In the initial state, the sealed pad 504 is pressed and attached to the sealed ring platform 503 by the resistance spring 505 to achieve the sealing of the safety protection component 500.

[0024] A method for using an intelligent gas online monitoring and capture device includes the following steps: S1: When the intelligent gas monitoring probe 104 detects gas, the vacuum pump 107 and the second motor 208 are started, and the external air is sent into the frame 101 through the vacuum pump 107, so that a pressurized environment is formed in the frame 101, and then the activated carbon in the multiple capture screen drum assemblies 400 adsorbs and captures the gas in the air, and the second motor 208 is started. At this time, the capture screen drum assembly 400 performs a circular rotation and the capture screen drum assembly 400 performs a self-rotation rotation, so that the gas sent into the frame 101 is fully stirred and adsorbed and captured; S2: As the traveling gear 404 meshes and circles inside the outer limit gear ring 206, the stirring rod 405 forms a self-rotating stirring structure. The stirring of the stirring rod 405 ensures that the activated carbon on the capture screen drum assembly 400 can adsorb and capture the gas. S3: The frame 101 is tilted downward by the first motor 102. At this time, one end of the second straight cylinder 406 is tilted downward, and the sealing end cover 407 is opened. At this time, the activated carbon in the capture screen cylinder 401 is directly discharged, and then new activated carbon is filled into the capture screen cylinder 401, and then the sealing end cover 407 is covered to realize the replacement of the activated carbon.

[0025] The working principle of the present invention is as follows: when the present invention is used, multiple groups of capture screen drum assemblies 400 are arranged inside the frame 101, and at the same time, multiple groups of capture screen drums 401 are filled with activated carbon for adsorbing and capturing gas. When in use, when the intelligent gas monitoring probe 104 detects gas, the vacuum pump 107 and the second motor 208 are started, and the external air is sent into the frame 101 through the vacuum pump 107, so that a pressurized environment is formed in the frame 101, and then the activated carbon in the multiple groups of capture screen drum assemblies 400 adsorbs and captures the gas sent into the air.

[0026] On the basis of the above, when the intelligent gas monitoring probe 104 detects gas, the second motor 208 is started at this time, and the second motor 208 drives the central driving gear 204 to rotate. Since the outer ring gear 402, the central driving gear 204 and the inner wall gear ring 106 are on the same vertical plane, the two sides of the outer ring gear 402 are respectively meshed with the inner wall gear ring 106 and the central driving gear 204. When the central driving gear 204 rotates, since the position of the inner wall gear ring 106 is fixed, and the outer ring gear 402 is arranged between the central driving gear 204 and the inner wall gear ring 106, multiple sets of capture screen drum components 400 forms a structure that rotates in a circle in the frame 101. While rotating in a circle, the capture screen drum assembly 400 forms a structure that rotates on the first end cover assembly 200. In this way, when the capture screen drum assembly 400 rotates in a circle and when the capture screen drum assembly 400 rotates on its own, the gas sent into the frame 101 can be fully stirred, thereby ensuring the adsorption effect of the activated carbon in the capture screen drum assembly 400 on the gas. At the same time, through the self-rotation of the capture screen drum assembly 400 itself, it is ensured that each surface of the activated carbon in the capture screen drum assembly 400 can fully contact and adsorb and capture the gas.

[0027] On the basis of the above, when the capture screen drum assembly 400 rotates in a circle inside the capture bin assembly 100, the traveling gear 404 at the end of the capture screen drum assembly 400 circles and meshes on the inner side of the outer limit gear ring 206. When the traveling gear 404 meshes and circles on the inner side of the outer limit gear ring 206, the stirring rod 405 forms a self-rotating stirring structure. Through the stirring of the stirring rod 405, the activated carbon in the capture screen drum 401 is fully stirred, thereby ensuring the adsorption and capture of gas by the activated carbon on the capture screen drum assembly 400.

[0028] On the basis of the above, when the pressure inside the rack 101 is too high, the high-pressure gas will overcome the pressure of the resistance spring 505 and push the sealing pad 504 upward. At this time, the excessive pressure of the rack 101 is discharged through the closed ring platform 503 and the ventilation side pipe 502, avoiding the safety hazard caused by the excessive pressure inside the rack 101.

[0029] On the basis of the above, when it is necessary to replace the activated carbon in the capture screen drum assembly 400, the frame 101 is tilted downward by the first motor 102, and one end of the second straight cylinder 406 is tilted downward, and the sealing end cover 407 is opened. At this time, the activated carbon in the capture screen drum 401 is directly discharged, and then the discharge of the activated carbon in the capture screen drum assembly 400 is accelerated by stirring with the stirring rod 405. After the activated carbon in the capture screen drum assembly 400 is discharged, new activated carbon is filled into the capture screen drum 401, and then the sealing end cover 407 is covered.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

A method for using an intelligent gas online monitoring and capture device, using the intelligent gas online monitoring and capture device according to any one of claims 5 to 9, characterized in that: The usage steps include the following: S1: When the intelligent gas monitoring probe (104) detects gas, the air extraction pump (107) and the second motor (208) are started, and external air is sent into the frame (101) through the air extraction pump (107), so that a pressurized environment is formed in the frame (101), and then the activated carbon in the multiple capture screen drum assemblies (400) adsorbs and captures the gas in the air, and the second motor (208) is started. At this time, the capture screen drum assembly (400) performs a circular rotation and the capture screen drum assembly (400) performs a self-rotation rotation, so that the gas sent into the frame (101) is fully stirred and adsorbed and captured; S2: As the traveling gear (404) meshes and circles inside the outer limit gear ring (206), the stirring rod (405) forms a self-rotating stirring structure, and the stirring of the stirring rod (405) ensures that the activated carbon on the capture screen drum assembly (400) adsorbs and captures the gas; S3: The frame (101) is tilted downward by the first motor (102), and one end of the second straight cylinder (406) is tilted downward, and the sealing end cover (407) is opened. At this time, the activated carbon in the capture screen cylinder (401) is directly discharged, and then new activated carbon is filled into the capture screen cylinder (401), and then the sealing end cover (407) is covered to achieve the replacement of the activated carbon.
