Description

Technical Field

[0001] This utility model relates to the field of air sampling and detection technology, and in particular to a multi-bottle sampling device. Background Technology

[0002] Air sampling devices are used to collect samples of particulate matter, gases, microorganisms, or other pollutants in the air for subsequent analysis and measurement, obtaining basic data on gaseous pollution. They are widely used in environmental pollution monitoring, bioassays, and industrial hygiene, collecting and analyzing various chemical, physical, and biological factors in the air to protect human safety and health.

[0003] In existing technologies, air sampling devices generally include at least: a collector, a flow meter, and a pumping power system. The collector is mainly used to extract gaseous or vaporous pollutants. The flow rate is typically measured using an orifice or rotor flow meter to ensure stability of the air flow rate during sampling. The pumping power system usually uses a pump such as an electric vacuum sampling pump. Air enters the collector and mixes with the liquid under the action of the pumping power system for sampling. The sample in the collector is then analyzed.

[0004] For example, patent CN218584453U discloses an air sampling device, including: a fan housing with a fan installed inside; a first connector detachably connected to the fan housing and communicating with the fan's air inlet, the first connector including a first compression part and a first threaded part, the first compression part being a multi-plate structure extending from the wall of the first connector; a first compression sleeve fitted onto the first connector and having threads that helically engage with the first threaded part, when the first compression sleeve is fitted onto the first connector and the threads are tightened, the first compression sleeve will compress the first compression part, causing the multi-plate structure on the first compression part to converge; and an air guide pipe including an air inlet end and an air outlet end, the air outlet end being fitted into the first connector. Although this air sampling device has a long lifespan, its sampling efficiency is low.

[0070] like Figure 1 As shown, this utility model provides a multi-bottle sampling device, including a support body, a sampling bottle carrying turntable 1, at least two lifting components 3, a sample injection component 5, and a cover opening and closing component 4; the support body forms an upper and lower layer structure, and a support column is provided between the upper and lower layers; the sampling bottle carrying turntable 1 is rotatably connected to the lower layer of the support body, and any of the lifting components 3 are fixedly arranged between the upper and lower layers, and part of the support body is arranged close to the sampling bottle carrying turntable 1;

[0071] The upper surface of the sampling bottle carrying turntable 1 is provided with a plurality of positioning cylinders 11 for limiting the sampling bottles along the circumferential direction;

[0072] One of the lifting components 3 is used to clamp and lift the sampling bottle 2 to assist the opening and / or closing of the cap assembly 4;

[0073] Another lifting component 3 is used to clamp and lift the sampling bottle 2 to assist the sample injection component 5 in completing the sampling operation.

[0074] The sampling bottle carrier turntable 1 is used to hold the sampling bottles 2. Multiple sampling bottles 2 are arranged in a queue according to the positioning cylinder. They are sampled sequentially or at a designated location by the lifting nut 3, and then returned after sampling. The sampling bottles are arranged in an orderly manner, and the multi-bottle sampling device can sample the bottles in an orderly manner, resulting in high sampling efficiency.

[0075] In a specific embodiment, the sampling bottle carrying turntable 1 is rotatably connected to the lower layer of the support body via a rotation axis at the center of the turntable.

[0076] In a like Figure 1In the specific embodiment shown, the multi-bottle sampling device further includes a turntable driving component for driving the sampling bottle carrying turntable 1. The turntable driving component includes a turntable driving gear and a turntable driving motor that provides driving force. The side of the sampling bottle carrying turntable 1 is provided with a toothed structure, and the turntable driving gear meshes with the toothed structure. Specifically, the turntable driving motor is a stepper motor.

[0077] In the above embodiment, the turntable drive motor drives the turntable drive gear to rotate, and through meshing transmission, the sampling bottle carrying turntable 1 rotates on the lower layer of the support body.

[0078] In a like Figures 2-3 In the specific embodiment shown, a limiting structure for limiting the sampling bottle 2 is formed on the inner wall of the positioning cylinder 11. Specifically, the limiting structure includes a protrusion on the outer wall of the sampling bottle 2 that engages with a limiting groove on the inner wall of the positioning cylinder 11; or a limiting groove on the outer wall of the sampling bottle 2 that engages with a protrusion on the inner wall of the positioning cylinder 11. The limiting structure restricts the shaking of the sampling bottle 2. In one specific embodiment, the sampling bottle carrying turntable 1 is equipped with a reader for acquiring sample information from the sampling bottle 2.

