Description

Technical Field

[0001] This invention belongs to the field of transformer technology, specifically relating to an anti-theft and noise-reducing transformer. Background Technology

[0002] Transformers are a crucial component of the power equipment industry, widely used in urban power distribution networks, residential communities, and public power supply systems. To ensure theft prevention and noise reduction, current designs often employ comprehensive, high-strength sealing of the transformer casing, resulting in minimal gaps between the casing's joints and numerous layers of gaskets. While this enhances protection, it also severely restricts the natural convection and radiation heat dissipation within the casing. Prolonged operation can lead to excessive internal temperature rise, accelerating insulation aging, reducing equipment lifespan, and even causing discharge or burnout accidents. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide an anti-theft and noise-reducing transformer that can improve the heat dissipation efficiency of the transformer and extend its service life.

[0004] To achieve the above objectives, the present invention provides the following technical solution: This invention discloses an anti-theft and noise-reducing transformer, comprising an air inlet duct, a transformer housing, and a sealing plate. The transformer housing is rotatably mounted on the lower side panel of the air inlet duct, and the sealing plate is fixedly mounted on the upper side panel of the air inlet duct to close the upper opening of the transformer housing. Several rectangular windows are provided on the side wall of the transformer housing, and heat-conducting blades are installed within each rectangular window. The heat-conducting blades are straight and rotatably connected to the transformer housing via a hollow shaft at their center. A torsion reset device is installed between the heat-conducting blades and the transformer housing. The width of the heat-conducting blades is approximately equal to the width of the rectangular windows, and both ends of the heat-conducting blades extend from both ends of the rectangular windows. Under the prestress of the torsion reset device, the heat-conducting blades can close the rectangular windows. A cylindrical frame is fixed to the inner side of the sealing plate. The airflow from the air inlet duct acts on the heat-conducting blades and drives them to deflect. The cylindrical frame contacts the inner end of the heat-conducting blades to limit their movement.

[0005] Furthermore, a cavity is formed inside the transformer casing, which is filled with coolant. An inlet pipe and an outlet pipe are connected to the outside of the transformer casing, respectively. The inlet pipe and the outlet pipe are connected to the cavity and a water pump. The water pump is fixed at the bottom center of the transformer casing, and a cooler is installed on the inlet pipe.

[0006] Furthermore, the heat-conducting blade includes an outer main blade, an inner main blade, and a flexible connecting tube. The flexible connecting tube has elastic restoring force. The inner main blades are evenly spaced on the inner side of the outer main blades along the length direction of the heat-conducting blade. The outer main blades and each inner main blade are connected by the flexible connecting tube. The inner main blades are made of magnetic heat-conducting material, and the cylindrical frame is made of a material that is magnetically connected to the inner main blades.

[0007] Furthermore, the flexible connecting tube is coiled in a serpentine shape, with both ends of the flexible connecting tube connected to the hollow shaft. The hollow shaft is rotatably sealed with the through hole opened on the rectangular window. The hollow shaft is connected to the cavity, and the flexible connecting tube is fixedly installed in the channel opened inside the outer main blade and the inner main blade.

[0008] Furthermore, several opening slots are evenly spaced along the width direction of the heat-conducting blades on the outer main blade. The arrangement spacing of the opening slots corresponds to the arrangement spacing of the serpentine flexible connecting pipe, and the opening slots are staggered within the intervals of the flexible connecting pipe.

[0009] Furthermore, the cylindrical frame includes several rings evenly spaced along the axial direction of the transformer housing, and connecting rods for connecting the rings. The connecting rods are parallel to the axis of the transformer housing and are fixed inside the rings. The cylindrical frame is fixedly connected to the sealing plate by support rods.

[0010] Furthermore, a groove is provided on the upper side of the heat-conducting blade, and the torsion reset device includes a reset torsion spring installed in the groove. The reset torsion spring is sleeved on the outside of the hollow shaft, and the outer end of the reset torsion spring is connected to the transformer housing.

[0011] Furthermore, a rotating ring plate is fixed on the outer side of the transformer housing. A limiting groove is opened on the outer edge of the rotating ring plate. The limiting groove is used to limit the transformer housing in the axial direction. The rotating ring plate is rotatably installed in the rotating groove opened on the lower side panel of the air inlet pipe.

[0012] Furthermore, the outer side of the transformer housing is integrally formed with several protrusions. The protrusions protrude outward from the outer surface of the transformer housing and extend along the axial direction of the transformer housing. The inner side of the protrusions forms a prismatic cavity that communicates with the cavity body.

