[0042] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0043] The following combination Figures 1 to 4 , describing the embodiments of the present utility model.

[0044] According to an embodiment of the present invention, a container fire test device is provided, comprising:

[0045] Container body 1;

[0046] The fire generating unit 2 is provided inside the container body 1, and a fire source is suitable for being placed on the fire generating unit 2;

[0047] The temperature detection unit is movably arranged inside the container body 1 , and is suitable for detecting the temperature at different positions inside the container body 1 .

[0048] It should be noted that this embodiment uses a 40-foot container as the container body 1. Its external dimensions are 12.192 meters long, 2.438 meters wide, and 2.591 meters high. Its internal volume is approximately 11.8 meters x 2.13 meters x 2.18 meters, for a volume of approximately 67.5 cubic meters. In other embodiments, international standard containers of other sizes, such as 20-foot containers, may also be used. The actual size of the container body 1 is not limited here; a container of an appropriate size may be selected based on actual experimental needs.

[0049] It should be noted that in this embodiment, a metal storage tray is selected as the fire generating unit 2. Steel is preferred; in other embodiments, the fire generating unit 2 may be made of other materials. In this embodiment, the storage tray has specific dimensions of 0.8 m (inner length) x 0.8 m (inner width) x 0.2 m (inner height) to accommodate the 40-foot container used in this embodiment. In other embodiments, storage trays of other sizes or shapes may be selected as the fire generating unit 2. The specific configuration of the fire generating unit 2 is not limited herein.

[0050] Specifically, flammable materials can be placed on the fire generating unit 2 as a fire source. Common flammable materials include various combustible fiber products such as paper, wood, and cloth. These materials are easily ignited and burn rapidly under certain conditions, simulating the potential fire ignition of goods such as daily necessities within a container. Flammable liquids such as gasoline and alcohol are also highly volatile and will burn violently and rapidly upon contact with a fire source. This is useful for studying scenarios where flammable liquid leaks can cause fires.

[0051] The container fire experimental device provided by the present invention is based on the container body 1, creating a close-to-reality scene for the experiment. The internally arranged fire generating unit 2 is located inside the container body 1. By placing the fire source and controlling its type, intensity and other parameters, it can accurately simulate the source of the fire in the container, providing the possibility for studying the development of fire under different circumstances. The movable temperature detection unit can be flexibly placed in different positions inside the container body 1 to effectively detect temperature changes in various places. It provides a real and reliable simulation environment for studying the occurrence mechanism and spread law of fire in the container. It can not only help to deeply analyze the impact of fire on goods, personnel and the environment, but also provide a practical platform for testing the effects of various fire extinguishing technologies and formulating fire extinguishing and rescue strategies.

[0052] Furthermore, a mass collection unit 8 is provided at the bottom of the container body 1 to detect changes in mass when a fire occurs inside the container body 1. Specifically, the mass collection unit 8 is provided at the four corners of the container body 1 and is preferably a mass sensor to ensure the stability of the collected data.

[0053] Furthermore, it also includes a first moving component, which is arranged on the lower side of the fire generating unit 2 and is suitable for driving the fire generating unit 2 to move horizontally inside the container body 1.

[0054] As will be readily understood, the provision of a first mobile assembly enables the fire generating unit 2 to move horizontally within the container, enhancing the flexibility and operability of the experiment. This added mobility allows simulation of fires originating from various locations within the container, more realistically reflecting various fire scenarios that may arise during actual transportation. For example, it is possible to study differences in fire development trends, impact on the surrounding environment, and temperature distribution when the fire source is located near different locations such as the container door, sidewall, or corner.

[0055] Furthermore, the first moving component includes:

[0056] The first chute 31 is provided on the inner bottom surface of the container body 1 and is provided parallel to the length direction of the container body 1;

[0057] The second chute 32 is slidably disposed in the first chute 31 , and the second chute 32 is disposed perpendicular to the length direction of the container body 1 , and the fire generating unit 2 is slidably disposed in the second chute 32 .

