Description

Technical Field

[0001] This application relates to the field of coalfield exploration technology, specifically to a core collection device for coalfield geological drilling. Background Technology

[0002] In coalfield drilling operations, collecting and transporting core samples after drilling is a crucial step, as it affects subsequent research and analysis. However, current core collection devices generally suffer from a significant problem: the core collection tank size is fixed and cannot be flexibly adjusted. Such fixed-size core collection devices can only collect cores of specific pore sizes, resulting in significant limitations. To collect cores of different pore sizes, multiple core collection devices of different sizes are often required, which not only wastes equipment resources but also greatly increases equipment procurement costs and storage space requirements.

[0003] In actual coalfield drilling operations, drilling locations are varied and working environments are complex. Frequently changing and transporting core collection devices of different sizes consumes significant manpower, material resources, and time, severely impacting work efficiency and hindering the convenience and efficiency of field operations. Therefore, developing a device that can flexibly adjust its size and adapt to the needs of core collection with various borehole diameters has become a critical issue that urgently needs to be addressed in the current coalfield drilling field. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a core collection device for coalfield geological drilling.

[0005] This application provides a core collection device for coalfield geological drilling, including...

[0006] The enclosure includes a rectangular base plate and side plates perpendicular to the base plate;

[0007] The side plate includes a long side plate extending along a first direction and a short side plate extending along a second direction, and the long side plate and the short side plate are perpendicular to each other.

[0008] The positioning mechanism is located at the four corners of the base plate and includes mutually matching positioning seats and positioning blocks;

[0009] The positioning seat has an L-shaped cross-section, and the bending direction is the same as that of the side plate.

[0010] The cross-section of the positioning block is in the positive direction, located on the side of the positioning seat away from the side plate, and the side of the positioning block that is relatively away from the positioning seat is on the same plane as the end face of the positioning seat.

[0011] A separating mechanism, the separating mechanism comprising a positioning plate detachably mounted between two adjacent positioning mechanisms and a partition plate bridging two opposing rows of positioning plates.

[0012] Furthermore,

[0013] The positioning seat is installed at a distance from the side plate to form a temporary storage cavity for storing excess partitions;

[0014] The distance between the end faces of two adjacent positioning seats on the side closest to each other is an integer multiple of the width of the partition, which is used to lay the partition flat and form a complete plane;

[0015] The width of the partition is matched with the height of the side plate.

[0016] Furthermore,

[0017] The distance between the positioning block and the positioning seat is the same as the thickness of the positioning plate, and is used to snap the two ends of the positioning plate together.

[0018] A support platform is also provided between the positioning seat and the positioning block corresponding to the positioning plate, for supporting and positioning the positioning plate;

[0019] The support platform is fixedly installed on the base plate and is integrally formed with the positioning seat and positioning block.

[0020] Furthermore,

[0021] The partition includes a relatively long partition and a relatively short partition, which are used to form core storage cavities in different directions within the box.

[0022] The width of the long partition is greater than the width of the short partition, which is used to form the core storage cavities of different widths.

[0023] Furthermore,

[0024] The long partition and the short partition each have through holes at both ends corresponding to the positioning plate, for through-engaging with the positioning plate.

[0025] Furthermore,

[0026] The positioning plate includes a long positioning plate with a relatively long length and a short positioning plate with a relatively short length;

[0027] The width of the long positioning plate is significantly smaller than the width of the short positioning plate, and it is used to be installed in correspondence with the short partition and the long partition.

[0028] Furthermore,

[0029] The long positioning plate has a first slot on the end face away from the base plate;

[0030] The number of the first slots includes multiple slots, which are evenly arranged along the extension direction of the long positioning plate, and are used to engage and position the short partition, with adjustable spacing.

[0031] Furthermore,

[0032] The short positioning plate has a second slot on the end face away from the base plate;

[0033] The second slot includes multiple slots, which are evenly arranged along the extension direction of the short positioning plate, and are used to engage and position the long partition plate with adjustable spacing.

[0034] Furthermore,

[0035] The arrangement interval of the first slot is relatively smaller than that of the second slot, which is used to form the core storage cavity of different ranges.

[0036] The advantages and positive effects of this application are:

[0037] This technical solution sets positioning mechanisms at the four corners of the box, and with the detachable positioning plates, partitions can be set at intervals along the first or second direction inside the box to form a core storage cavity for placing the core. At the same time, by changing the interval between the partitions, the width of the core storage cavity can be effectively controlled, thus making it suitable for cores of different sizes.

[0038] Furthermore, the partition has two sets of corresponding lengths for the side length of the box. When one set is used to form a core storage cavity, the other set can be laid directly on the bottom of the box, which will not affect the storage of the core or the carrying of it.

Detailed Implementation

[0043] To enable those skilled in the art to better understand the technical solution of this application, the application will be described in detail below with reference to the accompanying drawings. The description in this section is only exemplary and explanatory, and should not be used to limit the scope of protection of this application in any way.

