Description
Technical Field
[0001] This utility model relates to the field of fire door technology, specifically a fire door fire resistance performance simulation testing device. Background Technology
[0002] Fire doors are doors with fire-resistant functions, generally classified as Class A, Class B, and Class C. They are often filled with non-combustible materials such as cement mortar and perlite wool, which can isolate the fire source and block the spread of flames and smoke during a fire. Fire resistance testing is essential. In the event of a fire, qualified fire doors can buy time for people to escape, ensuring their safety, while also preventing the spread of fire and reducing property damage. Furthermore, many countries' building codes and regulations require the use of fire doors in specific buildings; fire resistance testing is crucial to ensuring compliance and is a necessary part of building review and acceptance. In addition, fire doors must maintain structural integrity during a fire; fire resistance testing verifies whether they meet this requirement and also helps ensure the quality of fire door products, facilitating the selection of reliable fire door products by the construction industry and users.
[0003] Existing fire doors suffer from several problems during fire resistance performance simulation testing. First, inadequate protective measures make it difficult to confine fire door combustion to a specific space, allowing flames and smoke to easily spread to the work area, polluting the environment and lacking effective smoke guidance and purification methods, threatening the health of operators. Second, fire extinguishing operations are inconvenient and unsafe; the lack of a convenient fire extinguishing system makes it difficult to extinguish the fire promptly after the test or when combustion becomes uncontrolled, easily leading to safety accidents. Third, improper handling of liquid plastics and solid particulate impurities generated by fire door combustion allows these impurities to easily enter the device, contaminating components, reducing water recycling efficiency, and affecting the device's operation and lifespan. Fourth, it hinders operators from observing the tested state of the fire door, making it difficult to accurately assess whether combustion is under control and preventing timely intervention, increasing safety hazards during testing.

[0042] In actual operation, when this device is used and the fire resistance performance of the fire door needs to be checked, the staff first places the fire door in the top of the placement slot 1104, then pours the accelerant into the placement slot 1104 and ignites it. After that, the frame 2101 is closed, and the fixing screw sleeve 2403, fixing bracket 2401, and bolt 2402 are installed to fix the frame 2101. Then the staff can observe the fire door undergoing the flame combustion process through the observation window 2102 until the accelerant in the placement slot 1104 is burned out, or the fire inside the device is out of control. At this time, the staff can start the liquid pump 1201 to draw water from the liquid tank 3 and spray it out through the spray head 1303 to directly extinguish the fire on the door. At the same time, the air inlets on both sides of the combustion box 1101 can be blocked to prevent the entry of external air. The two work together to extinguish and cool the door inside the device.
