Description

Technical Field

[0001] This invention relates to the field of soil sample testing tools, specifically a multifunctional soil column sample container suitable for CT scan imaging. Background Technology

[0002] In soil science research, PVC pipes are commonly used to collect undisturbed soil columns. CT scanning imaging is a technique that uses rays to penetrate objects and image their interiors. The collected undisturbed soil columns can be imaged using CT scanning for further analysis of soil structural characteristics, and it is now widely used in soil sample analysis and testing.

[0003] A search of patent publication number CN208636068U, entitled "A Sample Collection and Measurement Container for Soil Moisture," reveals that the container includes a soil sampling container, a top cover, and an auxiliary outer cylinder. The top cover has a fine internal thread on its inner wall and a sealing ring at the top to prevent moisture loss from the soil sample. The soil sampling container is a hollow cylinder with an open top and a wide external thread on its outer wall. The auxiliary outer cylinder is a cylindrical tube extending through both ends, with a wide internal thread on its inner wall that mates with the wide external thread, and a fine external thread on its top outer edge that mates with the fine internal thread. The auxiliary outer cylinder is fitted onto the soil sampling container, with the wide external thread and the wide and fine threads engaging in a threaded connection. The top of the soil sampling container is higher than the top of the auxiliary outer cylinder, and the fine internal thread and the fine external thread... The top cover is threadedly connected to the auxiliary outer cylinder, and the top of the soil sampling container abuts against the sealing ring. The soil column sample container in the above scheme is used to protect the batch of soil samples through a sealing structure. However, because multiple soil column containers are scanned simultaneously during soil column scanning to ensure scanning accuracy and efficiency, it is difficult to align different soil column containers. Only with strict alignment can the differences in soil structure characteristics of the same soil layer be compared. Furthermore, the number of soil column containers scanned simultaneously each time may be different. During scanning and stacking, the lack of a fixed and easily disassembled structure makes the scanning process less stable, resulting in different scanning radiation received by the scanned samples and affecting the accuracy of the scanning results. Summary of the Invention

[0004] The purpose of this invention is to provide a multifunctional soil column sample container suitable for CT scanning imaging, in order to solve the problem mentioned in the background art that it is difficult to align different soil column containers, because only strict alignment can compare the differences in soil structure characteristics of the same soil layer. The number of soil column containers scanned at the same time may be different each time. When stacking for scanning, the lack of a fixed structure that can be easily disassembled and assembled makes the scanning process less stable and affects the accuracy of the scanning results.

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

[0006] A multifunctional soil column sample container suitable for CT scanning imaging includes a fixed frame with handles fixedly connected to both sides. The fixed frame has multiple sleeves inside, and a PVC pipe containing a soil sample is placed inside each sleeve. Each sleeve includes an inner sleeve and an outer sleeve, and the distance between the inner and outer sleeves is adjustable.

[0007] Furthermore, the inner cylinder has threads on its surface, and the inner wall of the outer cylinder has threads that match the inner cylinder surface. The length of the sleeve can be adjusted through the cooperation between the threads.

[0008] Furthermore, the inner cylinder has a sliding groove on its surface, and limit grooves are provided on both sides of the sliding groove. A slider is fixed inside the outer cylinder, and the slider is adapted to the size of the sliding groove and the limit groove.

[0009] Furthermore, the length of the groove extends to the bottom end of the inner cylinder.

[0010] Furthermore, two reinforcing ribs are fixedly connected to the top of the outer arc wall of the sleeve, and an annular groove is formed between the two reinforcing ribs. The annular groove is adapted to be snapped with a snap ring. The snap ring is composed of two mirror-divided semi-arc strips. One snap ring is fixedly connected to a snap block on its outer arc wall, and the other snap ring is fixedly connected to a snap groove block. The snap block and the snap groove block are adapted to be inserted and limited. Limiting holes are opened through the opposite side walls of the snap groove block and the snap block. The limiting holes are adapted to be inserted with limiting posts.

