Description

【０００１】
【発明の技術分野】
本発明は、直交軸型水中モータポンプを用いた着脱式ポンプ設備、例えばマンホールやゲートポンプ設備などにおける吸込口および吐出口の接離機構に関するものである。
【０００２】
【従来技術とその問題点】
従来、脱着式ポンプ設備においては図3および図４に示すよう、下面に吸込口１２０を有し側面に吐出口１３０を有する全周水路型同軸軸流ポンプ１６０Ａや渦巻きポンプ１６０Ｂを用い、貯留槽１００内に立設された昇降ガイド５００に沿って上記ポンプが下降したとき、吐出口１３０の上方部に付設された係止爪１５０が送出口３００のフランジ上縁部に係止して、吐出口１３０のフランジ面が送出口３００のフランジ面へ衝合し、ポンプは着脱ベンド２００の後方へ片持状に連結された荷重バランスの悪い態様となる。
【０００３】
そして図３のような全周水路型同軸軸流ポンプ１６０Ａを用いた場合には、該ポンプの引き上げ時に係止爪１５０の係止部が支点となってポンプ下方部が矢示方向へ持ち上るように回動する。従ってその回動量に見合ったスペースがポンプ後方部に必要となり、マンホールや、ゲートポンプ設備のように貯留槽の前後壁間の間隔が制約されている場所には不適当である。また、図４のような渦巻きポンプ１６０Ｂの場合は、係止爪１５０の係止部からポンプ中心線までの距離が長く且つ該中心線の上方部にポンプ重心が存在するため、上記係止部を支点としたテコの作用が矢示方向に働き、フランジ衝合面の上方部に間隙ｇを生じて圧洩れを招来するという欠点がある。
【０００４】
【発明の目的】
本発明の目的は、ポンプ装着時にはフランジ衝合面が緊密に圧接して圧洩れを生じることなく、且つ荷重バランスが良好で昇降作動が円滑に行われてその操作性に優れ、引き上げ時にはポンプが垂直姿勢を保持したままで上昇させられてポンプ後方部に余分なスペースを必要とせず、マンホールやゲートポンプ設備など、貯留槽の前後壁間の間隔が大きく取れない場所で有効に機能する、直交軸型水中モータポンプを用いた着脱式ポンプ設備における吸込口および吐出口の接離機構を提供することにある。
【０００５】
【発明の構成】
本発明に係る直交軸型水中モータポンプを用いた着脱式ポンプ設備における吸込口および吐出口の接離機構では側開型の吸込口と吐出口を背向状に開口させた直交軸型水中モータ軸流ポンプが、その吸込口および吐出口の双方または何れか一方のフランジ面を下傾状のテーパー面に形成させてあり、貯留槽内へ通じる流入口および排出口の双方または何れか一方のフランジ面が、前記下傾状のテーパー面に適応する上傾状のテーパー面に形成され、直交軸型水中モータポンプを挟み込むよう、該ポンプ正面側の中心線上とその反対面側に位置するように、貯溜槽内へ縦設された昇降ガイドに沿って直交軸型水中モータポンプを下降させることにより、該ポンプの吸込口および吐出口のフランジ面が前記流入口および排出口のフランジ面へクサビ作用で圧接し、引き上げ時には直交軸型水中モータポンプが垂直姿勢を保持したまま昇降ガイドに沿って上昇し、該ポンプの吸込口および吐出口のフランジ面が前記流入口および排出口のフランジ面から離隔するよう構成した。
【０００６】
【実施例】
以下実施例の図１および図２により説明をする。
【０００７】
１はマンホールやゲートポンプ設備など流入水の貯留および排出に供せられる貯留槽（ゲート本体）、２は貯留槽１の前壁面に設けられた流入口、３は貯留槽１の後壁面に設けられた排出口、４は排出口３に付設された逆止弁、５は直交軸型水中モータポンプ６を挟み込むよう、該ポンプ６正面側の中心線上とその反対面側に位置するように、貯留槽１内に縦設された昇降ガイドである。前記昇降ガイド５に係合子７を係合させて昇降する直交軸型水中モータポンプ６であって、堅型水中モータ８の下方にプロペラ９を収容したガイドリング１０が横設状に結合されており、モータ主軸の回転が歯車機構を介してプロペラ軸に伝達され、ガイドリング１０の両端開口面は側開型の吸込口１２および吐出口１３にそれぞれ形成されている。そして吸込口１２および吐出口１３の双方または何れか一方のフランジ面を下傾状のテーパー面１６ａに形成し、貯留槽１内へ通じる流入口２および排出口３の双方または何れか一方のフランジ面が、前記下傾状のテーパー面１６ａに適応する上傾状のテーパー面１６ｂに形成されている。図１および図２の実施例では、吸込口１２のフランジ面を下傾状のテーパー面１６ａに形成し、流入口２のフランジ面を上記下傾状のテーパ面１６ａに適応する上傾状のテーパー面１６ｂに形成させてあり、吐出口１３と排出口３とは鉛直面で対向するよう形成されている。また、使用される直交軸型水中モータポンプとしては、実施例の図面に示された直交軸型水中モータ軸流ポンプの他に直交軸型水中モータ斜流ポンプとすることもできる。
【０００８】
【作用】
昇降ガイド５に沿った直交軸型水中モータポンプ６の下降限において、該ポンプの吸込口１２および吐出口１３のフランジ面が、貯留槽（ゲート本体）１内の流入口２および排出口３のフランジ面へ、ポンプの自重とテーパー面１６ａ，１６ｂによるクサビ作用で緊密に圧接し、衝合面の封水性を高めるよう作用する。また、二点支承により荷重バランスが良好に保たれ、引き上げ時には、直交軸型水中モータポンプ６は垂直姿勢を保持したままで、昇降ガイド５に沿って貯留槽（ゲート本体）１内を上昇し、吸込口１２および吐出口１３のフランジ面が、流入口２および排出口３のフランジ面から離隔する。
【０００９】
【発明の効果】
本発明によれば、ポンプ装着時にはポンプ自重がテーパー面に加わるので、クサビ作用を生じて衝合面の封水性が高められ、ポンプ運転時における衝合面からの圧洩れを防止することができる。そして従来のような片持状連結ではなく、二点支承により荷重バランスが良好に保たれていてポンプの昇降操作を円滑に行うことができ、引き上げ時にはポンプが垂直姿勢を保持したままで上昇するため、ポンプ後方部に余分なスペースを必要とせず、従ってマンホールやゲートポンプ設備など、貯留槽の前後壁間の間隔を大きく取れない場所で有効に機能するという利点がある。
