Technical Field

[0001] The present application relates to the technical field of oil level detection, and in particular to a transformer oil conservator oil level detection device. Background Art

[0002] The transformer oil conservator is one of the important equipment in the power system. It is mainly used to store and replenish the oil volume caused by temperature changes during the operation of the transformer. With the continuous development of the power system, higher requirements are placed on the safety and reliability of the transformer. Accurately monitoring the oil level in the oil conservator is of great significance to ensure the normal operation of the transformer, and can effectively avoid equipment failures and safety accidents caused by abnormal oil level.

[0003] A related transformer oil conservator oil level detection device uses a built-in oil level sensor to achieve accurate measurement and then feeds the data back to the monitoring system.

[0004] However, when the platform on which the transformer is located tilts, it may cause deviations in the sensor readings, affecting the measurement accuracy. Summary of the invention

[0005] In order to reduce the problem that when the platform on which the transformer is located is tilted, the sensor readings may be biased, thereby affecting the measurement accuracy, the present application provides a transformer oil conservator oil level detection device.

[0006] The present application provides a transformer oil conservator oil level detection device, which adopts the following technical solution: A transformer oil conservator oil level detection device, comprising: Detection rod, A detection probe, which is rotatably arranged at one end of the detection rod through an angle adjustment component; A magnetic strip, which is fixedly arranged on the upper end of the detection probe and is used to fix the detection probe to the oil conservator; The angle adjustment component comprises: A motor, the motor being fixedly arranged at one end of the detection rod close to the detection probe; A primary adjusting member, the primary adjusting member is fixedly arranged on the output shaft of the motor and is used to drive the detection probe to initially rotate; A secondary adjusting member, wherein the secondary adjusting member is connected to the primary adjusting member via a matching member, and the secondary adjusting member is used to drive the detection probe to further rotate.

[0007] By adopting the above technical solution, the detection rod serves as a supporting structure to provide a stable installation foundation for the detection probe. The detection probe is rotated and set at one end of the detection rod through the angle adjustment component, and can perform accurate measurements at different positions. The magnetic strip is fixedly set at the upper end of the detection probe to ensure that the detection probe is firmly connected to the oil pillow to prevent it from falling off or shifting. The motor is fixedly set at one end of the detection rod close to the detection probe to provide power to drive the first-level adjustment member and the second-level adjustment member to move. The first-level adjustment member realizes the initial rotation of the detection probe through the transmission mechanism of the connecting column, the first bevel gear, the second bevel gear and the matching rod to expand the detection range. The second-level adjustment member further fine-tunes the position of the detection probe to improve the measurement accuracy.

[0008] Optionally, the primary adjusting member includes: A connecting column, wherein the connecting column is sleeved on the outer peripheral side of the output shaft of the motor and the connecting column is fixedly connected to the output shaft of the motor; A first bevel gear, the first bevel gear is fixedly disposed at an end of the connecting column away from the motor; a second bevel gear, the second bevel gear meshing with the first bevel gear, the second bevel gear and the first bevel gear being rotatably arranged; A matching rod, one end of which is fixedly disposed on the axis of the second bevel gear, and the other end of which is fixed to the detection probe.

[0009] By adopting the above technical solution, the fixed connection between the connecting column and the motor output shaft ensures the transmission stability, so that the primary adjustment member can work stably under the drive of the motor. The meshing structure between the first bevel gear and the second bevel gear realizes the functions of direction conversion and smooth power transmission, thereby accurately controlling the initial rotation of the detection probe. The design of the matching rod converts the rotational motion into linear or curved motion, so that the detection probe can initially reach the desired position, ensuring the accuracy of the detection results.

