[0038] In the embodiment of the present application, the ignition simulation component 31 and the smoke simulation component 32 can simulate the state of the tire 2 rubber catching fire and emitting smoke, and truly restore the state of the aircraft landing gear catching fire, which is convenient for airport firefighters to conduct simulation training, thereby greatly improving the training effect of airport firefighters in quickly handling aircraft landing gear fires, and achieving the training purpose of training airport firefighters to quickly handle aircraft landing gear fires.

[0039] In one possible embodiment, Figure 3 is a schematic diagram of an ignition simulation component 31 provided in an embodiment of the present application, Figure 4 is a top cross-sectional view of the ignition simulation assembly 31 provided in an embodiment of the present application, Figure 2 , Figure 3 and Figure 4 As shown, the ignition simulation component 31 includes a landing gear fire pool 311 , a fire pool gas pipeline 312 , a flame head 313 and an ignition needle 314 .

[0040] The landing gear fire pool 311 is arranged on the inner side of the tire 2 rim, and support frames 11 are respectively arranged on both sides of the bottom of the landing gear fire pool 311 . The support frames 11 can be placed on the side wall of the tire 2 and support the landing gear fire pool 311 .

[0041] The support frame 11 can be set as an angle steel or other steel plate with a supporting function. The support frame 11 can be fixed on the landing gear fire pool 311 by bolts, and can also be directly welded to the landing gear fire pool 311.

[0042] The fire pit gas pipeline 312 is installed on the inner wall of the landing gear fire pit 311, and one end of the fire pit gas pipeline 312 is connected to the flame head 313. In the embodiment of the present application, four flame heads 313 are provided, and the flame heads 313 are parallelly distributed inside the landing gear fire pit 311. The other end of the fire pit gas pipeline 312 is used to communicate with the natural gas pipeline. In order to facilitate the connection between the fire pit gas pipeline 312 and the natural gas pipeline, a pipeline connector 319 is provided at one end of the fire pit gas pipeline 312 extending out of the landing gear fire pit 311. One end of the pipeline connector 319 is connected to the fire pit gas pipeline 312, and the other end is used to communicate with the natural gas pipeline.

[0043] The base of the ignition needle 314 is fixed on the landing gear fire pool 311 by bolts, and the ignition needle 314 is close to the flame head 313. When the flame head 313 has natural gas spraying, the ignition needle 314 is adjusted, and the ignition needle 314 can ignite the natural gas, so that the flame head 313 sprays fire and burns, simulating the state of the tire 2 rubber catching fire.

[0044] In the embodiment of the present application, by arranging a flame head 313 in the landing gear fire pool 311, under the action of the ignition needle 314, the burning flame generated by the aircraft landing gear in a fire state can be simulated, so that firefighters can deal with the fire of the aircraft landing gear, thereby achieving the purpose of training firefighters.

[0045] In a possible embodiment, Figure 2 , Figure 3 and Figure 4 As shown, the smoke simulation component 32 includes a smoke machine 321 and a smoke delivery pipe 322 arranged on the smoke machine 321 .

[0046] The smoke machine 321 can be arranged beside the landing gear 1 or on the landing gear 1 .

[0047] One end of the smoke delivery pipe 322 is connected to the smoke outlet of the smoke machine 321, and the other end is connected to the inside of the landing gear fire pit 311. Specifically, the end of the smoke delivery pipe 322 close to the landing gear fire pit 311 can be fixed to the bottom of the landing gear fire pit 311 by bolts. By adjusting the smoke machine 321, the smoke machine 321 can deliver smoke into the landing gear fire pit 311 through the smoke delivery pipe 322, so that the landing gear fire pit 311 simulates the state of burning and generating smoke.

[0048] In the embodiment of the present application, by providing a smoke simulation component 32, it is convenient to simulate the smoke generated by the aircraft landing gear in a fire state, so that firefighters can handle the fire of the aircraft landing gear, thereby achieving the purpose of training firefighters.

[0049] In a possible embodiment, Figure 2 and Figure 3 As shown, a control component is also included, which includes a first sensor 315, a second sensor 316, a controller, and a solenoid valve arranged on the natural gas pipeline.

[0050] The first input end of the controller is connected to the output end of the first sensor 315, and the first sensor 315 is used to detect the flame temperature of the flame head 313. The first control end of the controller is connected to the control end of the smoke machine 321, the second control end of the controller is connected to the solenoid valve, and the second input end of the controller is connected to the output end of the second sensor 316.

[0051] The controller may be configured as a microcontroller or a programmable logic controller, etc., and the controller is not shown in this embodiment.

[0052] The first sensor 315 may be configured as a temperature sensor, and the second sensor 316 may be configured as a water sensor, for example, a resistive water immersion sensor or an optical water immersion sensor that senses whether there is water.

[0053] The solenoid valve can be configured as a switch solenoid valve, and the solenoid valve in this embodiment is shown as an example.

[0054] When the flame temperature detected by the first sensor 315 reaches a predetermined temperature value, the controller controls the smoke machine 321 to work, and the smoke machine 321 sprays smoke. When the flame temperature detected by the first sensor 315 reaches a set lower limit temperature, the controller controls the solenoid valve to shut off, so that the natural gas pipeline no longer supplies natural gas, thereby making the flame spray head 313 no longer spray fire.

