[0001] This invention relates to the technical field of transformer dustproof heat dissipation grilles, specifically to a transformer with a dustproof heat dissipation grille. Background Technology

[0002] A transformer is an electrical device that uses the principle of electromagnetic induction to change AC voltage. It mainly consists of a primary coil, a secondary coil, and an iron core, and achieves the transformation of voltage, current, and impedance through electromagnetic induction.

[0003] Transformers need to dissipate heat during use, but to prevent moisture and dust from adhering to the transformer, dustproof heat dissipation grids need to be installed on the transformer surface. Existing dustproof heat dissipation grids are mainly composed of dustproof nets and water-absorbing cotton, which are mainly used to absorb moisture and dust in the air. However, after long-term use, the water absorption and dust prevention efficiency of the dustproof heat dissipation grids decreases, making it impossible to meet the normal use of the transformer.

An adjusting component is slidably connected in the moving groove, and the adjusting component is in contact with the swinging component. The air suction component is in slidable contact with the adjusting component.

[0006] Furthermore, the swinging component includes a rotating rod, which is installed in the communicating groove. A swinging cylinder is rotatably connected to the annular surface of the rotating rod. Swinging plates are installed on both sides of the annular surface of the swinging cylinder. The swinging plates extend into the rectangular groove and contact the dustproof heat dissipation plate. The side of the swinging plate away from the dustproof heat dissipation plate contacts the adjusting component.

[0007] Furthermore, the adjusting component includes an adjusting plate, which is slidably connected in a moving groove. Two inclined grooves are formed at the center of the upper surface of the adjusting plate, and pressing components are installed in the two inclined grooves. The pressing components are in contact with the swing plate. Two circular holes are formed on both sides of the upper surface of the adjusting plate, and a first one-way valve and a second one-way valve are respectively installed in the two circular holes. The circular holes are in contact with the exhaust holes. The connecting component is installed on the lower side of the circular holes. Sealing components are installed on both sides of the lower surface of the adjusting plate, and the end of the sealing component away from the adjusting plate is connected to the connecting component.

[0008] Furthermore, the extrusion component includes a support plate, which is installed at the center of the lower surface of the outer plate. Rectangular holes are provided on both sides of the horizontal part of the support plate. A first inclined block is inserted into the rectangular hole. The first inclined block is inserted into the inclined groove, and the end of the first inclined block away from the inclined groove is in contact with the swing plate.

[0009] Furthermore, the suction component includes a fan, which is installed inside a sealing frame. Both the input and output ends of the fan are equipped with connecting parts. The end of the connecting part away from the fan is in contact with a circular hole. A sealing part is installed inside the connecting part, and the sealing part is connected to an adjusting plate.

[0010] Furthermore, the connecting component includes a connecting pipe, which is disposed within the sealing frame and indirectly contacts the circular hole. An air inlet pipe and an exhaust pipe are installed at the end of the connecting pipe away from the circular hole. The air inlet pipe is connected to the input end of the fan, and the exhaust pipe is connected to the output end of the fan. A sealing sleeve is installed on the annular surface of both the air inlet pipe and the exhaust pipe, and the sealing component is installed inside the sealing sleeve.

[0011] Furthermore, the sealing component includes multiple sealing blocks, the upper surface of the sealing sleeve has a slot, the sealing block is inserted into the slot, the upper surface of the adjusting plate is equipped with a second inclined block, the second inclined block is in contact with the sealing block, and an elastic element is installed on one side of the sealing block outside the sealing sleeve, the end of the elastic element away from the sealing block is connected to the sealing sleeve.

[0012] Furthermore, a magnet is installed at the bottom of the rectangular groove, and iron plates are installed at both ends of the swing plate, with the iron plates in contact with the magnet.

[0015] This invention provides a transformer with a dustproof heat dissipation grille, which has the following beneficial effects:

[0016] 1. This invention features rectangular slots on both sides of the outer plate, with dustproof heat dissipation plates slidably connected within these slots. When the transformer is cooling down, a fan draws in air through one side of the dustproof heat dissipation plate to cool the transformer, and then discharges the air from the other side, carrying away the heat emitted by the transformer body. Simultaneously, as the air is discharged from the other side, it blows away the dust filtered on the other side and dries the moisture absorbed by the absorbent cotton, thereby increasing the service life of the dustproof heat dissipation plate.

[0017] 2. In this invention, a connecting groove is opened between two rectangular grooves, and a swing structure consisting of a rotating rod, a swing cylinder, and a swing plate is installed in the connecting groove. The swing structure is used to weigh the two dustproof heat dissipation plates on the outer plate. After weighing, the pressing structure consisting of a support plate and a first inclined block drives the adjusting plate to move, so that the rectangular groove on the lighter side of the dustproof heat dissipation plate is connected to the input end of the fan, and the rectangular groove on the heavier side of the dustproof heat dissipation plate is connected to the output end of the fan, thereby ensuring that the dustproof heat dissipation plates on both sides are consumed evenly.

