Description

Technical Field

[0001] The invention relates to a water body sampling device, in particular to a filling and packaging mechanism for water body sampling and a corresponding water body automatic sampling system. Background Art

[0002] Water sampling devices are widely used in environmental monitoring, water quality testing, and other fields, primarily for collecting water samples from different water areas and stratified layers. While existing water sampling devices can automatically obtain water samples, the filling, packaging, and storage of the sampling bottles still rely heavily on manual operations. This not only results in complex and inefficient operations, but also reduces the device's level of automation, making it unable to meet the needs of large-scale, multi-regional water sampling.

[0003] Specifically, the filling, packaging and storage of sampling bottles are usually carried out in stages: first, the water sample is filled into the sampling bottle; then, the mouth of the sampling bottle is sealed; finally, the sampling bottle is properly stored and prepared for subsequent use. However, the above process usually involves multiple independent devices and requires manual intervention. For example, the staff fills the water sample obtained by the water sampling device into the sampling bottle through a water pump, then transfers the sampling bottle to the packaging equipment to seal the bottle mouth, and finally transfers the sampling bottle to the sampling box for storage. This method often has the following problems:

[0004] One is the low integration. When the sampling bottles are transferred between multiple independent devices, operational errors are prone to occur, such as misplacing or missing sampling bottles.

[0005] The second is that manual intervention increases the probability of sample contamination, affecting the accuracy of water quality test data;

[0006] Third, the degree of automation is low, and it is impossible to automatically replace and store a large number of collection bottles in a short period of time, making it difficult to meet high-density sampling tasks.

[0007] At present, some water sampling devices attempt to simplify the replacement and packaging process of sampling bottles by improving mechanical arms or automated control systems, but these systems are often complex in design and high in cost, and still fail to fully solve the automation requirements for integrated filling, packaging, and storage of sampling bottles. In actual application, these systems not only increase the size and energy consumption of the equipment, but also have certain limitations in terms of efficiency and reliability. For example, the Chinese invention patent with authorization announcement number CN105466728B discloses a structure that uses a rotating mechanism to switch sample bottles and uses a water pump to collect water samples. It solves the problem of automatic replacement and storage of sampling bottles, but cannot seal the sample bottles in time, resulting in difficulty in ensuring the validity of the collected water samples.

[0008] Therefore, there is an urgent need for an automated water sampling device that can integrate the functions of sampling bottle filling, packaging and storage, which can reduce manual intervention while improving the efficiency and accuracy of water sample collection. Summary of the Invention

The high reliability of the seal ensures the integrity and safety of the water sample during transportation and storage, providing reliable data support for water quality analysis.

[0049] In summary, the present invention demonstrates high sampling accuracy and reliability, adapting to diverse sampling requirements and meeting the diverse monitoring needs in complex aquatic environments.

[0080] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and understand the present invention and are not intended to limit the present invention.

[0081] This embodiment discloses a filling and packaging mechanism 4 for water sampling, such as Figures 1 to 7 As shown, the water sampling filling and packaging mechanism 4 includes an impeller module 7 , an automatic filling module 8 and an automatic capping module 9 .

[0082] A. Impeller module 7

[0083] The impeller module 7 can convert the kinetic energy and gravitational potential energy of the water flow into a rotational driving force. Figures 3 to 5As shown, the impeller module 7 includes a lifting base 101 fixed on the base plate, an impeller housing 102 fixed on the lifting base 101, and an impeller 103 rotatably assembled in the impeller housing 102. Figure 5 As shown, a water inlet 104 is provided on the top of the impeller housing 102 and a water outlet 105 is provided on the bottom; a rotary power output shaft 106 is assembled at the center of the impeller 103 , and the rotary power output shaft 106 extends to the outside of the impeller housing 102 .

[0084] During operation, the water sample enters the impeller housing 102 from the water inlet 104, impacts the impeller 103, and is then discharged from the impeller housing 102 from the water outlet 105; the impeller 103 rotates under the impact of the water sample, and the generated rotational driving force is output outwardly through the rotational power output shaft 106.

