On the other hand, when a disaster occurs, the water in the water storage tank is used. There is an advantage that drinking water can be obtained by washing with a water purifier.

しかしながら、特許文献１に記載の車両は、貯水タンク付作業自動車なので、緊急時の機能は限定的であるという問題点がある。すなわち、普通一般の消防自動車の如く消火活動を十分に発揮することができる訳ではなく、また、浄水器６５で浄水する水も貯水タンク７に貯蔵される量に限定されるという問題点があった。そこで、現在、このような問題点を解決する緊急車両の出現が要望されている。 However, since the vehicle described in Patent Document 1 is a work vehicle with a water storage tank, there is a problem that the function in an emergency is limited. That is, the fire extinguishing activities cannot be sufficiently performed like ordinary fire engines, and the water purified by the water purifier 65 is limited to the amount stored in the water storage tank 7. It was. Therefore, the emergence of an emergency vehicle that solves such problems is currently desired.

The primary treatment filtering means 13A1 for filtering the raw water a from the outside through the gap 63 of the elastic ring-shaped portion 62, and attached to the gap 63 of the elastic ring-shaped portion 62, or When removing the impurities f captured by the elastic ring-shaped portion, cleaning water is introduced into the elastic filter member 61 via a cleaning flow path (cleaning line) L4 provided in the container 51, and the pressure of the cleaning water Stretched by It is to remove by utilizing gaps 63 of the elastic ring-shaped portion 62 that elastically displaced in a direction of the washing water a out of the elastic filter member 61 ".

上記洗浄流路Ｌ４は、綺麗な水を供給する消火栓２３に消防ホース（吸引ホース）２２を介して接続可能である。また洗浄流路Ｌ４は、消防自動車が搭載する洗浄ポンプ６４を有していると共に、洗浄開閉弁（ここでは第３開閉弁）６５を介して接続配管６６の二股状の外端部の一方の接続口に接続している。前記接続配管６６の内端部は固定支持板５２を介して弾性フィルタ部材６１の上端部に連結されている。 The washing channel L4 can be connected to a fire hydrant 23 that supplies clean water via a fire hose (suction hose) 22. The cleaning flow path L4 has a cleaning pump 64 mounted on a fire engine, and one of the outer ends of the bifurcated outer shape of the connection pipe 66 via a cleaning on-off valve (here, a third on-off valve) 65. Connected to the connection port. An inner end portion of the connection pipe 66 is connected to an upper end portion of the elastic filter member 61 through a fixed support plate 52.

縦長状の容器５１の具体的構成の説明は割愛するが、該容器５１は、側周面に原水流入口５１ａ、底部の略中央部に不純物ｆ用の排出口５１ｂ、上端部寄りの部位に接続配管６６用の嵌合孔５１ｃ、上端部の略中央部に圧力センサ６７等を有する。
そして、前記原水流入口５１ａには第１開閉弁６８、前記接続配管６６の二股状の外端部の他の接続口には第２開閉弁６９、前記排出口５１ｂには第４開閉弁７０がそれぞれ設けられている。 Although the description of the specific configuration of the vertically long container 51 is omitted, the container 51 has a raw water inlet 51a on the side peripheral surface, a discharge port 51b for impurities f at a substantially central portion of the bottom, and a portion near the upper end. A fitting hole 51c for the connecting pipe 66 is provided, and a pressure sensor 67 and the like are provided at a substantially central portion of the upper end portion.
The raw water inlet 51a has a first on-off valve 68, the other connecting port of the connecting pipe 66 has a second on-off valve 69 at the other connection port, and the discharge port 51b has a fourth on-off valve 70. Are provided.

第１乃至第４開閉弁６８、６９、６５、７０の開閉は運転制御部７によって制御される。また圧力センサ６７の信号は運転制御部７によって制御される。さらに、洗浄ポンプ６４の作動も運転制御部７によって制御される。 The opening and closing of the first to fourth on-off valves 68, 69, 65, 70 is controlled by the operation control unit 7. The signal from the pressure sensor 67 is controlled by the operation control unit 7. Further, the operation of the cleaning pump 64 is also controlled by the operation control unit 7.