[0010] Optionally, the secondary adjustment member includes: A mounting plate, the mounting plate being fixedly arranged on the peripheral side of the detection rod; A gear ring, the gear ring is fixedly arranged on one side of the mounting plate, and the gear ring is coaxially arranged with the output shaft of the motor; A first gear, wherein the first gear is sleeved on the output shaft of the motor, and the first gear is coaxially arranged with the ring gear; a second gear, one side of the second gear meshing with the first gear, and the other side of the second gear meshing with the inner circumference of the gear ring; A matching sleeve, wherein the matching sleeve is fixedly arranged on the outer peripheral side of the connecting column, and one end of the matching sleeve contacts a side of the first bevel gear close to the motor; A matching column, one end of which is fixedly connected to an end of the matching sleeve close to the first bevel gear, and the other end of which is rotatably connected to the second bevel gear.

[0011] A fixing rod, one end of which is fixedly connected to an end of the matching sleeve close to the motor, and the other end of which is fixedly connected to the second gear.

[0012] By adopting the above technical solution, the setting of the mounting plate makes the entire secondary adjustment structure more stable and improves the angle adjustment accuracy of the detection probe. The coaxial setting of the gear ring and the motor output shaft ensures the stability during the transmission process and reduces the error. The meshing design of the first gear and the second gear realizes the effective transmission of torque and ensures that the detection probe can work stably at different angles. The design of the matching sleeve enhances the contact area between the connecting column and the first bevel gear, further improving the mechanical strength and reliability. The setting of the matching column enables the second bevel gear to rotate flexibly, thereby driving the detection probe to complete fine angle adjustment. The two ends of the fixed rod are fixedly connected to the matching sleeve and the second gear respectively, which can ensure the stability during the transmission process and prevent the detection accuracy from being affected by the looseness of components. At the same time, this structural design makes the entire device more compact and improves space utilization.

[0013] Optionally, the matching piece includes: A rotating rod, the rotating rod is rotatably arranged on a side of the mounting plate close to the gear ring; A clamping plate, one end of which is fixedly arranged on the peripheral side of the rotating rod, and the other end of which is horizontally provided with a matching groove; An abutment plate, one end of which is fixedly arranged on an end of the mounting plate close to the gear ring, and the other end of the abutment plate is a free end; A movable plate, the movable plate passes through the abutment plate, one end of the movable plate abuts against an end of the matching sleeve close to the first bevel gear; a clamping column is fixedly provided at the other end of the movable plate; the clamping column is slidably provided in the matching groove; A movable pressing plate is fixedly connected to one end of the movable plate close to the clamping column, and the movable pressing plate is slidably arranged on the outer peripheral side of the output shaft of the motor through a key shaft.

[0014] By adopting the above technical solution, the coordinated use of the rotating rod and the clamping plate enables the clamping column to slide stably in the matching groove, thereby ensuring the stability of the secondary adjustment part in different positions. The design of the movable plate can not only interfere with the matching sleeve, but also realize the position locking of the secondary adjustment part through the clamping column, thereby improving the reliability and accuracy of the entire device. The abutment plate serves as a supporting structure to prevent the movable plate from shifting or falling off during movement, thereby enhancing the overall stability of the device. The movable pressure plate is set on the outer peripheral side of the output shaft of the motor through the sliding of the key shaft, which ensures smoothness and consistency during movement, reduces mechanical wear, and prolongs service life.

[0015] Optionally, a display is provided at one end of the detection rod away from the detection probe for displaying detection data.

[0016] By adopting the above technical solution, the transformer oil conservator oil level detection device can set a display at the end of the detection rod away from the detection probe, so as to display the detection data in real time. This not only improves the operator's perception of oil level changes, but also facilitates timely detection and handling of abnormal situations, thereby improving the safety and reliability of transformer operation.

[0017] Optionally, the detection rod is a telescopic rod.

[0018] By adopting the above technical solution, the detection rod is designed as a telescopic rod, the length of which can be flexibly adjusted to meet the oil pillow detection needs of different heights and positions, thereby improving the application scope and operational convenience of the device.

[0019] Optionally, the detection rod is made of insulating material.

[0021] Optionally, the movable pressing plate is made of elastic material.

