Description

Technical Field

[0001] This utility model belongs to the field of civil defense door technology, and more specifically, it relates to a fireproof civil defense door. Background Technology

[0002] Civil defense doors are the doors at the entrances and exits of civil defense projects. Civil defense doors are classified in a relatively clear manner, including ordinary single and double-leaf protective airtight doors and airtight doors, as well as single and double-leaf protective airtight doors and airtight doors with movable thresholds, and other types of civil defense equipment.

[0003] Based on the above, the inventors have discovered the following problems: Current air-raid shelter doors are usually quite large and require considerable force to open. In the event of a fire, the difficulty of opening the door will further increase due to high temperatures, smoke, or panic among personnel, which may even affect evacuation efficiency and personnel safety.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide a fireproof and personnel protection door, in order to achieve a more practical value. Utility Model Content

[0027] Example:

[0028] As attached Figure 1 To be continued Figure 5 As shown:

[0029] This utility model provides a fireproof civil defense door, including a door frame 1 and a set of civil defense door bodies 2 hinged in the middle of the door frame 1. A door lock disc 3 is movably connected to the front of the civil defense door body 2. A spline groove 4 is opened inside the door lock disc 3. A fixing frame 5 is installed on one side of the civil defense door body 2. A motor 6 is installed on one side of the fixing frame 5. A connecting spline 7 is fixedly connected to the output end of the motor 6. The size of the spline groove 4 matches that of the connecting spline 7. An installation block 8 is installed on one side of the civil defense door body 2. A universal wheel 9 is installed at the bottom of the installation block 8. The universal wheel 9 is in contact with the ground.

[0030] By using the door lock disc 3, spline groove 4, fixing bracket 5, motor 6, and connecting spline 7 in conjunction, when the intelligent control system 14 detects an emergency such as opening the door or a fire, the system automatically issues a command to start the motor 6. The output end of the motor 6 drives the connecting spline 7 to rotate. Since the connecting spline 7 is inserted into the spline groove 4 of the door lock disc 3, it can drive the door lock disc 3 to rotate, realizing the automatic unlocking of the door lock. By holding the handle 13 and applying a certain pulling force, the air defense door body 2 rotates around the door frame 1 under the action of the hinge device. At the same time, the universal wheel 9 rolls on the ground to assist the air defense door to open smoothly. Through the above design, the reaction speed and operation efficiency in emergency situations can be improved, while ensuring the smooth opening and closing of the air defense door body 2. This not only enhances the functionality of the air defense door body 2, but also improves safety and reliability through automated operation, making the design more adaptable to the needs of modern emergency protection.

[0031] The air defense door body 2 includes an outer layer 10, a middle layer 11, and an inner layer 12. The outer layer 10 is an explosion-proof layer, the middle layer 11 is a fireproof layer, and the inner layer 12 is a sealed layer.

[0032] Through the combined use of the outer layer 10, the middle layer 11, and the inner layer 12, this structure provides multiple layers of protection, capable of simultaneously addressing threats from explosions, fires, and toxic gases. Each layer of material has a specific function, providing effective protection in various disaster scenarios and ensuring the safety of personnel.

[0033] The explosion-proof layer is a glass fiber reinforced polyester composite material with a thickness of 50-80mm.

[0034] This material possesses excellent explosion-proof properties. Within its thickness range, it can effectively withstand blast shock waves of a certain intensity, preventing debris from damaging the interior of the air-raid shelter door. Glass fiber reinforced polyester composite material, through a special molding process, ensures uniform fiber distribution within its structure, forming a high-strength structural network, thereby improving its overall impact resistance.

[0035] The fireproof layer is a composite material of aluminum silicate fiber and aerogel.

[0036] Aluminosilicate fibers possess excellent high-temperature resistance, maintaining structural stability even at high temperatures and effectively preventing the transfer of flames and heat. Aerogel, a novel nanoporous material, has an extremely low thermal conductivity, further enhancing the heat insulation effect of the fireproof layer. The combination of aluminosilicate fibers and aerogel forms a highly efficient fireproof and heat-insulating structure, buying valuable time for personnel evacuation and equipment protection in the event of a fire.

