Description

Technical Field

[0001] This invention relates to the field of dry-type transformer technology, specifically to a dry-type transformer for shore power with a positioning and installation function. Background Technology

[0002] Dry-type transformers are widely used in local lighting, high-rise buildings, airports, docks, CNC machinery, and other applications. Simply put, a dry-type transformer is a transformer whose core and windings are not immersed in insulating oil. Cooling methods include natural air cooling and forced air cooling. With natural air cooling, the transformer can operate continuously at its rated capacity for extended periods. With forced air cooling, the transformer's output capacity can be increased by 50%. It is suitable for intermittent overload operation or emergency overload operation. Because load losses and impedance voltage increases significantly under overload conditions, it operates in an uneconomical state and should not be subjected to prolonged continuous overload operation. It mainly consists of a silicon steel core and epoxy resin-cast coils. Insulating cylinders are placed between the high and low voltage coils to increase electrical insulation, and the coils are supported and constrained by pads. All fasteners connecting the components have anti-loosening properties.

[0003] Shore power supplies, also known as shore-based frequency converters or electronic static shore power supplies, are high-power frequency converters specifically designed and manufactured for harsh environments such as ships and shore docks, where high temperatures, high humidity, high corrosion, and heavy load impacts are encountered. All PCB circuit boards undergo coating curing treatment; the sine filter and output transformer are treated with overall vacuum impregnation with insulating varnish and sprayed with high-temperature protective varnish, providing a high level of insulation and protection. They are widely used on ships, in shipbuilding and repair shops, offshore drilling platforms, and shore docks, where a high-quality, stable frequency and voltage power supply (60Hz) is required to convert 50Hz industrial power to 60Hz for powering shipboard equipment. Dry-type transformers for shore power are a type of dry-type transformer used in shore power supplies.

[0004] Currently, shore power dry-type transformers on the market need to be installed on ships, shipbuilding and repair yards, ocean drilling platforms, and shore docks. In actual use, after a period of use, a large amount of heat is generated inside the shore power dry-type transformer, requiring natural air cooling and forced air cooling. When forced air cooling is used, the shore power dry-type transformer cannot maintain forced air cooling indefinitely, resulting in the inefficient and rapid dissipation of heat. This leads to excessively high internal temperatures, causing aging of internal components. In addition, the installation and positioning of this device is cumbersome. Summary of the Invention

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. The shore power dry-type transformer with positioning and installation function described in this invention can dissipate heat inside the dry-type transformer body.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] A positioning plate 4 is fixedly connected to the outer wall of the dry-type transformer body 1. A first groove 5 is formed inside the positioning plate 4. A motor 6 is fixedly connected inside the first groove 5. A drive shaft 7 is fixedly connected to one end of the output shaft of the motor 6. A disc 8 is fixedly connected to one end of the drive shaft 7. An air inlet pipe 9 is fixedly connected to the outer wall of the disc 8. One end of the air inlet pipe 9 passes through the outer wall of the positioning plate 4 and is fixedly connected to the positioning plate 4. A second groove 10 is formed inside the disc 8. A first pipe 11 is fixedly connected inside the second groove 10. One end of the first pipe 11 passes through the interior of the air inlet pipe 9 and is connected to the air inlet pipe 9. Pipe 9 is connected. A first one-way valve 12 is fixedly connected to the outer wall of the first pipe 11. A second pipe 13 is fixedly connected inside the second groove 10. One end of the second pipe 13 passes through the outer wall of the disc 8. The second pipe 13 is fixedly connected to the disc 8. A second one-way valve 14 is fixedly connected to the outer wall of the second pipe 13. An extrusion plate 15 is slidably connected inside the second groove 10. An extrusion rod 16 is fixedly connected to the outer wall of the extrusion plate 15. One end of the extrusion rod 16 passes through the outer wall of the disc 8. The extrusion rod 16 is slidably connected to the disc 8. A first magnet 17 is fixedly connected to the end of the extrusion rod 16 away from the extrusion plate 15.

[0038] In a preferred embodiment, a second magnet 18 is fixedly connected to the outer wall of the disk 8, a third magnet 19 is fixedly connected to the inside of the first groove 5, and a fourth magnet 20 is fixedly connected to one side of the third magnet 19. The first magnet 17 and the third magnet 19 repel each other, and the first magnet 17 and the fourth magnet 20 attract each other. When the first magnet 17 moves, the first magnet 17 will reach the side of the fourth magnet 20.

