Description

Technical Field

[0001] This utility model relates to the field of marine environmental monitoring technology, specifically to a sample storage device for marine environmental monitoring. Background Technology

[0002] Marine environmental monitoring is a crucial step in studying marine ecology, assessing environmental pollution, and protecting marine resources. The monitoring process involves collecting seawater, sediment, or biological samples from different depths and locations, and safely transporting them to the laboratory for analysis. These samples are typically contained in containers of various sizes, such as test tubes, flasks, or column sampling tubes.

[0003] Currently, common sample storage devices are mostly simple fixed supports or foam-padded compartments. On operating platforms such as marine survey vessels, these devices are subject to severe shaking due to the ship's rocking and turbulence, causing the internal sample containers to collide, tip over, or even break, resulting in the loss or contamination of valuable samples. Furthermore, existing devices are difficult to adapt to sample containers of different heights and diameters simultaneously, exhibiting poor versatility. For long cylindrical samples, the bottom is not securely fixed, and the top lacks restraint, making them highly susceptible to breakage due to inertia during transportation. Therefore, a sample storage device for marine environmental monitoring is proposed. Utility Model Content

Existing devices are difficult to adapt to containers of different heights and diameters, exhibiting poor versatility. For long cylindrical samples, there are even more problems such as unstable bottom fixation and lack of top restraint, making them extremely prone to breakage during transportation.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sample storage device for marine environmental monitoring, comprising a fixed box and a storage mechanism. The surface of the fixed box is provided with a storage groove, and the top of the fixed box is provided with a handle. The storage mechanism is movably installed in the storage groove. The storage mechanism includes a storage box and a base plate. The two side walls of the storage box are respectively connected to the fixed box by guide rails. An adjustment plate is vertically and fixedly connected to one side of the bottom of the storage box. The surface of the adjustment plate is evenly provided with several adjustment holes, and an adjustment bolt is installed in one of the adjustment holes. The adjustment bolt is threadedly connected to the base plate. The surface of the storage box is provided with a partition and is divided into several storage holes by the partition. A clamping mechanism is installed inside the storage box.

[0008] As a further preferred embodiment of the present invention, the clamping mechanism includes a screw and a clamping plate.

[0013] (III) Beneficial Effects

[0014] This invention provides a sample storage device for marine environmental monitoring. It has the following beneficial effects:

[0015] Comprehensive sample fixation and shock absorption: An adjustable clamping mechanism and bottom positioning groove effectively secure the sample container to the middle and bottom. The air bladder in the clamping mechanism features anti-slip protrusions, adapting to containers of different diameters, providing flexible clamping force, and effectively cushioning vibrations to prevent shaking, collisions, and surface scratches during transportation.

[0016] Flexible adaptation to different sample sizes: Height adjustment: By adjusting the bolts and different height adjustment holes, the relative distance between the base plate and the storage box can be changed, thus flexibly adapting to sample containers of different heights and ensuring stable bottom support for both short test tubes and long cylindrical sample tubes. Diameter adjustment: By rotating the turntable to drive the screw, the two sets of clamping plates can move synchronously in opposite directions, easily adjusting the clamping distance to accommodate sample containers of different diameters, making it highly versatile.

[0017] Top limiting to prevent movement: The handle bolt and pressure plate structure on the top of the fixing box can apply flexible pressure to the top of the sample container placed in the storage hole. It works in conjunction with the positioning and support at the bottom to effectively prevent the sample from moving up and down in the vertical direction. It is especially suitable for fragile columnar samples and avoids sample breakage caused by bumps. The protective sealing gasket at the bottom of the pressure plate can limit and seal the sample tube from the top.

[0018] The device boasts a stable structure and convenient loading and unloading: the storage box is movably connected to the fixed box via guide rails, ensuring both smooth sliding and overall structural stability. The handle design facilitates carrying and transporting the entire device. With its rational overall structural design and simple operation, the device significantly improves the safety and reliability of marine environmental monitoring sample storage.

[0023] 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.