[0058] As can be easily understood, by providing mutually perpendicular first and second chutes 31, 32 on the inner bottom surface of the container body 1 and sliding the fire generating unit 2 within the second chutes 32, the fire generating unit 2 can be flexibly moved within the two-dimensional plane of the container interior. This allows for more accurate simulation of fires originating at various locations within the container, encompassing areas from the long side to the wide side, thus increasing the diversity of fire location options in experimental scenarios.

[0059] In an alternative embodiment, a track-type mobile platform can be used as the first mobile component. Specifically, two parallel tracks are laid on the bottom of the container body 1, with the tracks aligning with the length and width of the container. The fire generating unit 2 is mounted on a platform that moves on the tracks. The platform is driven by motor-driven rollers to enable the fire generating unit 2 to move within the container body 1.

[0060] Furthermore, it also includes a drive assembly provided on the lower side of the fire generating unit 2, which can be a stepper motor and screw assembly or a hydraulic drive device. The stepper motor and screw assembly converts rotational motion into linear motion through the screw, which can accurately control the movement distance and speed of the fire generating unit 2 and accurately simulate the subtle differences in fire sources starting at different locations. The hydraulic drive device, although its system is relatively complex, has a large thrust and is suitable for situations where the fire generating unit 2 is large, requires a large driving force and the speed control requirements are not particularly strict. In actual selection, the most suitable drive assembly should be determined based on specific requirements, cost budget, and emphasis on accuracy, load capacity, etc. The specific setting form of the drive assembly is not restricted here.

[0061] Furthermore, it also includes a second movable component, which is arranged on the inner surface and / or inner top surface of the container body 1, and a temperature detection unit is arranged on the second movable component. The second movable component is suitable for driving the temperature detection unit to move on the inner surface and / or inner top surface.

[0062] As can be easily understood, the second mobile assembly is located on the inner surface or inner top surface of the container body 1 and drives the temperature detection unit to move. This allows the temperature detection unit to flexibly reach every corner of the container interior, comprehensively monitoring temperature changes at different locations during a fire, accurately capturing temperature distribution dynamics, and providing rich and accurate data for in-depth research on fire development patterns and heat transfer characteristics.

[0063] Furthermore, the second moving component includes:

[0064] The side movable groove 41 is provided on the inner surface of any container body 1, and the side movable groove 41 is provided parallel to the height direction of the container body 1;

[0065] The side moving part 42 is slidably set in the side moving groove 41. The side moving part 42 can slide and rise and fall along the height direction of the container body 1. A plurality of card slots 43 are arranged at intervals on the side moving part 42. The card slots 43 are suitable for carding the temperature detection unit. The card slots are preferably semicircular, which ensures that the card connection is firm while facilitating disassembly and assembly. They can be arranged at equal intervals or flexibly according to needs.

[0066] Furthermore, the second moving component further includes:

[0067] The top surface moving groove 44 is provided on the inner top surface of the container body 1 , and the top surface moving groove 44 is provided parallel to the width direction of the container body 1 ;

[0068] The top surface moving part 45 is slidably set in the top surface moving groove 44. The top surface moving part 45 can slide along the width direction of the container body 1. A plurality of card slots 43 are arranged at intervals on the top surface moving part 45. The card slots 43 are suitable for carding the temperature detection unit. The card slots are preferably semicircular, which ensures that the card connection is firm while facilitating disassembly and assembly. They can be arranged at equal intervals or flexibly according to needs.

[0069] Furthermore, the temperature detection unit includes:

[0070] A plurality of thermocouple thermometers are provided, and the thermocouple thermometers are suitable for collecting temperature changes in the container body 1 during the test process.

[0071] It should be noted that thermocouple thermometers offer the advantages of a wide temperature measurement range, fast response, high measurement accuracy, and excellent stability. They can adapt to the various temperatures encountered in container fire experiments, promptly capturing temperature changes and accurately reflecting temperature differences at different locations within the container, thereby ensuring accurate and consistent experimental data. In other embodiments, other temperature measurement devices with temperature measurement capabilities, such as resistance thermometers, may also be used as the temperature detection unit.