[0037] The sealing layer adopts a magnetic structure and an SMA-driven sealing strip.

[0038] The inner layer 12 combines a magnetic structure with an SMA (shape memory alloy) driven sealing strip, providing superior sealing performance. The magnetic structure ensures that the air-raid shelter door fits tightly against the door frame 1 when closed, forming an initial seal. The SMA driven sealing strip can automatically adjust its shape according to temperature changes, filling gaps in the door and ensuring a high degree of sealing to prevent smoke, toxic gases, and other contaminants from entering the air-raid shelter.

[0039] Once the air-raid shelter door is fully closed, the magnetic structure and SMA-driven sealing strip come into play, achieving a reliable seal and preventing smoke and flames from entering the air-raid shelter, thus providing a safe refuge for personnel.

[0040] The surface of the air-raid shelter body 2 is coated with a self-healing coating containing microcapsule flame retardant.

[0041] When exposed to flames or high temperatures, the microcapsule flame retardant in this coating releases flame-retardant gases, inhibiting the spread of flames and thus providing flame retardancy. Simultaneously, when tiny cracks or damage appear on the coating surface, the repair agent within the microcapsules automatically flows out, filling the cracks and undergoing a chemical reaction to achieve self-repair, thereby extending the service life of the air-raid shelter and improving the stability of its protective performance.

[0042] The handle 13 is fixedly connected to the left side of the front of the air defense door body 2.

[0043] An intelligent control system 14 is installed on one side of the door frame 1.

[0044] The intelligent control system 14, as the core control unit of the entire process, receives signals from temperature sensors, smoke detectors, and pressure sensors. It analyzes and processes these signals, and determines whether the current environment is in a dangerous state or whether corresponding measures need to be taken based on preset logic and thresholds. The temperature sensor is responsible for monitoring temperature changes in the environment in real time, converting the sensed temperature information into electrical signals to provide basic data for subsequent judgment and processing. Following the temperature sensor, the smoke detector is used to detect whether there is smoke in the environment. When smoke is generated, the smoke detector converts it into a corresponding electrical signal. This signal, together with the signal from the temperature sensor, serves as the basis for the system to judge the environmental state. After the intelligent control system 14 makes a judgment, if communication with the outside is required, the wireless communication module comes into play. It can send out the judgment results and status information of the system in the form of wireless signals to realize communication with the remote monitoring center or other devices, facilitating remote monitoring and management. To ensure that the system can still work normally in an emergency, the emergency power supply provides backup power support for the entire system. When the main power supply fails or is interrupted, the emergency power supply can provide power in time to ensure the continuous operation of the system.

[0045] The specific usage and function of this embodiment are as follows:

[0046] Before using this utility model, first confirm the integrity of the device. When the intelligent control system 14 detects an emergency such as opening the door or a fire, the system automatically issues a command to start the motor 6. The output end of the motor 6 drives the connecting spline 7 to rotate. Since the connecting spline 7 is inserted into the spline groove 4 of the door lock disc 3, it can drive the door lock disc 3 to rotate, realizing the automatic unlocking of the door lock. Hold the handle 13 and apply a certain pulling force. The body of the air defense door 2 rotates around the door frame 1 under the action of the hinge device. At the same time, the universal wheel 9 rolls on the ground to assist the air defense door to open smoothly. The above design can improve the reaction speed and operation efficiency in emergency situations, while ensuring the smooth opening and closing of the air defense door body 2. It not only enhances the functionality of the air defense door body 2, but also improves safety and reliability through automated operation, making the design more adaptable to the needs of modern emergency protection. Through the combined use of the outer layer 10 (explosion-proof layer), the middle layer 11 (fireproof layer) and the inner layer 12 (sealing layer), this structure provides multiple protections and can simultaneously deal with the threats of explosion, fire and toxic gas. Each layer of material has a specific function, providing effective protection and ensuring the safety of personnel in different disaster situations.