[0022] By adopting the above technical solution, the movable pressure plate is made of elastic material, which can increase the friction between the movable pressure plate and the key shaft, improve the stability of the structure, and prevent the movable pressure plate from loosening due to vibration or impact during use, thereby ensuring that the angle adjustment of the detection probe is more accurate and reliable.

[0023] In summary, the embodiment of the present invention provides a transformer oil conservator oil level detection device, which includes at least one of the following beneficial technical effects: 1. The detection rod serves as a supporting structure, providing a stable installation foundation for the detection probe. The detection probe is rotated and set at one end of the detection rod through the angle adjustment component, and can perform accurate measurements at different positions.

[0027] The following is combined with Figure 1-3 This application is described in further detail.

[0028] Combination Figure 1 , Figure 2 and Figure 3 The embodiment of the present application discloses a transformer oil pillow oil level detection device, comprising: a detection rod 1, a detection probe 11, and a magnetic strip 12. The detection probe 11 is rotatably arranged at one end of the detection rod 1 through an angle adjustment component; the magnetic strip 12 is fixedly arranged at the upper end of the detection probe 11, and is used to fix the detection probe 11 to the oil pillow; the angle adjustment component comprises a motor 13, a primary adjustment member 2, and a secondary adjustment member 3. The motor 13 is fixedly arranged at one end of the detection rod 1 close to the detection probe 11; the primary adjustment member 2 is fixedly arranged on the output shaft of the motor 13; and is used to drive the detection probe 11 to rotate initially; the secondary adjustment member 3 is connected to the primary adjustment member 2 through a matching member 4, and the secondary adjustment member 3 is used to drive the detection probe 11 to rotate further.

[0029] In the embodiment of the present application, the detection rod 1 serves as the supporting part of the entire device, and its length and material need to be selected according to the actual application scenario to ensure sufficient strength and stability. The design of the detection probe 11 used to directly measure the oil level probe in the transformer oil pillow needs to consider the compatibility with the oil in the oil pillow, the accuracy of the measurement, and the reliability of long-term use. The magnetic strip 12 is fixedly arranged on the upper end of the detection probe 11, and the detection probe 11 is firmly fixed in the appropriate position of the oil pillow by the principle of magnetic adsorption to ensure the stability and accuracy of the probe during the measurement process. The motor 13 is fixedly arranged at one end of the detection rod 1 close to the detection probe 11, providing power to drive the rotation of the angle adjustment component. The primary adjustment member 2 is fixedly arranged on the output shaft of the motor 13, and the primary adjustment member 2 is driven to rotate by the rotation of the motor 13, thereby preliminarily adjusting the angle of the detection probe 11. The secondary adjustment member 3 is connected to the primary adjustment member 2 through the matching member 4 to further adjust the angle of the detection probe 11.

[0030] When in use, insert the detection rod 1 into the transformer oil pillow to ensure that the detection probe 11 can contact the oil surface. Fix the detection probe 11 in a proper position of the oil pillow through the magnetic strip 12. Start the motor 13, and adjust the angle of the detection probe 11 to the optimal measurement position through the cooperation of the primary adjustment member 2 and the secondary adjustment member 3. Perform oil level measurement. Through the precise adjustment of the angle adjustment component, it can be ensured that the detection probe 11 contacts the oil surface at the optimal angle, thereby improving the accuracy of the measurement.

[0031] Combination Figure 1 , Figure 2 and Figure 3In a specific application embodiment, the primary adjustment member 2 includes: a connecting column 21, a first bevel gear 22, a second bevel gear 23, and a matching rod 24. The connecting column 21 is sleeved on the outer peripheral side of the output shaft of the motor 13, and the connecting column 21 is fixedly connected to the output shaft of the motor 13; the first bevel gear 22 is fixedly arranged at the end of the connecting column 21 away from the motor 13; the second bevel gear 23 is meshed with the first bevel gear 22, and the second bevel gear 23 is rotatably arranged with the first bevel gear 22; one end of the matching rod 24 is fixedly arranged on the axis of the second bevel gear 23, and the other end of the matching rod 24 is fixed to the detection probe 11.

