伴う人為的な不具合を解消することができる。  In this way, it is possible to eliminate the inability to back up the hand pump due to an erroneous operation and the above-described artificial problems associated with the suction operation.

次に、第5の実施形態について説明する。これは、本仮設トイレ用給水システムが水源から離れて設置される場合について、更に改善したものである。吸込み管の横引き長さが長くなり、吸込み管の曲りが増加すると前述した手押しポンプ運転によるポンプ、吸込み管、吸込み分岐管の呼び水、空気除去、満水がより一層困難となる。そこで、前述した切替えスイッチ43を43a(手押しポンプ運転モード/呼び水満水運転モード)に切り替えて運転し、続いて43b(非常電源駆動ポンプ運転モード)に切り替えて運転するサイクルを1サイクルとし、これを数回繰り返し、ポンプのリトライ運転による揚水の可否を判定する。揚水が可能であれば正常状態であるからこのモードでの運転を続け、揚水不能であれば前記切替えスイッチ43を43aに切り替えて手押しポンプによる運転でバックアップする。
図1において、ポンプの吸込み側に真空計、ポンプ吐出し側に圧力計を取り付ければポンプの異常を容易に検出することができる。図3において自動弁SVとタイマTとに併設してカウンタを取り付け、これらの出力を直列にして警報発報手段BZに接続すれば、前記リトライ(繰り返し)回数を設定することができる。そして、警報発報手段BZが警報発信したらポンプの運転から手押しポンプによるバックアップ運転へ切り替えるようにすれば、第4の実施態様と同様に誤操作によるバックアップ不能を回避することができる。
Next, a fifth embodiment will be described. This is a further improvement in the case where the water supply system for the temporary toilet is installed away from the water source. If the length of the suction pipe becomes longer and the bending of the suction pipe increases, it becomes more difficult to perform priming, air removal, and water filling of the pump, suction pipe, and suction branch pipe by the above-described manual pump operation. Therefore, the above-described changeover switch 43 is switched to 43a (hand pump operation mode / primed water full operation mode) and then operated to 43b (emergency power supply pump operation mode) as one cycle. Repeat several times to determine whether pumping is possible by retrying the pump. If pumping is possible, it is in a normal state, so operation in this mode is continued. If pumping is not possible, the changeover switch 43 is switched to 43a and backed up by operation with a hand pump.
In FIG. 1, if a vacuum gauge is attached to the suction side of the pump and a pressure gauge is attached to the discharge side of the pump, abnormality of the pump can be easily detected. In FIG. 3, if a counter is attached to the automatic valve SV and the timer T and these outputs are connected in series to the alarm issuing means BZ, the number of retries (repetition) can be set. Then, if the alarm issuance means BZ issues an alarm, switching from the pump operation to the backup operation by the hand-pump pump can avoid backup failure due to an erroneous operation as in the fourth embodiment.

第5の実施形態の効果Effects of the fifth embodiment

このようにすれば、ポンプの異常時にも手押しポンプでバックアップして仮設トイレへ確実に給水することができる。  In this way, even when the pump is abnormal, it can be backed up by the hand pump and reliably supplied to the temporary toilet.

図4により、第6の実施形態について説明する。第1〜4の実施形態に基づく各弁類の開閉操作、手押しポンプ及び非常電源ポンプの運転操作を手順化し、注意銘板又は看板に記載し掲示してガイダンス機能を付加したものである。図4において、例えば40は看板、40aは注意銘板や注意書きである。  The sixth embodiment will be described with reference to FIG. The opening / closing operation of each valve based on the first to fourth embodiments, the operation operation of the hand pump and the emergency power supply pump are made into procedures, are displayed on a caution nameplate or a signboard, and are added with a guidance function. In FIG. 4, for example, 40 is a signboard, and 40a is a caution name plate or a caution note.

第6の実施形態の効果Effects of the sixth embodiment

このようにすると、操作のしかたが一般に周知徹底され、誤操作による前述した吸込み運転に伴う人為的な不具合を解消することができる。第3の実施形態においては、呼び水満水機能を更に向上させることができる。  In this way, the method of operation is generally well known, and the above-mentioned artificial problems associated with the suction operation due to erroneous operation can be solved. In the third embodiment, the priming water full function can be further improved.