[0039] In a preferred embodiment, a first vent pipe 21 is fixedly connected inside the first groove 5. One end of the first vent pipe 21 penetrates the interior of the dry-type transformer body 1. A third one-way valve 22 is fixedly connected to the outer wall of the first vent pipe 21. A second vent pipe 23 is fixedly connected to the outer wall of the dry-type transformer body 1. One end of the second vent pipe 23 penetrates the interior of the dry-type transformer body 1. When cold gas enters the interior of the first groove 5, the cold gas will enter the interior of the first vent pipe 21.

[0040] The working principle of this invention is as follows: When using this device, it is necessary to quickly expel hot gas from the inside of a dry-type transformer used for shore power. Since forced air cooling cannot continuously expel hot gas, the motor 6 is started. The output shaft of the motor 6 drives the drive shaft 7 to rotate within the first groove 5. Simultaneously, the drive shaft 7 drives the disc 8 to rotate within the first groove 5. The disc 8 also drives the air inlet pipe 9 to rotate within the first groove 5. Simultaneously, the disc 8 drives the extrusion rod 16 to rotate within the first groove 5. The extrusion rod 16 also drives the first magnet 17 to rotate within the first groove 5. Simultaneously, the disc 8 drives the second magnet 18 to move, causing the second magnet 18 to move in a circular motion within the first groove 5. When the first magnet 17 reaches the side of the fourth magnet 20, the first magnet 17 and the fourth magnet 20 attract each other, causing the first magnet 17 to drive the extrusion rod 16 to move, causing the extrusion rod 16 to slide against the disc 8. The extrusion rod 16 simultaneously drives the extrusion plate 15 to move, causing the extrusion plate 15 to move towards the first magnet 17 and slide within the second groove 10. This allows cold gas to enter the first pipe 11 from the inlet pipe 9. Inside the first pipe 11, the cold gas passes through the first one-way valve 12, which only allows gas to enter the second groove 10 from the first pipe 11. Cold gas enters the second groove 10 from the first pipe 11. When the first magnet 17 reaches the side of the third magnet 19, the first magnet 17 and the third magnet 19 repel each other, causing the first magnet 17 to drive the extrusion rod 16 to move. The extrusion rod 16 slides against the disc 8, and the extrusion rod 16 drives the extrusion plate 15 to move towards the air inlet pipe 9. This causes the extrusion plate 15 to extrude cold gas inside the second groove 10, allowing the cold gas to enter the second pipe 13 from the second groove 10. The cold gas then passes through the second one-way valve 14 in the second pipe 13, allowing it to enter the first groove 5 from the second pipe 13. The second one-way valve 14 only allows gas to enter the second groove 5 from the second groove 10. Inside the second pipe 13, as the cold gas inside the first groove 5 gradually increases, the cold gas will enter the first outlet pipe 21 from the first groove 5. Inside the first outlet pipe 21, the cold gas passes through the third one-way valve 22. The third one-way valve 22 only allows gas to enter the dry-type transformer body 1 from the first outlet pipe 21. The cold gas will enter the dry-type transformer body 1, causing the cold gas to neutralize the hot gas inside the dry-type transformer body 1, and at the same time, it will squeeze the hot gas inside the dry-type transformer body 1, causing the hot gas to move out from the second outlet pipe 23. Repeat the above steps, so that the hot gas inside the dry-type transformer body 1 is discharged and neutralized, thereby causing the internal temperature of the dry-type transformer body 1 to drop rapidly.

[0041] Please see Figures 1-6The present invention provides a technical solution: a dry-type transformer for shore power with positioning and installation function. The positioning plate 4 has a third groove 24 inside. A stabilizing rod 25 is fixedly connected inside the third groove 24. A stabilizing plate 26 is slidably connected to the outer wall of the stabilizing rod 25. An electromagnet 27 is fixedly connected to the outer wall of the stabilizing plate 26. The electromagnet 27 and the second magnet 18 repel each other. When the stabilizing plate 26 moves, the stabilizing plate 26 will slide on the outer wall of the stabilizing rod 25.

[0042] In a preferred embodiment, a movable plate 28 is hinged to the outer wall of the stabilizing plate 26, and a fixed plate 29 is fixedly connected inside the third groove 24. A sliding groove 30 is provided on the outer wall of the fixed plate 29, and a sliding rod 31 is slidably connected inside the sliding groove 30. One end of the sliding rod 31 is fixedly connected to the outer wall of the movable plate 28. A positioning rod 32 is provided inside the third groove 24, and a strip groove 33 is provided inside the third groove 24. A fixed rod 34 is fixedly connected inside the third groove 24. When the sliding rod 31 moves, the sliding rod 31 will move inside the sliding groove 30.

