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, and are mainly responsible for collecting water samples from different water areas and layers. Although the water sampling devices in the prior art can automatically obtain water samples, they still rely heavily on manual operation in the filling, packaging and storage of sampling bottles, which not only leads to complex operations and low efficiency, but also reduces the degree of automation of the device, making it impossible 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, fill the water sample into the sampling bottle; then, seal the mouth of the sampling bottle; finally, properly store the sampling bottle and prepare it 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: 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 the sampling bottles. The second is that the human intervention process increases the probability of sample contamination, affecting the accuracy of water quality testing data; 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.

[0004] 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 costly, and still fail to fully solve the automation requirements for integrated filling, packaging, and storage of sampling bottles. In actual applications, 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, which solves the problem of automatic replacement and storage of sampling bottles, but fails to seal the sample bottles in time, resulting in difficulty in ensuring the effectiveness of the collected water samples.

[0005] Therefore, there is an urgent need for an automated water sampling device that can integrate the filling, packaging and storage functions of sampling bottles, which can reduce manual intervention while improving the efficiency and accuracy of water sample collection.

DETAILED DESCRIPTION

[0025] 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 used to limit the present invention.

[0026] This embodiment discloses a filling and packaging mechanism 4 for water sampling, such as Figures 1 to 7 As shown, the filling and packaging mechanism 4 for water body sampling includes an impeller module 7, an automatic filling module 8 and an automatic capping module 9.

[0027] A. Impeller module 7 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 5 As shown, the impeller module 7 includes a lifting base 101 fixedly mounted on a base plate, an impeller housing 102 fixedly mounted on the lifting base 101, and an impeller 103 rotatably mounted 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 thereof; a rotary power output shaft 106 is mounted at the center of the impeller 103 , and the rotary power output shaft 106 extends to the outside of the impeller housing 102 .

[0028] During operation, water sample enters the impeller housing 102 from the water inlet 104 , impacts the impeller 103 and then is 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 .

[0029] The above-mentioned substrate is used in the embodiment to integrate the impeller module 7, the automatic filling module 8 and the automatic capping module 9, and realize their assembly in the hull 1. In this embodiment, the substrate is a triangular substrate 10, and of course the substrate can also be set to a rectangular, trapezoidal or circular shape according to the situation.

[0030] B. Automatic filling module 8 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 .

[0031] The filling housing 201 is fixed on the triangular base plate 10 through a filling fixing base, and includes a lower housing 206 and an upper cover 207, wherein 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 housing 206 is provided with an outlet. The flow divider 202 is fixed in the filling housing 201, such as Figure 7 As shown, the flow divider 202 divides the inner cavity of the filling shell 201 into an upper chamber and a lower chamber; further, the flow divider 202 includes a transverse sealing plate 210 and a plug 211 fixed at the center of the transverse sealing plate 210, and 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, as shown in FIG. Figure 6 As shown, the telescopic water outlet 203 includes a ring plate 212 with a through hole and a water outlet pipe 213 fixed at the through hole of the ring plate 212. The shape and size of the ring plate 212 are adapted to the lower chamber; the inner diameter of the water outlet pipe 213 is adapted to the outer diameter of the plug 211, and the outer diameter of the water outlet pipe 213 is adapted to the diameter of the outlet of the filling shell 201. An O-ring 214 is provided at the outlet of the filling shell 201 to fit the outer wall of the water outlet pipe 213 to improve the sealing performance. In this embodiment, two O-rings 214 are provided.

[0032] 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.

[0033] The water pressure port 208 and the water discharge port 209 of the filling housing 201 are both connected to the upper chamber of the filling housing 201, and a valve 205 is provided on the water discharge port 209. In this embodiment, the valve 205 is a solenoid valve.

[0034] The return spring 204 is sleeved 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.

[0035] Based on the water pressure, the telescopic water outlet 203 can extend 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 applies pressure to 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, while 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.

[0036] It should be supplemented 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 size design ensures that only when the bottom end of the telescopic water outlet 203 extends into the mouth of the sampling bottle, the plug 211 will be separated from the telescopic water outlet 203, and the water sample can flow out from the telescopic water outlet 203. This design can effectively reduce the splashing of water during filling.

[0037] C. Automatic capping module 9 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.

[0038] Specifically, the bottle cap collector includes a cap storage bin 301 fixedly mounted on the triangular base plate 10 and a bottle cap guide rail 302 connected to the outlet of the cap storage bin 301, and the bottle cap guide rail 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 on the filling station. The bottle caps are stored in the cap storage bin 301 in a stacked form. Under the action of gravity, the bottle caps slide one by one from the outlet of the cap storage bin 301 along the bottle cap guide rail 302 to the cap outlet, and then fall from the cap outlet to the bottle mouth of the sampling bottle to be packaged.

[0039] 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 3As 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 rotating power output shaft 106 and is in transmission connection with the rotating 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 arranged 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 motion trajectory of the second end in the vertical direction. During operation, the rotating 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).

[0040] like Figure 4 As shown, a vertical slide rail 308 is also provided on the gland guide rail 306 along the vertical direction.

[0041] The sampling bottle capping device 309 is assembled on the vertical slide rail 308 of the capping guide rail 306 through a slider, and its position corresponds to the mouth of the sampling bottle on the filling station. The sampling bottle capping device 309 in this embodiment is an existing structure, which is connected to the second end of the transmission connecting rod 305, and is lifted and lowered along the vertical slide rail 308 under the drive of the transmission connecting rod 305 to realize automatic capping.

