Description

Technical Field

[0001] This utility model relates to the field of bottled oil sampling technology, and in particular to a sampling device suitable for high pour point bottled oil. Background Technology

[0002] In the fields of petrochemicals and energy reserves, accurate sampling and analysis of high-pour-point bottled oil is a key step in assessing oil quality and monitoring storage conditions. High-pour-point oils have the characteristics of high viscosity and easy solidification at low temperatures, making it difficult to obtain samples smoothly using conventional bottled oil sampling devices.

[0003] Traditional sampling tools, especially in winter, are hampered by the solidified oil layer when dealing with high-pour-point oils. Furthermore, common sampling devices cannot achieve stratified sampling of oil samples at different depths within drums, often collecting all the oil into a single cavity. This sampling method results in overly simplistic test data that fails to comprehensively reflect the true mass distribution of the oil within the drum, and cannot provide accurate and valuable data support for production and storage. Therefore, this application proposes a sampling device suitable for high-pour-point drummed oils. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a sampling device suitable for high pour point bottled oil, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a sampling device suitable for high pour point bottled oil, including a sampling cylinder, a storage groove with an inner arc surface on the side of the sampling cylinder, a motor installed at the top of the sampling cylinder, a rotating rod connected to the output end of the motor that passes through the storage groove and extends to the bottom of the sampling cylinder, and a drill bit installed at the bottom end of the rotating rod, a linkage component provided on the left side of the sampling cylinder, multiple sampling tubes being fitted and installed in the storage groove, an oil inlet pipe communicating with the inside of each sampling tube being installed at the top of each sampling tube, a connecting component connected to the linkage component being installed at each oil inlet pipe, a handle being installed at the top right side of the sampling tube, and a battery holder being installed at the bottom of the handle.

[0006] Optionally, several limiting grooves are equidistantly provided on both sides of the inner wall of the storage slot. A slot is provided at the bottom of the inner end of each limiting groove. Limiting blocks adapted to the size of the limiting groove are installed on both sides of the sampling tube. A groove is provided at the bottom of each limiting block, and a locking block is movably inserted into each groove. A second spring is fixedly connected between the locking block and the inner end of the groove, and the part of the locking block extending out of the groove can be engaged in the corresponding slot.

[0007] Optionally, a U-shaped recessed area is provided on the side of the sampling tube, and a handle is installed on the top of the sampling tube on the side away from the recessed area. The center of the rotating rod is located on the same vertical axis as the center of the sampling cylinder, the storage groove, and the sampling tube, and the inner wall of the recessed area does not contact the rotating rod.

[0008] Optionally, the linkage assembly includes a first fixing block, a second fixing block, a vertical rod, a connecting rod, and a flipping ring. The first fixing block is fixedly installed at the lower left side of the sampling cylinder, and the second fixing block is fixedly installed at the upper left side of the sampling cylinder. Both the first and second fixing blocks have openings, and the vertical rod is inserted through the two openings. An anti-detachment plate is installed at the bottom of the vertical rod. A first spring sleeved on the vertical rod is connected to the bottom of the first fixing block at the top of the anti-detachment plate. A slot is opened at the bottom of the connecting rod, and the slot at the bottom of the connecting rod is hinged to the top of the vertical rod. Fixed shafts are fixedly installed on both the front and rear sides of the top of the side wall of the sampling cylinder. The flipping ring is sleeved on the top of the sampling cylinder, and both ends of the flipping ring are rotatably sleeved on the two fixed shafts. A fixing component is installed at the bottom left side of the flipping ring, and the top of the connecting rod is hinged to the fixing component. A pressure plate is installed on the right side of the flipping ring, and the pressure plate is located above the handle.

[0009] Optionally, the connecting assembly includes a connecting plate, a plugging tube, and an arc-shaped rod. The plugging tube is movably inserted into the oil inlet pipe. The connecting plate is installed at the top of the plugging tube. The arc-shaped rod is connected to the end of the connecting plate away from the plugging tube and is wound around the outside of the sampling tube. A notch is provided at the end of the arc-shaped rod away from the connecting plate and is sleeved on the outside of the vertical rod. A nut is threaded onto the notched end of the arc-shaped rod. A third spring sleeved on the outside of the oil inlet pipe is fixedly connected between the bottom of the connecting plate and the top of the sampling tube. An oil inlet is provided at the top of the side wall of the oil inlet pipe.

