Description

Technical Field

[0001] This application relates to the field of transformer technology, and in particular to a transformer mounting structure and a transformer mounting bracket. Background Technology

[0002] Transformers are fundamental and critical equipment in power systems. They can step up or step down the input voltage to meet the voltage requirements of end-user electrical equipment.

[0003] Transformers are typically installed on utility poles, which can be single or double poles. Regardless of the pole type, a mounting bracket needs to be installed on the pole before the transformer is mounted on the bracket. For example, invention patent CN116453811A discloses a bracket for transformer installation. This bracket uses a fixing component to initially secure the bracket, and then utilizes the weight of the transformer to drive a connecting component to apply pressure to the pole, thereby providing a secondary fixation to the bracket and improving its installation stability.

[0004] However, in the aforementioned patent, after the transformer is installed on the mounting plate, the rotating arm in the connecting assembly will rotate and its end will abut against the pole. At this time, the magnitude of the force between the transformer and the pole depends entirely on the pressure of the transformer on the rotating arm. This places high demands on the strength of the rotating arm, and its working stability will be greatly reduced after being subjected to high pressure for a long time, which brings a great burden to the later maintenance. Summary of the Invention

[0005] This application provides a transformer mounting structure and a transformer mounting bracket to solve the problems in the prior art.

[0006] On one hand, embodiments of this application provide a transformer mounting structure, including:

[0007] A clamp is a ring-shaped structure used to fit around the outer surface of a utility pole.

[0008] The pressure rod is vertically and movably inserted into the clamp, with the lower end of the pressure rod inserted into the clamp. When the pressure rod is pressed down by the transformer, it moves downward.

[0009] The rotating rod is rotatably installed inside the clamp. The upper end of the rotating rod is movably connected to the lower end of the pressure rod, and the lower end of the rotating rod extends out from the bottom of the clamp.

[0010] The extrusion section is located at the lower end of the rotating rod. When the lower end of the rotating rod rotates upward under the drive of the pressure rod, the extrusion section is inserted between the pole and the clamp.

[0011] On the other hand, this application embodiment also provides a transformer mounting bracket, including a mounting plate, a base plate, and the above-mentioned transformer mounting structure. The transformer mounting structure is disposed on the side of the base plate, the mounting plate is located above the base plate, and the upper end of the pressure rod in the transformer mounting structure is connected to the mounting plate.

[0012] The transformer mounting structure and transformer mounting bracket disclosed in this application have the following advantages:

[0013] After the transformer is installed, the clamping part will be inserted from below between the clamp and the pole under the downward pressure of the transformer. This not only ensures the installation stability of the clamp, but also has very low requirements for the strength and stability of the clamping rod and the rotating rod, greatly reducing maintenance costs.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Figure 1-3 This is a schematic diagram of a transformer mounting structure provided in an embodiment of this application. This application provides a transformer mounting structure, including:

[0022] The clamp 100 is a ring-shaped structure and is used to be fitted onto the outer surface of the pole.

[0023] The pressure rod 200 is vertically and movably inserted into the clamp 100. The lower end of the pressure rod 200 is inserted into the clamp 100. When the pressure rod 200 is pressed down by the transformer, it moves downward.

[0024] The rotating rod 220 is rotatably installed inside the clamp 100. The upper end of the rotating rod 220 is movably connected to the lower end of the pressure rod 200, and the lower end of the rotating rod 220 extends out from the bottom of the clamp 100.

[0025] The extrusion part 230 is provided at the lower end of the rotating rod 220. When the lower end of the rotating rod 220 rotates upward under the drive of the pressure rod 200, the extrusion part 230 is inserted between the pole and the clamp 100.

[0026] For example, the clamp 100 has a hollow structure inside, and openings can be provided on its top and bottom surfaces to allow the pressure rod 200 and the rotating rod 220 to pass through, respectively. Since both the pressure rod 200 and the rotating rod 220 need to bear the weight of the transformer, the structural strength requirements are relatively high. In practice, alloys, such as aluminum alloys or steel, can be used to make them, while the extrusion part 230 can be made of rubber.

[0027] During installation, the clamp 100 is first installed on the pole, and then the transformer is placed on the pressure rod 200. As the transformer presses down, the pressure rod 200 gradually inserts into the clamp 100, causing the rotating rod 220 to rotate. The pressing part 230 at the lower end of the rotating rod 220 gradually rises with the rotation of the rotating rod 220 and eventually inserts between the inner side of the pole and the clamp 100. Since the connection between the clamp 100 and the pole is not very tight and there is usually a certain gap, inserting the pressing part 230 as a filling structure can greatly improve the tightness of the connection between the clamp 100 and the pole. Moreover, after the pressing part 230 is inserted from below, the clamp 100, under the weight of the transformer, will ensure that the pressing part 230 is tightly placed in the gap between itself and the pole, and the stability of this insertion will increase with the increase of the transformer's downward pressure. Even if the force provided by the rotating rod 220 is removed after the extrusion part 230 is inserted, the stability of the extrusion part 230 insertion will not be affected. Therefore, the structural strength requirements of the pressure rod 200 and the rotating rod 220 are not high in this application, and their reliability will not be reduced after long-term use, which greatly reduces the maintenance cost.

