Title
(EN) HOLDER DEVICE FOR MARINE ANODES
(FR) DISPOSITIF DE SUPPORT POUR ANODES MARINES
Abstract
(EN)
A holder device for a marine anode (2) which is mounted to ship's cladding plates to prevent or reduce their corrosion, by connection to the ship's side (10) of protruding end parts (8) of anode carrier irons (6) preferably embedded in the anode (2), consists of a steel body (12) which is adapted to be welded onto the exterior of the ship's side (10), and which is shaped with a hollow (14) which is open to receive one of the said end parts (8) of the anode carrier iron (6), and in connection with the said hollow (14), the holder device includes clamping means (16) which are arranged to retain the said end part (8) and to establish an efficient conductive connection between the said end part of the anode carrier iron (6) and the ship's side (10). In this way it becomes possible to attain a substantial facilitation and reduction of cost in changing marine anodes, as the change can be made in a relatively short time by a diver without the ship needing to visit a yard or to be docked.
(FR)
La présente invention se rapporte à un dispositif de support pour une anode marine (2), qui est montée sur les tôles de placage recouvrant la coque du bateau pour empêcher ou atténuer leur corrosion par fixation au flanc (10) du bateau de pièces terminales saillantes (8) de fers porte-anode (6) de préférence noyés dans l'anode (2). Un tel dispositif de support se compose d'un corps en acier (12) qui est conçu pour être soudé sur l'extérieur du flanc (10) du bateau et qui présente un évidement ouvert (14) destiné à recevoir l'une des pièces terminales (8) du fer porte-anode (6) et, en relation avec l'évidement (14), le dispositif de support comprend des organes de boulonnerie (16) qui servent à retenir la pièce terminale (8) et à établir une liaison conductrice efficace entre la pièce terminale du fer porte-anode et le flanc (10) du bateau. De cette façon, on facilite sensiblement les opérations de changement des anodes marines et on en réduit le coût, dès lors que ce changement peut être effectué par un plongeur dans un temps relativement court, sans qu'il soit nécessaire de conduire le bateau au chantier ou de l'amarrer à quai.
