[0031] The isolation unit 200 comprises guide rails 201 fixedly installed in the explosion-proof isolation box 103, the guide rails 201 are symmetrically provided with two, the inside of the two guide rails 201 is slidably provided with a sealing plate 202, the sealing plate 202 is used for closing the air outlet 104, the top of the explosion-proof isolation box 103 is provided with a through hole 203 matched with the shape of the sealing plate 202, and the top of the sealing plate 202 extends above the explosion-proof isolation box 103 through the through hole 203. The isolation unit 200 further comprises a pull rod 204 fixedly installed on the sealing plate 202, and the inside of the explosion-proof isolation box 103 is movably provided with a first rotating shaft 205, a second rotating shaft 206, a third rotating shaft 207 and a fourth rotating shaft 208, and the first rotating shaft 205, the second rotating shaft 206, the third rotating shaft 207 and the fourth rotating shaft 208 are all provided with belt pulleys 209. The first belt 210 is in transmission connection between the belt pulley 209 on the first rotating shaft 205 and the belt pulley 209 on the third rotating shaft 207, the second belt 211 is in transmission connection between the belt pulley 209 on the second rotating shaft 206 and the belt pulley 209 on the fourth rotating shaft 208, and the first belt 210 and the second belt 211 are both fixedly connected with the pull rod 204. The first rotating shaft 205, the second rotating shaft 206, the third rotating shaft 207 and the fourth rotating shaft 208 are symmetrically provided in pairs, the first rotating shaft 205 and the second rotating shaft 206 have the same height, and the third rotating shaft 207 and the fourth rotating shaft 208 have the same height. The third rotating shaft 207 and the fourth rotating shaft 208 are both fixedly provided with a secondary wheel 212, the third belt 213 is in transmission connection between the secondary wheel 212 on the third rotating shaft 207 and the secondary wheel 212 on the fourth rotating shaft 208, and the third belt 213 is fixedly connected with a trigger block 214.

[0032] Normal refrigeration working process: when the explosion-proof analysis cabin needs refrigeration, the air conditioner outdoor unit 101 and the air conditioner indoor unit 102 are started. The air conditioner outdoor unit 101 cools the air through refrigerant circulation, and the cooled air is transmitted to the air conditioner indoor unit 102 through the pipeline, and the air conditioner indoor unit 102 blows the cold air from the air outlet 104 of the explosion-proof isolation box 103, so as to cool the inside of the analysis cabin, so as to ensure the temperature environment required for the normal operation of the instruments and equipment in the cabin.

[0033] Special case protection workflow: when encountering dangerous situations such as fire, high temperature, etc., the ambient temperature rises to the melting temperature of the high-temperature fuse rod 217, the high-temperature fuse rod 217 melts. At this time, the spring 216 loses the constraint of the high-temperature fuse rod 217, and pulls the trigger block 214 under the action of the elastic force, and the trigger block 214 drives the third belt 213 to move. Since the third belt 213 is connected to the auxiliary wheels 212 on the third shaft 207 and the fourth shaft 208, the third shaft 207 and the fourth shaft 208 start to rotate. Because the first shaft 205 is driven by the first belt 210, and the second shaft 206 is driven by the second belt 211, and the first and second belts are fixedly connected to the pull rod 204, the first shaft 205 and the second shaft 206 also rotate, thereby driving the pull rod 204 to move. The pull rod 204 moves and pushes the sealing plate 202 to slide along the guide rail 201, and finally the sealing plate 202 closes the air outlet 104, preventing high temperature, flame, etc. in the dangerous environment from entering the inside of the explosion-proof isolation box 103, protecting the electrical elements and refrigerant system of the air conditioner indoor unit 102, and avoiding more serious dangers that may be caused by refrigerant leakage, etc.