[0032] In the embodiment of the present application, the connecting column 21 is sleeved on the outer peripheral side of the output shaft of the motor 13 and is fixedly connected to the output shaft of the motor 13. In this way, when the motor 13 rotates, the connecting column 21 will rotate synchronously. The first bevel gear 22 is fixedly arranged at one end of the connecting column 21 away from the motor 13. Since the connecting column 21 is fixedly connected to the output shaft of the motor 13, the rotation of the first bevel gear 22 will be directly driven by the rotation of the motor 13. The second bevel gear 23 is meshed with the first bevel gear 22, and the second bevel gear 23 and the first bevel gear 22 can rotate relative to each other. This meshing relationship makes it possible for the second bevel gear 23 to rotate in the opposite direction when the first bevel gear 22 rotates. One end of the matching rod 24 is fixedly arranged on the axis of the second bevel gear 23, and the other end is fixedly connected to the detection probe 11. Therefore, when the second bevel gear 23 rotates, the matching rod 24 will rotate accordingly, thereby driving the detection probe 11 to rotate.

[0033] During specific use, when it is necessary to preliminarily adjust the angle of the probe, start the motor 13, and the output shaft of the motor 13 drives the first bevel gear 22 to rotate. The first bevel gear 22 drives the second bevel gear 23 to rotate when rotating, so that the second bevel gear 23 drives the matching rod 24 to rotate synchronously when rotating, thereby preliminarily adjusting the position of the detection probe 11.

[0034] Combination Figure 1 , Figure 2 and Figure 3In a specific application embodiment, the secondary adjustment member 3 includes a mounting plate 31, a gear ring 32, a first gear 33, a second gear 34, a matching sleeve 35, a matching column 36, and a fixing rod 37. The mounting plate 31 is fixedly arranged on the peripheral side of the detection rod 1; the gear ring 32 is fixedly arranged on one side of the mounting plate 31, and the gear ring 32 is coaxially arranged with the output shaft of the motor 13; the first gear 33 is sleeved on the output shaft of the motor 13, and the first gear 33 and the gear ring 32 are coaxially arranged; one side of the second gear 34 is meshed with the first gear 33, and the other side of the second gear 34 is meshed with the inner peripheral side of the gear ring 32; the matching sleeve 35 is fixedly arranged on the outer peripheral side of the connecting column 21, and one end of the matching sleeve 35 is in contact with the side of the first bevel gear 22 close to the motor 13; one end of the matching column 36 is fixedly connected to one end of the matching sleeve 35 close to the first bevel gear 22, and the other end of the matching column 36 is rotatably connected to the second bevel gear 23. One end of the fixing rod 37 is fixedly connected to one end of the matching sleeve 35 close to the motor 13 , and the other end of the fixing rod 37 is fixedly connected to the second gear 34 .

[0035] In the embodiment of the present application, the mounting plate 31 is fixedly arranged on the peripheral side of the detection rod 1, providing a stable mounting platform for other components. The ring gear 32 is fixedly arranged on one side of the mounting plate 31 and is coaxially arranged with the output shaft of the motor 13. The inner and outer peripheral sides of the ring gear 32 are designed with teeth so as to mesh with the first gear 33 and the second gear 34. The first gear 33 is sleeved on the output shaft of the motor 13 and is coaxially arranged with the ring gear 32. When the motor 13 rotates, the first gear 33 will rotate accordingly and transmit power to the ring gear 32 through the meshing relationship with the ring gear 32. One side of the second gear 34 meshes with the first gear 33, and the other side meshes with the inner peripheral side of the ring gear 32. This arrangement allows the second gear 34 to receive power in two directions, thereby achieving more complex rotation control. The matching sleeve 35 is fixedly arranged on the outer peripheral side of the connecting column 21, and one end thereof contacts the side of the first bevel gear 22 close to the motor 13. The matching sleeve 35 is designed to connect and support other components to ensure the stability of the entire structure. One end of the matching column 36 is fixedly connected to one end of the matching sleeve 35 near the first bevel gear 22, and the other end is rotatably connected to the second bevel gear 23. This allows the second bevel gear 23 to rotate relative to the matching sleeve 35 within a certain range. One end of the fixing rod 37 is fixedly connected to one end of the matching sleeve 35 near the motor 13, and the other end is fixedly connected to the second gear 34. It is used to connect the second gear 34 and the matching sleeve 35 to form a stable structure.

