Description

【０００１】
【発明の属する技術分野】
この発明は、移動電源車などの発電装置に関し、特にその排気口の蓋構造に関するものである。
【０００２】
【従来の技術】
一般に、自然災害などによる広域停電発生時には、高圧配電線や引込線に移動電源車の電源を接続し、ライフラインを確保することが行われている。
【０００３】
図６は特開平１０−１５７５１０号に示された従来の移動電源車の側面図を示し、１はワンボックスカーからなる車両であり、内部は仕切られてないが、一応運転室部分１ａと荷室部分１ｂとに分けられる。荷室部分１ｂの後部の上部には吸気口２が設けられるとともに、前部の上部には排気口３が設けられている。４は荷室部分１ｂ内の後部に設けられた発電機制御盤、５は発電機制御盤４の下方に設けられた発電機、６は発電機５の前方に設けられ、発電機５を駆動するディーゼルエンジン、７はエンジン６の前方に設けられ、エンジン６により駆動されるラジエータファン、８はラジエータファン７の前方に設けられ、エンジン６を冷却するラジエータ、９はラジエータ８の前方に設けられたマフラーであり、エンジン６の排気管１０の途中に設けられている。又、荷室部分１ｂの左側面前部にはスライド式扉１２が設けられ、荷室部分１ｂの周壁の内側及び運転室部分１ａと荷室部分１ｂの間には防音壁１１が全面的に設けられている。なお、防音壁１１は実際には外部から見えないが、分かり易いように実線で示している。１３は排気口３に開閉自在に設けられた蓋である。
【０００４】
上記構成において、エンジン６を駆動すると、発電機５が発電を行う。又、ラジエータファン７も回転し、ラジエータ８を冷却する。外気は吸気口２から吸い込まれ、ラジエータ８等の周囲を通って排気口３から排出される。このとき、ラジエータ８の周囲の加熱空気も排出される。又、エンジン６からの排気はマフラー９により消音され、排気管１０を介して排気口３から排出される。荷室部分１ｂにおいては、エンジン６等は騒音を発生するが、防音壁１１により囲まれているので、外部にはほとんど漏れない。
【０００５】
【発明が解決しようとする課題】
上記した従来の移動電源車においては騒音があまり外部に漏れないように防音壁１１を設け、また排気口３には開閉自在な蓋１３が設けられている。
【０００６】
しかしながら、発電機５の運転中は蓋１３が開かれているので、内部で発生した騒音、エンジン６からの排気ガス、熱風等が排気口３から排出される。このため、特に騒音に対しては周辺の居住者からの苦情が高まるおそれがあった。
【０００７】
そこで、従来では騒音等の排出方向を選択できるようにしたものがあり、これについて図７により説明する。図７において、蓋１３は抜き差しヒンジ１４を介して排気口３の一方の側に開閉自在に取り付けられているが、蓋１３は排気口３の他方の側にも取り付け可能となっている。１５は車両１内の固定部に一端が連結された伸縮シリンダであり、その他端は蓋１３の裏側に連結されており、蓋１３を伸縮シリンダ１５により開閉するようになっている。従って、この移動電源車では、蓋１３の取付位置を変更することにより、配置された環境に対応して排風方向を変え、騒音や排気ガス等の流出方向を変えることができる。
【０００８】
しかしながら、図７に示した移動電源車では、排気口３の蓋１３を抜き差しヒンジ１４により設置した側への騒音等の流出は防止できるが、矢印で示したその他の三方向には騒音等が流出した。このことは、蓋１３の設置位置を変えても同様であった。
【０００９】
【課題を解決するための手段】
請求項１に係る発明は、発電機と該発電機を駆動する機関とを箱体内に収納するとともに、前記箱体に設けた通風口から排出される排気や騒音を上方にのみ排出する筒状の排気ダクトを設けた発電装置において、
