Description

Technical Field

[0001] The invention belongs to the field of fire training equipment, and in particular relates to a simulated explosion device for fire training. Background Art

[0002] In the era of industrialization, safety has become a necessary issue. Especially in situations involving dangerous goods, higher requirements are placed on the training and skills of firefighters. Simulated explosions can train firefighters' psychological qualities and methods of dealing with emergencies, experience the direct feeling of explosions caused by fires or hazardous chemical sites, and strengthen targeted training to deal with real situations, which has become a subject that firefighters urgently need to train.

[0003] At present, various fields are developing simulation training equipment, for example, explosion shock simulation devices suitable for military training needs, which are suitable for military training but not for firefighting needs. This is because firefighting simulation explosions must restore the real degree of simulated hazardous chemical leakage explosions as much as possible, such as the high temperature and visual impact generated during the explosion, and there must not be excessive shock waves that injure firefighters.

[0004] For fire explosion training, there is a related technical solution that selects a large number of detonators to explode to simulate the fire explosion scene. This solution is too expensive, requires professional personnel to operate, and has a relative risk factor.

[0005] Therefore, it is necessary to propose a simulated explosion device for fire training to solve the shortcomings in existing fire training. Summary of the invention

[0006] In order to solve the above technical problems, an embodiment of the present invention provides a simulated explosion device for firefighting training to solve the problems raised by the prior art.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0041] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0042] The structure diagram of the simulated explosion device for firefighting training described in the embodiment of the present application is as follows Figure 1 The names corresponding to the numbers in the figure are as follows:

[0043] 1. Ignition control box; 2. Small oil tank; 3. Oil storage pipeline; 4. Oil pipeline solenoid valve; 5. Air cannon; 6. Air compressor; 7. Oil inlet booster pump; 8. Large oil tank; 9. Gas tank; 10. Gas pipeline solenoid valve; 11. Ignition burner; 12. Detonator disk.

[0044] like Figure 1 As shown in FIG. 1 , the air compressor 6 is connected to the air cannon 5 through a pipeline, and the air cannon 5 is connected to the detonating disk 12 through the oil storage pipeline 3 via the small oil tank 2, wherein the small oil tank 2 is placed above the oil storage pipeline 3.

[0045] The large oil tank 8 is connected to the oil inlet booster pump 7 and the small oil tank 2 through pipelines, wherein an oil pipeline solenoid valve 4 is provided on the pipeline connected to the small oil tank 2 .

[0046] The gas tank 9 is connected to the ignition control box 1 and the detonator 12 through pipelines. The gas tank 9 reaches the detonator 12 through the gas pipeline solenoid valve 10, which is the main fire path; the gas tank 9 pipeline directly reaches the inside of the ignition control box 1, which is the pilot fire path; the ignition burner 11 is inserted from the central position inside the ignition control box 1 to the detonator 12, which is used to ignite the detonator 12.

[0047] The oil pipeline solenoid valve 4, the gas pipeline solenoid valve 10, the air cannon 5, the air compressor 6, the liquid level gauge on the small oil tank 2 and the ignition control box 1 are electrically connected to the PLC (Programmable Logic Controller) respectively and are automatically controlled by the PLC.

[0048] Among them, the internal structure diagram of the ignition control box 1 is as follows Figure 2 The ignition control box 1 comprises: a variable frequency fan 1a; an ignition high voltage package 1b; and a solenoid valve 1c.

[0049] The pipeline from the gas tank 9 in the ignition control box 1 reaches the gas path interface of the ignition burner 11 through the solenoid valve 1c and the metal hose. The variable frequency fan 1a is connected to the air supply interface of the ignition burner 11 to supply oxygen to the pipeline of the ignition burner 11. The ignition high-voltage package 1b is electrically connected to the ignition burner 11 to emit electronic pulses to it. Among them, the controller of the ignition high-voltage package 1b and the inverter of the variable frequency fan 1a are electrically connected to the PLC respectively. The ignition high-voltage package 1b is electrically connected to the controller, and the variable frequency fan 1a is electrically connected to the inverter.