[0079] In one specific embodiment, the multi-bottle sampling device includes a controller.

[0080] In a more specific embodiment, the reader is signal-connected to the controller.

[0081] In the above embodiment, the reader is used to detect information about the sampling bottles on the sampling bottle carrier turntable 1, such as the bottle number and sampling quantity, and feeds the detection information back to the controller. Specifically, the reader can be a barcode scanner. A QR code is affixed to the wall of the sampling bottle 2. The reader scans the QR code and feeds its information back to the controller. For example, the QR code may contain the bottle number and sampling quantity.

[0082] In a more specific embodiment, the turntable drive motor is signal-connected to the controller. Based on the received information about the sampling bottle 2 to be used, the controller sends a feedback signal to the turntable drive motor to start it, causing the sampling bottle-carrying turntable 1 to rotate, moving the sampling bottle 2 to the bottle cap opening / closing station 112. Based on the received information about the sampling bottle 2 corresponding to the bottle cap opening / closing station 112, the controller sends a feedback signal to the lifting assembly 3 corresponding to the bottle cap opening / closing station 112 to perform a lifting and opening operation. Based on receiving information that the opened sampling bottle with the corresponding number has reached the air sampling station 113, the controller sends a feedback signal to the lifting assembly 3 corresponding to the air sampling station 113 to perform a lifting and sampling operation. Based on receiving the number information of the sampling bottle 2 corresponding to the bottle cap opening / closing station 112, the controller sends a feedback signal to the lifting assembly 3 corresponding to the bottle cap opening / closing station 112 to perform a lifting and closing operation. The controller, based on the received number information of the sampled bottle 2 that has been sampled and closed at the bottle cap opening and closing station 112, sends a feedback signal to the turntable drive motor to drive the sampled bottle carrying turntable 1 to rotate, so that the sampled bottle 2 at the bottle cap opening and closing station 112 moves to other stations, while another sampled bottle moves to the bottle cap opening and closing station 112 to repeat the opening-sampling-closing operation.

[0083] In this application, the bottle cap switching station 112 refers to the positioning cylinder (or sampling bottle) station located on the sampling bottle carrier turntable 1, directly opposite the bottle cap switching sleeve; the air sampling station 113 refers to the positioning cylinder (or sampling bottle) station directly opposite the air pump outlet pipe 54. The positions of the bottle cap switching station 112 and the air sampling station 113 are as follows: Figure 10 As shown.

[0084] In a like Figure 1 , 5 In the specific embodiment shown, the lifting assembly 3 includes a lead screw 31, a lifting nut 32 sleeved on the lead screw 31, a clamping component 33 connected to the side of the lifting nut 32 for clamping the sampling bottle, and a lead screw drive motor 36 for driving the lead screw 31 to rotate. The lifting nut 32 is slidably connected to the support column away from the clamping component 33, and there is a rolling thread transmission between the lead screw 31 and the lifting nut 32. The clamping component 33 is used to clamp the sampling bottle 2, and clamps the sampling bottle 2 under the drive of the clamping component drive motor. The lead screw 31 rotates under the drive of the lead screw drive motor 36, and drives the lifting nut 32 to move up or down along the lead screw 31 through the rolling thread transmission, thereby driving the clamping component 33 and the sampling bottle 2 to move up or down.

[0085] In a more specific embodiment, the lead screw drive motor 36 is signal-connected to the controller. The controller receives information about the sampling bottle 2 at the bottle cap opening / closing station 112 or the air sampling station 113, and sends a feedback signal to the lead screw drive motor 36, causing it to activate the lifting nut 32 to lift the sampling bottle 2 for opening / closing or sampling operations. After the operation is completed, the controller sends a feedback signal to the lead screw drive motor 36, causing it to activate the lifting nut 32 to lower the sampling bottle 2 to the sampling bottle carrying turntable 1.