[0055] When the second sensor 316 detects that there is water on the wheel rim of the tire 2, the controller controls the smoke machine 321 to stop working. When the second sensor 316 detects that there is water, the controller controls the smoke machine 321 to be turned off, so that the smoke machine 321 no longer emits smoke.

[0056] In specific implementation, the controller controls the electromagnetic valve to open, so that the natural gas pipeline provides natural gas to the flame head 313, and ignition is completed under the action of the ignition needle 314. The flame temperature can be detected by the first sensor 315. When the detected temperature reaches a predetermined temperature value, the controller controls the smoke machine 321 to start working, and the smoke is ejected through the smoke delivery pipe 322, thereby completing the ignition of the landing gear fire pool 311.

[0057] When the trainer uses the fire hose to put out the fire, the water lowers the temperature of the fire. The temperature of the flame can be detected by the first sensor 315. When the temperature detected by the first sensor 315 reaches the lower limit set temperature, the controller controls the solenoid valve to close, shuts off the natural gas pipeline, and completes the fire extinguishing.

[0058] When the second sensor 316 detects the presence of water, the second sensor 316 is turned on or the resistance value changes, and the controller controls the smoke machine 321 to be turned off, so that the smoke machine 321 no longer emits smoke, thereby completing the fire extinguishing training.

[0059] In one possible embodiment, Figure 5 3 is a side cross-sectional view of an ignition simulation assembly 31 provided in an embodiment of the present application, wherein a smoke exhaust plate 317 is provided in the landing gear fire pool 311, and the smoke exhaust plate 317 is provided in the middle of the landing gear fire pool 311, and the landing gear fire pool 311 can be divided into two parts, the upper and lower parts, and the smoke exhaust plate 317 is located at the bottom of the flame head 313. The smoke exhaust plate 317 can be integrally connected with the landing gear fire pool 311, and can also be fixed to the landing gear fire pool 311 by bolts.

[0060] In order to facilitate the exhaust of smoke at the bottom, a plurality of smoke holes 3171 are provided on the smoke exhaust plate 317. The smoke holes 3171 can be configured to be circular, square, or triangular, etc., and the arrangement of the smoke holes 3171 can be an array arrangement.

[0061] In a possible embodiment, Figure 4 and Figure 5 As shown, a plurality of fireproof bricks 318 are arranged on the smoke exhaust plate 317 .

[0062] The fireproof bricks 318 can be placed at positions corresponding to the flame spray heads 313 in the landing gear fire pool 311 , or can be placed on both sides of the landing gear fire pool 311 parallel to the flame spray heads 313 .

[0063] In the embodiment of the present application, by placing fireproof bricks 318 in the landing gear fire pool 311, the flame ejected from the flamethrower head 313 can be blocked from directly damaging the inner wall of the landing gear fire pool 311, the conduction of heat can be alleviated, the landing gear fire pool 311 is not damaged by heat, and the performance of the landing gear fire pool 311 is maintained; at the same time, the fireproof bricks 318 protect the flamethrower head 313 and reduce the damage caused by excessive heat of the flamethrower head 313; in addition, the fireproof bricks 318 can also have a certain waterproof effect, reducing the direct spraying of fire water onto the landing gear fire pool 311 during training.

[0064] In one possible embodiment, Figure 6 31 is a schematic diagram of a landing gear fire pit 311 provided in an embodiment of the present application. In order to improve the stability of the fire brick 318 placed on the smoke exhaust plate 317, a baffle 3172 is provided on the smoke exhaust plate 317, and the fire brick 318 can be accommodated between the baffle 3172 and the landing gear fire pit 311. The baffle 3172 and the smoke exhaust plate 317 can be connected integrally or detachably.

[0065] The working principle of the utility model is given below:

[0066] In preparation before ignition, firefighters use a special nozzle for a fire hydrant to spray water to cool down the landing gear fire pool 311. The second sensor 316 senses the presence of water, and the controller controls the smoke machine 321 to be turned off, so that the smoke machine 321 no longer emits smoke.

[0067] During ignition, the controller controls the solenoid valve to open, allowing natural gas to enter each flame head 313 through the fire pool gas pipeline 312, and adjusts the ignition needle 314. Under the action of the ignition needle 314, the flame head 313 sprays fire and burns, completing the ignition.

[0068] When the flame temperature of the flame head 313 detected by the first sensor 315 rises to a predetermined temperature value, ignition is completed, and the controller controls the smoke machine 321 to start emitting smoke, and the smoke is ejected through the smoke conveying pipe 322, so that the landing gear fire pool 311 emits smoke while emitting fire.

[0069] After the ignition is completed, firefighting is carried out. Firefighters use a special fire hydrant to spray water on the fire point. The flame sprayed by the flame head 313 begins to drop in temperature when it encounters water. When the temperature detected by the first sensor 315 reaches the lower limit set temperature, the controller controls the solenoid valve pipe section so that the natural gas pipeline no longer provides natural gas, completing the fire extinguishing operation. At the same time, when the second sensor 316 detects the presence of water, the controller controls the smoke machine 321 to turn off, so that the smoke machine 321 no longer emits smoke, completing the fire extinguishing training.

[0070] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
