Description

Technical Field

[0001] This utility model relates to the field of transformer oil extraction, specifically to a transformer oil chromatography oil extraction device. Background Technology

[0002] After a period of use, transformer oil needs to be sampled and its dissolved gas composition determined by chromatography using a transformer oil chromatograph. This is an effective means for power generation and supply companies to determine whether there are latent overheating, discharge, or other faults in operating oil-filled electrical equipment, thus ensuring the safe and efficient operation of the power grid. It is also a necessary means for oil-filled electrical equipment manufacturers to conduct factory inspections of their equipment.

[0003] The existing oil sampling device simply uses a sampling glass bottle for sampling, which has a single function and cannot effectively stir the oil sample. This results in sedimentation of the oil sample during the sampling and testing process, which is detrimental to the accuracy of the test results. In addition, the existing oil sampling device cannot easily wipe the oil sample in the glass bottle, making cleaning inconvenient. Further improvements are needed.

[0004] Therefore, it is necessary to invent a transformer oil chromatography oil extraction device. Utility Model Content

[0017] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0018] Please refer to the appendix. Figures 1-4 This utility model provides a transformer oil chromatography oil sampling device, including a sampling bottle 1, which is made of transparent material, preferably glass. A bottle cap 2 is threadedly connected to the top of the sampling bottle 1, and an oil inlet pipe 3 is fixedly connected to the top of the bottle cap 2. A first shut-off valve 4 is fixedly connected to the body of the oil inlet pipe 3. Specifically, the user can place the oil inlet pipe 3 at the corresponding transformer drain valve port, so that the transformer oil flows into the sampling bottle 1 through the oil inlet pipe 3. A sealing cap 5 is threadedly connected to the top of the oil inlet pipe 3 for waterproofing and dustproofing. An oil outlet pipe 6 is fixedly connected to the bottom of the side of the sampling bottle 1, and a second shut-off valve 7 is fixedly connected to the body of the oil outlet pipe 6 for taking out the sampled oil for testing. A stirring component is fixed on the bottle cap 2, and a wiping component is fixed on the stirring component. A sealing component is provided between the bottle cap 2 and the sampling bottle 1. The stirring assembly includes a fixing box 8, which is fixed to the top of the bottle cap 2. A USB charging port 9 is fixed to one side of the fixing box 8. A rubber plug 10 is embedded in the USB charging port 9 to make the USB charging port 9 waterproof and dustproof. A storage battery 11 is fixed inside the fixing box 8. The USB charging port 9 is electrically connected to the storage battery 11. A control switch 12 is fixed to the top of the fixing box 8. The storage battery 11 is electrically connected to the control switch 12. Specifically, the user can charge the storage battery 11 through the USB charging port 9. The principle is well known to those skilled in the art and is widely sold on the market, so it will not be described in detail. The stirring assembly also includes a stirring motor 13, which is vertically fixed to the center of the top of the bottle cap 2. The stirring motor 13 is located inside the fixing box 8. The control switch 12 is electrically connected to the stirring motor 13. The output shaft of the stirring motor 13 passes vertically through the center of the bottle cap 2, and a connecting shaft 14 is vertically fixed to the bottom of the output shaft of the stirring motor 13. A stirring paddle 15 is fixed to the bottom of the connecting shaft 14. Specifically, the user can control the operation of the stirring motor 13 through the control switch 12. When the stirring motor 13 is running, it can drive the stirring paddle 15 to rotate inside the sampling bottle 1 through the connecting shaft 14, thereby continuously stirring the oil sample and effectively preventing the oil sample from settling during the sampling and testing process, which is beneficial to the accuracy of the test results. The wiping assembly includes a U-shaped connecting plate 16, which is fixed on the stirring paddle 15. A U-shaped rubber scraper 17 is fixed on the surface of the U-shaped connecting plate 16. The stirring paddle 15 is located inside the sampling bottle 1, and the surface of the U-shaped rubber scraper 17 abuts against the inner surface of the sampling bottle 1. Specifically, when the stirring motor 13 drives the stirring paddle 15 to rotate, the U-shaped rubber scraper 17 can also be driven to rotate synchronously through the U-shaped connecting plate 16. This allows the U-shaped rubber scraper 17 to continuously wipe the inner wall of the sampling bottle 1, effectively preventing oil samples from adhering to the inner wall of the sampling bottle 1. The bottle cap 2 is easy to disassemble and assemble, thus facilitating the cleaning of the sampling bottle 1. The sealing assembly includes a first rubber sealing ring 18 and a second rubber sealing ring 19. The first rubber sealing ring 18 is sleeved on the top of the sampling bottle 1, and the second rubber sealing ring 19 is fixed inside the bottle cap 2. When the bottle cap 2 is threadedly fixed to the top of the sampling bottle 1, the top of the first rubber sealing ring 18 abuts against the bottom of the bottle cap 2, and the bottom of the second rubber sealing ring 19 abuts against the top of the sampling bottle 1. Specifically, under the sealing action of the first rubber sealing ring 18 and the second rubber sealing ring 19, the sealing performance when the bottle cap 2 and the sampling bottle 1 are threadedly fixed can be effectively guaranteed. The top of the fixed box 8 is fixed with a handle 20 for easy carrying by the user.

[0019] The usage process of this utility model is as follows: When in use, the user opens the first shut-off valve 4, then places the oil inlet pipe 3 at the corresponding transformer drain valve port, so that the transformer oil flows into the sampling bottle 1 through the oil inlet pipe 3, and closes the first shut-off valve 4 and the cap 5. Then, the stirring motor 13 is controlled to run by the control switch 12. When the stirring motor 13 runs, it can drive the stirring paddle 15 to rotate inside the sampling bottle 1 through the connecting shaft 14, so that the oil sample can be continuously stirred, effectively preventing the oil sample from settling during the sampling and testing process, which is beneficial to the accuracy of the test results. When the stirring motor 13 drives the stirring paddle 15 to rotate, it can also drive the U-shaped rubber scraper 17 to rotate synchronously through the U-shaped connecting plate 16, so that the U-shaped rubber scraper 17 can continuously wipe the inner wall of the sampling bottle 1, effectively preventing the oil sample from adhering to the inner wall of the sampling bottle 1. The bottle cap 2 is easy to disassemble and assemble, so that the sampling bottle 1 can be cleaned by injecting cleaning water after use.

[0020] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art can modify this utility model or modify it into an equivalent technical solution using the technical solution described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solution of this utility model are within the scope of protection claimed by this utility model.