[0042] The water sampling filling and packaging mechanism 4 disclosed in this embodiment is used to realize automatic filling and packaging of the sampling bottle. The specific working process is as follows: 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 diverter 202 and the plug 211 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 port 209 is opened to discharge the water sample in the filling housing 201 from the drain port 209 to complete the pressure relief. Under the elastic force of the reset spring 204, the telescopic water outlet 203 moves upward to complete the reset.

[0043] Packaging: After the retractable water outlet 203 is reset, the sampling bottle needs to be transferred from below the retractable water outlet 203 to below the capping assembly (this embodiment is achieved by using the one-way toggle rotating module 22 described below). The rotary power output shaft 106 of the impeller module 7 provides rotary power for the capping assembly, and drives the sampling bottle capping device 309 to operate 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, so as to buckle the bottle cap at the cap outlet onto the bottle mouth of the sampling bottle below.

[0044] This embodiment also discloses a water body automatic sampling system, such as Figure 8 and Fig. 9 As shown, the automatic water sampling system comprises 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 above-disclosed structure.

[0045] The hull 1 includes a frame 2 and a shell covering the frame 2 for floating on the water.

[0053] The double-opening 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. Fig.13 and Fig.14As shown, the split-type switch door module includes a first split-type switch door 502, a second split-type switch door 503 and a vertical shaft transmission assembly 504. The first split-type switch door 502 is mounted at the entrance of the sampling bottle semicircular guide rail 501, and is used to control the input of the rotary sampling bottle collection rack 6; the second split-type switch door 503 is mounted at the exit of the sampling bottle semicircular guide rail 501, and is used to control the output of the rotary sampling bottle collection rack 6.

[0055] The left door 505 and the right door 506 both include a column and a door leaf that are fixedly connected together. The upper and lower ends of the column of the left door 505 are rotatably mounted on the gantry 2 through a support base 507, and the upper and lower ends of the column of the right door 506 are also rotatably mounted on the gantry 2 through a support base 507. In this embodiment, a torsion spring is provided in the support base 507 to return the door leaf to its original position after opening.

[0056] like Fig.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, wherein 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 ship frame 2 of the hull 1, and a fixed slider is slidably mounted on the fixed guide rail 512, and the fixed slider is rotatably connected to the middle part of the third link 510.

[0057] The action trigger assembly includes a paddle 513 and a toggle cam 514 corresponding to the paddle 513. The paddle 513 is fixed on the column of the left door 505 or the right door 506. In this embodiment, the paddle 513 is fixed on the column of the left door 505; the toggle cam 514 is rotatably assembled on the above-mentioned triangular base plate 10.

[0058] 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 connecting rod 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 from the paddle 513, under the action of the torsion spring of the supporting base 507, the left door 505 and the right door 506 rotate back to their original positions and are in a closed state.

[0059] The vertical shaft transmission assembly 504 is used to drive the toggle cam 514 to rotate. Fig.14 As shown, the vertical axis transmission assembly 504 includes an input shaft 515 transmission-connected to the rotating 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 transmission-connected to the output shaft 519, and a parallelogram transmission link 1 521 and a parallelogram transmission link 2 522 respectively hinged to the transmission crank 520 through a first end.

[0060] 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 through the L-shaped base 523, and the output shaft 519 is vertically arranged.

[0061] Further, such as Fig.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 .

[0062] When working, the vertical axis transmission assembly 504 converts the horizontal rotational force of the rotating power output shaft 106 into a vertical rotational force (achieved by the flipping movement of the Z-shaped transmission connecting rod 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 connecting rod 1 521 and the parallelogram transmission connecting rod 2 522.

[0063] (3) Full bottle storage module 21 The full bottle storage module 21 includes a second parallel guide rail 601 for sampling bottles and a push unit 602 mounted at the rear end of the hull 1 and the frame 2.

In this embodiment, each conveyor belt 604 is fixed with an L-shaped connector 606; each horizontal slide rail 603 is equipped with two sliding connection blocks 607.

[0065] 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 to move, the conveyor belt 604 drives the push unit 602 to move longitudinally along the horizontal slide rail 603. Of course, according to the situation, the longitudinal moving unit can also adopt a linear drive structure in which a ball screw and a motor cooperate in the prior art.

[0066] like Fig.17 As shown, the push unit 602 includes a mounting base 608, a rotating component 609 and a push component.

Fig.17As 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, the push plate 613 can be driven to move along the guide groove 611 .

[0067] 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. Fig.16 When the push unit 602 reaches the entrance of the sampling bottle second parallel 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 Fig.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 collecting 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 collecting rack 6 to move from the entrance to the end.

[0068] (4) One-way toggle rotation module 22 The present embodiment further comprises a one-way toggle rotating module 22 installed at the filling station, which is used for one-way switching of the sampling bottles in the rotary sampling bottle collecting rack 6, so that all the sampling bottles in the rotary sampling bottle collecting rack 6 can be filled and packaged at the filling station.

[0069] 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.

When the sampling bottle capping device 309 is driven by the capping assembly to ascend, the moving slider 703 descends along the rotating base 701 under the action of the lever assembly 704; when the sampling bottle capping device 309 is driven by the capping assembly to descend, the moving slider 703 ascends along the rotating base 701 under the action of the lever assembly 704.

[0072] Furthermore, the first end of the lever is connected to the sampling bottle capping device 309 by means of magnetic adsorption, and the second end is connected to the movable slider 703 by means of a ball joint connection.

[0073] The one-way toggle assembly corresponds to the sampling bottle located below the telescopic water outlet 203 in the rotary sampling bottle collection rack 6, such as Fig. 20 As 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, and each one-way hinge seat is provided with a return spring for returning the toggle plate 708.
