Description
この実施の形態による空気混入防止装置は、図6に示すような渓流取水設備に設置され、図1に示すように、第1の導水路10と第2の導水路20とを備えている。なお、この実施の形態では、先に説明した図6と同一または同一と見なされる構成要素には、それと同じ参照符号を付けてその説明を省略する。
この実施の形態では、図3に示すように、実施の形態1による導水管21〜23の取入れ口21A〜23Aの設置位置を階段状にしている。この場合、この実施の形態では、図4に示すように、取水路110を流れる水Wの落下点、つまり落下する水Wの量が最多と想定される位置に導水管21が在る場合、導水管21の取入れ口21Aを、第1の導水路10の取入れ口11から距離L11の位置に配置し、水Wの落下量が少なくなると想定される位置に導水管22が在る場合、導水管22の取入れ口22Aを、第1の導水路10の取入れ口11から距離L12の位置に配置する。そして、水Wの落下量が最も少ないと想定される位置に導水管23が在る場合、導水管23の取入れ口23Aを、第1の導水路10の取入れ口11から距離L13の位置に配置する。
距離L11>距離L12>距離L13
の関係となるように調整する。これにより、導水管21の取入れ口21A、導水管22の取入れ口22A、導水管23の取入れ口23Aの順に、第1の導水路10の取入れ口11に対して近づくように、取入れ口21A〜23Aが段差を形成している。

Claims (1)
- 渓流から取水した水を流す取水路に対して連結された立坑内に、前記取水路からの水をすべて取り入れる第1の導水路を備える空気混入防止装置において、
前記第1の導水路内に設置され、前記取水路からの水を複数の細流にして流す第2の導水路を備え、前記第2の導水路は、複数の導水管により形成され、かつ、前記取水路からの水を取り入れる前記各導水管の取入れ口が段差を形成するように配置されていることを特徴とする空気混入防止装置。
