Description

Technical Field

[0001] The present invention belongs to the field of pyrotechnic simulation training facilities, and particularly relates to a combustion pool for a modular combustion chamber facilitating fuel simulation. Background Art

[0002] In the field of pyrotechnic characteristic training facilities, as a key device for simulating fuel combustion and conducting pyrotechnic characteristic research and training, the performance and function of the combustion pool for a modular combustion chamber play a crucial role in the training effect and research accuracy.

[0003] Currently, in terms of the structure of existing combustion pools, the cavity structures of most combustion pools are fixed, making it difficult to adapt to diverse simulation requirements. For example, when simulating different types of fire scenarios, such as fires in narrow spaces, open areas, and irregular spaces, the combustion pool with a fixed structure cannot flexibly change its shape, resulting in a large deviation between the simulation effect and the actual scenario, unable to provide a real and effective training environment for trainers, and also restricting the in-depth research on pyrotechnic characteristics under different fire scenarios. In addition, during fuel injection simulation, the mixing ratio of fuel and air often cannot be accurately controlled, leading to incomplete and unstable combustion, and it is difficult to accurately simulate the combustion phenomenon in a real fire.

[0004] By combining the above two problem entry points, we can find that when using existing devices on the market, it is very difficult to avoid the above-mentioned problems simultaneously. Moreover, even if these problems can be solved, external devices need to be connected, thus failing to achieve the desired effect. Therefore, we propose a combustion pool for a modular combustion chamber facilitating fuel simulation that can change the shape of the combustion pool according to training requirements during use, thereby simulating more types of fire scenarios, meeting diverse training needs, and providing richer experimental conditions for studying pyrotechnic characteristics under different space conditions. Summary of the Invention

When the turntable rotates, the connecting rod is used to pull the rack to move linearly, and the movement of the rack drives the gear meshed with it to rotate. The gear is sleeved on the movable pipe, thereby driving the movable pipe to rotate, realizing the adjustment of the angles of the spray heads, enabling the spray heads to accurately aim at the combustion area, improving the fire extinguishing effect, and enhancing the flexibility and adaptability of the fire extinguishing structure.

[0025] The present invention is further configured such that: a filtering structure is arranged inside the spray head, and the spray orifice of the spray head is fan-shaped.

Detailed implementation mode

[0039] The present invention will be further described in detail below with reference to the accompanying drawings.

[0040] Embodiment 1:

[0041] Refer to Figures 1-6 , a combustion pool for a modular combustion chamber facilitating fuel simulation, comprising a support 1, and a simulated combustion chamber structure 2 is arranged on the top of the support 1;

[0042] The simulated combustion chamber structure 2 includes two movable side plates 21. The front side and the rear side of the opposite sides of the two movable side plates 21 are respectively rotatably connected with movable side plates 22 through hinges. An adjustable side plate 23 is rotatably connected between the opposite sides of the two movable side plates 22. The movable side plates 21 and the adjustable side plate 23 are both slidably connected with the support 1. A fuel injection assembly 24 is bolted to the top of the support 1, and the fuel injection assembly 24 is used in cooperation with the adjustable side plate 23. By providing the simulated combustion chamber structure 2, through the hinge connection between the movable side plates 21, the movable side plates 22 and the adjustable side plate 23, the shape of the simulated combustion chamber structure 2 can be changed, which enables the combustion pool to flexibly adapt to the simulation of different types of fire scenarios, such as fires in narrow spaces, open areas and irregular spaces, greatly improving the fit between the simulation effect and the actual scenario, providing a more real and effective training environment for training personnel, and also being conducive to in-depth research on the smoke and fire characteristics under different fire scenarios. And through the fuel injection assembly 24, the mixing ratio of fuel and air can be accurately controlled, enabling the fuel to burn fully and stably, more accurately simulating the combustion phenomenon in a real fire, and improving the accuracy and reliability of the combustion simulation.

