[0020] Beneficial effects of the utility model:

[0021] The utility model provides a firefighting training device, comprising a housing, a supporting partition structure, and a smoke filter. A combustion space is formed within the housing. The housing is further provided with an injection port, an air inlet duct, and an air outlet duct connected to the combustion space. The supporting partition structure is disposed at the connection point between the combustion space and the air inlet duct. The supporting partition structure includes a plurality of partitions, each rotatably connected to the housing and having a first operating state and a second operating state. When the partitions are in the first operating state, the partitions are disposed at the connection point between the combustion space and the air inlet duct, and a first ventilation duct is formed between any two adjacent partitions, with both the combustion space and the air inlet duct connected to the first ventilation duct. When the partitions are in the second operating state, the partitions are erected at the connection point between the combustion space and the air inlet duct, and a second ventilation duct is formed between any two adjacent partitions, with both the combustion space and the air inlet duct connected to the second ventilation duct. The ventilation cross-sectional area of ​​the second ventilation duct is greater than the ventilation cross-sectional area of ​​the first ventilation duct. The flue gas filter is arranged at the connection point between the combustion space and the air outlet duct.

[0022] This firefighting training device, by providing multiple partitions, has a first operating state in which the partitions are laid at the connection point between the combustion space and the air inlet duct, and a second operating state in which the partitions are erected at the connection point between the combustion space and the air inlet duct. It is understood that when the multiple partitions are laid at the connection point between the combustion space and the air inlet duct, the multiple partitions are equivalent to forming a support plate that can support the burning material, and the first ventilation duct between any two adjacent partitions allows outside air to enter the combustion space, thereby allowing the burning material to continue burning. When the multiple partitions are erected at the connection point between the combustion space and the air inlet duct, the second ventilation duct between any two adjacent partitions is used for both ventilation and to allow the burning material to fall out of the combustion space.

[0023] When practicing the use of a fire extinguisher, first adjust the multiple baffles to the first working state. Then, pile the burning material on the support plate formed by the multiple baffles and ignite the burning material. Then, insert the nozzle of the fire extinguisher through the nozzle into the combustion space to spray dry powder fire extinguishing agent onto the burning material. During the spraying of the dry powder fire extinguishing agent, the smoke in the combustion space and the dry powder fire extinguishing agent mix. A smoke filter is installed at the connection between the combustion space and the air outlet duct. The smoke filter filters the dry powder fire extinguishing agent in the smoke and discharges the smoke to the outside through the air outlet duct. This effectively alleviates the problem of dry powder fire extinguishing agent spreading in the air and affecting the health and environment of trainees based on good training in the use of fire extinguishers, and effectively avoids the risk of burns to trainees caused by burning materials.

[0024] After the burning object is extinguished by the fire extinguisher, the multiple partitions are adjusted to the second working state, so that the burning object falls out of the combustion space. This makes it easy to clean up the burning object and facilitates later practical training on how to use the fire extinguisher.

[0025] Therefore, by adopting this fire-fighting training device, on the basis of good training on the use of fire extinguishers, the problem of dry powder fire extinguishing agent spreading in the air affecting the health of trainees and the environment can be effectively alleviated, and the risk of burning trainees by burning materials can be effectively avoided; secondly, it is convenient to clean up the burning materials after burning.

They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation.

[0043] Figure 1 This is the front view of the fire-fighting training device. Figure 2 This is the right side view of the fire-fighting training device. Figure 3 This is a top view of the fire-fighting training device. Figure 4 It is a structural schematic diagram of the support and partition structure 2 assembled on the box body 1. Figure 4 The multiple partitions 21 are all laid at the connection point between the combustion space 11 and the air inlet duct 13, and a first ventilation duct is formed between any two adjacent partitions 21.

