Title (EN) UNDERGROUND WATER PUMPING DEVICE
(FR) DISPOSITIF DE POMPAGE D'EAU SOUTERRAINE
Abstract: front page image
(EN)An underground water pumping device capable of effectively performing a water collecting/water pumping operations with a relatively simple structure and effectively utilizing an existing deep well device, comprising an outer tube buried in the ground and an inner tube having a length generally equal to that of the outer tube and disposed in the outer tube through a clearance provided therebetween, a shielding member for shielding the upper end part of the outer tube from the upper end part of the inner tube, a decompressing means for reducing a pressure in the inner tube, and a pumping means for pumping up the underground water came from the underground water inlet into the inner tube, the outer tube further comprises a water passing part at the lower part thereof and the inner tube further comprises an underground water inlet at the lower end part thereof, wherein the underwater inlet is positioned under the upper end part of the water passing part.
(FR)L'invention se rapporte à un dispositif de pompage d'eau souterraine permettant de recueillir ou de pomper efficacement de l'eau au moyen d'une structure relativement simple et d'utiliser efficacement un dispositif existant de puits profond. Ledit dispositif de pompage comporte un tube externe enterré dans le sol et un tube interne ayant une longueur généralement égale à celle du tube externe et disposé à l'intérieur dudit tube externe dans un vide ménagé entre les deux tubes, un élément de protection conçu pour isoler la partie terminale supérieure du tube externe de la partie terminale supérieure du tube interne, un moyen de décompression conçu pour réduire la pression dans le tube interne, et un moyen de pompage conçu pour pomper l'eau souterraine passant de l'orifice d'entrée pour eau souterraine vers l'intérieur du tube interne. Par ailleurs, ledit tube externe comporte en sa partie inférieure une zone de passage de l'eau et le tube interne comprend au niveau de sa partie terminale inférieure un orifice d'entrée de l'eau souterraine, ledit orifice d'entrée de l'eau souterraine étant positionné en dessous de la partie terminale supérieure de la zone de passage de l'eau.