[0043] Such as Figure 3As shown, sliders 4 are bolted to the bottoms of the movable side plate 21 and the adjusting side plate 23, and the surfaces of the sliders 4 are in sliding contact with the inner wall of the support 1. Bidirectional lead screws 5 are rotatably connected to the front and rear sides of the bottom of the support 1, and the two sliders 4 on both sides are threadedly connected to the surfaces of the bidirectional lead screws 5. The sliding of the movable side plate 21 and the adjusting side plate 23 is realized through the cooperation of the sliders 4 and the bidirectional lead screws 5, so as to conveniently change the shape of the combustion chamber. The operation is simple and accurate, improving the adjustability and flexibility of the combustion chamber.

[0044] As Figure 1 and Figure 6 shown, a flexible sealing plate 6 is arranged between the sides of the two sliders 4 close to the inner wall of the support 1, and baffles 7 are arranged on the sides of the front and rear sliders 4 close to the inner wall of the support 1, and the surfaces of the baffles 7 are in sliding contact with the inner wall of the support 1. The sealing performance of the combustion chamber is enhanced through the arrangement of the flexible sealing plate 6 and the baffles 7, preventing fuel leakage and heat dissipation, improving the accuracy and safety of combustion simulation, and at the same time reducing the impact on the environment.

[0045] As Figure 4 shown, the fuel injection assembly 24 includes a housing 241, the housing 241 is bolted to the top of the support 1, a mixing chamber 242 is bolted inside the housing 241, a connecting pipe 243 communicates with the top of the mixing chamber 242, and the top of the connecting pipe 243 extends to the top of the housing 241. Bellows 244 communicate with the front and rear sides of the mixing chamber 242, and the side of the bellows 244 close to the adjusting side plate 23 is bolted to it. The tops of the bellows 244 and the connecting pipe 243 are both communicated with an injection pipe 245. An inlet part 246 communicates with the bottom of the mixing chamber 242, and the bottom of the inlet part 246 extends to the bottom of the support 1. Two flow guide plates 247 are bolted to the bottom inside the mixing chamber 242. By setting the fuel injection assembly 24, the fuel and air are pre-mixed through the inlet part 246, then enter the mixing chamber 242, and are fully mixed under the action of the flow guide plates 247, enabling the fuel to burn fully, improving the accuracy and stability of combustion simulation. The mixed gas enters the injection pipe 245 through the bellows 244 and the connecting pipe 243, and is finally injected into the combustion chamber for combustion simulation. At the same time, the bellows 244 can expand and contract with the movement of the adjusting side plate 23, ensuring that the fuel injection area can cover the inside of the combustion chamber.

[0046] As Figure 5As shown, the inlet member 246 includes a DC section 246a. The top of the DC section 246a is connected to a gradually expanding section 246b, and the gradually expanding section 246b is connected to the mixing chamber 242. A flow splitting ring 246c is sleeved on the surface of the DC section 246a, and the flow splitting ring 246c is externally connected to a gas fuel input device. A plurality of flow splitting pipes 246f are annularly connected to the inner wall of the flow splitting ring 246c, and the other ends of the flow splitting pipes 246f extend into the DC section 246a. A jet orifice plate 246d is bolted inside the flow splitting pipe 246f. A plurality of spoiler columns 246e are bolted in a ring shape at the top of the inner wall of the DC section 246a. By providing the inlet member 246, the gas fuel enters the flow splitting pipes 246f through the flow splitting ring 246c, is sprayed into the DC section 246a through the jet orifice plate 246d, and is mixed with the air entering from the bottom of the DC section 246a. Under the action of the spoiler columns 246e, the air flow is further disturbed, enabling the fuel and air to be fully mixed, allowing the fuel to be evenly mixed with the air, improving the mixing effect, thereby achieving more stable and sufficient combustion and enhancing the authenticity of the combustion simulation. The mixed gas then enters the mixing chamber 242 through the gradually expanding section 246b.

[0047] As Figure 4 shown, two flow guiding plates 247 are arranged in a stacked manner at the bottom inside the mixing chamber 242. The inner parts of the top flow guiding plate 247 and the bottom flow guiding plate 247 are triangular and circular respectively. Through the special shape design of the inner parts of the top flow guiding plate 247 and the bottom flow guiding plate 247 being triangular and circular respectively, it helps to guide and mix the fuel and air, optimize the air flow distribution inside the mixing chamber 242, improve the mixing efficiency, and make the combustion more sufficient and stable.

