Description

Technical Field

[0001] This invention belongs to the field of fire safety education technology, specifically an auxiliary device for indoor fire extinguisher training exercises. Background Technology

[0002] Fire safety education and awareness campaigns are crucial to fire prevention efforts. These campaigns aim to disseminate fire safety knowledge to the public, educate them on fire prevention, and reduce the harm that fires pose to people's lives and property. Fire safety education and awareness campaigns are often conducted through lectures and interactive experiences.

[0003] The existing science popularization methods used in lectures mainly involve science popularizers playing science videos, explaining science knowledge, and demonstrating the use of fire-fighting equipment. This approach is monotonous, lacks interactivity, and fails to stimulate the learning interest of the audience, resulting in poor science popularization effects.

[0004] To enhance the interactivity of the science popularization process, stimulate the learning interest of the learners, and improve the effectiveness of science popularization, immersive fire extinguishing systems are often used in existing technologies for interactive experiences in fire safety education. Compared with interactive experiences using real flames, this method can avoid the problem of real flames easily causing harm to users. However, the fire situation in this method is mostly simulated through virtual scenes, which makes it difficult to provide users with a realistic visual and tactile experience of flames. This may make it difficult for users to have a realistic feeling about fire, thus limiting the effectiveness of fire safety education and publicity. Summary of the Invention

[0005] The purpose of this invention is to provide an auxiliary device for indoor fire extinguisher training and drills, which solves the problem that existing immersive fire extinguishing systems used for fire safety education make it difficult for users to have a realistic experience of fire, thus affecting the progress of subsequent education work.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: An auxiliary device for indoor fire extinguisher training exercises includes an open-top simulation box and several simulated fire extinguishers. Each simulated fire extinguisher contains several particles, and the weight and particle size of the particles in each simulated fire extinguisher are different. The open-top simulation box contains a fire simulation component, which includes several connecting boxes. Each connecting box is connected to a set of simulation tubes, and each set of simulation tubes has a different length. The simulation tubes are all made of elastic material, and each simulation tube has several first holes on its side wall. Each first hole has a baffle plate made of elastic material fixedly connected to its side wall. Each connecting box has several second holes. The bottom wall of the open-top simulation box contains a coil. The output end of the coil is connected to a water pump. The output end of the water pump is connected to the input end of the coil. The side wall of the coil is wound with an electric heating wire and a blower pipe. The input end of each connecting box is connected to the output end of the blower pipe. The input end of the blower pipe is connected to a first air pump. The first air pump is fixedly connected to the open-top simulation box. A horn is installed inside the open-top simulation box.

[0007] It also includes a control system, which controls the operation of the water pump, heating element, first air pump, and horn.

[0008] Furthermore, the control system includes temperature sensors and controllers;

[0009] Temperature sensors are used to collect temperature information of the coil;

[0010] The controller is used to receive type information input by the user and control the water pump, the first air pump and the horn to work according to the type information, and to control the heating wire to work according to the temperature information and type information.

[0011] The technical principle and beneficial effects of the above scheme are as follows: This device simulates the shape of a flame by blowing air into the simulation tube, causing the simulation tube to stand upright and swing under the action of air pressure, simulating the temperature of the fire scene by adjusting the temperature of the liquid in the coil, and simulating the color of the flame by illuminating the simulation tube with a spotlight.

[0012] Simultaneously, by adjusting the operating power of the first air pump, the speed of the air ejected from the first hole is adjusted, thereby filtering the weight of the particles entering the first hole. Furthermore, by changing the angle of the baffle based on the speed of the air ejected from the first hole, the particle size of the particles entering the first hole is filtered, ensuring that only the correct particles from the simulated fire extinguisher can pass through the first hole into the simulated tube, blocking the connection between the simulated tube and the connecting box. Subsequently, the amount of air entering the simulated tube decreases, causing the simulated tube to collapse, thus simulating the effect of extinguishing a fire.

[0013] By setting up a second hole, the air velocity ejected from the first hole increases after the second hole is blocked, thus simulating the effect of exacerbating a fire when the extinguishing position is incorrect.

[0014] Compared to existing technologies that use virtual scenarios for simulation, this device can provide users with a more realistic fire extinguishing experience.

[0015] Furthermore, the open-top simulation chamber has several collection chambers on its side wall, and each collection chamber has several third holes on its side wall near the simulation tube. The open-top simulation chamber is equipped with a second air pump, and each collection chamber is connected to the second air pump.

[0016] Beneficial effects: This device, through the setting of a collection chamber and a second air pump, generates negative pressure to collect particles in the open-top simulation box. This allows the device to collect particles from the open-top simulation box more comprehensively, reducing particle waste and also reducing the work steps for subsequent science popularization personnel.