なお、符号７１は容器５１の内部の底部側に設けられた複数の透孔を有する支持板（仕切板）、７２は支持板７１と可動支持板５３との間に介在する間隔微調整手段である。
図１１は弾性フィルタ部材６１に不純物ｆが付着した状態の説明図である。この図１１から明らかなように、第１開閉弁６８と第２開閉弁６９が同時に開き（この時、第３開閉弁６５と第４開閉弁７０は閉じている）、原水ａは弾性フィルタ部材６１の間隙６３を通過する際に、不純物ｆが前記間隙６３に付着する。一方、図１２は弾性フィルタ部材６１の不純物ｆを除去した状態の説明図である。 Reference numeral 71 is a support plate (partition plate) having a plurality of through holes provided on the bottom side inside the container 51, and 72 is a fine spacing adjustment means interposed between the support plate 71 and the movable support plate 53. is there.
FIG. 11 is an explanatory view showing a state in which the impurity f is attached to the elastic filter member 61. As is apparent from FIG. 11, the first on-off valve 68 and the second on-off valve 69 are opened simultaneously (the third on-off valve 65 and the fourth on-off valve 70 are closed at this time), and the raw water a is an elastic filter member. Impurities f adhere to the gap 63 when passing through the gap 63 of 61. On the other hand, FIG. 12 is an explanatory view showing a state in which the impurity f of the elastic filter member 61 is removed.

ここで、第２実施形態の不純物ｆの除去に関する作用を簡単に説明すると、第１開閉弁乃至第４開閉弁６８、６９、６５、７０の開閉は運転制御部７によって、例えば一定の時間毎に制御され、第１開閉弁６８と第２開閉弁６９が同時に「閉」の状態の時には、第３開閉弁６５と第４開閉弁７０は同時に「開」の状態となり、弾性フィルタ部材６１の自動洗浄が実行される（図１２参照）。その結果、不純物ｆは容器５１の排出口５１ｂから排出される。 Here, the operation relating to the removal of the impurity f of the second embodiment will be briefly described. The opening / closing of the first to fourth on-off valves 68, 69, 65, 70 is performed by the operation control unit 7 at regular intervals, for example. When the first on-off valve 68 and the second on-off valve 69 are simultaneously in the “closed” state, the third on-off valve 65 and the fourth on-off valve 70 are simultaneously in the “open” state, and the elastic filter member 61 Automatic cleaning is performed (see FIG. 12). As a result, the impurity f is discharged from the discharge port 51b of the container 51.

上記構成の濾過手段１３Ａ１を用いると、弾性フィルタ部材６１の弾性リング状部分６２の隙間６３或いは多数の溝が泥等の不純物ｆで詰まった状態となり、その結果、フィルタ機能が減退するのを防止することができる。 When the filtering means 13A1 having the above configuration is used, the gap 63 or a large number of grooves of the elastic ring-shaped portion 62 of the elastic filter member 61 is clogged with impurities f such as mud, thereby preventing the filter function from being deteriorated. can do.

すなわち、好ましくは消火栓２３からの原水ａを洗浄水とし、該洗浄水ａを弾性フィルタ部材６１の内部に導き、該洗浄水ａの圧力によって伸びる方向へ弾性変位する弾性リング状部分６２の隙間６３を利用して該洗浄水ａを該弾性フィルタ部材６１の外へ除去する物理的原理を採用したので、弾性フィルタ部材６１の同心円上に多数のノズルを有する洗浄パイプを配設する必要がない。また弾性フィルタ部材６１に付着した或いは弾性フィルタ部材６１が捕獲した不純物ｆを略綺麗に除去することができる。 That is, preferably, the raw water a from the fire hydrant 23 is used as cleaning water, the cleaning water a is guided into the elastic filter member 61, and the gap 63 of the elastic ring-shaped portion 62 is elastically displaced in the direction of extension due to the pressure of the cleaning water a. Since the physical principle of removing the washing water a to the outside of the elastic filter member 61 by using the above is adopted, it is not necessary to dispose a washing pipe having a large number of nozzles on the concentric circle of the elastic filter member 61. Further, the impurities f attached to the elastic filter member 61 or captured by the elastic filter member 61 can be removed substantially neatly.