[0013] The beneficial effects of this invention are as follows: This invention discloses an anti-theft and noise-reducing transformer with significantly improved dynamic heat dissipation adjustment capabilities. It can automatically adjust the deflection angle of the heat-conducting blades according to the wind force in the air inlet duct; the stronger the wind, the greater the deflection angle of the heat-conducting blades, and the greater the heat dissipation area, thus achieving adaptive heat dissipation. Driven by wind, the heat-conducting blades unfold, forming a highly efficient airflow channel. This dual protection mechanism extends the transformer's service life and improves heat dissipation efficiency based on wind conditions.

[0014] When the transformer load is low and the heat generation is small, the heat-conducting blades tend to close under the action of the torsion reset device, reducing the risk of external dust, moisture and other contaminants entering the transformer.

[0015] Other advantages, objectives, and features of the invention will be set forth in the following description and will be apparent to those skilled in the art in some respects, or may be learned by practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

[0018] like Figures 1-9 As shown, the present invention discloses an anti-theft and noise reduction transformer, including an air inlet pipe 1, a transformer housing 2 and a sealing plate 3. The air inlet pipe 1 is used to receive air entering from the outside, and the air flow can act on the surface of the transformer.

[0019] Specifically, the transformer housing 2 is rotatably mounted on the lower side panel of the air inlet duct 1, and the sealing plate 3 is fixedly mounted on the upper side panel of the air inlet duct 1 to close the upper opening of the transformer housing 2. Several rectangular windows 4 are provided on the side wall of the transformer housing 2, extending along the axial direction of the transformer. Heat-conducting blades 5 are installed inside the rectangular windows 4. The heat-conducting blades 5 are straight and rotatably connected to the transformer housing 2 via a hollow shaft 6. A torsion reset device 7 is installed between the heat-conducting blades 5 and the transformer housing 2. The torsion reset device 7 provides elastic prestress to the heat-conducting blades 5. When there is no wind, the heat-conducting blades 5 can tilt to close the rectangular windows 4. The more the heat-conducting blades 5 deflect under wind, the more the rectangular windows 4 are opened.

[0020] The width of the heat-conducting blade 5 is similar to the width of the rectangular window 4, and the two ends of the heat-conducting blade 5 extend from the two ends of the rectangular window 4 respectively; a cylindrical frame 8 is fixed on the inner side of the sealing plate 3, and the air in the air inlet pipe 1 can act on the heat-conducting blade 5 and drive it to deflect. The cylindrical frame 8 contacts the inner end of the heat-conducting blade 5 to limit the inner end of the heat-conducting blade 5.

[0021] This invention utilizes a cylindrical frame 8 to limit the movement of the heat-conducting blades 5 under wind force, ensuring a controllable deflection range and preventing excessive oscillation that could damage the structure. After deflection, the heat-conducting blades 5 can directly contact the cylindrical frame 8 over a large area. This surface-to-surface contact increases heat transfer, thus improving heat dissipation performance without increasing the volume.

[0022] Meanwhile, the transformer housing 2 and the air inlet pipe 1 are rotatably connected, and the sealing plate 3 is fixed on the upper side, making the overall structure easy to disassemble and assemble. The torsion reset device 7 of the heat-conducting blades 5 adopts a standardized design, which is convenient for replacement or maintenance. This modular design reduces the difficulty of manufacturing and maintenance, and is suitable for large-scale production applications.

[0023] In this embodiment, a cavity 9 is formed inside the transformer housing 2, and the cavity 9 is filled with coolant. An inlet pipe 10 and an outlet pipe 11 are connected to the outside of the transformer housing 2, respectively. The inlet pipe 10 and the outlet pipe 11 are connected to the cavity 9 and are connected to a water pump 12. The water pump 12 is fixed at the bottom center of the transformer housing 2. A cooler 13 is installed on the inlet pipe 10. Liquid cooling and air cooling work together to significantly improve heat dissipation efficiency. Traditional transformer cooling usually relies solely on air cooling or liquid cooling. This invention combines the air cooling of the heat-conducting blades 5 with the liquid cooling of the coolant to form a composite heat dissipation system, avoiding the risk of overheating. The coolant cavity 9 and the heat-conducting blades 5 are linked to enhance the heat dissipation effect. Since the hollow shaft 6 of the heat-conducting blades 5 is connected to the cavity 9, the heat from the coolant can be quickly dissipated into the air through the heat-conducting blades 5. This heat exchange method fully utilizes the high heat capacity of the liquid and the fluidity of the air, allowing heat to be efficiently removed through multiple pathways, further reducing the transformer temperature rise.