[0017] Furthermore, spotlights for simulating firelight are fixedly connected to the bottom wall of the simulation tube, and the controller controls the operation of the spotlights according to the type information.

[0018] Beneficial effects: The spotlights in this device can further simulate the flames in a fire. At the same time, after the particles enter the simulation tube, they will also block the lamp tubes of the spotlights. Compared with the solution without spotlights, this device can simulate the changes in flames during the process of extinguishing a fire, making this device closer to the fire scene.

[0019] Furthermore, each of the simulation tubes is fixedly connected to a diaphragm, which divides the simulation tube into an upper chamber that communicates with the connection box and a lower chamber containing a predetermined portion.

[0020] Beneficial effects: The diaphragm in this device can prevent particles from entering the spotlight. Compared with the solution without a diaphragm, this solution can prevent particles from entering the spotlight and causing damage, thereby shortening the life of the device. At the same time, it can also prevent particle loss and increase the operating cost of the device.

[0021] Furthermore, the control system also includes a camera, which is used to collect image information inside the open-top simulation chamber, and the controller controls the horn to work based on the image information.

[0022] Beneficial effects: This device monitors the status of the simulated fire extinguisher by collecting image information from a camera, thereby evaluating the simulated fire extinguisher selected by the user and the fire extinguishing process, and providing prompts to the user through a loudspeaker. Compared with prompts from science popularization personnel or users judging based on the status of the simulated fire extinguisher themselves, this device can provide timely feedback to users, enhance interaction with users, and thus achieve the purpose of popularizing fire safety knowledge among users.

[0023] Furthermore, an ultrasonic detector is installed on the inner wall of the open-top simulation chamber. The ultrasonic detector is used to collect the concentration information of particles inside the open-top simulation chamber, and the controller controls the operation of the second air pump based on the concentration information.

[0024] Beneficial effects: This device monitors the concentration of particles inside the open-top simulation chamber using an ultrasonic detector. When the particle concentration inside the chamber is too high, it controls the second air pump to collect the particles, thus preventing the high particle concentration from affecting the user's health.

[0025] Furthermore, filters are fixedly connected to the connection points between the blower pipe and the connecting box.

[0026] Beneficial effects: By incorporating a filter, this device reduces particle waste caused by particles entering the blower pipe from the connection box, compared to solutions without a filter, thus lowering the operating cost of the device.

[0027] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0037] The following detailed description illustrates the specific implementation method:

[0038] Implementation, for example, attached Figure 1-5 As shown: An auxiliary device for indoor fire extinguisher training exercises includes an open-top simulation box 1 and several simulated fire extinguishers 7. Each simulated fire extinguisher 7 contains several particles, and the weight and particle size of the particles in each simulated fire extinguisher 7 are different. The open-top simulation box 1 contains a fire simulation component 2, which includes several connecting boxes 24, and each connecting box 24 is connected to a set of simulated tubes 23. Each set of simulated tubes 23 has a different length and is made of an elastic material. The material of the simulated tubes 23 is preferably artificial protein fiber, and several first holes are opened on the side walls of the simulated tubes 23. The side walls of the first holes are all bonded and fixed with elastic material. The baffle 233 and the connecting box 24 each have several second holes. The bottom wall of the open-top simulation box 1 is equipped with a coil 21 containing a solution. The output end of the coil 21 is connected to a water pump, preferably made of 25LG3-10×3 material. The output end of the water pump is connected to the input end of the coil 21. The side wall of the coil 21 is wound with heating wire and a blower pipe 22. The input end of the connecting box 24 is connected to the output end of the blower pipe 22. The input end of the blower pipe 22 is connected to a first air pump 25, preferably a DQE1100 model. The first air pump 25 is fixedly connected to the open-top simulation box 1 by bolts. The open-top simulation box 1 is equipped with a horn 3.

[0039] It also includes a control system, which comprises a temperature sensor and a controller. The temperature sensor is used to collect temperature information of the coil 21 and is located on the outer wall of the coil. The controller receives type information input by the user and controls the operation of the water pump, the first air pump 25, and the horn 3 according to the type information, and controls the operation of the heating wire according to the temperature and type information. The preferred model of the temperature sensor is 718-272969-001. The preferred model of the controller is 2080Micro850. The temperature sensor, water pump, first air pump 25, and horn 3 are all electrically connected to the controller.