[0085] The aforementioned base plate is used in the embodiment to integrate the impeller module 7, the automatic filling module 8, and the automatic capping module 9, and to realize their assembly in the hull 1. In this embodiment, the base plate is a triangular base plate 10, but of course the base plate can also be configured as a rectangle, trapezoid, or circle, etc. depending on the situation.

[0086] B. Automatic filling module 8

[0087] The automatic filling module 8 is used to automatically fill the water sample into the sampling bottle. Figure 6 As shown, the automatic filling module 8 includes a filling housing 201 , a diverter 202 , a telescopic water outlet 203 , a return spring 204 and a valve 205 .

[0088] The filling shell 201 is fixed on the triangular base plate 10 through the filling fixed base, and includes a lower shell 206 and an upper cover 207. The upper cover 207 is provided with a water pressure port 208 and a water discharge port 209, and the bottom end of the lower shell 206 is provided with an outlet. The diverter 202 is fixed in the filling shell 201, as shown in FIG. Figure 7 As shown, the diverter 202 divides the inner cavity of the filling shell 201 into an upper chamber and a lower chamber. Furthermore, the diverter 202 includes a transverse sealing plate 210 and a plug 211 fixed at the center of the transverse sealing plate 210. The transverse sealing plate 210 is provided with a plurality of through holes for connecting the upper chamber and the lower chamber. The telescopic water outlet 203 is sleeved in the filling shell 201 and is located in the lower chamber. Figure 6As shown, the telescopic water outlet 203 comprises a ring plate 212 with a through-hole and a water outlet pipe 213 fixed to the through-hole of the ring plate 212. The shape and size of the ring plate 212 are compatible with the lower chamber; the inner diameter of the water outlet pipe 213 is compatible with the outer diameter of the plug 211, and the outer diameter of the water outlet pipe 213 is compatible with the diameter of the outlet of the filling housing 201. An O-ring 214 is installed at the outlet of the filling housing 201, contacting the outer wall of the water outlet pipe 213 to improve sealing. In this embodiment, two O-rings 214 are provided.

[0089] like Figure 7 As shown, the plug 211 in the diverter 202 is placed into the water outlet pipe 213 of the telescopic water outlet 203 from above, and the diverter 202 and the telescopic water outlet 203 cooperate to form a temporary water storage space in the upper part of the lower chamber.

[0090] The water pressure port 208 and the water outlet 209 of the filling housing 201 are both communicated with the upper chamber of the filling housing 201, and a valve 205 is provided on the water outlet 209. In this embodiment, the valve 205 is a solenoid valve.

[0091] The return spring 204 is placed on the telescopic water outlet 203. Figure 7 As shown, the return spring 204 is located in the lower chamber and is used to retract the telescopic water outlet 203 and return it to the lower chamber.

[0092] Based on the water pressure, the telescopic water outlet 203 can be extended into the sampling bottle on the filling station to perform the filling action. Specifically, during operation, the water pressure port 208 of the filling shell 201 is connected to the water outlet 105 of the impeller module 7, and the solenoid valve is closed. The water sample enters the upper chamber of the filling shell 201 through the water pressure port 208. After the upper chamber is filled with the water sample, the water sample exerts pressure on the telescopic water outlet 203 through the through hole of the diverter 202 (the pressure gradually becomes greater than the elastic force of the reset spring 204), pushing the telescopic water outlet 203 downward, and the water sample is stored in the temporary water storage space; when the telescopic water outlet After 203 moves down to the diverter 202 and the plug 211 is separated from the outlet pipe 213 of the telescopic water outlet 203, the water sample flows out from the telescopic water outlet 203; when the sampling is completed, the water pressure port 208 stops taking in water, the solenoid valve opens, and the water sample in the upper chamber and the temporary water storage space is discharged from the drain port 209. The pressure of the water sample on the telescopic water outlet 203 gradually becomes less than the elastic force of the reset spring 204. Under the elastic force of the reset spring 204, the telescopic water outlet 203 moves upward and resets.