[0024] Please see Figure 1-3This utility model provides a technical solution: a sample storage device for marine environmental monitoring, including a fixed box 1 and a storage mechanism 3. The fixed box 1 has a storage groove 2 on its surface and a handle 6 on its top. The storage mechanism 3 is movably installed within the storage groove 2. The storage mechanism 3 includes a storage box 8 and a base plate 14. Guide rails 4 are movably connected to the fixed box 1 on both side walls of the storage box 8. An adjusting plate 15 is vertically and fixedly connected to one side of the bottom of the storage box 8. Several adjusting holes 16 are evenly distributed on the surface of the adjusting plate 15. An adjusting bolt 17 is installed in one of the adjusting holes 16 and is threadedly connected to the base plate 14. A partition 9 is installed on the surface of the storage box 8, dividing it into several storage holes 10. A clamping mechanism is installed inside the storage box 8. Through the cooperation of the adjusting plate 15 and the adjusting bolt 17, the distance between the base plate 14 and the storage box 8 can be flexibly adjusted to accommodate sample containers of different heights (such as short test tubes and long cylindrical sample tubes). The storage box 8 is connected to the fixed box 1 via the guide rail 4, which ensures both the convenience of pulling out and putting in samples and the structural stability of the entire storage mechanism 3 in the closed state, effectively preventing the whole device from coming off in a bumpy environment. The design of the "handle 6" greatly facilitates the carrying and handling of the entire device.

[0025] Further improvements include a clamping mechanism comprising a screw 19 and clamping plates 20. The screw 19 is rotatably mounted in the middle of the storage box 8, with one end extending outside the storage box 8 and connected to a turntable 18. The surface of the screw 19 is symmetrically provided with several sets of threaded structures, each connected to a threaded sleeve 21. The clamping plates 20 are positioned below the partition 9, symmetrically arranged and connected to the threaded sleeves 21. Rotating one turntable 18 drives the screw 19 to rotate. Due to the symmetrical threads on the screw 19, the two threaded sleeves 21 that engage with it drive the two sets of clamping plates 20 to move synchronously towards or away from each other. This single-point control, multi-point linkage mechanism allows the user to simultaneously fix or release all samples in the storage holes 10 with a single operation, resulting in high operational efficiency, ensuring consistent clamping force, and avoiding the tedious process of adjusting each sample individually.

[0026] Further improvements include clamping grooves 22 on the opposite surfaces of the two symmetrically arranged clamping plates 20, positioned below the storage hole 10. An airbag pad 23 is installed inside the clamping groove 22, and its surface is provided with anti-slip protrusions. The clamping groove 22 provides a clearly defined positioning space for clamping. The airbag pad 23 inside is a key innovation; it can adapt to the slight irregularities of containers of different diameters, providing uniform elastic clamping force and avoiding container cracking or scratching that may occur with rigid clamping. The anti-slip protrusions further increase friction, preventing the container from rotating or slipping at the clamping point. Combined with the cushioning properties of the airbag, this provides excellent shock absorption protection for the sample during transportation.

[0027] Further improvements include through holes 11 at the corners of the surface of the storage box 8, and a connecting rod 12 vertically installed at the corner of the top surface of the base plate 14. The upper end of the connecting rod 12 extends into the through hole 11 and is movably connected to it. When the height of the base plate 14 is changed by adjusting the bolt 17, the connecting rod 12 slides up and down within the through hole 11. This structure plays a crucial guiding and supporting role, effectively preventing the base plate 14 from tilting, jamming, or rotating during lifting, ensuring a smooth and stable adjustment process. Simultaneously, it also shares some of the load on the adjusting bolt 17 with the sample weight, enhancing the strength and durability of the entire adjustment mechanism.

[0028] Further improvements include several positioning grooves 13 on the top surface of the base plate 14, positioned below the storage hole 10. These positioning grooves 13 are concentrically aligned with the storage hole 10 above, effectively securing the bottom of the sample container in a fixed position and preventing it from sliding on the horizontal plane. Combined with the clamping mechanism, this forms a dual fixing system of bottom positioning and central clamping, greatly enhancing the container's stability in three-dimensional space and effectively preventing tipping and shaking.

[0029] Further improvements include a pressure plate 5 located inside the fixing box 1 and above the storage box 8. A handle bolt 7 is threadedly connected to the center of the top surface of the fixing box 1, with its end rotatably connected to the center of the top surface of the pressure plate 5. A protective sealing gasket is located at the bottom of the pressure plate 5 and above the storage hole 10. For columnar samples with a large length-to-diameter ratio, fixing only the bottom and middle is insufficient, as the top may swing significantly during bumps, potentially causing sample breakage. By tightening the handle bolt 7, the pressure plate 5 can be driven downwards, applying a controllable and flexible pressure to the top of the sample. This structure, combined with the bottom support and positioning, achieves three-point fixation (top, middle, and bottom) for long samples, completely limiting their vertical movement and large swings, which is a key guarantee against breakage of long samples (such as sediment columnar samples) during transportation. Simultaneously, the protective sealing gasket also seals the top opening of the container and provides a certain degree of cushioning.