[0043] In a preferred embodiment, a connecting plate 35 is slidably connected inside the strip groove 33, a roller 36 is hinged to one end of the movable plate 28, and a connecting block 37 is fixedly connected to the outer wall of the connecting plate 35. When the connecting plate 35 moves, the connecting plate 35 will slide inside the strip groove 33.

[0044] In a preferred embodiment, one end of the positioning rod 32 passes through the outer wall of the positioning plate 4, and the positioning rod 32 is slidably connected to the positioning plate 4. The outer wall of the fixing rod 34 is slidably connected to the locking rod 38, and the outer wall of the positioning rod 32 is provided with a locking groove 39. One end of the locking rod 38 is slidably connected to the locking groove 39. When the locking rod 38 moves, the locking rod 38 will move inside the third groove 24.

[0045] In a preferred embodiment, a connecting rod 40 is fixedly connected to the outer wall of the locking rod 38, and a spring 41 is fixedly connected to one end of the locking rod 38. When the locking rod 38 moves, the locking rod 38 will drive the spring 41 to move.

[0046] In a preferred embodiment, one end of the positioning rod 32 passes through the outer wall of the positioning plate 4, and the positioning rod 32 is slidably connected to the positioning plate 4. One end of the positioning rod 32 is fixedly connected to the mounting plate 42, and a bolt 43 passes through the inside of the mounting plate 42. The bolt 43 is connected to the mounting plate 42 by threads. When the positioning rod 32 moves, the positioning rod 32 will drive the mounting plate 42 to move.

[0047] In a preferred embodiment, the number of third grooves 24 is set to two, and the two third grooves 24 are symmetrically distributed inside the positioning plate 4. When the roller 36 moves, the roller 36 will move inside the third groove 24.

[0048] The working principle of this invention is as follows: When using this device and positioning is required, bolt 43 is used to pass through the mounting plate, causing the mounting plate 42 to be positioned on the side of the wall where it needs to be installed. One end of bolt 43 is connected to the wall. When the positions of the mounting plate 42 and the positioning rod 32 are fixed, the electromagnet 27 is energized, starting the motor 6. The output shaft of the motor 6 drives the drive shaft 7 to move, which in turn drives the disc 8 to rotate within the first groove 5. The disc 8 then drives the second magnet 18 to move, causing the second magnet... The second magnet 18 moves in a circular motion inside the first groove 5. When the second magnet 18 moves to the side of the electromagnet 27, the motor 6 stops. The electromagnet 27 and the second magnet 18 repel each other, causing the electromagnet 27 to drive the stabilizing plate 26 to move. The stabilizing plate 26 slides inside the third groove 24. At the same time, the stabilizing plate 26 slides on the outer wall of the stabilizing rod 25. When the stabilizing plate 26 drives the movable plate 28 to move, the movable plate 28 swings inside the third groove 24. The movable plate 28 drives the sliding rod 31 to move, causing the sliding rod 31 to slide inside the sliding groove 30. Simultaneously, the movable plate 28 drives the roller 36 to move. When the roller 36 reaches one side of the connecting plate 35, the roller 36 presses against the connecting plate 35, causing the connecting plate 35 to slide inside the third groove 24. The connecting plate 35 also slides inside the strip groove 33. Simultaneously, the connecting plate 35 drives the connecting block 37 to move, causing the connecting block 37 to slide inside the third groove 24. The cross-sectional shape of the connecting block 37 is set as an isosceles trapezoid, allowing the connecting block 37 to press against the connecting rod 40, causing the connecting rod 40 to drive the locking rod 38 to move, causing the locking rod 38 to... The sliding movement of the outer wall of the fixed rod 34 causes one end of the locking rod 38 to fully enter the third groove 24, and one end of the positioning rod 32 to enter the third groove 24. This de-energizes the electromagnet 27, causing it to lose its magnetic force. Consequently, the locking rod 38 loses the external force from the connecting rod 40, and the spring 41 compresses the locking rod 38, causing it to return to its initial position. This allows one end of the locking rod 38 to enter the locking groove 39. Simultaneously, the locking rod 38 drives the connecting block 37 and the connecting plate 35, causing the movable plate 28 and the stabilizing plate 26 to return to their original positions.