[0040] In this embodiment, the side wall of the open-top simulation box 1 has several collection chambers, and each collection chamber has several third holes on the side wall near the simulation tube 23. The outer side wall of the open-top simulation box 1 is fixedly connected to a second air pump 5 by bolts. The model of the second air pump 5 is preferably DQE1100. The collection chambers are all connected to the input end of the second air pump 5.

[0041] In this embodiment, spotlights 231 for simulating firelight are fixedly connected to the bottom wall of the simulation tube 23 by bolts, and the spotlights 231 are electrically connected to the controller.

[0042] In this embodiment, a diaphragm 232 is bonded and fixed inside each of the simulation tubes 23. The diaphragm 232 divides each of the simulation tubes 23 into an upper chamber that communicates with the connecting box 24 and a lower chamber that contains a predetermined portion.

[0043] In this embodiment, the control system also includes a camera 6, preferably an SNC-VB770. The camera 6 is used to collect image information inside the open-top simulation box 1. The camera 6 is electrically connected to the controller, and the controller controls the speaker 3 to work according to the image information.

[0044] In this embodiment, an ultrasonic detector 4 is provided on the inner wall of the open-top simulation box 1, and the controller is electrically connected to the ultrasonic detector 4.

[0045] In this embodiment, filter screens 241 are glued and fixed at the connection points between the blower pipe 22 and the connecting box 24.

[0046] The specific implementation process is as follows: When using this device, after the user enters the device, the science popularization personnel randomly input type information into the controller, such as inputting Class A solid fire or Class B liquid fire, etc. The controller controls the speaker 3 to play the corresponding voice message to the user, such as "Class A fire ahead" or "Class B fire ahead". At the same time, the controller's heating wire, water pump, first air pump 25 and spotlight 231 work. The first air pump 25 introduces air into the blower pipe 22. After the air enters the connection box 24, it enters the simulation tube 23 and exits the simulation tube 23 through the first hole. Under the action of air pressure, the simulation tube 23 stands upright, and the airflow flows in the simulation tube, making the simulation tube... The air pressure on the inner wall of 23 decreases, causing it to oscillate under the influence of air pressure, which can simulate the flickering effect of flames to a certain extent. At the same time, the controller adjusts the speed of the air ejected from the first hole by adjusting the operating power of the first air pump according to the set fire type. When the air ejected from the first hole is too strong, it pushes the baffle 233 to flip. The change in the speed of the air ejected from the first hole causes a change in the force that pushes the baffle 233, thereby changing the angle of the baffle 233 flipping and thus changing the opening size of the first hole. The light from the spotlight 231 illuminates the simulation tube 23 to a certain extent, which can simulate the color of the flames to a certain extent.

[0047] The heating wire heats the liquid inside the coil 21, which, through heat transfer, raises the air temperature inside the blower 22, thereby raising the air temperature ejected from the first hole. At the same time, the coil 21 also raises the temperature inside the open-top simulation box 1 through heat transfer, thus simulating the temperature of a fire scene. The temperature sensor continuously collects the temperature inside the coil 21. When the temperature exceeds the set temperature, the controller stops the heating wire from working, preventing the temperature inside the open-top simulation box 1 from becoming too high and causing injury to the user.

[0048] According to the fire type announced by the speaker 3, the user selects the appropriate simulated fire extinguisher 7 and uses it to spray the particles from the simulated fire extinguisher 7 to the appropriate position in the simulated tube 23. When the simulated fire extinguisher 7 is selected correctly, the air sprayed from the first hole does not provide enough resistance to the particles, allowing them to enter the simulated tube 23 through the first hole. When the number of particles accumulated in the simulated tube 23 reaches a certain level, they block the connection between the simulated tube 23 and the connecting box 24, making it difficult for air from the connecting box 24 to enter the simulated tube 23. Under the influence of gravity, the simulated tube 23 becomes difficult to maintain its upright position and bends and collapses, thus simulating the extinguishing of the fire. At the same time, the particles entering the simulated tube 23 can, to some extent, obstruct the spotlight 231, causing the brightness of the spotlight 231 to decrease as the amount of particles entering increases, thus simulating the scenario where the flames gradually weaken as the fire extinguishing progresses.

[0049] When the simulated fire extinguisher 7 is not selected correctly, if the weight of the particles in the selected simulated fire extinguisher 7 is less than the weight of the particles in the correct simulated fire extinguisher 7, the resistance generated by the air ejected from the first hole will prevent the particles from entering the simulated tube 23. If the weight of the particles in the selected simulated fire extinguisher 7 is greater than the weight of the correct particles, the opening opened by the air ejected from the first hole will not be sufficient to allow the particles to enter.