[0030] Working Principle: First, select the appropriate adjustment hole 16 according to the height of the sample container to be stored, and use the adjustment bolt 17 to adjust the base plate 14 to the appropriate height so that the height is moderate after the container is placed. Then, place the sample containers one by one into the storage holes 10 formed by the partition 9, and make the bottom of the container sit in the positioning groove 13 on the base plate 14. Rotate the turntable 18 clockwise to drive the screw 19 to rotate. The symmetrical threads on the screw 19 drive the two screw sleeves 21 and the clamping plates 20 connected to them to move synchronously in opposite directions. The air cushions 23 on the clamping plates 20 will flexibly hold the middle of each sample container, and firmly fix it through friction and elastic deformation to prevent horizontal movement and collision. For long samples that require special protection, after the middle clamping is completed, tighten the handle bolt 7 on the top of the fixing box 1 to drive the pressure plate 5 to move downward until the pressure plate 5 gently contacts the top cover or top surface of the sample container, thereby preventing the sample from moving up and down during transportation. The operating handle 6 can lift and move the entire device. When samples need to be retrieved, loosen the handle bolt 7 to release the top pressure, pull the storage box 8 out of the fixed box 1, and rotate the turntable 18 in the opposite direction to release the clamp 20, allowing the sample to be safely removed. The entire storage mechanism 3 can be pulled out of the fixed box 1 via the guide rail 4 for easy cleaning and maintenance.

[0031] The components of this utility model are: 1. Fixing box; 2. Storage slot; 3. Storage mechanism; 4. Guide rail; 5. Pressure plate; 6. Handle; 7. Handle bolt; 8. Storage box; 9. Partition; 10. Storage hole; 11. Through hole; 12. Connecting rod; 13. Positioning slot; 14. Base plate; 15. Adjusting plate; 16. Adjusting hole; 17. Adjusting bolt; 18. Turntable; 19. Screw; 20. Clamping plate; 21. Screw sleeve; 22. Clamping groove; 23. Airbag cushion. All components are general standard parts or parts known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. The problem solved by this utility model is that during offshore operations, the rocking of the ship can easily cause the sample containers inside the device to collide, tip over, or even break, resulting in sample loss. Existing devices are difficult to adapt to containers of different heights and diameters, resulting in poor versatility. For long cylindrical samples, there are problems such as unstable bottom fixation and lack of top restraint, making them prone to breakage during transportation. This utility model addresses these issues by combining the aforementioned components. Through an adjustable clamping mechanism and a bottom positioning groove 13, it effectively fixes the middle and bottom of the sample container. The airbag 23 in the clamping mechanism has anti-slip protrusions, which can adapt to containers of different diameters, providing flexible clamping force while effectively buffering vibrations and preventing the container from shaking, colliding, and scratching its surface during transportation. By adjusting the bolt 17 in conjunction with the adjustment holes 16 of different heights, the relative distance between the base plate 14 and the storage box 8 can be changed, thus flexibly adapting to sample containers of different heights and ensuring stable bottom support for both short test tubes and long cylindrical sample tubes. Diameter adjustment: By rotating the turntable 18 to drive the screw 19, the two sets of clamping plates 20 can move synchronously towards or away from each other, easily adjusting the clamping distance to adapt to sample containers of different diameters, demonstrating strong versatility. The handle bolt 7 and pressure plate 5 structure at the top of the fixing box 1 can apply flexible pressure to the top of the sample container placed in the storage hole 10, which cooperates with the positioning and support at the bottom to effectively prevent the sample from moving up and down in the vertical direction. It is especially suitable for fragile columnar samples, avoiding sample breakage caused by bumps. The protective sealing gasket at the bottom of the pressure plate 5 can limit and seal the sample tube from the top. The storage box 8 is movably connected to the fixing box 1 through the guide rail 4, which ensures both smooth pushing and pulling and the stability of the overall structure. The handle 6 is designed to facilitate carrying and handling of the entire device. The overall structure of the device is reasonably designed and easy to operate, which greatly improves the safety and reliability of marine environmental monitoring sample storage. The above shows and describes the basic principles and main features of this utility model and its advantages. For those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
