The specific implementation process is as follows:
reach the purpose of fire prevention through door plant 11 and insulating layer 21, insulating layer 21 can obstruct the intensity of a fire and spread promptly, when the indoor explosion or other impact that take place that catches fire, strengthens supporting door plant 11 and insulating layer 21 through reinforcing plate 31, improves door plant 11's pressure-bearing capacity.
The existing door panel 11 has poor sealing performance, and even the sealing part of the door panel 11 can be burnt under the condition of large fire, so that the sealing purpose is difficult to achieve. In this embodiment, when the door panel 11 and the heat insulating layer 21 cannot block fire, the heat absorbent absorbs heat from the door panel 11 and the heat insulating layer 21, so as to reduce the possibility of fire of the door panel 11 and the heat insulating layer 21. When the heat absorbing agent is heated and boiled, a large amount of water vapor is generated, under the action of the water vapor, the sealing block 33 is pushed and slides towards the sealing plate 51, and under the pressure action of the sealing block 33, the sealing plate 51 moves towards the gap between the door panel 11 and the wall body, so that the purpose of sealing the gap is achieved, and harmful gas in a firing chamber is prevented from entering an unfired chamber.
In this embodiment, when a fire is to be extinguished in a room, the fire extinguishing shaft 37 drives the rotating plate 38, and the rotating plate 38 drives the baffle 32 to be offset from the fire extinguishing hole 13, so that the fire extinguishing hole 13 communicates with the nozzle 39. Then fire extinguishing liquid is fed into the fire extinguishing chamber 36 through the fire extinguishing shaft 37, for example, a fire extinguisher is communicated with the fire extinguishing shaft 37, fire extinguishing agent is fed into the fire extinguishing chamber 36, the fire extinguishing agent is sprayed towards the fire extinguishing holes 13 through the fire extinguishing chamber 36 and the fire extinguishing nozzles 39, and the fire extinguishing range is expanded through the fire extinguishing holes 13 due to the fact that a plurality of fire extinguishing holes 13 are arranged. Of course, the fire extinguishing shaft 37 may be connected to a water source, and water may be used as the fire extinguishing agent for fire extinguishing purposes.
In this embodiment, as shown in fig. 3, if a fire breaks out in the room on the left side of the door panel 11, the operator can feed the fire extinguishing agent from the right side of the fire extinguishing shaft 37, and only the electrically controlled spray head 39 on the left side is opened, so that the fire extinguishing agent is not sprayed from the fire extinguishing hole 13 on the right side. On the contrary, if a fire breaks out in the room on the right side of the door panel 11, the operator can send the fire extinguishing agent from the left side of the fire extinguishing shaft 37, and only the electrically controlled spray head 39 on the right side is opened, so that the fire extinguishing agent is not sprayed out from the fire extinguishing hole 13 on the right side, that is, the present embodiment achieves the purpose of extinguishing fire on both sides.
In this embodiment, as shown in fig. 4, when the fire extinguishing hole 13 is opened, the fire extinguishing shaft 37 drives the rotating plate 38, and then the rotating plate 38 drives the baffle 32 to rotate, the baffle 32 pushes the closing plates 51 at both sides, so that the closing plates 51 close the gap between the door panel 11 and the wall, and harmful gas is prevented from entering the room without fire.
After finishing putting out a fire, when driving baffle 32 through axle 37 and rotor plate 38 and reseing (baffle 32 no longer offsets with closing plate 51 this moment, can drive closing plate 51 and reseing under the effect of spring 52, and the indoor a large amount of harmful gas still exists after putting out a fire, so lead to harmful gas can enter into not catching fire indoor, can pass through this moment, the water heat absorption boiling in the heat absorption chamber 34 produces a large amount of vapor, with closing block 33 continuously compressing tightly closing plate 51 under the effect of vapor, closing plate 51 continues to seal the clearance between door plant 11 and the wall body, avoid harmful gas to enter into not catching fire indoor, wait to cool the water back in the heat absorption chamber 34, closing block 33 resets under the effect of gravity, closing plate 51 resets under the effect of spring 52.
In this embodiment, a heater may be further installed in the heat absorption cavity 34, and if the water in the heat absorption cavity 34 is not boiled, the heat absorbing agent is heated by the heater to boil the water and generate a large amount of water vapor, so as to ensure that the closing plate 51 closes the gap between the door panel 11 and the wall.