[0093] It should be noted that the length of the plug 211 of the diverter 202 in this embodiment is greater than the distance between the bottom end of the telescopic water outlet 203 and the mouth of the sampling bottle at the filling station, but less than the length of the outlet pipe 213 of the telescopic water outlet 203. This dimensioning ensures that the plug 211 will only be separated from the telescopic water outlet 203 when the bottom end of the telescopic water outlet 203 is inserted into the mouth of the sampling bottle, allowing the water sample to flow out of the telescopic water outlet 203. This design can effectively reduce splashing of water during filling.

[0094] C. Automatic capping module 9

[0095] The automatic capping module 9 is used to seal the sampling bottle after the sampling bottle is filled to prevent water sample leakage. Figure 3 and Figure 4 As shown, the automatic capping module 9 includes a bottle cap collector, a sampling bottle capping device 309 and a capping assembly.

[0096] Specifically, the bottle cap collector includes a cap storage bin 301 fixed to a triangular base plate 10 and a cap guide 302 connected to the outlet of the cap storage bin 301. The cap guide 302 is inclined from the outlet of the cap storage bin 301 to the cap outlet. The cap outlet corresponds to the bottle mouth of the sampling bottle at the filling station. The bottle caps are stored in a stacked form in the cap storage bin 301. Under the action of gravity, the bottle caps slide one by one from the outlet of the cap storage bin 301 along the cap guide 302 to the cap outlet, and then fall from the cap outlet to the mouth of the sampling bottle to be packaged.

[0097] The capping assembly is an offset crank slider mechanism that is connected to the rotary power output shaft 106 of the impeller module 7 and is used to control the action of the sampling bottle capping device 309 to buckle the bottle cap at the cap outlet onto the bottle mouth of the sampling bottle. Figure 3 As shown, the gland assembly includes a first gear 303, a second gear 304, a transmission connecting rod 305 and a gland guide rail 306. The first gear 303 is assembled on the rotary power output shaft 106 and is in transmission connection with the rotary power output shaft 106; the second gear 304 is rotatably assembled on the lifting base 101 of the impeller module 7 and meshes with the first gear 303; the gland guide rail 306 is fixed on the triangular base plate 10 and has a through slot 307 set in the vertical direction; the first end of the transmission connecting rod 305 is rotatably assembled on the edge of the second gear 304, and the second end is limited in the through slot 307 of the gland guide rail 306, limiting the movement trajectory of the second end to the vertical direction. During operation, the rotary power output shaft 106 drives the first gear 303 to rotate, the first gear 303 meshes with the second gear 304, and the second gear 304 rotates synchronously, driving the transmission connecting rod 305 to swing (the first end of the transmission connecting rod 305 performs circular motion, and the second end performs lifting motion).

[0098] like Figure 4 As shown, a vertical slide rail 308 is further provided on the gland guide rail 306 along the vertical direction.

[0099] The sampling bottle capper 309 is assembled via a slider onto the vertical rail 308 of the capping guide 306, corresponding to the sampling bottle mouth at the filling station. The sampling bottle capper 309 in this embodiment is a conventional structure, connected to the second end of the transmission connecting rod 305. Driven by the transmission connecting rod 305, it rises and falls along the vertical rail 308 to automatically cap the bottle.

[0100] The water sampling filling and packaging mechanism 4 disclosed in this embodiment is used to automatically fill and package the sampling bottle. The specific working process is as follows:

[0101] Filling: The water sample enters the impeller housing 102 from the water inlet 104, impacts the impeller 103, and is then discharged into the filling housing 201 from the water outlet 105. The water sample accumulates in the filling housing 201, and the water pressure is used to push the telescopic water outlet 203 downward into the mouth of the sampling bottle. When the telescopic water outlet 203 moves down to the plug 211 of the diverter 202 and is separated from the water outlet pipe 213 of the telescopic water outlet 203, the water sample in the filling housing 201 flows out from the telescopic water outlet 203 and is filled into the sampling bottle; after the filling is completed, the solenoid valve on the drain outlet 209 is opened, so that the water sample in the filling housing 201 is discharged from the drain outlet 209, completing the pressure relief, and under the elastic force of the reset spring 204, the telescopic water outlet 203 moves upward to complete the reset.

