Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, and in particular to a device for collecting and storing snow samples at different depths. Background Technology

[0002] Research on snow samples involves various aspects, including the content of various physical properties, trace elements and organic pollutants, and the ecological or physiological analysis of microbial communities in the snow. Snow at different depths at the same location, as well as snow at the same depth at different locations, can reveal different information. Currently, many studies use snow shovels for snow sampling. However, methods for collecting snow samples at various depths are limited, and the collected snow samples cannot be used to study continuous longitudinal information. Furthermore, in some studies, it is necessary to preserve the in-situ characteristics of the snow; transferring it to other containers often destroys relevant properties.

[0003] In current field collection practices for snow cover, existing snow sample collection devices are usually of fixed length, which makes it difficult to adapt to the sampling needs of snow cover at different depths and is not convenient for conducting continuous longitudinal information studies on in-situ samples at different depths. Therefore, a device that can meet the requirements of snow sample collection and preservation at different depths is proposed. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing technologies are not convenient for conducting continuous longitudinal information research on in-situ samples at different depths, and to propose a device for collecting and preserving snow samples at different depths.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for collecting and storing snow samples at different depths includes multiple collection tubes that are detachably connected to each other. A rotating handle is detachably connected to the top end of each collection tube, and a cutting tube is detachably connected to the bottom end of each collection tube.

[0007] A cutting blade is rotatably connected to the outer surface of the cutting tube, and extension plates are fixedly connected to both ends of the cutting blade. A pull rope is fixedly connected to the outer end of the extension plate.

[0008] The two ends of the collection tube are detachably connected to end caps for sealing the collection tube.

[0009] Preferably, the lengths of the collection tubes are 10cm, 20cm, and 50cm.

[0010] Preferably, the detachable connections between the plurality of collection tubes, as well as between the collection tubes and the rotating handle, and between the end caps and the cutting tubes and the collection tubes, are threaded connections.

[0011] Preferably, the detachable connections between the plurality of collection tubes, as well as between the collection tubes and the rotating handle, and between the end caps and the cutting tubes and the collection tubes, are magnetic connections.

[0012] Preferably, the materials of the collection tube, the rotating handle, and the cutting tube are stainless steel.

[0013] Preferably, the width of the cutting blade is at least 10 mm.

[0014] Preferably, the wall thickness of the collection tube is in the range of 0.5 mm to 1 mm, and the inner diameter of the collection tube is 30-50 mm.

[0015] Preferably, the end cap is made of polypropylene.

[0016] Compared with the prior art, this utility model provides a device for collecting and storing snow samples at different depths, and has the following beneficial effects:

[0017] 1. This utility model involves breaking the collected snow column into sections according to the cross-section of each collection tube, and sealing both ends of the collection tube with end caps, thus directly transforming the collection tube into an in-situ preservation device. This facilitates independent analysis and research of snow samples at different depths, avoids secondary contamination and information loss during snow sample transfer, and ensures the accuracy and reliability of research data.

