Abstract

L'invention a pour objet un procédé de contrôle de l'étanchéité d'un objet (1), de préférence une batterie électrique (1), présentant au moins une cavité étanche, dans lequel on utilise un drone (10, 10a, 10b, 10c) comprenant des moyens de commande et des moyens de détection d'obstacles, le procédé comprenant les étapes suivantes : - brancher un conduit de raccordement (5) entre une source d'un gaz traceur (3) et la cavité étanche de l'objet (1) à contrôler, - remplir ladite cavité avec le gaz traceur à une pression supérieure à la pression atmosphérique, - déployer un drone (10, 10a, 10b, 10c) suivant une trajectoire couvrant au moins une partie de la surface extérieure de l'objet à contrôler, ledit drone étant équipé en outre de moyens de détection du gaz traceur. Une installation est également associée au procédé.The subject of the invention is a method for checking the tightness of an object (1), preferably an electric battery (1), having at least one sealed cavity, in which a drone (10, 10a, 10b is used , 10c) comprising control means and obstacle detection means, the method comprising the following steps: - connecting a connecting pipe (5) between a source of a tracer gas (3) and the sealed cavity of the 'object (1) to be checked, - fill said cavity with the tracer gas at a pressure greater than atmospheric pressure, - deploy a drone (10, 10a, 10b, 10c) along a trajectory covering at least part of the outer surface of the object to be inspected, said drone being furthermore equipped with means for detecting the tracer gas. An installation is also associated with the process.
