【発明の属する技術分野】
本発明は、ポンプなどの各種駆動装置を備えた車両に搭載され、駆動装置を駆動させるために発電機からの電力を調整して供給する電気機器が収納された電気盤を備えたポンプ車に関するものである。
【0002】
【従来の技術】
従来より、例えば、排水ポンプ、消火ポンプ、送水ポンプ等の各種ポンプなどの駆動装置を備えた車両には、その駆動装置を駆動させるために発電機からの電力を調整して供給する電気機器が収納された電気盤が搭載されている。
この種の電気盤を搭載した車両として、洪水時等において、その浸水現場の水を排水させる排水ポンプ車を例にとって説明する。
【0003】
図10において、符号1は、電気盤であり、この電気盤1は、後述する排水ポンプPが収納された収納箱2とともに車両3の荷台4上に搭載されている。また、この車両3の荷台4には、電源として発電機5も搭載されており、この発電機5からの電力が電気盤1内のトランスやインバータ等の電気機器によってコントロールされて排水ポンプPへ供給され、駆動させるようになっている。
なお、発電機5の代わりにバッテリー等の他の電源を用いる場合もある。
そして、上記の電気盤1を有する排水ポンプ車では、図11に示すように、浸水現場にて、まず、収納箱2内の排水ポンプPを引き出し、この排水ポンプPを浸水場所へ設置する。また、必要に応じて、作業現場を照明すべく、収納箱2内に収納された図示しないライトを取り出して設置する。
この状態にて、電気盤1によって排水ポンプPを駆動させる。また、ライトの点灯を行う。
【0004】
このようにすると、発電機5等の電源からの電力が電気盤1内のトランスやインバータを介して排水ポンプPやライトへ供給され、ホース6を介して排水ポンプPによって浸水場所から水が汲み上げられる。
【0005】
ところで、トランスやインバータ等の各種電気機器が内蔵された電気盤1では、その内部の電気機器を冷却させるために、筐体1aの下方側に吸気口7、上方側に排気口8をそれぞれ設け、電動ファンによって吸気口7から空気を取り入れ、排気口8から排気させることにより、内部に設置された発熱体である各種電気機器を冷却させていた。
【0006】
【発明が解決しようとする課題】
ところで、排水ポンプ車は勿論のこと、屋外で使用され、しかも、雨天での使用が多いポンプ車の電気盤1にあっては、水分に弱い電気機器が設置されているので、雨水の浸入に対して十分に防水対策を施す必要がある。
このため、冷却のために空気を取り入れる吸気口7は勿論のこと、排気口8からの雨水の降り込みも確実に防ぐため、これら吸気口7、排気口8にフィルタを設置したり、雨水が降りこまないような形状に形成したり、各種の専用の防水対策を施さなければならず、電気盤1の大型化や重量増加を招き、結果的にコストアップを招いてしまっていた。
【0007】
この発明は、上記事情に鑑みてなされたもので、大型化、大重量化を招くことなく低コストにて、内部の電気機器を良好に冷却することが可能な電気盤を備えたポンプ車を提供することを目的としている。
【0008】
【課題を解決するための手段】
上記目的を達成するために、請求項1記載のポンプ車は、車両の荷台に設置された電源と、前記車両の荷台に設けられ前記電源からの電力を調整してポンプへ供給して駆動させる電気機器が収納された電気盤とを有するポンプ車において、前記電気盤は、筐体内に各種の電気機器が収納される電気機器収納部が設けられた電気盤であって、前記筐体内には、前記電気機器収納部に隣接するように、各種の機材を収納可能な機材収納空間部が形成され、該機材収納空間部と前記電気機器収納部とを区画する区画壁には、前記機材収納空間部と前記電気機器収納部とを連通させる吸気口及び排気口が形成され、前記機材収納空間部側の前記吸気口及び排気口の両方もしくはいずれか一方には、前記機材収納空間部内の空気を前記電気機器収納部内へ引き込むとともに前記電気機器収納部内の空気を前記機材収納空間部へ排気させる送風手段が設けられていることを特徴としている。
【0009】
つまり、電気機器収納部内の電気機器を冷却する空気を、電気機器収納部に隣接する機材収納空間部から引き込み、その後、機材収納空間部へ送り出す構造であるので、冷却用の空気を外部から電気機器収納部へ直接取り入れて外部へ排気させる場合と比較して、特別な防水構造を施すことなく、雨水などの水滴の電気機器収納部への侵入なく、電気機器収納部内の電気機器の冷却を行うことができる。
これにより、特別な防水構造を施すことによる大型化や重量増加を抑え、コストの低減を図ることができる。
