[0002] With the rapid development of my country's economy, various types of buildings have emerged rapidly. Fire doors, as fire separation facilities, have been widely used in buildings. Fire doors have the function of preventing the spread of fire and smoke, and are an important guarantee for the safe evacuation of personnel in the event of a fire. Fire doors are installed in fire compartments, evacuation stairwells, vertical shafts and other places. They are fire partitions with a certain degree of fire resistance. Normally open fire doors are kept open at ordinary times to facilitate the passage of personnel and can be used for fire evacuation in the event of a fire; normally closed fire doors must always be in a closed state to effectively block the invasion of thick smoke and fire after a fire occurs.
[0003] Most of the current emergency fire doors are designed without a threshold. The design without a threshold can avoid tripping when people are evacuating, but there will be a certain gap between the door surface and the ground. This gap reduces the overall sealing of the emergency fire door, thereby reducing the smoke blocking ability and affecting the safety of the safe area behind the door. Utility Model Content

DETAILED DESCRIPTION
[0020] The utility model is described in detail below in conjunction with the accompanying drawings.
[0021] See also Figures 1 to 4 This embodiment provides an emergency fire door, including a door frame 1, a pair of fireproof door faces 2 connected to the door frame 1 by hinge rotation, and a pair of door closers 3 arranged on the door frame 1 and the pair of fireproof door faces 2; the door closer 3 can make the fireproof door faces 2 have the effect of automatic door closing. A caulking groove 4 is arranged at the bottom of each fireproof door face 2, and a fireproof cotton strip 5 is inserted in the caulking groove 4, and the fireproof cotton strip 5 extends to the ground; the fireproof strip 5 is used to fill the gap between the fireproof door face 2 and the ground, and meet certain fire resistance at this position. A water immersion structure 6 is arranged in the caulking groove 4, and the water immersion structure 6 includes a liquid passing groove 61 opened on one side of the inner wall of the caulking groove 4, a water passing pipe 62 detachably installed at the end of the liquid passing groove 61, and a plurality of overflow holes 63 opened on the water passing pipe 62. In the utility model, a threaded joint is provided at one end of the water pipe 62, which is threadedly detachably connected to the liquid-passing groove 61 through the threaded joint to facilitate assembly; the water pipe 62 is inserted into the fireproof cotton strip 5; the arrangement of the water pipe 62 inserted into the fireproof cotton strip 5 allows the fireproof cotton strip 5 to be soaked in water, which can reduce the air permeability of the fireproof cotton strip 5 to increase the sealing between the fireproof door surface 2 and the ground; at the same time, the fireproof cotton strip 5 in the water-soaked state can further improve the fire resistance. The end of the liquid-passing groove 61 away from the water pipe 62 extends to the front surface of the fireproof door surface 2, and a water supply structure 7 connected to the liquid-passing groove 61 is provided on the fireproof door surface 2. A smoke detection module for controlling the water supply structure 7 to supply water to the water pipe 62 is also provided on the fireproof door surface 2.
[0022] In this embodiment, a fireproof cotton strip 5 is arranged between the fireproof door face 2 and the ground to fill the gap between the fireproof door face 2 and the ground. The fireproof cotton strip 5 reduces its own air permeability by being immersed in water, which can effectively reduce the air permeability of the gap between the fireproof door face 2 and the ground, that is, improve the sealing of the gap, thereby effectively providing protection against smoke circulation for the safe area behind the fireproof door face 2.
[0023] A limiting block 9 is integrally arranged in the caulking groove 4, and a limiting groove 10 is arranged on the fireproof cotton strip 5, which is plugged into and cooperates with the limiting block 9; the plug-in cooperation between the limiting groove 10 and the limiting block 9 allows the fireproof cotton strip 5 to be arranged in the caulking groove 4 in a plug-in manner, which can meet the flexibility of the use of the fireproof cotton strip 5.
[0024] A notch 12 is provided at the corner of the fireproof cotton strip 5, and the notch 12 is located at the bottom of the fireproof door surface 2; the setting of the notch 12 can ensure that the fireproof cotton strip 5 is effectively in contact with the ground, while making the caulking groove 4 set at the bottom of the fireproof door surface 2 a local setting state, thus providing a setting interval for the liquid passing groove 61.
[0025] The fireproof cotton strip 5 is provided with a plug hole 11 for plugging with the water conduit 72. The plug hole 11 on the fireproof cotton strip 5 can be plugged into the water conduit 72 when the fireproof cotton strip 5 is inserted into the caulking groove 4. In this way, when water flows in the water conduit 72, water can drip onto the fireproof cotton strip 5 from the overflow hole 63 to wet the waterproof cotton strip 5 and reduce its air permeability. In addition, due to the plug-in cooperation between the water conduit 72 and the fireproof cotton strip 5, the fireproof cotton strip 5 can be prevented from falling off when the fireproof door surface 2 moves.
[0026] The water supply structure 7 includes a water tank 71, a water pipe 72 fixedly connected to the bottom of the water tank 71, and a solenoid valve 73 arranged on the water pipe 72. One end of the water pipe 72 is connected to one end of the liquid trough 61. In the utility model, a water inlet is arranged on the top of the water tank 71; the water pipe 72 in the utility model can be detachably connected to the liquid trough 61 through a flexible joint, and the water tank 71 can be installed on the fireproof door surface 2 through screws.
[0027] The smoke detection module includes a smoke sensor 8, and the output end of the smoke sensor 8 is electrically connected to the input end of the solenoid valve 73. The smoke sensor 8 is used to detect whether there is smoke around the fireproof door surface 2, so as to timely control the water supply structure 7 to drip water to the fireproof cotton strip 5, so as to meet the timeliness of sealing the gap between the fireproof door surface 2 and the ground.
[0028] Specifically, when the smoke sensor 8 on the fireproof door surface 2 detects the presence of smoke, it can control the solenoid valve 73 on the water pipe 72 to be in an open state; the water in the water tank 71 can pass through the water pipe 72, the liquid tank 61, and the water pipe 62 in sequence, and when the water flows into the water pipe 62, the overflow hole 63 thereon can provide an overflow channel to immerse the fireproof cotton strip 5, so that the fireproof cotton strip 5 can be soaked with water. The soaked fireproof cotton strip 5 can reduce its own air permeability, so that the gap between the fireproof door surface 2 and the ground can be effectively blocked, which can effectively reduce the flow of smoke through the gap. At the same time, the soaked fireproof cotton strip 5 can further improve the fire resistance, thereby enhancing the protective performance of the fire door.