[0102] Packaging: After retractable water outlet 203 is reset, the sampling bottle needs to be moved from below the retractable water outlet 203 to below the capping assembly (this is achieved in this embodiment using the one-way toggle rotary module 22 described below). The rotary power output shaft 106 of the impeller module 7 provides rotational power to the capping assembly. This, through the offset crank slider mechanism formed by the first gear 303, the second gear 304, the transmission connecting rod 305, and the capping guide rail 306, drives the sampling bottle capping device 309 to snap the bottle cap at the capping outlet onto the mouth of the sampling bottle below.

[0103] This embodiment also discloses a water body automatic sampling system, such as Figure 8 and Figure 9 As shown, the automatic water sampling system includes a hull 1, a sampling mechanism 3 mounted on the hull 1, a water sampling filling and packaging mechanism 4, and a sampling bottle transport mechanism 5. The water sampling filling and packaging mechanism 4 adopts the structure disclosed above.

[0104] The hull 1 includes a frame 2 and a shell covering the frame 2 for floating on the water. In order to meet the maneuverability requirements, the hull 1 in this embodiment is provided with a power system. Figure 8 and Figure 9 As shown, the power system is a plurality of vector steering power devices 11 assembled on the bottom of the hull 1.

[0105] 1. Sampling mechanism 3

[0106] like Figure 9 As shown, the sampling mechanism 3 is assembled at the front end of the hull 1 to collect water samples at different depths. Figure 10 As shown, the sampling mechanism 3 includes a winding frame 12, a sampling tube 13, a drive assembly, and a water pump. The winding frame 12 is mounted on the front end of the hull 1's frame 2. The sampling tube 13 is wound around the winding frame 12, with one end of the sampling tube 13 extending into the sampling water area as a water inlet and the other end connected to the water pump as a water outlet. The drive assembly is a drive motor 14, which is connected to the winding frame 12 via a gear train. During operation, the drive assembly controls the forward or reverse rotation of the winding frame 12, thereby lowering or retracting the sampling tube 13 into the water.

[0107] The water pump in this embodiment is a double-acting vane pump 15, driven by a DC motor 16. Specifically, the double-acting vane pump 15 and the DC motor 16 are connected via a flexible coupling 17. The water inlet of the double-acting vane pump 15 is connected to the water outlet of the sampling tube 13 via a manual quick-change connector 18. The water outlet of the double-acting vane pump 15 is then connected to the water inlet 104 of the impeller module 7 in the water sampling filling and packaging mechanism 4.

[0108] 2. Sampling bottle transport mechanism 5

[0109] like Figure 9 As shown, the sampling bottle transfer mechanism 5 is assembled at the rear end of the hull 1 and is used to control the flow of the sampling bottles at the filling station.

[0110] It should be noted that the sampling bottle transport mechanism 5 in this embodiment needs to be used in conjunction with the rotary sampling bottle collection rack 6. The rotary sampling bottle collection rack 6 is an existing structure, specifically as shown in FIG. Figure 21 As shown, its structure is not described here in detail.

[0111] like Figure 11 As shown, the sampling bottle transport mechanism 5 includes an empty bottle pushing module 19 , a filling and fixing bottle module 20 and a full bottle storage module 21 .

Figure 12As shown. Bosses are provided on the edges of the first parallel guide rails 401 for sampling bottles, and the aforementioned rotary sampling bottle collection rack 6 can slide freely within the bosses on both sides of the first parallel guide rails 401 for sampling bottles. A support push plate 403 is fixed to the front end of the leaf-shaped flexible spring 402. The leaf-shaped flexible spring 402 contacts the rotary sampling bottle collection rack 6 via the support push plate 403 to push it to slide on the first parallel guide rails 401 for sampling bottles, thereby pushing the rotary sampling bottle collection rack 6 toward the filling and fixing bottle module 20.

[0114] (2) Filling and bottle setting module 20

[0115] The filling and fixing bottle module 20 comprises a semicircular guide rail 501 for sampling bottles connected to the outlet of the first parallel guide rail 401 for sampling bottles and a split-type switch door module mounted on the frame 2 of the hull 1. Figure 13 As shown, the edge of the sampling bottle semicircular guide rail 501 is also provided with bosses, and the rotary sampling bottle collecting rack 6 can slide freely in the bosses on both sides of the sampling bottle semicircular guide rail 501.

