Description

Technical Field

[0001] The utility model relates to the technical field of sample storage equipment, in particular to an environmental monitoring sample storage equipment. Background Art

[0002] Environmental monitoring refers to the activities of environmental monitoring agencies to monitor and measure environmental quality. Environmental monitoring involves monitoring and measuring indicators that reflect environmental quality to determine the extent of environmental pollution and the level of environmental quality. Environmental monitoring primarily encompasses physical and chemical indicators, as well as ecosystem monitoring. It is the foundation for scientific environmental management and environmental law enforcement and supervision, and is essential foundational work for environmental protection.

[0003] When conducting water environment monitoring, the water in the environment needs to be placed inside a storage test tube, and the test tube is placed in a box for fixation. After subsequent water quality sample testing, the water environment conditions are comprehensively judged.

[0004] When testing certain components in water, samples often need to be sealed and protected from light to increase accuracy. However, while sealing multiple test tubes in existing sample storage boxes provides light protection, it significantly limits observation convenience. Opening the sample storage box directly for observation can affect the accuracy of test results due to the sudden introduction of light. To address this issue, we propose an environmental monitoring sample storage device that maintains a light-proof environment while allowing for convenient observation of the test tubes. Utility Model Content

[0005] In view of this, the purpose of the present invention is to provide an environmental monitoring sample storage device to solve the technical problem that after multiple groups of test tubes are sealed inside the existing sample storage box, it is inconvenient to perform comparative analysis on the test tubes inside the sample storage box.

[0006] The utility model is achieved through the following technical solutions:

[0007] An environmental monitoring sample storage device includes a sample storage box for storing test tubes and a fixing component for fixing the test tubes. The sample storage box is a hollow cylindrical structure with an open top. A cover body for closing the open top of the sample storage box is provided on the top of the sample storage box. A transparent window for observing the internal situation of the sample storage box is provided on the outer wall of the sample storage box. A closing ring is provided on the outer wall of the sample storage box, which can be rotated along the outer wall of the sample storage box and used to close the transparent window. An observation window is provided on the closing ring. By rotating the closing ring, the observation window and the transparent window can be overlapped or staggered.

[0008] Furthermore, the fixing component is a mounting plate horizontally arranged inside the sample storage box, and the mounting plate is provided with a plurality of fixing holes that pass through the mounting plate in the vertical direction and are used to clamp the test tubes, and the distances from the plurality of fixing holes to the transparent window are the same.

[0009] Furthermore, an elastic rubber clamping ring is provided in the fixing hole.

[0010] Furthermore, a stabilizing plate for stabilizing the bottom of the test tube is provided at the bottom of the sample storage box, and a plurality of downwardly concave grooves are provided at the bottom of the stabilizing plate, and the plurality of grooves correspond one-to-one to the bottoms of the plurality of test tubes.

[0011] Furthermore, the outer wall of the sample storage box is provided with a first connecting piece, and the outer wall of the closed ring is provided with a second connecting piece that can be detachably connected to the first connecting piece. When the first connecting piece is connected to the second connecting piece, the observation window and the transparent window are staggered.

[0012] Furthermore, the outer wall of the closed ring is provided with an anti-slip component.

[0013] Furthermore, the cover body includes a circular top plate and an annular connecting portion formed by extending downward from the outer edge of the circular top plate. The inner side wall of the annular connecting portion is provided with an internal thread, and the outer side wall of the top of the sample storage box is provided with an external thread.

These terms are intended solely to facilitate the description of the present invention and simplify the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" and the like are used solely for distinction and should not be construed as indicating or implying relative importance.

[0032] Furthermore, the term "identical" and similar terms do not necessarily require that the components be absolutely identical; slight variations are permitted.

