when the atmosphere detection device is transported, the driving part (3) drives the protective sleeve (2) to move upwards so as to enable air to enter the protective sleeve (2) through the air inlet (20); the motor drives the detection column (10) to axially rotate, the detection column (10) axially rotates to drive the rotating disc (53) to circumferentially rotate relative to the positioning disc (51) so as to enable the first exhaust port (52) and the second exhaust port (54) to be misplaced, and at the moment, air between the positioning disc (51) and the protective sleeve (2) cannot be discharged outwards through the air outlet (21);
the protective sleeve (2) continuously moves downwards, at the moment, air in the protective sleeve (2) and between the positioning disc (51) is compressed, so that the effect of protecting the detection column (10) is achieved, the detection column (10) is prevented from shaking in the transportation process, and the end part of the detection column (10) is prevented from touching the protective sleeve (2);
when air is detected, the driving part (3) drives the protective sleeve (2) to move upwards, and the water retaining ring (22) is suitable for pushing rainwater to flow above the fixed cylinder (1) and overflow outwards in the process of moving upwards of the protective sleeve (2); the protective sleeve (2) moves to the maximum travel, air is suitable for entering the protective sleeve (2) through the air inlet (20), and the detection column (10) can quantitatively sample and detect the entering air;
after the detection is finished, the first exhaust port (52) and the second exhaust port (54) are in a through state, and the protective sleeve (2) moves downwards; the protective sleeve (2) extrudes the air in the protective sleeve so that the air is discharged outwards through the air outlet (21);
at this time, air discharged from the air outlet (21) forms bubbles in rainwater stored on the water retaining ring (22), and the bubbles float upwards to drive particles on the filter screen (24) to float, so that impurities on the water retaining ring (22) are prevented from blocking the filter screen (24).
