[0042] The adjustable air inlet and outlet mechanism 8 in the above embodiment needs to be used in conjunction with carbon dioxide and oxygen sensors. The sensors need to be installed inside the cabin to monitor the air data inside the cabin 1 in real time, and need to be equipped with remote control and on-site control systems. More importantly, it needs to be equipped with a power supply system for support; the oxygen generator 11 that appears is an existing conventional technology, which uses air separation technology to produce oxygen; the gas filter is a high-efficiency filter, which is a kind of equipment used for air purification. It is made of chemical fiber or glass fiber. Through its microscopic flocculent structure, it is mainly used to remove particles larger than 0.5 microns and intercept the tiny dust contained in the air passing through the filter; the valve fan is a fan with a valve installed at the fan outlet position, which can be controlled to open and close the fan outlet, and the first valve fan 87 needs to be equipped with an air volume sensor for use; the tubes that appear inside the adjustable air inlet and outlet mechanism 8 are all elastic and can be stretched.

[0043] The specific implementation process is as follows:

[0044] When the support cabin needs to be used, it is first moved to the position where it needs to be fixed and installed inside the tunnel, and the support 3 can be used to walk to the front of the cabin door 2, and the cabin door 2 can be opened to enter the cabin body 1. The outside of the cabin body 1 is provided with an impact-resistant component, a stabilizing member 6 and an impact-resistant protective shell 5;

[0045] When a collapse occurs in the tunnel and emergency evacuation is required, the staff needs to enter the cabin 1 for evacuation. A water chamber 12 is provided inside the cabin 1, and a water storage tank 13 is installed inside the water chamber 12. The water storage tank 13 can supply water, and an oxygen chamber 9 is provided at the other end of the cabin 1. An oxygen generator 11 and a gas cylinder 10 are provided inside the oxygen chamber 9 to provide oxygen to the cabin 1.

[0046] When the collapsed position does not cover the entire cabin body 1, the first blower 87 with valve connected to the air inlet pipe 86 can be started to work, and the external air is extracted through the air inlet box 7, and the air is filtered by the gas filter inside the air inlet box 7, and then discharged into the cabin body 831 through the air inlet pipe 86, and the third blower 835 with valve is started to extract air, and the air is discharged into the air outlet cavity 843 through the elastic tube by the air guide pipe 836, and finally enters the cabin body 1 through the ventilation groove 8a from the air duct 842 at the lower end. During the process of sucking in and discharging external air, the second blower 834 with valve needs to be in a closed state;

[0047] When the carbon dioxide concentration inside the cabin 1 is high and exhaust is required, the exhaust fan 845 is started to draw gas into the exhaust cavity 844 through the ventilation groove 8a at the upper end, and then the gas is discharged to the outside through the elastic tube to the exhaust pipe 85 connected to the cover plate 8311;

[0048] During the air intake and air discharge process, the second motor 837 can be started to work, and the second motor 837 drives the driving pulley 838 to rotate. During the rotation of the driving pulley 838, the synchronous belt 839 drives the driven pulley 8310 to rotate, and the shaft rod inside it can drive the rotating rod 8312 to rotate. During the rotation of the rotating rod 8312, the guide rod 8313 and the sliding rod 8314 can start to swing. During the swing, the sliding rod 8314 can slide on the guide rod 8313, and the moving part 8315 connected to the sliding rod 8314 can slide in the strip groove 8316, so that the upper and lower ends of the box 841 move in opposite directions, thereby realizing the adjustment of the air intake position and the air discharge position. It can also be adjusted to be vertical according to the air data inside the cabin 1. If the oxygen consumption rate in the cabin 1 is large and the carbon dioxide concentration is too high, the air intake and air discharge positions can be adjusted to be vertical to improve the efficiency of air supply and air discharge. If the oxygen and carbon dioxide concentrations in the cabin 1 are balanced, the position can be adjusted to be non-vertical to avoid oxygen waste.

[0049] During the air outlet and air intake process, the positions of the two can also be adjusted synchronously over a large range to increase the flow rate of air in the cabin and reduce discomfort to people in the cabin. The first motor 822 is started to work, and the first motor 822 drives the transmission shaft 823 to rotate, and the transmission shaft 823 drives the worm 824 to rotate, and the worm gear 825 is driven to rotate during the rotation process. During the rotation of the worm gear 825, the middle connecting shaft 826 can drive the driving gear 827 to rotate, and the driving gear 827 rotates and drives the driven gear 829 to follow the rotation, and the fan-shaped gear connected to the front end of the two can follow the rotation, and the top meshing sliding tooth plate 8211 can be toggled, and the connecting plate 8212 can be moved back and forth left and right during the toggling process, so that the air collecting chamber 83 drives the air guide box 84 at the front end to move left and right. During the movement, the air intake and exhaust positions can be adjusted over a large range inside the ventilation groove 8a.

[0050] If the collapsed rocks cover a part of the air inlet position of the air inlet box 7, it can be sensed by the air volume sensor inside the first valved fan 87. When it is sensed that the air inlet volume is small, the first valved fan 87 at the covering position can be directly closed to stop the air intake to avoid energy waste. At the same time, the oxygen generator 11 needs to be started to start working, and the oxygen inside the gas cylinder 10 is extracted and discharged into the warehouse body 831 through the oxygen generator exhaust pipe 89 through the valved fan, and then transmitted and discharged into the cabin body 1 by the air duct 836. If it is necessary to prepare oxygen by extracting external air, the valved fan corresponding to the oxygen generator intake pipe 88 is started to work, and the air entering the warehouse body 831 is extracted and discharged into the oxygen generator 11 for oxygen production, and the oxygen can be stored in the gas cylinder 10.
