When the present invention is applied to equipment with continuous exhaust such as a production line, it is necessary to continuously detect through the detection component 404 during the production process.

[0035] Then, the lifting motor 101 is started to drive the lifting screw 102 to rotate, driving the lifting slide bar 103 to slide on the bracket 406, so that the half gear 122 and the outer ring groove 4042 are in the same horizontal plane, and at the same time, the control motor is started to drive the moving gear 108 to rotate, driving the toothed slide plate 109 to slide on the lifting slide plate 105 toward the placement table 403, driving the guide rail 111, the long clamping rod 112, the clamping motor 113, the clamping screw 114, the connecting rod 115, the clamping nut 116, and the support 117 to slide in the direction of the placement table 403, and then the clamping motor 113 is started to drive the clamping screw 114 to rotate, driving the clamping nut 116 to move in the direction of the clamping motor 113, driving the connecting rod 115 to swing, and the connecting rod 115 pushes the long clamping rod 112 12, guide rail 111, make the two guide rails 111 and the long clamping rod 112 slide on the sliding groove 110 respectively in the direction away from the clamping motor 113, then start the moving motor 104 to drive the moving screw 118 to rotate, drive the moving nut 107 to slide in the direction away from the moving motor 104, drive the push rod 106 to move, and the push rod 106 pushes the two long clamping rods 112 to move in the direction close to the placement table 403 until the half gear 122 is coaxial with the detection component 404, then the clamping motor 113 drives the clamping screw 114 to reverse, drive the clamping nut 116 to move in the direction away from the clamping motor 113, drive the connecting rod 115 to swing, and drive the two half gears 122 to approach, until the two half gears 122 are completely fitted, at this time the half gears The wheel 122 is stuck in the outer ring groove 4042 to clamp the detection component 404, and the two half-toothed discs 119 are completely fitted with the detection gear 4041. Then the lifting motor 101 drives the lifting slide bar 103 to move in the direction close to the extraction mechanism 2, and at the same time controls the motor to reverse and drive the lifting slide plate 105 to slide in the direction of the fixed component 405. The principle is the same as above. The long clamping rod 112, the half gear 122, and the half-toothed disc 119 drive a detection component 404 to slide above a fixed component 405, and then the detection component 404 is placed in the fixed component 405, so that the two flange plates 4044 are respectively inserted into the vertical grooves of a rotating groove 4054, and the flange plates 4044 slide in the vertical grooves of the rotating groove 4054 until they are aligned with the rotating groove 4 054, when the flange plate 4044 slides in the vertical groove of the rotating groove 4054, the hollow detector 4045 pushes the sliding frame 4051 to slide in the fixed cylinder 4052, so that the sliding frame 4051 is separated from the fixed cylinder 4052, exposing the air inlet 4046, and then the rotating motor 121 is started to drive the clamping gear 120 to rotate, drive the half-toothed plate 119 and the half-gear 122 to rotate, and drive the detection component 404 to rotate, so that the flange plate 4044 is staggered with the vertical groove of the rotating groove 4054, and the position of the detection component 404 is fixed. The clamping motor 113 drives the clamping screw 114 to rotate, so that the two long clamping rods 112 are separated, and they are placed one by one with the detection component 404 in the remaining fixed component 405, and the principle is as above.

[0036] When all the detection components 404 are fixedly set on the fixed component 405, the extraction motor 201 is started to drive the extraction screw 202 to rotate, and drive the extraction slide plate 203 to slide toward the fixed component 405 until all the exhaust pipes 210 are inserted into the detection gear 4041 one by one. Then the extraction motor 212 is started to drive the extraction active gear 204 to rotate, drive the extraction ring gear 205 to rotate, drive the three extraction internal gears 206 to rotate, drive the universal joint 207 to rotate, drive the wind wheel 208 to rotate, generate airflow, and draw the airflow in the exhaust pipe 402 into the exhaust pipe 210 through the air inlet 4046. The airflow passes through the hollow detector 4045, and the hollow detector 4045 detects harmful substances.

[0037] When the detection component 404 is damaged or there is a problem with the production line and it is not notified in time, the hollow detector 4045 does not detect the substance that should be detected or the hollow detector 4045 fails the detection, the closed motor 301 is immediately started to drive the closed gear 303 to rotate and drive the closed rack 304 and the closed push block 305 to move, so that the two closed push blocks 305 are in contact, and the exhaust pipe 402 is sealed to prevent harmful substances from flowing out. When the detection is qualified, the channel of the exhaust pipe 402 remains unobstructed.

[0038] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it.