[0044] The correct use of fire extinguishers is of great significance in improving fire extinguishing efficiency, reducing economic losses and casualties. Therefore, the ability to use fire extinguishers correctly should be a basic ability that personnel in production and living places should possess, and regular training on the use of fire extinguishers is also essential. At present, fire extinguishers are mainly divided into dry powder fire extinguishers, water-based fire extinguishers and gas fire extinguishers. Among them, dry powder fire extinguishers are widely used in various places due to their good fire extinguishing performance, wide range of applications and low operational risk level. However, during the practical training of dry powder fire extinguishers, the dry powder fire extinguishing agent in the dry powder fire extinguisher will diffuse in the air, which may affect the health of the trainees and pollute the environment.

[0045] Therefore Figure 1-4 As shown, the utility model provides a fire-fighting training device, which includes a housing 1, a supporting partition structure 2 and a smoke filter 3. A combustion space 11 is formed inside the housing 1. The housing 1 is also provided with an injection port 12, an air inlet duct 13 and an air outlet duct 14 connected to the combustion space 11. The supporting partition structure 2 is arranged at the connection point between the combustion space 11 and the air inlet duct 13; the supporting partition structure 2 includes a plurality of partitions 21, and the plurality of partitions 21 are all rotatably connected to the housing 1 and have a first working state and a second working state. When the plurality of partitions 21 are in the first working state, the plurality of partitions 21 are all laid at the connection point between the combustion space 11 and the air inlet duct 13, and a first ventilation duct is formed between any two adjacent partitions 21, and the combustion space 11 and the air inlet duct 13 are both connected to the first ventilation duct. When the multiple baffles 21 are in the second operating state, they are all erected at the junction between the combustion space 11 and the air inlet duct 13. A second ventilation duct is formed between any two adjacent baffles 21, connecting the combustion space 11 and the air inlet duct 13. The second ventilation duct has a larger cross-sectional area than the first ventilation duct. A flue gas filter 3 is located at the junction between the combustion space 11 and the air outlet duct 14.

[0046] By providing multiple partitions 21, the firefighting training device has a first operating state in which the partitions 21 are laid at the connection point between the combustion space 11 and the air inlet duct 13, and a second operating state in which the partitions 21 are erected at the connection point between the combustion space 11 and the air inlet duct 13. It is understood that when the partitions 21 are laid at the connection point between the combustion space 11 and the air inlet duct 13, the partitions 21 form a support plate that supports the burning material, and the first ventilation duct between any two adjacent partitions 21 allows outside air to enter the combustion space 11, thereby maintaining combustion. When the partitions 21 are erected at the connection point between the combustion space 11 and the air inlet duct 13, the second ventilation duct between any two adjacent partitions 21 serves both as ventilation and allows the burning material to fall out of the combustion space 11.

[0047] When practicing the use of a fire extinguisher, first adjust the multiple partitions 21 to the first working state, then pile the combustible material on the support plate formed by the multiple partitions 21 and ignite the combustible material. Then, insert the nozzle of the fire extinguisher into the combustion space 11 through the injection port 12 to spray dry powder fire extinguishing agent onto the combustible material. During the spraying of the dry powder fire extinguishing agent, the smoke in the combustion space 11 mixes with the dry powder fire extinguishing agent. A smoke filter 3 is provided at the connection between the combustion space 11 and the air outlet duct 14. The smoke filter 3 filters the dry powder fire extinguishing agent in the smoke and discharges the smoke to the outside through the air outlet duct 14. This effectively alleviates the problem of dry powder fire extinguishing agent spreading in the air and affecting the health and environment of the trainees based on good training in the use of a fire extinguisher, and effectively avoids the risk of burns to the trainees caused by the combustible material.

[0048] After the burning object is extinguished by the fire extinguisher, the plurality of partitions 21 are adjusted to the second working state so that the burning object falls out of the combustion space 11. This facilitates the cleaning of the burning object and facilitates the subsequent practical training on how to use the fire extinguisher.

[0049] Therefore, by adopting this fire-fighting training device, on the basis of good training on the use of fire extinguishers, the problem of dry powder fire extinguishing agent spreading in the air affecting the health of trainees and the environment can be effectively alleviated, and the risk of burning trainees by burning materials can be effectively avoided; secondly, it is convenient to clean up the burning materials after burning.

