It belongs to the technical field of transformer maintenance tools, specifically to the technical field of connecting flanges that can be adapted to drain oil from transformers of various specifications. Background Technology

[0002] In transformer maintenance and repair, draining oil is a common procedure. Connecting flanges are used to connect the transformer's drain port to the drain pipe. However, different transformer sizes have different drain port dimensions and installation locations. Traditional fixed-size connecting flanges are difficult to adapt to various transformer sizes, leading to frequent flange replacements during draining operations. This not only reduces work efficiency but also increases operating costs and equipment management complexity. Therefore, there is an urgent need for a connecting flange that can adapt to draining oil from multiple transformer sizes to solve these problems. Utility Model Content

[0003] The purpose of this utility model is to provide a connecting flange that can be adapted to the oil draining of transformers of various specifications. It has the advantages of being adaptable to the oil draining ports of different transformer specifications, being easy to install and adjust, and improving the adaptability and efficiency of oil draining operations, thus solving the problem of poor adaptability of traditional flanges.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A connecting flange adaptable to the oil draining of transformers of various specifications includes a mounting plate, a guide pipe installed on one side of the mounting plate, guide rails installed on both sides of the mounting plate, a sliding plate slidably installed on the guide rails, a smooth surface on the other side of the mounting plate, and a pressure plate provided on the outside of the other side of the mounting plate. The pressure plate and the sliding plate are connected by an adjusting rod.

[0006] As a preferred technical solution of this utility model, a through hole is provided on the mounting plate at the position corresponding to the guide tube.

[0007] As a preferred embodiment of this utility model, both the adjusting rod on the outside of the pressure plate and the adjusting rod on the outside of the sliding plate are connected by threaded bolts.

[0008] Compared with existing technologies, the advantages of this utility model are as follows: By setting up a mounting plate, guide pipe, guide rail, sliding plate, adjusting rod, and pressure plate, the guide rail allows the sliding plate to slide and adjust its position. The adjusting rod connects to the pressure plate, enabling flexible adjustment of the distance and position between the pressure plate and the sliding plate according to the size and installation requirements of different transformer drain ports, thus achieving adaptable connection for various transformer drain ports. During installation, one side of the mounting plate is aligned with the transformer drain port. By adjusting the position of the sliding plate on the guide rail, the adjusting rod moves the pressure plate to match the surrounding structure of the transformer drain port. Finally, the fixing bolts are tightened to complete the installation, making the operation simple. This effectively solves the problem of poor compatibility of traditional connecting flanges, improves the compatibility and efficiency of flange connections in transformer draining operations, and reduces the cost caused by frequent flange replacements.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figure 1-2 This utility model provides a technical solution:

[0014] A connecting flange adaptable to various transformer specifications for oil draining includes a mounting plate 1: serving as the basic load-bearing component, it is made of high-strength, corrosion-resistant metal materials such as stainless steel, possessing good structural strength and sealing performance. One side is used to fit against the transformer oil drain port, ensuring a smooth surface; processing techniques such as grinding and polishing are used to ensure flatness and improve the sealing fit with the oil drain port; the other side is used to install other functional components.

[0015] Guide pipe 2: Installed on one side of mounting plate 1, it communicates with the through hole 9 on mounting plate 1. Oil can flow into guide pipe 2 through transformer drain port and through hole 9, and then be introduced into the drain pipeline. The diameter of guide pipe 2 can be designed according to the common transformer drain flow requirements, and it also has a certain degree of versatility to adapt to different drain rate scenarios.

[0016] Guide rail 3: Symmetrically installed on the mounting plates 1 on both sides of the guide tube 2, using a sliding rail and slider cooperation structure or other linear sliding adapter structure to provide sliding guidance for the sliding plate 4, ensuring that the sliding plate 4 moves smoothly and steadily, and can withstand a certain clamping force to ensure the structural stability after connection.

[0017] Sliding plate 4: Slidingly mounted on guide rail 3, it can slide freely along the length of guide rail 3. Its position can be adjusted to adapt to the installation space around the oil drain port of different transformers, providing an installation foundation and adjustment support for pressure plate 6.

