Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a transformer with a moisture-proof function. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components are the primary coil, secondary coil, and iron core. In electrical equipment and radio circuits, it is commonly used for stepping up or down voltages, matching impedances, safety isolation, etc.

[0003] For example, the utility model with the publication number CN217333769U discloses a small transformer with a moisture-proof function, including a heat-conducting frame, a transformer body fixedly connected to the heat-conducting frame, a base, and a protective cover detachably connected to the base. The transformer body is fixedly installed in the inner cavity of the heat-conducting frame, and the base is horizontally fixedly installed on the lower surface of the heat-conducting frame. The utility model relates to the technical field of small transformers. This small transformer with a moisture-proof function can seal and protect the transformer body through the heat-conducting frame and the sealing plate, preventing moisture from corroding the transformer body when it is humid nearby. At the same time, heat conduction can be carried out through the heat dissipation plate on the surface of the heat-conducting frame. When the temperature of the transformer body is too high, the high temperature can be introduced into the inner wall of the heat dissipation plate through the heat-conducting frame. Subsequently, when the air contacts the heat dissipation plate through the heat dissipation holes inside the protective cover and the connecting plate, heat dissipation can be carried out. While not affecting the heat dissipation of the transformer body, the transformer body can be moisture-proofed, improving the protection performance.

[0004] However, in the prior art, when the existing transformer works in a relatively humid environment, the transformer will be affected by external moisture, resulting in short circuits or corrosion, affecting the normal use of the device, thus limiting the practicality of the device to a certain extent.

[0009] As a preferred implementation manner, through holes are symmetrically formed in the lower surface of the heat dissipation frame, and the sizes of the through holes are the same as those of the base of the transformer body.

[0010] As a preferred implementation manner, fixing blocks are symmetrically and fixedly connected to the lower surface of the heat dissipation frame, and a bidirectional lead screw is movably connected to the middle of the two fixing blocks.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4The utility model provides a technical solution: a transformer with moisture-proof function, including a heat dissipation frame 1, a transformer body 16 is built in the heat dissipation frame 1, and the inner cavity of the heat dissipation frame 1 is symmetrically connected to the two sides of the transformer body 16 for rotation, and a driving component is arranged on the upper surface of the heat dissipation frame 1, and the top of the worm 9 is connected to the bevel gear B10 for transmission, and the inner cavity of the heat dissipation frame 1 is located in the middle of the transformer body 16 and the worm 9. The dehumidification component includes a fixed frame 11, and a plurality of heating wires 12 are fixedly connected to one side of the inner wall of the fixed frame 11 close to the transformer body 16, and a rotating shaft 13 is rotatably connected at the axis of the fixed frame 11, and one end of the rotating shaft 13 is fixedly connected There is a worm gear 14, and the other end of the rotating shaft 13 is fixedly connected with a fan blade 15, and the worm gear 14 is meshed with the worm 9, and the outer wall of the heat dissipation frame 1 is symmetrically fixedly connected with a plurality of equidistantly arranged heat dissipation tubes 2. When the driving component drives the worm 9 to rotate through the bevel gear B10, the worm 9 will synchronously drive the worm gear 14 to rotate, and the worm gear 14 drives the fan blade 15 to rotate through the rotating shaft 13, so that the moisture near the transformer is heated by the heating wire 12 and discharged from the heat dissipation tube 2 to the outside, thereby effectively reducing the impact of moisture on the transformer, and the heat dissipation tube 2 is designed to be inclined downward at 45 degrees, which effectively reduces the entry of moisture without affecting the heat dissipation, thereby ensuring the dryness inside the device.

[0023] like Figures 1-4 As shown, the driving assembly includes a mounting frame 3, which is fixedly connected to the upper surface of the heat dissipation frame 1, and a movable rod 4 is movably connected to the middle part of the mounting frame 3, and a driven gear 6 is fixedly connected to the middle part of the movable rod 4, and bevel gears A5 are symmetrically connected to both ends of the movable rod 4, and the bevel gears A5 and the bevel gears B10 are meshed with each other. A motor 7 is fixedly connected to the side of the upper surface of the mounting frame 3 close to the driven gear 6, and the output shaft of the motor 7 is connected to the spur gear 8, and the spur gear 8 and the driven gear 6 are meshed with each other. The output shaft of the motor 7 drives the driven gear 6 to rotate through the spur gear 8, and the driven gear 6 drives the bevel gears A5 on both sides to rotate through the movable rod 4, and the bevel gear A5 drives the worm 9 to rotate through the bevel gear B10, thereby driving the fan blades 15 to rotate, thereby dehumidifying while dissipating heat to the transformer body 16, thereby improving the overall safety of the device.

[0024] like Figures 1-4As shown in the figure, through holes 17 are symmetrically formed on the lower surface of the heat dissipation frame 1, and the size of the through holes 17 is the same as that of the base of the transformer body 16. Fixed blocks 18 are symmetrically and fixedly connected to the lower surface of the heat dissipation frame 1. A bidirectional lead screw 19 is movably connected to the middle of the two fixed blocks 18. Displacement blocks 20 are symmetrically and threadedly connected to the surface of the bidirectional lead screw 19. Baffles 21 are fixedly connected to one side of the two displacement blocks 20. When the transformer body 16 is not in use, the bidirectional lead screw 19 drives the displacement blocks 20 on both sides to move towards each other, so that the baffle 21 seals the through hole 17, preventing external dust and moisture from entering, and further improving the overall safety of the device.

[0025] As Figures 1-4 shown, an installation block 22 is fixedly connected to the outer side wall of the fixed block 18 above the bidirectional lead screw 19. A screw 23 is threadedly connected to the middle of the installation block 22. A positioning block 24 is fixedly connected to one end of the screw 23, and the positioning block 24 abuts against one end of the bidirectional lead screw 19. The screw 23 drives the positioning block 24 to move downward to limit the bidirectional lead screw 19, improving the sealing effect of the baffle 21 on the through hole 17.

[0026] Working principle:

[0027] During use, first place the transformer body 16 in the inner cavity of the heat dissipation frame 1. When working in a humid environment, the output shaft of the motor 7 drives the driven gear 6 to rotate through the spur gear 8. The driven gear 6 drives the bevel gears A5 on both sides to rotate through the movable rod 4. The bevel gear A5 drives the worm 9 to rotate through the bevel gear B10. The worm 9 will synchronously drive the worm gear 14 to rotate. The worm gear 14 drives the fan blade 15 to rotate through the rotating shaft 13, so that the moisture near the transformer is heated by the heating wire 12 and discharged to the outside through the heat dissipation pipe 2, effectively reducing the influence of moisture on the transformer. The heat dissipation pipe 2 is designed at an angle of 45 degrees obliquely downward, effectively reducing the probability of moisture entering the heat dissipation frame 1. At the same time, when the transformer body 16 is not in use, rotate the bidirectional lead screw 19. The bidirectional lead screw 19 drives the baffles 21 on both sides to move towards each other through the displacement blocks 20, so as to seal the through holes 17 and prevent moisture from entering, thereby maintaining the dryness of the transformer body 16 inside the heat dissipation frame 1. After the sealing is completed, rotate the screw 23. The screw 23 drives the positioning block 24 to move downward, thereby limiting the bidirectional lead screw 19 and preventing the bidirectional lead screw 19 from loosening and affecting the sealing effect, avoiding damage to the transformer body caused by moisture, improving the overall safety of the device, and extending the service life of the transformer.

[0028] The above are only the preferred embodiments of the present utility model, and do not limit the present utility model in other forms. Any person skilled in the relevant art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
