Description

Technical Field

[0001] This utility model relates to the field of sample storage technology, and in particular to a sample storage device for environmental geological exploration. Background Technology

[0002] Environmental geological survey samples include water (surface water, groundwater, wastewater), soil and sediments, rocks and minerals (specimens, cores), biological samples, and atmospheric deposition. These samples are mainly used to detect pollutants and assess geological structures and ecological risks. To avoid vibration pollution and the influence of external temperature, water samples in environmental geological surveys are usually stored in refrigerated boxes equipped with rubber positioning sleeves using sampling bottles.

[0003] Although the rubber positioning sleeve can adaptively lock sampling bottles of different sizes, as the diameter of the sampling bottle increases, the tightness of the connection between it and the rubber positioning sleeve will also increase accordingly. This tight contact will hinder the circulation of cold air inside the refrigerator, resulting in uneven temperature distribution inside the refrigerator. Utility Model Content

[0004] Therefore, it is necessary to provide an environmental geological exploration sample storage device to address the problem of poor refrigeration storage effect in existing environmental geological exploration sample storage devices.

[0005] An environmental geological exploration sample storage device, comprising:

[0006] A refrigerator, wherein an ice pack placement cavity is provided in the inner bottom wall of the refrigerator;

[0007] The positioning and storage mechanism includes a mounting frame fixedly connected to the inside of the refrigerator. The mounting frame has aligned placement holes at both its top and bottom ends. An adjusting screw is rotatably connected to the top of the mounting frame. The rod of the adjusting screw extends through the inner side of the mounting frame. The rod of the adjusting screw is threadedly connected to a mounting frame aligned with the placement hole. Positioning springs arranged in a ring around the centerline of the placement hole are fixedly connected between the mounting frame and the placement hole above.

[0008] In one embodiment, the horizontal cross-sectional shape of the upper placement hole is circular, and the horizontal cross-sectional shape of the lower placement hole is rectangular, with the lower placement hole being larger than the horizontal cross-sectional dimension of the upper placement hole.

[0009] In one embodiment, a support mesh, which is a nylon material component, is embedded inside the placement hole described below.

[0010] In one embodiment, the vertical cross-sectional shape of the positioning spring is V-shaped, and the V-shaped opening of the positioning spring faces away from the axis of the placement hole.

[0011] In one embodiment, a flexible sealing sleeve is fixedly connected between the mounting frame and the placement hole above, and the positioning spring is distributed in a ring shape on the outside of the flexible sealing sleeve.

[0012] In one embodiment, the flexible sealing sleeve is hourglass-shaped and is a silicone material component.

[0013] In one embodiment, a guide rod is inserted into the bottom of the mounting frame, and the top of the guide rod passes through the mounting frame and is fixedly connected to the mounting bracket.

[0014] In one embodiment, the inner bottom wall of the refrigerator is provided with threaded grooves that are staggered with the ice pack placement cavity, and the top of the mounting bracket is rotatably connected to a connecting screw, the bottom of which passes through the mounting bracket and is threadedly connected to the threaded groove. Beneficial effects

[0015] The aforementioned environmental geological exploration sample storage device achieves adaptive sealing for sampling bottles of different diameters through the synergistic action of a flexible sealing sleeve and positioning springs. The hourglass-shaped silicone structure of the flexible sealing sleeve, driven by an adjusting screw, changes its inner diameter by moving the mounting frame up and down, completely sealing the gap between the sampling bottle and the upper placement hole. This design effectively prevents external heat from entering the mounting frame. Simultaneously, the nylon material of the support mesh avoids localized overcooling caused by direct heat conduction, ensuring that the sample remains in a uniform and stable low-temperature environment throughout the transport process.

[0016] The positioning and storage mechanism employs a three-tiered protection system: an elastically wrapped flexible sealing sleeve, V-shaped elastic support from the positioning springs, and flexible support from the support mesh. When the device is subjected to vibration, the flexible silicone sealing sleeve absorbs over 90% of the impact energy through deformation, with the remaining energy being buffered secondary by the metallic memory properties of the positioning springs. The support mesh disperses the pressure at the bottom of the bottle through its mesh structure, and its rectangular bottom placement hole design increases the stress-bearing area, ensuring stable use of the sampling bottle even under bumpy conditions.

[0029] The following is combined Figures 1-4 This invention describes an environmental geological exploration sample storage device.

[0030] In one embodiment, an environmental geological exploration sample storage device includes: a refrigerator 100 and a positioning storage mechanism 200, wherein the inner bottom wall of the refrigerator 100 has an ice pack placement cavity 110.