[0116] The split-type switch door module is used to temporarily position the rotary sampling bottle collection rack 6 pushed by the empty bottle pushing module 19 at the filling station. Figure 13 and Figure 14 As shown, the split-door module includes a first split-door 502, a second split-door 503, and a vertical shaft drive assembly 504. The first split-door 502 is mounted at the entrance of the semicircular sampling bottle guide 501 and controls the input of the rotating sampling bottle collection rack 6. The second split-door 503 is mounted at the exit of the semicircular sampling bottle guide 501 and controls the output of the rotating sampling bottle collection rack 6. The vertical shaft drive assembly 504 is in driving connection with the rotary power output shaft 106 of the impeller module 7 in the water sampling filling and packaging mechanism 4, controlling the timely opening or closing of the first and second split-doors 502, 503.

[0117] The structure of the first split-opening door 502 is the same as that of the second split-opening door 503. This embodiment takes the structure of the first split-opening door 502 as an example for detailed description. Figure 15 As shown, the first double-opening door 502 includes a left door 505 and a right door 506 that are rotatably mounted on the frame 2 of the hull 1 and are arranged opposite to each other, a parallel linkage mechanism mounted between the left door 505 and the right door 506 for controlling the synchronous opening or closing of the left door 505 and the right door 506, and an action trigger component.

[0118] Both the left door 505 and the right door 506 comprise a rigidly connected column and door leaf. The upper and lower ends of the column of the left door 505 are pivotally mounted on the gantry 2 via support bases 507. Similarly, the upper and lower ends of the column of the right door 506 are pivotally mounted on the gantry 2 via support bases 507. In this embodiment, the support bases 507 are equipped with torsion springs to return the door leaf to its original position after opening.

[0119] like Figure 15 As shown, the parallel linkage mechanism includes a first link 508, a second link 509, a third link 510, and a fourth link 511, which are hingedly connected in sequence. The free end of the first link 508 is fixedly connected to the top of the column of the left door 505, and the free end of the fourth link 511 is fixedly connected to the top of the column of the right door 506. The parallel linkage mechanism also includes a fixed guide rail 512 fixedly mounted on the frame 2 of the hull 1. A fixed slider is slidably mounted on the fixed guide rail 512, and the fixed slider is rotatably connected to the middle portion of the third link 510.

[0120] The action trigger assembly includes a paddle 513 and a toggle cam 514 positioned corresponding to the paddle 513. The paddle 513 is fixed to the column of the left door 505 or the right door 506. In this embodiment, the paddle 513 is fixed to the column of the left door 505; the toggle cam 514 is rotatably mounted on the above-mentioned triangular base plate 10.

[0121] During operation, the toggle cam 514 rotates to toggle the paddle 513, and the paddle 513 drives the left door 505 to rotate clockwise with its column as the axis, and drives the right door 506 to rotate counterclockwise with its column as the axis through the parallel linkage mechanism, so that the left door 505 and the right door 506 are in an open state; when the toggle cam 514 rotates to disengage the paddle 513, under the action of the torsion spring of the support base 507, the left door 505 and the right door 506 rotate back to their original positions and are in a closed state.

[0122] The vertical shaft transmission assembly 504 is used to drive the toggle cam 514 to rotate. Figure 14 As shown, the vertical axis transmission assembly 504 includes an input shaft 515 that is transmission-connected to the rotary power output shaft 106 in the impeller module 7, a first transmission link 516 hinged to the input shaft 515, a Z-type transmission link 517 hinged to the first transmission link 516, a second transmission link 518 hinged to the Z-type transmission link 517, an output shaft 519 hinged to the second transmission link 518, a transmission crank 520 that is transmission-connected to the output shaft 519, and a parallelogram transmission link 1 521 and a parallelogram transmission link 2 522 that are respectively hinged to the transmission crank 520 through the first end.

[0123] The input shaft 515 in the vertical shaft transmission assembly 504 is horizontally arranged, and the output shaft 519 is rotatably assembled on the triangular base plate 10 via an L-shaped base 523. The output shaft 519 is vertically arranged. In addition, the output shaft 519 in this embodiment is connected to the transmission crank 520 via a second flexible coupling 524.

