[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] The following is in conjunction with the appendix Figures 1-2 The specific embodiments of this utility model will be described in further detail.

[0020] In this embodiment, through Figures 1-2 As shown, this utility model includes a control system, a gas supply system, an ignition system, a combustion air supply system, and a safety monitoring system. The gas supply system, the ignition system, the combustion air supply system, and the safety monitoring system are all electrically connected to the control system.

[0021] In this embodiment, the control system includes a PLC control board 1, and a data acquisition and output module 2 is electrically connected to the PLC control board 1.

[0023] In this embodiment, the gas supply system includes a gas source pressure transmitter 3, a gas supply pressure transmitter 4, a gas source solenoid valve 5, a gas supply electric ball valve 6, a gas supply solenoid valve 7, a gas source pressure reducing valve 8, and a gas supply pipeline. The gas supply pressure at the gas source supply end 17 is ≥0.5MPa. Liquefied petroleum gas or natural gas can be used as fuel. The gas source pressure transmitter 3, the gas supply pressure transmitter 4, the gas supply electric ball valve 6, and the gas source pressure reducing valve 8 are all electrically connected to the data acquisition and output module 2.

[0025] Among them, the gas source pressure transmitter 3 is installed at the gas source pipeline inlet and connected to the gas source supply end 17, and is used to detect the pressure of the gas source supply end 17.

[0026] The gas source pressure reducing valve 8 is connected to the gas source pressure transmitter 3 to reduce the gas source pressure;

[0027] The gas supply solenoid valve 7 is connected to the gas source pressure reducing valve 8 and is used to control the gas supply and demand.

[0028] The gas supply solenoid valve 7 is connected to the gas supply electric ball valve 6 and is used to regulate the gas flow rate.

[0029] The gas supply pressure transmitter 4 is used to detect the gas supply pressure in the gas supply pipeline.

[0030] In this embodiment, the ignition system is a high-energy igniter 9, which is electrically connected to the PLC control board 1 to generate an electric spark to ignite the gaseous fuel.

[0031] In this embodiment, the combustion air supply system mainly consists of an air compressor 10, an air tank 18, an air supply pressure transmitter 11, an air supply solenoid valve 12, an air supply electric ball valve 13, and an air supply pipeline. The air supply electric ball valve 13, the air supply solenoid valve 12, and the air compressor 10 are all electrically connected to the PLC control board 1. The air supply pressure transmitter 11 and the air supply electric ball valve 13 are electrically connected to the data acquisition and output module 2, which is used to control the air volume of combustion air supply according to the real-time flame size. The air tank 18, the air supply electric ball valve 13, the air supply solenoid valve 12, and the air compressor 10 are all installed and connected to the air supply pipeline.

[0032] The air compressor 10 is connected to the air tank 18, and the air is compressed by the air compressor 10 and then stored in the air tank 18.

[0033] The air supply pressure transmitter 11 is connected to the air storage tank 18 and is used to monitor the air pressure inside the air storage tank 18;

[0034] The air supply solenoid valve 12 is connected to the air supply pressure transmitter 11 and is used to control the air supply and shut-off at the outlet of the air storage tank 18.

[0035] The air supply electric ball valve 13 is connected to the air supply solenoid valve 12 and is used to regulate the air flow.

[0036] In this embodiment, the safety monitoring system includes a combustible gas detector 14, a flame detector 15, and an exhaust fan 16. The combustible gas detector 14 and the flame detector 15 are electrically connected to the data acquisition and output module 2. The combustible gas detector 14, the flame detector 15, and the exhaust fan 16 are all electrically connected to the PLC control board 1, which is used to monitor combustible gas leaks and take measures to ensure personnel safety.

[0037] The data acquisition terminals of combustible gas detector 14, flame detector 15, gas supply electric ball valve 6, air supply electric ball valve 13 and gas source pressure reducing valve 8 are all connected to the terminals of data acquisition output module 2.

[0038] The control terminals of combustible gas detector 14, flame detector 15, exhaust fan 16, gas supply electric ball valve 6, gas source solenoid valve 5, gas supply solenoid valve 7, gas source pressure reducing valve 8, high-energy igniter 9, air compressor 10, air supply solenoid valve 12, and air supply electric ball valve 13 are all connected to the wiring terminals of PLC control board 1. Figure 1 As shown in the figure, the repeated labels are the data acquisition terminal and the control terminal of this structure, with the control terminal on the left and the data acquisition terminal on the right.

[0039] Combustible gas detector 14 is used to detect combustible gas, flame detector 15 is used to detect flame status, and feeds back combustible gas detection information and flame status information to data acquisition and output module 2, so that data acquisition and analysis are performed and sent to PLC control board 1. When a situation occurs, PLC control board 1 controls exhaust fan 16 to run and exhaust combustible gas.

[0040] When the combustible gas detector 14 detects a combustible gas leak and the flame detector 15 determines that the ignition conditions are not met, the PLC control board 1 will receive the signal from the data acquisition and output module 2, control the gas supply system to stop supplying gas, and control the exhaust fan 16 to exhaust air, thereby reducing the occurrence of dangerous accidents and ensuring personnel safety.

[0041] When ignition is in operation, the PLC control board 1 collects the pressure from the gas source pressure transmitter 3 and the pressure reducing valve adjusted by the gas supply pressure transmitter 4. When the gas source pressure is high, it is reduced by the gas source pressure reducing valve 8 to a pressure that is easy to ignite.

[0042] PLC control board 1 controls the opening and closing state of gas supply electric ball valve 6. The opening and closing angle of gas supply electric ball valve 6 is adjustable. Different opening and closing angles result in different gas flow rates. The larger the opening and closing angle, the greater the flow rate.

[0043] When the pressure decreases to a level where it is easy to ignite, the PLC control board 1 controls the high-energy igniter 9 to work, generating an electric spark to ignite the gas. At this time, the flame produced by combustion is the size of a gas stove, with a flame height of 10-20cm.

[0044] When the operator selects the flame size, the adjustment ratio is 0-100%, controlling the pressure reduction of the gas source pressure reducing valve 8 and the opening angle of the gas supply electric ball valve 6. The greater the gas supply pressure and the larger the opening angle of the gas supply electric ball valve 6, the greater the flow rate, and the larger the flame will gradually become. As the flame grows larger, the oxygen around the flame is rapidly consumed. At this time, the system will control the operation of the combustion air supply system's air supply solenoid valve 12 and air supply electric ball valve 13 according to the gas supply pressure. The larger the flame, the more air is supplied, and the larger the fire becomes. At this time, the fire meets the training needs of fire and rescue personnel.

[0045] When the system is in operation, if a gas leak occurs (combustible gas detector 14 activates) or ignition fails (flame detector 15 activates), the gas supply continues, increasing the concentration of combustible gas in the space. When combustible gas detector 14 detects combustible gas, it issues an alarm signal. At this time, the system can control all actuators to stop working and quickly activate exhaust fan 16 to reduce the concentration of combustible gas in the space, ensuring the safety of training personnel.

[0046] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
