Step two: when the operation module main body (3) fails and a fire occurs, the temperature open fire detector (26) can detect the fire, the temperature open fire detector (26) controls the second electric push rod (34) to work through the total control transmitter (7), the output end of the second electric push rod (34) pulls the guide ring (35) downwards, the guide ring (35) drives the first drive ring (36) to move downwards, meanwhile, the transmission block (39) slides in the chute (38), at the moment, the first drive ring (36) is not meshed with the second drive ring (37), so that power is not transmitted any more, the second drive ring (37), the first gear (28), the first belt (29), the moving block (9), the middle rotating piece (10) and the detection rod (14) are not moved any more, and meanwhile, data transmission is carried out through the total control transmitter (7), and a user is informed of the control site in time;
step three: the automatic protection, the temperature open fire detector (26) is controlled by the total control transmitter (7), the electromagnetic valves (25) at the two sides of the detected fault temperature open fire detector (26) work, at the moment, the electromagnetic valves (25) are opened, liquid carbon dioxide in the storage box (11) enters the branch pipe (23) through the spray pipe (22) and is sprayed out through the electromagnetic valves (25), and a large amount of liquid carbon dioxide is sprayed at the position where the operation module main body (3) generates fire, so that the temperature is reduced or the fire is extinguished, and the operation module main body (3) is protected to the greatest extent;
Step four: when a user needs to replace a new or large-area maintenance operation module main body (3), the user controls the moving block (9), the middle rotating piece (10) and the detection rod (14) to move to one side of the main box (1) through the total control transmitter (7), at the moment, the user enables the first driving ring (36) and the second driving ring (37) to be separated through the second electric push rod (34), so that the moving block (9), the middle rotating piece (10) and the detection rod (14) stop operating, at the moment, the user controls the first electric push rod (17) to work again, at the moment, the output end of the first electric push rod (17) stretches, the detection rod (14) is enabled to move by ninety degrees through the connecting rod (18) and the first arc-shaped guide groove (16), the user cannot be influenced to replace or large-area maintenance of the operation module main body (3), after replacement or maintenance, the detection rod (14) is controlled to reset, and the second electric push rod (34) is controlled to enable the first driving ring (36) and the second driving ring (37) to be meshed with the moving block (9), the middle rotating piece (14) and the power rod (14) can be restored.
