Description

Technical Field

[0001] This utility model relates to an auxiliary device for replacing transformer breathers, belonging to the field of power engineering safety technology. Background Technology

[0002] A transformer breather, also known as a transformer desiccant or transformer absorbent, effectively absorbs moisture from the air that enters the oil conservator's rubber bag. It removes and dries impurities and moisture from the air that enters the transformer's oil conservator due to changes in oil temperature, preventing the transformer from becoming damp and ensuring the insulation strength of the transformer oil. Therefore, to maintain the breather's absorption effect, it usually needs to be replaced periodically. However, transformer breathers are typically installed at a height of 1.5-2 meters above the ground, making disassembly and replacement difficult for workers. There is also a risk of the breather falling and damaging itself after disassembly. To address this, patent CN201711016979.1 discloses an auxiliary support. While this product assists workers in disassembling the breather and reduces the difficulty of the operation, workers still need to remove the breather from the platform for transport and replacement, and the risk of the breather falling and damaging the equipment remains.

The lifting assembly 6 is connected to a handwheel assembly 5. A telescopic support leg 7 is fixed at the bottom of the lifting assembly 6. The telescopic support leg 7 is connected and fixed by a fixing rod 8.

[0016] The second lifting platform 2 is provided with adjusting bolts 3 on both sides. The top of the adjusting bolts 3 is engaged with the bottom of the first lifting platform 1, and a silicone pad is provided on the top of the adjusting bolts 3. The first lifting platform 1 is a cylindrical box with an open top, and an observation window made of acrylic sheet is provided on the side of the first lifting platform 1.

[0017] like Figure 2 As shown, the buffer assembly 4 includes a fixed frame 41. Connecting blocks 42 are slidably mounted on both sides of the interior of the fixed frame 41. The two connecting blocks 42 are connected and fixed together by a damper 43. A spring 44 is fitted onto the outer side of the damper 43. Both ends of the spring 44 are fixed to the two connecting blocks 42 respectively. Rotating rods 45 are rotatably connected to the two connecting blocks 42 respectively. The other end of the rotating rod 45 is rotatably connected to a slider 46. The slider 46 is slidably disposed in a mounting groove inside a mounting block 47. The mounting block 47 is fixedly installed inside the connecting frame 10. To ensure low cost and structural simplicity, the buffer assembly can also be replaced with a thick silicone pad. The silicone pad is fixed to the lower part of the connecting frame 10 and cooperates with the guide rod 9.

[0018] like Figure 3 As shown, the lifting assembly 6 includes a lifting box 61. A guide frame 69 is installed on the top inner side of the lifting box 61. A lifting rod 68 is slidably installed in the guide frame 69. A through hole is provided on the top of the lifting box 61 corresponding to the lifting rod 68. There is an movable gap between the through hole and the lifting rod 68. The top of the lifting rod 68 extends out of the through hole and connects to the connecting frame 10. A threaded rod 62 is rotatably connected to the lifting box 61 below the guide frame 69. A limit block 66 is provided in the middle of the threaded rod 62. The threads of the threaded rod 62 on both sides of the limit block 66 have opposite directions and are respectively equipped with an adjusting block 63. The adjusting block 63 is threadedly connected to the threaded rod 62 and can maintain lateral movement. The two adjusting blocks 63 are respectively connected to the lifting rod 68 through the connecting rod 67. A stabilizing block 64 is fixed at the bottom of the two adjusting blocks 63. The stabilizing block 64 is slidably connected to the slide groove 65 provided on the bottom inner side of the lifting box 61. The telescopic support leg 7 is connected to the bottom outer side of the lifting box 61. One end of the threaded rod 62 extends out of the lifting box 61 and is connected to the handwheel assembly 5.

[0019] like Figure 4 As shown, the handwheel assembly 5 includes a turntable 51, a handle 52, and a fixing bolt 53. The turntable 51 is fixedly connected to the threaded rod 62. The handle 52 is fixed on the side of the turntable 51 away from the lifting box 61, and the fixing bolt 53 is provided on the turntable 51 on the side opposite to the handle 52.

[0020] The working principle and usage process of this utility model: In use, extend the telescopic support leg 7 and secure it stably under the transformer respirator. Adjust the length of the telescopic support leg 7 to bring the overall height of the equipment close to the respirator. Then, turn the handle 52 clockwise to rotate the turntable 51, which in turn rotates the threaded rod 62. As the threaded rod 62 rotates, it moves the two adjusting blocks 63 towards the limiting block 66, causing the connecting rod 67 to move the lifting rod 68 upward, raising the first lifting platform 1 and the second lifting platform 2 to just support the respirator. Turn the fixing bolt 53 to fix the turntable 51 and the lifting box 61. Then, adjust the adjusting bolt 3 so that the silicone pad at the top of the adjusting bolt 3 is in contact with the bottom of the first lifting platform 1. After fixing, remove the fixing screws of the respirator and slowly lift the glass cover to allow the waste desiccant inside the glass cover to fall into the first lifting platform 1 and be collected into the collection bag through the collection port 11. When the waste desiccant falls into the first lifting platform 1, it exerts downward pressure on the platform, causing the guide rod 9 to move downward. When the guide rod 9 contacts the fixed frame 41, it presses the frame down. The fixed frame 41 then drives the connecting block 42 and the slider 46 to slide to both sides via the rotating rod 45, causing the damper 43 and spring 44 to stretch and buffer the pressure on the first lifting platform 1. As the waste desiccant is collected, the buffer assembly slowly returns to its original position. After the waste desiccant in the glass cover is cleaned out, new desiccant is added, and the device is returned to its original position. The entire process eliminates the need to move the respirator, reducing the workload of maintenance personnel and the risk of respirator damage, and greatly improving the efficiency of respirator replacement.

[0021] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
