In large cities, urban traffic roads are generally designed with a sinking tunnel (a tunnel is a passage dug in a river above the tunnel for passing trains or subways and a tunnel is used for passing vehicles below the tunnel), and once the vehicles run into the tunnel, the water in the tunnel or the tunnel instantaneously swells when heavy storm is caused, and the vehicles can be submerged by the water when the vehicles are not evacuated. In order to strive for more emergency time for personnel and internal combustion engines in the vehicle forced to enter dangerous situations, the air flow in the air inlet pipeline is changed into a transitional reverse sealing backflow supply mode from an external air suction mode along with the continuous change of the load of the internal combustion engine, and the transitional reverse sealing backflow supply mode is also called reverse sealing air inlet. When the emergency situation can not be quickly separated by continuous self-rescue in the reverse mode, starting a multidirectional sealed air inlet mode, starting a visual inspection window or an escape window, wherein the step is a multidirectional sealed air inlet mode, if the emergency situation is still in a retention state, starting a high-pressure multidirectional air supply mode (namely, the door closing detection window, the self-rescue time is prolonged to the automatic countdown of the high-pressure mode, more self-rescue time is strived for, the high-pressure sealed air supply mode can be terminated in advance according to actual conditions, all valves and internal combustion engines or engines are closed to protect the safety of the high-pressure sealed air supply mode, and then the escape window is started for escaping self-rescue.
As shown in fig. 1-3, the embodiment discloses a 360-degree filtering intelligent anastomotic sealed oxygen supplying air intake and ventilation system, which comprises an observation escape window 1, an operation room transition bin 2 (commonly called a cab), an external circulation switching valve 3, a bidirectional blower 4, a first air intake pipeline 5, a lower air intake pipeline filter screen 7, a lower air intake pipeline port 6, an air intake pipeline controller, an upper air intake pipeline port 9, an upper air intake pipeline filter screen 8, a second air intake pipeline 10, a throttle valve 11, an engine 12 and an exhaust gas exhaust pipeline 13, wherein:
the observation escape window 1 is arranged on the transition bin 2 of the operation room, preferably on the side of the driver, so that the driver can conveniently open or close the observation escape window manually, and the observation escape window belongs to an operation switch component such as a door window or a skylight. In this embodiment, the operation room transition bin 2 performs sealing treatment.
The external circulation switching valve 3 is disposed inside the operation chamber transition bin 2 and is located at a connection position of the first air inlet pipeline 5 and the operation chamber transition bin 2, for example, an instrument panel in the operation chamber. When the escape is needed, after the engine 12 is closed, the external circulation switching valve 3 on the instrument (or below the instrument) can be conveniently closed by a driver, and in actual operation, the external circulation switching valve 3 can be controlled by a button switch of an electric control system;
