Description
Technical Field
[0001] This utility model belongs to the field of fire protection equipment technology and relates to a demonstration device for simulating fire rescue assessment. Background Technology
[0002] Firefighting and rescue work is of paramount importance, concerning people's lives and property safety. In order to effectively improve the professional skills and emergency response capabilities of firefighters, and at the same time enhance the fire safety awareness of the general public, demonstration devices simulating fire rescue assessments have emerged. These devices provide an intuitive and effective way for fire training and drills by simulating fire scenarios.
[0003] In use, most demonstration devices rely on external water pipes to simulate the fire extinguishing process. However, the conditions of demonstration sites are complex and varied. In some remote areas, temporary construction sites, or sites with special layouts, it is extremely inconvenient to connect external water pipes. For example, when conducting fire safety knowledge popularization demonstrations in mountainous areas, the lack of adequate water supply facilities may make it difficult to connect external water pipes, thus preventing the demonstration devices from operating normally and greatly limiting their application scope.
[0004] Meanwhile, some existing demonstration devices are seriously inadequate in terms of fire source setup and protection. They usually just use a simple shell to place the fire source inside. Once the fire source explodes, flames and burning materials can easily scatter out of the shell. In demonstration venues with dense crowds, this can easily cause direct harm to viewers, posing a significant safety hazard and failing to guarantee the safety of demonstration activities. Utility Model Content
[0005] The technical problem this utility model aims to solve is that in some remote areas, temporary construction sites, or sites with special layouts, it is extremely inconvenient to connect external water pipes, and once a fire source explodes, flames and burning materials are very likely to splatter out of the casing, which can easily cause direct injury to viewers.
[0006] The demonstration device for simulating fire rescue assessment described in this utility model includes a water-storing bottom shell and a simulation scene component. A hollow outer shell is fixedly connected to the top of the water-storing bottom shell. Several evenly distributed water leakage holes are opened on the top of the water-storing bottom shell. A partition is fixedly connected between the top and bottom of the inner wall of the water-storing bottom shell. A water supply mechanism is provided between the partition and one side of the inner wall of the water-storing bottom shell. A first sensor nozzle is installed on the top of the inner wall of the hollow outer shell. The top of the first sensor nozzle penetrates through the hollow outer shell and extends into the hollow outer shell. The water supply mechanism is connected to the first sensor nozzle. A filtration mechanism is provided inside the water-storing bottom shell. An anti-splash mechanism is provided on one side of the water-storing bottom shell.
[0007] Preferably, the simulated scene component includes a model with multiple layers. A second sensor nozzle is symmetrically installed on the top of the inner wall of the model.

[0008] Preferably, the water supply mechanism includes a water pump, which is installed between the partition and the inner wall of one side of the water storage bottom shell. The input end of the water pump is fixedly connected to a suction pipe, one end of which passes through the partition. The output end of the water pump is fixedly connected to a delivery pipe, the top end of which passes through the hollow shell and extends into the hollow shell to connect with the first sensor nozzle. A circular opening is provided on one side of the hollow shell. A three-way valve is installed on the side wall of the delivery pipe near the circular opening. A water distribution pipe is installed at one end of the three-way valve, and one end of the water distribution pipe passes through the hollow shell and extends into the hollow shell.
[0009] Preferably, the filtration mechanism includes a rectangular opening, a rectangular opening is provided on one side of the water storage bottom shell, a shell is slidably connected between the partition and the inner wall of one side of the water storage bottom shell, the top of the shell is not closed, filter cotton is provided inside the shell, a first handle is fixedly connected to one side of the shell through the rectangular opening and extending to the outside of the water storage bottom shell, and a number of evenly distributed drainage holes are provided at the bottom of the shell.
[0010] Preferably, the anti-splash mechanism includes slide rails, with multiple slide rails fixedly connected to both sides of the top of the hollow shell. A slide plate is slidably connected to the side wall of the slide rail. A circular plate is fixedly connected to the side of the slide plate away from the hollow shell. A support rod is movably connected to the side of the circular plate away from the hollow shell. A protective door panel is provided on one side of the hollow shell. The two sides of the protective door panel are movably connected to the ends of the support rod away from the circular plate near the bottom. A second handle is symmetrically fixedly connected to the side of the protective door panel away from the hollow shell near the bottom. A limit block is fixedly connected to the side of the circular plate away from the hollow shell near the bottom. The limit block is located below and in contact with the support rod.
[0011] Furthermore, a drain pipe is fixedly connected to one side of the bottom of the water storage shell, the drain pipe is connected to the inside of the water storage shell, and a valve is installed on the drain pipe.
[0012] Compared with the prior art, the beneficial effects of this utility model are:

It can effectively solve the problem of the inconvenience of external water pipes in some remote areas, temporary construction sites or special site layouts.
