AI Technical Summary
The existing normally closed steel fire doors cannot be sunlight in the partition area, and it is difficult for escapees to quickly locate the fire doors due to salt mist at the fire site.
A fire-proof door with both lighting and guidance and escape was designed, using a fire-resistant glass door leaf main body and a thermally conductive metal door leaf frame. The main body of the door leaf is equipped with a storage chamber and a liquid storage tank. High boiling point flame retardant liquid and high-reflection particles are stored in the liquid storage tank. The thermally deformed material baffle melts during a fire, allowing liquid to enter the door leaf main body. The high-reflection particles reflect light under the action of the luminescent ceramic layer, making the door leaf main body luminous.
Provide lighting function during daily use. When a fire occurs, the main body of the door leaf will shine, helping the escapees quickly position the fire door and ensure a smooth escape.

Description
Technical Field
[0001] The invention relates to the technical field of fire doors, in particular to a fire door with the functions of both lighting and escape guidance. Background Art
[0002] Fire doors refer to doors that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. They are fireproof partitions with certain fire resistance, located between fire compartments, evacuation stairwells, vertical shafts, etc.
[0003] Most existing fire doors are normally closed steel doors. When in the normally closed state, the separated area cannot be illuminated through the location of the fire door. On the other hand, during a fire, salt mist is diffuse, blocking the line of sight. Escaping personnel often miss the opportunity to escape due to low visibility and inability to quickly locate the fire door. Summary of the invention
[0004] The technical problem to be solved by the present invention is to provide a fire door that can both provide lighting and guide escape, thereby solving the problem that the separated areas of the existing normally closed steel fire doors cannot be illuminated, and that escapees cannot quickly locate the position of the fire door at a fire scene filled with salt fog.
[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: Fire doors that provide both lighting and escape guidance, including door leaf bodies and door leaf frames; The door leaf body is in the shape of a rectangular parallelepiped, and is made of fireproof glass. The door leaf body is provided with a receiving cavity, and a liquid inlet is provided at the upper part of the receiving cavity; and light-storing material layers are provided at the upper, lower, left and right sides of the receiving cavity respectively. The door leaf frame is connected to the upper, lower, left and right sides of the door leaf body, and includes an upper frame, in which a liquid storage tank is provided, in which high-boiling-point flame-retardant liquid and highly reflective particles are stored, and a liquid discharge port is provided at the accommodating cavity relative to the liquid inlet, and a baffle with a thermally deformable material is connected between the liquid inlet and the liquid discharge port, and the material of the upper frame is a heat-conducting metal.
[0006] Furthermore, in the above-mentioned fire door structure with both lighting and escape guidance functions, the thermally deformable material is specifically polypropylene.
[0007] Furthermore, in the above-mentioned fire door structure that has both lighting and escape guidance functions, the thickness of the thermally deformable material is less than 1 mm.
[0008] Furthermore, in the above-mentioned fire door structure with both lighting and escape guidance functions, a sealing ring is provided at the liquid inlet and a sealing ring is provided at the liquid discharge outlet.
[0009] Furthermore, in the above-mentioned fire door structure having both lighting and escape guidance functions, the high boiling point flame retardant liquid is selected from triethyl phosphate.
[0010] Furthermore, in the above-mentioned fire door structure with both lighting and escape guidance functions, the highly reflective particles are specifically nano-silicon dioxide particles.
[0011] Furthermore, in the above-mentioned fire door structure having the functions of both lighting and guiding escape, the material of the light-storing material layer is luminescent ceramic.
[0012] Furthermore, in the above-mentioned fire door structure that has both lighting and escape guidance, a slot for inserting and removing a blocking piece is provided between the liquid inlet and the liquid discharge port of the upper frame, one section of the blocking piece blocks between the liquid inlet and the liquid discharge port, and the other section of the blocking piece extends to the outside of the upper frame, and the surface of the portion of the blocking piece extending to the outside of the upper frame is provided with a light-storing material layer.
[0013] The beneficial effects of the present invention are as follows: when it is used as a corridor partition fire door in daily life, it is in a normally closed state, and external light can be transmitted to one side of the partition through the fireproof glass material of the door leaf main body, so that one side of the partition can obtain sufficient lighting. When a fire occurs on one side of the partition, the temperature rises sharply, causing the baffle to soften due to the heat, thereby losing the sealed partition between the drain port and the liquid inlet, allowing the high-boiling point flame retardant liquid and highly reflective particles in the liquid storage tank to enter the accommodating cavity of the door leaf main body through the liquid inlet, so that the highly reflective particles are dispersed in the accommodating cavity. Under the luminous effect of the light-storing material layer, the highly reflective particles reflect light, so that the entire door leaf main body appears in a luminous state, and the large area of luminous area enables escapees to quickly locate the position of the fire door through the smoke for smooth escape.

DETAILED DESCRIPTION
[0015] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.