[0044] Please refer to Figure 1-3 This embodiment provides a core collection device for coalfield geological drilling, including a box 100, which includes a rectangular bottom plate and side plates perpendicular to the bottom plate; the side plates include a long side plate extending along a first direction and a short side plate extending along a second direction, and the long side plate and the short side plate are perpendicular to each other; positioning mechanisms are located at the four corners of the bottom plate, including mutually matching positioning seats 200 and positioning blocks 210; the positioning seats 200 have an L-shaped cross-section, and the bending direction is the same as the bending direction of the side plates; the positioning blocks 210 have a positive cross-section, are located on the side of the positioning seats 200 away from the side plates, and the side of the positioning blocks away from the positioning seats 200 is on the same plane as the end face of the positioning seats 200; and a separating mechanism includes a positioning plate detachably installed between two adjacent positioning mechanisms and a partition plate bridging between two opposite rows of positioning plates.

[0045] In this embodiment, the box 100 is rectangular, and its length along the first direction and its length along the second direction are different. Therefore, partitions can be set inside the box 100 along the first direction or the second direction respectively, thereby forming core storage cavities of different lengths, which can be adapted to different usage needs.

[0046] In this embodiment, the positioning base 200 is L-shaped and cooperates with the square positioning block 210, forming a limiting cavity extending along the first direction and a limiting cavity extending along the second direction, respectively, so that the positioning plate can be installed along both the first direction and the second direction.

[0047] In a preferred embodiment, the positioning seat 200 is installed at a distance from the side plate to form a temporary storage cavity for storing excess partitions; the distance between the end faces of two adjacent positioning seats 200 on the side closest to each other is an integer multiple of the width of the partition, for laying the partition flat and forming a complete plane; the width of the partition matches the height of the side plate.

[0048] In this embodiment, the positioning seat 200 is installed at intervals with the side plate, so that temporary storage cavities are formed between the four side walls of the box 100 and the positioning seat 200 respectively; the number of partitions carried by each box 100 is fixed. When the diameter of the rock core is relatively large, the number of partitions required will be reduced. At this time, the remaining partitions can be put into the temporary storage cavity, thereby realizing the function of easy carrying.

[0049] In a preferred embodiment, the distance between the positioning block 210 and the positioning seat 200 is the same as the thickness of the positioning plate, which is used to snap the two ends of the positioning plate together; a support platform 220 is also provided between the positioning seat 200 and the positioning block 210 corresponding to the positioning plate, which is used to support and position the positioning plate; the support platform 220 is fixedly installed on the base plate and is integrally formed with the positioning seat 200 and the positioning block 210.

[0050] In this embodiment, the support platform 220 is fixedly installed on the bottom plate of the box 100 and is integrally formed with the positioning block 210 and the positioning seat 200. By setting the support platform 220, the installation height of the positioning plate can be effectively limited, so that the positioning plate is suspended and installed, which facilitates the docking between partitions.

[0051] In a preferred embodiment, the partition includes a relatively long long partition 300 and a relatively short short partition 310, for forming core storage cavities in different directions within the housing 100; the width of the long partition 300 is greater than the width of the short partition 310, for forming core storage cavities of different widths.

[0052] In this embodiment, the length of the long partition 300 matches the distance between the two relatively shorter side panels of the box 100; the length of the short partition 310 matches the distance between the two relatively longer side panels of the box 100.

[0053] In this embodiment, the width of the long partition 300 is relatively smaller than the width of the short partition 310. Since the partitions are laid at the bottom of the box 100 during storage, the width of the partitions directly affects the number of partitions. The number of partitions, in turn, directly affects the distance between adjacent partitions. Therefore, when the diameter of the core is relatively small, the long partition 300 can be selected for separation; when the diameter of the core is relatively large, the short partition 310 should be selected for separation. Similarly, the width of the long partition 300 can also be relatively larger than the width of the short partition 310, and the appropriate partition can be selected accordingly.

[0054] In a preferred embodiment, the long partition 300 and the short partition 310 are respectively provided with through holes 340 at both ends corresponding to the positioning plate, for through engagement with the positioning plate.

[0055] In a preferred embodiment, the positioning plate includes a relatively long long positioning plate 320 and a relatively short short positioning plate 330; the width of the long positioning plate 320 is significantly smaller than the width of the short positioning plate 330, and is used to be installed in correspondence with the short partition plate 310 and the long partition plate 300.

[0056] In this embodiment, the two ends of the long partition 300 are sleeved and installed on the short positioning plate 330; the two ends of the short partition 310 are sleeved and installed on the long positioning plate 300; therefore, the width of the long positioning plate 320 is relatively smaller than the width of the short positioning plate 330, thereby satisfying the structural setting that the width of the short partition 310 is relatively small and the through hole 340 is relatively small.

[0057] In a preferred embodiment, the long positioning plate 320 has a first slot 321 on the end face away from the base plate; the number of the first slots 321 includes multiple slots, which are evenly arranged along the extension direction of the long positioning plate 320, and are used to snap and position the short partition 310 with adjustable spacing.

[0058] In this embodiment, a first slot 321 is provided on the top surface of the long positioning plate 320 so that the short partition 310 can be engaged with the long positioning plate 320 through the through hole 340. By providing multiple and evenly arranged first slots 321, multiple short partitions 310 can be installed, and the distance between two adjacent partitions 310 can be adjusted.

[0059] In a preferred embodiment, the short positioning plate 330 has a second slot 331 on the end face away from the base plate; the number of the second slots 331 includes multiple slots, which are evenly arranged along the extension direction of the short positioning plate 330, and are used to engage and position the long partition 300 with adjustable spacing.

[0060] In a preferred embodiment, the arrangement interval of the first slot 321 is relatively smaller than the arrangement interval of the second slot 331, so as to form the core storage cavity of different ranges.
