[0021] Embodiment: Please refer to Figures 1-6, a fireproof and explosion-resistant sliding door for explosion-proof area isolation, comprising a door frame 1. The inner cavity of the door frame 1 is rotatably connected with a sliding door 2 through a hinge. A sealing component 6 is arranged on the outer side of the sliding door 2. The sealing component 6 penetrates through the sliding door 2 and extends into the inner cavity of the sliding door 2. Explosion-proof components 3 are arranged on the opposite sides of the sliding door 2 and the sealing component 6. A door closer 4 is fixedly connected to the outer side of the explosion-proof component 3, and the explosion-proof component 3 is fixedly connected to the door frame 1 through the door closer 4. A temperature reduction component 7 is arranged in the inner cavity of the sliding door 2. The temperature reduction component 7 is connected to the sealing component 6. A spray head 8 is arranged on the outer side of the explosion-proof component 3. The spray head 8 is connected to the temperature reduction component 7 through a connecting pipe. Among them, in order to facilitate the use of the device, a handle 5 is fixedly connected to the outer side of the explosion-proof component 3.

[0022] The explosion-proof component 3 includes a honeycomb energy-absorbing structure 31 fixedly connected to the outer sides of the sliding door 2 and the sealing component 6. The honeycomb energy-absorbing structure 31 is composed of a metal composite material. When the hexagonal units of the honeycomb structure are subjected to an explosion shock wave, through the plastic deformation of the unit walls, the concentrated shock energy is gradually dispersed throughout the structure. Each unit is like a miniature "energy trap", consuming the shock kinetic energy through deformation to avoid the concentrated transfer of energy to the inner layer of the door body. At the same time, compared with a solid steel plate, the honeycomb structure can significantly reduce the weight of the door body under the same explosion-proof performance. And an explosion-proof steel plate 32 is fixedly connected to the outer side of the honeycomb energy-absorbing structure 31. The thickness of the explosion-proof steel plate 32 is 20 mm and a bulletproof coating is arranged on the outer side. The 20-mm-thick honeycomb energy-absorbing structure 31 absorbs and disperses the initial shock energy through a high yield strength of more than 500 MPa and a ductile deformation ability, significantly reducing the energy transmitted to the internal structure. The bulletproof coating can increase the surface hardness of the honeycomb energy-absorbing structure 31 to above HRC60, causing the fragments to break rather than penetrate when hitting, and the elastic coating absorbs the kinetic energy of the fragments through deformation, reducing the shear stress on the honeycomb energy-absorbing structure 31.

[0023] By setting the explosion-proof component 3, when the device is subjected to an explosion shock wave, the explosion-proof steel plate 32 is responsible for bearing the initial shock pressure and blocking large-sized fragments, while the honeycomb energy-absorbing structure 31 focuses on absorbing the remaining energy, forming a gradient protection system of "hard shell - soft core", thereby dispersing the shock wave generated by the explosion and improving the explosion-proof effect of the device. And by setting the honeycomb energy-absorbing structure 31 in a honeycomb shape, the overall weight of the device can be significantly reduced under the same explosion-proof performance, improving the practical performance of the device.

A turntable 69 is arranged on the outer side of the connection column 68. A second guiding groove 610 is formed through the outer side of the turntable 69, and the turntable 69 is movably connected to the connection column 68 through the second guiding groove 610. A driving assembly is arranged on the side of the turntable 69 away from the fixed disk 62. The driving assembly includes a rotating shaft 613 rotatably connected to the inner wall of the sliding door 2. One end of the rotating shaft 613 penetrates through the sliding door 2 and is fixedly connected to the turntable 69, and the other end of the rotating shaft 613 is fixedly connected to a worm gear 614. A worm 615 is meshed with the outer side of the worm gear 614. Both ends of the worm 615 are rotatably connected to bearing brackets 616. The bearing brackets 616 are fixedly connected to the sliding door 2. One end of the worm 615 penetrates through the bearing bracket 616 and is fixedly connected to a driving shaft 617. A gear 618 is fixedly connected to the end of the driving shaft 617 away from the worm 615. A rack 619 is meshed with the outer side of the gear 618. A cross plate 612 is fixedly connected to the lower side of the rack 619. High-temperature expanded graphite 611 is placed below the cross plate 612.

[0025] By arranging the sealing assembly 6, when a fire occurs in the device, the high-temperature expanded graphite 611 can be heated and expanded, so that the turntable 69 drives the connection column 68 to move through the second guiding groove 610, and further the connection column 68 drives the sealing block 67 to expand outwards through the movable rod 66, so as to seal the gap between the sliding door 2 and the door frame 1, avoiding the diffusion of smoke during a fire through the gap between the sliding door 2 and the door frame 1, and improving the safety performance of the device.

