[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Please refer to Figures 1 to 8This utility model provides a technical solution: an online algae monitoring instrument self-calibration sampling device, including a monitoring platform 1. Each of the four corners of the monitoring platform 1 is threaded with an adjusting stud 2 that runs vertically through the platform. The bottom of each of the four adjusting studs 2 is rotatably fitted with a pad 3. A sample storage box 4 is provided above the monitoring platform 1. A closing component 5 is provided between the sample storage box 4 and the monitoring platform 1. A controller 7 is fixedly installed above the monitoring platform 1. A sampling tube 10 is fixedly connected to the bottom of the monitoring platform 1. A first pump body 11 is fixedly installed above the monitoring platform 1. The outlet end of the sampling tube 10 is fixedly connected to the inlet of the first pump body 11. A sample delivery tube 12 is fixedly connected to the outlet of the first pump body 11.

[0027] In this embodiment, the sample storage box 4 has multiple storage chambers 14. The outlet end of the sample delivery tube 12 is fixedly connected to a sample outlet frame 13 that communicates with it and is located above the sample storage box 4. The outlet of the sample outlet frame 13 corresponds to the inlet of the multiple storage chambers 14 of the sample storage box 4. A servo motor 6 is fixedly installed in the groove on the upper side of the monitoring platform 1. A sliding groove 21 is opened downward on the upper side of the monitoring platform 1. The output shaft of the servo motor 6 is fixedly connected to a screw 8 that passes through the sliding groove 21. A slider 9 is fixedly connected to the bottom of the sample storage box 4, which slides in the sliding groove 21 and is threadedly engaged with the screw 8. A calibration device is fixedly connected to the top of the monitoring platform 1. The calibration liquid tank 15 and the waste tank 16 are respectively equipped with a second pump body 18 that is connected to the opening of the outer wall of the calibration liquid tank 15 and the waste tank 16. The ports of the two second pump bodies 18 are respectively connected to the connecting hoses 17 that are connected to the sample storage box 4. The connecting hoses 17 on the waste tank 16 are respectively connected to multiple waste outlets 19 that are connected to it and located in multiple storage chambers 14. The connecting hoses 17 on the calibration liquid tank 15 are respectively connected to multiple calibration liquid inlets 20 that are connected to it and located in multiple storage chambers 14. The controller 7 is electrically connected to the servo motor 6, the first pump body 11 and the second pump body 18 respectively.

[0028] Specifically, during sampling, the controller 7 sends a start signal to the first pump body 11. The first pump body 11 uses the negative pressure formed by the sampling tube 10 to extract the external water sample and transport it to the sample outlet frame 13 through the sample delivery tube 12. Since the sample outlet of the sample outlet frame 13 corresponds to the inlet of the multiple storage chambers 14 of the sample storage box 4, the water sample flows smoothly into the storage chambers 14. The controller 7 controls the servo motor 6 according to the set program. The output shaft of the servo motor 6 rotates, driving the screw 8 that passes through the slide groove 21. The screw 8 and the slider 9, which is fixed at the bottom of the sample storage box 4 and slidably engaged in the slide groove 21, form a threaded transmission. The controller 7 moves the slider 9 within the groove 21, thereby driving the sample storage box 4 to move and precisely adjust the relative positions of each storage chamber 14 and the sample outlet of the sample outlet frame 13, so as to achieve on-demand distribution of water samples. During self-calibration, the controller 7 first controls the second pump body 18 on the outer wall of the calibration liquid tank 15 to start, injecting the calibration liquid into the storage chamber 14 through the connecting hose 17 and the calibration liquid inlet 20 to calibrate the device. After calibration, the controller 7 then controls the second pump body 18 on the outer wall of the waste tank 16 to start, drawing the waste liquid and impurities into the waste tank 16 through the connecting hose 17 and the waste outlet 19 to complete the calibration process.

[0029] In this embodiment, the closing component 5 includes a vertical strip 501 fixedly connected to the upper side of the monitoring platform 1 and located on one side of the sample storage box 4. The sample storage box 4 has a plurality of through slots 502 corresponding to the storage chamber 14 on one side. A beveled abutment plate 506 is fixedly connected to the side of the connecting block 504 facing the vertical strip 501. An abutment strip 503 is slidably fitted on the inner wall of the through slot 502. A connecting block 504 is fixedly connected to the side of the abutment strip 503 facing the vertical strip 501. A spring 505 is fixedly connected between the connecting block 504 and the outer side of the sample storage box 4. A placement slot 507 is opened on one side of the inner wall of the storage chamber 14. A closing plate 508 corresponding to the opening of the storage chamber 14 is slidably fitted in the placement slot 507. A beveled block 509 that overlaps with the abutment strip 503 is fixedly connected to the bottom of the closing plate 508.

[0030] Specifically, when the sample storage box 4 moves, the upright bar 501 fixed on the upper side of the monitoring platform 1 presses against the inclined abutment plate 506 on the connecting block 504, pushing the connecting block 504 and the abutment bar 503, which is slidably engaged in the through groove 502, to move against the elastic force of the spring 505. The abutment bar 503 pushes the inclined block 509 to make the closing plate 508, which is slidably engaged in the placement groove 507, slide, opening the opening of the storage chamber 14. After the sample storage box 4 is moved away, the spring 505 resets and drives the abutment bar 503, and the inclined block 509 pulls the closing plate 508 to close the storage chamber 14, ensuring sample safety.

[0031] When the device is in use, the entire device immediately enters the working state when the monitoring command is issued via the controller 7. The first pump body 11 responds first, drawing up the external water sample through the sampling tube 10. The water sample flows into the sample outlet frame 13 along the sample delivery tube 12, and is then precisely guided by the sample outlet frame 13 to the multiple storage chambers 14 of the sample storage box 4. Immediately afterwards, the servo motor 6 starts to run, and its output shaft drives the screw 8 to rotate. The slider 9, which is threaded with the screw 8, slides in the slide groove 21, thereby pushing the sample storage box 4 to move, so that each storage chamber 14 is aligned with the sample outlet frame 13 in turn, completing the distribution and storage of the water sample. During this process, the closing component 5 plays a role simultaneously. When the sample storage box 4 moves, the vertical bar 501 presses against the inclined abutment plate 506, causing the connecting block 504 to drive the abutment bar 503 to overcome the spring. The resistance of spring 505 slides within the through groove 502, and the abutment bar 503 pushes the inclined block 509, causing the closing plate 508 to slide within the placement groove 507, opening the storage chamber 14 to receive water samples. After the sample storage box 4 is removed, the elastic force of spring 505 causes the abutment bar 503 to reset, driving the closing plate 508 to close the opening of the storage chamber 14, preventing sample contamination. When calibration is required, controller 7 controls the second pump body 18 on the outer wall of calibration liquid tank 15 to start, injecting calibration liquid into storage chamber 14 through connecting hose 17 and calibration liquid inlet 20. After calibration, the second pump body 18 on the outer wall of waste tank 16 is opened, pumping calibration waste liquid and impurities in storage chamber 14 to waste tank 16 through connecting hose 17 and waste outlet 19, completing the self-calibration process and preparing for the next monitoring.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
