[0024] The following is combined with Figure 1-7 This application is described in further detail.

[0025] Reference Figure 1 The flexible structure multi-parameter water quality detection device includes a body 1, a sample box 11, a test tube rack 12, a switch cover mechanism 2, a liquid separation mechanism 3, a liquid adding mechanism 4, a detection mechanism 5, a robotic arm 6 and a control module.

[0026] The machine body 1 is provided with a workbench. The sample box 11 is a box-shaped structure, and multiple sample bottles are placed inside. The upper surface of the sample box 11 has multiple openings for the sample bottles to extend out. The workbench is provided with a sample area for placing the sample box 11. The test tube rack 12 has a disc-shaped cross-section, and the test tubes placed inside are divided into inner and outer layers along the radial direction of the test tube rack 12. The test tubes in each layer are arranged along the circumference of the test tube rack 12. The workbench has a test tube area for placing the test tube rack 12.

[0027] The cover opening and closing mechanism 2 is arranged on the side of the sample area away from the workbench operating surface, and is used to open and close the bottle caps of the sample bottles; the liquid separation mechanism 3 is arranged on one side of the test tube area, and is used to absorb and discharge the liquid in each sample bottle into the test tube on the test tube rack 12; the liquid adding mechanism 4 is arranged on the side of the test tube area away from the sample area, and is used to add required reagents to the test tubes on the test tube rack 12 as needed; the detection mechanism 5 is arranged on the body 1, and is used to perform static color development and spectroscopic detection processing on the solution in the test tube; the robotic arm 6 is arranged in the middle of the body 1, and is used to transfer the test tube rack 12 to each designated position. The robotic arm 6 can be realized by using existing technology according to the functions described in this article, and will not be repeated here; the control module is electrically connected to the cover opening and closing mechanism 2, the liquid separation mechanism 3, the liquid adding mechanism 4, the detection mechanism 5 and the robotic arm 6 respectively.

[0028] Among them, the control module is configured as follows: Upon receiving sample information and test tasks input by the user (sample information such as sample source, sampling time, sampling volume, etc., and test tasks such as total nitrogen data or ammonia nitrogen data in the test liquid and other parameter data), data analysis is performed based on the sample information and test tasks (for each sample information and corresponding test task, the required operation steps and the amount of reagents required to be added in the steps, etc.); According to the analysis results, execution parameters for controlling the switch cover mechanism 2, the liquid dispensing mechanism 3, the liquid adding mechanism 4, the detection mechanism 5 and the robot arm 6 are generated respectively (such as which mechanisms need to be involved in each detection step and the corresponding movement amount), and based on each execution parameter, the corresponding switch cover mechanism 2, the liquid dispensing mechanism 3, the liquid adding mechanism 4, the detection mechanism 5 and the robot arm 6 are controlled to respond.

[0029] Through the above settings, each manual detection step is converted into multiple operation modules, and multiple operation modules are integrated into one. The modular integrated design replaces the traditional method of relying on manual labor to detect multiple parameters in water quality, thereby improving the overall detection efficiency and accuracy.

[0030] Reference Figure 2In order to place more sample boxes 11 in the sample area for more timely testing, multiple sample boxes 11 are provided and stacked up, and positioning rods are fixed at the four corners of the upper end of each sample box 11. Positioning grooves for the positioning rods are provided at the four corners of the lower end of the sample box 11, so that the stacking of multiple sample boxes 11 is more stable and prevents collapse.

[0031] The body 1 is located below the workbench and has space reserved for stacking multiple sample boxes 11 and is provided with a pallet 13. Multiple untested sample boxes 11 are stacked on the pallet 13. The body 1 is located on one side of the pallet 13 and is provided with a receiving plate 14 for stacking the sample boxes 11 after sampling. The body 1 is provided with a transfer mechanism for transferring the sample boxes 11 after sampling to the receiving plate 14 and stacking them in sequence.

