Description

Technical Field

[0001] The utility model relates to the technical field of geological exploration equipment, in particular to a portable shale exploration and sampling device. Background Art

[0002] Shale exploration sampling devices have important applications in oil and gas exploration and geological research. Shale is a sedimentary rock rich in organic matter that, through certain geological processes, can generate oil and natural gas. Therefore, shale exploration is crucial for assessing potential oil and gas resources. During the initial geological exploration phase, scientists and engineers use sampling devices to obtain samples of underground shale. These samples can be used to analyze the rock's physical and chemical properties, such as porosity, permeability, and organic carbon content. These data are crucial for evaluating the rock's oil and gas potential.

[0003] However, when using some existing shale exploration sampling devices, staff are usually required to determine the exploration sampling location, then move the sampling device to a suitable location, and finally start the drill bit to allow the device to sample it. However, this does not take into account the problem that the shale exploration sampling device is inconvenient to carry, so special transportation equipment and more manpower are required to move it, which directly increases transportation costs. In some remote or complex terrain areas, the transportation of large equipment is particularly difficult and expensive, and in areas with complex terrain or limited space, the operation of large equipment may be restricted, which limits the flexibility and accessibility of exploration. Therefore, a portable shale exploration sampling device is proposed to solve the above problems. Utility Model Content

Then, the insert plate 16 can be fixed by snapping with the snap plate 21.

[0035] Working Principle: Activate hydraulic rod 2. The output end of hydraulic rod 2 is fixedly connected to fixed sleeve 3. Activating hydraulic rod 2 drives fixed sleeve 3 up and down. Fixed sleeve 3 is externally connected to multiple fixed plates 1 (4). When fixed sleeve 3 moves, fixed plates 1 (4) also move with it. Fixed plates 1 (4) are externally connected to multiple connecting plates 5. Connecting plates 5 rotate to coordinate with fixed plates 2 (6) and 3 (8). As fixed plates 1 (4) move, connecting plates 5 drive fixed plates 3 (8) and support legs 9, thereby adjusting the overall stability and height of the device and ensuring it remains stable during exploration and sampling.

[0036] The hydraulic rod 2 also drives the up and down movement of the mounting plate 10, which is located at the bottom of the fixed sleeve 3 and in contact with it. When the mounting plate 10 moves, it drives the connecting components fixedly connected on both sides thereof to move synchronously. The connecting component is composed of four support columns 11, two support columns 11 are located on the left side of the mounting plate 10, and two support columns 11 are located on the right side. The support columns 11 connect the mounting plate 10 with the mounting plate 2 12, so the movement of the mounting plate 10 will also drive the mounting plate 2 12 to move. The function of the mounting plate 2 12 is to provide stable support for the drive assembly. A motor 13 is fixedly connected to the top of the mounting plate 2 12, and the motor 13 is the core power device of the drive assembly.

[0037] The output end of motor 13 is connected to an output shaft 14, which is further connected to the top of a sampling tube 15. When motor 13 is started, the rotation of output shaft 14 drives sampling tube 15, thereby starting shale sampling. Multiple insert plates 16 are connected to the bottom of sampling tube 15. These insert plates 16 work in conjunction with snap-fit ​​plates 21 within cavity 18, and are stabilized by dampers 19 and springs 20. During the sampling process, insert plates 16 ensure a tight connection between sampling tube 15 and the rest of the device.

[0038] When the depth of drill bit 17 needs to be adjusted, the height of fixed sleeve 3 and mounting plate can be adjusted by moving hydraulic rod 2, thereby adjusting the position of motor 13 and drill bit 17 to control the sampling depth. Drill bit 17 is located at the bottom of sampling tube 15, and its primary function is to drill and sample shale. Drill bit 17 is internally provided with multiple cavities 18. Dampers 19 within these cavities, working in conjunction with springs 20, provide stable support and cushioning during operation, ensuring smooth sampling within the rock formation without being affected by excessive impact forces.

[0039] During use, the spring 20 and damper 19 allow operators to easily install and remove the drill bit 17. If the drill bit 17 becomes damaged due to prolonged use, the operator can reverse the rotation of the sampling tube 15 to separate it from the locking plate 21. Once the sampling tube 15 is separated from the locking plate 21, the drill bit 17 can be easily removed and replaced, extending the service life of the device.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