[0010] Optionally, the oil inlet pipe is installed at a position off-center from the top of the sampling pipe, and the outer wall of the sealing pipe is in contact with the inner wall of the oil inlet pipe.

[0011] The beneficial effects of this utility model are:

[0012] Multiple sampling tubes, fitted into the side storage slot of the sampling cylinder, allow for stratified sampling of oil at different depths within the drum. A connecting component inserted into the oil inlet pipe at the top of the sampling tube connects to a vertical rod in the linkage assembly. Pressing the pressure plate causes the left end of the flipping ring to tilt upwards, moving the connecting rod upwards. This causes the bottom end of the connecting rod to pull the vertical rod upwards between the first and second fixed blocks. As the vertical rod moves upwards, it moves the multiple connecting components connected to it upwards as well, causing the sealing tube in the connecting component to move upwards within the oil inlet pipe, exposing the oil inlet on the side wall of the oil inlet pipe. At this point, oil at different depths within the drum converges into the sampling tube through the oil inlet and the oil inlet pipe, thus achieving oil sampling. Compared to common sampling devices, this sampling method can collect oil at different depths and classify and store it, and it is less prone to oil spillage.

[0013] The battery holder provides power to the motor. Starting the motor and rotating the rod will drive the drill bit at the bottom of the sampling cylinder to rotate. The rotation of the drill bit can effectively break the solidified layer of high pour point oil, overcoming the problem that traditional devices cannot break through the solidified oil layer and ensuring that the sampling is carried out smoothly.

[0014] The end of the arc rod can be locked to the vertical rod by the threaded connection of the nut and the arc rod. When the vertical rod moves up, it can drive the connecting component to move up together. When removing the sampling tube, the nut can be unscrewed to take the sampling tube out of the storage slot. Then, the connecting component can be manually lifted to expose the oil inlet on the side wall of the sealing tube, and the oil collected in the sampling tube can be poured out.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] Please see Figures 1-9 This utility model provides a technical solution: a sampling device suitable for high pour point bottled oil, including a sampling cylinder 1. The sampling cylinder 1 has a storage groove 11 with an inner arc surface on its side. A motor 21 is installed at the top of the sampling cylinder 1. The output end of the motor 21 is connected to a rotating rod 22 that passes through the storage groove 11 and extends to the bottom of the sampling cylinder 1. A drill bit 23 is installed at the bottom end of the rotating rod 22. A linkage assembly 3 is provided on the left side of the sampling cylinder 1. Multiple sampling tubes 41 are fitted inside the storage groove 11. Each sampling tube... Each of the sampling tubes 41 is equipped with an oil inlet pipe 44 that communicates with its interior. Each oil inlet pipe 44 is equipped with a connecting component 5 that connects to the linkage component 3. A handle 12 is installed on the top right side of the sampling tube 41. A battery holder 13 is installed at the bottom of the handle 12. The battery holder 13 is electrically connected to the motor 21. The battery holder 13 can provide power for the operation of the motor 21, so that the motor 21 drives the drill bit 23 to break the solidified oil layer through the rotating rod 22, thus facilitating the sampling and testing of bottled oil in winter.

[0028] like Figure 1 , Figure 4 and Figure 9As shown, several limiting grooves 14 are equidistantly provided on both sides of the inner wall of the storage tank 11. A slot 15 is provided at the bottom of the inner end of each limiting groove 14. Limiting blocks 42 that are adapted to the size of the limiting grooves 14 are installed on both sides of the sampling tube 41. A groove is provided at the bottom of each limiting block 42, and a locking block 421 is movably inserted into each groove. A second spring 422 is fixedly connected between the locking block 421 and the inner end of the groove. The part of the locking block 421 that extends out of the groove can be locked into the corresponding slot 15. The sampling tube 41 is locked into the slot 15 at the bottom of the limiting groove 14 by the locking block 421 at the bottom of the limiting block 42, which can constrain the position of the sampling tube 41. By locking the limiting block 42 into the limiting grooves 14 at different heights, the position height of the sampling tube 41 in the storage tank 11 can be freely adjusted, so that the sampling depth of the barrelled oil can be adjusted according to the situation.

[0029] like Figure 1 , Figure 2 and Figure 7 As shown, a U-shaped recessed area 45 is provided on the side of the sampling tube 41, and a handle 43 is installed on the top of the sampling tube 41 on the side away from the recessed area 45. The center of the rotating rod 22 is located on the same vertical axis as the center of the sampling cylinder 1, the storage groove 11, and the sampling tube 41. The inner wall of the recessed area 45 does not contact the rotating rod 22. When the sampling tube 41 is installed in the storage groove 11, the rotating rod 22 is located in the recessed area 45, so that the rotating rod 22 can rotate normally without affecting the installation of the sampling tube 41.

