Description

Technical Field

[0001] This utility model relates to the field of storage device technology, specifically a coalbed methane exploration sample storage device. Background Technology

[0002] Coalbed methane (CBM) is a gaseous resource associated with and coexisting with coal. It refers to hydrocarbon gases stored in coal seams, with methane as the main component, and belongs to unconventional CBM. However, since CBM exploration sites are not always flat, if the exploration site is relatively rugged, the collected CBM samples are easily dropped into the rugged terrain, causing impact damage to the storage devices and hindering their preservation.

[0003] Chinese utility model CN221858323U discloses a sample storage device for coalbed methane exploration. It features a clamping and fixing structure to prevent the sample bottle inside the shell from colliding with the inner wall of the shell when the shell is impacted. The principle is that by pressing the plug rod, the plug rod compresses the spring and retracts into the moving block. Then, the sample bottle is placed inside the shell. Finally, the electric push rod drives the moving block to move the clamping plate to clamp and fix the sample bottle.

[0004] However, existing devices have multiple moving blocks, requiring manual adjustment of each connector, which is cumbersome and inconvenient to use. Therefore, a sample storage device that is easy to clamp and fix is ​​designed to address the above-mentioned problems. Utility Model Content

[0031] Coalbed methane (CBM) is a gaseous resource associated with and coexisting with coal. It refers to hydrocarbon gases stored in coal seams, with methane as the main component, and belongs to unconventional CBM. However, since CBM exploration sites are not always flat, if the exploration site is relatively rugged, the collected CBM samples are easily dropped into the rugged terrain, causing impact damage to the storage devices and hindering their preservation.

[0032] In related technologies, pressing the connector rod causes it to retract into the moving block by compressing a spring. The sample bottle is then placed inside the housing, and finally, an electric actuator moves the moving block to move a clamping plate, thus securing the sample bottle. However, existing devices have multiple moving blocks, requiring manual adjustment of each connector rod, which is cumbersome and inconvenient to use.

[0033] To address some of the problems in related technologies, this application provides a coalbed methane exploration sample storage device. When it is necessary to store coalbed methane exploration samples, firstly, rotate the cover 12 to remove it from the top of the storage box 11, and then place the sample container inside the storage box 11. At this time, it is necessary to rotate the threaded rod 27. When rotating, because the threaded rod 27 is threadedly connected to the rectangular rod 25, and the bottom end of the rectangular rod 25 penetrates through the plate 21 and is restricted from rotating, the threaded rod 27 will be inserted into the rectangular rod 25 when rotating, and the rectangular rod 25 will move downward, pulling the connecting rod 26 to rotate. This causes the top end of the connecting rod 26 to pull the slider 23 to slide inside the slide groove 22, causing the clamping plate 24 to close, which can clamp and fix the cylindrical sample container. Finally, the cover 12 is threadedly rotated to connect the storage box 11.

[0034] This application is described below with reference to the accompanying drawings and specific embodiments:

[0035] Combination Figures 1-4 This application provides a coalbed methane exploration sample storage device, including: a storage box 11 with a lid 12 on its top, which is threadedly connected to the storage box 11; a clamping assembly 2 is provided inside the storage box 11, the clamping assembly 2 including: a plate 21 fixedly disposed on the inner wall of the storage box 11; a groove 22 opened on the top of the plate 21; a slider 23 slidably disposed inside the groove 22; a clamping plate 24 disposed on the top of the slider 23; a rectangular rod 25 with its bottom end penetrating through the plate 21; a connecting rod 26 with its top end hinged to the bottom end of the slider 23, and its bottom end hinged to the outer wall of the rectangular rod 25; and a threaded rod 27 with its top end penetrating through the bottom of the storage box 11 and inserted into the interior of the rectangular rod 25, and rotatably connected to the storage box 11 and threadedly connected to the rectangular rod 25.

[0036] When storing gas layer exploration samples, first rotate the cover 12 to remove it from the top of the storage box 11. Then, place the sample container inside the storage box 11. At this time, rotate the threaded rod 27. When rotating, because the threaded rod 27 is threadedly connected to the rectangular rod 25 and the bottom end of the rectangular rod 25 passes through the plate 21 and is restricted from rotating, the threaded rod 27 will be inserted into the rectangular rod 25 when it rotates. At the same time, the rectangular rod 25 will move downward and pull the connecting rod 26 to rotate. This will cause the top end of the connecting rod 26 to pull the slider 23 to slide inside the groove 22, causing the clamping plate 24 to close and clamp the cylindrical sample container. Finally, rotate the cover 12 to connect it to the storage box 11.

[0037] In some embodiments, the clamping assembly 2 further includes a rubber strip 241 disposed on the inner sidewall of the clamping plate 24.

[0038] When in use, the design of the rubber strip 241 can protect the sample container on the one hand, and the rubber material design increases friction, making it less likely for the clamp 24 to detach when holding the sample container.

[0039] In some embodiments, the clamping assembly 2 further includes a stop plate 251 disposed on the top of the rectangular rod 25.

[0040] The design of the support plate 251 allows for better support of the sample container when it is placed.

[0041] In some embodiments, the clamping assembly 2 further includes a baffle 271 disposed on the top of the threaded rod 27 and sliding inside the rectangular rod 25.

[0042] The design of the baffle 271 during use can prevent the threaded rod 27 from detaching from the rectangular rod 25 when it rotates, thus preventing the components from separating.

[0043] In some embodiments, the clamping assembly 2 further includes a knob 28 disposed at the bottom of the threaded rod 27.

[0044] When in use, the design of the knob 28 makes it easy to grip and rotate, controlling the rotation of the threaded rod 27. At the same time, the grooves on the surface of the knob 28 can increase friction when rotating, making it less likely to slip.

[0045] In some embodiments, the clamping assembly 2 further includes a ring 29 disposed at the bottom of the storage box 11.

[0046] When in use, the design of the ring 29 can support the bottom of the storage box 11, making it easy to place the storage box 11.

[0047] In some embodiments, a pressing assembly 3 is provided inside the cover 12, the pressing assembly 3 including: a spring 31 disposed on the inner side wall of the cover 12; and a pressure plate 32 disposed at the bottom end of the spring 31.

[0048] When in use, after the lid 12 is installed on the top of the storage box 11, the pressure plate 32 will fit against the top of the sample container. At the same time, the spring 31 will rebound and push the pressure plate 32 to make the sample container less likely to come out of the inside of the clamp 24, further stabilizing the position of the sample container.

[0049] In some embodiments, the clamping assembly 3 further includes: the bottom end of the upright 33 passes through the top of the cover 12 and passes through the spring 31 to connect with the pressure plate 32.

[0050] The design of the upright 33 during use prevents the spring 31 from bending when compressed, thus better protecting the spring 31 and stabilizing the movement trajectory of the pressure plate 32 to prevent deviation.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. In addition, those skilled in the art can combine and integrate the different embodiments or examples described in this specification.