[0033] See also Figure 1-7 The present invention provides a technical solution: an environmental monitoring sample storage device, comprising a sample storage box 1 for storing test tubes 20 and a fixing component for fixing the test tubes 20. The sample storage box 1 is a hollow cylindrical structure with an open top, through which the test tubes 20 can be stored and accessed, and the hollow structure provides a storage space for the test tubes 20. A cover 2 for closing the top opening of the sample storage box 1 is provided on the top of the sample storage box 1. After the cover 2 is closed, it can effectively prevent external gas and impurities from entering the sample storage box 1 and contaminating the water to be tested in the test tubes 20, thereby improving the accuracy of the detection. A transparent window 3 for observing the internal situation of the sample storage box 1 is provided on the outer wall of the sample storage box 1. Through the transparent window 3, the operator is allowed to directly observe the internal situation of the sample storage box 1 without opening the sample storage box 1. The situation inside the sample storage box 1, including the placement status of the test tube 20, the color change of the sample, etc., the outer wall of the sample storage box 1 is provided with a closing ring 4 that can be rotated along the outer wall of the sample storage box 1 and used to close the transparent window 3. The main function of the closing ring 4 is to close the transparent window 3 to reduce the possibility of external light passing through the transparent window 3 into the sample storage box 1 when observation is not required. An observation window 5 is provided on the closing ring 4. By rotating the closing ring 4, the observation window 5 can overlap or staggered with the transparent window 3. When the observation window 5 overlaps with the transparent window 3, the operator can clearly see the situation inside the sample storage box 1 through the observation window 5. When the two are staggered, the transparent window 3 is closed, which can better protect the sample environment inside the sample storage box 1.

[0034] When in use, the device is placed next to the water to be tested, and then the cover 2 is opened. The test tube 20 placed inside the sample storage box 1 is taken out, and the water to be tested is sucked up with a rubber-tipped dropper and transferred to the test tube 20. Then, the detection reagent is added and the top opening of the test tube 20 is sealed with a sealing plug. The test tube 20 is then transferred to the sample storage box 1 and fixed with a fixing component. The above operations are performed in sequence to obtain multiple test tubes 20 filled with water to be tested in the sample storage box 1 (in order to enrich the results of comparative analysis, the water to be tested will be taken from water to be tested at different positions and different depths. It should be noted that the water to be tested in one of the test tubes 20 should be a comparison sample as a benchmark). Then, the cover 2 is closed, and the closing ring 4 is rotated at intervals. The changes in the sample inside are observed through the observation window, and compared and analyzed with the comparison sample. After recording the analysis results, the test tube 20 is cleaned and the device is restored to its original state. By rotating the closing ring 4, when the observation window 5 overlaps with the transparent window 3, the operator can clearly see the situation inside the sample storage box 1 through the observation window 5, which is beneficial to the comparison and analysis of multiple test tubes 20. When the two are staggered, the transparent window 3 is closed, which can better protect the sample environment inside the sample storage box 1 and effectively reduce the impact of light on detection accuracy.

[0035] Specifically, the transparent window 3 is a curved glass plate embedded in the outer wall of the sample storage box 1 , and a first sealing ring is provided between the curved glass plate and the sample storage box 1 .

[0036] In this embodiment: In order to reduce the difference in distances from different test tubes 20 to the observation window 5 in the storage box and thereby improve the accuracy of comparative analysis of the test tubes 20, a fixing component is set as a mounting plate 6 located inside the sample storage box 1 and arranged horizontally. In this embodiment, the mounting plate 6 is a circular plate structure, and the outer wall of the mounting plate 6 is fixedly connected to the inner wall of the sample storage box 1. The mounting plate 6 provides a flat and stable support surface for the test tube 20. The mounting plate 6 is provided with a plurality of fixing holes 7 that pass through the mounting plate 6 in a vertical direction and are used to clamp the test tube 20. The fixing hole 7 is the key to clamping the test tube 20. The fixing hole 7 passes through the mounting plate 6 in a vertical direction, which means that the test tube 20 can be inserted into the hole from top to bottom and be firmly clamped. The distances from the multiple fixing holes 7 to the transparent window 3 are the same. By setting the distances from the multiple fixing holes 7 to the transparent window 3 to be the same, the distances from the multiple test tubes 20 to the transparent window 3 are the same, thereby reducing the influence of external light on the observation of the test tube 20 when the distances from the test tube 20 to the observation window 5 are different, thereby improving the accuracy of comparative analysis of the test tube 20.

