Title (EN) MAGNETIC RETRIEVAL TOOL
(FR) OUTIL DE RÉCUPÉRATION MAGNÉTIQUE
Abstract:
(EN) A magnetic retrieval tool for retrieving devices, such as probes, from a pressurized system. The retrieval tool uses a magnetic coupling to transfer movement of an external mechanism (i.e. external to the pressurized system), such as by an operator's manual movement, a motor or other drive, to an internal mechanism (i.e. internal to the pressurized system). The magnetic coupling may be through a wall of a pressure vessel using an outer magnetic core coupled to the outside of the pressure vessel which magnetically couples to an inner magnetic core disposed on the inside of the pressure vessel, such that translational or rotational movement of the outer magnetic core cause substantially simultaneous and corresponding translational and/or rotational movement of the inner magnetic core. An end effector tool is coupled to the inner magnetic core to engage and retrieve or insert the device into the pressurized system.
(FR) La présente invention concerne un outil de récupération magnétique pour récupérer des dispositifs, tels que des sondes, à partir d'un système pressurisé. L'outil de récupération utilise un couplage magnétique pour transférer le mouvement d'un mécanisme externe (c'est-à-dire externe au système pressurisé), par exemple à l'aide d'un mouvement manuel d'opérateur, d'un moteur ou d'un autre dispositif d'entraînement, vers un mécanisme interne (c'est-à-dire interne au système pressurisé). Le couplage magnétique peut se faire à travers une paroi d'une cuve sous pression en utilisant un noyau magnétique externe couplé à l'extérieur de la cuve sous pression qui se couple magnétiquement à un noyau magnétique interne disposé sur l'intérieur de la cuve sous pression, de telle sorte qu'un mouvement de translation ou de rotation du noyau magnétique externe provoque un mouvement sensiblement simultané et correspondant de translation et/ou de rotation du noyau magnétique interne. Un outil d'effecteur d'extrémité est couplé au noyau magnétique interne afin de venir en prise avec le dispositif dans le système pressurisé, afin de récupérer ou d'insérer ledit dispositif dans ledit système pressurisé.
