[0002] In the real fire simulation training of firefighters, in order to simulate the complex combustible composition and combustion forms of different combustibles in real fire scenes, real fire simulation training facilities generally need to be equipped with gas, fuel oil and other combustion media as supporting fuels. In some special real fire simulations, some real combustibles need to be placed. For example, in the simulation facilities that simulate the two extreme combustion phenomena of flashover and backdraft, it is necessary to place real complex combustibles such as firewood, furniture, and bedding to reproduce the real combustion effect, so as to better carry out fire rescue training and practical teaching.

[0003] All of these combustion media need to be ignited by an igniter to achieve a real fire combustion effect. In order to ensure that a continuous and uninterrupted open flame source can be provided when firefighters conduct water shooting training on fire points, and to ensure the continuity and repeatability of the real fire combustion effect, a special ignition device is required to provide a long open flame to meet the needs of simulated real fire training.

[0004] Therefore, it is an inevitable requirement to provide firefighters with a safe and effective ignition device to replace manual ignition for real fire simulation training. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a technical solution: an ignition device for firefighter real fire simulation training facilities, including a high-energy ignition gun, an oil supply pipe and a controller.

[0007] The oil supply pipe is located at one side of the high-energy ignition gun, and an atomizing nozzle is provided at the end of the oil supply pipe that is the same as the ignition end of the high-energy ignition gun. The high-energy ignition gun generates high-voltage electric sparks, and the atomizing nozzle sprays atomized diesel.

[0011] Furthermore, the bending angle of the curved pipe is 45 degrees.

[0012] Furthermore, the oil supply pipe and one end of the high-energy ignition gun are exposed from the sealing plate.

[0021] 5. Use explosion-proof fans to continuously supply oxygen to the combustion chamber to ensure continuous combustion of fuel in the combustion chamber, and continuously provide a stable and ever-burning fire source for the combustion point, which has better stability;

[0022] 6. The fire outlet of the combustion chamber faces downward, which can effectively prevent firefighters from extinguishing the fire source when spraying water on the fire point, ensuring a continuous open flame source, and the structural design is more reasonable;

[0023] 7. The ignition device has no special installation requirements and can meet the ignition needs of various combustion points. The installation position and external dimensions can be customized according to the installation position of the actual combustion point, which has a wider range of applications;

Obviously, the described embodiments are only part of the embodiments of the present utility model, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present utility model.

[0032] It should be noted that all directional indications such as up, down, left, right, front, back... in the embodiments of the utility model are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0033] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0034] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0035] The utility model will now be further described in conjunction with the accompanying drawings.

[0036] Combined with Figure 1-5 The seamless steel pipe 5, the elbow 10, the tee pipe 4, and the sealing plate 9 together form an open combustion chamber, and the ends of the oil supply pipe 2 and the high-energy ignition gun 1 extend into the combustion chamber, and the combustion chamber serves as a long-fire combustion area.

[0037] The seamless steel pipe 5, the three-way pipe 4, and the sealing plate 9 together form a wind bin, which is provided with a fresh air source by an explosion-proof fan, and the fresh air is transported to the wind bin by the air duct connecting pipe 8. The fresh air enters the combustion bin through the vent hole 7 on the positioning plate 6 to supply oxygen to the combustion bin.

[0038] The fuel supply pipe 2 provides continuous diesel as a combustion medium for the combustion chamber. The atomizing nozzle 3 atomizes the diesel, making it easier to ignite and enhancing the combustion effect.

[0039] The high-energy ignition gun 1 generates high-voltage electric sparks to ignite the atomized diesel to achieve combustion of the diesel.

[0040] The controller mainly includes a PLC control unit and a signal transmission cable: it provides automatic control conditions for the ignition device, controls the on and off of the oil supply pipeline and the solenoid valve, monitors the working status of each device of the ignition device, and carries the functions of safety monitoring and automatic alarm. Temperature sensor: connected to the PLC control unit to monitor the working temperature of the ignition device. Flame detector: connected to the PLC control unit to accurately judge the combustion flame in the combustion chamber, and has the function of automatic material cutting when the flame is turned off.

[0041] The front-end fuel supply pipeline and solenoid valve deliver diesel to the ignition device. The solenoid valve is connected to the PLC control unit to control the pipeline on and off. The pressure sensor monitors the pressure of the fuel supply pipeline of the ignition device.

[0042] Specific operation process: When firefighters need to use an ignition device for real fire simulation training, the PLC control unit first opens the solenoid valve of the oil supply pipeline, and the oil supply pipeline begins to transport diesel to the ignition device. When the pressure sensor detects that the pressure value of the oil supply pipeline of the ignition device section has reached the design value and has been stable for 3 seconds, the high-energy ignition gun 1 starts working and continuously generates high-voltage electric sparks to ignite the diesel atomized by the atomizing nozzle in the combustion chamber. When the flame detector detects that there is an open flame in the combustion chamber, the high-energy ignition gun stops working and the explosion-proof fan starts working to continuously provide fresh air for oxygen supply to the combustion chamber. At the same time, the diesel fire in the combustion chamber is continuously blown out of the combustion chamber to ignite other fuels configured at the combustion point of the training facility, thereby achieving the combustion effect of real fire simulation.

[0043] When the training is completed, the PLC control unit executes a one-button stop function and automatically cuts off the fire and material. After the fuel fire is extinguished, the explosion-proof fan continues to work and continuously supplies air to the combustion chamber for 20 seconds to ensure that there is no residual oil accumulation in the combustion chamber and to ensure the normal service life of the ignition device.

[0044] The utility model and its implementation methods are described, and such description is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