[0014] This utility model, through the cooperation of slide rails, support rods, protective door panels, and limiting blocks, enables the protective door panel to block the front of the water storage bottom shell during use, preventing the debris from flying towards the audience. Furthermore, if necessary, the fire source can be confined inside the hollow shell, blocking air circulation. This effectively solves the problem that once a fire source ignites, flames and burning materials can easily splatter out of the shell, causing direct harm to spectators. Attached Figure Description

[0030] like Figures 1-10As shown, the water supply mechanism includes a water pump 6. The water pump 6 is installed between the partition 5 and the inner wall of one side of the water storage bottom shell 1. The input end of the water pump 6 is fixedly connected to a suction pipe 7. One end of the suction pipe 7 passes through the partition 5. The output end of the water pump 6 is fixedly connected to a delivery pipe 8. The top end of the delivery pipe 8 passes through the hollow shell 2 and extends into the hollow shell 2 to connect with the first sensor nozzle 9. A circular opening 18 is provided on one side of the hollow shell 2. A three-way valve 10 is installed on the side wall of the delivery pipe 8 near the circular opening 18. A water distribution pipe 11 is installed at one end of the three-way valve 10. One end of the water distribution pipe 11 passes through the hollow shell 2 and extends into the hollow shell 2.
[0031] like Figures 1 to 7 As shown, the filtration mechanism includes a rectangular opening 12. A rectangular opening 12 is provided on one side of the water storage bottom shell 1. A shell 13 is slidably connected between the partition 5 and the inner wall of one side of the water storage bottom shell 1. The top of the shell 13 is not closed. Filter cotton 15 is provided inside the shell 13. A first handle 16 is fixedly connected to one side of the shell 13, which passes through the rectangular opening 12 and extends to the outside of the water storage bottom shell 1. Several evenly distributed drainage holes 14 are provided at the bottom of the shell 13.
[0032] The water pump 6 in this technical solution is a relatively mature induction motor pump in the prior art. It is started and stopped by sensing the water pressure in the water pipe. Its installation method and working principle are common knowledge among those in the field, so they will not be described in detail in this technical solution.
[0033] like Figures 1 to 8 As shown, the anti-splash mechanism includes slide rails 19. Multiple slide rails 19 are fixedly connected to both sides of the top of the hollow shell 2. Slide plates 20 are slidably connected to the side walls of the slide rails 19. A circular plate 21 is fixedly connected to the side of the slide plate 20 away from the hollow shell 2. A support rod 22 is movably connected to the side of the circular plate 21 away from the hollow shell 2. A protective door panel 24 is provided on one side of the hollow shell 2. The two sides of the protective door panel 24 are movably connected to the ends of the support rod 22 away from the circular plate 21 near the bottom. A second handle 25 is symmetrically fixedly connected to the side of the protective door panel 24 away from the hollow shell 2 near the bottom. A limit block 23 is fixedly connected to the side of the circular plate 21 away from the hollow shell 2 near the bottom. The limit block 23 is located below and in contact with the support rod 22.
[0034] During operation, first place the water storage tank 1 in the desired location. Next, fill the tank with an appropriate amount of water. If a water pipe connection is convenient, it can be connected to the drain pipe 17 to deliver water into the tank. If no water pipe connection is available, other water sources can be poured into the top of the tank. This water will enter the tank through the drain hole 4. When there is sufficient water, a simulation demonstration can be conducted. First, pull up the protective door panel 24 using the second handle 25 to open the hollow outer shell 2. Place the item to be ignited on top of the tank. Then, lower the protective door panel 24 so that it is positioned in front of the tank. To prevent the ignited item from exploding, pull the protective door panel 24 away from the hollow outer shell 2, increasing the distance between them. This allows the worker to stand in front of the protective door panel 24 or to one side of the hollow outer shell 2 to ignite the item. The burning material burns inside the hollow shell 2. When the temperature inside the hollow shell 2 reaches a certain level, the glass component on the first sensor nozzle 9 will break. Simultaneously, the water pump 6 will start, drawing water from the water storage bottom shell 1 into the water pump 6 through the water suction pipe 7 and then delivering it to the first sensor nozzle 9 through the delivery pipe 8 and the three-way valve 10. The first sensor nozzle 9 will then spray the water towards the fire source to extinguish the fire. The sprayed water will pass through the drain hole 4 to the filter cotton 15, and after being filtered by the filter cotton 15, it will flow back into the water storage bottom shell 1 through the drain hole 14. This process can be repeated to recycle the water in the water storage bottom shell 1. If the fire source becomes uncontrollable or other situations occur, the protective door 24 can be pushed with other tools to slide multiple round plates 21 towards the back of the water storage bottom shell 1, causing the protective door 24 to close the hollow shell 2. This prevents air from entering the hollow shell 2 and quickly extinguishes the fire source, effectively improving its safety. Example
[0035] like Figures 9-10 As shown, the simulation scene component includes model 3, which has multiple layers. A second sensor nozzle 26 is symmetrically installed on the top of the inner wall of model 3. The top of the second sensor nozzle 26 penetrates through model 3 and extends to the top of model 3. A three-way pipe 28 is installed on the top of model 3. Connecting pipes 27 are fixedly connected to the output ends on both sides of the three-way pipe 28. One end of the connecting pipe 27 is connected to the second sensor nozzle 26.