[0032] The transfer mechanism includes a lifting assembly 1 for lifting the pallet 13, a moving assembly 72 for laterally moving the sample box 11, from which the topmost layer of samples has been taken, to the receiving plate 14, and a lifting assembly 2 for lifting the receiving plate 14. The lifting assembly 1 includes a lifting screw, a limiting rod, and a lifting motor. The lifting screw is rotatably connected to the body 1. The lifting screw is threadably connected to a lifting nut, which is fixedly connected to the pallet 13. The limiting rod is fixedly connected to the body 1 and parallel to the lifting screw. One end of the pallet 13 is slidably connected to the limiting rod. The lifting motor is fixedly connected to the inner wall of the body 1, and the lifting motor drives the lifting screw to rotate via a synchronous wheel structure, thereby achieving the lifting and lowering of the pallet 13. The structure of the lifting assembly 2 is consistent with that of the lifting assembly 1, enabling the receiving plate 14 to be raised and lowered, so the detailed description will not be repeated.

[0033] Reference Figure 2 and Figure 3 The moving component 72 includes a linear motor 721, a guide rail 722, a translation plate 723 and a plug-in component 73. The linear motor 721 is fixedly connected to the workbench and is located on one side of the sample box 11. The guide rail 722 is fixed to the upper surface of the workbench. The translation plate 723 is slidably connected to the guide rail 722, and one end of the translation plate 723 is fixedly connected to the moving part of the linear motor 721, so that the linear motor 721 can drive the translation plate 723 to move along the guide rail 722.

[0034] The plug-in assembly 73 includes a plug-in cylinder 731 and two plug-in rods 732. The plug-in cylinder 731 is fixed on the upper surface of the translation plate 723. The output shaft of the plug-in cylinder 731 is perpendicular to the side wall surface of the sample box 11, and the output shaft of the plug-in cylinder 731 is perpendicular to the guide rail 722. The output shaft of the plug-in cylinder 731 is fixedly connected to a vertical connecting plate 733. The connecting plate 733 is parallel to the sample box 11. The two plug-in rods 732 are perpendicular and fixedly penetrated at both ends of the connecting plate 733, and the translation plate 723 is located on both sides of the plug-in cylinder 731 and is fixedly connected with guide blocks 734 respectively. The end of the plug-in rod 732 facing away from the sample box 11 slides through the guide block 734. A plug hole 735 is provided through the side wall of the sample box 11 facing the plug rod 732. The plug rod 732 can be inserted into the plug hole 735 by being driven by the plug cylinder 731. In order to enable the plug rod 732 to support the sample box 11 more stably, a card groove is provided along the circumference of one end of the plug rod 732 inserted into the plug hole 735. An arc-shaped hole is connected and extended upward on the upper edge of the plug hole 735. The diameter of the arc-shaped hole is smaller than the diameter of the plug hole 735, so that after the plug rod 732 is inserted into the plug hole 735, the card groove is engaged with the edge of the arc-shaped hole.

[0035] With the above arrangement, when the support plate 13 is at the lowest position, the sample box 11 on the uppermost layer extends out of the workbench surface, and the insertion hole 735 on the sample box 11 is aligned with the insertion rod 732. When the sample box 11 on the uppermost layer has been sampled, the plug cylinder 731 drives the connecting plate 733 to move, so that the insertion rod 732 is inserted into the plug hole 735, thereby being fixed relative to the sample box 11. Then the linear motor 721 drives the translation plate 723 to move toward the direction close to the receiving plate 14, and the sample box 11 is placed on the receiving plate 14. The plug cylinder 731 is pressed again. The linear motor 721 is reset; at this time, the lifting component 1 moves the pallet 13 upward, so that the next layer of sample boxes 11 is located at the top layer. If it is necessary to transfer the sample box 11 located at the top layer of the pallet 13, the lifting component 2 will lower the receiving plate 14, thereby driving the sample box 11 previously transferred to the receiving plate 14 to move down to make room, and then repeat the above steps. The next sample box 11 can be stacked on the previous sample box 11, and so on, to complete the work of transferring and stacking all the stacked sample boxes 11 on the pallet 13 to the receiving plate 14.