[0050] During use, when the simulated fire extinguisher 7 fails to aim at the flame, the sprayed particles reach the surface of the connecting box 24 and block the second hole. This reduces the amount of air leaving the connecting box 24 through the second hole and increases the amount of air entering the simulation tube 23. The air sprayed through the first hole travels at a faster speed, making it more difficult for the particles to enter the simulation tube 23 through the first hole. This simulates the situation where the simulated fire extinguisher 7 is sprayed at the wrong position, making subsequent fire extinguishing work more difficult.

[0051] For example, the applicable fire extinguisher types for fire types A and B are water-type fire extinguishers and dry powder fire extinguishers, respectively. When the above fire types are input, the controller controls the first air pump 25 to work, which changes the air velocity ejected from the first hole and the angle of the baffle 233. Thus, in the case of a Class A fire, the first hole only allows particles with a weight greater than or equal to 1 and a diameter less than or equal to 1 to pass through. In the case of a Class B fire, the first hole only allows particles with a weight greater than or equal to 6 and a diameter less than or equal to 6 to pass through. The particles in the simulated fire extinguisher 7 simulating a water-type fire extinguisher have a weight of 5 and a diameter of 1, while the particles in the simulated fire extinguisher 7 simulating a dry powder fire extinguisher have a weight of 10 and a diameter of 6. When facing a Class B fire, if the user selects the correct simulated fire extinguisher 7, the particles can smoothly enter the simulated tube 23. If the user selects the simulated fire extinguisher 7 simulating a water-type fire extinguisher, although the particles can overcome the resistance of the air ejected from the first hole, their diameter is too large and will be blocked by the baffle 233, so they still cannot enter the simulated tube 23.

[0052] When the user sprays the simulated fire extinguisher 7 at the wrong position, the particles in the simulated fire extinguisher 7 will block the second hole, increasing the air velocity ejected from the first hole. This increases the weight and size of the particles that can enter through the first hole in the case of a Class A fire, making them heavier than or equal to 5 and smaller than or equal to 5. At this time, the particles in the simulated fire extinguisher 7 of the simulated water fire extinguisher can still enter the first hole, while the particle size of the simulated fire extinguisher 7 of the simulated dry powder fire extinguisher is still too large to enter the simulated tube 23.

[0053] During use, camera 6 continuously collects image information inside the open-top simulation box 1. If the simulation tube 23 does not bend or collapse within the set time, the simulated fire extinguisher 7 selected by the user is incorrect. At this time, the controller controls speaker 3 to play an audio message containing "Incorrect use of fire extinguisher" to prompt the user. When the simulated tube 23 bends and collapses in the image information in the order from high to low, the user starts extinguishing the fire from the top of the flames. The controller controls speaker 3 to play an audio message containing "Incorrect extinguishing position" to prompt the user. When the simulated tube 23 bends and collapses starting from the lower part of the flames, the user aims the simulated fire extinguisher 7 at the base of the flames. At this time, the extinguishing position is correct, and the controller controls speaker 3 to play an audio message containing "Great job, you have successfully extinguished the fire."

[0054] After use, the science popularization personnel control the second air pump 5 to work. The second air pump 5 creates negative pressure in the collection chamber, thereby attracting the particles sprayed outside the simulation tube 23 and connecting box 24 in the open-top simulation box 1, so that these particles enter the collection chamber for collection, reducing the impact of these particles on subsequent use, facilitating the reuse of particles, and reducing the use cost of this device.

[0055] The diaphragm 232 in this device prevents particles entering the simulation tube 23 from directly contacting the spotlight 231, thus avoiding the entry of particles into the spotlight 231 and causing damage to the spotlight 231, which would affect the service life of the spotlight 231. This also reduces particle loss to some extent.

[0056] This device uses an ultrasonic detector 4 to continuously collect particle concentration information inside the open-top simulation chamber during use. When the concentration exceeds a set value, the controller activates the second air pump to collect the particles, thereby preventing excessive particle concentration in the air inside the open-top simulation chamber from affecting the user's health.

[0057] This device reduces the number of particles entering the connecting box 24 and then the blower pipe 22 by using the filter screen 241, thereby reducing particle waste and lowering the operating cost of the device.

[0058] This device simulates the shape, temperature, and flickering light of flames during a fire by using a simulation tube 23, a coil 21, and a spotlight 231. It also simulates the situation where the fire extinguisher 7 is sprayed in the wrong position, making subsequent firefighting efforts more difficult. This provides users with a realistic firefighting experience while ensuring their safety. Furthermore, the device evaluates the user's choice of fire extinguisher and firefighting location during the firefighting process using a first air pump 25, a baffle 233, and a camera 6, and provides feedback to the user, thus achieving the goal of educating users about fire safety.