[0011] Furthermore, the buckle ring is provided in two types, the first type having an angle of 180° between the buckle block and the buckle groove block, and the second type having an angle of 60° between the buckle block and the buckle groove block.

[0012] Furthermore, the ends of the two parts of the buckle ring are respectively fixedly connected with a plug and a slot, and the plug and the slot are adapted to be inserted into each other.

[0013] Furthermore, one end of the fixed frame is provided with an installation groove, the baffle is slidably connected to the inside of the installation groove, and the top of the baffle is provided with a through hole.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] In this invention, by placing the PVC pipe containing the soil column sample inside the sleeve, the surface of the sleeve can be marked to reduce errors. Then, the sleeve is placed inside the fixed frame, which makes it convenient to place the sleeve in advance when using it, saving some time. Moreover, the length of the sleeve can be adjusted to accommodate PVC pipes of different lengths, thus expanding the applicability of the device.

[0016] In addition, the sleeves in this invention are connected by a snap ring structure, with snap blocks and slot blocks set on the ring body. The two are mutually limited and connected, which facilitates the quick connection and alignment of multiple sleeves, making the soil column container scanning and placement more stable, improving the accuracy of detection, and different numbers of sleeves can be relatively fixed by the snap ring.

[0017] Secondly, a detachable baffle is installed at one end of the fixed frame. This allows the fixed frame to be tilted during use, causing the internal sleeves to abut against the inner wall of the baffle under gravity. This aligns the PVC pipes inside the multiple sleeves, ensuring consistent initial scanning positions and further improving the accuracy of the scanning results. Attached Figure Description

[0028] Please see Figure 1A multifunctional soil column sample container suitable for CT scanning imaging includes a fixed frame 1, with handles 6 fixedly connected to both sides of the fixed frame 1 to facilitate the movement of the fixed frame 1 and its internal parts. Multiple sleeves 2 are installed inside the fixed frame 1, and PVC pipes containing soil samples are placed inside the sleeves 2. After the soil sample is placed inside the sleeve 2, a marker can be used to mark the surface of the sleeve 2 to avoid data errors caused by discrepancies between the soil sample and the actual sample. Multiple fixed frames 1 and sleeves 2 can be set up on-site, allowing staff to arrange the sleeves 2 in advance and place them inside the fixed frame 1. Then, the fixed frame 1 and the sleeves 2 containing the soil sample can be moved together to the CT scanner using the handles 6. This avoids the need for staff to arrange the soil sample at the CT scanner before each scan, which not only wastes time but also easily leads to errors in the final soil sample test results due to incorrect marking.

[0029] like Figures 2 to 4 As shown, the sleeve 2 includes an inner cylinder 3 and an outer cylinder 4. The distance between the inner cylinder 3 and the outer cylinder 4 is adjustable, which makes it suitable for PVC pipes of different lengths (with soil samples placed inside) and expands the applicability of the device.

[0030] like Figure 2 As shown, it is a schematic diagram of the first embodiment of the adjustable sleeve 2. The inner cylinder 3 is provided with threads on its surface, and the inner wall of the outer cylinder 4 is provided with threads that match the surface of the inner cylinder 3. The adjustable length of the sleeve 2 is achieved through the cooperation between the threads.

[0031] like Figure 3 and Figure 4 As shown, it is a schematic diagram of another embodiment of the adjustable sleeve 2 and a partially enlarged schematic diagram. The inner cylinder 3 has a sliding groove 16 on its surface, and limit grooves 17 are provided on both sides of the sliding groove 16. The outer cylinder 4 has a slider 18 fixed inside. The slider 18 is adapted to the size of the sliding groove 16 and the limit groove 17. When it is necessary to adjust the distance between the inner cylinder 3 and the outer cylinder 4, the outer cylinder 4 is rotated to drive the slider 18 into the sliding groove 16. After moving the outer cylinder 4 to a suitable position, the outer cylinder 4 is rotated again to drive the slider 18 into the limit groove 17. This can fix the position between the inner cylinder 3 and the outer cylinder 4 relative to each other, so that they are fixed at a relative length.