[0050] Specifically, if Figure 4 As shown, when multiple partitions 21 are installed at the connection point between the combustion space 11 and the air inlet duct 13, the partitions 21 are laid flat on the same plane. This plane is the plane where the connection point between the combustion space 11 and the air inlet duct 13 is located. It will be understood that in this case, any two adjacent partitions 21 do not touch. The gap between any two adjacent partitions 21 constitutes the first ventilation duct.

[0051] Furthermore, if Figure 4 As shown, the plurality of partitions 21 form a support plate, and there is a gap between the outer periphery of the support plate and the inner peripheral wall of the box body 1. It is also convenient for outside air to enter the combustion space 11, so that the combustion material can keep burning.

[0052] As an alternative, when multiple partitions 21 are installed at the junction between the combustion space 11 and the air inlet duct 13, the adjacent portions of any two adjacent partitions 21 are stacked. Each stacked portion is roughly distributed within the same thickness region. This thickness region is the area where the connection between the combustion space 11 and the air inlet duct 13 is located. It will be understood that in this case, the stacked portions of any two adjacent partitions 21 may or may not touch. The gap between any two adjacent partitions 21 stacked together constitutes the first ventilation duct.

[0053] Specifically, in this embodiment, the housing 1 is further provided with a second drawer opening for communication with the outside world. The second drawer opening is located at the connection point between the combustion space 11 and the air outlet duct 14. The smoke filter 3 is inserted into the housing 1 through the second drawer opening, making it easier to clean and replace the smoke filter 3.

[0054] Specifically, in this embodiment, Figure 1 As shown, the air inlet duct 13 is provided with an air inlet 132 , and the air inlet 132 is protruded from the outside of the box body 1 .

[0055] Preferably, if Figure 1 As shown, the air outlet duct 14, combustion space 11, supporting partition structure 2, and air inlet duct 13 are arranged sequentially from top to bottom along the height direction of the box body 1. Since the smoke generated by the combustion of the combustible material has a high temperature and low density, the smoke tends to float upward along the height direction of the box body 1. Therefore, this arrangement allows for better air intake and efficient exhaust of smoke.

[0056] As an alternative, the air outlet duct 14, combustion space 11, and air inlet duct 13 can be arranged to be roughly distributed within the same height region along the height direction of the housing 1. It is understood that when the multiple partitions 21 are in the first operating state, the air outlet duct 14, combustion space 11, first ventilation duct, and air inlet duct 13 are sequentially connected. Furthermore, when the multiple partitions 21 are in the second operating state, the air outlet duct 14, combustion space 11, second ventilation duct, and air inlet duct 13 are sequentially connected.

[0057] Among them, such as Figure 1 、 Figure 2 and Figure 4 As shown, the supporting partition structure 2 also includes a connecting rod 22 and an operating handle 23. The connecting rod 22 is rotatably connected to the multiple partitions 21 along one side of the orientation, which is the arrangement direction of the multiple partitions 21 when they are in the second working state. The operating handle 23 passes through the box body 1 and is fixedly connected to one of the partitions 21. Rotating the operating handle 23 causes the connected partition 21 to rotate, driving the connecting rod 22 to move, and thus driving the multiple partitions 21 to rotate synchronously. This allows the multiple partitions 21 to be adjusted to switch between the first working state and the second working state.

[0058] Specifically, the operating handle 23 is rotatably connected to the housing 1 via a bearing. The partition 21 is rotatably connected to the housing 1 via a bearing or a rotating shaft.

[0059] As an alternative, the operating handle 23 is in transmission connection with a motor. The motor can drive the operating handle 23 to rotate about its own central axis, so as to electrically control the plurality of partitions 21 to switch between the first working state and the second working state.

[0060] As another alternative, the supporting partition structure 2 further includes an operating handle 23, a rack and a plurality of gears. The rack is slidably arranged on the housing 1. The plurality of gears are engaged with the rack. The plurality of gears are arranged in a one-to-one correspondence with the plurality of partitions 21 and are fixedly connected. The operating handle 23 passes through the housing 1 and is fixedly connected to the rack. The operating handle 23 drives the rack to slide in a directional manner, so as to drive the plurality of gears to engage with the rack synchronously, thereby driving the plurality of partitions 21 to rotate synchronously. It is also possible to adjust the plurality of partitions 21 to switch between the first working state and the second working state.

