Description

Technical Field

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

[0002] Shale sampling devices are primarily used in the exploration and development of unconventional energy sources such as shale gas and shale oil. They are primarily used to obtain shale samples from underground rock formations for analysis. Geologists use methods such as seismic exploration to preliminarily determine the depth and extent of shale formations and determine their mining value. Engineering teams install shale sampling devices on drilling equipment. These devices typically include a coring drill bit, drill pipe, and sampling barrel, and are used to extract shale samples from the formation during the drilling process.

[0003] However, the existing methods usually directly move the sampling device for shale exploration and development to a suitable position, and then directly start the device, so that the device drives the drill pipe and drill bit to drill the shale to obtain the sample. However, it is not considered that when drilling the shale, the device will vibrate due to the contact of the drill bit with the shale, which will cause the device to shake. Since shale is usually structurally fragile, the shaking will increase the stress of the sample, making it easy to break, which will make it impossible to obtain a complete core and affect laboratory analysis. Therefore, a sampling device for shale exploration and development is proposed to solve the above problems. Utility Model Content

[0035] Working Principle: First, the drive assembly moves the base plate 1 to the predetermined sampling position. The drive assembly includes a hydraulic rod 2 and bottom movable wheels. The design of the movable wheels ensures greater stability during movement, and the provision of external anti-skid grooves effectively prevents the device from slipping on complex terrain. Once the device reaches the target position, the hydraulic rod 2 is activated. The output end of the hydraulic rod 2 drives the mounting plate 3 up and down, thereby connecting the mounting plate to the rotating plate 7 via the connecting plate 5, driving the rotating plate 7 to rotate.

[0036] Under the action of hydraulic rod 1 (2), rotating plate 7 gradually moves downward until its bottom support feet 9 contact the ground. This contact provides the device with additional support, preventing it from shaking during use and improving its stability. This step ensures that subsequent sampling work is carried out in a stable state.

[0037] After the device stabilizes, the adjustment assembly is activated to adjust the sampling depth. This assembly includes a hydraulic rod 12 mounted on the top inner wall of the containment shell 11. Driven by this, a sliding plate 13 slides up and down within the containment shell 11. A supporting plate 14 is attached to the outside of the sliding plate 13 and connected to it. When the sliding plate 13 moves, the supporting plate 14 also moves with it, thereby adjusting the sampling assembly.

[0038] The sliding plate 13 is guided by the sliding of the limit rod 20, making its movement more stable and ensuring the accurate position of the carrier plate 14. A sampling assembly is fixedly connected to the top left side of the carrier plate 14. The core of the sampling assembly is the motor 15. The motor 15 drives the rotation of the connecting tube 16 through its output end. The connecting tube 16 is equipped with a threaded groove 17 on its exterior. The user can add different sampling tubes 18 as needed to adjust the sampling depth.

[0039] When the sliding plate 13 moves to the appropriate position, the motor 15 is activated to rotate the connecting tube 16. The connecting tube 16 is connected to the sampling tube 18 via a threaded groove 17. The threaded design facilitates the installation and removal of the sampling tube 18. By adjusting the number of sampling tubes 18 installed, the shale mining depth can be flexibly controlled to meet sampling requirements at different depths.

[0040] After the sampling tube 18 is installed, the sampling head 19 is mounted at its base. As the motor 15 starts, the sampling head 19 begins to operate, penetrating deep into the shale layer. Through rotation and pressure, it collects shale samples into the sampling tube 18. During this process, the stability of the device is crucial. The support legs 9 ensure that the sampling accuracy is not affected by vibration or external interference.

[0041] Once the shale sample has been collected by the sampling tube 18, the motor 15 is stopped and the sampling tube 18 is removed from the connecting tube 16. The sample is sealed in the sampling tube 18, which is then removed from the device by rotating it. The sample is then transferred to a dedicated storage container and sent to a laboratory for analysis.

[0042] 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.