[0072] Furthermore, the temperature detection unit further includes a radiation heat flux meter, which is suitable for collecting heat radiation flux data in the container body 1 during the experiment.

[0073] As can be easily understood, the radiation heat flux meter is used to collect thermal radiation flux data within the container body 1 during the experiment. This helps researchers understand the propagation patterns and intensity distribution of heat radiation during a fire. This data enables a more comprehensive analysis of the fire's development, including its spread direction and speed, as well as the extent of its thermal radiation impact on the surrounding environment and cargo.

[0074] Furthermore, a fire extinguishing unit 5 is included. The fire extinguishing unit 5 is arranged on the top of the container body 1 and is suitable for spraying a fire extinguishing medium into the interior of the container body 1 .

[0075] Specifically, the top of the container is provided with a fire extinguishing hole 51 extending through the top surface of the container, and the fire extinguishing hole 51 is located at the center of the top surface of the container body 1. This placement of the fire extinguishing hole 51 at the center of the top surface of the container body 1 facilitates even coverage of fire extinguishing materials across the interior of the container. In the event of a fire, the fire extinguishing material can more comprehensively reach the fire source and surrounding areas, improving the fire extinguishing effect.

[0076] Specifically, the fire extinguishing unit 5 includes a sliding block 52, an adjustable universal ball 53, and a fire extinguishing nozzle 54. The sliding block 52 is slidably mounted on the top movable member 45 and can slide on the top movable member along the length of the container body 1. The adjustable universal ball 53 is rotatably mounted on the sliding block 52 and is connected to an external fire extinguishing mechanism via a pipeline, which is suitable for transporting fire extinguishing material from the external fire extinguishing mechanism to the adjustable universal ball 53. The fire extinguishing nozzle 54 is connected to the adjustable universal ball 53 and is suitable for spraying the fire extinguishing material in the pipeline into the interior of the container body 1 by rotating the adjustable universal ball 53.

[0077] Specifically, the sliding block 52 can slide on the top movable member along the length of the container body 1, and the top movable member can slide along the width of the container body 1, allowing the fire sprinkler 54 to be horizontally adjusted on the inner top surface of the container body 1. This allows the fire extinguishing material to be precisely positioned and sprayed according to the specific location of the fire, thereby enhancing the targeted and flexible nature of fire extinguishing. The adjustable universal ball 53 is capable of rotating and driving the fire sprinkler 54 to spray at multiple angles. Regardless of the location of the fire source, the direction of the fire, or the complexity of the placement of the cargo inside the container, the fire sprinkler 54 can be adjusted to the optimal spray angle by adjusting the universal ball 53, ensuring that the fire extinguishing material can accurately reach the fire source, maximizing the fire extinguishing effect and minimizing damage to the cargo and container structure within the container.

[0078] In an optional embodiment, multiple rotatable fire-extinguishing nozzles can be installed on the top of the container as the fire-extinguishing unit 5. The fire-extinguishing nozzles can be moved via tracks fixed to the top. The tracks are arranged along the length and width of the container, and the nozzles are driven and rotated on the tracks by a motor. Each nozzle is connected to an external fire-extinguishing mechanism via an independent pipeline. However, this solution may be relatively complex and costly, requiring more sophisticated equipment maintenance and management. The specific configuration of the fire-extinguishing unit 5 is not limited here, and it is sufficient to ensure safe and stable fire extinguishing after the container fire test.

[0079] Furthermore, an observation window 6 is provided on the container body 1, and a camera is provided outside the observation window 6;

[0080] It should be noted that the camera can be set as a high-speed camera and an infrared camera to capture videos and infrared images of fire experiments, providing support for fire research and analysis.

[0081] Furthermore, a smoke hole 7 is opened on the top of the container body 1, and the smoke hole 7 is connected to the smoke analyzer.

[0082] It should be noted that the addition of a flue gas analyzer can monitor the changes in flue gas composition and concentration in real time to provide a basis for judging the fire development stage and combustion characteristics, ensure personnel safety, assist in the formulation of fire extinguishing strategies, help analyze the impact of fire on cargo and structures, and improve the scientificity and effectiveness of fire response.
