Description

Technical Field

[0001] This utility model relates to the field of water quality sample classification technology, and in particular to a sample classification device for water quality component detection. Background Technology

[0002] With the continuous development of water quality monitoring technology, the detection of water components has become an important means of ensuring the ecological safety of aquatic bodies and public health. In the process of water quality testing, the storage and classification management of samples are crucial. How to effectively classify and store water samples from different sources and with different compositions, prevent cross-contamination, and ensure the stability of samples during handling and storage is a key issue that urgently needs to be addressed in water quality testing equipment. Therefore, developing a sample classification device that can classify, stably store, and facilitate subsequent processing of water samples is particularly important.

[0003] Currently, water samples are typically stored and classified using simple containers or boxes. In existing technologies, most devices separate samples using boxes or partitions to achieve classified storage. Chinese Patent CN213355498U discloses a sample storage device for storing sample containers, comprising: a box; a first partition fixedly disposed within the box cavity, having several first through holes penetrating the thickness direction of the first partition, the diameter of which is configured to allow sample containers to pass through; a first elastic element disposed at the bottom of the box; a second partition disposed on the first elastic element; and a first buffer pad disposed on the second partition, located on the side facing the first partition. This device offers the advantage of classified storage, fixing sample containers through a multi-level elastic buffer structure, solving the problem of sample containers being easily disturbed by humans, thus creating better sample conditions for subsequent exploration and testing, and improving testing accuracy. However, these partitions are fixed and cannot be flexibly adjusted according to actual needs. To facilitate sample storage and retrieval, the device is equipped with clamps or supports within the housing to ensure that samples do not tilt or scatter during storage. The device also utilizes springs or elastic structures to provide auxiliary force, helping the clamps or containers to better secure the samples. However, this device often suffers from problems such as samples easily tipping over during handling, insufficient sample fixation, or inaccurate classification, affecting its stability and practicality during use.

[0004] Existing water sample storage devices are prone to inaccurate sample classification or unstable storage in practical applications. Particularly during sample handling or storage, failure to effectively secure water samples can lead to tilting or scattering, affecting sample classification and subsequent analysis. This not only increases the difficulty of manual intervention but also causes inconvenience in sample processing, impacting the efficiency and accuracy of testing. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a sample classification device for water quality component detection, which aims to improve the problem that the sample classification device is prone to tipping over when the water quality sample is placed directly inside the box.

Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 This utility model provides an embodiment of a sample classification device for water quality component detection, comprising a housing 1, with a lid 2 rotatably connected to the top of the housing 1. The housing 1 is used to store water quality samples. The lid 2 facilitates sealing of the housing 1, preventing external environmental contamination of the samples and improving the airtightness and safety of storage. An inner liner 3 is fixedly connected inside the housing 1. A partition 4 is provided inside the inner liner 3 to divide the storage space, allowing samples to be classified and stored according to different categories, avoiding sample mixing. A bracket 5 is fixedly connected to one side of the partition 4, supporting the installation of the fixing components for stable operation. A fixing component is provided on one side of the bracket 5.

[0038] The fixing assembly includes a housing 6, one end of which is fixedly connected to one side of the bracket 5. The housing 6 is used to house the internal reset assembly and connecting mechanism, making the entire fixing mechanism more stable. A connecting post 7 is slidably connected inside the housing 6, and a connecting plate 8 is fixedly connected to one end of the connecting post 7. The connecting plate 8 is used to drive the clamping plate 14 to clamp and fix the sample bottle, ensuring that the sample is not easily tipped over during storage and transportation. A limiting groove 10 is provided inside the connecting plate 8. The limiting groove 10 is used to provide the sliding trajectory of the connecting rod 11 to ensure that the clamping plate 14 maintains stable force during the fixing process. A rotating shaft 9 is rotatably connected to one side of the bracket 5. The outer wall of the rotating shaft 9 is rotatably connected to the connecting rod 11. One end of the connecting rod 11 is slidably connected inside the limiting groove 10, so that the connecting rod 11 can move stably along the limiting groove 10. The other end of the connecting rod 11 is rotatably connected to the clamping plate 14. The clamping plate 14 is used to clamp the sample bottle and fix it in a proper position to avoid shaking and affect the storage stability. A reset assembly is provided inside the housing 6. The reset assembly includes a first spring 12. The first spring 12 is located inside the housing 6 and is used to provide elastic restoring force so that the connecting plate 8 and the clamping plate 14 can automatically reset after being released, ensuring that the clamping plate 14 can quickly return to the initial state, which is convenient for placing new sample bottles. One end of the first spring 12 is fixedly connected to the inside of the housing 6, and the other end is fixedly connected to the other end of the connecting column 7, ensuring rapid reset when the connecting plate 8 is moved under force, thus improving the ease of operation and stability of the device. An adaptation component is provided inside the clamping plate 14, including a ball 15. The ball 15 is slidably connected inside the clamping plate 14, allowing the clamping plate 14 to adaptively adjust according to the shape of the sample bottle, improving the clamping effect and ensuring stable fixation of sample bottles of different diameters. A second spring 16 is provided inside the clamping plate 14, with one end fixedly connected to the outer wall of the ball 15. The second spring 16 provides auxiliary elasticity, allowing the ball 15 to make fine adjustments under force to adapt to sample bottles of different shapes and sizes, improving the adaptability of the device. The other end of the second spring 16 is fixedly connected inside the clamping plate 14, ensuring the ball 15 is always in a stable force state, guaranteeing the reliability of sample fixation.

