Abstract
Description
Technical Field
[0001] This application relates to the field of water quality monitoring technology, and more specifically, to a water quality sampler with location identification. Background Technology
[0002] Water quality monitoring, as an important component of the environmental monitoring system, plays a crucial role in assessing the degree of water pollution, tracing pollution sources, and formulating remediation strategies. In existing technologies, water samplers have internal supports for holding sample bottles, with varying numbers depending on their size. Water is introduced into the sample bottles through the inlet structure, and drained through the outlet structure.
[0003] However, in existing samplers, the sample bottle is not always correctly placed after being inserted. Operational errors can lead to incorrect sample placement, or the absence of a sample bottle at the corresponding location on the inlet structure, resulting in invalid sample injection or sample confusion, severely impacting the reliability of monitoring data. Furthermore, existing equipment relies heavily on manual recording of sample information, making traceability management of the sampling process difficult, especially in multi-point, high-frequency sampling scenarios, where operational oversights can easily lead to errors in data-sample correspondence. Utility Model Content

[0044] Please refer to Figures 1 to 11 An embodiment of this application provides a water quality sampler 100 with location recognition, comprising:
[0045] Base 10, and sensor 11 is provided on base 10;
[0046] The sample holder 20 is rotatably mounted on the base 10. The sensor 11 is used to detect the rotation stroke of the sample holder 20. By detecting its rotation stroke, the stroke of the sample holder 20 can be calibrated and positioned. The sample holder 20 has multiple sample slots for placing sample bottles L.
[0047] The sample feeding and discharging mechanism 30 has a working area, which is used for feeding or discharging samples into the sample bottle L on the sample holder 20.
[0048] The detection assembly includes a detection element 40 and a trigger element. The detection element 40 is located near the working area of the sample feeding and discharging mechanism 30, and the trigger element is located on the sample retention bottle L.
[0049] The control system determines whether there is a sample bottle L in the working area of the sample feeding and discharging mechanism 30 based on the information fed back by the detection element 40, determines whether the sample bottle L is aligned based on the information fed back by the sensor 11, and controls the sample feeding and discharging mechanism 30 to work or reset when there is a sample bottle L.
[0050] In short, the detection component can help determine whether a sample bottle L is present, avoiding sample injection failure when there is no sample bottle L. Together with the sensor 11, it can more accurately locate the position of the sample bottle L, ensuring that the sample bottle L is accurately located in the working area when it is present. This avoids sample overflow during the injection process due to deviation in the position of the sample bottle L, and further avoids deviation in the sampler's sample retention data.
[0051] In this embodiment, a geared motor 52 is connected to the bottom of the sample holder 20 via a coupling 51. The housing of the geared motor 52 is connected to the base 10. The geared motor 52 controls the bottle position using pulse technology, driving the sample holder 20 to rotate a preset stroke according to the instructions of the control system. The sample holder 20 has structural contacts. When the sensor 11 detects the position of the contact, the sample bottle L in the working area of the sample feeding and discharging mechanism 30 is bottle number 0, thus confirming that the sample bottle L has been rotated into position. In some embodiments, the detection element 40 is a photoelectric switch, and the sample bottle L itself acts as a trigger. When a sample bottle L is present, the photoelectric switch is triggered, and the control system can know that a sample bottle L is in the working area; if no sample bottle L is present, the photoelectric switch cannot be triggered.
[0052] In some embodiments, there are multiple triggers, each with a unique serial number, and each sample bottle L has a unique serial number. This allows for the identification of the specific sample bottle L upon detection, preventing incorrect placement of the wrong sample bottle L in the designated sample compartment due to operator error (e.g., placing bottle 11 in the compartment intended for bottle 7), thus avoiding any impact on water quality monitoring due to incorrect sample placement.
[0053] Furthermore, each trigger is equipped with a QR code as a unique identifier;
[0054] After the control system controls the sample feeding and discharging mechanism 30 to feed samples into the sample bottle L, it can record that the sample bottle L corresponding to the QR code has been sampled; after discharging the sample bottle L, it can record that the sample bottle L corresponding to the QR code has been discharged.
[0055] Understandably, in addition to being numbered, the trigger using QR codes can also record other information, which is then identified by the detection device 40 and provided to the control system. This enables richer labeling of water samples. For example, QR codes can be created before sampling based on different sampling locations and then fixed to the sample bottles L. The control system can then read where some sample bottles L were sampled and where others were sampled. This makes it easier for different personnel to collect samples into the corresponding sample bottles L, and also facilitates the collection of water samples from the water area to be analyzed during the analysis phase, thereby maximizing the accuracy of the sampling operation.
