Description

Technical Field

[0001] This utility model relates to the field of transformer technology, specifically to a support structure and a power transformer. Background Technology

[0002] For safety, heat dissipation, and space layout reasons, power transformers are often installed high on utility poles, and the support structure plays a crucial role in securing them. However, traditional single-layer clamp supports have significant drawbacks.

[0003] Outdoor utility poles are mostly made of concrete and are exposed to the elements for extended periods. Their surfaces easily accumulate large amounts of fly ash, significantly reducing the friction between the clamps and the pole. Under gravity, the transformer and its support structure are at risk of falling. Furthermore, during natural disasters such as strong winds and earthquakes, relative displacement can occur between the pole and the clamp fixing mechanism. Frequent shaking and pulling can cause fatigue damage to the clamps. Over time, the clamps' fastening performance decreases, potentially leading to the transformer falling. This not only damages power facilities but also seriously threatens the safety of nearby people and property. Utility Model Content

[0004] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a support structure and a power transformer to overcome the deficiency in existing support structures regarding the lack of safety features in dealing with the risk of falling.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: On the one hand, the present invention provides a support structure, including: a first clamp on the support body, the first clamp being fixed to a utility pole, a second clamp below the first clamp, a clamping rod rotatably disposed on the second clamp, one end of the clamping rod being rotatably connected to the first clamp, and the other end being fixed to a clamping plate; wherein, the clamping rod forms a first rotation position and a second rotation position with the first clamp and the second clamp respectively, and the clamping plates together form a clamping area.

[0006] Optionally, the bracket body includes two symmetrically arranged first brackets, forming a fixed area between the two first brackets. The first clamp is fixed to both ends of the fixed area by screws, and the two first brackets are connected and fixed by a plurality of second brackets.

[0007] Optionally, the clamping rod has a second rod portion, and a first rod portion and a third rod portion located at both ends of the second rod portion, respectively. The first rod portion is located at the end of the second rod portion near the first clamp, and a movable groove is provided on the first rod portion.

[0008] Optionally, a plurality of pressure rods are fixed on the side of the first clamp near the second clamp, and the pressure rods are rotatably connected in the movable groove to form a first rotation position.

[0009] Optionally, the movable groove is elliptical.

[0010] Optionally, a plurality of fixing plates are fixed to the outer periphery of the second clamp, and the fixing plates are rotatably connected to the second rod portion to form a second rotation position.

[0011] Optionally, the third rod and the clamping plate are fixedly connected.

[0012] Optionally, the clamping plate is tightly pressed against the outer surface of the utility pole to form the clamping area, and the clamping area becomes smaller when the first clamp moves toward the second clamp.

[0013] Optionally, the clamping plate may also be provided with a number of spikes on its surface.

[0014] On the other hand, this utility model also provides a power transformer, including a transformer body, which is fixed on the support body.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention features a second clamp and a rotating rod below the first clamp. The rotating rod forms a first rotating position and a second rotating position with both the first and second clamps. When the first clamp moves closer to the second clamp due to pressure, the first rotating position moves, causing the rotating rod to rotate around the second rotating position. This reduces the clamping area formed by the clamping plates and ensures tight contact with the outer perimeter of the utility pole, preventing the first clamp, its support structure, and the power transformer from further descent. This invention provides a safety measure through the above method, effectively mitigating the risk of the power transformer falling due to decreased fastening performance.

[0017] In addition, the present invention is provided with several spikes on the clamping plate. When the clamping area becomes smaller, the clamping plate moves toward the utility pole. The small contact area of ​​the spikes brings a large pressure, thereby piercing the spikes into the utility pole to prevent it from falling. This further improves the anti-falling effect of the bracket and power transformer of the present invention. Attached Figure Description

[0027] 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.

[0028] As mentioned earlier, existing technologies typically use a single-layer clamp to secure power transformers and their support structures. However, outdoor utility poles are mostly made of concrete and are exposed to the elements for extended periods. Their surfaces are prone to accumulating large amounts of fly ash, significantly reducing the friction between the clamp and the pole. Under gravity, the transformer and its support structure are at risk of falling. Furthermore, during natural disasters such as strong winds and earthquakes, relative displacement can occur between the pole and the clamp fixing mechanism. Frequent shaking and pulling can cause fatigue damage to the clamp. Over time, the clamp's fastening performance decreases, potentially leading to the transformer falling. This would not only damage power facilities but also seriously threaten the safety of surrounding personnel and property.

