s2, the diaphragm box (5) is pressed by external air pressure, the diaphragm in the diaphragm box (5) deforms, the diaphragm box (5) drives the transmission structure to move through the transmission rod (17), and the transmission structure drives the pointer (11) to rotate through the rotating shaft (16) to measure the air pressure;
s3, external air pressure enters the sleeve (62), the air pressure presses the piston (69), the piston (69) slides in the sleeve (62), the piston (69) drives the insulating plate (63) to move through the control rod, the first spring (64) is compressed, the distance between the first electric contact block (67) and the second electric contact block (66) is reduced, when the external air pressure reaches a certain value, the first electric contact block (67) is in contact with the second electric contact block (66), at the moment, a closed loop is formed among the storage battery (4), the first electric contact block (67), the controller (610) and the second electric contact block (66), the controller (610) starts to work, the controller (610) controls the electric telescopic rod (32) to extend, the electric telescopic rod (32) drives the sealing block (33) to move downwards, the sealing head (34) blocks an air inlet channel, and the bellows (5) is prevented from being damaged due to overlarge pressure;
s4, after the glass cover cleaning device is used, the rotating column (157) drives the shell (151) to rotate, the shell (151) drives the rotating sleeve (14) to rotate along the fixing column (13), the cleaning cotton (156) cleans dirt on the glass cover (12), under the action of the elastic force of the second spring (152), the cleaning cotton (156) is in close contact with the glass cover (12), the cleaning effect on the glass cover (12) is good, the cleanness of the glass cover (12) is guaranteed, and viewing is prevented from being influenced.
