Detailed Description of the Embodiments
[0052] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numerals in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application.

[0054] In addition, it should also be noted that the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0055] In the present application, unless otherwise clearly specified and defined, terms such as "installation", "connection", "fixation", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection, an electrical connection, or a connection that can communicate with each other; it may be a direct connection, or an indirect connection through an intermediate medium, and may be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above - mentioned terms in the present application can be understood according to specific circumstances.
[0056] In the construction of power grids, transformers are important electrical equipment used to ensure the stable operation of power grids. Transformer oil is mainly used for the heat dissipation and cooling of transformers. During the long-term operation of transformers, transformer oil and solid insulation materials will gradually age and decompose under the action of thermoelectric stress, generating harmful gases. When there are overheating, discharge faults or moisture ingress, the generation of these harmful gases will be accelerated, and they will diffuse and dissolve in the transformer oil, corroding the transformer. Therefore, it is necessary to regularly sample and inspect the transformer oil.
[0057] In the prior art, the sampling bottle is placed below the sampling port of the transformer. The sampling port of the transformer oil uses a screw seal. When sampling, the screw is first loosened, and the transformer oil flows out from the gap between the screw and the sampling port and drips into the sampling bottle. However, in the above sampling method, both the sampling bottle and the sampling port are exposed to the air, and the oil is easily contaminated, affecting the test results.
[0058] Moreover, due to the influence of production design and on-site installation on the position of the oil extraction valve of the transformer, such as the height and spatial distribution of the sampling port, it is very difficult for the operator to normally use the oil collection bottle to receive the oil during the oil sampling operation. And due to the distance between the oil collection bottle and the sampling port, some oil samples will splash and spill, and there is a problem that the oil will splash. At the same time, since the extracted oil sample is exposed to the air, it will also be affected by personnel and environmental factors, resulting in impure oil samples, abnormal data results collected, and then the operator has to go to the site to re-extract the oil sample for re-inspection, increasing the frequency of oil sampling operations.
[0059] In view of this, the embodiment of the present application provides an oil extraction device for extracting oil at the sampling port of a device, including: a collection component, a connection component, and a drive component; the connection component is used to be sleeved with the oil extraction valve of the sampling port, and the connection component covers the sampling port; the drive component includes a drive box, a drive member, and a transmission member. There is a drive cavity in the drive box, the drive member is arranged in the drive cavity, and the drive member is connected to the connection component through the transmission member; the collection component is communicated with the connection component. By sleeving the connection component with the oil extraction valve of the sampling port, the drive member drives the connection component to rotate through the transmission member, driving the oil extraction valve to rotate, thereby opening the sampling port, so that the oil at the sampling port flows into the collection component through the connection component. The entire oil extraction process avoids the sampling oil being contaminated by being exposed to the air. After the oil extraction is completed, the connection component is driven to rotate in the reverse direction to close the sampling port, preventing air from entering the sampling port; and since the connection component covers the sampling port, it is avoided that the oil contacts the air and is contaminated when the sampling port is opened. Thus, the oil extraction device provided by the embodiment of the present application facilitates avoiding the oil being contaminated by being exposed to the air during the oil extraction process.
[0060] The following combines Figures 1 to 12 and specific embodiments to elaborate on the present application in detail.

[0063] The embodiment of the present application provides an oil extraction device for extracting oil at the sampling port of a device, including: a collection component 100, a connection component 200, and a driving component 300; the connection component 200 is used for sleeving with the oil extraction valve at the sampling port, and the connection component 200 covers the sampling port; the driving component 300 includes a driving box 310, a driving member 320, and a transmission member 330. There is a driving cavity 311 in the driving box 310. The driving member 320 is arranged in the driving cavity 311. The driving member 320 is connected to the connection component 200 through the transmission member 330; the collection component 100 is communicated with the connection component 200; the driving member 320 is configured to drive the connection component 200 to rotate through the transmission member 330 to open the sampling port, so that the oil at the sampling port flows into the collection component 100 through the connection component 200, or close the sampling port.
[0064] Specifically, the connection component 200 is used for sleeving with the oil extraction valve at the sampling port, and the connection component 200 covers the sampling port. Exemplarily, the oil extraction valve at the sampling port is a screw. The screw is inserted into the sampling port to seal the sampling port. One end of the connection component 200 facing the sampling port is provided with a sleeve. There is a thread in the sleeve. The sleeve is threadedly connected to the screw. When the sleeve rotates, it drives the screw to rotate, and the transformer oil flows into the collection component 100 through the gap between the screw and the sampling port through the connection component 200.
