[0025] During operation, the sealing sleeve 26 is fixed by opening the flow slot 25 through the mounting plate 24. When the movable rod 27 moves downward in the inner wall of the sealing sleeve 26, a gap is generated between the sealing sleeve 26 and the movable rod 27, which is beneficial to the isolation and circulation of air.

[0026] Furthermore, a push rod 31 is fixedly mounted on the top of the linkage plate 28, a cylinder 29 is fixedly mounted on the top of the push rod 31, and a mounting plate 24 is fixedly mounted on one side of the cylinder 29;

[0027] During operation, the cylinder 29 is driven to cause the push rod 31 to move in and out of the cylinder, so that one end of the push rod 31 drives the linkage plate 28 to move up and down. During the operation, the linkage plate 28 links the movable rod 27 to move in the sealing sleeve 26, thereby controlling the air circulation in an active manner.

[0028] Furthermore, a mounting plate 24 is fixedly installed on the top of the fixing frame 1, four fixing plates 21 are fixedly installed around the fixing frame 1, and a support plate 32 is fixedly installed on one side of the fixing frame 1;

[0029] During operation, the installation of the fixing frame 1 is helpful to ensure the overall support, and the cooperation with the fixing plate 21, the installation plate 24 and the support plate 32 is helpful to make the interior of the device airtight.

[0030] Furthermore, an exhaust slot 22 is provided on one side of the fixed plate 21, and a centrifugal fan 23 is fixedly installed on the inner wall of the exhaust slot 22;

[0031] During operation, by installing the centrifugal fan 23, the centrifugal fan 23 is helpful to guide the collected air during operation, thereby realizing the replacement of the collected air.

[0034] Furthermore, a support frame 34 is fixedly installed on the top of the remote mainboard 33, and an air detector 35 is fixedly installed on one side of the support frame 34;

[0035] When working, the air detector 35 adopts the principle of high-sensitivity electrochemical sensor, combined with single-chip technology and network communication technology, and can continuously detect SO2, NO2, O3, CO, H2S, NH3, and HF gases in the atmosphere.

[0036] Working principle: The push rod 31 is moved by driving the cylinder 29, and one end of the push rod 31 slides in the inner wall of the sealing sleeve 26 through the linkage plate 28 to link the movable rod 27. When the movable rod 27 moves downward, a gap is generated between the movable rod 27 and the sealing sleeve 26 to allow air to circulate. At the same time, the centrifugal fan 23 is driven to guide the flow of air inside the fixed plate 21, so that the air is discharged outward through the exhaust groove 22, and fresh air enters the fixed plate 21 from the sealing sleeve 26. When the replacement reaches a certain extent, the cylinder 29 is driven to make the movable rod 27 fit tightly with the sealing sleeve 26, so that the inside of the fixed plate 21 is in a closed state, and then the air detector 35 analyzes the air collected inside the fixed plate 21, and the analysis data is uploaded to the remote cloud by the remote mainboard 33 for staff to review.