[0036] Reference Figure 1In another embodiment of the present application, the liquid dispensing mechanism 3 includes a second robotic arm 31, a liquid collection needle 32, a cleaning tool 33, and a pneumatic system. The second robotic arm 31 is installed on a workbench. The end of the second robotic arm 31 is fixed to the liquid collection needle 32. The liquid collection needle 32 is vertically arranged. The pneumatic system is arranged in the body 1 and is fixedly connected to the top of the liquid collection needle 32 through a hose. The pneumatic system provides power for the liquid collection needle 32 to absorb and discharge liquid. In order to prevent cross contamination, the cleaning tool 33 is fixedly embedded in the workbench and is located on one side of the second robotic arm 31. The cleaning tool 33 is used to rinse the liquid collection needle 32. The cleaning tool 33 is arranged in a bucket shape and has a cleaning groove for the liquid collection needle 32 to be inserted in the longitudinal direction. A cleaning nozzle is installed at the bottom of the cleaning groove. Therefore, a water pump and a water tank are provided in the body 1. The water pump is connected to the water tank and the cleaning nozzle of the cleaning tool 33 respectively. By controlling the water pump, water passes through the cleaning nozzle to rinse the inner wall and the outside of the liquid collection needle 32 to prevent cross contamination.

[0037] The moving range of the second robotic arm 31 can cover the movement of the liquid collection needle 32 between the sample box 11, the test tube rack 12 and the cleaning tool 33. The second robotic arm 31 can be implemented using existing technology, so it will not be described here in detail.

[0038] Reference Figure 4 The liquid adding mechanism 4 includes a steering motor 41, a swing arm 42, a liquid adding tray 43, multiple liquid adding heads 44, and a shaking motor 45. The swing arm 42 is rotatably connected to the workbench via a bearing. The steering motor 41 is mounted on the lower surface of the workbench and has an output shaft fixed to the swing arm 42, which is used to drive the swing arm 42 to swing back and forth along the horizontal plane. The swing end of the swing arm 42 is fixedly connected to a vertical central axis, the lower end of which is connected to the liquid adding tray 43. Multiple liquid adding heads 44 are arranged at intervals along the circumference of the liquid adding tray 43. The liquid adding heads 44 are connected to a reagent reservoir preset in the body 1 via a hose. The reagent reservoir provides a power source for pumping reagents to the liquid adding heads 44.

[0039] The workbench features a liquid-adding tank for the test tube rack 12. A shaker motor 45 is fixed to the workbench below the liquid-adding tank. The tank is rotatably connected to a horizontal turntable (not shown) via a bearing. The output shaft of the shaker motor 45 faces upward and extends out of the liquid-adding tank, coaxially fixed to the turntable. A protrusion extends upward from the center of the turntable to position the test tube rack 12. The test tube rack 12 is placed on the turntable, and a groove is defined at the bottom of the test tube rack 12 for the protrusion to pass through.

[0040] Through the above arrangement, the steering motor 41 drives the swing arm 42 away from the top of the liquid adding tank, allowing a staff member to place the test tube rack 12 placed in the test tube area on the turntable in the liquid adding tank. In other embodiments, the test tube rack 12 can also be transferred by a robotic arm 6. The steering motor 41 is then controlled to drive the swing arm 42 to move, causing the liquid adding tray 43 to move above the liquid adding tank, so that each liquid adding head 44 is located above each test tube, and reagent is added to the test tube. The shaking motor 45 then drives the turntable to rotate to evenly shake the liquid in the test tube. In this embodiment, multiple test tube racks 12 are stacked from bottom to top in the test tube area, and the stacking method is consistent with the sample box 11. A lifting assembly 3 is also provided, which has the same structure as the lifting assembly 1. The stacked test tube racks 12 are raised and lowered by the lifting assembly 3, allowing the device to store multiple test tube racks 12, thereby improving utilization.