[0050] The overall process of using PLC to control the simulated explosion device for fire training is as follows:

[0051] Control the ignition process: PLC first determines whether the pressure of the air compressor 6 has reached the set pressure, and whether the liquid level of the liquid level gauge on the small oil tank 2 has reached the set liquid level. The set pressure is generally 8 kg. The higher the pressure, the better the explosion effect. The liquid in the small oil tank 2 is a mixture of diesel and gasoline. If it has not reached the set liquid level, the PLC will control the opening of the oil pipeline solenoid valve 4 and the oil inlet booster pump 7 to send the diesel and gasoline mixture in the large oil tank 8 to the small oil tank 2, and its liquid level will reach the high position of the air cannon 5 to the detonator disk 12 pipeline, that is, the low position of the oil storage pipeline 3 is filled with diesel and gasoline mixture, so that it reaches the set liquid level. If the set pressure is not reached, wait for the air compressor 6 to charge until the set pressure is reached. After the above settings are met, the PLC sends a completion instruction and the display light comes on. At this time, the solenoid valve 1c in the ignition control box 1 will be opened by starting with the PLC, and the combustible gas in the gas tank 9 will be transported to the ignition burner 11 through the pipeline. At this time, the ignition high-voltage package 1b will emit an electronic pulse to ignite the combustible gas at the ignition burner 11. The ion probe in the ignition burner 11 will be used to determine whether the ignition fire is successfully ignited, and its information will be fed back to the PLC. After the ignition fire is successfully ignited, the main fire circuit solenoid valve, i.e., the gas circuit pipeline solenoid valve 10, will be started to send the combustible gas to the detonation disk 12, and the flame in the detonation disk 12, i.e., the main fire, will be ignited through the ignition circuit, i.e., the flame at the ignition burner 11.

[0052] Detonation process: After the main fire is ignited, the ion probe in the detonation disk 12 determines whether it is successful or not, and feeds back its success signal to the PLC again. The ion probe uses the ionization phenomenon to detect the ion concentration in the flame to determine whether the flame is burning. After confirming that the main fire is ignited, the PLC controls the nozzle in the air cannon 5 to open, and the high-pressure air impacts the diesel and gasoline mixture in the oil storage pipeline 3 at a very high speed, generating a huge impact force, pushing it out of the detonation disk 12, and the flame is instantly ignited through the main fire path, forming a huge fireball with thick smoke.

[0053] If it is determined that the flame of the pilot path fails to ignite, the PLC will quickly re-issue the re-ignition command after receiving feedback information until the ignition is successful or the ignition is cancelled. The ion probe uses the ionization phenomenon.

[0054] Diesel and gasoline mixtures produce thick smoke because diesel is not as easy to ignite as gasoline, so the flammability of gasoline is combined with the thick smoke of diesel to form an explosion effect. When the diesel and gasoline mixture is sprayed out, it is a divergent spray, almost forming a spray ball, and after ignition, it will form a huge high-temperature fireball. And because the diesel and gasoline mixture is quickly sprayed out, it will quickly mix with the air. After ignition, the gas expands rapidly, the air temperature rises sharply, causing air vibration to produce an explosion sound.

[0055] The explosion of the diesel and gasoline mixture does not have a shock wave as large as that of a detonator explosion, and because the air is sprayed upward through the air cannon 5, the shock wave formed by the explosion of the diesel and gasoline mixture is biased upward and away from the people on the ground.

[0056] After each explosion is successfully ignited, the diesel and gasoline mixture in the small fuel tank 2 will automatically fill to the set liquid level, that is, the high position of the pipeline from the air cannon 5 to the detonator disk 12, waiting for the next explosion to start.

[0057] The PLC described in the embodiment of the present application is set in a control cabinet, which is placed away from the fire training simulation device to ensure the safety of the PLC, so it is not drawn in the figure. The PLC is electrically connected to each component of the device. Tablet computers and other operating devices can be remotely controlled by wirelessly connecting to the PLC to achieve convenience and safety.

[0058] The simulated explosion device for firefighting training described in the embodiment of the present application does not require professional technicians, is easy to operate, simple, fast, and safe, and ensures the real effect of training.

[0059] In summary, the simulated explosion device for fire training described in the embodiment of the present application can simulate the explosion scene of a real fire scene in a safe environment, so that firefighters can conduct emergency training and improve their ability to deal with emergencies. The device has high safety and reliability and strong adaptability, can be applied to different fire training bases and training scenes, and has strong promotion and application value.
