Description

Technical Field

[0001] This utility model relates to the field of fire safety education equipment technology, and in particular to a demonstration device for simulating the spread of smoke in a residential building fire. Background Technology

[0002] In residential building fires, smoke spread is one of the main factors leading to casualties. Currently, public education on smoke spread in fire scenes mainly relies on videos and written explanations. However, these methods lack intuitiveness, making it difficult for the public to quickly and clearly understand the actual flow of smoke within residential buildings. This, in turn, affects their grasp of basic fire escape knowledge, especially the learning of how to avoid smoke-related injuries. Therefore, there is an urgent need for a device that can visually demonstrate the smoke spread process in residential building fires to improve the effectiveness of public education. Utility Model Content

[0003] In view of this, the present invention aims to provide a demonstration device for simulating the spread of smoke in a residential building fire, so as to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0004] The technical solution of this utility model embodiment is implemented as follows:

[0005] A demonstration device for simulating the spread of smoke in a residential building fire includes a transparent box and a multi-story structure set inside the transparent box. The transparent box is a multi-story cuboid structure made of fully transparent acrylic sheet.

[0006] The floor structure includes an enclosed stairwell located in the middle of each floor and simulated rooms symmetrically arranged on both sides of the stairwell. The stairwell is equipped with stairs connecting each floor, and the front of the stairwell is hinged with an openable fire door.

[0007] Each of the simulated rooms has a door hinged to the side near the stairwell, windows hinged to the outer wall of the simulated room, and a tray for placing smoke pellets inside the simulated room;

[0008] A smoke exhaust pipe is installed throughout the stairwell, and the smoke exhaust pipe extends to the outside of the transparent enclosure.

[0009] Preferably, the door is completely transparent for easy observation.

[0010] Preferably, the door and window are hinged to the transparent box wall, and a gap is reserved between the door and window and the door frame.

[0011] Preferably, the tray has a detachable structure.

[0012] Preferably, the fire door is provided with a sealing strip on its edge to reduce smoke leakage during the demonstration.

[0013] Preferably, the staircase is made of transparent acrylic material, and the height and width of the steps are simulated to the actual residential staircase at a 1:10 scale. The staircase has a detachable structure.

[0014] The present invention has the following advantages due to the adoption of the above technical solution:

[0015] 1. Visual Display: The box, made of fully transparent acrylic panels, allows the public to observe the flow of smoke within the residential building from all 360 degrees without any blind spots. Compared to videos and text, it is more intuitive and three-dimensional, enhancing the effectiveness of science education.

[0016] Second, it is highly interactive: the fire source can be started and the ventilation and smoke exhaust system can be operated manually through the control panel, realizing dynamic demonstration, increasing the public's sense of participation and attention, and making it easier for operators to adjust the demonstration content and pace according to different audiences.

[0017] Third, it simulates various scenarios, such as room fires, pipe shaft fires, and elevator fires. It covers common fire hazard locations in residential buildings, comprehensively demonstrates the spread path and characteristics of smoke under different conditions, and helps the public master diverse escape knowledge.

[0018] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] like Figure 1-4 The present invention provides a demonstration device for simulating the spread of smoke in a residential building fire, including a transparent box 1 and a floor structure 10 set inside the transparent box 1. The transparent box 1 is a multi-layer cuboid structure and is made of fully transparent acrylic sheet.

[0030] The floor structure 10 includes an enclosed stairwell 2 located in the middle of each floor and simulated rooms 3 symmetrically arranged on both sides of the stairwell 2. The stairwell 2 is equipped with staircases 4 connecting each floor, and the front of the stairwell 2 is hinged with an openable fire door 5.

[0031] Each simulated room 3 has a door 6 hinged to the side near the stairwell 2, and windows 7 hinged to the outer wall of the simulated room 3. The interior of the simulated room 3 is equipped with a tray 8 for placing smoke pellets.

[0032] A smoke exhaust pipe 9 is installed throughout the stairwell 2, and the smoke exhaust pipe 9 extends to the outside of the transparent enclosure 1.

[0033] In this embodiment, the door 6 is completely transparent for easy observation. The door 6, window 7 and the wall of the transparent box 1 are hinged together. A gap is reserved between the door 6, window 7 and the door frame. The tray 8 is a detachable structure.

[0034] In this embodiment, the fire door 5 is provided with a sealing strip on its edge to reduce smoke leakage during the demonstration. The staircase 4 is made of transparent acrylic material. The height and width of the steps of the staircase 4 are simulated at a 1:10 scale to simulate the actual residential staircase. The staircase 4 has a detachable structure.

[0035] When this utility model is in operation:

[0036] Preparation: The staff opens the window 7 on the outside of the transparent box 1, places the smoke pellets on the tray 8 in the room 3, and closes the window 7.

[0037] Simulated Fire Room Door Opening: Open door 6 of the target simulated room 3. The window 7 of this room can be opened or closed as needed for the demonstration. Ignite the smoke pellets on tray 8 to produce simulated smoke. At this point, the audience can observe the smoke rising due to the heat, first filling the top of room 3, and then spreading towards the stairwell through the opened door 6. Next, staff can choose to close or open the fire door 5 of stairwell 2: if fire door 5 is closed, the audience can see smoke gradually gathering in the corridor and spreading upwards along stair 4.

[0038] Smoke exhaust system demonstration: Staff can open the electric valve on the smoke exhaust pipe 9 through the control panel and start the fan at the same time. The audience can see the smoke being discharged from the transparent box 1 through the smoke exhaust pipe 9 and intuitively feel the role of the smoke exhaust system in controlling the spread of smoke.

[0039] Special demonstration of external wind force: During the simulation, staff can also apply wind force from the outside through window 7 using small fans or other equipment. When a fire breaks out in the simulated room, the external wind force will change the speed and direction of smoke spreading from the room to the corridor; when a fire breaks out in the simulated stairwell, the external wind force will affect the flow of smoke in the stairwell, allowing the audience to understand the impact of external wind force on the spread of fire smoke.

[0040] Assisted observation and explanation: During the demonstration, staff can explain to the audience the correct escape routes and methods in different fire scenarios based on the direction of the smoke, helping the audience to better understand and master the relevant knowledge.

[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