[0086] In a like Figure 1 , 4 In a more specific embodiment, the clamping component 33 is disposed opposite to any of the positioning cylinders 11 to clamp the corresponding sampling bottle. The clamping component 33 includes two clamping blocks 332 disposed opposite to each other and a clamping component drive motor. The two clamping blocks 332 are slidably connected to the side of the lifting nut 32. The clamping component drive motor is used to make the two clamping blocks 332 move relative to each other or in opposite directions to clamp or release the sampling bottle.

[0087] In a further specific embodiment, the clamping component drive motor is signal-connected to the controller. The controller receives information about the sampling bottle 2 at the bottle cap opening / closing station 112 or the air sampling station 113, and sends a feedback signal to the clamping component drive motor to activate it, driving the clamping component 33 to clamp or release. The controller also receives information about the sampling bottle 2 at the bottle cap opening / closing station 112 or the air sampling station 113, and sends a feedback signal to the clamping component drive motor to activate it, clamping the sampling bottle 2 to assist in lifting for opening / closing or sampling operations; the controller receives a signal from the lifting component 3 triggering the minimum limit sensor 35, and sends a feedback signal to the clamping component drive motor to release the sampling bottle 2.

[0088] In a like Figure 1 , 4 In a more specific embodiment, the support column is also provided with a maximum limit sensor 34 and a minimum limit sensor 35, which are used to limit the highest and lowest points reached by the lifting nut 32 along the lead screw 31, respectively.

[0089] In a further specific embodiment, the highest limit sensor 34 and the lowest limit sensor 35 are signal-connected to the controller. When the lifting nut 32 of the lifting assembly 3 corresponding to the bottle cap opening / closing station 112 is raised to contact the highest limit sensor 34, the highest limit sensor feeds a signal back to the controller, and the controller feeds a signal back to the cap opening / closing assembly 4 to perform an opening or closing operation; when the lifting nut 32 of the lifting assembly 3 corresponding to the bottle cap opening / closing station 112 contacts the lowest limit sensor 35 during descent, the lowest limit sensor 34 feeds information back to the controller, and the controller feeds a signal back to the turntable drive motor to start it, causing the sampling bottle 2 on the bottle cap opening / closing station 112 to rotate to the air sampling station 113 for sampling or rotation. The sampling process proceeds to other workstations for the next sampling bottle. When the lifting assembly 3 corresponding to the air sampling workstation 113 is raised to contact the highest limit sensor 34, the highest limit sensor 34 feeds back information to the controller. The controller then sends a signal to the sample injection assembly 5 to perform the sampling operation. When the lifting assembly 3 corresponding to the air sampling workstation 113 contacts the lowest limit sensor 35 during its descent, the lowest limit sensor 35 feeds back information to the controller. The controller then sends a signal to the turntable drive motor to start it, causing the sampling bottle 2 on the air sampling workstation 113 to rotate to the bottle cap opening and closing workstation 112 for the subsequent cap closing operation.

[0090] In a like Figure 1 , 4 In the specific embodiment shown, it also includes several sampling bottles 2, each sampling bottle 2 including a cap and a bottle body that are detachably connected to each other, and a protruding limiting eave 21 as a clamping part is formed on the outer wall of the bottle body; the multi-bottle sampling device also includes a cap opening and closing assembly 4 and a sample injection assembly 5, the cap opening and closing assembly 4 is used to open or close the cap of the sampling bottle 2; the sample injection assembly 5 is used to inject samples into the sampling bottle 2; the support body also includes an upper support located above the sampling bottle carrying turntable 1.

[0091] In a like Figure 4 , 6 In a more specific embodiment shown, the sampling bottle has a positioning hole on the protruding limiting eave (21).

[0092] In a like Figure 1 , 4 In the specific embodiment shown, the switch cover assembly 4 and the sample injection assembly 5 are mounted on the upper support and are respectively provided with a lifting assembly 3.

[0093] In a like Figure 1 , 6 In a more specific embodiment shown, the switch cap assembly 4 includes a switch sleeve 41 for rotating the sampling bottle cap to open or close the cap and a sleeve drive assembly 43 for driving the switch sleeve 41 to rotate.