[0124] Further, such as Figure 14 As shown, the second end of the parallelogram transmission link 1 521 is hinged to the toggle cam 514 of the first double-leaf switch door 502 , and the second end of the parallelogram transmission link 2 522 is hinged to the toggle cam 514 of the second double-leaf switch door 503 .

[0125] During operation, the vertical axis transmission assembly 504 converts the horizontal rotational force of the rotary power output shaft 106 into a vertical rotational force (achieved by the flipping movement of the Z-shaped transmission link 517 in the vertical axis transmission assembly 504). The vertical axis transmission assembly 504 is similar to two vertically arranged bevel gears; the vertical rotational force is used to drive the transmission crank 520 to rotate, and then the toggle cam 514 is driven to rotate through the parallelogram transmission link 1 521 and the parallelogram transmission link 2 522.

[0126] (3) Full bottle storage module 21

[0127] The full bottle storage module 21 includes a second parallel guide rail 601 for sampling bottles and a pushing unit 602, which are assembled at the rear end of the hull 1 and the frame 2. The second parallel guide rail 601 for sampling bottles is parallel to the first parallel guide rail 401 for sampling bottles, and the inlet of the second parallel guide rail 601 for sampling bottles is connected to the outlet of the semicircular guide rail 501 for sampling bottles. Figure 12 or Figure 16 As shown, the edge of the second parallel guide rail 601 for sampling bottles is also provided with bosses, and the rotary sampling bottle collecting rack 6 can automatically slide in the bosses on both sides of the second parallel guide rail 601 for sampling bottles.

[0128] The pushing unit 602 is used to push the rotary sampling bottle collecting rack 6 to the end of the second parallel guide rail 601 for the sampling bottles. Figure 16 and Figure 17 As shown, the pushing unit 602 includes a longitudinal moving unit and a pushing unit 602. The longitudinal moving unit is arranged along the length direction of the second parallel guide rail 601 of the sampling bottle and is located above the second parallel guide rail 601 of the sampling bottle. Figure 16As shown, the longitudinal movement unit includes two horizontal slide rails 603 arranged along the length of the second parallel guide rail 601 for the sampling bottle, a conveyor belt 604 parallel to the horizontal slide rails 603, a tidying motor 605 drivingly connected to the conveyor belt 604, an L-shaped connector 606 fixed to the conveyor belt 604, and a sliding connection block 607 slidably mounted on the horizontal slide rails 603. In this embodiment, each conveyor belt 604 is fixed with an L-shaped connector 606, and each horizontal slide rail 603 is equipped with two sliding connection blocks 607.

[0129] The push unit 602 is connected to the L-shaped connector 606 and the sliding connection block 607. When the adjustment motor 605 drives the conveyor belt 604, the conveyor belt 604 drives the push unit 602 to move longitudinally along the horizontal slide rail 603. Of course, depending on the situation, the longitudinal movement unit can also adopt a linear drive structure that combines a ball screw and a motor as known in the art.

[0130] like Figure 17 As shown, the pushing unit 602 includes a mounting base 608, a rotating component 609, and a pushing component. The mounting base 608 is connected to the L-shaped connector 606 and the sliding connection block 607 via a profile; the rotating component 609 is fixed on the mounting base 608, with the power output end facing downward, and is a rotary motor in the prior art; the pushing component includes a sliding frame 610 assembled on the power output end of the rotating component 609, two electric push rods 612 assembled on the sliding frame 610 and in an eight-shaped shape, and a push plate 613 assembled on the output end of the electric push rods 612. Figure 17 As shown, guide grooves 611 are provided on both sides of the sliding frame 610, and the output ends of the two electric push rods 612 are respectively limited in one of the guide grooves 611. When the two electric push rods 612 are synchronously extended and retracted, they can drive the push plate 613 to move along the guide groove 611.