[0036] In specific use, when the angle of the detection probe 11 needs to be adjusted, the motor 13 is first started. The rotation of the motor 13 will drive the first gear 33 and the ring gear 32 to rotate synchronously. Since the second gear 34 is meshed with both the first gear 33 and the ring gear 32, when the first gear 33 and the ring gear 32 rotate, the second gear 34 will also rotate at a certain speed. As the second gear 34 rotates, the fixed rod 37 will drive the matching sleeve 35 and the matching column 36 to rotate relative to each other. Since the matching column 36 is rotationally connected to the second bevel gear 23, this relative rotation will cause the second bevel gear 23 to rotate at a certain angle relative to the matching sleeve 35. The rotation of the second bevel gear 23 will drive the connecting column 21 and the first bevel gear 22 to rotate synchronously, and then drive the detection probe 11 to adjust the angle through the matching rod 24. Through the design of the secondary adjustment member 3, the detection probe 11 can be flexibly adjusted in multiple directions. This arrangement enables the device to adapt to transformer oil pillows of different specifications and models, thereby improving the accuracy of measurement.

[0037] Combination Figure 3 In a specific application embodiment, the mating part 4 includes a rotating rod 41, a clamping plate 42, an abutment plate 43, a movable plate 44, and a movable pressure plate 45. The rotating rod 41 is rotatably arranged on the side of the mounting plate 31 close to the gear ring 32; one end of the clamping plate 42 is fixedly arranged on the peripheral side of the rotating rod 41, and the other end of the clamping plate 42 is horizontally provided with a mating groove 46; one end of the abutment plate 43 is fixedly arranged on the end of the mounting plate 31 close to the gear ring 32, and the other end of the abutment plate 43 is a free end; the movable plate 44 passes through the abutment plate 43, and one end of the movable plate 44 abuts against the end of the mating sleeve 35 close to the first bevel gear 22; the other end of the movable plate 44 is fixedly provided with a clamping column; the clamping column is slidably arranged in the mating groove 46; the movable pressure plate 45 is fixedly connected to one end of the movable plate 44 close to the clamping column, and the movable pressure plate 45 is slidably arranged on the outer peripheral side of the output shaft of the motor 13 through the key shaft.

[0038] In a specific application embodiment, the rotating rod 41 is rotatably arranged on a side of the mounting plate 31 close to the gear ring 32. This means that the rotating rod 41 can rotate freely on the mounting plate 31, usually through a bearing or a similar rotating device. One end of the clamping plate 42 is fixedly arranged on the peripheral side of the rotating rod 41. In this way, when the rotating rod 41 rotates, the clamping plate 42 will also rotate accordingly. A matching groove 46 is horizontally arranged at the other end of the clamping plate 42. This matching groove 46 is used to cooperate with the clamping column to achieve the clamping function. One end of the abutment plate 43 is fixedly arranged at one end of the mounting plate 31 close to the gear ring 32. The other end of the abutment plate 43 is a free end, allowing the moving plate 44 to pass through. The moving plate 44 passes through the abutment plate 43, and one end thereof abuts against one end of the matching sleeve 35 close to the first bevel gear 22. A clamping column is fixedly arranged at the other end of the moving plate 44. The clamping column slides in the matching groove 46 and cooperates with the clamping plate 42 to achieve the clamping function. The movable platen 45 is fixedly connected to one end of the movable plate 44 near the clamping column. The movable platen 45 is slidably arranged on the outer peripheral side of the output shaft of the motor 13 through a key shaft. This means that the rotation of the motor 13 can drive the movement of the movable platen 45 (and the movable plate 44 and the clamping column connected thereto). The movable plate 44 is L-shaped, with a cylindrical vertical portion and a rectangular horizontal portion. A semi-arc-shaped clamping plate is arranged at one end of the horizontal portion away from the clamping column. The semi-arc-shaped clamping plate is rotatably connected to the movable platen 45, which can drive the movable platen 45 to move up and down without interfering with the rotation of the movable platen 45.

