[0002] Fire doors are doors that can meet the requirements of fire resistance stability, integrity, and heat insulation for a certain period of time. They are installed in fire compartments, evacuation stairwells, vertical shafts, and other places. They are fire-resistant partitions with a certain degree of fire resistance and play a role in preventing the spread of fire and smoke. They can stop the spread of fire for a certain period of time and ensure the evacuation of people. Nowadays, fire door designs are used in a wide range of fields, and most doors in residential buildings also have fire-resistant effects.

[0003] To prevent fire from spreading through safety passages during a fire, fire doors need to be installed in the walls of these passages. To enhance fire resistance, double-layered steel plate staggered fire doors are required. However, existing double-layered steel plate staggered fire doors, while designed for fire protection, are prone to deformation under high temperatures during large fires. This deformation creates gaps, allowing fire and smoke to spread and intensify the fire. Utility Model Content

However, in the event of a large fire, the door body of the double-layered steel plate staggered splicing fire door is prone to deformation due to high temperatures. When deformation occurs, gaps will appear in the double-layered steel plate staggered splicing fire door, allowing fire and smoke to spread through the gaps and thus exacerbating the fire. This utility model proposes a double-layered steel plate staggered splicing fire door.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a double-layer steel plate staggered splicing fire door. (Refer to...) Figures 1-4A double-layer steel plate staggered splicing fire door includes a wall 1. The inner wall of the wall 1 is movably connected to a first fire door 10 and a second fire door 12. Fireproof glass 3 is fixedly installed on the inner wall of both the first fire door 10 and the second fire door 12. A water pump 6 is provided on one side of the wall 1. Two temperature sensors 5 are provided on both sides of the first fire door 10 and the second fire door 12. The water pump 6 works in conjunction with the temperature sensors 5. A cooling mechanism 2 is provided on one side of the wall 1.

[0024] The cooling mechanism 2 includes two water storage shells 204, which are fixedly installed on both sides of the wall 1. A diversion pipe 203 is fixedly connected between the tops of the two water storage shells 204. There are several diversion pipes 203. Several spray heads 205 are fixedly connected to the opposite sides of the two water storage shells 204. A conveying pipe 201 is fixedly connected to the bottom of one of the water storage shells 204. There are two conveying pipes 201. The surface of the conveying pipe 201 is fixedly connected to one side of the wall 1. Spray heads 202 are fixedly connected to the opposite sides of the two conveying pipes 201. There are several spray heads 202. A three-way pipe 206 is fixedly connected between the sides of the two water storage shells 204.

[0025] Reference Figure 1 and Figure 2 The outlet end of the water pump 6 is fixedly connected to the connecting pipe 8. One end of the connecting pipe 8 is fixedly connected to one end of the three-way pipe 206. By setting the connecting pipe 8, the water pumped by the water pump 6 can be conveniently transported under the action of the connecting pipe 8, so that the water can enter the three-way pipe 206.

[0026] Reference Figure 4 The bottom of the water pump 6 is provided with an installation plate 7, and the top of the installation plate 7 is fixedly connected to a support plate 14. There are two support plates 14. The top of the support plate 14 is fixedly connected to the bottom of the water pump 6. By reasonably setting the cooperation between the installation plate 7 and the support plate 14, the stability and firmness of the water pump 6 during use can be significantly improved, effectively preventing the water pump 6 from shifting during use, thereby ensuring that the normal operation of the water pump 6 is not affected.

[0027] Reference Figure 1 and Figure 2Two connecting plates 4 are fixedly connected to both sides of the first fire door 10 and the second fire door 12. One side of the connecting plate 4 is fixedly connected to one side of the temperature sensor 5. By setting the connecting plate 4, the user can easily fix the temperature sensor 5, increasing the stability and firmness of the temperature sensor 5 during use. By installing the temperature sensor 5, temperature changes can be easily monitored. When the temperature is too high, it can effectively prevent the first fire door 10 and the second fire door 12 from deforming. The temperature sensor 5 can be used to accurately control the water pump 6, ensuring that the water pump 6 starts in time and delivers cooling water, thereby effectively cooling the first fire door 10 and the second fire door 12.

[0028] Reference Figure 1 A high-temperature resistant sealing plate 11 is fixedly connected to one side of the second fire door 12. One side of the high-temperature resistant sealing plate 11 contacts one side of the first fire door 10. By installing the high-temperature resistant sealing plate 11 made of fluororubber, the sealing performance between the first fire door 10 and the second fire door 12 can be effectively improved, preventing fire and smoke from spreading through the gap between them.

[0029] Reference Figure 4 The water pump 6 has a fixed water inlet pipe 13 connected to its inlet end. The water inlet pipe 13 is connected to an external water pipe. By connecting the water pump 6 to the external water pipe through the water inlet pipe 13, the cooling water source can be conveniently accessed, so that the water pump 6 can effectively deliver the cooling water source.

[0030] Reference Figure 1 Two fireproof hinges 9 are fixedly connected to the opposite side of the first fire door 10 and the second fire door 12. The connection between the first fire door 10 and the second fire door 12 and the wall 1 is rotatably connected by the fireproof hinges 9. By setting the fireproof hinges 9, the effects of high temperature on the first fire door 10 and the second fire door 12 can be effectively prevented, thereby ensuring that the first fire door 10 and the second fire door 12 can be opened normally.

[0031] Working Principle: To prevent the first fire door 10 and the second fire door 12 from deforming due to high temperatures during a fire, the water pump 6 is first connected to the cooling water source through the inlet pipe 13. When a fire occurs, the temperature sensor 5 monitors the ambient temperature. Once the temperature rises, it works in conjunction with the microcontroller. The microcontroller receives the signal from the temperature sensor and compares it with a preset temperature threshold. When the temperature exceeds the preset value, the controller controls the water pump 6 to start, causing it to deliver cooling water through the inlet pipe 13. The water source is then transported through the connecting pipe 8 and enters the water storage tank 204 through the three-way pipe 206. Water is diverted through the diversion pipe 203 to improve the utilization efficiency of the water storage tank 204. Subsequently, the water flows to the sprinkler head 205, the delivery pipe 201 and the spray head 202, forming water droplets and water mist to cool the first fire door 10 and the second fire door 12, preventing them from deforming at high temperatures, thereby preventing the fire from spreading through the gaps in the deformed fire doors. It should be noted that the temperature sensor 5 and the microcontroller used in this utility model are DL17-GOF-GST9713 and STM32, respectively, which are mature and publicly available technologies. Their specific working principles need not be elaborated here.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