[0018] Adjusting rod 5: As a connecting and adjusting component, its two ends are connected to pressure plate 6 and sliding plate 4 respectively. The adjusting rod 5 can be made of screw structure with threads machined on its surface, and can be matched with the appropriate connecting structures on pressure plate 6 and sliding plate 4, such as threaded holes, through holes with nuts, etc. By changing the length of the adjusting rod 5 between pressure plate 6 and sliding plate 4, the distance between pressure plate 6 and mounting plate 1 can be adjusted to adapt to transformer oil drain port structures of different thicknesses and installation forms.

[0019] Pressure plate 6: Located on the other side of the mounting plate 1, it is connected to the adjusting rod 5. Through contact and compression with the surrounding structures of the transformer drain port, such as the transformer housing and flange seat, it works in conjunction with the mounting plate 1 to fix and clamp the connecting flange to the transformer drain port. Pressure plate 6 needs to have a certain structural strength and adaptability. It can be designed as a flat plate with a surface treated for anti-slip and anti-corrosion properties.

[0020] Fixing bolt 7: Installed on the adjusting rod 5 on the outside of the pressure plate 6 and the adjusting rod 5 on the outside of the sliding plate 4 via threaded connection. After the sliding plate 4 and the pressure plate 6 are adjusted to their positions, tighten the fixing bolt 7 to fix the position of the sliding plate 4 and the pressure plate 6 using the threaded locking force, ensuring a stable connection between the connecting flange and the transformer oil drain port, and preventing displacement due to oil flow, external forces, or other factors.

[0021] Through hole 9: It is opened on the mounting plate 1 at the position corresponding to the guide pipe 2, and serves as a channel for oil to flow from the transformer drain port into the guide pipe 2. Its diameter needs to be compatible with the inner diameter of the guide pipe 2. At the same time, it should be compatible with common transformer drain ports. It can be designed as a circular through hole with a diameter that is universal within a certain range, such as determined according to the common drain port size range in the industry.

[0022] Working principle

[0023] When performing transformer oil draining operations, first, place the smooth side of mounting plate 1 against the surface of the transformer oil drain port, aligning the through hole 9 with the oil drain port. Then, adjust the position of sliding plate 4, which is mounted on guide rail 3, on mounting plate 1 according to the surrounding space and installation structure of the transformer oil drain port. Next, adjust the distance between pressure plate 6 and mounting plate 1 using adjusting rod 5, ensuring pressure plate 6 fits snugly against the adaptable structure around the transformer oil drain port, such as protrusions on the transformer housing or reserved mounting surfaces. After adjusting the positions of sliding plate 4 and pressure plate 6 to the appropriate positions, tighten the fixing bolts 7 at both ends of adjusting rod 5. Using the locking force of the fixing bolts 7, fix sliding plate 4 to guide rail 3, simultaneously pressing pressure plate 6 tightly against the surrounding structure of the transformer oil drain port, thus achieving a stable and sealed connection between the connecting flange and the transformer oil drain port. At this point, the oil inside the transformer can flow into guide pipe 2 through the oil drain port and through hole 9, and then be discharged through the oil drain pipeline connected to guide pipe 2, completing the oil draining operation.

[0024] When it is necessary to adapt to transformers of different specifications, simply repeat the above adjustment steps, namely sliding the sliding plate 4, adjusting the length of the adjusting rod 5, and tightening the fixing bolts 7, to quickly complete the adaptation connection between the connecting flange and the oil drain port of the new specification transformer without replacing the flange body.

[0025] When using:

[0026] At the transformer oil draining site, maintenance personnel first clean debris from the surface of the drain port and check its integrity. Then, they align the smooth side of the mounting plate 1 of the connecting flange with the drain port, ensuring the through-hole 9 is aligned. Next, based on the surrounding structure of the drain port, the sliding plate 4 is slid to the appropriate position via visual inspection and simple measurement. The spacing of the pressure plates 6 is adjusted using the adjusting rod 5, ensuring the pressure plates 6 conform to the surrounding structure of the drain port, such as the tank surface. Afterward, the fixing bolts 7 on the outer sides of the pressure plates 6 and the sliding plate 4 are tightened sequentially, pre-tightening first and then gradually tightening to ensure even force on both sides. Finally, the guide pipe 2 is connected to the drain pipeline, and the connection's firmness and sealing are checked. Once everything is confirmed to be correct, the oil draining process is initiated. During the process, the connecting flange is monitored in real time for leaks, loosening, or other abnormalities; any issues are addressed promptly.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
