All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Reference Figures 1 to 8This utility model provides an environmental atmospheric sampling device for environmental engineering testing, including a main body 1, and further including a rotating mechanism 2, a gas collection mechanism 3, and a storage mechanism 4. The top end of the main body 1 is fixedly connected to the bottom end of the gas collection mechanism 3, the inner side wall of the main body 1 is movably connected to the side of the rotating mechanism 2, and the side of the storage mechanism 4 is movably connected to the inner side wall of the rotating mechanism 2. The main body 1 includes a base 101, the top end of the base 101 is fixedly connected to a housing 102, and the side of the housing 102 is movably connected to a sealing door 103 via a pin.

The output shaft of the stepper motor 207 is fixedly connected to the bottom end of the turntable 201. The top end of the turntable 201 is fixedly connected to a support frame 204. The top end of the support frame 204 is fixedly connected to an mounting ring 203. The storage mechanism 4 includes a sealing bag 401. The top end of the sealing bag 401 is fixedly connected to a splice 402. The side of the splice 402 is fixedly sleeved with a limit ring 403. The side of the limit ring 403 is movably connected to the inner wall of the side of the mounting ring 203. The gas collection mechanism 3 includes a vacuum pump 301. The bottom end of the vacuum pump 301 is connected to the base 1. The top of the housing 102 is fixedly connected to the air pump 301, and the side of the air pump 301 is fixedly connected to the air inlet pipe 304. The top inner wall of the housing 102 is fixedly connected to the storage mechanism 4, and the bottom of the automatic telescopic rod 303 is fixedly connected to the connecting seat 302. The top of the connecting seat 302 is fixedly connected to the air outlet pipe 305, and the top of the air outlet pipe 305 is fixedly connected to the bottom of the air pump 301. The bottom of the connecting seat 302 is movably connected to the top of the splice joint 402. The top of the turntable 201 is provided with multiple mounting rings 203, and the opening of the mounting rings 203 is made of elastic material. When in use, the limiting ring 403 is inserted into the mounting ring 203. When sampling, the stepper motor... Machine 207 drives turntable 201 to rotate, causing storage mechanism 4 to rotate sequentially to directly below connecting seat 302. Automatic telescopic rod 303 pushes connecting seat 302 downward, so that the bottom end of connecting seat 302 is tightly attached to the top end of splice joint 402. Air pump 301 operates to draw air through air inlet pipe 304 and delivers the air to the sealed bag 401 for storage through air outlet pipe 305, splice joint 402 and connecting seat 302. After completion, automatic telescopic rod 303 drives connecting seat 302 upward, so that connecting seat 302 is separated from splice joint 402. Turntable 201 is rotated again to send the air sample into the next storage mechanism 4, reducing manual operation and improving work efficiency.

[0026] A pressure spring 408 is fixedly connected to the inner wall of the bottom end of the splice joint 402. A top plate 409 is fixedly connected to the top end of the pressure spring 408. A sealing plug 405 is fixedly connected to the top end of the top plate 409. A sealing groove 406 is formed on the inner wall of the top end of the splice joint 402. The side of the sealing groove 406 fits against the side of the sealing plug 405. A second pressure rod 404 is fixedly connected to the top end of the sealing plug 405. A first pressure rod 306 is fixedly connected to the inner wall of the side of the connecting seat 302. A through groove 407 is formed at the bottom end of the top plate 409. The storage mechanism 4 does not use... When in use, the pressure spring 408 pushes the top plate 409 upward, and the sealing plug 405 is tightly pressed against the sealing groove 406, blocking the splice joint 402 and keeping the sealing bag 401 sealed. At this time, the second pressure rod 404 extends out of the top of the splice joint 402. When the connecting seat 302 is in contact with the splice joint 402, the first pressure rod 306 pushes the second pressure rod 404 downward, thereby separating the sealing plug 405 from the sealing groove 406. Air enters the interior of the splice joint 402 through the gap between the sealing plug 405 and the sealing groove 406 and the through groove 407, and finally enters the interior of the sealing bag 401.