[0061] It can be understood that the transmission structure for adjusting multiple partitions 21 to rotate synchronously and switch between the first working state and the second working state can also be replaced by other transmission structures that can adjust multiple partitions 21 to rotate synchronously and switch between the first working state and the second working state.

[0062] The fire-fighting training device further comprises an exhaust fan, the input end of which is connected to the output end of the air outlet duct 14. The exhaust fan can accelerate the separation of smoke and dry powder fire extinguishing agent and accelerate the discharge of smoke.

[0063] Among them, the air outlet duct 14 is provided with an air compensation port connected to the outside world. The fire-fighting training device also includes an air compensation structure 4. The air compensation structure 4 includes a cover 41 rotatably connected to the box body 1. The cover 41 can selectively open or block the air compensation port. Specifically, during the exhaust fan exhaust process, if the smoke filter 3 is blocked, the cover 41 opens the air compensation port under the suction force of the exhaust fan to compensate for the exhaust volume of the exhaust fan, so as to ensure that the exhaust fan can exhaust normally and avoid damage to the exhaust fan. Secondly, the cover 41 opens the air compensation port to remind the trainee that the smoke filter 3 is blocked, so that the trainee can clean or replace the smoke filter 3 in time, and can remind the trainee to turn off the exhaust fan in time.

[0064] Specifically, if Figure 1 As shown, the cover 41 is located in the air outlet duct 14. The air compensation structure 4 includes an elastic member 42, which is located outside the housing 1. One end of the elastic member 42 is fixedly connected to the housing 1, and the other end is fixedly connected to the cover 41. The suction force of the exhaust fan can drive the cover 41 to open the air compensation port. The elastic recovery force of the elastic member 42 can pull the cover 41 to block the air compensation port. Specifically, during the exhaust fan's exhaust process, if the smoke filter 3 becomes clogged, the cover 41 opens the air compensation port under the action of the exhaust fan's suction force to compensate for the exhaust volume of the exhaust fan, thereby ensuring that the exhaust fan can exhaust air normally and avoiding damage to the exhaust fan. During this process, the elastic member 42 is stretched and elastically deformed. If the exhaust fan stops exhausting, the elastic member 42 pulls the cover 41 to block the air compensation port under the action of its own elastic recovery force. This allows the air compensation port to be selectively opened or blocked.

[0065] Furthermore, if Figure 1 As shown, the connection between the elastic member 42 and the cover 41 is the first connection. The connection where the cover 41 is rotatably connected to the housing 1 is the second connection. Preferably, the first connection is farther from the output end of the air outlet duct 14 than the second connection. This improves the effect of the elastic member 42 pulling the cover 41 to block the air compensation port.

[0066] In this embodiment, if Figure 1 As shown, the elastic member 42 is a spring.

[0067] Alternatively, as Figure 1 and Figure 2 As shown, the firefighting training device also includes a waste box 5. The air inlet duct 13 is provided with a first drawer opening that connects to the outside world. The waste box 5 is inserted into the air inlet duct 13 through the first drawer opening and is located directly below the supporting partition structure 2. This arrangement ensures that burning materials that fall out of the combustion space 11 fall into the waste box 5, facilitating the removal of burned materials and further preventing burns to trainees. Furthermore, the waste box 5 is connected to the housing 1 by plugging, making it easy to install and remove.

[0068] Alternatively, as Figure 1 and Figure 2 As shown, the housing 1 is further provided with a water injection hole 15 in communication with the combustion space 11. The water injection hole 15 is connected to a water source and can selectively spray water into the combustion space 11. Specifically, during practical training on how to use a fire extinguisher, the water injection hole 15 is controlled to spray water into the combustion material in the combustion space 11 while spraying dry powder fire extinguishing agent into the combustion material, thereby improving fire extinguishing efficiency.