[0048] As Figure 4 shown, arc segments 8 are bolted to the front and rear sides of the top of the inner wall of the mixing chamber 242. A guiding segment 9 is arranged on the opposite side of the two arc segments 8, and an opening is arranged between the opposite sides of the two guiding segments 9. The bottom of the connecting pipe 243 is located at the opening. Through the arrangement of the arc segments 8 and the guiding segments 9, the air flow path inside the mixing chamber 242 is optimized, enabling the mixed gas to enter the connecting pipe 243 and the corrugated pipe 244 more smoothly, ensuring the stability and uniformity of fuel injection, and improving the effect of the combustion simulation.

[0049] Brief description of the usage process: When it is necessary to simulate different types of fire scenarios and change the shape of the combustion pool, the bidirectional lead screw 5 is driven to rotate by an externally connected drive motor. Since the slider 4 at the bottom of the moving side plate 21 is threadedly connected to the surface of the bidirectional lead screw 5, through the threaded fit between the two, the two sliders 4 on both sides can move relatively, and at the same time drive the two moving side plates 21 to move relatively. When the moving side plate 21 moves inward, the movable side plate 22 will rotate around the hinge connected to the moving side plate 21, and at the same time the movable side plate 22 will also drive the adjusting side plate 23 to rotate around the hinge between them, so as to change the shape of the entire simulated combustion pool structure 2 to meet the simulation requirements of different fire scenarios, such as fires in narrow spaces, open areas or irregular spaces. After the shape of the combustion pool is adjusted, fuel simulation combustion is ready to be carried out. The fuel injection assembly 24 starts to work. The gaseous fuel enters the shunt ring 246c through an external device, and then is sprayed into the straight section 246a through a plurality of shunt pipes 246f on the inner wall of the shunt ring 246c and the injection orifice plate 246d. At the same time, air enters from the bottom of the straight section 246a and mixes with the injected fuel in the straight section 246a. The spoiler columns 246e at the top of the inner wall of the straight section 246a will disrupt the air flow, making the fuel and air mix more fully. Then the mixed gas enters the mixing chamber 242 through the gradually expanding section 246b. In the mixing chamber 242, under the action of the two deflector plates 247 at the bottom, the air flow distribution is further optimized to achieve more complete mixing. Finally, the mixed gas enters the injection pipe 245 through the bellows 244 on the front and rear sides and the connecting pipe 243 on the top of the mixing chamber 242, and is finally sprayed into the combustion pool from the injection pipe 245 for combustion simulation. Since the bellows 244 is bolted to the adjusting side plate 23, when the adjusting side plate 23 moves as the shape of the combustion pool changes, the bellows 244 will expand and contract accordingly to ensure that the fuel injection area can cover the inside of the combustion pool and ensure the accuracy and stability of the combustion simulation.

[0050] Embodiment 2:

[0051] Reference Figure 1 、 7 、8, including a support 1, a simulated combustion pool structure 2 is provided on the top of the support 1, and fire extinguishing structures 3 are rotatably provided on both sides of the inner wall of the simulated combustion pool structure 2, and one side of the fire extinguishing structure 3 close to the inner wall of the simulated combustion pool structure 2 extends to the outside thereof. By providing the fire extinguishing structure 3, the fire extinguishing medium can be quickly transported to the combustion area, the fire can be controlled in time, the potential safety hazard can be reduced, and accurate fire extinguishing operations can be carried out according to different combustion situations and fire positions, enhancing the flexibility and adaptability of the fire extinguishing structure 3.