また、外部の空気を電気機器収納部へ直接取り入れる構造と比較して、粉塵等の浸入も確実に防ぐことができ、粉塵による電気機器への悪影響をなくすことができる。
更に、機材収納空間部は、単に、各種の機材を収納させておくだけの空間部分であるので、特に、電気盤の不使用時において、その空間部内に各種の機材を収納させて、そのスペースの有効利用を図ることができる。
また、このように、水の汲み上げや放水を行うポンプへの電力の調整を行う電気盤が、特別な防水構造を施すことなく、電気機器収納部内の各種の電気機器の冷却を良好に行うことができ、しかも小型、軽量かつ低コスト化されているので、発電機等の電源とともに電気盤が荷台に搭載される車両の小型化も図ることができ、設備費の低減を図ることができる。
【0010】
請求項2記載のポンプ車は、請求項1記載のポンプ車において、前記機材収納空間部が、前記電気機器収納部の側方に設けられ、前記吸気口は前記区画壁の下方側に形成され、前記排気口は前記区画壁の上方側に形成されていることを特徴としている。
【0011】
このように、下方から取り入れた空気を上方から排気させることができるので、電気機器収納部内の電気機器の冷却を、熱の流れに沿って良好に行うことができる。
【0012】
請求項3記載のポンプ車は、請求項1または請求項2記載のポンプ車において、前記送風手段が、前記排気口に設けられていることを特徴としている。
【0013】
すなわち、上方の排気口に設けた送風手段によって電気機器収納部内の空気を機材収納空間部へ吸い出すことにより、電気機器収納部内の空気を確実に吸い出して排気させ、吸気口から電気機器収納部内へ吸い込ませて電気機器を冷却させることができる。
【0014】
請求項4記載のポンプ車は、請求項1〜3のいずれか1項記載のポンプ車において、前記機材収納空間部が、仕切板によって、少なくとも前記吸気口と連通する吸気側空間部と、前記排気口と連通する排気側空間部とに分割され、前記筐体には、前記吸気側空間部と外部とを連通させる吸気窓と、前記排気側空間部と外部とを連通させる排気窓とが形成されていることを特徴としている。
【0015】
つまり、外部の空気を吸気窓から吸気側空間部を介して電気機器収納部内へ取り入れ、その後、電気機器収納部内の空気を排気側空間部を介して排気窓から外部へ排気させるので、吸気窓に特別な防水構造を施さなくても、吸気窓から入り込む雨水等の水滴を吸気側空間部にて確実に除去して電気機器収納部内へ外気を導くことができる。
【0018】
請求項5記載のポンプ車は、請求項1〜4のいずれか1項記載のポンプ車において、前記電気機器が前記区画壁に固定されていることを特徴としている。
【0019】
つまり、区画壁に固定された電気機器の熱を区画壁を介して筐体全体へ逃がすことができ、これにより、特に、熱の影響を受けやすいインバータ等の電気機器に好適である。
【0022】
【発明の実施の形態】
以下、本発明の実施形態例の電気盤を備えたポンプ車を図面を参照して説明する。
図1において、符号11は、本実施形態例の電気盤であり、この電気盤11は、車両12の荷台13上に設置されている。
また、この車両12には、その荷台13の後方側に、電源として発電機14が設置されている。
電気盤11には、その正面側における下端部分に、複数のコネクタ15が設けられており、これらコネクタ15には、発電機14、アース棒17、排水ポンプP及びライト18が、ケーブル19を介して接続されるようになっている。
【0023】
次に、車両12の荷台13上に設置された電気盤11の具体的な構成及び構造について図2から図7によって説明する。
図に示すように、この電気盤11は、この電気盤11を構成する筐体11aの正面に、開閉可能な扉21が設けられており、これら扉21の一方には、コネクタ15に接続した排水ポンプP、ライト18の駆動のON・OFFや制御を行うべく操作される操作パネル22と、これら排水ポンプPやライト18などの駆動状態等を表示させる表示パネル23が設けられている。
【0024】
そして、この電気盤11は、扉21によって開閉される側が電気機器収納部24とされており、この電気機器収納部24内に、各種の電気機器が収納されている。
また、この電気盤11には、その裏面、開閉可能な扉31が設けられており、これら扉31によって開閉される側が機材収納空間部32とされている。
そして、この電気盤11の電気機器収納部24と機材収納空間部32とが、区画壁33によって区画されている。
【0025】
電気機器収納部24内には、その下方にトランス41が設けられ、また、中央部分には、区画壁33に治具等により密着固定されたインバータ42が設けられている。