[0027] The bottom of the connector 302 is provided with a splicing groove 307, and the top of the sealing plug 405 and the splicing joint 402 are uniformly conical. The bottom of the splicing groove 307 and the top of the splicing joint 402 fit together, so that the sealing plug 405 can be inserted into the sealing groove 406 and the top of the splicing joint 402 can be inserted into the splicing groove 307.

[0028] Among them, a pressure block 205 is fixedly connected to the top of the turntable 201 corresponding to the position of the storage mechanism 4, and a control device 202 is fixedly connected to the top of the base 101 corresponding to the position of the pressure block 205. When the pressure block 205 rotates with the turntable 201, when the storage mechanism 4 moves directly below the connecting seat 302, the pressure block 205 moves to the control device 202. At this time, the pressure block 205 contacts the control device 202, and the control device 202 controls the gas collection mechanism 3 to automatically start sampling.

[0029] The control device 202 includes a mounting block 2021. A return spring 2022 is fixedly connected to the inner wall of the bottom end of the mounting block 2021. A mounting bracket 2023 is fixedly connected to the top end of the return spring 2022. A buffer spring 2025 is fixedly connected to the inner wall of the bottom end of the mounting block 2021. A pressure switch 2026 is fixedly connected to the top end of the buffer spring 2025. When the pressure block 205 moves to the position of the control device 202, the bottom end of the pressure block 205 contacts the roller 2024, causing the mounting bracket 2023 to move downward and contact the pressure switch 2026, causing the pressure switch 2026 to separate. The pressure switch 2026 controls the gas collection mechanism 3 to start automatically.

[0030] The top of the mounting bracket 2023 is movably connected to a roller 2024 via a pin, and the bottom of the pressure block 205 has an inclined surface 206. When the pressure block 205 moves to the position of the control device 202, the roller 2024 is fixed along the inclined surface 206, which facilitates the roller 2024 to move below the pressure block 205 and avoids jamming.

[0031] The bottom end of the placement groove 104 is movably connected to a support wheel 208 via a pin. The top end of the support wheel 208 is movably connected to the bottom end of the turntable 201. The support wheel 208 supports the turntable 201. When the turntable 201 rotates, the support wheel 208 rolls along the turntable 201, reducing the friction between the turntable 201 and the placement groove 104.

[0032] The working principle of this utility model is as follows: When the limiting ring 403 is inserted into the mounting ring 203, the pressure spring 408 pushes the top plate 409 upward, and the sealing plug 405 tightly adheres to the sealing groove 406, blocking the splice joint 402 and keeping the sealing bag 401 sealed, with no air inside the sealing bag 401. The stepper motor 207 is started to drive the turntable 201 to rotate, causing the storage mechanism 4 to rotate with the turntable 201 to be directly below the connecting seat 302. At this time, the pressure block 205 moves with the turntable 201 to the position of the control device 202. The bottom end of the pressure block 205 contacts the roller 2024, causing the mounting bracket 2023 to move downward and contact the pressure switch 2026, causing the pressure switch 2026 to disengage. The pressure switch 2026 controls the stepper motor 207 to stop, and simultaneously controls the air collecting mechanism 3 to automatically... When the automatic telescopic rod 303 is activated, it pushes the connecting seat 302 downward, so that the bottom end of the connecting seat 302 is tightly attached to the top end of the splice joint 402. At this time, the top end of the splice joint 402 is tightly attached to the splicing groove 307. The first pressure rod 306 pushes the second pressure rod 404 downward, so that the sealing plug 405 is separated from the sealing groove 406. The air pump 301 operates to draw air through the air inlet pipe 304 and delivers the air to the inside of the sealing bag 401 for storage through the air outlet pipe 305, the splice joint 402 and the connecting seat 302. After completion, the automatic telescopic rod 303 drives the connecting seat 302 upward, so that the connecting seat 302 is separated from the splice joint 402. The sealing plug 405 blocks the sealing groove 406 again. The stepper motor 207 is rotated again to send the air sample into the next storage mechanism 4 for storage.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