[0041] In another embodiment of the present application, since the test tubes in the test tube rack 12 are arranged in an inner layer and an outer layer, in order to enable the multiple liquid adding heads 44 arranged around the liquid adding tray 43 to add reagents to the test tubes in the outer layer after adding reagents to the test tubes in the inner layer without increasing the number of liquid adding heads 44, the arrangement is as follows: Reference Figure 4 and Figure 5 The swing arm 42 is fixedly connected to an adjustment motor 46, and the output shaft of the adjustment motor 46 is fixedly connected to an adjustment gear 47. The edge of the liquid adding tray 43 is provided with a tooth structure that meshes with the adjustment gear 47. The liquid adding tray 43 is rotatably connected to the central axis via a bearing. The liquid adding tray 43 is provided with a plurality of drive slots 48, and the plurality of drive slots 48 are evenly distributed along the circumference of the liquid adding tray 43. A horizontal fixed plate 49 is coaxially fixed to the central axis below the liquid adding tray 43. The fixed plate 49 is provided with a plurality of arc-shaped sliding slots 491, and the plurality of sliding slots 491 are evenly distributed along the circumference of the fixed plate 49. The number of drive slots 48 and sliding slots 491 is the same and corresponds to each other. A vertical sliding pin is provided in each drive slot 48 and sliding slot 491 for sliding movement. The drive slot 48 is a straight slot and extends in the opposite direction to the sliding slot 491. The liquid adding head 44 is fixedly connected to the lower end of the sliding pin.

[0042] Through the above-mentioned arrangement, when the adding head 44 has finished adding reagents to the test tubes located in the outer layer and it is necessary to add reagents to the test tubes located in the inner layer, the adjusting motor 46 is controlled to drive the adjusting gear 47 to rotate, thereby driving the adding plate 43 to rotate, so that the inner wall of the driving groove 48 applies a force to the sliding pin, so that the sliding pin can move along the sliding groove 491 toward the direction close to the central axis. At the same time, the sliding pin also moves along the driving groove 48 toward the direction close to the central axis, so that the sliding pin moves from the end of the sliding groove 491 farthest from the central axis to the end closest to the central axis. At this time, the adding head 44 is located above the test tubes in the inner layer, so that reagents can be added to the test tubes in the inner layer.

[0043] Reference Figure 1 In this embodiment, the cover opening and closing mechanism 2 can be a robot arm three, which is installed on the workbench, and a rotatable clamping claw is installed at the end of the robot arm three. By controlling the clamping claw at the end of the robot arm three, the clamping claw can achieve the functions of clamping and rotating, thereby realizing the operation of opening and closing the cover of the sample bottle. The robot arm three and the clamping claw can use existing technologies to achieve the above functions, so they are not described in detail.

[0044] Reference Figure 1 In this embodiment, the detection mechanism 5 can be a spectrophotometer using existing technology. The detection mechanism 5 is installed on a workbench, and a resting area for the test tube rack 12 to rest is provided on the side of the workbench located at the detection mechanism 5. A robotic arm 4 is installed on one side of the resting area, and a liquid pipetting needle is installed at the end of the robotic arm 4. The test tube rack 12 with the developer added is transferred to the resting area by the robotic arm 6 for resting. The liquid pipetting needle is then moved by the robotic arm 4 to aspirate the solution in the test tube after resting and discharge it into the detection port of the detection mechanism 5. The detection result is obtained through the detection of the detection mechanism 5. During this process, a cleaning component with the same structure and function as the above-mentioned cleaning tool 33 is also provided on the side of the workbench located at the resting area for rinsing the liquid pipetting needle. In this embodiment, a high-pressure steam digestion pot or centrifuge can also be placed in the body 1. According to the requirements of the detection task, the test tube rack 12 can be selectively transferred and placed by the robotic arm 6 to digest or centrifuge the liquid in the test tube.

