[0015] A collection method of a gas collection device for environmental monitoring, comprising the following steps: S1. The motor drives the shaft to rotate, the shaft drives the latch gear to rotate through the transmission gear, the latch gear drives the mounting sleeve to rotate through the fixing ring, and the mounting sleeve drives the rotating disk to rotate; S2, placing multiple gas storage tanks on the temporary storage table respectively, and pushing the gas storage tanks into the clamping holes on the outer wall of the rotating disk, so that the gas storage tanks press the fixed frame, and the fixed frame slides along the outer wall of the support rod, and the second spring is stretched until the support ring on the outer wall of the gas storage tank is clamped into the clamping groove; S3, the gas tank is driven to rotate by the rotating disk, and the supporting ring on the outer wall of the gas tank slides into the first limiting groove, and the gas tank is squeezed by the inner wall of the storage tube and is fixed inside the clamping hole; S4, the rotating shaft drives the second bevel gear to rotate through the first bevel gear, drives the connecting shaft to rotate through the second bevel gear, and drives the half gear to rotate through the connecting shaft. When the half gear rotates cyclically, it can mesh with the toothed plate on one side and push the toothed plate to move downward. The toothed plate drives the air nozzle to slide downward along the fixed plate. At this time, the air nozzle drives the mounting block to slide downward along the first guide rod and squeezes the third spring. When the convex tooth on the half gear rotates to the other side, it meshes with the other toothed plate and pushes the other toothed plate to move upward. At this time, the air nozzle moves upward along the fixed plate, thereby realizing the reciprocating movement of the air nozzle up and down; S5.

The exhaust hole on the gas nozzle extends to the bottom of the fixed sleeve. S7, the second electric push rod pushes the sleeve to move upward, and the sleeve drives the stopper to squeeze the second cone sleeve, so that the stopper moves to the top of the second cone sleeve. At this time, the second electric push rod drives the stopper to move downward, and the second cone sleeve is pulled downward by the stopper. The second cone sleeve drives the piston to slide downward along the inner wall of the gas storage tank through the plug rod, so that suction is generated in the gas storage tank. At this time, the gas nozzle sucks external gas into the gas storage tank through the connecting pipe, the fixed pipe and the air intake cover; S8, the second electric push rod continues to move upward, at this time the stopper moves to the top of the first cone sleeve, the stopper pushes the first cone sleeve to slide downward along the plug rod, the tension spring is stretched, when the first cone sleeve and the second cone sleeve contact each other, at this time the sleeve drives the stopper to slide downward along the first cone sleeve and the second cone sleeve, after the stopper slides out, under the elastic force of the tension spring, the first cone sleeve moves upward and separates from the second cone sleeve, at this time the end of the gas nozzle is pulled out from the inside of the fixed sleeve, at this time the plug is plugged into the fixed sleeve under the elastic force of the fourth spring, thereby sealing the upper port of the gas storage tank; S9. The output end of the first electric push rod moves out from the positioning groove on the rotating disk. At this time, the rotating shaft drives the rotating disk to continue to rotate. At this time, the rotating disk drives the gas storage tank to continue to rotate, and multiple gas storage tanks can be inflated in turn to collect gases in different environments.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The device of the present invention can process multiple gas storage tanks at the same time, and the gas storage tanks are brought to the bottom of the gas nozzle in turn by a rotating disk for gas collection, which improves the collection efficiency and is suitable for continuous or intermittent collection of gases in different environments, thereby increasing the application scope of the device under diverse environmental conditions and improving flexibility and applicability.

[0017] 2. In the present invention, the automatic rotation and positioning of the gas storage tank are realized by driving the rotating shaft, transmission teeth, latching teeth and other components through a motor, which greatly reduces the tediousness of manual operation. The up and down reciprocating movement of the gas nozzle is controlled by mechanical structures such as half gears and toothed plates, realizing the automated process of gas collection.