[0016] Please refer to Figures 1 to 8 , a specific embodiment of the present invention relates to a fire door with both lighting and escape guidance, including a door leaf body 1 and a door leaf frame 2; The door leaf body is in the shape of a rectangular parallelepiped. The door leaf body 1 is made of fireproof glass. The door leaf body 1 is provided with a receiving cavity 11. A liquid inlet 12 is provided at the upper part of the receiving cavity 11. Light-storage material layers 13 are provided at the upper, lower, left and right sides of the receiving cavity 11. The door leaf frame 2 is connected to the upper, lower, left and right sides of the door leaf body 1. The door leaf frame 2 includes an upper frame 21. A liquid storage tank 22 is provided in the upper frame 21. The liquid storage tank 22 stores high-boiling point flame retardant liquid and highly reflective particles. The accommodating cavity 11 is provided with a drain port 23 relative to the liquid inlet 12. A baffle 24 with a thermally deformable material is connected between the liquid inlet 12 and the drain port 23. The material of the upper frame 21 is a heat-conducting metal, preferably copper.
[0017] In the above embodiment, when it is used as a corridor partition fire door in daily life, it is in a normally closed state, and external light can be transmitted to one side of the partition through the fireproof glass material of the door leaf main body 1, so that one side of the partition can obtain sufficient lighting. When a fire occurs on one side of the partition, the temperature rises sharply, causing the baffle 24 to soften due to the heat, thereby losing the sealed partition between the drain port 23 and the liquid inlet 12, allowing the high-boiling point flame retardant liquid and highly reflective particles in the liquid storage tank 22 to enter the accommodating cavity 11 of the door leaf main body 1 through the liquid inlet 12, so that the highly reflective particles are dispersed in the accommodating cavity 11. Under the luminous effect of the light-storing material layer 13, the highly reflective particles reflect light, so that the entire door leaf main body 1 appears to be luminous, and the large area of luminous area enables escapees to quickly locate the position of the fire door through the smoke for smooth escape.
[0018] Preferably, the heat-deformable material is polypropylene, and the heat deformation temperature of polypropylene is 70-80°C. When a fire occurs on one side of the corridor, the ambient temperature rises sharply in a relatively closed environment. Since the upper frame 21 is made of a high thermal conductivity material, the upper frame 21 will quickly heat up to above 80°C, which is higher than the ambient temperature, and the baffle 24 made of polypropylene will soften through heat transfer.
[0019] Preferably, the thickness of the heat-deformable material is less than 1 mm, preferably 0.5 mm. The thickness of the heat-deformable material should not be too thick, otherwise it will take too long to soften due to heat, resulting in the failure of the heat-deformable material to melt and deform in time when a fire occurs, causing the highly reflective particles and high-boiling point flame retardant liquid to flow into the accommodating cavity 11 of the door leaf body 1 in time. In theory, the thinner the heat-deformable material is, the better, but a certain thickness is required to ensure its structural strength before melting and deformation, so as to avoid the baffle 24 from losing its barrier to the liquid inlet 12 and the liquid outlet 23 due to vibration.
[0020] Preferably, a sealing ring is provided at the liquid inlet 12 and a sealing ring is provided at the liquid discharge port 23. When no fire occurs, the baffle 24 is blocked between the liquid discharge port 23 and the liquid inlet 12 by the sealing rings connected up and down, thereby maintaining the sealing and preventing the liquid in the liquid storage chamber from entering the accommodating chamber 11.
[0021] Preferably, the high boiling point flame retardant liquid is selected from triethyl phosphate.
[0022] Preferably, the highly reflective particles are specifically nano-silicon dioxide particles.
[0023] Preferably, the light-storage material layer 13 is made of luminescent ceramics.
[0024] Preferably, a slot for inserting and removing a blocking piece 24 is provided between the liquid inlet 12 and the liquid discharge port 23 of the upper frame 21, one section of the blocking piece 24 blocks between the liquid inlet 12 and the liquid discharge port 23, and the other section of the blocking piece 24 extends to the outside of the upper frame 21. The surface of the portion of the blocking piece 24 extending to the outside of the upper frame 21 is provided with a light-storing material layer 13.
[0025] In the above structure, one section of the baffle 24 blocks between the liquid inlet 12 and the liquid discharge port 23, and the other section of the baffle 24 extends to the outside of the upper frame 21. On the one hand, the baffle 24 can contact the upper frame 21 made of heat-conducting metal material, so that the high temperature accumulated in the upper frame 21 can be quickly transmitted to the baffle 24, so that the baffle 24 can melt and deform more sensitively during a fire, so that the highly reflective particles and the high-boiling-point flame retardant liquid can quickly flow into the accommodating chamber 11. On the other hand, in the early stage of a fire, when the fire has not spread to the location of the fire door, the baffle 24 can also be manually pulled out to artificially make the highly reflective particles and the high-boiling-point flame retardant liquid quickly flow into the accommodating chamber 11, which is convenient for the subsequent positioning of escapees. The surface of the part of the baffle 24 extending to the outside of the upper frame 21 is provided with a light-storage material layer 13, which is convenient for escapees to quickly locate the position of the baffle 24.
[0026] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent transformations made using the contents of the present invention's specification and drawings, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.
