Under the normal non-fire condition, the opening and closing functions of the intelligent sound barrier in each area can be independently controlled through a remote controller, and instructions do not need to be issued through the central management system 4. During equipment maintenance, when a system breaks down and is powered off (the door opener is in an unlocking state during power off), the intelligent sound barrier opening and closing function can be realized through a manually opened device, so that equipment can enter and exit.
When the intelligent sound barrier 1 fails, is fierce in fire and the like and cannot be opened under other conditions, the particle noise reduction plate in the intelligent sound barrier 1 can be softened and melted under the action of high temperature so as to fall off at high temperature, and the function of opening the sound barrier can also be realized; the particle noise reduction plate is stable and reliable in structure under the non-fire condition, and in the initial stage of fire (the temperature inside the plate is less than or equal to 200 ℃), the particle noise reduction plate is slowly softened in a continuous high-temperature environment, the rigidity is weakened, and the particle noise reduction plate is in an outward convex or outward raised edge state. When a fire disaster enters a middle stage (the temperature inside the plate is 200-250 ℃), the particulate noise reduction plate finally loses rigidity completely along with the continuous rise of the environmental temperature, and the particulate noise reduction plate is broken under the action of self weight to be changed into a plurality of fragments to fall downwards. The double-safety structure can ensure the realization of the opening function of the sound barrier to the maximum extent.
The board of making an uproar can be smashed into tiny fragment to fall the process particle that drops, and tiny fragment still can be broken once more when dropping subaerial even, finally can present the disintegrating slag subaerial, and the powder state can not form sheltering from, covering to equipment conflagration ignition point to can not influence the fire extinguishing operation of fire engine, the fire engine can be accurate put out a fire to the flame root, has improved the accuracy and the efficiency of putting out a fire greatly.
The above examples are intended to be illustrative of possible embodiments of the invention and are not intended to limit the scope of the invention, which is intended to be covered by the claims unless the invention is modified or practiced in a manner that is equivalent to the practice of the invention or otherwise applied to a fire fighting environment other than that of the converter, but which is also intended to meet the fire fighting requirements.