前記排気ダクトを、前記通風口の第１の辺に沿ってヒンジによって回動自在に取り付けられていて前記通風口の上方に向かって垂直方向に伸びた状態から前記通風口を塞ぐ方向に傾斜可能な蓋と、該蓋を取り付けた前記通風口の第１の辺と対向する第２の辺に沿ってヒンジによって回動自在に取り付けられていて前記通風口の上方に向かって垂直方向に伸びた状態から前記通風口を塞ぐ方向に傾斜可能な遮蔽板と、前記蓋の一側部から前記遮蔽板の一側部に向けて前記通風口の第１の辺と第２の辺以外の第３の辺に沿って伸びる円弧状の第１の遮蔽部材と、前記遮蔽板の一側部から前記蓋の一側部に向けて前記第３の辺に沿って伸びて前記第１の遮蔽部材に重合する円弧状の第２の遮蔽部材と、前記蓋の他側部から前記遮蔽板の他側部に向けて前記通風口の前記第３の辺と対向する第４の辺に沿って伸びる円弧状の第３の遮蔽部材と、前記遮蔽板の他側部から前記蓋の他側部に向けて前記第４の辺に沿って伸びて前記第１の遮蔽部材に重合する円弧状の第４の遮蔽部材と、で構成した。
【００１０】
【課題を解決するための手段】
この発明の請求項１に係る発電装置は、発電機と該発電機を駆動する機関とを箱体内に収納するとともに、この箱体に開閉自在な蓋を付設した通風口を設け、かつ、蓋の回動軸となる通風口の辺以外の少なくとも一辺に排気及び騒音を遮蔽する遮蔽部材を設けたものである。
【００１３】
【発明の実施の形態】
実施形態１（参考例１）
以下、この発明の実施の形態を図面とともに説明する。図１は実施形態１による移動電源車の要部斜視図を示し、蓋１３の両側面に円弧状の遮蔽部材１６，１７を取り付ける。その他の構成は従来と同様である。
【００１４】
上記構成の移動電源車においては、非運転中は遮蔽部材１６，１７は排気口３内に収納され、蓋１３は排気口３を閉じる。運転中は伸縮シリンダ１５の操作により蓋１３を抜き差しヒンジ１４を中心に回動し、排気口３を開く。
【００１５】
実施形態１においては、蓋１３の両側面に遮蔽部材１６，１７を設けたので、排気口３の側面のうち、蓋１３を設けた側及び遮蔽部材１６，１７を設けた側は遮音され、矢印で示す方向のみに車両１内の騒音は流出する。又、排気ガスや熱風も同一方向に流出する。
【００１６】
実施形態１においては、騒音等は排気口３から一方向にのみ流出するので、流出方向が限定され、騒音等の発生を極力少なくすることができる。
【００１７】
なお、蓋１３を排気口３の反対側に設けてもよい。又、発電機５をエンジン６により駆動したが、タービンにより駆動してもよい。
実施形態２（参考例２）
図２は実施形態２による移動電源車の要部斜視図を示し、蓋１３の一方の側面に遮蔽部材１７を設け、他方の側面には遮蔽部材を設けない。他の構成は従来と同様である。
【００１８】
実施形態２においては、蓋１３の一側面のみに遮蔽部材１７を設けている。従って、騒音等は矢印で示したように二方向へ流出するが、従来よりも流出方向が限定され、騒音等の発生を抑制することができる。
実施形態３（参考例３）
図３は実施形態３による移動電源車の要部斜視図を示し、１８，１９は蓋１３の抜き差しヒンジ１４側端部の両側部に一端が取り付けられ、蓋１３が開かれた状態で前方へ突出する一対の棒状支持部材であり、蓋１３の両側面には棒状支持部材１８，１９までの間にシート状の遮蔽部材２０，２１が設けられる。その他の構成は実施形態１と同様である。
【００１９】
実施形態３においては、遮蔽部材２０，２１をシート状にしただけであり、その他は実施形態１と同様であり、やはり騒音等の流出方向は矢印で示す一方向となり、騒音等の発生を極力抑制することができる。また、遮蔽部材２０，２１をシート状としたので、軽量で折りたたみ可能となる。
