Description

Technical Field

[0001] This utility model relates to the field of sampling equipment technology, specifically a sampler for marine oil exploration. Background Technology

[0002] When exploring offshore oil, it is often necessary to analyze the composition of the oil to determine whether further exploitation is needed. In the process of analyzing the composition of the oil, it is necessary to take samples of the oil extracted during exploration so that a portion can be taken back to the laboratory for analysis.

[0003] Currently, existing marine oil exploration samplers can only sample oil at a fixed depth, and a single sampling can only obtain an oil sample from one depth. If sampling at different depths is required, repeated sampling is necessary, resulting in low sampling efficiency. To address this, we propose a marine exploration sampler. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a sampler for marine oil exploration, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A sampler for marine oil exploration includes a sampling rod with several sample storage cavities inside. The sampling rod also has two rotating grooves inside. A rotating shaft is rotatably mounted in the center of the sampling rod. Both ends of the rotating shaft extend to the inner side of the rotating grooves and are fixedly mounted with turntables. A through hole is provided inside the turntable, which mates with the sample storage cavities. Several sample inlets are provided inside the bottom of the sampling rod, and several exhaust ports are provided inside the top of the sampling rod. The sample inlets and exhaust ports mate with the through holes and the sample storage cavities, respectively. A mounting groove is provided in the center of the sampling rod. A fixed angle plate is fixedly mounted outside the rotating shaft and inside the mounting groove. Several swivel grooves are provided inside the fixed angle plate. A servo motor is fixedly mounted at the bottom of the mounting groove. A disc is fixedly mounted at the output end of the servo motor. A lever is fixedly mounted on the top of the disc, and the lever mates with the swivel grooves.

[0006] Preferably, a guide plate is fixedly installed on the top of the disc, and a groove that mates with the guide plate is opened on the outer side of the fixed angle disc.

[0007] Preferably, a mounting rod is fixedly installed at the bottom of the sampling rod, and a drill bit is installed at the bottom of the mounting rod.

[0008] Preferably, a connecting rod is fixedly installed on the top of the sampling rod.

[0009] Preferably, the turntable is rotatably connected to the inner wall of the rotating groove.

[0010] Preferably, the sampling rod has a hole inside that mates with the rotating shaft.

[0011] This utility model provides a sampler for marine oil exploration, which has the following advantages:

[0012] This marine oil exploration sampler, with its configuration of a sample storage chamber, rotating groove, rotating shaft, turntable, through hole, sample inlet, exhaust port, mounting groove, fixed angle plate, dialing groove, servo motor, disc, and lever, allows for efficient sampling. During sampling, simply activating the servo motor drives the disc to rotate. The lever on the disc, in conjunction with the dialing groove, moves the fixed angle plate, causing the rotating shaft and turntable to rotate 60°. This allows the through holes inside the two turntables to simultaneously rotate to both ends of a single sample storage chamber. At this point, air inside the sample storage chamber is expelled through the exhaust port, while oil enters the sample storage chamber through the sample inlet, completing the sampling. After sampling, activating the servo motor again drives the turntable to rotate 60°, removing the through hole from one end of the sample storage chamber and sealing it. This process can be repeated at different depths to complete sampling at various depths. It is convenient, fast, and efficient, capable of detecting and sampling oil at different depths.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 6 This utility model provides a technical solution: a sampler for marine oil exploration, including a sampling rod 1, with several sample storage cavities 2 inside the sampling rod 1, two rotating grooves 3 inside the sampling rod 1, a rotating shaft 4 rotatably mounted in the middle of the sampling rod 1, and holes inside the sampling rod 1 that mate with the rotating shaft 4. Both ends of the rotating shaft 4 extend to the inner side of the rotating grooves 3 and are fixedly mounted with turntables 5, which are rotatably connected to the inner wall of the rotating grooves 3. Through holes 6 are provided inside the turntables 5, mate with the sample storage cavities 2. Several sample inlets 7 are provided inside the bottom of the sampling rod 1, and several exhaust ports 8 are provided inside the top of the sampling rod 1. The sample inlets 7 and exhaust ports 8 respectively mate with the through holes 6 and the sample storage cavities 2. An installation groove 9 is provided in the middle of the sampling rod 1, and the rotating shaft 4 passes through the installation groove 9. A fixed angle plate 10 is fixedly installed inside the mounting groove 9. The fixed angle plate 10 has several slots 11. A servo motor 12 is fixedly installed at the bottom of the mounting groove 9. A disc 13 is fixedly installed at the output end of the servo motor 12. A lever 14 is fixedly installed on the top of the disc 13. The lever 14 cooperates with the slots 11. A guide plate 15 is fixedly installed on the top of the disc 13. A groove that cooperates with the guide plate 15 is opened on the outer side of the fixed angle plate 10. The function of the guide plate 15 is to guide and limit the fixed angle plate 10. There are three sample storage chambers 2 inside the sampling rod 1, which can sample oil at three different depths. The spacing angle of each sample storage chamber 2 is 120°. Only after the servo motor 12 drives the rotating shaft 4 to rotate 120° can the through hole 6 on the turntable 5 be connected to the sample storage chamber 2 for sampling.

[0022] A mounting rod 16 is fixedly installed at the bottom of the sampling rod 1, a drill bit 17 is installed at the bottom of the mounting rod 16, and a connecting rod 18 is fixedly installed at the top of the sampling rod 1.

[0023] In summary, this marine oil exploration sampler, when in use, only requires turning on the servo motor 12 to drive the disc 13 to rotate. The lever 14 on the disc 13 cooperates with the slot 11 to move the fixed angle disc 10, causing the rotating shaft 4 and the disc 5 to rotate 60°. This allows the through holes 6 inside the two discs 5 to rotate simultaneously to both ends of a sample storage chamber 2. At that time, the air in the sample storage chamber 2 is discharged from the exhaust port 8, and the oil enters the sample storage chamber 2 through the inlet 7, thus completing the sampling. After sampling, the servo motor 12 is turned on again to drive the disc 5 to rotate 60°, so that the through holes 6 are removed from one end of the sample storage chamber 2, sealing the sample storage chamber 2. Subsequently, sampling can be carried out sequentially at different depths to complete sampling at different depths. It is convenient and quick to use, and can detect and sample oil at different depths with high sampling efficiency.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
