Abstract
Description
Technical Field
[0001] This utility model relates to the field of heavy metal detection technology, and in particular to a portable heavy metal detection device for aquatic products. Background Technology
[0002] Because aquatic products easily accumulate heavy metals such as lead, cadmium, mercury, and arsenic during their growth, these heavy metals can be transferred through the food chain and ultimately affect human health. Detecting the heavy metal content in aquatic products allows for the timely detection of heavy metal contamination issues, preventing products exceeding safety standards from entering the market and thus protecting consumer health.
[0003] Currently, portable heavy metal detection devices for aquatic products require the electrodes in the analysis cell to be coated before use. This involves sequentially adding pure water, electroplating solution, and pure water, followed by the detection of the target samples. During the detection process, it is necessary to perform blank testing, standard sample testing (sometimes standard sample testing twice), cleaning, testing the target sample, cleaning, testing the target sample, and so on, until all samples are tested. The entire detection process requires the testing personnel to be present at the scene (repeatedly opening and closing the analysis cell and repeatedly taking out sample cups), which is not only cumbersome and time-consuming but also reduces detection efficiency. Therefore, improvements are proposed. Utility Model Content

[0025] like Figures 1 to 4 As shown, a portable heavy metal detection device for aquatic products is disclosed, comprising an analyzer 1 and an analysis cell 2 electrically connected to the analyzer 1. A mounting bracket 3 is provided on one side of the analyzer 1, and a mounting groove 11 is formed in the top inner part of the mounting bracket 3. An electric slider is installed inside the mounting groove 11, and a housing 5 is fixedly connected to the movable end of the electric slider. The electric slider includes a first motor 8, which is fixedly embedded in the inner wall of one side of the mounting groove 11. A transverse screw 10 is fixedly connected to the drive end of the first motor 8, and the transverse screw 10 is rotatably connected to the inner wall of the mounting groove 11. The transverse moving screw 10 is connected to the mounting groove 11 via a bearing. The inner ring of the bearing is fixedly connected to the transverse moving screw 10, and the outer ring of the bearing is fixedly connected to the mounting groove 11. The outer surface of the transverse moving screw 10 is threaded with a slider body 9, and the slider body 9 is fixedly connected to the housing 5. The mounting groove 11 has a limiting function for the slider body 9, which can ensure the stability of the slider body 9's movement. The outer walls on both sides of the slider body 9 slide against the inner walls on both sides of the mounting groove 11. The mounting groove 11 has a limiting function for the slider body 9, which can ensure the stability of the slider body 9's movement.
[0026] A travel groove 17 is provided on one side of the outer surface of the housing 5. A lifting screw 15 is provided inside the travel groove 17. The lifting screw 15 is rotatably connected to the housing 5. The lifting screw 15 and the housing 5 are connected by a bearing. The inner ring of the bearing is fixedly connected to the lifting screw 15, and the outer ring of the bearing is fixedly connected to the housing 5. The lifting screw 15 extends through the inner top of the travel groove 17 to the inner side of the housing 5 and is installed together with the housing 5 with an electric gear drive assembly. The electric gear drive assembly includes a second motor 18, which is fixedly installed on one side of the inner wall of the housing 5. The driving end of the second motor 18 is fixedly connected to a driving bevel gear 13. A driven bevel gear 14 is meshed on one side of the outer surface of the driving bevel gear 13, and the driven bevel gear 14 is fixedly sleeved on the outer surface of the lifting screw 15. The cooperation between the driving bevel gear 13 and the driven bevel gear 14 can change the transmission direction, which is beneficial for the second motor 18 to drive the lifting screw 15 to rotate.
[0027] The outer surface of the lifting screw 15 is threaded with a slide 16. A mounting ring 6 is fixedly connected to one side of the outer surface of the slide 16, and the analysis cell 2 is fixedly installed inside the mounting ring 6. The two outer walls of the slide 16 slide against the two inner walls of the stroke groove 17 respectively. The stroke groove 17 has a limiting function on the slide 16, which can ensure the stability of the movement of the slide 16.
[0028] The bottom of the fixing frame 3 is evenly provided with multiple sample cup placement slots 12, and sample cup bodies 4 are placed inside the multiple sample cup placement slots 12. Multiple sealing rings 7 are evenly fixedly connected to the bottom of the fixing frame 3, and the sample cup placement slots 12 are located inside the sealing rings 7. The sealing rings 7 match the analysis cell 2, and the sealing rings 7 and the analysis cell 2 cooperate to have a sealing effect.
[0029] Working principle: Sample cups 4 filled with pure water are placed at intervals in the sample cup placement slot 12. Then, sample cups 4 filled with coating liquid, standard liquid, and detection liquid are placed in sequence. During detection, the first motor 8 operates intermittently, driving the transverse screw 10 to rotate. The transverse screw 10 drives the slider body 9 to move along the mounting slot 11. After reaching the corresponding position, the first motor 8 stops running, and the second motor 18 runs. The second motor 18 drives the active bevel gear 13 to rotate. The active bevel gear 13 drives the lifting screw 15 to rotate through the driven bevel gear 14. The lifting screw 15 drives the slide 16 to move downward along the stroke slot 17. The slide 16 drives the analytical cell 2 to descend through the mounting ring 6 until the bottom of the analytical cell 2 abuts against the sealing ring 7. At this time, the second motor 18 stops running, and the built-in electrode of the analytical cell 2 is inserted into the liquid inside the sample cup body 4. After the operation is completed, the second motor 18 drives the analytical cell 2 to rise through various components, and then the above operation is repeated.
[0030] It should be noted that, in actual use, the first motor 8 and the second motor 18 are electrically connected to the built-in controller of the analyzer 1 to facilitate overall control. The specific data analysis and processing involved to further realize the control function are methods that can be implemented by those skilled in the art based on common knowledge. These methods are not within the scope of this solution. The above description is only to illustrate the beneficial effects that can be achieved by this hardware structure improvement in conjunction with common knowledge.
