La présente invention a, en conséquence, la réalisation d'une pompe manuelle permettant le pompage de l'eau située à des profondeurs importantes, cette pompe ne nécessitant par ailleurs pas d'entretien et étant, de ce fait, d'une très grande fiabilité. The present invention therefore has the production of a manual pump for pumping water located at great depths, this pump also requiring no maintenance and therefore being very large. reliability.
Cette pompe comprend un corps de pompe cylindrique 1 qui est immergé dans l'eau se trouvant dans le fond d'un forage 2 réalisé dans le sol. Ce cylindre est obturé à ses extrémités inférieure et supérieure par des disques 3 et 4 fixés par vissage. Le disque d'obturation inférieur 3 est pourvu d'un clapet à bille 31 permettant l'introduction de l'eau dans le cylindre 1 par l'intermédiaire d'une crépine 32. Le disque supérieur 4 est pourvu de deux raccords 41 et 42 qui se prolongent à l'intérieur du corps de pompe 1 par des parties tubulaires respectivement 43 et 44. This pump comprises a cylindrical pump body 1 which is immersed in the water located in the bottom of a borehole 2 made in the ground. This cylinder is closed at its lower and upper ends by discs 3 and 4 fixed by screwing. The lower sealing disc 3 is provided with a ball valve 31 allowing the introduction of water into the cylinder 1 via a strainer 32. The upper disc 4 is provided with two connections 41 and 42 which extend inside the pump body 1 by tubular parts 43 and 44 respectively.
Le raccord 41 comporte un clapet à bille interdisant le retour de l'eau à l'intérieur du corps de pompe 1. The connector 41 includes a ball valve preventing the return of water inside the pump body 1.
Ces raccords 41, 42 sont chacun reliés à un tuyau 5 et 6. Le tuyau 5 débouche à la surfacé du sol dans une borne-fontaine 7 et forme en 8 l'orifice de sortie de l'eau pompée. These connections 41, 42 are each connected to a pipe 5 and 6. The pipe 5 opens to the surface of the ground in a standpipe 7 and forms at 8 the outlet orifice for the pumped water.
Le tuyau 6 est fixé à la base d'un cylindre de commande 9 à l'intérieur duquel se déplace un piston 10 lui-même entraîné à partir d'un bras de manoeuvre 11 pivotant sur un axe 12 de la borne 7. Ce bras de manoeuvre 11 est relié au piston 10 par une tringlerie 13 qui est articulée en 131 sur le bras de manoeuvre 11 et qui est reliée par une rotule 132 au piston 10. The pipe 6 is fixed to the base of a control cylinder 9 inside which moves a piston 10 itself driven from an operating arm 11 pivoting on an axis 12 of the terminal 7. This arm operating lever 11 is connected to the piston 10 by a linkage 13 which is articulated at 131 on the operating arm 11 and which is connected by a ball joint 132 to the piston 10.
Le piston 10 est lui-meme réalisé en matière plastique et reçoit dans des rainures annulaires des segments 101 également en matière plastique. The piston 10 is itself made of plastic and receives in annular grooves segments 101 also made of plastic.
La rotule 132 de la tige 13 est fixée dans le fond d'un logement axial 102 du piston par l'intermédiaire d'une bague 14 pourvue d'une portée sphérique 141 maintenue dans le logement 102 par une bague élastique logée dans une rainure 103. The ball joint 132 of the rod 13 is fixed in the bottom of an axial housing 102 of the piston by means of a ring 14 provided with a spherical bearing 141 held in the housing 102 by an elastic ring housed in a groove 103 .
Dans cette pompe, le corps de pompe 1, ses disques d'extrémité 3, 4, les raccords 419 42 les tuyauteries 5, 6, le cylindre 9, le piston 10 et les segments 101 seront réalisés en matière plastique afin d'être totalement insensibles à l'action corrosive de l'eau. In this pump, the pump body 1, its end discs 3, 4, the fittings 419 42 the pipes 5, 6, the cylinder 9, the piston 10 and the segments 101 will be made of plastic to be completely insensitive to the corrosive action of water.
La borne-fontaine 7 est réalisée en métal convenablement protégé contre la rouille et elle supporte le cylindre 9 sur une platine 15 également traversée par la partie supérieure du tuyau 5.The standpipe 7 is made of metal suitably protected against rust and it supports the cylinder 9 on a plate 15 also crossed by the upper part of the pipe 5.
Le fonctionnement -de cette pompe est le suivant. The operation of this pump is as follows.
Lorsque l'actionnement du bras 11 provoque la descente du piston 10 dans le cylindre 9, l'air initialement contenu dans le cylindre est refoulé dans la tuyauterie 6 et son prolongement 44 afin de s'évacuer par le clapet 4 la tuyauterie 5 et l'orifice 8. Lorsque le piston 10 remonte dans le cylindre, le clapet 31 s'ouvre et de l'eau pénètre dans le corps de pompe 1 en remontant également dans le tuyau 6 et le cylindre 9. Au mouvement de descente suivant du piston 10, celui-ci refoule alors l'eau dans le corps de pompe 1 de façon que cette eau soit refoulée dans le tuyau 5 par l'intermédiaire du clapet 4 Cette eau s'écoule alors par l'orifice 8. When the actuation of the arm 11 causes the piston 10 to descend into the cylinder 9, the air initially contained in the cylinder is discharged into the piping 6 and its extension 44 in order to be evacuated by the valve 4 the piping 5 and l orifice 8. When the piston 10 rises in the cylinder, the valve 31 opens and water enters the pump body 1, also rising in the pipe 6 and the cylinder 9. At the following downward movement of the piston 10, the latter then discharges the water into the pump body 1 so that this water is discharged into the pipe 5 via the valve 4. This water then flows through the orifice 8.
On constate donc que cette pompe peut s'amorcer seule même si au départ le tuyau 6 et le cylindre 9 ne contiennent que de l'air. I1 suffira en effet d'actionner plusieurs fois le bras de manoeuvre 11 pour que le tuyau 6 et le cylindre 9 soient totalement remplis d'eau pour obtenir le débit constant. It can therefore be seen that this pump can prime itself even if at the start the pipe 6 and the cylinder 9 contain only air. I1 will be sufficient to actuate the operating arm 11 several times so that the pipe 6 and the cylinder 9 are completely filled with water to obtain the constant flow rate.
