Description

Technical Field

[0001] This utility model belongs to the field of transformer cleaning, and in particular relates to an anti-sway device used when cleaning transformer heat sinks with high-pressure water. Background Technology

[0002] Oil-immersed transformers are equipped with plate-type heat sinks on the outside. The heat sinks are hollow plates formed by welding thin steel plates, and the plates are connected only by upper and lower oil collection pipes, resulting in relatively weak overall rigidity. During the daily operation and maintenance of the transformer, it is necessary to regularly use high-pressure water to wash and clean the surface of the heat sinks to remove dust, oil, and debris.

[0003] When high-pressure water flows onto the surface of a heat sink, it generates a large impact force, which can easily cause the heat sink to shake and shift back and forth. Long-term repeated shaking can not only cause fatigue cracking of the weld connecting the heat sink and the oil collection pipe, leading to leakage of insulating oil, but also exacerbate the deformation of the heat sink body and misalignment of the spacing between the fins, thus affecting the normal heat dissipation effect. Utility Model Content

[0004] The purpose of this invention is to provide an anti-sway device for high-pressure water cleaning of transformer heat sinks, which can buffer the impact force brought by the high-pressure water flow, effectively suppress the shaking and displacement of the heat sinks during the rinsing process, and protect the heat sinks and connecting structures.

[0005] This utility model adopts the following technical solution: an anti-sway device used for high-pressure water cleaning of transformer heat sinks, comprising: Vertical load-bearing plate, installed vertically; The upper and lower support mechanisms are horizontally arranged and opposite to each other; their left ends are fixedly connected to the vertical force-bearing plate, and their right ends extend to the right; the upper and lower support mechanisms cooperate with the vertical force-bearing plate to form a receiving area with an opening on the right side; the receiving area is used for the transformer heat sink to extend into. The clamping plate is vertically positioned, with its upper end fitted onto the right end of the upper support mechanism and its lower end fitted onto the right end of the lower support mechanism. The clamping plate is used to cooperate with the vertical support plate, the upper support mechanism, and the lower support mechanism to clamp the heat sink. Both the upper and lower load-bearing mechanisms include: The support rod has its left end fixedly connected to the vertical load-bearing plate and its right end extending to the right. The elastic element is sleeved on the support rod. Its left end is fixedly connected to the vertical force plate, and its right end extends to the right and abuts against the left side of the clamping plate. The elastic element is used to generate a deformation perpendicular to its own axis when the heat sink is flushed by the heat sink. This buffers the impact of the high-pressure water flow on the heat sink, absorbs vibration energy, and reduces the shaking of the heat sink caused by the water flow impact.

[0006] The beneficial effects of this utility model are: This invention can be directly installed on the heat sink after the transformer is shut down and the power is cut off. Then, high-pressure water is used to clean the heat sink. During the cleaning process, this invention can greatly reduce the impact of high-pressure water flow on the heat sink, absorb vibration energy and reduce the shaking of the heat sink caused by the impact of water flow. This utility model uses a vertical force plate and a clamping plate to limit the left and right movement of the heat sink, and uses an upper and lower force-bearing mechanism to support and limit the upper and lower movement of the heat sink. It constrains the displacement of the heat sink in multiple directions, thereby reducing the amount of shaking of the heat sink when flushed by high-pressure water flow from the source, and avoiding the problem of weld cracking and oil leakage at the connection between the heat sink and the oil collection pipe due to repeated shaking. The upper and lower support mechanisms of this utility model are equipped with elastic elements, which can cause the side of the elastic element to deform perpendicular to its own axis when subjected to top pressure, thereby buffering the impact of high-pressure water flow on the heat sink, absorbing vibration energy and reducing the shaking of the heat sink caused by the impact of water flow. The upper and lower force-bearing shells of this invention adopt a triangular cross-section design, which provides stable radial support while forming an outer peripheral limit on the elastic element, constraining the excessive vertical displacement of the elastic element when it is compressed, and preventing the elastic element from warping and deviating significantly.

[0009] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more. The term "orientation" in this utility model refers to the orientation of the utility model within the... Figure 1 Description of the state's progression.

[0011] This utility model discloses an anti-sway device used when high-pressure water cleaning transformer heat sinks, such as... Figure 3 and 4 As shown, it includes a vertical load-bearing plate 10, an upper load-bearing mechanism 11, a lower load-bearing mechanism 12, and a clamping plate 13.

[0012] The vertical load-bearing plate 10 is vertically set and serves as the left-side reference load-bearing base of the entire device; the upper load-bearing mechanism 11 and the lower load-bearing mechanism 12 are both horizontally arranged and positioned opposite each other vertically; the left ends of the upper load-bearing mechanism 11 and the lower load-bearing mechanism 12 are welded and fixed to the vertical load-bearing plate 10, and the right ends of the upper load-bearing mechanism 11 and the lower load-bearing mechanism 12 extend horizontally to the right. The upper load-bearing mechanism 11 and the lower load-bearing mechanism 12 cooperate with the vertical load-bearing plate 10 to form a receiving area with an opening on the right side; the receiving area is used for the transformer heat sink 20 to extend into.

