Description

Technical Field

[0001] The present invention relates to a core box, and more particularly to a multi-functional core box. Background Art

[0002] A core box is a container for storing cores taken out from drilling. In geological surveys such as hydrology and mining, the cores taken out from boreholes are placed in the core box in sequence and stored as important geological archive materials for a long time, providing accurate and reliable data for mine exploration, research on deep resources or engineering geological conditions.

[0003] Most of the existing core boxes are open boxes made of materials such as plastics and woods, which are convenient for observing and placing cores. However, the existing open core boxes expose the cores to the air during long-term sample storage, and are easily affected by the external air and weathering occurs. Especially for cores such as argillaceous sandstone and mudstone with poor hydro-physical properties, they often disintegrate after being exposed for a period of time, affecting core testing; in addition, when testing, measuring tools such as tape measures or straight rulers are required each time to measure the length, which is inconvenient to operate. Therefore, how to design a multi-functional core box that can directly read the length and prevent core weathering is an important problem to be solved in the geological survey industry. Summary of the Invention

[0004] The purpose of the present invention is to provide a multi-functional core box, which can not only achieve vacuum preservation of cores, reduce the influence of the external environment on the cores, extend the storage time of the cores, but also facilitate the observation of the cores and reduce the number of times of opening the box.

[0029] The following will describe the embodiments of the present invention in detail with reference to the drawings. The embodiments are implemented on the premise of the technical solution of the present invention, and detailed implementation manners and specific operation processes are given. However, the protection scope of the present invention is not limited to the following embodiments.

[0030] As Figures 1-4 shown, the multifunctional core box of the present invention includes

[0031] a core box body 1, the core box body 1 is integrally cast, and the core box body 1 has an upper opening;

[0032] a box cover 2, which is hermetically buckled at the upper opening and one side of the box cover 2 is hinged to the core box body 1 through a hinge, and the box cover 2 and the core box body 1 enclose a storage space for storing the core;

[0033] A separation component, including a plurality of partition plates 3 arranged in the core box body 1 along the length direction of the core box body 1. The left and right side edges of each partition plate 3 are fixedly connected to the left and right side walls of the core box body 1 respectively, and there is a vertical gap between the partition plate 3 and the bottom wall of the core box body 1 to ensure that the following friction cloth 4 can move back and forth on the bottom wall of the core box body 1. The plurality of partition plates 3 are spaced front and back to divide the core box body 1 into a plurality of storage cavities, and each storage cavity can store one core.

[0034] An air inlet and outlet unit, arranged on the box cover 2, and the air inlet and outlet unit is communicated with the storage space for evacuating the storage space; and

[0035] A driving component, arranged at the bottom of the core box body 1, and the driving component drives the core to rotate in the storage cavity, so as to directly observe the core in the core box body 1 and reduce the number of times of opening the box.

[0036] As Figure 1 and Figure 4 shown, the driving component includes a first reel 5, rotatably arranged in the core box body 1 (the two end parts of the first reel 5 are rotatably connected to the left and right side walls of the core box body 1 through bearings), the first reel 5 is close to a long side of the core box body 1 and is parallel to the length direction of the core box body 1; a second reel 6, rotatably arranged in the core box body 1 (the two end parts of the second reel 6 are rotatably connected to the left and right side walls of the core box body 1 through bearings), the second reel 6 is close to the other long side of the core box body 1 and is parallel to the length direction of the core box body 1, and the first reel 5 and the second reel 6 are spaced front and back; and a friction cloth 4, laid on the bottom wall of the core box body 1, one end part of the friction cloth 4 is wound around the first reel 5 and the other end part is wound around the second reel 6. During operation, the friction cloth 4 can be driven to move on the bottom wall of the core box body 1 by rotating the first reel 5 and the second reel 6. Due to the large friction force between the friction cloth 4 and the core, the core can be driven to rotate in its corresponding storage cavity during the movement of the friction cloth 4, so as to facilitate the observation of the core.

[0037] As Figure 1 shown, the outer ends of the first reel 5 and the second reel 6 are both provided with easy-to-operate cranks 7. By rotating the crank 7 on the first reel 5 and the crank 7 on the second reel 6, the friction cloth 4 can move back and forth in the core box body 1, thereby driving the core to rotate in the storage cavity, and the operation is simple and convenient.

[0038] As Figure 3 shown, a sealing ring 8 is arranged between the box cover 2 and the core box body 1, which improves the sealing performance of the core box body 1 and the box cover 2, ensures the vacuum holding time, and thus extends the storage time of the core.

[0039] As Figure 2As shown, the air inlet and outlet unit is the air inlet and outlet valve 9 provided on the box cover 2. After the core is stored, the air inlet and outlet valve 9 is externally connected to a negative pressure pump to extract negative pressure from the storage space, store the core in a vacuum state, reduce the influence of the air environment on the core, and extend the storage time of the core; when core sampling and testing or further analysis are required, gas can be supplemented into the storage space through the air inlet and outlet valve 9 and ensure that the gas in the storage space is lower than the local atmospheric pressure, and then the box body is opened; after the core is tested, the core is stored in the original storage order, and then negative pressure is extracted to achieve long-term storage of the core.

[0040] As Figure 1 shown, a pair of handles 10 for easy gripping are provided on the outer sides of the left and right side walls of the core box body 1, which is convenient for operation and facilitates the flexible transfer of the core box body 1.

[0041] During actual processing, the box cover 2 is a transparent cover made of high-strength organic glass material, which not only facilitates observing the core through the box cover 2, but also can ensure the structural strength.

[0042] As Figure 2 shown, a scale line extending along its length direction is provided on the upper part of each partition plate 3, which can directly read the length data of the core and simplifies the operation.

[0043] During use, the cores are sequentially placed in the storage cavity in order; when the core box body 1 is filled with cores, cataloging is carried out in a timely manner; the box cover 2 is hermetically covered at the upper edge of the core box body 1 to achieve the sealed connection between the box cover 2 and the core box body 1; then the air inlet and outlet valve 9 is connected to an external negative pressure device (such as a negative pressure pump), and the negative pressure device is used to extract vacuum, so that the cores are stored in a vacuum environment for a long time, extending the storage time of the cores and reducing the probability of weathering or disintegration of the cores. When further observation of the cores is required later, the first reel 5 and the second reel 6 can be rotated to drive the friction cloth 4 to move back and forth on the bottom wall of the core box body 1. When the friction cloth 4 moves, it drives the cores to rotate in their respective storage cavities, so as to facilitate observing the cores along the circumferential direction of the cores and reducing the number of times of opening the cover. When the cores need to be tested later, the air inlet and outlet valve 9 can be connected to an external inflation device. When inflating, to ensure the integrity of the cores, the internal pressure of the core box body 1 is slightly lower than the local atmospheric pressure after inflation, and then the box cover 2 can be opened for testing.

[0044] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain in a specific posture (such as in the attached Figure 1The relative positional relationship, movement conditions, etc. among the components under the shown (conditions). If the specific posture changes, the directional indication also changes accordingly. In the present invention, unless otherwise clearly specified and defined, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] In addition, in the present invention, descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features.