[0065] To facilitate the rotation of the driving connection component 200, the embodiment of the present application further includes a driving component 300. The driving component 300 includes a driving box 310, a driving member 320, and a transmission member 330. There is a driving cavity 311 inside the driving box 310. The driving member 320 is arranged in the driving cavity 311. The driving member 320 is connected to the connection component 200 through the transmission member 330. In the embodiment of the present application, the specific structure of the driving member 320 is not specifically limited and can be set according to actual use needs. Exemplarily, as Figure 11 shown, the driving member 320 can be a motor, and output shafts are arranged at both ends of the motor. When taking oil, the driving member 320 drives the connection component 200 to rotate through the transmission member 330, drives the oil taking valve to rotate, so as to open the sampling port, so that the oil at the sampling port flows into the collection component 100 through the connection component 200; after the oil taking is completed, the connection component 200 is driven to rotate in the reverse direction through the transmission member 330, drives the oil taking valve to rotate in the reverse direction, and closes the sampling port.
[0066] The connection component 200 is used for sleeving with the oil taking valve of the sampling port. The driving member 320 drives the connection component 200 to rotate through the transmission member 330, thereby opening the sampling port, so that the oil at the sampling port flows into the collection component 100 through the connection component 200. The entire oil taking process avoids the sampled oil being exposed to the air and being contaminated. After the oil taking is completed, the connection component 200 is driven to rotate in the reverse direction to close the sampling port, and the connection component 200 covers the sampling port, avoiding the oil directly contacting the air while opening the sampling port. Thus, the oil taking device provided by the embodiment of the present application facilitates avoiding the oil being exposed to the air and being contaminated during the oil taking process.
[0067] In some possible implementation manners, for the oil taking device provided by the embodiment of the present application, the connection component 200 includes a connecting piece 210, an oil-proof cover 220, and a universal piece 230. One end of the universal piece 230 is connected to the oil-proof cover 220, and the other end is connected to the transmission member 330. The oil-proof cover 220 is communicated with the connecting piece 210. The connecting piece 210 is used for connecting with the oil taking valve, and the oil-proof cover 220 is used for temporarily storing oil.
[0068] Specifically, the connecting piece 210 is used for connecting the oil taking valve of the sampling port. Exemplarily, the oil taking valve of the sampling port is a screw. When the sampling port needs to be opened, the connecting piece 210 is threadedly connected to the screw, driving the screw to rotate, facilitating the flow of the transformer oil from the gap between the screw and the sampling port.
[0069] In some embodiments, various sleeves can be connected to the front end of the connecting piece 210, and a hexagonal hole is provided at the front end to facilitate the installation of different types of sleeves correspondingly.
[0070] One end of the universal joint 230 is connected to the oil shield 220, and the other end is connected to the transmission member 330. In the oil sampling device according to the embodiment of the present application, the direction of the connecting member 210 can be easily adjusted through the universal joint 230 to adapt to the position of the sampling port.
[0071] In some embodiments, the oil shield 220 is connected to the collection assembly 100 through the oil collecting pipe 120. The oil at the sampling port enters the oil shield 220 and then enters the collection assembly 100 through the oil collecting pipe 120, preventing the transformer oil from splashing when the screw is rotated.
[0072] In some other embodiments, since there may be rust impurities in the oil at the sampling port, which may affect the test results. Therefore, the collection assembly 100 may include an oil storage bottle 111 and a waste oil bottle 112. First, unscrew the screw at the sampling port and drain a part of the transformer oil into the waste oil bottle 112. Then, turn on the centrifugal fan 410 to blow the remaining oil into the waste oil bottle 112. Next, insert the oil collecting pipe 120 into the oil storage bottle 111 to collect the full transformer oil. Finally, blow the remaining oil in the oil shield 220 and the oil collecting pipe 120 into the waste oil bottle 112. At this time, the sampling of the next transformer oil can be started and the above steps can be repeated. The waste oil bottle 112 is used to collect the residual oil during the oil sampling process of the previous transformer or the waste oil with possible rust impurities when the oil just comes out of the sampling port, avoiding affecting the oil sampling of the next transformer and preventing the mixing of the oil from the previous transformer into the next one, which may lead to inaccurate detection.
[0073] In some possible implementation manners, for the oil sampling device provided in the embodiment of the present application, the universal joint 230 includes a universal joint 231, a universal flexible shaft 232, and a connecting shaft 233. The transmission member 330 is connected to the universal flexible shaft 232 through the universal joint 231, and the universal flexible shaft 232 is connected to the oil shield 220 through the connecting shaft 233.
[0074] Due to the influence of the production design and on-site installation on the position of the oil sampling valve of the transformer, such as the height and spatial distribution of the sampling port, it is difficult for the operator to normally use the oil sampling container to receive the oil during the oil sampling operation, and part of the oil is likely to splash and spill. Therefore, the universal joint 230 is provided in the embodiment of the present application to adapt to the position of the sampling port.