[0037] In this embodiment: an elastic rubber snap ring 8 is provided in the fixing hole 7, and the elastic rubber snap ring 8 is bonded in the fixing hole 7. The elastic rubber snap ring 8 has a certain elasticity and friction. When the test tube 20 is inserted into the fixing hole 7, the rubber card can tightly wrap the wall of the test tube 20, thereby effectively reducing the possibility of the test tube 20 shaking or tilting in the sample storage box 1.

[0038] In this embodiment: a stabilizing plate 9 for stabilizing the bottom of the test tube 20 is provided at the bottom of the sample storage box 1. The stabilizing plate 9 is a circular plate structure, and its size is consistent with the size of the bottom of the sample storage box 1. The main function of the stabilizing plate 9 is to provide a stable support surface to bear and stabilize the bottom of the test tube 20. A plurality of downwardly concave grooves 10 are provided at the bottom of the stabilizing plate 9. The plurality of grooves 10 correspond one-to-one to the bottoms of the plurality of test tubes 20. The setting of the plurality of grooves 10 means that each test tube 20 has an exclusive support position, and not only increases the contact area between the test tube 20 and the stabilizing plate 9, and improves the stability of the test tube 20, but also can limit the movement range of the test tube 20 to a certain extent, and prevent the test tube 20 from unnecessary displacement in the sample storage box 1, thereby reducing the possibility of the test tube 20 tilting or shaking.

[0039] In this embodiment: a first connecting member 11 is provided on the outer wall of the sample storage box 1, and a second connecting member 12 that can be detachably connected to the first connecting member 11 is provided on the outer wall of the closed ring 4. When the first connecting member 11 is connected to the second connecting member 12, the observation window 5 and the transparent window 3 are staggered.

[0040] When the first connecting member 11 is connected to the second connecting member 12, the closed ring 4 is firmly fixed on the outer wall of the sample storage box 1. At this time, the observation window 5 and the transparent window 3 will be staggered, closing the transparent window 3 to prevent external light or pollutants from entering the interior of the sample storage box 1; when it is necessary to observe the internal situation of the sample storage box 1, the operator can easily disconnect the first connecting member 11 and the second connecting member 12, and then rotate the closed ring 4 to adjust the position of the observation window 5. When the observation window 5 overlaps with the transparent window 3, the operator can clearly see the internal situation of the sample storage box 1.

[0041] Among them, the first connecting member 11 and the second connecting member 12 can be matched with each other by means of buckles, snaps and bolts. In this embodiment, the first connecting member 11 is a pin slidably installed on the outer wall of the sample storage box 1, and the second connecting member 12 is a plug plate fixedly connected to the closed ring 4. The plug plate is provided with a plug hole for the plug to pass through. When the sliding plug is inserted into the plug hole, the first connecting member 11 and the second connecting member 12 are in a connected state. When the plug is pulled out of the pin hole, the first connecting member 11 and the second connecting member 12 are in a separated state.

[0042] Preferably, a sleeve 22 is provided on the outside of the latch, and the sleeve 22 is fixedly connected to the outer wall of the sample storage box 1. A return spring 21 is provided in the sleeve 22, and the return spring 21 is sleeved on the outside of the latch, and one end of the return spring 21 is fixedly connected to the latch, and the other end is fixedly connected to the sleeve 22. When the latch is inserted into the latch hole, the return spring 21 is in a free state. The free state here refers to the static state of the spring without being affected by external force. Pull the latch to disengage the latch from the latch hole. The return spring 21 is elastically stressed in this process. After slightly rotating the closed ring 4 to disengage the latch from the latch hole, release the latch (the latch automatically resets under the action of the return spring 21). Subsequently, rotate the closed ring 4 to observe the sample and lift the latch (the return spring 21 is elastically stressed in this process). Rotate the closed ring 4 again to realign the latch with the latch hole, release the latch, and insert the latch into the latch hole under the elastic force of the return spring 21.