[0052] Such as Figure 7As shown in the figure, the fire extinguishing structure 3 includes a movable pipe 31. The movable pipe 31 is arranged on one side opposite to the two movable side plates 21 through a bearing seat. On the top of the opposite sides of the two movable side plates 21, input pipes 32 are bolted. And a plurality of connecting hoses 33 are connected to the top of the input pipe 32. The other side of the connecting hose 33 is communicated with the movable pipe 31. A plurality of spray nozzles 34 are communicated with one side opposite to the two movable pipes 31. On the opposite sides of the two movable side plates 21, support plates 35 are bolted. And a double-shaft motor 36 is bolted to the top of the support plate 35. And an adjusting component 37 is arranged at the output end of the double-shaft motor 36. The adjusting component 37 is used in cooperation with the movable pipe 31. By setting the fire extinguishing structure 3, the fire extinguishing medium is externally connected through the input pipe 32 and is conveyed into the movable pipe 31 through the connecting hose 33 and then sprayed from a plurality of spray nozzles 34, realizing fast and flexible fire extinguishing operations. The plurality of spray nozzles 34 can cover a large area. And at the same time of fire extinguishing, the double-shaft motor 36 and the adjusting component 37 can adjust the angles of the spray nozzles 34 according to the fire situation, improving the accuracy and efficiency of fire extinguishing.

[0053] As Figure 8 shown, the adjusting component 37 includes a gear 371. The gear 371 is sleeved on the surface of the movable pipe 31. And a rack 372 is meshed and connected to the bottom of the gear 371. One end of the rack 372 extends to the outside of the movable side plate 21 and is rotatably connected with a connecting rod 373. And a turntable 374 is rotatably connected to the rear side of the connecting rod 373. The rear side of the turntable 374 is bolted to the output end of the double-shaft motor 36. By setting the adjusting component 37, the double-shaft motor 36 drives the turntable 374 to rotate. When the turntable 374 rotates, the rack 372 is pulled to move linearly through the connecting rod 373. The movement of the rack 372 drives the gear 371 meshed with it to rotate. The gear 371 is sleeved on the movable pipe 31, thereby driving the movable pipe 31 to rotate, realizing the adjustment of the angle of the spray nozzle 34, enabling the spray nozzle 34 to accurately aim at the combustion area, improving the fire extinguishing effect, and enhancing the flexibility and adaptability of the fire extinguishing structure 3.

[0054] As Figure 7 shown, a filtering structure is arranged inside the spray nozzle 34, and the spray orifice of the spray nozzle 34 is fan-shaped. The filtering structure inside the spray nozzle 34 can prevent impurities from entering the spray nozzle 34, ensuring the normal operation and spraying effect of the spray nozzle 34; the spray orifice is fan-shaped, increasing the coverage area of the fire extinguishing medium and improving the fire extinguishing efficiency.

[0055] Brief description of the usage process: When a fire breaks out in the combustion chamber and fire extinguishing operations are required, the fire extinguishing medium enters through the input pipe 32 and is then transported to the movable pipe 31 through the connecting hose 33. Since the connecting hose 33 has a certain flexibility, it can adapt to the position changes of the movable pipe 31 during the adjustment process, ensuring the smooth transportation of the fire extinguishing medium. At this time, the nozzle 34 is in its initial position, and its nozzle is directed towards the inside of the combustion chamber. Multiple nozzles 34 are distributed on one side opposite to the two movable pipes 31, capable of covering a large area. Then, the output end of the double-axis motor 36 drives the turntable 374 to rotate. When the turntable 374 rotates, the rack 372 is pulled to move linearly through the connecting rod 373. Since the rack 372 meshes with the gear 371 sleeved on the surface of the movable pipe 31, the movement of the rack 372 will drive the gear 371 to rotate, and the rotation of the gear 371 will further drive the movable pipe 31 to rotate, realizing the adjustment of the angle of the nozzle 34. According to the specific situation and location of the fire, the double-axis motor 36 continuously operates, and the angle of the nozzle 34 is precisely adjusted through the adjustment assembly 37, so that the nozzle 34 can accurately aim at the combustion area. When the angle of the nozzle 34 is adjusted to the appropriate position, the fire extinguishing medium in the movable pipe 31 is ejected from the nozzle 34. Since a filtering structure is provided inside the nozzle 34, it can prevent impurities from entering the nozzle 34, ensuring the normal operation and spraying effect of the nozzle 34. At the same time, the nozzle of the nozzle 34 is fan-shaped, increasing the coverage area of the fire extinguishing medium, enabling the fire extinguishing medium to more effectively cover the combustion area, quickly control the fire, achieve efficient fire extinguishing, and improve the accuracy and efficiency of fire extinguishing.