[0075] Specifically, the universal joint 230 includes a universal joint 231, a universal flexible shaft 232, and a connecting shaft 233. The transmission member 330 is connected to the universal flexible shaft 232 through the universal joint 231.
[0076] The universal joint 231 includes a first universal joint fork, a second universal joint fork and a cross shaft. The first universal joint fork is connected to the output shaft of the transmission member 330. The first universal joint fork is connected to the second universal joint fork through the cross shaft. The second universal joint fork is connected to the flexible universal shaft 232. The flexible universal shaft 232 is connected to the oil shield 220 through the connecting shaft 233. In the embodiment of the present application, for the universal joint 230, it is convenient to adjust the direction of the connecting shaft 233 connecting the component 200 through the flexible universal shaft 232 and the connecting shaft 233, and flexibly adapt to the position of the sampling port.
[0077] In some possible implementation manners, the oil extraction device provided in the embodiment of the present application further includes an evacuation component 400. The evacuation component 400 includes a centrifugal fan 410 and an air duct 420. The centrifugal fan 410 has an air outlet 411. The air outlet 411 is connected to the air duct 420. The air duct 420 is connected to the connecting component 200. The centrifugal fan 410 is connected to the driving component 320 through the transmission member 330.
[0078] Specifically, the centrifugal fan 410 drives the air flow through centrifugal force. The centrifugal fan includes a rotating shaft and a plurality of fan blades sleeved on the rotating shaft. The rotating shaft is connected to the driving component 320 through the transmission member 330.
[0079] The air duct 420 is connected to the connecting component 200. Exemplarily, the air duct 420 is communicated with the oil shield 220. The oil shield 220 is communicated with the collecting component 100 through the oil collecting pipe 120. When using the evacuation component 400, the centrifugal fan 410 drives the air flow through rotation, so that the air flows from the air outlet 411 through the air duct 420 and into the connecting component 200, which is convenient for flowing the residual transformer oil in the connecting component 200 or the residual transformer oil in the oil collecting pipe 120 into the collecting component 100.
[0080] In some embodiments, an air inlet is provided on the centrifugal fan 410. The air inlet faces the outside, and an air inlet dust-proof cover is provided on the air inlet.
[0081] In some possible implementation manners, for the oil extraction device provided in the embodiment of the present application, the transmission member 330 includes a moving rod 331, a first gear 332, a second gear 333 and a transmission sleeve 334. The transmission sleeves 334 are arranged at both ends of the moving rod 331. The first gear 332 and the second gear 333 are correspondingly meshed with the transmission sleeve 334. The moving rod 331 has a first position and a second position. The moving rod 331 moves relative to the driving box 310 to switch between the first position and the second position. In the first position, the transmission sleeve 334 is meshed with the first gear 332, and the driving component 320 is connected to the first gear 33. In the second position, the driving component 320 is connected to the evacuation component 400 through the second gear 333.
[0082] Transmission sleeves 334 are arranged at both ends of the moving rod 331. Exemplarily, the structure of the transmission sleeve is asFigure 5 As shown, a connection hole is provided on the transmission sleeve. The connection hole is used for inserting and connecting with the moving rod 331, and a tooth-shaped structure adapted to the first gear 332 or the second gear 333 is provided inside the transmission sleeve.
[0083] The first gear 332 includes a first driving gear and a first driven gear. The first driving gear and the first driven gear are meshed with each other. The first driving gear is sleeved on the first output shaft of the driving member 320, and one end of the moving rod 331 is sleeved with the first driving gear and the first driven gear.
[0084] The second gear 333 includes a second driving gear and a second driven gear. The first driving gear and the second driven gear are meshed with each other. The first driving gear is sleeved on the second output shaft of the driving member 320. The second driven gear is connected to the evacuation assembly 400, and one end of the moving rod 331 is sleeved with the second driving gear and the second driven gear.
[0085] In some embodiments, the structure of the moving rod 331 is as Figure 4 shown. The moving rod 331 is symmetrical. An adjusting block is provided at the top of the moving rod 331, which is convenient for applying force to adjust the movement of the moving rod 331 relative to the driving box 310 to switch between the first position and the second position. The end of the moving rod 331 is an arc-shaped fixing rod, and both ends of the arc-shaped fixing rod are fixed cylinders inward, and the fixing cylinders are used for connecting with the transmission sleeve 334.
[0086] During use, when the moving rod 331 is pushed forward, the moving rod 331 is in the first position. The transmission sleeve 334 is meshed with the first driving gear and the first driven gear, and there is a gap between the second driving gear and the second driven gear and the transmission sleeve 334. The driving member 320 is connected to the connecting assembly 200 through the first gear 332 to drive the connecting assembly 200 to rotate.
[0087] When the moving rod is pushed backward, the moving rod 331 is in the second position.