[0094] In a like Figure 1 , 6 In a further specific embodiment shown, the sleeve drive component 43 includes a sleeve drive motor 432 and a sleeve gear 431 for outputting rotational power to the sleeve drive motor 432. The outer wall of the switch sleeve 41 is provided with a toothed structure for meshing with the sleeve gear. The sleeve drive motor 432 drives the sleeve gear 431 to rotate, thereby rotating the switch sleeve 41 and opening / closing the sampling bottle 2. In a further specific embodiment, the sleeve drive motor 432 is signal-connected to the controller. The controller receives information from the maximum limit sensor of the lifting component 3 corresponding to the bottle cap opening / closing station 112 and feeds back a signal to the sleeve drive motor 432 to start it. The sleeve gear 431 drives the switch sleeve 41 to rotate and unscrew or tighten the bottle cap.

[0095] In a like Figure 6 In a further specific embodiment shown, the upper support has a first through hole for the sampling bottle to pass through into the switch sleeve 41, and the lower surface of the upper support located around the first through hole is provided with a first vertical guide post 42 for assisting in positioning the sampling bottle.

[0096] In a like Figure 6 In a more specific embodiment shown, the first vertical guide post 42 and the positioning hole 211 are correspondingly arranged in the vertical direction. This simple structure enables the sampling bottle 2 to be accurately lifted into the switch sleeve 41 for opening and closing the cap, reducing operational errors.

[0097] Specifically, there are at least two first vertical guide posts 42 and at least two positioning holes 211, such as two, three, or four.

[0098] In a further specific embodiment, the inner wall of the switch sleeve 41 is provided with a limiting part that matches the outer wall of the cap of the sampling bottle 2. This limiting part is used to limit the cap and prevent it from rotating when opening or closing. Specifically, the limiting part can be a block structure or a columnar structure. In some embodiments, the switch sleeve 41 forms a receiving cavity for accommodating and limiting the cap of the sampling bottle.

[0099] In a like Figure 1 , 7In a more specific embodiment shown in ~9, the sample introduction component 5 includes an air pump 51. The air pump 51 has an inlet and an outlet connected to an air inlet pipe 52 and an outlet pipe 54, respectively, which are in communication with air. The outlet pipe 54 passes through the upper support and is exposed on the lower surface of the upper support. During sample introduction, the sampling bottle 2 is in close contact with the lower surface of the upper support and is in airflow communication with the outlet pipe. The sampling bottle 2 contains an absorption liquid. The airflow output by the air pump 51 agitates the absorption liquid, dissolving bacteria, viruses, etc. in the airflow into the absorption liquid, thus achieving the sampling purpose.

[0100] In a further specific embodiment, the air pump 51 is signal-connected to the controller. The controller receives information from the maximum limit sensor 34 of another lifting component and sends a feedback signal to the air pump 51 to initiate sample injection.

[0101] In a like Figure 8 In a further specific embodiment shown, a second vertical guide post 53 for positioning the sampling bottle is also provided on the lower surface of the upper support near the gas outlet pipe 54.

[0102] In a like Figure 8 In a more specific embodiment shown, the second vertical guide post 53 is vertically aligned with the positioning hole 211. This simple structure precisely lifts the mouth of the sampling bottle 2 to the outlet pipe 54 of the air pump 51 for sampling.

[0103] Specifically, there are at least two second vertical guide posts 53 and at least two positioning holes 211, such as two, three, or four.

[0104] Adopting such Figure 8 The multi-bottle sampling device shown below is used for air sampling, and the steps are as follows:

[0105] Multiple sampling bottles 2 (e.g., 12) are fixed in the positioning cylinder 11 of the sampling bottle carrier turntable 1. A QR code is affixed to the sampling bottle 2. The barcode scanner located at the center of the sampling bottle carrier turntable 1 scans the sampling bottle 2 on the corresponding bottle cap opening station 112 on the sampling bottle carrier turntable 1 and sends the information of the sampling bottle 2 to the controller. The controller feeds back a signal to the clamping component of the lifting assembly 3 corresponding to the bottle cap opening station 112, which drives the motor to start clamping the protruding limit eaves 21 of the sampling bottle 2. Furthermore, the controller feeds back a signal to the lead screw drive motor 36 of the lifting assembly 3 corresponding to the bottle cap opening station 112, which starts to control the lifting nut to rise, thereby lifting the sampling bottle 2 to the opening sleeve 41.