[0026] The cooling component 7 includes a water tank 71 fixedly connected to the inner wall of the sliding door 2. The water tank 71 is communicated with a spray head 8 through a connecting pipe. The bottom of the inner cavity of the water tank 71 is rotatably connected with a threaded rod 72. The bottom end of the threaded rod 72 penetrates through the water tank 71 and is connected with a transmission component. The outer side of the threaded rod 72 is threadedly connected with a threaded sleeve 73. The top end of the threaded sleeve 73 is fixedly connected with a water pushing plate 74. A guide cylinder 75 is fixedly connected below the water pushing plate 74. A guide rod 76 is slidably connected in the inner cavity of the guide cylinder 75. The guide rod 76 is fixedly connected with the water tank 71. The transmission component includes a mounting bracket 78 fixedly connected to the inner wall of the sliding door 2. A linkage shaft 77 is rotatably connected to the outer side of the mounting bracket 78. One end of the linkage shaft 77 is fixedly connected with the threaded rod 72. The other end of the linkage shaft 77 is fixedly connected with a driven gear 79. A driving gear 710 is meshed with the outer side of the driven gear 79. A mounting shaft 711 is fixedly connected to the outer side of the driving gear 710. The mounting shaft 711 penetrates through a bearing bracket 616 and is fixedly connected with a worm 615.

[0027] By arranging the cooling component 7, when the device seals the gap between the sliding door 2 and the door frame 1, the rotation of the threaded rod 72 can be automatically controlled, so that the water pushing plate 74 can sprinkle the water above it on the surface of the explosion-proof steel plate 32 through the spray head 8, so as to cool the door body and avoid increasing the difficulty of subsequent rescue due to the too high temperature of the door body, thereby further improving the practical performance of the device.

[0028] The working principle of the present invention: When the door body receives the explosion shock wave, the honeycomb energy absorption structure 31 absorbs and disperses the initial shock energy through a high yield strength of more than 500 MPa and a ductile deformation ability, significantly reducing the energy transmitted to the internal structure. And the kinetic energy of the fragments is absorbed through the deformation of the elastic coating. For the remaining shock wave, the hexagons of the honeycomb structure disperse the concentrated shock energy layer by layer to the whole structure through the plastic deformation of the metal honeycomb unit wall. Each unit is like a micro "energy trap", consuming the shock kinetic energy through deformation and avoiding the concentrated transmission of energy to the inner layer of the door body; When a fire breaks out, the fire temperature can cause the high-temperature expanded graphite 611 to expand due to heat, so that the high-temperature expanded graphite 611 drives the cross plate 612 to move upward. When the cross plate 612 moves, it will drive the rack 619 fixedly connected to it to move synchronously, so that the rack 619 drives the gear 618 meshed with it to rotate. When the gear 618 rotates, it will drive the drive shaft 617 fixedly connected to it to rotate, so that the drive shaft 617 drives the worm 615 fixedly connected to it to rotate. When the worm 615 rotates, it will drive the worm gear 614 meshed with it to rotate, so that the worm gear 614 drives the rotating shaft 613 fixedly connected to it to rotate. When the rotating shaft 613 rotates, it will drive the turntable 69 fixedly connected to it to rotate, so that the turntable 69 drives the connecting column 68 to move through the second guiding groove 610. When the connecting column 68 moves, it will drive the movable plate 64 fixedly connected to it to move outward, so that the movable plate 64 drives the arc plate 65 fixedly connected to it to move synchronously. When the arc plate 65 moves, it will drive the movable rod 66 fixedly connected to it to expand outward, so that the movable rod 66 drives the sealing block 67 fixedly connected to it to move synchronously. When the sealing block 67 moves, it will seal the gap between the sliding door 2 and the door frame 1 through the gasket to prevent the diffusion of smoke; When the worm 615 rotates, it will drive the mounting shaft 711 fixedly connected to it to rotate, so that the mounting shaft 711 drives the driving gear 710 fixedly connected to it to rotate. When the driving gear 710 rotates, it will drive the driven gear 79 meshed with it to rotate, so that the driven gear 79 drives the linkage shaft 77 fixedly connected to it to rotate. When the linkage shaft 77 rotates, it will drive the threaded rod 72 fixedly connected to it to rotate, so that the threaded rod 72 drives the threaded sleeve 73 threadedly connected to it to move upward. When the threaded sleeve 73 moves, it will drive the water pushing plate 74 fixedly connected to it to move synchronously, so that the water pushing plate 74 sprays the water above it on the explosion-proof steel plate 32 through the nozzle 8 to cool the door body and prevent the temperature of the door body from being too high, which may increase the difficulty of subsequent rescue.