[0036] During operation, when a multi-story building fire demonstration is required, the protective door panel 24 can be opened upwards, and the entire model 3 can be placed inside the hollow shell 2. Next, the existing general-purpose water pipes are connected to both the branch water pipe 11 and the tee pipe 28, connecting the tee pipe 28 to the branch water pipe 11. Then, the handle on the tee valve 10 is turned to connect the branch water pipe 11 to the delivery pipe 8. The model 3 has multiple floors, and the doors and windows on each floor are in different states, some closed and some open. Only some rooms are equipped with the second sensor sprinkler head 26, allowing observation of areas with and without the second sensor sprinkler head 26 between the multi-story buildings. The model distinguishes between closing and opening doors and windows. Next, the model is ignited using the ignition device on model 3. When the temperature inside model 3 reaches a certain level, the glass on the second sensor nozzle 26 will break. Simultaneously, the water pump 6 starts and delivers water through the water distribution pipe 11 and the connected water pipe to the three-way pipe 28. The three-way pipe 28 then delivers water to the second sensor nozzle 26 through the connecting pipe 27. The second sensor nozzle 26 sprays water towards the fire source. At this time, the simulated fire situation on multiple floors of model 3 can be viewed simultaneously. The sprayed water can flow into the water storage bottom shell 1 through the water leakage hole 4 for recycling. The above operation can increase the simulation demonstration of various fire scenarios.
[0037] Working Principle: When using this technical solution, first place the water storage shell 1 in the desired location. Next, fill the water storage shell 1 with an appropriate amount of water. If convenient, connect it to the drain pipe 17 to deliver water into the water storage shell 1. If there is no water pipe connection available, pour water from another source onto the top of the water storage shell 1. This water will enter the water storage shell 1 through the drain hole 4. When there is sufficient water, a simulation demonstration can be conducted. First, pull up the protective door panel 24 using the second handle 25 to open the hollow outer shell 2. Place the item to be ignited on top of the water storage shell 1, then lower the protective door panel 24 so that it is positioned in front of the water storage shell 1. Next, to prevent the ignited item from exploding, pull the protective door panel 24 away from the hollow outer shell 2, increasing the distance between them. This allows the operator to stand in front of the protective door panel 24 or to one side of the hollow outer shell 2 to ignite the item. When ignited, the ignited object burns inside the hollow shell 2. When the temperature inside the hollow shell 2 reaches a certain level, the glass component on the first sensor nozzle 9 will break. Simultaneously, the water pump 6 starts, drawing water from the water storage bottom shell 1 into the water pump 6 through the water suction pipe 7, and then delivering it to the first sensor nozzle 9 through the delivery pipe 8 and the three-way valve 10. The first sensor nozzle 9 then sprays the water towards the fire source to extinguish the fire. The sprayed water passes through the drain hole 4 to the filter cotton 15, and after being filtered by the filter cotton 15, it flows back into the water storage bottom shell 1 through the drain hole 14. This process can be repeated to recycle the water in the water storage bottom shell 1. If the fire source becomes uncontrollable or other situations occur, the protective door panel 24 can be pushed with other tools to slide multiple round plates 21 towards the back of the water storage bottom shell 1, causing the protective door panel 24 to close the hollow shell 2. This prevents air from entering the hollow shell 2, quickly extinguishing the fire source and effectively improving its safety.
[0038] When a multi-story building fire demonstration is needed, the protective door panel 24 can be opened upwards, and the entire model 3 can be placed inside the hollow shell 2. Next, the existing general-purpose water pipes are connected to both the branch water pipe 11 and the tee pipe 28, connecting the tee pipe 28 to the branch water pipe 11. Then, the handle on the tee valve 10 is turned to connect the branch water pipe 11 to the delivery pipe 8. Model 3 has multiple floors, and the doors and windows on each floor are in different states, some closed and some open. Only some rooms are equipped with the second sensor sprinkler head 26. This allows observation of the difference between multi-story buildings with and without the second sensor sprinkler head 26. The difference between closing and opening doors and windows is explained. Next, the ignition device on model 3 is used to ignite the fire. When the temperature inside model 3 reaches a certain level, the glass on the second sensor nozzle 26 will break. Simultaneously, the water pump 6 starts and delivers water through the water distribution pipe 11 and the connected water pipe to the three-way pipe 28. Then, the three-way pipe 28 delivers water to the second sensor nozzle 26 through the connecting pipe 27. The second sensor nozzle 26 sprays water towards the fire source. At this time, the simulated fire situation on multiple floors of model 3 can be viewed simultaneously. The sprayed water can flow into the water storage bottom shell 1 through the water leakage hole 4 for recycling. The above operation can increase the simulation demonstration of various fire scenarios.
