Description

Technical Field

[0001] The utility model relates to the technical field of soil sample preservation boxes, in particular to a soil sampling and preservation device for water conservancy projects. Background Art

[0002] The water conservancy project soil sampling and preservation device is a professional equipment used to collect, preserve and transport soil samples at water conservancy project sites. It plays a vital role in ensuring the integrity, representativeness and reliability of soil samples, providing a safe and stable storage environment for soil samples, and helping to prevent samples from being contaminated, damaged or deteriorated during transportation or storage. The water conservancy project soil sampling and preservation device usually consists of a durable outer shell and a well-sealed inner container. The outer shell is usually made of high-strength materials such as metal or hard plastic to withstand bumps and impacts during transportation, providing accurate and reliable soil sample data for subsequent laboratory analysis and data processing.

[0003] The patent with the announcement number CN210391968U currently discloses a soil sample preservation box, including a sampling bottle cap, a sampling bottle body and a positioning seat; one end of a spring a is fixedly connected to the top of the pressure cap; the sampling bottle cap is threadedly screwed on the top of the sampling bottle body; the sampling bottle body is interference-fitted into the interior of the positioning seat; the above device solves the problem that the container for holding samples in the existing soil preservation box cannot buffer the shaking generated during transportation.

[0004] However, the above scheme still has the following problems: when using the same collection spoon to collect soil samples at different locations, it is easy to bring soil residues from the previous location to the next location, causing cross-contamination between different soils. This contamination will not only affect the accuracy and representativeness of the samples, but may also interfere with subsequent laboratory analysis and data processing, making it difficult to accurately trace the source and collection information of each sample.

[0008] Furthermore, a sealing block is installed at the bottom of the top cover, and the outer side of the sealing block is fitted and connected to the inner wall of the glass tube.

[0009] Furthermore, a bottom plate is installed in the middle of the inner wall of the bottom shell, and the outer side of the bottom plate is fixedly connected to the inner wall of the bottom shell.

[0010] Furthermore, a sealing pad is arranged in the spoon box, the sealing pad is fitted and connected to the inner wall of the spoon box, and a buckle groove is arranged on the surface of the sealing pad.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model prevents soil sample contamination and cross contamination by equipping each internal container with a built-in sampling spoon and a sealing cover. During the sampling and storage process, the soil sample may be contaminated by external impurities or other soil samples. The sealing cover can ensure that the soil sample in each container exists independently, avoiding cross contamination between different soil samples and ensuring the reliability of the experimental results. Each soil sample has an independent sampling spoon, which will further avoid cross contamination between different samples. During the sampling process, there may be a risk of contamination between different samples, and the use of a built-in sampling spoon can ensure the independence of each sample and improve the reliability of the experimental results.

[0019] The technical solutions in the embodiments of the present invention will be described in detail and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] like Figures 1 to 5 As shown, a soil sampling and preservation device for a water conservancy project includes a box body 1 and a plurality of sampling tank assemblies 2 arranged in the box body 1. The sampling tank assembly 2 is composed of a top cover 201, a glass tube 202, a bottom shell 203 and a spoon box 204 spliced ​​end to end. The various components of the sampling tank assembly 2 can be separately arranged, and a sampling spoon 4 is arranged in the spoon box 204.

[0021] like Figure 1 As shown, a water conservancy project soil sampling and storage device in the utility model is similar to the existing soil sample storage box structure, such as the soil sample storage box disclosed in the patent publication number CN210391968U. The main improvement of the utility model is to effectively avoid cross contamination, maintain sample integrity, and improve sampling and management efficiency. Figures 1 to 5 As shown, when a soil sampling and preservation device for water conservancy projects in the utility model is used, the detachable design of the sampling tank assembly 2 makes the assembly and disassembly of the device very convenient. During the sampling process, the sampling personnel can quickly assemble or disassemble the sampling tank assembly 2 as needed to adapt to different sampling environments and requirements. This flexibility greatly improves work efficiency and also facilitates subsequent sample processing and analysis. The sampling spoon 4 arranged in the spoon box 204 provides convenience for the sampling personnel. The presence of the sampling spoon 4 enables the sampling personnel to directly and accurately obtain the required samples from the soil without having to find or carry additional tools. This not only simplifies the sampling process, but also improves the accuracy and reliability of sampling. The glass tube 202 As the main part of the sampling tank, it has the characteristics of transparency, easy cleaning, and corrosion resistance, which enables the soil sample to maintain its original state during the storage process and is not easily affected by the external environment. At the same time, the glass tube 202 can also clearly display the color, texture and other characteristics of the sample, which is convenient for sampling personnel to observe and record. The design of the top cover 201 and the bottom shell 203 also plays a protective role. The top cover 201 can tightly seal the glass tube 202 to prevent the sample from being contaminated by the outside world or water evaporation during the storage process. The bottom shell 203 serves as the main storage part of the sample. The design of the spoon box 204 not only provides space for storing the sampling spoon 4, avoiding the loss and contamination of the sampling spoon 4, but also makes the sampling process more convenient and quick.

[0022] like Figure 4 As shown, the inner wall of the top cover 201 and the outer top of the glass tube 202 are threadedly connected, the outer bottom of the glass tube 202 and the inner top wall of the bottom shell 203 are threadedly connected, and the inner bottom wall of the bottom shell 203 and the outer top of the spoon box 204 are threadedly connected.

[0023] By setting up the threaded connection between the top cover 201, the glass tube 202, the bottom shell 203 and the spoon box 204, the sampling tank assembly 2 forms a closed and stable system, which effectively prevents the leakage and damage of the soil sample during storage and transportation. The glass tube 202 allows the sampler to intuitively observe the state of the sample, including color, humidity, texture, etc. The threaded connection between the top cover 201 and the glass tube 202 ensures tightness and stability.

[0024] like Figure 4 As shown, a sealing block 205 is installed at the bottom of the top cover 201 , and the outer side of the sealing block 205 is closely connected to the inner wall of the glass tube 202 .

[0025] The design of setting the sealing block 205 makes the connection between the top cover 201 and the glass tube 202 tighter, effectively reducing possible air and moisture exchange. This enhanced sealing performance prevents the sample from being contaminated or dried out during the storage process. The outer side of the sealing block 205 is tightly connected to the inner wall of the glass tube 202 to form a closed environment, reducing the risk of sample leakage from the sampling tank assembly 2.

[0026] like Figure 4 As shown, a bottom plate 206 is installed at the middle position of the inner wall of the bottom shell 203 , and the outer side of the bottom plate 206 is fixedly connected to the inner wall of the bottom shell 203 .

[0027] Specifically, by such a configuration, the bottom plate 206 provides a flat and stable surface, so that a groove for placing samples is formed inside the bottom shell 203 , so that the samples can be placed in a centralized manner and avoid being scattered around inside the sampling tank assembly 2 .

[0028] like Figures 4 to 5 As shown, a sealing gasket 3 is provided in the spoon box 204 , the sealing gasket 3 is fitted and connected to the inner wall of the spoon box 204 , and a buckle groove 301 is provided on the surface of the sealing gasket 3 .

[0029] With this arrangement, the sealing gasket 3 fits tightly against the inner wall of the spoon box 204 to form an effective sealing layer, which prevents external air, moisture or other contaminants from entering the spoon box 204, thereby maintaining the purity and stability of the sample in the spoon box 204. By removing the sealing gasket 3 through the buckle groove 301, unnecessary damage or deformation of the sealing gasket 3 during operation can be avoided, which helps to maintain the integrity and sealing performance of the sealing gasket 3 and ensure that it can effectively prevent external contaminants from entering the spoon box 204.
