Body 1 then starts hydraulic cylinder 3 so that car body 1 is moved to right above point of origin；
When hydraulic cylinder output shaft 4 moves downward, hydraulic cylinder output shaft 4 drives casing 5 to move downward together, presses resetting
Under the elastic force effect of spring 7, compression bar 18 is driven to move downward together, compression bar 18 pushes down on flash absorber 16 in turn, so that going out
Fire cover 16 declines out of cavity 2, and when flash absorber 16, which is dropped to, to offset with ground, hydraulic cylinder 3 continues to drive flash absorber 16 downward
Movement, at this time reseting pressuring spring 7 by hydraulic cylinder output shaft 4 pressure and compress, the elastic force of reset spring is applied on compression bar 18,
So that flash absorber 16 is pressed on ground by compression bar 18, so that heat resistant rubber circle 17 is adjacent to ground, so that fire extinguishing
An enclosure space is surrounded between cover 16 and ground, comburant is surrounded in the enclosed space by flash absorber 16, blocks extraneous oxygen
Into the enclosure space, so that combustion reaction can not continue to occur, simultaneously because flash absorber 16 offsets and static with bottom surface,
Therefore compression bar 18 also remain stationary with respect to ground, and hydraulic cylinder 3 continue driving under, casing 5 continues to move downward so that press
Bar 18 slides in casing 5, generates relative motion between casing 5 and flash absorber 16, so that casing 5 and jet cylinder barrel 14 and air-breathing
Generate relative motion between cylinder barrel 15, therefore left drive rod 10 and right drive rod 11 are respectively between left lead screw 12 and right lead screw 13
Relative motion is generated, so that the relatively left lead screw 12 of left drive rod 10 and right drive rod 11 and right lead screw 13 move downward, and then is made
Left lead screw 12 and right lead screw 13 rotate, simultaneously because the thread rotary orientation of left lead screw 12 and right lead screw 13 is on the contrary, therefore left lead screw
12 and right lead screw 13 turns on the contrary, left lead screw 12 drives jet piston plate 23 to move downward, while the extension rod 26 of lead screw lower end
Thread plate 30 is driven to rotate, the rotation of thread plate 30 drives the second air jet pipe 29 to move downward, so that the second air jet pipe 29
Skidded off out of first air jet pipe 27 under, at the same the carbon dioxide in jet cylinder barrel 14 by the pushing of jet piston plate 23 and it is right
Sheet rubber 32 generates pushing, so that sheet rubber 32 is open, so that carbon dioxide is ejected to flash absorber from fumarole 31
In 16；
Meanwhile the rotation of right lead screw 13 drives air-breathing piston plate 19 to move upwards, so that negative pressure is generated in air-breathing cylinder barrel 15,
So that the gas in flash absorber 16 is inhaled into air-breathing cylinder barrel 15, simultaneously because carbon dioxide is sprayed out of second air jet pipe 29
Out, and after the second air jet pipe 29 stretches out the first air jet pipe 27, compared to 20 second air jet pipe of vacuum noz(zle), 29 lower end closer to ground,
Therefore the carbon dioxide sprayed is distributed in the space on ground, simultaneously because molecular weight of carbon dioxide is greater than oxygen, therefore
Carbon dioxide pushes oxygen to the space far from ground, therefore vacuum noz(zle) 20 sucks oxygen in air-breathing cylinder barrel 15, so that
Amount of oxygen in flash absorber 16 is reduced, and amount of carbon dioxide increases, and then plays the effect for preventing flame from burning away.
After fray-out of flame, hydraulic cylinder output shaft 4 is moved upwards, so that reseting pressuring spring 7 is gradually recovered original state, so that
Left drive rod 10 and the relatively left lead screw 12 of right drive rod 11 and right lead screw 13 move upwards, so that jet piston plate 23 is upward
Movement resets, and the second air jet pipe 29 moves upwards reset, and air-breathing piston plate 19 moves downward reset, when reseting pressuring spring 7 is completely extensive
After restoring shape, jet piston plate 23, the second air jet pipe 29 and air-breathing piston plate 19 also set back, at this time hydraulic cylinder output shaft 4
It continues up, drives flash absorber 16 to move upwards, so that flash absorber 16 leaves ground, be no longer enclosed in comburant
In flash absorber 16, residue of combustion is cleared up convenient for staff.
When needing to being inflated in jet cylinder barrel 14, carbon dioxide gas is passed through in gas tube 8, titanium dioxide covers edge
Gas tube 8 enter jet cylinder barrel 14 in the remaining gas in jet cylinder barrel 14 is squeezed out from fumarole 31, when inflation completion
Afterwards, 14 internal pressure strong stability of jet cylinder barrel, sheet rubber 32 is no longer influenced by the effect of pressure difference, therefore restores closed state, by dioxy
Change carbon gas barrier in jet cylinder barrel 14.