[0045] In another embodiment of the present application, due to the above steps, only one sample box 11 can be transferred at a time. Considering that in special circumstances, it is necessary to immediately sample and test the sample boxes 11 located at the lower layer as needed, transferring them one by one is time-consuming. Therefore, it is necessary to be able to transfer multiple sample boxes 11 above the target sample box 11 at one time. Therefore, the plug-in assembly 73 can also be as follows: Reference Figure 6 and Figure 7 The plug-in assembly 73 includes a fixed plate 74, a drive assembly 8, and multiple horizontal telescopic rods 75. The fixed plate 74 is vertical and its top is fixedly connected to the translation plate 723. The fixed plate 74 is located on the side of the stacked sample boxes 11 away from the workbench operating surface. The multiple telescopic rods 75 are slidably installed in the fixed plate 74 in the horizontal direction and are arranged in the longitudinal direction. A support tube for the telescopic rods 75 is fixedly installed in the side wall of the sample box 11. The installation positions of the multiple telescopic rods 75 correspond to the positions of the support tubes of the stacked sample boxes 11. In this embodiment, in order to make the support tube more stable, a reinforcing rib is fixedly connected between the support tube and the inner wall of the sample box 11.

[0046] Reference Figure 6 and Figure 7 The drive assembly 8 includes a drive motor 81, a driving wheel 82, and multiple linkage assemblies 83. The drive motor 81 is fixedly connected to the upper end of the fixed plate 74, with its output shaft horizontal and coaxially fixed to the driving wheel 82. The number of linkage assemblies 83 is the same as the number of telescopic rods 75, and each linkage assembly 83 corresponds to each telescopic rod 75. They are used to connect with the driving wheel 82 and link the telescopic rods 75, so that the telescopic rods 75 can be moved through the corresponding support tubes.

[0047] The linkage assembly 83 includes a driven pulley 831, a timing belt 832, a linkage gear 833, and a drive pulley 834. The drive pulley 834 is rotatably connected to the side wall of the fixed plate 74 via a bearing. The telescopic rod 75 is externally threaded, and the drive pulley 834 is threadedly sleeved onto the exterior of the telescopic rod 75. A rotating shaft is rotatably connected to one side of the fixed plate 74 via a bearing. The linkage gear 833 is coaxially fixed to the rotating shaft. The drive pulley 834 is externally provided with a tooth structure that meshes with the linkage gear 833. The driven pulley 831 is coaxially fixed to the rotating shaft. The timing belt 832 connects the driving pulley 82 and the driven pulley 831. Since there are multiple linkage components 83, and thus multiple synchronous belts 832, the driving wheel 82 is provided with multiple belt grooves arranged along its axial direction for the synchronous belt 832 to be mounted. The number of belt grooves is consistent with the number of synchronous belts 832, and each belt groove is provided with a limiting belt 71 for preventing the synchronous belt 832 from slipping out. One end of the limiting belt 71 is fixedly connected to one side of the belt groove, and the other end is fixed to the other side of the belt groove. There is a distance between the limiting belt 71 and the synchronous belt 832, and it does not interfere with the movement of the synchronous belt 832.

[0048] Based on the above, it is necessary to control the telescopic rod 75 and the sample box 11 to be transferred to be relatively fixed according to needs. Not all driven wheels 831 need to rotate at the same time, so the fixed plate 74 is provided with multiple adjustment components 84 for adjusting the tension of each synchronous belt 832. It should be noted that the number of adjustment components 84 is consistent with the number of telescopic rods 75. Each adjustment component 84 adjusts the tension of a synchronous belt 832. When a telescopic rod 75 is required to be passed through the support tube of the sample box 11 at the corresponding position, the tightness of the synchronous belt 832 is adjusted by controlling the corresponding adjustment component 84, so that the synchronous belt 832 is tightly fitted between the active wheel 82 and the driven wheel 831, thereby driving the telescopic rod 75 to move horizontally into the support tube.