[0018] 2. This utility model allows for the rapid and uniform extraction of snow samples by applying downward drilling force through rotating the handle, reducing operational difficulty and labor intensity. The combined use of the cutting tube and cutting blade, by pulling the rope upwards, rotates the cutting blade to the bottom of the cutting tube, and then rotating the handle to separate the snow sample from the snow, makes the sampling process smoother and avoids jamming in the snow. The cutting blade is located directly below the snow sample, and after collection, it is also convenient to pull out the snow sample when the rotating handle is pulled upwards.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0025] Reference Figures 1-3 A device for collecting and preserving snow samples at different depths includes multiple detachably connected collection tubes 2. A rotating handle 1 is detachably connected to the top of each collection tube 2, and a cutting tube 3 is detachably connected to the bottom of each collection tube 2. A cutting blade 4 is rotatably connected to the outer surface of the cutting tube 3. Extension plates 5 are fixedly connected to both ends of the cutting blade 4, and a pull rope 7 is fixedly connected to the outer end of the extension plates 5. End caps 6 are detachably connected to both ends of the collection tubes 2 for sealing. In use, a downward drilling force is applied by rotating the handle 1, allowing for rapid and uniform extraction of snow samples, reducing operational difficulty and labor intensity. The cutting tube 3 and cutting blade 4 work together by pulling the pull rope 7 upwards, rotating the cutting blade 4 to the bottom of the cutting tube 3, and then rotating the handle 1 again to extract the snow sample using the cutting blade 4. The separation of snow samples in the middle makes the sampling process smoother and avoids jamming in the snow. The cutting blade 4 is located directly below the snow sample. After collection, it is easy to pull out the snow sample when rotating the handle 1 upward. Through modular design, multiple collection tubes 2 can be assembled into different lengths and can be reused to meet the collection of snow samples at different depths. The collected snow column can also be separated according to the cross-section of each collection tube 2 to turn the entire collection tube or the individual small collection tubes after disassembly and cutting into an in-situ preservation device. This facilitates the study of continuous physical or geochemical information of the longitudinal profile of the in-situ snow sample or snow column. The sealing structure of the end cap 6 ensures that the snow sample remains in situ during transportation, which greatly facilitates the subsequent study of continuous physical or geochemical information of the longitudinal profile of the in-situ snow sample or snow column.

[0026] The lengths of the collection tubes 2 are 10cm, 20cm and 50cm respectively. The variety of collection tubes 2 and the combination of different lengths increase the ways to obtain snow samples of different lengths, which further facilitates the acquisition of continuous physical or geochemical information of the longitudinal profile of snow columns at different depths.

[0027] The detachable connections between multiple collection tubes 2, as well as between collection tube 2 and rotating handle 1, end cap 6 and cutting tube 3 and collection tube 2, are threaded connections. The detachable connections between multiple collection tubes 2, as well as between collection tube 2 and rotating handle 1, end cap 6 and cutting tube 3 and collection tube 2, are magnetic connections. The threaded or magnetic connection methods are quick-connect structures, ensuring the convenience and stability of collection tube 2 during assembly and disassembly, and also facilitating storage and carrying.

[0028] The materials of the collection tube 2, the rotating handle 1 and the cutting tube 3 are stainless steel. The width of the cutting blade 4 is at least 10mm. After collection, the cutting blade 4 of a certain width can better bring out the snow column when it is pulled up.

[0029] The wall thickness of the collection tube 2 ranges from 0.5 mm to 1 mm, and the inner diameter of the collection tube 2 is 30-50 mm. The wall thickness of 0.5-1.0 mm ensures the lightness and strength of the collection tube, making it easy to carry and operate. The inner diameter of 30-50 mm ensures that the collected snow column samples are sufficiently representative.

[0030] The end cap 6 is made of polypropylene, which has good low-temperature resistance, ensuring that the end cap 6 will not deform during use in low-temperature environments.

[0031] In this invention, 1. The collected snow column is broken and separated according to the cross-section of each collection tube 2, and the two ends of the collection tube 2 are sealed with end caps 6, so that the collection tube 2 is directly transformed into an in-situ preservation device, which facilitates independent analysis and research of snow samples at different depths, avoids secondary pollution and information loss during the snow sample transfer process, and ensures the accuracy and reliability of research data.

[0032] 2. By applying downward drilling force through rotating handle 1, snow samples can be drilled quickly and evenly, reducing operational difficulty and labor intensity. The combined use of cutting tube 3 and cutting blade 4, pulling the pull rope 7 upward, rotates the cutting blade 4 to the bottom of the cutting tube 3, and then rotating handle 1, uses the cutting blade 4 to separate the snow sample from the snow, making the sampling process smoother and avoiding jamming in the snow. The cutting blade 4 is located directly below the snow sample, and after collection, it is also convenient to pull out the snow sample when rotating handle 1 is pulled upward.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