[0056] In this application, the sample feeding and discharging mechanism 30 includes a base 31, a linear drive mechanism 32, a light rod 33, a position detector 34, a sample feeding component 35, and a sample discharging component 36;
[0057] A base 31 is mounted on a base 10. A light rod 33 is slidably mounted on the base 31. A position detector 34 is mounted on the base 31 and can detect the position of the light rod 33. A sample injection component 35 is mounted on the upper end of the light rod 33, and a sample dispensing component 36 is mounted on the lower end of the light rod 33. The area between the sample injection component 35 and the sample dispensing component 36 is the working area. The output end of a linear drive mechanism 32 is connected to the light rod 33 and can drive the light rod 33 to rise and fall. In this embodiment, a push rod motor is used as the linear drive mechanism 32.
[0058] The optical rod 33 is connected to the linear drive mechanism 32 by a connecting plate 37. The position detector 34 can detect the position of the connecting plate 37 to determine the height of the optical rod 33. When sample injection or discharge is not required, the position detector 34 can detect that the connecting plate 37 is in the zero position. At this time, the sample holder 20 can rotate without interfering with the sample injection component 35 or the sample discharge component 36.
[0059] In this embodiment, the detection element 40 is positioned on the base 31 and close to the working area, allowing for close-range detection of the presence of the sample bottle L. It also identifies the specific numbering information when the sample bottle L has a unique number.
[0060] Specifically, the sample introduction component 35 includes a sample introduction nozzle 351 and an addition module 352. The sample introduction nozzle 351 and the addition module 352 are connected. The sample introduction nozzle 351 is used to introduce samples into the sample bottle L, and the addition module 352 is used to add reagents to the sample introduction nozzle 351. Furthermore, the sample introduction nozzle 351 has a hollow structure; the upper end can be connected to a water inlet pipe, and the lower end can be inserted into the valve port of the sample bottle L. When the addition module 352 is present, the sample introduction nozzle 351 also has an opening in the middle. The addition module 352 has an addition port 3521, which is connected to the opening. Reagents such as fixatives can be added through the addition port 3521 according to the reagent sampling requirements.
[0061] The water quality sampler 100 with positioning recognition includes multiple sample bottles L, each sample bottle L having an upper valve port L1 and a lower valve port L2. The valve port of the sample bottle L has a sealing component L3, which seals the valve port when there is no external force and can be opened when the sealing component L3 is pressed. The specific structure can be referred to as the valve port and sealing component L3 of a typical sample bottle L, and will not be described in detail here.
[0062] The arrangement component 36 is a push rod or push pin, which can be used to open the valve's sealing component L3.
[0063] When the linear drive mechanism 32 drives the sample injection component 35 downward, it can open the upper valve port L1 for sample injection; when the linear drive mechanism 32 drives the sample discharge component 36 upward, it can open the lower valve port L2 for sample discharge. The water quality sampler 100 with positioning recognition also includes a drainage trough 60, which is disposed on the base 10 and below the sample discharge component 36.
[0064] The principle of this embodiment is:
[0065] The operator can place a certain number of sample bottles L according to sampling needs. For example, the sample holder 20 in this embodiment has 25 sample slots, so it can be filled to the brim, or only a few or a dozen can be placed, depending on the needs. The sample holder 20 has a bottle position mark 0, into which the 0 sample bottle L is placed for cleaning the tubing.
[0066] During sample injection, the sample holder 20 will rotate to allow the zero bottle to enter the working area of the sample injection and discharge mechanism 30. The sensor 11 of the base 10 will provide feedback on whether the sample slot corresponding to the zero sample bottle L has sufficient travel. The detection element 40 will determine whether the sample bottle L is indeed in place at this time, ensuring that the injection nozzle 351 is aligned with the valve of the bottle.
[0067] The linear drive mechanism 32 pushes the inlet nozzle 351 downwards, causing the water sample to flush the nozzle and prevent impurities from affecting the sample. Then, the sample holder 20 rotates again, allowing the sample bottle L to enter the working area. The sample inlet / outlet mechanism 30 then pours the water sample into the sample bottle L. If the sample bottle L has a unique number, the detection element 40 will check the number upon entering the working area to prevent incorrect numbering. Furthermore, the detection element 40 will issue an alarm if it detects no bottle or an incorrect number, alerting the operator to prevent damage to the sampler's internal components if no bottle is found.
[0068] When a new water sample needs to be injected, first rotate bottle 0 into position, then rinse the injection nozzle 351 with the new water sample, and then rotate the new sample bottle L over for injection.
[0069] For the sample bottle L that needs to be sorted, the above positioning steps can be repeated, and then the linear drive mechanism 32 drives the sorting component 36 to the top.
[0070] In summary, the water quality sampler 100 with positioning recognition of this application, through the cooperation of the sensor 11 and the detection component, can accurately deliver the sample bottle L to the working area, avoiding the impact of water sample collection due to the sample bottle L being placed in the wrong sample slot, and also avoiding damage to the sampler's internal components, thus improving existing problems.
[0071] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
