Description

Technical Field

[0001] This utility model relates to the field of geological exploration technology, and in particular to a corrosion-resistant petroleum sediment geological sample collector. Background Technology

[0002] In the process of oil exploration and development, the accurate collection of sedimentary geological samples is crucial for understanding the structure of underground rock strata, mineral composition and oil content, and requires the use of oil sedimentary geological sample collectors.

[0003] Existing petroleum sedimentary geological sampling equipment typically involves drilling a sampling tube into the soil for sampling. However, because the sampling tube is in direct contact with the soil, it is prone to corrosion when sampling in geological environments with high acidity or salinity, leading to shortened equipment lifespan, sample contamination, and decreased sampling accuracy.

[0004] Therefore, a corrosion-resistant petroleum sedimentary geological sampler has now been developed that can prevent the extension tube and placement tube from being corroded, thereby improving the service life of the equipment and the sampling accuracy. Utility Model Content

[0005] To overcome the shortcomings of existing petroleum sedimentary geological sample collectors, which are prone to corrosion of the sampling tube when sampling in geological environments with high acidity or salinity, resulting in shortened equipment life, sample contamination, and reduced sampling accuracy, this utility model provides a corrosion-resistant petroleum sedimentary geological sample collector that can prevent corrosion of the extension tube and placement tube, thereby improving equipment life and sampling accuracy.

[0006] The technical solution is as follows: A corrosion-resistant petroleum sediment geological sample collector includes a tracked vehicle, a hydraulic press, a pressure head, a rotating block, a first motor, a gear set, a sampling component, and a docking component. The hydraulic press is connected to the front of the tracked vehicle. The pressure head is connected to the telescopic end of the hydraulic press. The rotating block is rotatably connected to the pressure head. The first motor is connected to the front of the telescopic end of the hydraulic press. A gear set is connected between the output shaft of the first motor and the rotating block. The pressure head is equipped with a sampling component capable of sampling. The sampling component is equipped with a docking component capable of docking.

[0007] As an improvement to the above solution, the sampling assembly includes a placement tube, a second motor, a drill bit, an electric actuator, a connecting plate, a sampling tube, a rotating tube, and an extension tube. An extension tube is provided under the pressure head, and the placement tube is threadedly connected to the lower side of the extension tube. The second motor is connected to the lower inner side of the placement tube, and the drill bit is connected to the output shaft of the second motor. The drill bit is rotatably connected to the placement tube. Two electric actuators are connected inside the placement tube and the extension tube. A connecting plate is connected between the telescopic ends of two adjacent electric actuators. Multiple sampling tubes are threadedly connected to the connecting plate. Rotating tubes are rotatably connected to the placement tube and the extension tube. The upper rotating tube is engaged with the rotating block.

[0008] As an improvement to the above scheme, multiple sampling holes are opened on both the placement tube and the extension tube.

[0009] As an improvement to the above scheme, the front side of the sampling tube is all inclined.

[0010] As an improvement to the above solution, the rotating tubes are all made of corrosion-resistant materials.

[0011] As an improvement to the above solution, the docking assembly includes a connecting frame and a telescopic spring. Multiple connecting frames are slidably connected inside the upper rotating tube, and each connecting frame is connected to the upper rotating tube by a telescopic spring.

[0012] The beneficial effects are as follows: By starting the first motor, the gear set meshes and drives the rotating block to rotate, so that the rotating tube rotates and connects with the sampling holes on the placement tube and the extension tube. Then, the electric push rod is started to push the connecting plate to move outward, so that the sampling tube moves outward and is inserted into the soil for sampling. This achieves the effect of preventing the extension tube and the placement tube from being corroded, improving the service life of the equipment and the sampling accuracy.

