Abstract

L'invention concerne un ensemble couvercle flottant pour un réservoir de stockage comprenant un couvercle flottant intérieur et un couvercle flottant extérieur qui sont reliés de façon à former une ossature radiale au moyen d'éléments en acier en forme de I et de boulons. Ces éléments en acier en forme de I sont constitués par des plaques d'acier ou d'aluminium. Le couvercle flottant intérieur et le couvercle flottant extérieur sont reliés à une plaque centrale par six poutres radiales. Des éléments circulaires extérieurs et des éléments circulaires intérieurs sont reliés par des éléments périphériques. Des éléments de fixation des plaques de couvercles sont situés sur les poudres radiales et reliés par des éléments auxiliaires. Des flotteurs en plastique, en forme de triangles équilatéraux ou de rectangles, sont placés dans tous les espaces de l'ossature. Un flotteur épais est fixé sur l'élément circulaire extérieur et sur l'élément circulaire intérieur. Les plaques de couvercles s'étendent sur des éléments de fixation appropriés et sont comprimées par des barres de compression. Un ruban adhésif d'étanchéification en forme de languette et un ruban adhésif d'étanchéification sacciforme présentent deux plis. L'ensemble couvercle flottant selon l'invention empêche l'huile d'être polluée ou détériorée. En outre, il est relativement léger de sorte qu'il réduit la consommation de matériau métallique nécessaire, ne coule pas et ne peut pas se bloquer.
