Description

Technical Field

[0001] This utility model relates to the field of oilfield sampling technology, specifically to a crude oil sampling device for an unloading platform. Background Technology

[0002] Oil unloading platforms (oil pull-out ports) are one of the important interfaces for crude oil production transfer in various oil production plants of oil fields. Currently, the production is generally calculated by manually sampling and testing.

[0003] The position of the sampling chamber or sampling tube is difficult to adjust freely, and the sampling chamber or sampling tube is difficult to limit and fix, which makes the sampling process inconvenient. At the same time, the sample oil is easy to come into contact with the outside and cause contamination, resulting in inaccurate test results. Multiple tests are required, which increases costs and workload.

[0004] Announcement No. CN217520816U discloses an automatic sampling device for oil product testing, including a base plate and a fixed plate. The fixed plate is fixedly connected to the surface of the base plate, and a lifting platform is slidably connected to the surface of the fixed plate. An installation assembly is provided on the surface of the lifting platform, and a liquid storage cylinder is provided inside the installation assembly. A sampling tube is connected to the bottom of the liquid storage cylinder. A lifting mechanism is provided inside the fixed plate. The lifting mechanism includes a rotating rod, a motor, a lifting frame, and a guide rod. The lifting frame is slidably connected to the inside of the fixed plate. An installation plate is fixedly connected to the surface of the fixed plate, and the motor is fixedly installed on the surface of the installation plate. The rotating rod is fixedly connected to the output end of the motor.

[0005] The existing technology performs automatic testing after sampling, but the data accuracy is limited. When precise data is required for laboratory testing, the liquid storage cylinder of the existing technology is always located above the sampling port, making it difficult to transfer the sample liquid in the liquid storage cylinder to the oil sample container.

[0006] Announcement No. CN219200969U discloses a crude oil testing and sampling device, including a workbench. A mounting frame is fixedly installed on the top of the workbench. A mounting box is fixedly installed on the top of the mounting frame. A first motor is fixedly installed inside the mounting box. A placement box is fixedly installed at the bottom of the mounting box. The output end of the first motor extends into the interior of the placement box and is fixedly installed with a threaded rod. A sampling cylinder is fixedly installed at the bottom of the placement box. A threaded sleeve is threadedly connected to the surface of the threaded rod. Sliding rods are fixedly installed on both sides of the top of the placement box. Sliding sleeves are fitted onto the surfaces of the two sliding rods.

[0007] The existing technology requires the entire device to be moved using pulleys before the oil receiving hopper can be rotated out, making the operation cumbersome.

[0008] Publication No. CN119510060A discloses a sampler for sampling oil in an oil injector, including a bracket and a servo motor fixedly installed on the left side of the bracket. A threaded rod is fixedly installed at the output end of the servo motor, and a movable block is threaded on the surface of the threaded rod. An electric telescopic rod is installed through the front end of the movable block, and a sampling suction head is fixedly installed at the lower output end of the electric telescopic rod.

[0009] In this existing technology, the oil sample inside the bellows is not easily emptied, which can contaminate the oil sample taken a second time.

[0010] In summary, the technical solutions, technical problems to be solved, and beneficial effects of the above-disclosed technologies are all different from those of this utility model. For more technical features, technical problems to be solved, and beneficial effects of this utility model, the above-disclosed technical documents do not provide any technical inspiration.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1:

[0033] Please see Figures 1 to 4 The present invention provides a crude oil sampling device for an unloading platform, comprising a guide limiting component, a movable connecting component, and a sampling component. One end of the movable connecting component is rotatably and slidably connected to the guide limiting component, and the end of the movable connecting component away from the guide limiting component is fixedly connected to the sampling component.

[0034] Furthermore, the guide limiting assembly includes a support column 2, a lower limiting plate 3, and an upper limiting plate 4. The support column 2 is cylindrical, and the outer wall of the support column 2 is threadedly connected to the lower limiting plate 3 and the upper limiting plate 4. The movable connection assembly includes at least two movable connection units, each of which includes a connecting arm 6. The two ends of the connecting arm 6 are respectively provided with a movable ring 5 and a connecting clamp 7. The movable ring 5 is slidably and rotatably sleeved on the outer wall of the support column 2. The movable ring 5 is located between the lower limiting plate 3 and the upper limiting plate 4. The connecting clamp 7 is connected to the sampling assembly.

[0035] Specifically, a mounting base 1 is provided at the lower end of the support column 2 for the installation of the device.

[0036] Specifically, the connecting arms 6 of the at least two movable connecting units are connected by a connecting rod, and one end of the connecting rod extends out of the connecting arm 6 and is connected to the first handle 11; in use, people can control the movable connecting components to swing left and right or move up and down by pulling the first handle 11.

[0037] Furthermore, the sampling assembly includes a sampling chamber 8, which is threadedly fixed inside the connecting clamp 7. A sampling tube 9 is located at the lower end of the sampling chamber 8. A piston block 14 is slidably installed inside the sampling chamber 8, and a piston rod 13 is fixed to the piston block 14. The upper end of the piston rod 13 extends vertically upward through the top surface of the sampling chamber 8, and the upper end of the piston rod 13 is fixedly connected to the second handle 12. During sampling, the sampling tube 9 is placed in the sampling oil, and then the second handle 12 is pulled upward, causing the piston block 14 to move like a piston within the sampling chamber 8, thereby extracting the sample oil and discharging it outward through the sampling tube 9, facilitating quick and easy removal of the sample oil. In addition, the height and lateral position of the sampling chamber 8 can be adjusted by pulling the first handle 11, preventing the sample oil from contacting the outside and causing contamination, thus improving the detection accuracy of the sample oil.

