[0002] In water conservancy projects, to strengthen water environment quality monitoring, promptly grasp the current water quality status, determine the spatial and temporal distribution of pollutants in water bodies, and further trace the sources, pathways, and impacts on human health of pollutants, extensive on-site water sampling is required. To understand the water environment quality, the sampled water samples need to undergo various characteristic index tests in the laboratory. Therefore, after water sampling, the samples must be stored using sample storage devices.

[0003] After sampling, water samples are usually stored in columnar sample tubes. To protect the sample tubes, they are usually installed in a sample storage box by plugging them in. Traditional storage boxes are usually installed and connected by simple plugging. However, since the inserted test tubes lack restraint, they are prone to falling off when the box is tilted or turned over. Furthermore, the test tubes will experience significant axial shaking inside the box when it is moved, resulting in poor storage safety. Therefore, a water quality sample storage device for water conservancy projects is proposed. Utility Model Content

[0026] Please see Figure 1-6 This utility model provides a technical solution: a water quality sample storage device for water conservancy projects, including a box mechanism and a test tube mechanism. The box mechanism includes a storage box 1, a protective cover 2, an inner mounting seat 3, a mounting limit plate 4, a first spring 5, an unlocking knob 6, a drive shaft 7, and a drive cable 8. The inner mounting seat 3 is enclosed inside the storage box 1 by the protective cover 2, as shown in the attached figure. Figure 2 As shown, to facilitate the connection and installation of the protective cover 2, a connecting hinge is provided at the rear of the storage box 1. The protective cover 2 is hinged to the upper part of the storage box 1 via the connecting hinge. To limit the closure of the protective cover 2 after it is closed, as shown in the attached diagram... Figure 1 As shown, a safety lock 12 is provided on the flip-closed side of the protective cover 2 and the storage box 1. In order to facilitate the lifting and moving of the storage box 1, a hidden groove is provided in the middle of the top side of the protective cover 2. A handle 13 is installed inside the hidden groove by flipping and fitting. The handle 13 adopts a flip-hidden structure, which can facilitate the stacking of the boxes.

[0027] The test tube mechanism is installed inside the housing mechanism. The test tube mechanism includes a sample storage tube 9 and a sealing end cap 10, as shown in the attached diagram. Figure 4 As shown, the sealing end cap 10 is threadedly installed on the upper part of the sample storage tube 9, forming a sealed sample storage structure. The mounting inner seat 3 is used for the storage, installation, and protection of the sample storage tube 9, as shown in the attached diagram. Figure 3As shown, the mounting base 3 is fixedly installed inside the storage box 1. In order to store and install the sample storage tube 9, a sample tube installation hole is provided in the middle of the mounting base 3. The sample tube installation holes are evenly opened in a matrix in the middle of the mounting base 3, which can store and install multiple sets of sample storage tubes 9. After installation, the sample storage tube 9 is fitted and inserted into the sample tube installation hole.

[0028] The mounting limit plate 4 is movably mounted on the lower inner side of the mounting inner seat 3 by being pushed against by the first spring 5, as detailed in the attached document. Figure 5 As shown, a plate mounting groove is laterally provided at the lower part of the mounting inner seat 3. The mounting limiting plate 4 is slidably fitted into the inner side of the plate mounting groove. The first spring 5 is installed against the end side of the mounting limiting plate 4, providing elastic pushing force for the mounting limiting plate 4. In order to cooperate with the sample storage tube 9, rectangular slots are evenly and equidistantly opened in the middle of the mounting limiting plate 4. In order to cooperate with the mounting limiting plate 4, a limiting ring groove 11 is provided at the lower part of the sample storage tube 9. The limiting ring groove 11 is fitted and snapped into the side plate of the rectangular slot. A plate snap-fit ​​limiting anti-detachment protective structure is adopted for storage. The interior of the housing 1 is equipped with an installation limiting plate 4, which is movably installed by a first spring 5. The installation limiting plate 4 engages with the lower limiting annular groove 11 of the sample storage tube 9 to limit and protect the sample storage tube 9 after installation. This prevents the sample storage tube 9 from detaching from the housing 1 and from falling out, while also preventing excessive axial displacement of the sample storage tube 9 through the locking mechanism, greatly improving the storage safety of the device. To facilitate the insertion and installation of the sample storage tube 9, a spherical end is provided at the bottom of the sample storage tube 9. For auxiliary limiting of the installed sample storage tube 9, see attached... Figure 3 As shown, protective protrusions 14 are evenly arranged on the inner side of the protective box cover 2. The protective protrusions 14 are soft protrusions that can support and limit the end of the sample storage tube 9 after installation through abutment support.