また、区画壁33には、その下方側及び上方側に、それぞれ吸気口43、排気口44が設けられており、排気口44には、電気機器収納部24側に、電動ファン(送風手段)45が設けられている。
【0026】
機材収納空間部32は、水平方向に配設された複数の棚部(仕切板)51によって上下に複数の収納空間部52に分割されており、下段の収納空間部52に、吸気口43が連通され、上段の収納空間部52に、排気口44が連通されている。
ここで、この機材収納空間部32には、下段の収納空間部52に、排水ポンプP及びケーブル19が収納され、中段の収納空間部52に、排水ポンプPに接続するホース6が収納され、上段の収納空間部52に、ライト18及びケーブル19が収納されている。
そして、下段の収納空間部52が吸気側空間部52aとされ、上段の収納空間部52が排気側空間部52bとされている。
【0027】
また、この機材収納空間部32を開閉させる扉31の一方には、その下方に吸気窓53が、上方に排気窓54がそれぞれ形成されている。そして、吸気窓53は、吸気側空間部52aと連通され、排気窓54は、排気側空間部52bと連通されている。
【0028】
次に、上記構造の電気盤1を備えた排水ポンプ車によって浸水場所における排水作業を行う場合について説明する。
まず、車両12の荷台13に設置された電気盤11の裏面側の扉31を開き、機材収納空間部32を開口させる。
次いで、この機材収納空間部32のそれぞれの収納空間部52内に収納された排水ポンプP、ライト18、ケーブル19及びホース6等の機材を取り出し、排水ポンプP、ライト18のケーブル19を電気盤11のコネクタ15に接続する。そして、これら排水ポンプP、ライト18ケーブル19及びホース6等の機材を取り出したら、扉31を閉じて機材収納空間部32を閉めておく。
【0029】
また、ホース6を排水ポンプPに接続し、その端部を排水側の河川等に配設するとともに、排水ポンプPを浸水場所へ設置する。
また、発電機14等の電源からの電力供給用のケーブル19も、電気盤11の電力入力用のコネクタ15に接続しておく。
【0030】
この状態にて、電気盤11の正面に設けられた操作パネル22にて、排水ポンプPを駆動させるとともに、必要に応じてライト18を点灯させる。
このようにすると、排水ポンプPから吸い上げられた浸水場所の水が、ホース6を通して、河川等の排水場所へ送り出され、浸水場所の排水が行われる。
【0031】
ここで、このように、電気盤11によって各種の機材を駆動させると、この電気盤11の機材収納空間部32とを区画している区画壁33の上部の排気口44に設けられた電動ファン45が駆動される。
【0032】
これにより、図8に示すように、機材収納空間部32側の扉31の下方側に設けられた吸気窓53から吸気側空間部52aへ外気が吸気され、その後、この吸気された外気は、区画壁33の下方側に設けられた吸気口43から電気機器収納部24内に導かれ、さらに、この電気機器収納部24を、その下方から上方へ向かって流された後、電動ファン45によって排気口44から機材収納空間部32の排気側空間部52bへ送り出され、この排気側空間部52bと連通している扉31に形成された排気窓54から外部へ排気される。
【0033】
これにより、電気機器収納部24では、下方の吸気口43から吸い込まれて上方の排気口44から送り出される空気によって、その内部における底部に配設されたトランス41や区画壁33に固定されたインバータ42等の発熱を生じる電気機器が冷却される。
また、このとき、吸気口43から吸い込まれる冷却空気は、機材収納空間部32の吸気側空間部52aを介して十分に流速が低減されて、含まれる水滴が十分に除去された状態にて、電気機器収納部24へ送り込まれる。
【0034】
このように、上記実施形態例の電気盤11によれば、吸気口43から吸い込まれる冷却空気は、機材収納空間部32の吸気側空間部52aを介して十分に流速が低減されて、含まれる水滴が十分に除去された状態にて、電気機器収納部24へ送り込まれるので、冷却空気中に含まれる水滴による電気機器への影響をなくすことができ、さらには、電気機器収納部24内への粉塵の侵入も抑えられ、電気機器への悪影響をなくすことができる。
【0035】
また、機材収納空間部32の各収納空間部52は、単に、各種の機材を収納させておくだけの空間部分であるので、吸気窓53や排気窓54から、多少雨水が降り込んでも問題がなく、したがって、電気機器収納部24へ冷却空気を取り入れる吸気口43、吸気窓54及び電気機器収納部24から排気させる排気口44、排気窓54に特別な防水構造を施す必要をなくすことができる。