[0106] The maximum limit sensor 34 of the lifting component 3 corresponding to the bottle cap switching station 112 detects that the lifting component 3 has risen to the highest position (at this time, the bottle cap of the sampling bottle is located inside the switching sleeve). The maximum limit sensor 34 feeds the signal back to the controller. After receiving the signal, the controller feeds back the signal to the sleeve drive motor 432 to start it, which drives the switching sleeve 41 to rotate to open the cap. After the cap is opened (e.g., by setting a certain rotation time of the sleeve drive motor to determine that the cap opening is complete), the controller feeds back the signal to the lead screw drive motor 36 of the lifting component 3 corresponding to the bottle cap switching station 112 to control the lifting nut to descend, which drives the sample bottle 2 after the cap has been removed to descend back to the original positioning cylinder.

[0107] (3) When it descends to the above position, the lifting nut of the lifting assembly 3 contacts the minimum limit sensor 35, triggering the minimum limit sensor 35 to send a signal to the controller. After receiving the signal, the controller sends a signal to the turntable drive motor to drive the sampling bottle carrying turntable 1 to rotate, so that the sampling bottle 2 after the cap is removed rotates to the air sampling station 113. The air sampling station 113 is equipped with another lifting assembly.

[0108] (4) When the barcode scanner scans the sampling bottle with the corresponding number after opening, it has arrived at the air sampling station 113. After the controller obtains the information obtained by the barcode scanner, it sends a feedback signal to the lead screw drive motor 36 of the lifting component 3 corresponding to the air sampling station 113 to start it up and lift it up. This causes the sampling bottle 2 on the air sampling station 113 to move upward to the air outlet pipe 54 of the air pump 51 (the bottle mouth of the sampling bottle 2 abuts against the lower surface of the upper support). When the lifting nut contacts the maximum limit sensor 34, the controller controls the air pump 51 to start it according to the signal received from the maximum limit sensor 34, and starts the air intake sampling (the gas containing the component to be tested enters the liquid in the sampling bottle and mixes it for sampling). After the sampling is completed (the end of the sampling is determined by controlling the working time of the air pump 51), the controller sends a feedback signal to the lead screw drive motor 36 of the lifting component 3 corresponding to the air sampling station 113 to start it up so that the lifting nut can be lowered and the sampling bottle 2 can be lowered back to the air sampling station 113.

[0109] (5) When the lifting nut descends to contact the minimum limit sensor 35, the controller controls the turntable drive motor to start according to the signal of the minimum limit sensor 35, driving the sampling bottle carrying turntable 1 to rotate so that the sampling bottle 2 on the air sampling station 113 rotates to the bottle cap opening station 112 (reverse rotation); after the barcode scanner scans the number information corresponding to the sampling bottle 2 corresponding to the bottle cap opening station 112, it feeds the information back to the controller, and the controller feeds back the signal to the lead screw drive motor 36 of the lifting assembly 3 corresponding to the bottle cap opening station 112 to start so that the lifting nut can be lowered. The rising mechanism lifts the sampling bottle 2 on the bottle cap switching station 112 to the switching sleeve 41. When the lifting nut touches the maximum limit sensor 34, the controller controls the sleeve drive motor 432 to start according to the information of the maximum limit sensor 34, which drives the switching sleeve 41 to rotate (reverse) to close the cap. After the cap is closed (controlled by the rotation time), the controller controls the lead screw drive motor 36 of the lifting component 3 corresponding to the bottle cap switching station 112 to start so that the lifting nut descends, which drives the sampled and capped sampling bottle 2 to descend to the bottle cap switching station 112.

[0110] (6) The barcode scanner scans the number information of the sample bottle 2 that has been sampled and closed on the bottle cap opening and closing station 112 and feeds the information back to the controller. The controller feeds back the signal to the turntable drive motor to drive the sample bottle carrying turntable 1 to rotate, so that the sample bottle 2 on the bottle cap opening and closing station 112 moves to other stations, while another sample bottle moves to the bottle cap opening and closing station 112 to repeat the opening-sampling-closing operation.

[0111] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