[0049] The driving motor 81 and the regulating assembly 84 are electrically connected to the control module respectively. The control module is configured as follows: 1) Numbering the positions of each adjustment component 84 and each stacked sample box 11 and establishing an association relationship; For example: the positions of the respective adjustment components 84 are numbered A, B, C, D... from top to bottom, and the positions of the stacked sample boxes 11 are numbered a, b, c, d... from top to bottom.

[0050] 2) Obtain the sample box 11 transfer request initiated by the user; 3) According to the transfer requirements of the sample box 11, the adjustment component 84 at the corresponding position of the sample box 11 to be transferred is controlled to tighten the synchronous belt 832; It is understood that, for example, the sample box 11 transfer requirement may be pre-set and require the user to input the location of the target sample box 11. For example, if the user inputs the location of the target sample box 11 (which needs to be sampled immediately) as c, then the sample boxes 11 located at a and b need to be transferred at once. Therefore, a corresponding association table needs to be stored in the database in advance, for example: If the target sample box 11 is at position b, the control adjustment component 84A is controlled to tighten the synchronous belt 832 (i.e., the sample box 11 at position a is moved away); If the target sample box 11 is at position c, the control adjustment components 84A and B are controlled to tighten the synchronous belt 832 (i.e., the sample boxes 11 at positions a and b are removed simultaneously); If the target sample box 11 is at position d, the control adjustment components 84A, B, and C will tighten the synchronous belt 832 (i.e., the sample boxes 11 at positions a, b, and c will be moved away simultaneously); 4) When receiving the feedback signal from the regulating component 84 after completing the corresponding instruction, the driving motor 81 is controlled to move.

[0051] Through the above arrangement, multiple sample boxes 11 can be transferred at one time according to user needs, thereby improving efficiency.

[0052] Reference Figure 6 and Figure 7The adjusting assembly 84 includes an adjusting cylinder 841 and an adjusting wheel 842. The adjusting cylinder 841 is fixedly connected to the side of the fixing plate 74 and the output shaft is horizontal. The output shaft of the adjusting cylinder 841 is fixedly connected to the wheel frame. The adjusting wheel 842 is rotatably connected to the wheel frame through a bearing. The adjusting wheel 842 can contact the surface of the synchronous belt 832, so that the adjusting cylinder 841 drives the adjusting wheel 842 to move toward the direction close to the synchronous belt 832, thereby enabling the adjusting wheel 842 to apply a force to the synchronous belt 832, so that the synchronous belt 832 can fit closely. The driving wheel 82 and the driven wheel 831 drive the driven wheel 831 to rotate, so that the linkage gear 833 rotates synchronously, thereby rotating the driving wheel 834, and finally moving the telescopic rod 75 toward the corresponding sample box 11, and passing through the support tube of the sample box 11, thereby lifting the sample box 11; if multiple telescopic rods 75 move, multiple sample boxes 11 will be lifted at the same time, and multiple sample boxes 11 will be transferred to the receiving plate 14 at one time, so that the target sample box 11 can be located in the top position on the drag plate in time, which is convenient for detection.

[0053] It should be noted that since the length of the fixed plate 74 is set according to the total height of the stacked multiple sample boxes 11, and the fixed plate 74 will also be driven by the linear motor 721 to produce lateral movement, in order not to interfere with the connection between the pallet 13 and the lifting component one and the connection between the receiving plate 14 and the lifting component two, when implementing the plug-in component 73 of this embodiment, it is necessary to adjust the placement position of the lifting component one and the lifting component two, thereby adjusting the connection structure position between the pallet 13 and the receiving plate 14. The lifting component one and the lifting component two need to be set on the side of the pallet 13 and the receiving plate 14 close to the workbench operating surface or other positions that will not interfere with the lateral movement of the fixed plate 74.

[0055] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