[0034] Working principle: The motor 107 drives the rotating shaft 108 to rotate, the rotating shaft 108 drives the latching teeth 115 to rotate through the transmission teeth 113, the latching teeth 115 drives the mounting sleeve 111 to rotate through the fixing ring 114, and the rotating disk 121 is driven to rotate through the mounting sleeve 111; Place multiple gas tanks 301 on the temporary storage table 102 respectively, and push the gas tanks 301 into the clamping holes 122 on the outer wall of the rotating disk 121. The gas tanks 301 press the fixed frame 124, and the fixed frame 124 slides along the outer wall of the support rod 125. The second spring 127 is stretched until the support ring 302 on the outer wall of the gas tank 301 is clamped into the clamping groove 123; The gas tank 301 is driven to rotate by the rotating disk 121, and the support ring 302 on the outer wall of the gas tank 301 slides into the first limiting groove 106. The gas tank 301 is squeezed by the inner wall of the storage tube 101 and is fixed inside the clamping hole 122. The rotating shaft 108 drives the second bevel gear 203 to rotate through the first bevel gear 109, drives the connecting shaft 201 to rotate through the second bevel gear 203, and drives the half gear 204 to rotate through the connecting shaft 201. When the half gear 204 rotates cyclically, it can mesh with the tooth plate 215 on one side and push the tooth plate 215 to move downward. The tooth plate 215 drives the air nozzle 209 to slide downward along the fixed plate 205. At this time, the air nozzle 209 drives the mounting block 216 to slide downward along the first guide rod 206 and squeezes the third spring 208. When the convex tooth on the half gear 204 rotates to the other side, it meshes with the other tooth plate 215 and pushes the other tooth plate 215 to move upward. At this time, the air nozzle 209 moves upward along the fixed plate 205, so that the air nozzle 209 can reciprocate up and down. During the rotation of the rotating disk 121, the output end of the first electric push rod 105 repeatedly retracts and retracts intermittently, and the output end of the first electric push rod 105 is stuck in the positioning groove 128 at the top of the rotating disk 121. At this time, the rotating disk 121 is fixed, and when the rotating shaft 108 drives the transmission tooth 113 to rotate, the latching tooth 115 slides from the tooth groove of the transmission tooth 113, and the latching tooth 115 slides along the outer wall of the connecting rod 116, so that the first spring 117 is compressed, thereby causing a slipping phenomenon, ensuring that the rotating shaft 108 can continue to rotate, thereby driving the air nozzle 209 to move reciprocatingly upward; When the gas storage tank 301 moves to below the gas nozzle 209, the gas nozzle 209 moves downward and is inserted into the fixing sleeve 304. The gas nozzle 209 squeezes the plug 306 downward, and the plug 306 pushes the support plate 308 to slide downward along the slide rod 310. The fourth spring 311 is compressed, and the first sealing ring 305 in the fixing sleeve 304 is inserted into the sealing groove 210 on the gas nozzle 209. The exhaust hole 211 on the gas nozzle 209 extends to below the fixing sleeve 304. The second electric push rod 401 pushes the sleeve 402 to move upward, and the sleeve 402 drives the stopper 403 to squeeze the second cone sleeve 319, so that the stopper 403 moves to the top of the second cone sleeve 319. At this time, the second electric push rod 401 drives the stopper 403 to move downward, and the second cone sleeve 319 is pulled downward by the stopper 403. The second cone sleeve 319 drives the piston 313 to slide downward along the inner wall of the gas storage tank 301 through the plug rod 312, so that suction is generated in the gas storage tank 301. At this time, the gas nozzle 209 sucks external gas into the gas storage tank 301 through the connecting pipe 214, the fixing pipe 212 and the air intake cover 213; The second electric push rod 401 continues to move upward, and the stopper 403 moves to the top of the first cone sleeve 318. The stopper 403 pushes the first cone sleeve 318 to slide downward along the plug rod 312, and the tension spring 317 is stretched. When the first cone sleeve 318 and the second cone sleeve 319 contact each other, the sleeve 402 drives the stopper 403 to slide downward along the first cone sleeve 318 and the second cone sleeve 319. After the stopper 403 slides out, the first cone sleeve 318 moves upward and separates from the second cone sleeve 319 under the elastic force of the tension spring 317. At this time, the end of the gas nozzle 209 is pulled out from the inside of the fixed sleeve 304. At this time, the plug 306 is plugged into the fixed sleeve 304 under the elastic force of the fourth spring 311, thereby sealing the upper port of the gas storage tank 301. The output end of the first electric push rod 105 moves out from the positioning groove 128 on the rotating disk 121. At this time, the rotating shaft 108 drives the rotating disk 121 to continue to rotate. At this time, the rotating disk 121 drives the gas tank 301 to continue to rotate, and the interior of multiple gas tanks 301 can be inflated in turn to collect gases in different environments.