[0029] Therefore, this utility model provides a support structure and a power transformer, offering a safety measure to prevent the clamps from falling off the utility pole, thus solving the aforementioned problems. This utility model solves the problem in the following way.

[0030] Example 1:

[0031] Please refer to the instruction manual appendix. Figures 1 to 5 As shown in the figure, this embodiment provides a support structure, which includes a support body 1, a first clamp 2, a second clamp 3, a clamping rod 4, and a clamping plate 5. The support body 1 includes two symmetrically arranged first supports 11, which are parallel and symmetrically arranged together to form a fixed area. The first clamp 2 is fixed to both ends of this fixed area by screws, and the two first supports 11 are connected and fixed together by several second supports 12.

[0032] Simultaneously, the first clamp 2 is fitted and fixed to the utility pole, and the second clamp 3 is similarly fitted and fixed to the utility pole. The second clamp 3 is located below the first clamp 2 (on the side closer to the ground). Multiple clamping rods 4 are provided, evenly distributed around the second clamp 3, and rotatably connected to the second clamp 3, thus forming a second rotating position. One end of the clamping rod 4 is also rotatably connected to the first clamp 2, forming a first rotating position; the other end is connected to the clamping plate 5. The surface of the clamping plate 5 (the side closer to the utility pole) is tightly fitted to the utility pole, and all the clamping plates 5 together form a clamping area. When the first clamp 2 moves downward (towards the second clamp 3), it will cause the clamping rod 4 to rotate around the second rotating position, thereby bringing all the clamping plates 5 closer together, i.e., reducing the clamping area, making the clamping plates 5 clamp the utility pole more tightly. At the same time, the reaction force of the utility pole on the clamping plate 5 also causes the clamping rod 4 to stop rotating, thereby stopping the first clamp 2 from moving downward, and finally achieving the effect of preventing it from falling.

[0033] In this first embodiment, as Figure 3As shown, the clamping rod 4 has a second rod portion 42, and a first rod portion 41 and a third rod portion 43 located at opposite ends of the second rod portion 42. The first rod portion 41 is located at the end of the second rod portion 42 near the first clamp 2, and an elliptical movable groove 411 is formed on the first rod portion 41. Several pressure rods 21 are fixed on the bottom surface of the first clamp 2 (the side near the second clamp 3), and the pressure rods 21 are rotatably connected to the movable groove 411 via a rotating shaft, forming a first rotating position. Several fixing plates 31 are fixed on the outer periphery of the second clamp 3, and the fixing plates 31 are also rotatably connected to the second rod portion 42 via a rotating shaft, forming a second rotating position. The third rod portion 43 is fixedly connected to the clamping plate 5.

[0034] Therefore, in the specific implementation of this embodiment, when the support body 1 and the power transformer on it fall downwards, the first clamp 2 moves downwards synchronously, and drives the pressure rod 21 to move as follows. Figure 5 As shown by the dotted line a, the movement occurs simultaneously with the rotating shaft on the pressure rod 21 moving within the movable groove 411 and abutting against the pressing clamping rod 4, causing it to rotate around the second rotation position (that is, the center of rotation where the rotating shaft connecting the fixed plates 31 of the second rod part 42 is located). Then the first rod part 41 will form as shown... Figure 5 When the direction of the dotted line b is rotated, the third rod 43 and the clamping plate 5 will form as shown. Figure 5 The direction of the dotted line c is shifted, thus creating a horizontal displacement difference in the clamping plate 5. This displacement difference reduces the clamping area, resulting in a tighter contact with the surface of the utility pole. Simultaneously, the utility pole exerts a counter-pushing force on the clamping plate 5. This counter-pushing force, acting on the first clamp 2, prevents the first clamp 2 from descending, ultimately preventing the support structure and power transformer from falling. This achieves the effect of preventing it from falling.

[0035] Example 2:

[0036] Based on the above embodiments, in order to further clarify and completely explain the technical solutions therein, this utility model also provides an embodiment two. In this embodiment two, as... Figure 6 As shown, the clamping plate 5 is also provided with several spikes 51 on its surface. When the clamping plates 5 come close to each other (as detailed in Embodiment 1), the spikes 51 will tightly abut against the outer surface of the utility pole. Due to the small contact area and high contact pressure between the spikes 51 and the outer surface of the utility pole, a great pressure will be generated, eventually driving the spikes 51 into the utility pole (completely or partially), thereby achieving the effect of preventing them from falling.

[0037] Example 3:

[0038] Based on the same general inventive concept, this utility model also provides a power transformer, including a transformer body, which is fixed on the aforementioned support body 1.

[0039] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