[0013] The clamping plate 13 is also vertically arranged. The upper end of the clamping plate 13 is movably sleeved on the right end of the upper support mechanism 11, and the lower end of the clamping plate 13 is movably sleeved on the right end of the lower support mechanism 12. The vertical support plate 10, the upper support mechanism 11, the lower support mechanism 12, and the clamping plate 13 cooperate with each other to form a closed receiving area. The clamping plate 13 is used to cooperate with the vertical support plate 10, the upper support mechanism 11, and the lower support mechanism 12 to clamp the heat sink 20. During assembly and use, the lower end face of the upper support mechanism 11 and the upper end face of the lower support mechanism 12 abut against the upper and lower surfaces of the heat sink 20, respectively. The left side wall of the heat sink 20 abuts against the right side of the vertical support plate 10, and the right side wall of the heat sink 20 abuts against the left side of the clamping plate 13. The heat sink 20 is clamped and fixed from four directions: left, right, up, and down, which greatly reduces the shaking amplitude of the heat sink 20.

[0014] like Figure 1 and 2 As shown, the upper support mechanism 11 and the lower support mechanism 12 have the same structure, both including a support rod 14 and an elastic element 15. The left end of the support rod 14 is fixedly connected to the vertical force plate 10, and the right end of the support rod 14 extends horizontally to the right. The elastic element 15 is sleeved on the outside of the support rod 14, with its left end fixedly connected to the vertical force plate 10 and its right end extending to the right and abutting against the left side of the clamping plate 13. The elastic element 15 is used to deform perpendicular to its own axis when the heat sink 20 is flushed by the pressure of the heat sink 20, thereby buffering the impact of the high-pressure water flow on the heat sink 20, absorbing vibration energy, and reducing the shaking of the heat sink 20 caused by the water flow impact.

[0015] Preferably, the upper load-bearing mechanism 11 further includes an upper load-bearing housing 16; the upper load-bearing housing 16 has a hollow triangular cross-section and covers the outer side of the elastic element 15 of the upper load-bearing mechanism 11; an upper load-bearing groove is formed on the bottom wall of the upper load-bearing housing 16, and the side of the elastic element 15 of the upper load-bearing mechanism 11 extends downward from the upper load-bearing groove and presses against the upper side of the heat sink 20. The upper load-bearing housing 16 is used to provide peripheral restraint and radial support for the elastic element 15 installed therein. The triangular structure of the upper load-bearing housing 16 has strong structural stability, can uniformly transmit pressure, and at the same time protects the elastic element 15.

[0016] Preferably, the lower support mechanism 12 further includes a lower load-bearing housing 17; the lower load-bearing housing 17 has a hollow triangular cross-section and covers the outer side of the elastic member 15 of the lower support mechanism 12. A lower load-bearing groove 21 is provided on the bottom wall of the lower load-bearing housing 17. The side of the elastic member 15 of the lower support mechanism 12 protrudes upward from the lower load-bearing groove 21 and presses against the lower side of the heat sink 20. The lower load-bearing housing 17 is used to provide peripheral restraint and radial support for the elastic member 15 housed within it. The lower load-bearing housing 17 corresponds to the upper load-bearing housing 16 in structure and function, protecting the lower elastic member 15 while ensuring that the elastic member 15 can normally contact the heat sink 20 and play a buffering role.

[0017] The upper and lower load-bearing shells 16 and 17 are fitted onto the outer sides of the corresponding elastic elements 15, providing peripheral restraint and overall support for the elastic elements 15. During compression and buffering, the elastic elements 15 are prone to lateral expansion, displacement, and deformation instability. The upper and lower load-bearing shells 16 and 17, relying on their high-strength triangular cross-sections, can constrain and support the outer walls of the elastic elements 15, effectively limiting lateral deformation during compression and preventing tilting or twisting. The sides of the elastic elements 15 extend and partially contact the heat sink 20, ensuring that the elastic elements 15 function properly in elastic buffering, shock absorption, and force dissipation, while also ensuring uniform force distribution and long-term buffering and vibration reduction effects.

[0018] Preferably, the clamping plate 13 has guide holes at both its upper and lower ends. Guide tubes 18 are fixed to the clamping plate 13 at the corresponding guide holes. The guide tubes 18 are coaxially arranged with the corresponding elastic elements 15. The guide tubes 18 are used to guide the clamping plate 13 to slide along the support rod 14. After clamping the heat sink 20, a nut 19 is screwed onto the right end of the support rod 14. The nut 19 is used to press against the end of the guide tube 18 to lock the axial displacement of the clamping plate 13, so that the elastic element 15 is kept in a compressed state and presses against the heat sink 20.

[0019] The working principle of this utility model: When using this device, first, based on the position of the transformer heat sink 20 to be flushed, without disassembling the heat sink 20, directly move the entire device to the position of the heat sink 20, so that the heat sink 20 extends into the receiving area enclosed by the vertical force plate 10, the upper support mechanism 11, and the lower support mechanism 12, so that the left side of the heat sink 20 is against the vertical force plate 10, the upper side of the heat sink 20 abuts against the side of the elastic element 15 of the upper support mechanism 11, and the lower side of the heat sink 20 abuts against the side of the elastic element 15 of the lower support mechanism 12. Then, slide the clamping plate 13 along the support rod 14 so that the left side of the clamping plate 13 is against the right side of the heat sink 20, and then tighten the nut 19 at the end of the support rod 14 to tighten the clamping plate 13, thereby limiting the left and right and up and down directions of the heat sink 20.

[0020] High-pressure water is used to rinse the heat sink 20. When the high-pressure water flows over the heat sink 20, it will shake. Consequently, the side of the elastic element 15 will deform perpendicular to its own axis due to the pressure from the heat sink 20, thus absorbing vibration energy and reducing the shaking of the heat sink 20 caused by the water flow. After rinsing, loosen the nut 19 and remove the clamping plate 13 to remove the device from the heat sink 20. The operation is convenient.

[0021] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