[0043] In this embodiment, in order to facilitate the rotation of the closed ring 4 , an anti-slip component 13 is provided on the outer wall of the closed ring 4 . Specifically, the anti-slip component 13 is a plurality of anti-slip stripes spaced apart along the circumference of the closed ring 4 .

[0044] In this embodiment, the cover 2 includes a circular top plate 14 and an annular connecting portion 15 formed by extending downward from the outer edge of the circular top plate 14. The circular top plate 14, as the main part of the cover 2, provides a flat and wide surface, which is mainly used to close the top opening of the sample storage box 1. The annular connecting portion 15 is used to connect with the sample storage box 1 to achieve the connection between the cover 2 and the sample storage box 1. The inner wall of the annular connecting portion 15 is provided with an internal thread, and the outer wall of the top of the sample storage box 1 is provided with an external thread. The annular connecting portion 15 is connected to the top of the sample storage box 1 through threaded matching. When closing the cover 2, the operator aligns the annular connecting portion 15 with the external thread at the top of the sample storage box 1 and rotates the cover 2. As the rotation proceeds, the internal thread and the external thread gradually engage until they reach a tightly fitted state. At this time, the cover 2 is firmly fixed on the sample storage box 1, achieving the closure of the top opening of the sample storage box 1.

[0045] In this embodiment, to enhance the seal between the lid 2 and the sample storage box 1, a retaining ring 16 is provided on the outer wall of the top of the sample storage box 1. A second sealing ring 17 is embedded in the top of the retaining ring 16. The second sealing ring 17 is arranged circumferentially along the retaining ring 16. When the annular connecting portion 15 is connected to the top of the sample storage box 1, the bottom of the annular connecting portion 15 abuts against the top of the second sealing ring 17. The second sealing ring 17 is made of a soft and elastic sealing material, specifically rubber. When connecting the cover body 2 and the sample storage box 1, the operator first aligns the annular connection part 15 with the external thread on the top of the sample storage box 1 and starts to rotate the cover body 2. As the rotation proceeds, the annular connection part 15 gradually descends and approaches the limit ring 16. When the bottom of the annular connection part 15 contacts the top of the second sealing ring 17, due to the elastic effect of the second sealing ring 17, it will be slightly deformed to adapt to the shape of the annular connection part 15. As the rotation continues, the internal thread and the external thread gradually engage until a tight fit is reached. At this time, a firm sealing connection is also formed between the annular connection part 15 and the second sealing ring 17.

[0046] In this embodiment, a handle 18 is provided on the lid 2. This handle 18 allows the operator to move the entire sample storage box 1 by hand, eliminating the need for additional tools or the coordination of multiple personnel, thereby significantly improving the device's portability. Specifically, the handle 18 is a semicircular handle, with its ends hinged to opposite sides of the annular connecting portion 15. The handle 18 also serves as a storage unit. By rotating the handle 18 so that one side is parallel to the top of the lid 2, the handle 18 can be stored.

[0047] In this embodiment, a storage section 19 for storing a coolant is provided within the sample storage box 1. The coolant is a substance that can maintain a low temperature after absorbing heat, and specifically, can be an ice pack. In environmental monitoring, many samples need to be analyzed and tested under low-temperature conditions. The above arrangement provides a low-temperature testing environment within the sample storage box 1. Specifically, the storage section 19 is a circular tubular structure vertically disposed within the sample storage box 1 with an open top. The coolant is placed into the storage section 19 through the open top.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