[0018] 3. The present invention provides a slot on the upper surface of the sealing sleeve, inserts a sealing block into the slot, and installs a second inclined block on the lower surface of the adjusting plate. The second inclined block contacts the sealing block and forces the sealing block into the slot, thereby sealing the air inlet pipe and the exhaust pipe and preventing the air inlet pipe and the exhaust pipe on the same side from being connected, which would reduce the heat dissipation efficiency of the transformer.

[0029] Please refer to Figures 1 to 9. The present invention provides a technical solution: a transformer with a dustproof heat dissipation grid, comprising a transformer body 1, with multiple outer plates 2 disposed on the outer side of the transformer body 1. Partition plates 6 are installed at the contact points of the multiple outer plates 2 and at the center of the side of the outer plates 2 facing the transformer body 1. The end of the partition plate 6 away from the outer plates 2 is connected to the transformer body 1. The space between the outer plates 2 and the transformer body 1 is divided into multiple parts by the multiple partition plates 6. Rectangular grooves 7 are opened on both sides of the partition plates 6 on the outer plates 2. A dustproof heat dissipation plate 3 is slidably connected in the rectangular grooves 7. The dustproof heat dissipation plate 3 is composed of a dustproof net and water-absorbing cotton. Outside air enters the space composed of multiple outer plates 2 through the dustproof heat dissipation plate 3, and then cools the transformer body 1. A sealing gasket 5 is installed in the rectangular grooves 7. The sealing gasket 5 slides in contact with the edge of the dustproof heat dissipation plate 3, and the sealing gasket 5 seals the dustproof heat dissipation plate 3.

[0030] Multiple sealing frames 4 are installed at the bottom of the transformer body 1. The outer plate 2 is installed on the upper surface of the sealing frame 4. A moving groove 19 is opened on the side of the sealing frame 4 that contacts the outer plate 2. An exhaust hole 8 is opened between the moving groove 19 and the rectangular groove 7. An adjusting plate 18 is slidably connected in the moving groove 19. Two round holes are opened on both sides of the upper surface of the adjusting plate 18. The round holes contact the exhaust hole 8. A first one-way valve 15 and a second one-way valve 16 are installed in the two round holes respectively. The first one-way valve 15 only allows air from the top to pass through, and the second one-way valve 16 only allows air from the bottom to pass through. Multiple rotating rollers 20 are installed on both sides of the moving groove 19. The rotating rollers 20 rotate and contact the adjusting plate 18, and the rotating rollers 20 reduce the friction of the adjusting plate 18 during movement.

[0031] A fan 24 is installed on the lower surface of the sealing frame 4. A connecting pipe 21 is installed inside the sealing frame 4. The connecting pipe 21 is in indirect contact with the round hole. An air inlet pipe 23 and an exhaust pipe 22 are installed at the end of the connecting pipe 21 away from the round hole. The air inlet pipe 23 is connected to the input end of the fan 24, and the exhaust pipe 22 is connected to the output end of the fan 24. When the fan 24 is started, air is drawn in through the dustproof heat sink 3 on one side to cool the transformer. Then the air is discharged from the dustproof heat sink 3 on the other side, and the heat dissipated by the transformer body 1 is carried away again. At the same time, when the air is discharged from the dustproof heat sink 3 on the other side, the air can blow away the dust filtered on the dustproof heat sink 3 on the other side and dry the moisture absorbed by the water-absorbing cotton, thereby increasing the service life of the dustproof heat sink 3.

[0032] A connecting groove 9 is provided between the two rectangular grooves 7. A rotating rod 10 is installed in the connecting groove 9. A swing cylinder 11 is rotatably connected to the annular surface of the rotating rod 10. Swing plates 12 are installed on both sides of the annular surface of the swing cylinder 11. The swing plates 12 extend into the rectangular grooves 7 and come into contact with the dustproof heat dissipation plate 3. As the dustproof heat dissipation plate 3 absorbs and filters dust and moisture, the weight of the dustproof heat dissipation plate 3 increases. The heavier of the two dustproof heat dissipation plates 3 will be lifted by the swing plates 12.

[0033] Both the intake pipe 23 and the exhaust pipe 22 are fitted with sealing sleeves 25 on their annular surfaces. The upper surface of the sealing sleeve 25 has a slot, into which a blocking block 27 is inserted. The upper surface of the adjusting plate 18 is fitted with a second inclined block 28, which is in contact with the blocking block 27. An elastic element 26, which is a spring, is installed on one side of the blocking block 27 outside the sealing sleeve 25. In its normal state, the end of the elastic element 26 away from the blocking block 27 is connected to the sealing sleeve 25. A support plate 30 is then installed at the center of the lower surface of the outer plate 2. Rectangular holes are opened on both sides of the horizontal part, into which a first inclined block 29 is inserted. Two inclined grooves 17 are opened at the center of the upper surface of the adjusting plate 18. The first inclined block 29 is inserted into the inclined groove 17, and the end of the first inclined block 29 away from the inclined groove 17 is in contact with the swing plate 12.

