Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment detection, in particular to an ignition fuel forming die for a fire test experiment. Background Art

[0002] Conventional fire test experiments usually require the production of fuel sources according to the test scenario, such as paper fuel sources. The shape of the paper fuel source required for each experiment requires the paper fuel to be filled into a specific cylindrical refractory container, and then the paper fuel is manually compacted to reach a certain height. Finally, a circular hole is passed through the middle of the compacted paper fuel from top to bottom for ventilation. The above operations are relatively cumbersome and affect the efficiency of the test experiment. On the other hand, since there are no relevant tools to compact the paper fuel, the shape of the paper fuel produced each time is not uniform, and the size and height of the through hole in the middle are also different, resulting in large differences in parameters such as the smoldering time, flame breakthrough time, and smoke concentration during the combustion of the paper fuel in different experiments, which in turn affects the controllability, accuracy, and effectiveness of the fire test experiment. Utility Model Content

[0003] In view of this, the purpose of the utility model is to provide an ignition fuel forming die for a fire test experiment, so as to simplify the production of the fuel source shape and make the shape of the fuel source more standardized, thereby improving the experimental efficiency and accuracy.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A fire test experiment ignition fuel forming mold includes a chassis, a cylindrical tube vertically set up on the chassis for placing fuel, a cylindrical rod vertically set up at the axis of the cylindrical tube, a compaction plate assembly that can move up and down along the axis of the cylindrical rod is arranged outside the cylindrical rod, and a compaction space for placing ignition fuel is formed between the bottom of the compaction plate assembly and the chassis.

[0006] The compacting plate assembly comprises a pushing rod with a hollow middle portion for sleeved outside the cylindrical rod, a pressing plate is arranged below the pushing rod, and the pressing plate is in the shape of a disc and can move up and down along the axial direction of the cylindrical barrel.

[0007] The outer wall of the cylindrical rod is provided with scale marks from the bottom plate upwards for measuring the height of the ignition fuel.

[0008] The chassis is an annular net-shaped structure, and a bottom hole for installing a cylindrical rod is opened in the middle of the chassis.

[0009] A through groove is provided on the plate surface of the pressure plate.

[0010] Support feet for preventing tipping are evenly arranged around the outer wall of the cylindrical tube.

[0011] The cylindrical tube is made of refractory material.

[0012] The pushing rod is made of light-transmitting material.

[0013] The beneficial effects of the utility model are:

[0014] 1. After the cylindrical rod is installed in the cylindrical tube, the fuel source is placed in the cylindrical tube according to the usage amount. The compaction plate assembly is manually operated, and the compaction plate compacts the fuel source downward along the cylindrical rod. The push rod is set on the compaction plate to facilitate pushing and removing the compaction plate. The mold standardizes the process of making the fuel source required for the fire test experiment, simplifies the steps of making the fuel source, and improves the efficiency of making the fuel source.

[0015] 2. The cylindrical rod is vertically set in the middle of the cylinder, so that after the fuel source is compacted, a through hole is naturally formed in the middle of the fuel source. The hole is formed in a relatively standardized and neat manner, and the size can be controlled according to the diameter of the cylindrical rod, thereby making the air intake efficiency of the fuel source different to simulate the combustion effect of the degree of combustion under different scenarios, such as the effect of thick smoke under different combustion.

[0016] 3. The scale markings on the outer wall of the cylindrical rod can be identified through the push rod made of transparent material. Compared with the traditional manual visual method, it can more accurately control the compaction height of the fuel source, and then combine the mass of the placed fuel source to roughly calculate the combustion effect of the fuel source.

[0017] 4. The chassis with an annular mesh structure ensures the expansion space of the structure under long-term high temperature, making the overall structure more stable. On the other hand, it makes the chassis lightweight and facilitates the rapid arrangement of the test.