[0038] Specifically, a return spring 17 and an internal baffle 15 are sleeved on the outer wall of the piston rod 13 inside the sampling chamber 8. The lower end of the return spring 17 is connected to the piston rod 13, and the internal baffle 15 is located at the upper end of the return spring 17. The internal baffle 15 is connected to the sampling chamber 8 through a fixing rod 16. During the sampling process, people pull the second handle 12 upward to make the piston block 14 slide upward in the sampling chamber 8, thereby extracting sample oil. At this time, the return spring 17 is compressed by pressure. When the second handle 12 is released, the elastic force of the return spring 17 will drive the piston block 14 to return to its original position, which makes it convenient for people to use the sampling chamber 8 repeatedly for sampling. During the process of the piston block 14 returning to its original position, the sample oil in the sampling chamber 8 will be discharged out through the sampling tube 9, which makes it convenient for people to collect sample oil for testing.

[0039] Specifically, the piston rod 13 is provided with a spring seat connected to the return spring 17, or the lower end of the return spring 17 is welded to the piston rod 13.

[0040] Specifically, the lower limit plate 3 is provided with a lower limit mechanism, which includes a lower connecting block 301 and a lower hook 302. The lower connecting block 301 is fixedly installed on the outer side of the lower limit plate 3, and the lower hook 302 is fixedly installed on the top surface of the lower connecting block 301. The lower hook 302 is an "L"-shaped hook, and the horizontal part of the lower hook 302 is close to the movable connecting component. When using the sampling chamber 8 for sampling, since the movable sampling chamber 8 is difficult to fix, the sampling chamber 8 can be moved downwards, and the lowermost connecting arm 6 can be hooked into the lower hook 302. Through the cooperation of the connecting arm 6 and the lower hook 302, the sampling chamber 8 can be relatively fixed, thereby facilitating people to use the sampling chamber 8 for sampling operations.

[0041] Specifically, the upper limit plate 4 is equipped with an upper limit mechanism, which includes an upper connecting block 401 and an upper hook 402. The upper connecting block 401 is fixedly installed on the outer side of the upper limit plate 4, and the upper hook 402 is fixedly installed on the bottom surface of the upper connecting block 401. The upper hook 402 is an "L"-shaped hook, and the horizontal part of the upper hook 402 is close to the movable connecting component. When the sampling chamber 8 is not in use, people can pull the first handle 11 upward to make multiple sets of movable rings 5 ​​slide upward along the support column 2, thereby moving the sampling chamber 8 upward as a whole. At this time, by controlling the uppermost connecting arm 6 to hook into the upper hook 402, the upper hook 402 can play a role in suspending and limiting the connecting arm 6, keeping the sampling chamber 8 in a fixed position above the oil tank for easy use. When using the sampling chamber 8, simply control the connecting arm 6 to detach from the upper hook 402 to freely adjust the height of the sampling chamber 8.

[0042] Example 2:

[0043] Based on Example 1, this example provides an operation method for a crude oil sampling device at an unloading platform:

[0044] During operation, the user can effectively control the sampling chamber 8 to swing left and right or move up and down by pulling the first handle 11, so as to accurately place the sampling tube 9 into the oil to be sampled. Then, the user pulls the second handle 12 upwards. This action will drive the piston rod 13 and piston block 14 to perform piston movement inside the sampling chamber 8 to extract the oil sample. By adjusting the vertical position of the first handle 11, the user can flexibly adjust the height of the sampling chamber 8; while swinging the first handle 11 left and right can easily change the horizontal position of the sampling chamber 8, moving the sampling chamber 8 above the oil sample container, and smoothly discharge the extracted oil sample through the sampling tube 9. The oil sample has a high degree of emptying, avoiding residual contamination for the next sampling. This device greatly facilitates the oil sample collection process. The ingenious design of the sampling chamber 8 not only ensures rapid oil sample extraction, but also effectively avoids direct contact between the oil sample and the external environment, thereby improving the accuracy of oil sample testing.

[0045] When the sampling chamber 8 is not in use, the user can lift the first handle 11 to drive multiple sets of movable rings 5 ​​to slide smoothly upward along the support column 2, thereby raising the sampling chamber 8 as a whole. At this time, the user can precisely control the uppermost connecting arm 6 to embed it into the upper hook 402. Using the suspension limiting function of the upper hook 402, the sampling chamber 8 is securely suspended above the oil tank for subsequent use.

[0046] When oil sampling is required, if the movable sampling chamber 8 is difficult to stabilize, the user can lower the sampling chamber 8 so that the bottom connecting arm 6 is hooked into the lower hook 302. Through the close cooperation between the connecting arm 6 and the lower hook 302, the sampling chamber 8 can maintain a relatively fixed state, thus providing a more convenient and stable sampling operation environment for on-site operators.