[0039] It should be noted that the movable pressure plate 45 is made of elastic material. The friction can be increased so that when the movable pressure plate 45 and the matching sleeve 35 collide with each other, the first bevel gear 22 and the matching sleeve 35 are relatively fixed. That is, when it is necessary to further adjust the angle of the detection probe 11, the rotating rod 41 is rotated toward the end close to the mounting plate 31, and the rotating rod 41 drives the clamping plate 42 to rotate toward the end close to the mounting plate 31, and at the same time, the movable plate 44 moves toward the end close to the first bevel gear 22, thereby relatively fixing the first bevel gear 22 and the second bevel gear 23; at the same time, the movable plate 44 drives the movable pressure plate 45 to move toward the end close to the first bevel gear 22 during the movement, that is, the movable pressure plate 45 will collide with the matching sleeve 35, thereby further increasing the fixity of the first bevel gear 22 and the second bevel gear 23. That is to say, when the rotating plate rotates, the movable plate 44 moves and contacts with one end of the matching sleeve 35 close to the first bevel gear 22, the movable pressure plate 45 contacts with the matching sleeve 35, the first bevel gear 22 and the second bevel gear 23 are relatively fixed, and when the motor 13 rotates, the first gear 33 and the second gear 34 rotate, driving the first bevel gear 22 to rotate, and further driving the detection probe 11 to rotate along the axial direction of the first bevel gear 22.

[0040] When in use, the clamping column is located at one end of the matching groove 46, and the ring gear 32 is not clamped. The motor 13 is started, and the output shaft of the motor 13 begins to rotate. Since the movable pressure plate 45 is slidably arranged on the outer peripheral side of the output shaft of the motor 13 through the key shaft, the rotation of the motor 13 will drive the movement of the movable pressure plate 45 (and the movable plate 44 and the clamping column connected thereto). As the movable pressure plate 45, the movable plate 44 and the clamping column move, the clamping column slides in the matching groove 46. When the clamping column slides to the other end of the matching groove 46, the clamping plate 42 and the clamping column clamp the ring gear 32 together. While clamping the ring gear 32, the rotating rod 41 can be rotated. Since the clamping plate 42 is fixedly arranged on the peripheral side of the rotating rod 41, the rotation of the rotating rod 41 will drive the rotation of the clamping plate 42 (and the clamped ring gear 32). Through the cooperation of the clamping plate 42 and the clamping column, the stable clamping of the ring gear 32 can be achieved.

[0041] A display 51 is provided at one end of the detection rod 1 away from the detection probe 11 for displaying detection data. This allows the user to observe the monitoring data in real time. The detection rod 1 is a telescopic rod. The setting of the telescopic rod allows the length of the detection rod 1 to be adjusted according to actual needs to adapt to different working environments and measurement requirements. The detection rod 1 is made of insulating material. The detection rod 1 made of insulating material can prevent the current from being transmitted to the operator through the detection rod 1.

[0042] The implementation principle of the embodiment of the present application is as follows: insert the detection rod 1 into the transformer oil pillow to ensure that the detection probe 11 can contact the oil surface. Fix the detection probe 11 in the appropriate position of the oil pillow through the magnetic strip 12. Start the motor 13, and adjust the angle of the detection probe 11 to the optimal measurement position through the cooperation of the primary adjustment member 2 and the secondary adjustment member 3. Perform oil level measurement. Through the precise adjustment of the angle adjustment component, it can be ensured that the detection probe 11 contacts the oil surface at the optimal angle, thereby improving the accuracy of the measurement.

[0043] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