[0069] Specifically, if Figure 1 and Figure 2 As shown, the bottom of the sewage box 5 is provided with a first leakage hole, and the air inlet duct 13 is provided with a second leakage hole 131, which is located below the first leakage hole. It is understood that the first leakage hole and the second leakage hole 131 are connected through the air inlet duct 13. Specifically, during the process of spraying dry powder fire extinguishing agent onto the burning material, water is simultaneously sprayed onto the burning material, and the water in the combustion space 11 flows into the sewage box 5 and / or the air inlet duct 13 through the first ventilation duct. By providing the first leakage hole, the water in the sewage box 5 flows through the first leakage hole, the air inlet duct 13, and the second leakage hole 131 in sequence and flows out of the fire-fighting training device. By providing the second leakage hole 131, the water in the air inlet duct 13 flows out of the fire-fighting training device through the second leakage hole 131. Secondly, when cleaning the fire-fighting training device, the water in the box body 1 can also flow out smoothly through the first leakage hole, the air inlet duct 13, and the second leakage hole 131.

[0070] Alternatively, as Figure 1As shown, a thermal insulation layer 6 is provided around at least the combustion space 11 of the housing 1 to further reduce the risk of burns to trainees. In this embodiment, the thermal insulation layer 6 is provided around the combustion space 11 of the housing 1. The thickness of the thermal insulation layer 6 is 10 mm. A 1 mm thick iron sheet is also provided around the thermal insulation layer 6. The thermal insulation layer 6 is made of rock wool.

[0071] Alternatively, as Figure 1 and Figure 2 As shown, the bottom of the box body 1 is provided with rollers 7 along the height direction. It is convenient to move the fire fighting training device. Figure 1 and Figure 2 As shown, the exemplary number of rollers 7 is four, and the four rollers 7 are respectively located at the four corners of the box body 1 .

[0072] In this embodiment, the housing 1 is exemplarily made of cast iron. The wall thickness of the portion of the housing 1 corresponding to the combustion space 11 is 10 mm. The wall thickness of the portion of the housing 1 corresponding to the air inlet duct 13 and the air outlet duct 14 is 3 mm. It will be appreciated that other metal materials may also be used to make the housing 1.

[0073] In this embodiment, the exemplary setting of the combustion space 11 includes a first subspace and a second subspace that are connected to each other. The first subspace is also connected to the air inlet duct 13, and the second subspace is also connected to the air outlet duct 14. The supporting partition structure 2 is arranged at the connection between the first subspace and the air inlet duct 13. The smoke filter 3 is arranged at the connection between the second subspace and the air outlet duct 14. The first subspace and the second subspace are both square spaces. The part of the box body 1 corresponding to the first subspace is a square box body of 950mm×950mm×900mm. The part of the box body 1 corresponding to the second subspace is a square box body of 580mm×580mm×450mm. It can be understood that the volume and shape of the box body 1, the volume and shape of the combustion space 11, the volume and shape of the air inlet duct 13, and the volume and shape of the air outlet duct 14 can all be adaptively set according to actual working conditions.

[0074] In this embodiment, the injection port 12 is exemplarily set to be a square injection port of 400 mm×400 mm. It is understandable that the size of the injection port 12 can also be adaptively set according to actual working conditions.

[0075] In this embodiment, the smoke filter 3 is exemplarily made of 304 stainless steel. The smoke filter 3 is a multi-layer mesh filter. It is understood that other types of filters can also be used as long as they can filter and separate the dry powder fire extinguishing agent in the smoke.

[0076] In this embodiment, the exhaust fan is exemplarily set to be a high-temperature axial flow fan. The speed of the high-temperature axial flow fan is 2900r / min, the wind pressure range is: 321Pa~473Pa, and the flow range is: 1.29m 3 / s~105m 3 / s, power range: 1.1KW ~ 2.2KW. The power supply line of the high-temperature axial flow fan passes through the wire tube 8 fixed on the outside of the iron sheet and is connected to the power supply. The diameter of the wire tube 8 is 3mm.

[0077] In this embodiment, the diameter of the water injection hole 15 is exemplarily set to 65 mm.
