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.

[0016] like Figures 1-6 As shown, a transformer with an oil sampling device includes a transformer body 1. In use, the transformer body 1 serves as the core functional carrier and realizes voltage transformation and safe transmission of electrical energy. A pumping component 2 is fixedly connected to the outer surface of the transformer body 1. A rotating component 3 is fixedly connected to the bottom of the pumping component 2. An auxiliary component 4 is fixedly connected to the bottom of the rotating component 3. When the rotating component 3 rotates, it will drive the auxiliary component 4 to rotate together. A filter screen 5 is fixedly connected to one end of the auxiliary component 4. When sampling the oil, the filter screen 5 filters out impurities in the oil, avoiding the extraction of impurities along with the oil and affecting the test results. An adjusting component 6 is fixedly connected inside the transformer body 1. A sealing component 7 is slidably connected to the outer surface of the adjusting component 6. In use, the adjusting component 6 slides within the sealing component 7.

[0017] like Figures 1-6As shown, a first liquid extraction pipe 11 is fixedly connected to the side wall of the transformer body 1, and a second liquid extraction pipe 12 is fixedly connected to the other end of the first liquid extraction pipe 11. A liquid extraction tank 13 is fixedly connected to the top of the second liquid extraction pipe 12. The liquid extraction tank 13 is fixedly connected to the outer surface of the transformer body 1. A one-way valve 14 is fixedly connected to the bottom of the liquid extraction tank 13. The one-way valve 14 is used to control the one-way flow of oil and block the reverse flow of oil. A sampling pipe 15 is fixedly connected to the bottom of the one-way valve 14. A sealing cap 16 is threadedly connected to the bottom of the sampling pipe 15. The sealing cap 16 is used to block external impurities and air from entering. A scraper 17 is fixedly connected inside the transformer body 1.

[0018] like Figures 1-3 and Figure 5 As shown, the liquid extraction assembly 2 includes a first sliding column 21 slidably connected inside the liquid extraction tank 13. A first sliding circular plate 22 is fixedly connected to the bottom of the first sliding column 21. In use, by pressing the first sliding column 21, the first sliding circular plate 22 slides inside the liquid extraction tank 13, thereby generating negative pressure.

[0019] like Figures 2-4 As shown, the rotating assembly 3 includes a second sliding column 31 fixedly connected to the bottom of the first sliding circular plate 22. A connecting ball 32 is slidably connected to the outer surface of the second sliding column 31. A first rotating column 33 is rotatably connected to the outer surface of the second sliding column 31. A spiral groove 34 is opened inside the first rotating column 33. The connecting ball 32 is slidably connected inside the spiral groove 34. The shape of the connecting ball 32 matches that of the spiral groove 34. A limiting frame 35 is rotatably connected to the outer surface of the first rotating column 33. The limiting frame 35 is fixedly connected inside the second suction tube 12. When the first sliding circular plate 22 slides downward inside the suction tank 13, the first sliding circular plate 22 will push the second sliding column 31 to slide downward.

[0020] like Figures 2-4 and Figure 6 As shown, the auxiliary component 4 includes a second rotating column 41 fixedly connected to the bottom of the first rotating column 33. A first bevel gear 42 is fixedly connected to the bottom of the second rotating column 41. A second bevel gear 43 is meshed with the outer surface of the first bevel gear 42. A third rotating column 44 is fixedly connected to one end of the second bevel gear 43. A filter screen 5 is fixedly connected to the other end of the third rotating column 44. When the first rotating column 33 rotates, it will drive the second rotating column 41 to rotate. Since the first bevel gear 42 and the second bevel gear 43 are meshed together.

[0021] Specifically, during use, firstly, press the first sliding column 21 to make the first sliding disc 22 slide inside the liquid extraction tank 13, thereby generating negative pressure. When the first sliding disc 22 slides downward inside the liquid extraction tank 13, it will push the second sliding column 31 to slide downward. During the downward sliding of the second sliding column 31, the connecting ball 32 slides in the spiral groove 34, causing the first rotating column 33 to rotate. When the first rotating column 33 rotates, it will drive the second rotating column 41 to rotate. Since the first bevel gear 42 and the second bevel gear 43 are meshed, when the second rotating column 41 rotates, it will drive the third rotating column 44 to rotate through the first bevel gear 42 and the second bevel gear 43. When the third rotating column 44 rotates, it will drive the filter screen 5 to rotate. The scraper 17 will clean the impurities adhering to the surface of the filter screen 5 to prevent the filter screen 5 from becoming blocked and ensure the smooth flow of the sampling oil path.

[0022] like Figure 3 and Figure 6 As shown, the adjusting component 6 includes a first fixing frame 61 fixedly connected inside the first liquid extraction tube 11. The first fixing frame 61 is sleeved on the outer surface of the third rotating column 44. One end of the first fixing frame 61 is fixedly connected to a telescopic column 62. A spring 63 is sleeved on the outer surface of the telescopic column 62. The other end of the telescopic column 62 is fixedly connected to a second sliding circular plate 64. The two ends of the spring 63 are fixedly connected to the second sliding circular plate 64 and the first fixing frame 61, respectively. When the first sliding circular plate 22 slides upward in the liquid extraction tank 13, a negative pressure is generated in the liquid extraction tank 13. At this time, the second sliding circular plate 64 will slide towards the end closer to the liquid extraction tank 13 under the action of the negative pressure.

[0023] like Figure 3 and Figure 6 As shown, the sealing assembly 7 includes a second fixing frame 71 fixedly connected inside the first liquid extraction pipe 11. One end of the second fixing frame 71 is fixedly connected to a fixing plate 72. The fixing plate 72 has a plurality of through grooves 73. The second sliding circular plate 64 slides in the through grooves 73. When the second sliding circular plate 64 slides towards the side closer to the liquid extraction tank 13, the second sliding circular plate 64 will disengage from the contact with the through grooves 73, thereby allowing the oil to flow from the through grooves 73 into the interior of the second liquid extraction pipe 12.

[0024] Specifically, when the first sliding disc 22 slides upward inside the suction tank 13, a negative pressure is generated inside the suction tank 13. At this time, the second sliding disc 64 will slide towards the end closer to the suction tank 13 under the action of the negative pressure, and the spring 63 will be pulled. When the first sliding disc 22 stops sliding, the second sliding disc 64 will reset under the action of the spring 63. When the second sliding disc 64 slides towards the end closer to the suction tank 13, the second sliding disc 64 will disengage from the through groove 73, so that the oil flows from the through groove 73 into the inside of the second suction pipe 12, and then flows to the outside through the one-way valve 14 and the sampling pipe 15 for subsequent testing. After sampling, the device is sealed by tightening the sealing cap 16, and the negative pressure drive and one-way valve 14 prevent air from entering the device during use, preventing the oil from oxidizing and deteriorating, and ensuring the authenticity of the oil test.