【0036】
つまり、冷却用の空気を外部から電気機器収納部24へ直接取り入れて外部へ排気させる場合と比較して、雨水などの水滴の電気機器収納部24内への侵入なく、電気機器収納部24内のトランス41やインバータ42などの電気機器の冷却を行うことができ、特別な防水構造を施すことによる大型化や重量増加を抑え、コストの低減を図ることができる。
【0037】
また、下方から取り入れた空気を上方から排気させるので、電気機器収納部24内の電気機器の冷却を、熱の流れに沿って良好に行うことができる。
しかも、上方の排気口44に設けた電動ファン45によって電気機器収納部24内の空気を機材収納空間部32へ吸い出すことにより、電気機器収納部24内の空気を確実に吸い出して排気させ、吸気口43から電気機器収納部24内へ吸い込ませて電気機器を冷却させることができる。
【0038】
また、電気機器収納部24との間にて吸気、排気が行われる空間部が、排水ポンプP、ライト18、ケーブル19やホース6等の各種の機材を収納させる機材収納空間部であるので、特に、電気盤11の不使用時において、内部に各種の機材を収納させて、そのスペースの有効利用を図ることができる。
さらには、区画壁33に固定された電気機器の熱を区画壁33を介して筐体11a全体へ逃がすことができ、これにより、特に、熱の影響を受けやすいインバータ42等の電気機器に好適である。
【0039】
そして、上記の電気盤11を備えた排水ポンプ車によれば、水の汲み上げを行う排水ポンプPへの電力の調整を行う電気盤11が、特別な防水構造を施すことなく、電気機器収納部24内の各種の電気機器の冷却を良好に行うことができ、しかも、小型、軽量かつ低コスト化されているので、発電機14とともに電気盤11が荷台13に搭載される車両12の小型化も図ることができ、設備費の低減を図ることができる。
【0040】
なお、上記の例では、電気機器収納部24と機材収納空間部32とを横方向に併設して一体化した構造としたが、これら電気機器収納部24と機材収納空間部32とを上下方向に併設して一体化しても良い。この場合は、下方側を機材収納空間部32とし、この下方側の機材収納空間部32から収納空間部32内に空気を取り入れて上方側の電気機器収納部24へ導くようにし、その後、この電気機器収納部24から下方側の機材収納空間部32の他の収納空間部を介して外部へ排気させるようにすれば良い。
【0041】
また、上記実施形態例では、機材収納空間部32を開閉させる扉31に、吸気窓53及び排気窓54を設け、外部から空気を導入し、電気機器収納部24内の電気機器の冷却後に外部へ排気させる構造としたが、図9に示すように、これら吸気窓53及び排気窓54をなくすとともに、機材収納空間部32の棚部51に切欠や孔を形成して、各段の収納空間部52同士を連通させた構造とし、電気機器収納部24の排気口44から排気された空気を、機材収納空間部32の下方へ導き、吸気口43から電気機器収納部24内へ再び送り込むように、空気を循環させて電気機器収納部24内の電気機器を冷却させるようにしても良い。
【0042】
このようにすると、外気中に含まれている粉塵の電気機器収納部24内への侵入を、さらに確実に防止することができ、粉塵による電気機器への悪影響をなくすことができる。
【0043】
なお、上記の例では、電気盤11を車両12の荷台13に搭載させた排水ポンプ車について説明したが、この電気盤11は、排水ポンプ車に限らず、各種の機材を駆動させる電気盤11を要する、例えば、消火ポンプ車、送水ポンプ車等にも適応することができるのは勿論である。
また、上記の例では、車両12上に、電源として発電機14を搭載させて、この発電機14からの電力を電気盤11へ供給したが、電気盤11へ電力を送る電源としては、発電機に限定されることはない。
【0044】

請求項1記載のポンプ車によれば、電気機器収納部内の電気機器を冷却する空気を、電気機器収納部に隣接する機材収納空間部から引き込み、その後、機材収納空間部へ送り出す構造であるので、冷却用の空気を外部から電気機器収納部へ直接取り入れて外部へ排気させる場合と比較して、特別な防水構造を施すことなく、雨水などの水滴の電気機器収納部への侵入なく、電気機器収納部内の電気機器の冷却を行うことができる。
これにより、特別な防水構造を施すことによる大型化や重量増加を抑え、コストの低減を図ることができる。
また、外部の空気を電気機器収納部へ直接取り入れる構造と比較して、粉塵等の浸入も確実に防ぐことができ、粉塵による電気機器への悪影響をなくすことができる。
