COMBINATION OF AN OBJECT FOR PROTECTING AND A FIRE-FIGHTING DEVICE, AND METHOD FOR TARGETED PROTECTION

摘要

Combination (20) of an object for protecting (5) and a fire-fighting device (21), comprising a spray nozzle (1,2) with an outflow opening (10), a heat-sensitive element (11) and a curved surface (12), characterized in that the object for protecting, the heat-sensitive element and the curved surface are placed relative to each other and the curved surface is of a form such that radiant heat from the object for protecting is directed selectively onto the heat-sensitive element by means of the curved surface. If the object for protecting, the outflow opening and the curved surface are also placed relative to each other and the curved surface is also of a form such that fire-extinguishing material leaving the outflow opening is directed selectively onto the object for protecting by means of the curved surface, the object for protecting can be guarded in targeted manner and sprayed with extinguishing material in targeted manner. The invention also provides a method for targeted protection of an object for protecting (5) by means of such a fire-fighting device (21).
