[0022] When in use, first refer to the layout of the domestic mainstream aircraft to fix the rotary inductive switch 10 and the control box 9 to the corresponding position, where the control box 9 has a button to control the automatic opening and closing of the cargo door, and the rotary inductive switch 10 has a button to control the opening and closing of the cargo door. When the training begins, the firefighter first enters the cabin 1, then powers on the control box 9, and further presses the door opening button on the control box 9. At this time, the hydraulic station 8 starts to work, pumping the hydraulic oil in the oil tank into the hydraulic cylinder 5. At this time, the hydraulic cylinder 5 starts to elongate, and the cargo door is opened. When the door opening operation is completed, the power is further turned off, and the hydraulic cylinder 5 is locked by relying on the oil pipe pressure, so that the cargo door is fixed at a certain position. When closing, the control box 9 also needs to be powered on, and the door closing button is pressed again. At this time, the hydraulic station 8 starts to work, pumping the hydraulic oil in the hydraulic cylinder 5 back to the oil tank. At this time, the hydraulic cylinder 5 starts to retract, and the cargo door is closed. The operation of simulating the emergency manual mechanical opening of the cargo door is installed at the corresponding position of the real airplane manual mechanical opening. When the manual mode switch is opened, the system will change the automatic control mode of the control box 9 to manual control mode. The rotary inductive switch 10 connects the hydraulic station 8 through electrical signals. When the firefighter rotates the handle at this point, the electrical signal will be sent to the hydraulic station 8 to work, pumping the hydraulic oil in the oil tank into the hydraulic cylinder 5. At this time, the hydraulic cylinder 5 starts to elongate, and the cargo door is opened. When not rotating, no electrical signal will be transmitted, and the hydraulic cylinder 5 is locked by relying on the oil pipe pressure, so that the cargo door is fixed at a certain position. When the firefighter rotates the handle in the opposite direction, the electrical signal will be sent to the hydraulic station 8 to work. At this time, the hydraulic station 8 starts to work, pumping the hydraulic oil in the hydraulic cylinder 5 back to the oil tank. At this time, the hydraulic cylinder 5 starts to retract, and the cargo door is closed. The principle is to use the rotary inductive switch 10 signal to control the hydraulic system to work, so as to simulate the real airplane through the handle to drive the connecting rod and gear to drive the cargo door movement, that is, to restore and train this handle operation step by means of electrical signal instead of mechanical transmission. When simulating the real fire training, the cabin 1 needs to be placed in a container. The container is placed with flammable materials, and then the container is placed in the cabin 1. At this time, high-temperature gas flow or even flame will be generated towards the door. However, since the hydraulic cylinder 5 of the cargo door opening system is protected in the U-shaped frame 402, and the space between the outer shell and the U-shaped frame 402 is filled with heat insulation material 6, the high-temperature gas flow and flame can be avoided from directly roasting the hydraulic cylinder 5, so as to protect the hydraulic cylinder 5 from being damaged by high temperature.

[0023] In summary, the aircraft fire rescue real fire training system cargo door opening system can control the automatic extension and retraction of the hydraulic cylinder 5 through the control box 9 cooperating with the hydraulic station 8 to realize the automatic opening and closing of the cabin door, and can manually control the extension and retraction of the hydraulic cylinder 5 through the rotary induction switch 10 cooperating with the hydraulic station 8 to realize the manual control of the opening and closing of the cabin door, thereby simulating the training course of automatically and manually opening the cabin door after the aircraft cargo compartment catches fire. The hydraulic cylinder 5 is installed in the U-shaped frame 402 and there is a certain gap between them, the heat insulation material 6 with certain viscosity and elasticity is filled into the gap to wrap the shell of the hydraulic cylinder 5, the heat insulation material 6 can insulate heat and does not affect the small range swing of the hydraulic cylinder 5, thereby realizing the effect of greatly avoiding the damage of the hydraulic cylinder 5 due to being grilled.

[0024] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