[0032] In this embodiment, the length of the groove 16 extends to the bottom end of the inner cylinder 3, such as... Figure 4 As shown, this allows the slider 18 to be completely removed from the inside of the groove 16 during use, which facilitates subsequent cleaning of the inner cylinder 3 and the outer cylinder 4. It also makes it easy to replace a damaged part.

[0033] In this embodiment, the length of the sleeve 2 is adjustable through the cooperation between the sliding groove 16, the limiting groove 17 and the slider 18. Compared with the adjustment of the length of the sleeve 2 through the cooperation between the threads, the rotation range is smaller, and the length adjustment does not require continuous 360-degree rotation of the outer cylinder 4 or the inner cylinder 3. The operation is more convenient and the sleeve 2 is easier to use.

[0034] like Figures 3 to 7 As shown, two reinforcing ribs 7 are fixedly connected to the top of the outer arc wall of the sleeve 2. An annular groove 8 is formed between the two reinforcing ribs 7. A snap ring 9 is adapted to be snapped into the annular groove 8. The snap ring 9 is set in two parts and can be disassembled, making it more convenient to use. The snap ring 9 is composed of two mirror-divided semi-arc strips. One snap ring 9 is fixedly connected to a snap block 10 on its outer arc wall, and the other snap ring 9 is fixedly connected to a snap groove block 11. The snap block 10 and the snap groove block 11 are adapted to be inserted and limited. Through the mutual adaptation and insertion of the snap block 10 and the snap groove block 11, the soil column container can be quickly and conveniently assembled, which makes it more stable and accurate in subsequent scanning and detection.

[0035] In this embodiment, limiting holes 12 are provided through the opposite sidewalls of the slot block 11 and the slot block 10. The limiting holes 12 are adapted to be inserted into the limiting posts 13. The container is connected by sliding insertion, with the slot block 10 inserted into the slot of the slot block 11, and then the limiting posts 13 are inserted into the limiting holes 12. This allows for quick assembly and use of the soil column container, improving the stability of use. There are two types of buckle rings 9, with the first type having an angle of 180° between the slot block 10 and the slot block 11, and the second type having an angle of 6° between the slot block 10 and the slot block 11. 0°, because the soil column containers are stacked in a triangular shape, the column cylinders at the edge and the middle need to be connected by two types of opening angle blocks 10 and slot blocks 11 with a 90-degree and a 60-degree angle respectively. The ends of the two parts of the buckle ring 9 are respectively fixedly connected with the insert block 14 and the slot 15, and the insert block 14 and the slot 15 are adapted to be inserted. Through the insertion of the insert block 14 and the slot 15, it is convenient to assemble and fix the two parts of the buckle ring 9 into the ring groove 8, which facilitates the subsequent assembly and fixation of the soil column container and improves the convenience of use.

[0036] like Figure 8 As shown, a baffle 5 is installed at one end of the fixed frame 1. The baffle 5 fixes and seals the sleeve 2 of the soil column container, improving the stability and accuracy of subsequent scanning.

[0037] In this embodiment, a mounting groove 19 is provided at one end of the fixed frame 1, and the baffle 5 is slidably connected to the inside of the mounting groove 19 to realize the detachable assembly of the baffle 5. By setting the baffle 5, it is convenient to tilt the sleeve 2 inside the fixed frame 1 toward the baffle 5 by using the handle 6 during use. Then, due to gravity, one end of multiple sleeves 2 abuts against one side of the baffle 5, thereby aligning the PVC pipes inside multiple sleeves 2, making the initial scanning position consistent, and further improving the accuracy of the scanning results.

[0038] By making the baffle 5 detachable, it is easy to remove the baffle 5 from the inside of the fixed frame 1 after the sleeve 2 has completed the alignment work and before scanning begins, thereby reducing the interference of the baffle 5 during the scanning process. The top of the baffle 5 is provided with a through hole, which makes it easy to remove the baffle 5 from the inside of the mounting groove 19 by applying force to the through hole during use.

[0039] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
