Description

Technical Field

[0001] The utility model relates to the technical field of fireproof doors, in particular to a heat-insulating fireproof door. 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 a certain degree of fire resistance, installed between fire compartments, evacuation stairwells, vertical shafts, etc. Fire doors generally still maintain the function of passage under normal circumstances. They only have a certain degree of isolation when a fire occurs, reducing the probability of fire spreading and providing a barrier for people to escape.

[0003] Traditional fire doors have gaps around them to allow air to circulate on both sides of the door. In the event of a fire, the circulating air will cause the fire to spread. When the flame spreads to both sides of the fire door, the flame will burn the fire door, causing the temperature of the fire door to be too high, affecting the trapped people's independent escape. For this reason, we propose an insulated fire door. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-5 As shown, a heat-insulating fireproof door comprises a door body 1 rotatably mounted on a door frame, a docking block 2 is embedded in the wall of the door body 1 on one side away from the door frame, a receiving box 3 is embedded in the wall of the door body 1 on one side close to the door frame, a protective door 9 used in conjunction with the docking block 2 is slidably mounted in the receiving box 3, a rack plate 5 is fixedly mounted on the upper end surface of the protective door 9, and a driving gear 4 meshingly connected to the rack plate 5 is rotatably mounted on the upper end of the receiving box 3 at a position corresponding to the rack plate 5;

[0026] When a fire occurs, the smoke sensor installed on the door body 1 will activate the internal emergency response system after sensing the smoke. The entire insulated fire door is powered by an independent battery. After receiving the signal, the smoke sensor transmits the signal to the controller (CPM1A PLC controller). The controller controls the driving gear 4 to rotate and then drives the protective door 9 as a whole to slide out from the inside of the containing box 3 through the meshing action with the rack plate 5. When one end of the protective door 9 slides to the inside of the docking block 2 and contacts the inner wall of the docking block 2, the protective door 9 stops sliding. At this time, the position of the protective door 9 can protect the entire door body 1, and use the protective door 9 as a dividing line to block the fire, preventing the fire from further spreading to the other side of the door body 1.

[0027] like Figure 3As shown, an auxiliary platform 7 is provided on the bottom surface of the door body 1, and the auxiliary platform 7 is embedded in the ground of the bottom surface of the door body 1. A groove is provided on the upper end surface of the auxiliary platform 7 at a position corresponding to the protective door 9, and a clearance groove 14 is provided on the inner wall on one side of the groove. A dustproof plate 11 is slidably installed inside the clearance groove 14. When the door body 1 is in normal use, the end of the dustproof plate 11 slidably installed inside the clearance groove 14 is clamped in the inner wall on the other side of the groove, and the dustproof plate 11 can block the open upper end of the groove to prevent external garbage and dust from falling into the groove, so as to ensure that the lower end of the protective door 9 can slide normally inside the groove when a fire occurs.

[0028] like Figure 3 and Figure 5 As shown, a spray assembly 8 is provided on the upper end face of the door body 1, and a contact sensor is provided at the end of the outer wall of the spray assembly 8 close to the protective door 9. When the protective door 9 slides out from the interior of the containing box 3, the edge of the protective door 9 squeezes the contact sensor and the nozzle on the spray assembly 8 automatically sprays water. The nozzle is located directly above the door body 1 and the protective door 9. After the water in the spray assembly 8 is sprayed outward, the door body 1 and the protective door 9 can be cooled, and at the same time, the fire can be prevented from further spreading to the space on the other side of the door.

[0029] like Figure 5 As shown, an installation box 12 is provided inside the groove, and an electric telescopic rod is fixedly connected to the bottom surface of the installation box 12, and the other end of the electric telescopic rod is fixedly connected to the bottom surface of the groove, and a plurality of rollers 10 are rotatably installed inside the installation box 12; the position of the installation box 12 can be adjusted under the control of the electric telescopic rod, and after the position of the installation box 12 is adjusted, the outer wall of the rotating roller 10 inside the installation box 12 can contact the bottom surface of the protective door 9, so that when the protective door 9 slides, the rotating roller 10 can assist the protective door 9 to slide quickly to the specified position.

[0030] like Figure 5 As shown, a driving wheel 13 is rotatably installed at one end of the installation box 12 close to the protective door 9, a rubber pad is fixedly installed on the outer wall of the driving wheel 13, and a driving motor is fixedly installed at the outer wall of the installation box 12 and the corresponding position of the driving wheel 13, and the output end of the driving motor is fixedly connected to the center position of the driving wheel 13; when a fire occurs, the driving gear 4 rotates to drive the protective door 9 to slide outside the wall, and at the same time, the driving wheel 13 located at the lower end of the protective door 9 and contacting the lower end surface of the protective door 9 rotates under the drive of the driving motor, which can accelerate the sliding of the protective door 9 outward, and the rubber pad arranged on the outer wall of the driving wheel 13 can increase the friction between the outer wall of the driving wheel 13 and the bottom surface of the protective door 9, thereby enhancing the auxiliary effect of the driving wheel 13 on the protective door 9 when the driving wheel 13 rotates.

[0031] like Figure 5As shown, two symmetrically arranged supporting blocks 6 are fixedly installed inside the end of the storage box 3 away from the door body 1, and a plug-in rod 15 used in conjunction with the supporting block 6 is fixedly installed on the outer wall of the protective door 9 on the side close to the supporting block 6. When the protective door 9 is not in use and is stored inside the storage box 3, the two plug-in rods 15 are both inserted into the gap between the supporting block 6 and the wall, so as to support one side of the protective door 9.

[0032] like Figure 5 As shown, the width of the protective door 9 is not less than the width of the door body 1, and the upper end surface of the protective door 9 is higher than the upper end surface of the door body 1, and the lower end surface of the protective door 9 is not higher than the lower end surface of the door body 1. The overall size of the protective door 9 is larger than the door body 1. When the protective door 9 is in a closed state, the protective door 9 can provide all-round protection for the door body 1 and can seal the gaps on the side of the door body 1 to prevent air circulation from causing the fire to spread when a fire occurs.

[0033] The working principle of the utility model is as follows: when in use, the entire heat-insulating fireproof door is powered by an independent battery. When the smoke sensor arranged on the door body 1 receives the smoke signal, the protective door 9 can be driven to rotate by driving the driving gear 4 so as to slide out of the interior of the storage box 3. The protective door 9 is made of fireproof material. After one end of the protective door 9 slides into the interior of the docking block 2, the lower end of the protective door 9 is stuck in the groove provided on the upper surface of the auxiliary platform 7. At this time, the protective door 9 can separate the space on both sides thereof to prevent the fire from spreading further. When the protective door 9 slides out of the storage box 3, the protective door 9 squeezes the contact sensor arranged on the spray assembly 8, and the spray assembly 8 is opened to spray water into the gap between the door body 1 and the protective door 9. The water sprayed from the spray assembly 8 can cool down the door body 1 and the protective door 9 on the one hand, and extinguish part of the flames spreading outward from the corresponding side of the door body 1 on the other hand. When the rescue personnel arrive at the scene, the protective door 9 can be pulled by an external tool to make it slide back into the interior of the storage box 3 to avoid affecting the rescue personnel to open the door body 1 to rescue the people in the room.

[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