[0028] In the embodiments of this application, in order to facilitate the mounting of the clamp 100 on the utility pole, the clamp 100 is configured as an openable and closable structure. Specifically, the clamp 100 includes two sub-clamps, which are rotatably connected by a pin 120. Each sub-clamp has a locking part 110 at its end, which is used to fix the two sub-clamps together.

[0029] The sub-clamp 100 can adopt a semi-circular ring structure. The opposite ends of the two sub-clamps are rotatably connected by a pin 120, and the other opposite ends are respectively provided with locking parts 110. The locking parts 110 can be provided with through holes for bolts to pass through. After the clamp 100 is fitted onto the pole, the two sub-clamps are fixed together by passing bolts through the locking parts 110, thus initially fixing the clamp 100 to the pole. After the weight of the transformer is applied to the pressure rod 200, the pressing part 230 will be inserted between the clamp 100 and the pole, thereby achieving secondary fixation of the clamp 100.

[0030] Furthermore, the bottom of the inner side of the clamp 100 is sloped, and the wedge-shaped structure of the pressing part 230 is inserted between the pole and the sloped surface of the clamp 100 after the rotating rod 220 rotates upward. With the combination of the sloped surface and the wedge-shaped structure, when the clamp 100 is subjected to the heavy pressure of the transformer and has a tendency to slide down, the pressing part 230 will be subjected to pressure towards the pole under this downward trend. This pressure will increase the friction between the pressing part 230 and the pole, thereby providing sufficient support to the clamp 100 and ensuring that the clamp 100 will not slide down on the pole.

[0031] In one possible embodiment, the inner side of the clamp 100 is provided with a friction part 130.

[0032] For example, the friction part 130 can be made of rubber to increase the friction between the clamp 100 and the pole, and the friction part 130 can be continuously distributed on the entire inner side of the clamp 100, or it can be arranged in a dotted or block-like manner on the inner side of the clamp 100.

[0033] In the embodiments of this application, the pressing part 230, after being inserted between the inclined surfaces of the pole and the clamp 100, is higher than the friction part 130. Since there is a certain gap between the friction part 130 and the pole, after the upper end of the pressing part 230 is inserted into this gap, it is necessary to ensure that the side of the pressing part 230 closest to the pole is slightly higher than the friction part 130 so that the pressing part 230 can fill the gap. It should be understood that the height difference between the friction part 130 and the pressing part 230 should not be too large, typically needing to be controlled within 1 mm; otherwise, the pressing part 230 may not be able to be inserted.

[0034] In one possible embodiment, the lower end of the pressure rod 200 is provided with a sliding hole 210, and the upper end of the rotating rod 220 is provided with a sliding rod, which is slidably inserted into the sliding hole 210.

[0035] For example, a pivot can be provided near the center of the rotating rod 220, which can be driven to be inserted into the inner side of the clamp 100 so that the rotating rod 220 can rotate inside the clamp 100.

[0036] Furthermore, a torsion spring can be installed on the shaft of the rotating rod 220. This torsion spring can provide an upward rotational force for the upper end of the rotating rod 220. Under the action of this force, the lower end of the rotating rod 220 will be at its lowest position in its natural state. At this time, the pressing part 230 is away from the bottom of the clamp 100 and will not obstruct the clamp 100 from being fitted onto the pole. The secondary fixing operation will only be performed after the clamp 100 is fitted onto the pole.

[0037] like Figure 4 As shown in the figure, this application embodiment also provides a transformer mounting bracket, which includes a mounting plate 300, a base plate 400 and the above-mentioned transformer mounting structure. The transformer mounting structure is disposed on the side of the base plate 400, the mounting plate 300 is located above the base plate 400, and the upper end of the pressure rod 200 in the transformer mounting structure is connected to the mounting plate 300.

[0038] For example, the mounting plate 300 needs to be slightly larger than the base plate 400 so that the pressure bar 200 can be connected to the bottom surface of the mounting plate 300, but the size should not be too large to avoid affecting the passage of the pole through the clamp 100.

[0039] In the embodiments of this application, the distance between the mounting plate 300 and the base plate 400 in their natural state, i.e. the length of the pressure rod 200, can be appropriately adjusted so that the pressing part 230 is fully inserted into the gap between the pole and the clamp 100 and the mounting plate 300 and the base plate 400 come into contact, so that the weight of the transformer is fully applied to the base plate 400 and then transmitted to the pole through the clamp 100, avoiding applying pressure to the pressure rod 200 and the rotating rod 220 for a long time.

[0040] Furthermore, the mounting plate 300 is provided with mounting holes 310 for mounting transformers.

Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