[0039] Reference Figure 1 and Figure 3The inner liner 3 has a second limiting groove 22 inside, which provides a sliding path for the partition 4, ensuring that the partition 4 can be adjusted along a set path to adapt to the storage needs of samples of different sizes and quantities, thus improving the flexibility of the device. The partition 4 is slidably connected inside the second limiting groove 22, so that it remains stably stressed during adjustment, avoiding tilting or shaking, ensuring reasonable division of storage space, and improving the neatness of sample storage. The inner liner 3 also has a slot 17 inside, which provides an additional positioning area for the partition 4, allowing it to be stably inserted and maintained in a fixed state, preventing the partition 4 from shifting when subjected to external forces, and improving the stability of the device. The partition 4 has a slot 13 inside, which is used to engage with the wedge-shaped locking block 21 to lock the partition 4 in place. This prevents the partition 4 from loosening due to vibration or movement, thus ensuring proper sample classification and storage. A support plate 18 is fixedly connected inside the inner liner 3. The support plate 18 provides support for the wedge-shaped locking block 21, ensuring its stability when engaged with the slot 13 and preventing loosening that could affect the fixation. The support plate 18 has a stress groove 19 inside, which allows it to deform appropriately under external force. This facilitates the assembly and disassembly of the wedge-shaped locking block 21, reducing damage to the partition 4 and support plate 18 during assembly and disassembly, improving service life and assembly efficiency. A wedge-shaped locking block 21 is fixedly connected to one side of the support plate 18, engaging with the slot 13 to firmly fix the partition 4 in the designated position, preventing it from shifting due to external force and improving the overall stability of the device. The support plate 18 has a groove 20 on its top. The groove 20 facilitates the separation of the wedge-shaped locking block 21 on one side of the support plate 18 from the slot 13, making it easier to disassemble and reinstall the partition 4 when adjustment is needed, thus improving the flexibility and operability of the device. The stress groove 19 allows the support plate 18 to deform and bend slightly under external force, making it easier for the wedge-shaped locking block 21 to separate from the slot 13, thereby reducing operating resistance and improving disassembly and assembly efficiency. The support plate 18 is L-shaped. The L-shaped structure provides better stress support, making it easier to disassemble and assemble the wedge-shaped locking block 21 on one side of the support plate 18 from the slot 13, while enhancing the stability of the overall structure and preventing deformation or loosening due to long-term use, further improving the durability and applicability of the device.

[0040] Working principle: When using this water quality component detection sample classification device, the water quality test samples need to be classified and placed first. The partition 4 is distinguished by multiple limiting grooves 22 set in the inner tank 3. The partition 4 is inserted into the limiting grooves 22 to divide the sample. At the same time, the partition 4 is locked by the wedge-shaped locking block 21 in the inner tank 3 and the locking groove 13. The wedge-shaped locking block 21 is connected to the inner tank 3 through the support plate 18. The support plate 18 is L-shaped and the stress groove 19 opened inside can make the support plate 18 slightly deform, which facilitates the engagement and separation of the wedge-shaped locking block 21 and the locking groove 13, thus achieving the effect of conveniently storing samples in different sections.

[0041] When placing a water sample, first press the connecting plate 8 towards the partition 4, so that the connecting plate 8 guides the connecting rod 11 to rotate around the pivot 9 through the internal limiting groove 10, thereby opening the clamp 14. Then, the water sample is placed between the clamps 14. After releasing the connecting plate 8, the tension of the first spring 12 supports the connecting plate 8 to reset through the connecting column 7, thereby driving the clamp 14 to reset and fit against the outer wall of the sample. The clamp 14 and the sample are held together by the ball 15, and the ball 15 and the clamp 14 are supported by the tension of the second spring 16, so that the ball 15 can adapt to the outer wall of samples of different sizes, achieving the effect of facilitating the fixation of the sample and better fitting the bottle body.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