[0029] Driven by the unlocking knob 6, the drive shaft 7 is pulled and installed to the end of the mounting limit plate 4 via the drive cable 8. See attached diagram for details. Figure 5 As shown, the drive shaft 7 is rotatably mounted inside the shaft hole provided on the side of the mounting inner seat 3. The unlocking knob 6 is fixedly mounted on the upper end of the drive shaft 7. A traction wheel is fixedly mounted on the lower part of the drive shaft 7. One end of the drive pull cable 8 is fixedly mounted to the traction wheel, and the other end of the drive pull cable 8 is fixedly connected to the middle of the end side of the mounting limit plate 4. The end of the mounting limit plate 4 is connected to the drive shaft 7 through the drive pull cable 8. During operation, the mounting limit plate 4 can be driven to move laterally by turning the unlocking knob 6 and using the winding pull of the wheel in the middle of the drive shaft 7, thereby realizing the unlocking and retrieval of the sample storage tube 9. The structure is simple and the operation is convenient, which helps to improve the convenience of retrieving the sample storage tube 9.

[0030] To temporarily lock and limit the position of the unlocking knob 6 after it has been turned, as shown in the attached document. Figure 6 As shown, a ball-head protrusion 15, a second spring 16, and a threaded protrusion 17 are arranged in pairs on the upper part of the unlocking knob 6. The ball-head protrusion 15 is slidably inserted into the inner side of the sliding hole provided on the upper part of the unlocking knob 6. The second spring 16 is pressed down and abutted against the upper part of the ball-head protrusion 15 by the threaded protrusion 17. The end of the ball-head protrusion 15 moves through the lower part of the unlocking knob 6 and is engaged with the limiting groove provided on the upper part of the mounting inner seat 3. The engagement of the limiting groove with the end of the ball-head protrusion 15 can achieve temporary limiting of the unlocking knob 6 after it is turned.

[0031] Working principle or structural principle: During use, with the unlocking knob 6 in the default locked state, the sample storage tube 9 after sampling is inserted into the inner side of the mounting hole on the upper part of the mounting base 3. During insertion, the spherical end of the sample storage tube 9 guides the mounting limiting plate 4 to slide to the right. Then, the first spring 5 pushes the side plate of the mounting limiting plate 4 to engage with the limiting ring groove 11, completing the limiting installation of the sample storage tube 9. After the sample storage tubes 9 are installed, the protective box cover 2 is closed by flipping it over, and the safety lock 12 is engaged and locked. After closing, the protective protrusion 14 on the inner side of the protective box cover 2 contacts and supports the upper end of the sample storage tube 9, cooperating with the mounting limiting plate 4. The locking mechanism prevents excessive axial displacement of the sample storage tube 9, thus protecting its installation. When retrieving the sample, after opening the protective cover 2, turn the unlocking knob 6. This drives the drive shaft 7 to pull the installation limiting plate 4 laterally via the drive cable 8, causing the side plate of the installation limiting plate 4 to disengage from the limiting ring groove 11, thereby unlocking the sample storage tube 9. Simultaneously, when the unlocking knob 6 is turned to the unlocked position, the ends of the two sets of ball-head protrusions 15 at the bottom of the unlocking knob 6 engage with the limiting groove on the bottom side of the rotating groove, thus limiting the rotation of the unlocking knob 6 and keeping it in the unlocked state. Afterward, the sample storage tube 9 can be retrieved and used from the storage box 1.

[0032] In summary, this storage device adopts a plate-type snap-fit ​​limiting anti-detachment protection structure. An installation limiting plate 4 is installed inside the storage box 1. The installation limiting plate 4 is moved and installed by a first spring 5. It engages with the lower limiting annular groove 11 of the sample storage tube 9 to limit and protect the sample storage tube 9 after installation. This prevents the sample storage tube 9 from detaching and falling out of the storage box 1, while also preventing excessive axial displacement of the sample storage tube 9 through snap-fit ​​limiting, greatly improving the storage safety of the device. The end of the installation limiting plate 4 is connected to the drive shaft column 7 via a drive cable 8. During operation, the installation limiting plate 4 can be moved laterally by turning the unlocking knob 6, utilizing the winding pull of the wheel in the middle of the drive shaft column 7, thus unlocking and retrieving the sample storage tube 9. The structure is simple and easy to operate, improving the convenience of retrieving the sample storage tube 9.