[0030] like Figures 1 to 5As shown, the linkage assembly 3 includes a first fixing block 31, a second fixing block 32, a vertical rod 33, a connecting rod 36, and a flipping ring 37. The first fixing block 31 is fixedly installed at a lower position on the left side of the sampling cylinder 1, and the second fixing block 32 is fixedly installed at a higher position on the left side of the sampling cylinder 1. Both the first fixing block 31 and the second fixing block 32 have openings, and the vertical rod 33 is inserted through both openings. An anti-detachment plate 34 is installed at the bottom end of the vertical rod 33. A first spring 35, sleeved on the vertical rod 33, is connected to the top of the anti-detachment plate 34 and the bottom end of the first fixing block 31. A groove is opened at the bottom end of the connecting rod 36, and the groove at the bottom end of the connecting rod 36 is hinged to the top end of the vertical rod 33. Fixed shafts are fixedly installed on both the front and rear sides of the top of the side wall. The flip ring 37 is sleeved on the top of the sampling tube 1, and the two ends of the flip ring 37 are respectively rotatably sleeved on the two fixed shafts. A fixing part 38 is installed on the bottom left side of the flip ring 37. The top of the connecting rod 36 is hinged to the fixing part 38. A pressure plate 39 is installed on the right side of the flip ring 37, and the pressure plate 39 is located above the handle 12. By pressing the pressure plate 39 in the linkage assembly 3, the top connecting assembly 5 of multiple sampling tubes 41 can be moved upward at the same time, thereby opening the oil inlet pipe 44 at the top of the sampling tube 41 simultaneously. In this way, barrelled oil of different depths can converge into multiple sampling tubes 41 at the same time, thereby realizing the sampling of oil products of different depths.

[0031] When the pressure plate 39 is pressed, the pressure plate 39 will cause the flipping ring 37 to flip around the fixed axis. The left end of the flipping ring 37 will tilt upward and drive the connecting rod 36 to move up, thereby causing the connecting rod 36 to pull the vertical rod 33 upward. This will cause the vertical rod 33 to move up together with the multiple connecting components 5 connected to it. The anti-detachment plate 34 at the bottom of the vertical rod 33 can prevent the vertical rod 33 from detaching from the first fixed block 31, and the first spring 35 can reset the vertical rod 33.

[0032] like Figure 1 , Figure 6 and Figure 7As shown, the connecting assembly 5 includes a connecting plate 51, a sealing tube 52, and an arc-shaped rod 54. The sealing tube 52 is movably inserted into the oil inlet pipe 44. The connecting plate 51 is installed at the top of the sealing tube 52. The arc-shaped rod 54 is connected to the end of the connecting plate 51 away from the sealing tube 52, and the arc-shaped rod 54 is wrapped around the outside of the sampling cylinder 1. A notch 55 is opened at the end of the arc-shaped rod 54 away from the connecting plate 51, and the notch 55 is sleeved on the outside of the vertical rod 33. A nut 56 is threaded onto the end of the arc-shaped rod 54 with the notch 55. The bottom of the connecting plate 51... A third spring 53 is fixedly connected between the top of the sampling tube 41 and the top of the sampling tube 44, and is sleeved on the outside of the oil inlet tube 44. An oil inlet 521 is opened at the top of the side wall of the oil inlet tube 44. The arc rod 54 is threadedly connected to the nut 56, and one end of the arc rod 54 can be connected to the vertical rod 33. The vertical rod 33 drives the connecting assembly 5 to move upward, which can make the sealing tube 52 move upward in the oil inlet tube 44, thereby exposing the oil inlet 521 on the side wall of the sealing tube 52, so that the oil flows into the sampling tube 41 through the oil inlet 521 and the oil inlet tube 44.

[0033] like Figures 5 to 7 As shown, the oil inlet pipe 44 is installed at the top of the sampling pipe 41 off-center. The outer wall of the sealing pipe 52 is in contact with the inner wall of the oil inlet pipe 44. When the sealing pipe 52 is inserted into the oil inlet pipe 44, the sealing pipe 52 can block the oil inlet pipe 44, thereby preventing the oil from seeping into the sampling pipe 41 as soon as the sampling pipe 41 is inserted into the barrel of oil.

Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
