Description
また、前記膨張機及び発電機を単一の格納箱内に収納設置したパッケージ型の発電装置が公知となっている(例えば、特許文献1参照)。
また、スクロール型流体機械を格納箱に収納設置したユニット装置であって、前記スクロール型流体機械の下部に空冷用通風ダクトを設け空冷用ファンの吸気側に接続した装置が公知となっている(例えば、特許文献2参照)。
ここで、図2に示すように、格納箱22は、矢印Aの方向を前方として定義する。
まず、発電装置1の構成について図1のブロック図を用いて説明する。
発電装置1は、蒸気により駆動される膨張機2と、膨張機2の出力軸43に連結されて駆動される発電機3と、蒸気発生器4と、作動媒体供給ポンプ6と、凝縮器8と、制御装置50と、を有する。
発電装置1を構成する膨張機2、発電機3、及び制御装置50は、台座21の上に載置されて格納箱22に収納される。
フレーム27は、台座21に立設された縦フレーム27aと、縦フレーム27aの上端及び中途部を接続する複数本の横フレーム27bとから構成される。本実施形態においては、縦フレーム27aは四本設けられており、それぞれの下端が台座21の上面に立設されている。四本の縦フレーム27aは平面視で長方形の頂点に位置するよう配置されており、それぞれの頂点を結ぶ長方形の辺上に横フレーム27bが横設されている。横フレーム27bは、水平方向と平行に横設されており、縦フレーム27aの上端と上端及び中途部と中途部とを接続するように配置されている。
網板31は、格納箱22において膨張機2の上方の天井部に開口された通気用孔を覆うように設けられている。本実施形態では天井よりも一回り小さい四角形状の通気用孔の内側に網板31の外周が固設されている。この網板31によりゴミや虫等の異物が侵入するのを防止する。
防護屋根32は、網板31の上方及びその周囲を覆うように設けられており、防護屋根32の外周は下方に折り曲げ形成された縁部が設けられ、格納箱22の天井部を覆うとともに、前記縁部は天井部と防護屋根32との間の隙間よりも下方に延設されて、側方より雨等が浸入しないように構成されている。なお、縁部の内側面と格納箱22の外側面との間にも隙間が設けられている。
格納箱22は、仕切り部材30によって、制御装置50が格納される側(以下、制御装置50側)と、膨張機2と、発電機3とが格納される側(以下、膨張機2側)と、の二つの空間に仕切られる。即ち、仕切り部材30は台座21の前後中途部から上方に立設され、格納箱22を板体により前後二つの空間に仕切り、前側を制御装置50の格納室とし、後側を膨張機2と発電機3の格納室としている。
これにより、発電機3を台座21から離間させた状態で固定させることができる。また、螺子の位置を長孔27dの上下長さの範囲内で上下させることにより、発電機3の上下位置を調整させることが可能となり、後述するベルト48の張りを調節できる。
作動媒体タンク25は、凝縮器8によって凝縮され液体となった水を一時的に貯溜するためのタンクである。
また格納箱22外に設けられた蒸気発生器4から膨張機2へ高温高圧の蒸気を供給するための作動媒体通路12は、格納箱22の側面上部から膨張機2側の空間にかけて配置されており、その一端が膨張機2に連結されている。
作動媒体供給ポンプ6の前端には、図示せぬパイプが設けられており、前記パイプは外部の作動媒体通路15へと連通している。
まず、膨張機2を長孔27eの一番下端で横フレーム27bに固定し、出力プーリ47と入力プーリ42との間にベルト48を巻回する。次に、図5の二点鎖線で示すように、膨張機2を固定している螺子を緩め長孔27eの一番上方に螺子を移動させて膨張機2を上方へ移動させる。これにより、ベルト48の張力が高まる。次に膨張機2を移動させた場所で再び螺子を締めて横フレーム27bに固定する。このように構成することにより、ベルト48の張力調節が容易となる。
また、長孔27dの中途部に螺子を移動させて発電機3を固定した場合には、発電機3の自重により発電機3が下方へ移動するため、ベルト48に張力が生まれる。これにより、ベルト48の張力を調整する作業を簡易化することができる。
このように構成することにより、膨張機2を容易に格納箱22の外側へ移動させることができるので、効率よく膨張機2のメンテナンスを行うことが可能となる。
このように構成することにより、煙突効果により、下から上へ向けて空気が流れるため、膨張機2、発電機3、及び制御装置50を効率よく冷却することができる。また、膨張機2及び発電機3を台座21から離間させたことにより、空気が流れる通路が広くなるため、膨張機2、発電機3、及び制御装置50を効率よく冷却することができる。また、膨張機2及び発電機3を台座21から離間させたことにより、膨張機2及び発電機3をメンテナンスする際の空間が生まれ、メンテナンスを効率よく行うことができる。また、上方から雨などの異物が入り込むのを防止し、耐久性を向上させて、メンテナンス作業を省くことができる。
このように構成することにより、煙突効果の薄い制御装置50側においても下から上へ向けて空気が流れやすくなるため、膨張機2、発電機3、及び制御装置50を更に効率よく冷却することができる。
このように構成することにより、膨張機2及び発電機3を台座21から離間させたことにより、膨張機2及び発電機3をメンテナンスする際の空間が生まれ、メンテナンスを効率よく行うことができる。また、発電機3の自重によってベルト48に張力が生まれるため、ベルト48の張力を調整する作業を簡易化することができる。
このように構成することにより、膨張機2及び発電機3を台座21から離間させたことにより、膨張機2及び発電機3をメンテナンスする際の空間が生まれ、メンテナンスを効率よく行うことができる。また、膨張機2を上下に移動させて固定することによって、ベルト48の張力を調整する作業をすることができ、作業を簡易化することができる。
