[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] A dust-proof and noise-proof energy-saving dry-type transformer, such as Figures 1-6 As shown, it includes a mounting base 1, the upper end of the mounting base 1 is fixedly connected to a transformer body 2, the upper end of the transformer body 2 is fixedly connected to a top plate 3, the middle part of the top plate 3 is rotatably connected to a heat dissipation component, four groups of side frames 5 are fixedly connected between the top plate 3 and the mounting base 1, and side plates 7 are slidably connected between two adjacent groups of side frames 5. One side of multiple groups of side plates 7 is fixedly connected to a rack 8, and multiple groups of racks 8 pass through the top plate 3. Multiple groups of drive components are fixedly connected to the upper end of the top plate 3, and the multiple groups of drive components are respectively engaged with the multiple groups of racks 8 for transmission.

[0026] The side panels 7 are controlled to rise and fall by engaging the driving assembly with the rack 8. The side frames 5 ensure that the side panels 7 will not fall over when they are raised and lowered. The side panels 7 are raised and lowered according to the wind direction, so that the side panels 7 that are in conflict with the wind direction are lowered, thereby preventing dust carried in the wind from covering the surface of the transformer body 2, thereby preventing the transformer body 2 from being covered with too much dust and affecting the heat dissipation effect of the transformer. The lowered side panels 7 will not block the wind from blowing the heat dissipation components, and the heat dissipation components accelerate the air flow under the top plate 3, thereby improving the heat dissipation effect of the transformer body 2.

[0027] The heat dissipation assembly includes a rotating rod 13, which is rotatably connected to the top plate 3. The side wall of the rotating rod 13 is fixedly connected to a limit plate 14, and the limit plate 14 is located above the top plate 3. The upper end of the rotating rod 13 is fixedly connected to a connecting plate 15, and a plurality of through-holes 16 are formed on the connecting plate 15.

[0028] like Figures 1-6 As shown, the rotating rod 13 is rotatably connected to the top plate 3, the limiting plate 14 prevents the rotating rod 13 from falling, and the connecting plate 15 is used to connect the rotating rod 13 with other parts.

[0029] Multiple groups of the through-holes 16 are each inserted with an insert plate 18, and the upper ends of the multiple groups of insert plates 18 are commonly fixed with a driving fan 17. The side wall of the rotating rod 13 is located above the limit plate 14 and is sleeved with a nut 19. The inner wall of the nut 19 is threadedly connected to the outer wall of the multiple groups of insert plates 18.

[0030] like Figures 1-6As shown, the plug-in plate 18 at the lower end of the driving fan 17 is inserted into the through-hole 16 of the connecting plate 15. The multiple sets of plug-in plates 18 are all arc-shaped, and the multiple sets of plug-in plates 18 form a ring. After insertion, the nut 19 is screwed so that the nut 19 is screwed on the multiple sets of plug-in plates 18, so that the multiple sets of plug-in plates 18 will not be separated from the connecting plate 15, which is convenient for disassembly and assembly of the driving fan 17 and easy maintenance.

[0031] A fixed frame 20 is fixedly connected to the bottom of the top plate 3, and a drive motor 21 is rotatably connected inside the fixed frame 20. The lower end of the rotating rod 13 is fixedly connected to the upper end of the drive motor 21. A cooling fan 22 is fixedly connected to the output end of the drive motor 21. The cooling fan 22 is located between the transformer body 2 and the top plate 3.

[0032] like Figures 1-6 As shown, when wind blows towards the driving fan 17, the driving fan 17 rotates, driving the rotating rod 13 to rotate, so that the rotating rod 13 drives the driving motor 21 to rotate, and the cooling fan 22 rotates accordingly, thereby achieving the purpose of converting wind energy into mechanical energy, making the dry-type transformer more energy-efficient. When there is no wind, the driving motor 21 drives the cooling fan 22 to rotate, which also improves the heat dissipation effect of the transformer.

[0033] The driving assembly includes a fixing base 9, which is fixed to the upper end of the top plate 3. A servo motor 10 is clamped in the fixing base 9. A gear 11 is fixed to the output end of the servo motor 10. The gear 11 is meshed with the rack 8 for transmission.

[0034] like Figure 1-Figure 2 As shown, the servo motor 10 drives the gear 11 to rotate, and the gear 11 drives the rack 8 to transmit, so that the side panel 7 is raised and lowered.

[0035] A sound-absorbing pad 12 is fixedly connected to the lower end of the top plate 3 , and a rectangular opening is opened in the middle of the sound-absorbing pad 12 .

[0036] like Figure 3 As shown, the noise-absorbing pad 12 absorbs the noise generated by the transformer to prevent the dry-type transformer from making too much noise, and the rectangular opening facilitates the rotation of the heat dissipation component.

[0037] The working principle of the dust-proof and noise-proof energy-saving dry-type transformer provided by the utility model is as follows:

[0038] The side panels 7 are controlled to rise and fall by engaging the driving assembly with the rack 8. The side frames 5 ensure that the side panels 7 will not fall over when they are raised and lowered. The side panels 7 are raised and lowered according to the wind direction, so that the side panels 7 that are in conflict with the wind direction are lowered, thereby preventing dust carried in the wind from covering the surface of the transformer body 2, thereby preventing the transformer body 2 from being covered with too much dust and affecting the heat dissipation effect of the transformer. The lowered side panels 7 will not block the wind from blowing the heat dissipation components, and the heat dissipation components accelerate the air flow under the top plate 3, thereby improving the heat dissipation effect of the transformer body 2.

[0039] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
