Description

Technical Field

[0002] Fire doors are doors with fire resistance. They block the air flow between two spaces in case of fire, prevent the spread of thick smoke, toxic gases and hot air, and resist fire for a certain period of time, delaying or controlling the spread of fire. Therefore, fire doors play a vital role in the event of fire. At present, fire doors are widely used in many fields such as residential houses, ships, construction, chemical industry, mechanical engineering, etc. Commonly used fire doors are steel metal doors, which can effectively prevent the spread of fire by taking advantage of the high melting point of metal.

[0003] In the prior art, when the existing steel fire doors are in use, when the indoor temperature is too high and the fire spreads to the fire doors, the fire cannot be extinguished in time at the door, which is not convenient for people to escape in time, and the heat insulation effect is poor. When a fire occurs, it is easy for the steel fire doors to absorb heat quickly, making their heat insulation performance low, which is easy to cause harm to trapped people, making it inconvenient for people to use, reducing the practicality of steel fire doors.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0019] The following is combined with Figure 1-3 This application is described in further detail.

[0020] The present application embodiment discloses a steel heat-insulating fireproof door. Figure 1 A steel heat-insulating fireproof door, on the outer surface of the door frame 1, a plurality of connecting plates 7 are fixedly connected at its four corners, on the outer surface of the door frame 1, a motor 8 is fixedly connected through the connecting plates 7 on both sides, on the outer surface of the door frame 1, two threaded rods 10 are rotatably connected through a plurality of connecting plates 7 on both sides, the driving ends of the motors 8 penetrate the inner walls of the connecting plates 7 and are fixedly connected to one side of the threaded rods 10, on the outer surface of the door frame 1, a limiting rod 9 is fixedly connected through a plurality of connecting plates 7 on one side of the corresponding threaded rods 10, and on the outer wall of the threaded rod 10, a connecting block 11 is threadedly connected through one side thereof.

[0021] Reference Figure 1 and Figure 2 , the two connecting blocks 11 are fixedly connected to the opposite sides with atomizing nozzles 13, and liquid storage chambers 15 are opened on both sides of the interior of the door frame 1. On the side surface of the door frame 1, hoses 12 are connected on both sides. On the side surface of the door frame 1, the two sides are connected with the connecting blocks 11 through the hoses 12 respectively, and the motors 8 on both sides drive the threaded rods 10 to rotate at the same time, and are connected to the connecting blocks 11 through the limit rods 9. The connecting blocks 11 are connected to the threaded rods 10, so that the moving direction of the connecting blocks 11 is limited by the limit rods 9, and then the connecting blocks 11 are driven to rise and fall along the outer wall of the limit rods 9 by the rotation of the threaded rods 10, and the liquid in the liquid storage chamber 15 is transported to the connecting blocks 11 through the hoses 12, and sprayed from the atomizing nozzles 13, thereby driving the atomizing nozzles 13 on both sides to rise and fall at the same time and spray liquid on the outside of the door frame 1, so that the temperature is reduced to facilitate the escape of personnel, thereby achieving the effect of facilitating the escape of personnel.

[0022] Reference Figure 1 On the inner wall of the door frame 1, a fire door body 2 is hinged on both sides, and on the outer surface of the door frame 1, door closers 3 are arranged on both sides, and the door closers 3 are connected to the fire door body 2. On the outer surface of the door frame 1, a controller 5 is fixedly connected on one side, and the door frame 1 and the fire door body 2 are connected through the door closer 3, so that after people escape, the fire door body 2 automatically closes to block the fire, thereby achieving the effect of preventing the fire from spreading.

[0023] Reference Figure 1On the outer surface of the door frame 1, a smoke alarm 6 is arranged on one side thereof, and on the outer surface of the door frame 1, a temperature sensor 4 is arranged on one side corresponding to the smoke alarm 6. In the interior of the door frame 1, fireproof expansion seals 14 are arranged on both sides thereof. The two fireproof expansion seals 14 enable the fire door body 2 to effectively block the smoke from flowing to the escape passage after the door is closed. The fire occurring outside the door frame 1 is detected by the temperature sensor 4 and the smoke alarm 6. When the temperature is high, the temperature sensor 4 and the smoke alarm 6 transmit signals to the controller 5. The controller 5 controls the motors 8 on both sides to start and drive the threaded rod 10 to rotate, and then drives the connecting block 11 to reciprocate up and down, so that the temperature of the door frame 1 is cooled by spraying liquid through the atomizing nozzle 13, thereby achieving the effect of facilitating people to escape through the door frame 1.

[0024] Reference Figure 3 On the outer surface of the fire door body 2, basalt fiber boards 18 are arranged on both sides thereof, in the interior of the fire door body 2, ceramic fiber boards 17 are arranged on the side corresponding to the basalt fiber boards 18, and in the interior of the fire door body 2, a glass fiber board 16 is arranged at the center position thereof. Through the mutual cooperation of the glass fiber board 16, the ceramic fiber board 17 and the basalt fiber board 18, the steel fire door body 2 is prevented from absorbing heat quickly and its thermal insulation performance is not low, so that the fire door body 2 has a good flame retardant effect when in use, thereby improving the practicality of the steel fire door body 2.

[0025] The implementation principle of a steel insulated fire door in an embodiment of the present application is as follows: a fire occurring outside the door frame 1 is detected through a temperature sensor 4 and a smoke alarm 6. When the temperature is high, the temperature sensor 4 and the smoke alarm 6 transmit signals to a controller 5. The controller 5 controls the motors 8 on both sides to start and drive the threaded rod 10 to rotate. The threaded rod 10 is connected to the threaded rod 10 through a connecting block 11. The moving direction of the connecting block 11 is limited by a limiting rod 9. Then, the threaded rod 10 is rotated to drive the connecting block 11 to rise and fall along the outer wall of the limiting rod 9. The hose 12 facilitates the liquid in the liquid storage chamber 15 to be transported to the connecting block 11 and sprayed out from the atomizing nozzle 13, thereby driving the atomizing nozzles 13 on both sides to rise and fall at the same time and spray liquid on the outside of the door frame 1, thereby cooling the temperature outside the door frame 1.
