The mouth of the gas cylinder 7 provided with the inert gas is passed into the detection cabinet 11 through a gas transmission device, so that the inert gas in the gas cylinder 7 can quickly rush into the detection cabinet 11, thereby quickly extinguishing the combustibles in the detection cabinet 11 and playing a role of flame retardant protection.

[0030] The detection cabinet 11 is provided with a horizontal support platform, a clamp arranged on the support platform, and an ignition device and a control part arranged above the support plate 19. The clamp is used to clamp the material to be detected. The ignition device is connected to the bottle mouth of the gas cylinder 7 provided with combustible gas through the gas transmission device, so that the combustible gas in the gas cylinder 7 can be transported to the ignition device for combustion;

[0031] The control part includes a control cabinet 3 arranged at the bottom of the support platform 1, and a controller and an igniter are arranged in the control cabinet 3. The controller and the igniter are electrically connected, and the controller is a host, a PLC logic controller or a control mainboard;

[0032] An operating table 14 is also provided at one end of the supporting platform 1 away from the gas cylinder 7. A display and operating buttons are provided on the surface of the operating table 14. The display and operating buttons are electrically connected to the controller respectively; the operating buttons include a gas flow adjustment button, an emergency fire extinguishing button, a start / stop button of the entire device, and an ignition button, etc.;

[0033] Among them, Figure 3 As shown, the ignition device includes a burner 21, which is located above the support plate 19 and is installed at the bottom of the support tube 32. The surrounding side of the support tube 32 is also provided with a gas pipeline 16 and an insulating sleeve 22 parallel thereto. The insulating sleeve 22 is made of insulating materials such as a ceramic tube or a heat-resistant rubber tube. An ignition needle 20 is arranged in the insulating sleeve 22. The igniter is electrically connected to the ignition needle 20. The burner 21 and the bottom of the ignition needle 20 are both located at the burner 21.

[0034] The tops of the support tube 32, the insulating sleeve 22, and the gas pipeline 16 are all arranged on the first bracket 15, and the end of the first bracket 15 away from the cabinet door 13 is fixed to the inner wall of the control cabinet 3, and the bottom of the support tube 32 is connected to the insulating sleeve 22 and the gas pipeline 16 respectively through the second bracket 30, so that the support tube 32, the insulating sleeve 22, and the gas pipeline 16 can be supported and connected as a whole. In this solution, the first bracket 15 and the second bracket 30 are provided with insulating pads at the contact positions with the support tube 32 and the gas pipeline 16, so as to avoid the mutual transmission of electric sparks;

When the electric control valve 8 connected to the combustible gas is opened, the ignition needle 20 also ignites at the same time. When the combustible gas is ejected from the burner 21, it can be ignited, and the flame will spray and burn toward the detection object in the fixture. When the height of the combustible flame exceeds the preset value or other dangerous situations occur, the electric control valve 8 connected to the inert gas can be controlled to open, so that the inert gas can be directly sprayed on the burning part of the detection object, which can quickly extinguish the fire.

[0037] Further, such as Figure 3 As shown, an infrared temperature sensor 31 is also provided on the top of the control cabinet 3, and the irradiation direction of the infrared temperature sensor 31 is toward the burner 21, so that the temperature of the flame can be directly detected;

A pipe can be connected to the outlet of the exhaust fan 12 to pass the smoke into the purification equipment for purification. When a dangerous situation occurs, that is, the moment the inert gas is ejected, the electric control valves on the ports of the air inlet fan 23 and the exhaust fan 12 are also closed to prevent the inert gas from leaking out.

[0043] Based on the above embodiment, further optimization can be performed, where the gas flow sensor 9, the electric control valve 8 connection, and the pressure gauge are all installed on the mounting frame 10, thereby avoiding the scattered placement of various components.