実施形態４（参考例４）
図４は実施形態４による移動電源車の要部斜視図を示し、２２は蓋１３の抜き差しヒンジ１４側端部の両側部に取り付けられ、蓋１３が開かれたとき前方に突出する枠状の支持部材であり、蓋１３の反抜き差しヒンジ１４側端部と枠状支持部材２２の先端との間にはシート状の遮蔽部材２３が取り付けられる。
【００２０】
実施形態４においては、蓋１３の抜き差しヒンジ１４側端部に設けられた枠状支持部材２２の先端と蓋１３の反抜き差しヒンジ１４側端部との間にシート状の遮蔽部材２３を設けており、蓋１３を開けたとき蓋１３と遮蔽部材２３により排気口３の二側面と上面が遮蔽される。このため、矢印に示す二方向にのみ騒音等が流出し、騒音等の流出を抑制することができる。この場合も遮蔽部材２３をシート状にしたので、軽量で折りたたみ可能となる。
【００２１】
なお、図４では、騒音等が二方向にのみ流出するようにしたが、例えば図４の構造に図２の遮蔽部材１７を組み合わせることによって、騒音等の流出方向を一方向に限定することもできる。この場合、遮蔽部材１７を図３のシート状遮蔽部材２１のようにしても同様の効果が得られる。
実施形態５
図５（ａ），（ｂ）は実施形態５による移動電源車の要部平面図及び要部正面図を示し、蓋１３は排気口３の一方の側（第１の辺）にヒンジ２４を介して開閉自在に設けられている。又、排気口３の蓋１３設置側と反対側（第２の辺）には遮蔽板２５がヒンジ２６を介して開閉自在に設けられている。前記蓋１３の一側部から前記遮蔽板２５の一側部に向けて前記通風口の第１の辺と第２の辺以外の第３の辺に沿って伸びる円弧状の第１の遮蔽部材２７が設けられ、前記遮蔽板２５の一側部から前記蓋１３の一側部に向けて前記第３の辺に沿って伸びて前記第１の遮蔽部材２７に重合する円弧状の第２の遮蔽部材２９が設けられ、前記蓋１３の他側部から前記遮蔽板２５の他側部に向けて前記通風口の前記第３の辺と対向する第４の辺に沿って伸びる円弧状の第３の遮蔽部材２８が設けられ、前記遮蔽板２５の他側部から前記蓋１３の他側部に向けて前記第４の辺に沿って伸びて前記第１の遮蔽部材２８に重合する円弧状の第４の遮蔽部材３０と、が設けられている。又、遮蔽板２５の上端にはリンク３１の一端がピン３２を介して回動自在に連結され、リンク３１の他端に形成した長孔３１ａに挿入されたボルト３３が蓋１３の下端に螺合される。又、遮蔽板２５の下端にもリンク３４の一端がピン３５を介して回動自在に連結され、リンク３４の他端に形成した長孔３４ａに挿入したボルト３６が蓋１３の上端に螺合される。さらに、リンク３１の中央に形成した長孔３１ｂにはリンク３４を挿通したピン３７が挿通される。
【００２２】
上記構成の移動電源車において、図示のように蓋１３及び遮蔽板２５を排気口３に対してほぼ直角に立設した状態では排気口３が開放され、この状態では排気口３の四方の側面は、蓋１３、遮蔽板２５、遮蔽部材２７，２９及び遮蔽部材２８，３０により遮蔽され、排気口３から流出した騒音はこれらの部材により遮蔽され、水平方向には流出せず、上方にのみ流出する。排気ガスや熱風も同様である。又、ボルト３３，３６を緩めると、蓋１３及び遮蔽板２５を内側へ倒すことができ、排気口３は閉じられる。
【００２３】
実施形態５においては、騒音、排気ガス、熱風は水平方向には流出せず、上方へのみ流出するので、周辺住民等への影響を極力抑制することができる。なお、遮蔽板２５、及び遮蔽部材２７〜３０の内側に吸音材を貼着してもよい。
【００２４】
【発明の効果】
以上のようにこの発明の請求項１によれば、騒音、排気ガス、熱風は水平方向には流出せず、上方へのみ流出するので、周辺住民等への影響を極力抑制することができる。