[0131] When working, the longitudinal moving unit drives the pushing unit 602 to move toward the entrance of the second parallel guide rail 601 of the sampling bottle. At this time, the pushing plate 613 is located on the left side. Figure 16 When the push unit 602 reaches the entrance of the sampling bottle second parallel guide rail 601, the rotating member 609 drives the push member to rotate 180 °, so that the push plate 613 is located on the right side, reference Figure 17 The direction of the middle push plate 613; then the electric push rod 612 drives the push plate 613 to move, so that the push plate 613 contacts the rotary sampling bottle collection rack 6 located at the entrance of the second parallel guide rail 601 for the sampling bottle; finally, the longitudinal moving unit drives the pushing unit 602 to move toward the end of the second parallel guide rail 601 for the sampling bottle, and at this time the push plate 613 can push the rotary sampling bottle collection rack 6 from the entrance to the end.

[0132] (4) One-way toggle rotation module 22

[0133] This embodiment also includes a one-way toggle rotation module 22 installed at the filling station, which is used to one-way switch the sampling bottles in the rotary sampling bottle collection rack 6, so that all the sampling bottles in the rotary sampling bottle collection rack 6 can be filled and packaged at the filling station.

[0134] It should be noted that the filling stations described in this embodiment refer to the space between the triangular base plate 10 and the semicircular guide rail 501 for the sampling bottle.

[0135] like Figures 18 to 20 As shown, the one-way toggle rotation module 22 includes a rotating base 701, a one-way toggle assembly, a rotating slider 702, a movable slider 703, and a lever assembly 704. The rotating base 701 is fixed on the triangular base plate 10; the one-way toggle assembly is rotatably assembled on the rotating base 701 through a tapered roller bearing; the rotating slider 702 is connected to the top of the one-way toggle assembly through a spline to realize the rotation assembly on the rotating base 701. Figure 20 As shown, two opposite positioning posts 705 are provided on the side wall of the rotating slider 702; the movable slider 703 is assembled on the rotating base 701 by sliding up and down, as shown in FIG. Figure 20 As shown, two opposing inclined slots 706 are provided on the sidewall of the movable slider 703. The movable slider 703 is sleeved onto the rotating slider 702, and the positioning posts 705 on the sidewall of the rotating slider 702 are retained in the inclined slots 706 of the movable slider 703. When the movable slider 703 rises and slides on the rotating base 701, the positioning posts 705 and the inclined slots 706 act to drive the rotating slider 702 to rotate, thereby driving the one-way toggle assembly to swing.

[0136] The lever assembly 704 includes a lever base fixed on the triangular base plate 10 and a lever rotatably mounted on the lever base. Figure 18 As shown, the first end of the lever is connected to the sampling bottle capping device 309, and the second end is connected to the movable slider 703. When the sampling bottle capping device 309 is driven by the capping assembly to ascend, the movable slider 703 is moved down along the rotating base 701 by the action of the lever assembly 704; when the sampling bottle capping device 309 is driven by the capping assembly to descend, the movable slider 703 is moved up along the rotating base 701 by the action of the lever assembly 704.

[0137] Furthermore, the first end of the lever is connected to the sampling bottle capping device 309 by magnetic adsorption, and the second end is connected to the movable slider 703 by a ball joint connection.

[0138] The one-way toggle assembly corresponds to the sampling bottle located below the telescopic water outlet 203 in the rotary sampling bottle collecting rack 6, such as Figure 20As shown, the one-way toggle assembly includes a rotating column 707 for spline connection with the rotating slider 702 and a plurality of toggle plates 708 mounted on the rotating column 707. The plurality of toggle plates 708 are plate-shaped structures, and each adjacent two toggle plates 708 are hinged together by a one-way hinge seat. Each one-way hinge seat is provided with a return spring for returning the toggle plate 708. Figure 20 As shown, when the one-way dial plate 708 assembly swings counterclockwise, multiple dial plates 708 form a plate-like structure with a certain strength, and at this time the sampling bottle can be driven to rotate clockwise in the rotary sampling bottle collection rack 6; when the one-way dial plate 708 assembly swings clockwise, multiple dial plates 708 form a flexible structure, and at this time no force can be applied to drive the sampling bottle to rotate counterclockwise in the rotary sampling bottle collection rack 6.