[0018] 5. The through grooves on the surface of the pressure plate facilitate the discharge of air in the compaction space when the pressure plate is pressed down, reducing the resistance during pressing and improving the operating efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the present invention are further described below in conjunction with the accompanying drawings and through specific implementation methods. It is understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for the convenience of description, only the parts related to the present invention are shown in the accompanying drawings, rather than all of them.

[0025] Reference Figure 1 The utility model proposes an ignition fuel forming mold for a fire test experiment, including a chassis 2, a cylindrical barrel 1 for placing fuel vertically set up on the chassis 2, a cylindrical rod 3 vertically set up at the axis of the cylindrical barrel 1, a compacting plate assembly 4 that can move up and down along the axis of the cylindrical rod 3 is arranged outside the cylindrical rod 3, and a compacting space 5 for placing the ignition fuel is formed between the compacting plate assembly 4 and the chassis 2 below.

[0026] Reference Figure 2 The compacting plate assembly 4 includes a push rod 41 with a hollow center for sleeved outside the cylindrical rod 3, and a pressure plate 40 is arranged below the push rod 41. The pressure plate 40 is disc-shaped and can move up and down along the axial direction of the cylindrical tube 1.

[0027] Furthermore, after the cylindrical rod 3 is installed in the cylindrical tube 1, the fuel source is placed in the cylindrical tube 1 according to the usage amount, the compacting plate assembly 4 is manually operated, and the compacting plate 40 compacts the fuel source downward along the cylindrical rod 3. The pushing rod 41 is arranged on the compacting plate 40, which is convenient for pushing and removing the compacting plate 40. Before igniting the fuel source, the compacting plate assembly 4 and the cylindrical rod 3 are removed. The mold standardizes the process of making the fuel source required for the fire test experiment, simplifies the steps of making the fuel source, and improves the efficiency of making the fuel source.

[0028] The cylindrical rod 3 is vertically set in the middle of the cylindrical tube 1, so that after the fuel source is compacted, a through hole is naturally formed in the middle of the fuel source. The hole is formed in a relatively standardized and neat manner, and the size can be controlled according to the diameter of the cylindrical rod 3, thereby making the air intake efficiency of the fuel source different to simulate the combustion effect of the degree of combustion under different scenes, such as the effect of thick smoke under different combustion.

[0029] Reference Figure 3 The outer wall of the cylindrical rod 3 is provided with a scale mark 30 for measuring the height of the ignition fuel from the bottom plate 2. The scale mark on the outer wall of the cylindrical rod 3 can be identified through the push rod 41 made of transparent material. Compared with the traditional manual visual method, the compaction height of the fuel source can be more accurately controlled, and then combined with the mass of the placed fuel source, the combustion effect of the fuel source can be roughly measured.

[0030] Reference Figure 4The chassis 2 is an annular mesh structure, and a bottom hole 20 for installing the cylindrical rod 3 is opened in the middle of the chassis 2. The chassis 2 with an annular mesh structure ensures the expansion space of the structure under high temperature for a long time, making the overall structure more stable. On the other hand, it makes the chassis lighter and convenient for the rapid arrangement of the test.

[0031] Reference Figure 2 or Figure 3 , a through groove 400 is provided on the disk surface of the pressure plate 40. The through groove provided on the disk surface of the pressure plate 40 facilitates the discharge of air in the compaction space 5 when the pressure plate 40 is pressed down, reduces the resistance during pressing down, and improves the operating efficiency.

[0032] Reference Figure 5 As a preferred embodiment, support feet 10 for preventing tipping are evenly arranged around the outer wall of the cylindrical tube 1. The support feet 10 around the cylindrical tube 1 wall prevent the cylindrical tube 1 from tipping over during the test, thereby ensuring the safety of the test.

[0033] Furthermore, the cylindrical tube 1 is made of refractory material, such as ceramic fiber, which has good thermal insulation and mechanical properties, and is also relatively lightweight, which facilitates the efficient arrangement of the scene; the pushing rod 41 is made of light-transmitting material, such as acrylic, which makes it convenient to observe the scale mark 30 on the cylindrical rod 3 when pushing the pressure plate.