[0024] In this embodiment, the heat-conducting blade 5 includes an outer main blade 14, an inner main blade 15, and a flexible connecting tube 16. The flexible connecting tube 16 has elastic restoring force. The inner main blades 15 are evenly spaced along the length of the heat-conducting blade 5 on the inner side of the outer main blade 14. The outer main blade 14 and each inner main blade 15 are connected by the flexible connecting tube 16. The inner main blades 15 are made of a magnetic heat-conducting material, and the cylindrical frame 8 is made of a material magnetically connected to the inner main blades 15. By setting up multi-segment inner main blades 15, under the flexible connection of the flexible connecting tube 16, the magnetic connection between the inner main blades 15 and the cylindrical frame 8 allows the heat-conducting blade 5 to more stably fit the cylindrical frame 8 when deflected. Therefore, it can cover the outside of the cylindrical frame 8, so that it can adapt to the arc-shaped shape of the cylindrical frame 8, ensuring the heat-conducting blade 5 and the cylindrical frame 8, and increasing the efficiency of heat transfer.

[0025] In this embodiment, the flexible connecting tube 16 is coiled in a serpentine shape, with both ends of the flexible connecting tube 16 connected to the hollow shaft 6. The hollow shaft 6 is rotatably sealed to the through hole 17 opened on the rectangular window 4. The hollow shaft 6 is connected to the cavity 9, and the flexible connecting tube 16 is fixedly installed in the channels 18 opened inside the outer main blade 14 and the inner main blade 15. The coolant in the cavity 9 of this invention can also flow inside the heat-conducting blades 5, forming a dual heat dissipation mechanism of internal liquid cooling + external air cooling. When the coolant flows in the serpentine flexible connecting tube 16, it can carry away heat more efficiently.

[0026] In this embodiment, a plurality of opening slots 19 are evenly spaced along the width direction of the heat-conducting blade 5 on the outer main blade 14. The spacing of the opening slots 19 corresponds to the spacing of the serpentine flexible connecting pipes 16, and the opening slots 19 are staggered within the intervals of the flexible connecting pipes 16. The heat of the coolant can be quickly dissipated into the air through the slots, avoiding heat accumulation. This design is particularly suitable for high-speed airflow environments and can significantly reduce the surface temperature of the heat-conducting blade 5.

[0027] In this embodiment, the cylindrical frame 8 includes a plurality of rings 20 evenly spaced along the axial direction of the transformer housing 2 and a connecting rod 21 for connecting each ring 20. The connecting rod 21 is parallel to the axis of the transformer housing 2 and is fixed to the inner side of the rings 20. The cylindrical frame 8 is fixedly connected to the sealing plate 3 by a support rod 22. By adopting the above-mentioned cylindrical frame 8 structure, heat resistance can be reduced while ensuring the structural strength of the cylindrical frame 8.

[0028] In this embodiment, a groove 23 is provided on the upper side of the heat-conducting blade 5. The torsion reset device 7 includes a reset torsion spring installed in the groove 23. The reset torsion spring is sleeved on the outside of the hollow shaft 6. The outer end of the reset torsion spring is connected to the transformer housing 2. The above structure is used to install the reset torsion spring without occupying extra space, so that the heat-conducting blade 5 can be closer to the transformer housing 2, and the heat dissipation air duct layout is optimized.

[0029] In this embodiment, a rotating ring plate 24 is fixed on the outer side of the transformer housing 2. A limiting groove 25 is opened on the outer edge of the rotating ring plate 24. The limiting groove 25 is used to limit the transformer housing 2 in the axial direction. The rotating ring plate 24 is rotatably installed in the rotating groove opened on the lower side panel of the air inlet pipe 1.

[0030] In this embodiment, a plurality of protrusions 26 are integrally formed on the outer side of the transformer housing 2. The protrusions 26 protrude outward from the outer surface of the transformer housing 2 and extend along the axial direction of the transformer housing 2. The inner side of the protrusions 26 forms a prismatic cavity that communicates with the cavity 9. The protrusions 26 increase the heat dissipation area and improve the liquid cooling efficiency. The prismatic cavity is in communication with the coolant, allowing heat to be quickly dissipated through the protrusions 26, thereby enhancing the overall heat dissipation capacity.

[0031] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