[0020] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0021] A corrosion-resistant petroleum sedimentary geological sample collection device, such as Figures 1-6 As shown, the system includes a tracked vehicle 1, a hydraulic press 2, a pressure head 3, a rotating block 4, a first motor 5, a gear set 6, a sampling component, and a docking component. The hydraulic press 2 is connected to the front of the tracked vehicle 1. The pressure head 3 is connected to the telescopic end of the hydraulic press 2. The rotating block 4 is rotatably connected to the pressure head 3. The first motor 5 is connected to the front of the telescopic end of the hydraulic press 2. The gear set 6 is connected between the output shaft of the first motor 5 and the rotating block 4. The pressure head 3 is equipped with a sampling component, and the sampling component is equipped with a docking component.

[0022] like Figures 3-6 As shown, the sampling assembly includes a placement tube 7, a second motor 8, a drill bit 9, an electric actuator 10, a connecting plate 11, a sampling tube 12, a rotating tube 13, and an extension tube 14. The extension tube 14 is located below the pressure head 3, and the placement tube 7 is threadedly connected to the lower side of the extension tube 14. Both the placement tube 7 and the extension tube 14 have three sampling holes for easy sampling. The second motor 8 is connected to the lower inner side of the placement tube 7, and the drill bit 9 is connected to the output shaft of the second motor 8. The drill bit 9 is rotatably connected to the placement tube 7. Both the placement tube 7 and the extension tube 14 are internally connected to two electric push rods 10, one above the other. The telescopic ends of two adjacent electric push rods 10 are connected to a connecting plate 11. Three sampling tubes 12 are threaded onto the connecting plate 11. The front side of each sampling tube 12 is beveled for easy sampling. Both the placement tube 7 and the extension tube 14 are rotatably connected to a rotating tube 13. The rotating tubes 13 are made of corrosion-resistant material to adapt to different environments. The upper rotating tube 13 is engaged with the rotating block 4.

[0023] like Figure 6 As shown, the docking assembly includes a connecting frame 15 and a telescopic spring 16. Two connecting frames 15 are slidably connected inside the upper rotating tube 13, and each connecting frame 15 is connected to the telescopic spring 16 between itself and the upper rotating tube 13.

[0024] When using this utility model, firstly, the tracked vehicle 1 is started and moved to the oil sediment geological sample collection area. After reaching the designated position, according to the sampling requirements, the corresponding number of extension tubes 14 are spliced ​​together, and then the placement tube 7 is placed at the drilling position. Subsequently, the hydraulic press 2 is started, causing the pressure head 3 to move downward and contact the extension tube 14. At the same time, the second motor 8 is started, driving the drill bit 9 to rotate, pushing the extension tube 14 and the placement tube 7 downward to drill into the soil. When the pressure head 3 moves downward and contacts the extension tube 14, the upper rotating tube 13 engages with the rotating block 4. At this time, the rotating block 4 presses the connecting frame 15 downward to engage with the lower rotating tube 13. The telescopic spring 16 is stretched, connecting the rotating tube 13. After the extension tube 14 and the placement tube 7 have drilled into the soil to the designated depth, the first motor 5 is started. The gear set 6 meshes, driving the rotating block 4 to rotate, causing the rotating tube 13 to rotate and connect with the sampling holes on the placement tube 7 and the extension tube 14. Then, the electric push rod 10 is activated, pushing the connecting plate 11 to move outward, causing the sampling tube 12 to move outward and insert into the soil for sampling. This prevents the extension tube 14 and the placement tube 7 from being corroded, improving the service life of the equipment and the sampling accuracy. After sampling, the rotating tube 13 is reset to close the sampling holes on the placement tube 7 and the extension tube 14. Then, the placement tube 7 and the extension tube 14 are moved upward to detach from the soil. The sampling tube 12 can then be pushed out and removed from the connecting plate 11. The sample inside the sampling tube 12 is collected. After the rotating block 4 disengages from the connecting frame 15, it rebounds through the telescopic spring 16, causing the connecting frame 15 to reset.

[0025] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the present invention and should not be construed as limiting the scope of protection of the present invention in any way. Based on this explanation, those skilled in the art can conceive of other specific embodiments of the present invention without creative effort, and these embodiments will all fall within the scope of protection of the present invention.