[0034] The two dustproof heat dissipation plates 3 on the outer plate 2 are weighed by the swing structure consisting of the rotating rod 10, the swing cylinder 11 and the swing plate 12. After weighing, the adjusting plate 18 is moved by the extrusion structure consisting of the support plate 30 and the first inclined block 29, so that the rectangular groove 7 on the lighter side of the dustproof heat dissipation plate 3 is connected to the input end of the fan 24, and the rectangular groove 7 on the heavier side of the dustproof heat dissipation plate 3 is connected to the output end of the fan 24. This ensures that the dustproof heat dissipation plates 3 on both sides are consumed evenly. Furthermore, the second inclined block 28 contacts the sealing block 27 and squeezes the sealing block 27 into the slot to seal the air inlet pipe 23 and the exhaust pipe 22, so as to prevent the air inlet pipe 23 and the exhaust pipe 22 on the same side from being connected, which would reduce the heat dissipation efficiency of the transformer.

[0035] To prevent the swing structure from swinging back and forth due to the weight change of the dustproof heat dissipation plates 3 on both sides, a magnet 13 is installed at the bottom of the rectangular groove 7, and iron plates 14 are installed at both ends of the swing plate 12. The magnet 13 is used to attract the iron plates, thereby reducing the frequency of the swing structure swinging back and forth.

[0036] In summary, when using this type of transformer with a dustproof heat dissipation grid, firstly, one of the dustproof heat dissipation plates 3 on the outer plate 2 is pushed downward to press the swing plate 12, so that the iron piece 14 on the swing plate 12 contacts the magnet 13. When the swing plate 12 on one side of the swing cylinder 11 deflects downward, the swing plate 12 presses the first inclined block 29, so that the first inclined block 29 contacts the inclined groove 17 on the adjusting plate 18, and the adjusting plate 18 is moved in the moving groove 19 by pressing the inclined groove 17. After the adjusting plate 18 moves, the positions of the first one-way valve 15 and the second one-way valve 16 installed on the adjusting plate 18 change. At the same time as the adjusting plate 18 moves, the second inclined block 28 moves.

[0037] Suppose that the right swing plate 12 is deflected downwards at this time, so that the right iron plate 14 contacts the right magnet 13. At this time, the left dustproof heat dissipation plate 3 is raised. At the same time, the right swing plate 12 drives the first inclined block 29 to squeeze the adjusting plate 18, so that the adjusting plate 18 moves to the right. At this time, the second one-way valve 16 on the right side of the adjusting plate 18 contacts the right connecting pipe 21, and the first one-way valve 15 on the left side of the adjusting plate 18 contacts the left connecting pipe 21. While the adjusting plate 18 is moving, the adjusting plate 18 drives the second inclined block 28 to move. The second inclined block 28 moves and squeezes the sealing block 27 to block the left exhaust pipe 22 and the right intake pipe 23.

[0038] When the fan 24 is started, air enters the input end of the fan 24 through the first one-way valve 15, the left connecting pipe 21 and the left air inlet pipe 23. Then the fan 24 discharges the air through the right exhaust pipe 22, the right connecting pipe 21 and the second one-way valve 16, and enters the space between the outer plate 2 and the transformer body 1. Then the air is discharged through the right dustproof heat dissipation plate 3. When the air enters, the outside air comes into contact with the transformer body 1 and cools the transformer body 1. When the air is discharged, the air comes into contact with the transformer body 1 and takes away the heat. When the air is discharged, it dries the water-absorbing cotton on the right dustproof heat dissipation plate 3 and blows away the dust on the dustproof net, thereby increasing the service life of the water-absorbing cotton and the dustproof net.

[0039] When the absorbent cotton on the right dustproof heat sink 3 is dried and the dust on the dustproof net is blown away, the weight of the right dustproof heat sink 3 decreases and the weight of the left dustproof heat sink 3 increases. When the weight of the left dustproof heat sink 3 increases and overcomes the attraction of the magnet 13, the left dustproof heat sink 3 squeezes the swing plate 12 and deflects downward, and the weight of the right dustproof heat sink 3 increases. At this time, the right dustproof heat sink 3 filters the moisture and dust in the air, and the exhaust air dries the absorbent cotton on the left dustproof heat sink 3 and blows away the dust on the dust net.

[0040] The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and to design various embodiments with various modifications suitable for a particular purpose.
