Abstract

La présente invention concerne un rouleau de dispositif de transport présentant une fonction de pulvérisation, comprenant : un corps de rouleau creux ; un arbre inséré dans le corps de rouleau et à l'intérieur duquel est formée une partie creuse destinée à renfermer un agent d'extinction ; un palier prévu entre le corps de rouleau et l'arbre pour supporter à rotation le corps de rouleau par rapport à l'arbre ; un élément formant buse accouplé à l'arbre de manière à communiquer avec la partie creuse de l'arbre ; et un élément de blocage prévu dans l'arbre pour empêcher l'agent d'extinction contenu dans la partie creuse d'être introduit dans l'élément formant buse, l'agent d'extinction s'échappant vers l'extérieur par l'élément formant buse lorsque l'élément de blocage est rompu. En cas de surchauffe ou d'incendie, le rouleau de dispositif de transport peut pulvériser l'agent d'extinction de façon à empêcher la surchauffe et à éteindre promptement le feu, et même s'il est installé dans un endroit difficile d'accès, le rouleau de dispositif de transport peut éteindre un feu de manière autonome.
