[0025] Reference Figure 1-6This utility model discloses a transformer accessory oil maintenance device, which includes a transformer body 1. A first oil outlet pipe 2 is provided below the transformer body 1. An oil valve 3 is provided on the first oil outlet pipe 2. A flange 4 is fixedly connected to one end of the first oil outlet pipe 2. An oil inlet pipe 10 is fixedly connected to one end of the flange 4. A cover plate 5 is fixedly connected to one end of the oil inlet pipe 10. A coarse filter 7 is fixedly connected below the cover plate 5. An installation frame 28 is movably connected inside the coarse filter 7. A filter screen 29 is fixedly connected to the lower end of the installation frame 28. A viewing panel 6 is provided at one end of the coarse filter 7. Through the coordinated operation of the first oil outlet pipe 2, oil valve 3, flange 4, oil inlet pipe 10, cover plate 5, coarse filter 7, installation frame 28, filter screen 29 and viewing panel 6, efficient coarse filtration of transformer oil and convenient maintenance of filter screen 29 are achieved, thereby improving the efficiency of oil maintenance.

[0026] Specifically, the coarse filter 7 has symmetrical grooves 14 at both ends, and symmetrical sliders 18 are slidably connected in the symmetrical grooves 14. The symmetrical sliders 18 are fixedly connected to both ends of the mounting frame 28. The grooves 14 in the coarse filter 7 and the sliders 18 of the mounting frame 28 slide in cooperation, providing a stable guide for the pulling of the mounting frame 28, ensuring the smoothness of the filter screen 29 disassembly and assembly process, and improving maintenance efficiency.

[0027] Specifically, the transformer body 1 has a symmetrical first groove 15 at one end of the symmetrical sliding groove 14. A symmetrical connecting block 20 is slidably connected in the symmetrical first groove 15. One end of the symmetrical connecting block 20 is fixedly connected to both ends of the mounting frame 28. The first groove 15 at the transformer body 1 and the connecting block 20 of the mounting frame 28 slide together, working in conjunction with the sliding groove 14 and the slider 18 to enhance the structural stability of the mounting frame 28 when it is pulled out.

[0028] Specifically, the symmetrical connecting block 20 has corresponding through holes 19, and one end of the symmetrical first groove 15 has a corresponding second groove 16. The corresponding through holes 19 and the corresponding second groove 16 are horizontally aligned. The through holes 19 of the connecting block 20 and the second groove 16 of the first groove 15 are horizontally aligned, providing precise positioning for the insertion of the locking block 26 and ensuring the structural alignment when the mounting frame 28 is fixed.

[0029] Specifically, a corresponding slot 17 is provided at one end of the corresponding second groove 16, and a corresponding locking block 26 is movably connected inside the corresponding slot 17. The corresponding slot 17 and the corresponding locking block 26 are adapted to each other. A corresponding fixing rod 25 is fixedly connected to one end of the corresponding locking block 26. The corresponding locking block 26 is adapted to the through hole 19 and the second groove 16. The slot 17 and the locking block 26 are precisely matched. The fixing rod 25 enables the quick locking and unlocking of the installation frame 28, which not only ensures the stability of the filter screen 29 after installation, but also improves the convenience of disassembly and assembly.

[0030] Specifically, the corresponding fixing rod 25 is slidably connected to the corresponding mounting base 21. The corresponding fixing rod 25 is fixedly connected to the corresponding second connecting ring 24 inside the corresponding mounting base 21. One end of the corresponding second connecting ring 24 is fixedly connected to the corresponding spring 27. The fixing rod 25 can slide and rotate while sliding inside the mounting base 21, so that the locking block 26 enters the locking slot 17 for fixing.

[0031] Specifically, the other end of the corresponding spring 27 is fixedly connected to a corresponding first connecting ring 23, and a corresponding fixing rod 25 is slidably connected inside the corresponding first connecting ring 23. One end of the corresponding fixing rod 25 is fixedly connected to a corresponding circular dial 22. When the first connecting ring 23 slides on the fixing rod 25, the first connecting ring 23 presses against one end of the mounting base 21 to compress the spring 27 without affecting the rotation of the fixing rod 25.

[0032] Specifically, the four walls of the coarse filter 7 are provided with a first sealing strip 11 at the upper end of the mounting frame 28, and the four walls of the coarse filter 7 are provided with a second sealing strip 12 at the lower end of the mounting frame 28. A guide surface 13 is provided at the lower end of the coarse filter 7, and a second oil outlet pipe 8 is provided at one end of the coarse filter 7. An oil pump 9 is provided on the second oil outlet pipe 8. The first sealing strip 11 and the second sealing strip 12 in the coarse filter 7 form a double seal to prevent oil leakage. The guide surface 13 guides the filtered oil to collect, and together with the second oil outlet pipe 8 and the oil pump 9, achieves efficient oil delivery, ensuring the sealing and smoothness of oil maintenance.

[0033] Working principle:

[0034] When oil valve 3 is opened, the oil to be inspected in the transformer body 1 enters the coarse filter 7 through the first oil outlet pipe 2 → flange 4 → oil inlet pipe 10. The oil flows through the filter screen 29 of the mounting frame 28 within the coarse filter 7, where impurities are intercepted. The filtered oil is collected through the guide surface 13 and finally drawn out by the oil pump 9 on the second oil outlet pipe 8, completing the coarse filtration maintenance. When the filter screen 29 needs to be replaced or cleaned: Unlocking operation: First, rotate the circular dial 22 to disengage the locking block 26 on the fixed rod 25 from the slot 17. Then, rotate the circular dial 22 again, allowing it to slide within the mounting base 21, compressing the spring 27. This causes the locking block 26 to simultaneously disengage from the second groove 16 and through hole 19, pulling the mounting frame 28. The sliders 18 at both ends slide along the groove 14, and the connecting block 20 slides along the first groove 15, thus removing the mounting frame 28 from the coarse filter. After removing the filter screen 29 from the filter 7 and replacing it, push the mounting frame 28 into the coarse filter 7. This allows the slider 18 and connecting block 20 to slide into the slide groove 14 and the first groove 15, respectively. Push the fixing rod 25 and its locking block 26 into the second groove 16 and the through hole 19. Because the fixing rod 25 and locking block 26 are compatible with the second groove 16 and the through hole 19, the fixing rod 25 moves backward. This causes the first connecting ring 23, which is fixedly connected to the spring 27 and slidably connected to the fixing rod 25, to press against the mounting base 21, compressing the spring 27 to form a fixed position. Push the frame 28 into the slot 17 position and rotate the circular dial 22 to rotate the locking block 26, causing the locking block 26 to engage with the slot 17 and form a fixed position. The first sealing strip 11 and the second sealing strip 12 inside the coarse filter 7 form a seal at the upper and lower ends of the mounting frame 28, respectively, to ensure no leakage during oil filtration.

[0035] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