[0031] like Figure 2 , Figure 3 and Figure 4 As shown, the positioning and storage mechanism 200 includes a mounting bracket 210 fixedly connected inside the refrigerator 100. Both the top and bottom ends of the mounting bracket 210 have aligned placement holes 211. A first adjusting screw 220 is rotatably connected to the top of the mounting bracket 210. The rod of the first adjusting screw 220 extends through the inner side of the mounting bracket 210. A mounting frame 230 aligned with the placement hole 211 is threadedly connected to the rod of the first adjusting screw 220. A surrounding frame is fixedly connected between the mounting frame 230 and the upper placement hole 211. Positioning springs 240 are arranged in a ring around the centerline of the placement hole 211; the horizontal cross-sectional shape of the upper placement hole 211 is circular, and the horizontal cross-sectional shape of the lower placement hole 211 is rectangular, with the lower placement hole 211 having a larger horizontal cross-sectional dimension than the upper placement hole 211; a support mesh 250, which is made of nylon material, is embedded inside the lower placement hole 211; the vertical cross-sectional shape of the positioning springs 240 is V-shaped, with the V-shaped opening of the positioning springs 240 facing away from the centerline of the placement hole 211.

[0032] A flexible sealing sleeve 260 is fixedly connected between the mounting frame 230 and the upper placement hole 211. Positioning springs 240 are distributed in a ring on the outside of the flexible sealing sleeve 260. The flexible sealing sleeve 260 is hourglass-shaped and is made of silicone material. A guide rod 270 is inserted into the bottom of the mounting frame 230. The top of the guide rod 270 passes through the mounting frame 230 and is fixedly connected to the mounting bracket 210. The inner bottom wall of the refrigerator 100 has threaded grooves 120 that are staggered with the ice pack placement cavity 110. A connecting screw 280 is rotatably connected to the top of the mounting bracket 210. The bottom of the connecting screw 280 passes through the mounting bracket 210 and is threadedly connected to the threaded groove 120.

[0033] In this embodiment, when the refrigerator 100 is used for the first time, the connecting screw 280 is first manually unscrewed. The connecting screw 280 causes the mounting bracket 210 to separate from the refrigerator 100. At this time, the ice pack placement cavity 110 is exposed. The sampling personnel can then place the corresponding number of ice packs into the ice pack placement cavity 110. Then, the positioning and storage mechanism 200, which can lock the corresponding size sampling bottle, is inserted into the refrigerator 100. Then, the connecting screw 280 in the positioning and storage mechanism 200 is tightly threaded into the threaded groove 120. Finally, a rubber sealing plug with a diameter larger than the upper placement hole 211 is inserted into the unused upper placement hole 211 (the rubber sealing plug is a common flexible sealing device and is a well-known technology known to those skilled in the art, so it is not shown in the accompanying drawings). This makes the rubber sealing plug block the upper placement hole 211 and prevent the cold air inside the mounting bracket 210 from escaping from the upper placement hole 211.

[0034] Working principle: When the sampling personnel need to place the sampling bottle containing the sampled water into the refrigerator 100, first remove the rubber sealing plug at the corresponding position, then manually rotate the adjusting screw 220. The adjusting screw 220 drives the mounting frame 230 to move vertically downward along the guide rod 270. The mounting frame 230 vertically pulls the positioning spring 240 and the flexible sealing sleeve 260 downward until the minimum inner diameter of the flexible sealing sleeve 260 matches the diameter of the sampling bottle. Then, the personnel pass the sampling bottle through the inside of the flexible sealing sleeve 260 until the bottom of the sampling bottle is in contact with the support net 250. Then, manually rotate the adjusting screw 220 again. The adjusting screw 220 drives the mounting frame 230 to move upward along the guide rod 270. 230 vertically compresses the positioning spring 240 and the flexible sealing sleeve 260 upwards. The positioning spring 240 drives the flexible sealing sleeve 260 to indent inwards until it is tightly abutting against the surface of the sampling bottle. At this time, the ice pack inside the ice pack placement cavity 110 can cool the sampling bottle and the sampled water through the gap between the sampling bottle and the lower placement hole 211. In addition, the flexible sealing sleeve 260 can not only flexibly seal the gap between the sampling bottle and the upper placement hole 211 to reduce the external heat from entering the inner side of the mounting frame 210 through the gap, thereby reducing the uneven temperature inside the mounting frame 210, but also flexibly position the sampling bottle to reduce the probability of the sampling bottle being damaged by bumps and collisions during transportation.

[0035] It should be noted that the refrigerator box 100 mentioned above is a device with relatively mature existing technology. The specific model can be selected according to actual needs, and will not be elaborated here.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
