Description

Technical Field

[0001] This utility model belongs to the technical field of petroleum sampling devices, and in particular relates to a petroleum measuring sampler. Background Technology

[0002] Petroleum, a primary target of geological exploration, is a dark brown liquid often referred to as "the blood of industry." Petroleum reserves are found in certain areas of the Earth's upper crust. Its main components are a mixture of various alkanes, cycloalkanes, and aromatic hydrocarbons.

[0003] In the process of oil sampling, the traditional sampling method is usually single-point sampling. Workers lower the sampling tank, the sample enters the container, and then it is pulled up and poured into the container. When multiple sampling points are required, workers need to pull up and down back and forth to sample the oil. The whole process is very troublesome and cumbersome. To address this, we have provided an oil measurement sampler. Utility Model Content

[0004] The purpose of this invention is to provide an oil measurement sampler that solves the problems described in the background section.

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 - Figure 4 This utility model relates to an oil measurement sampler, comprising a support base 1 and a support frame 2 fixed to the upper surface of the support base 1; a threaded rod 8 and a guide rod 13 are symmetrically arranged between the lower surface of the support frame 2 and the upper surface of the support base 1, respectively. A slider 3 is slidably arranged on the outer wall of both the threaded rod 8 and the guide rod 13. The support frame 2 and the support base 1 are rotatably connected to the threaded rod 8, and the support frame 2 and the support base 1 are fixedly connected to the guide rod 13. The threaded rod 8 and the slider 3 are threadedly connected. A worm gear 7 is fixedly connected to the outer wall of the threaded rod 8. Two fixing plates 6 are symmetrically fixed to the lower surface of the support frame 2, and a worm 21 that meshes with the worm gear 7 is rotatably arranged between the two fixing plates 6. The outer wall of one of the fixing plates 6 rotates. A throttle 23 is connected to one end of a worm gear 21. A piston cylinder 5 is connected to the lower surface of the support base 1. A piston rod 4, which slides inside the piston cylinder 5, is fixedly connected to the lower surface of the slider 3. A liquid extraction hose 9 is connected to the end of the piston cylinder 5. A one-way valve 24 is connected to the outer wall of the liquid extraction hose 9. A connecting hose 14 is connected to the outer wall of the piston cylinder 5. A puncture head 16 is connected to one end of the connecting hose 14. A sample storage assembly is fixedly installed on the inner side of the support base 1. The sample storage assembly includes a support block 17. A sample storage bottle 18 is movably connected to the upper surface of the support block 17. A rubber cap 15 is threadedly connected to the upper surface of the sample storage bottle 18. An outlet pipe 19 is connected to the upper surface of the rubber cap 15. A control valve 20 is connected to the outer wall of the outlet pipe 19.

[0023] After securing the support base 1 with bolts, insert the suction hose 9 into the oil tank where sampling is required. Pierce the rubber cap 15 with the puncture head 16, connecting it to the sample storage bottle 18. Rotate the handle 23 to drive the worm gear 21, which in turn drives the worm wheel 7. The rotation of the worm wheel 7 causes the threaded rod 8 to rotate, which in turn causes the slider 3 to move linearly upwards along the outer wall of the threaded rod 8. During this upward movement, the slider 3 also causes the piston rod 4, which slides inside the piston cylinder 5, to rise. A low-pressure zone is created inside the piston cylinder 5, drawing the oil sample from the tank. Under the pressure difference, the oil sample preferentially enters the piston cylinder 5, preventing it from entering the sample storage bottle 18. When an oil sample is injected, the handle 23 is rotated in the opposite direction, which, in conjunction with the worm gear 7 and worm 21, drives the threaded rod 8 to reverse. At this time, the slider 3 descends. Under the action of the one-way valve 24, the liquid cannot flow out through the suction hose 9. The oil sample in the piston cylinder 5 enters the sample storage bottle 18 through the connecting hose 14 and the puncture head 16. The control valve 20 on the rubber cap 15 is opened so that the air in the sample storage bottle 18 can be discharged through the liquid outlet pipe 19, reducing the pressure in the sample storage bottle 18. After the oil sample is injected, the puncture head 16 on the rubber cap 15 is pulled out, the sample storage bottle 18 is taken out, a new sample storage assembly is connected, and the above steps are repeated to achieve multi-point extraction of oil samples.

[0024] Please see Figure 1 The outer wall of the bearing block 17 is fixedly connected to an elongated plate 11 through which the liquid extraction hose 9 passes, and the outer wall of the liquid extraction hose 9 is slidably connected to a limiting ring 22 that cooperates with the elongated plate 11.

[0025] The length of the suction hose 9 is matched according to the actual use. When taking oil samples, when the length of the suction hose 9 is lowered to the appropriate position, the limiting ring 22 on the suction hose 9 is moved to contact the upper surface of the elongated plate 11. There is a certain friction between the limiting ring 22 and the suction hose 9, which limits the suction hose 9 so that the suction hose 9 can be lowered to the accurate position.

[0026] Please see Figure 1 A counterweight 10 is fixedly connected to the outer wall of the liquid extraction hose 9, and scale lines 12 are opened on the outer wall of the liquid extraction hose 9.

[0027] By installing a counterweight 10 on the outer wall of the suction hose 9, the suction hose 9 can be kept in a relatively straight position when extracting oil samples, making the oil extraction process smoother. The scale line 12 on the outer wall of the suction hose 9 can accurately determine the lowering position and distance.

[0028] The operation process of this embodiment is as follows: The support base 1 is fixed with bolts. After fixing, the suction hose 9 is placed into the oil tank to be sampled. The piercing head 16 pierces the rubber cap 15, connecting it to the sample storage bottle 18. The handle 23 is rotated to drive the worm gear 21 to rotate the worm wheel 7. The rotation of the worm wheel 7 drives the threaded rod 8 to rotate as well. The rotation of the threaded rod 8 causes the slider 3 to move linearly upwards along the outer wall of the threaded rod 8. During the upward movement of the slider 3, the piston rod 4 sliding inside the piston cylinder 5 also rises. A low-pressure zone is formed inside the piston cylinder 5 to extract the oil sample from the tank. At this time, under the action of the pressure difference, the oil sample preferentially enters the interior of the piston cylinder 5, and the sample storage bottle 1... Oil sample will not enter the interior of sample 8. Reverse rotation of handle 23, in conjunction with worm gear 7 and worm 21, drives threaded rod 8 to reverse. At this time, slider 3 descends. Under the action of one-way valve 24, liquid cannot flow out through the suction hose 9. Oil sample in piston cylinder 5 enters the sample storage bottle 18 through connecting hose 14 and puncture head 16. Open control valve 20 on rubber cap 15 to allow air in sample storage bottle 18 to be discharged through outlet pipe 19, reducing the pressure in sample storage bottle 18. After the oil sample is injected, pull out puncture head 16 on rubber cap 15, remove sample storage bottle 18, connect a new sample storage assembly, and repeat the above steps to achieve multi-point extraction of oil sample.
