Description

Technical Field

[0001] This invention relates to the technical field of marine transformers, and in particular to a dry-type transformer for marine applications. Background Technology

[0002] Marine transformers are power conversion devices specifically designed for ships, port terminals, and offshore platforms. In marine transport, they require type approval from classification societies and are responsible for adjusting the voltage generated by generators to suit the voltage requirements of various electrical equipment on board, ensuring the stable operation of the ship's electrical systems. The prior art patent CN208608034U discloses a dry-type transformer for ships. When the current displayed on the ammeter is large, the transformer load is large, and the transformer generates a lot of heat. At this time, the internal temperature of the transformer detected by the temperature sensor rises. When the threshold is reached, the controller controls the drive motor to rotate, which drives the fan blades and auxiliary cooling fan to rotate. The heat is quickly carried away by the heat conduction plate and the hot air is discharged from the fan heat window. When the effect of the condenser deteriorates, the condenser in the condenser is replaced through the condenser filling pipe, so as to ensure the high-speed and effective heat dissipation of the transformer, thereby improving the heat dissipation efficiency of the transformer. This results in a lower temperature when the transformer is working at full load, thus improving the working efficiency of the transformer. However, when ships are sailing at sea, the filters used for heat dissipation prevent salt spray from accumulating on them, which hinders normal heat dissipation. This requires regular disassembly and cleaning, which is not only cumbersome, but also prevents proper heat dissipation after disassembly. Furthermore, the ship's hull movement during navigation can cause the transformer to loosen, making it prone to problems with fasteners. Therefore, there are areas for improvement.

A liquid pump 23 is installed on the top of the replacement box 15. The inlet end of the liquid pump 23 is connected to a liquid pumping pipe 22, and one end of the liquid pumping pipe 22 is inserted into the storage tank 21. The outlet end of the liquid pump 23 is connected to a liquid delivery pipe 24, and one end of the liquid delivery pipe 24 is fixedly inserted into the cleaning box 18. A rinsing cylinder 25 is installed at one end of the liquid delivery pipe 24, and multiple rinsing heads are installed below the rinsing cylinder 25. A placement plate 26 is installed on the inner wall of the cleaning box 18 below the rinsing heads, and a placement groove 27 is opened in the middle of the placement plate 26. The right side of the cleaning box 18 has a hinged door 20. The scrubbing structure includes: two guide rail plates 33 connected between the inner walls of the front and rear sides of the cleaning tank 18; guide grooves 32 are provided on the guide rail plates 33; a moving plate 29 is slidably arranged in the two guide grooves 32; a cleaning rod 30 is rotatably passed through the moving plate 29; a cleaning cylinder 31 is fixedly sleeved on the cleaning rod 30; bristles are provided on the cleaning cylinder 31; a cylinder 28 is installed on the rear side of the cleaning tank 18; one end of the output shaft of the cylinder 28 is connected to the moving plate 29.

When dissipating heat generated during the operation of the transformer body 3 inside the transformer box 2, the exhaust fan 14 is started to draw outside air into the transformer box 2, and the heat generated by the transformer body 3 inside the transformer box 2 is discharged from the air outlet slot 4 to perform heat dissipation. When the filter screen 7 at the air inlet slot 6 needs to be removed and cleaned after long-term use, the box door 16 is opened, and the filter screen 7 stored in the storage frame 17 is inserted into the mounting ring 12 below. Then, the motor 49 is started to drive the switching plate 11 at one end of the switching shaft 10 to rotate half a turn, and the replaced filter screen 7 is switched to the air inlet slot 6 to continue the heat dissipation work. At the same time, the filter screen 7 that needs to be cleaned is rotated to the replacement slot 9 below, and the corresponding filter screen is pulled out from the mounting ring 12 in the replacement slot 9. 2. Then, open the box door 20 and place the disassembled filter screen 27 into the middle placement slot 27 on the placement plate 26. Close the box door 20 and start the liquid pump 23. The cleaning liquid in the storage tank 21 is transported to the rinsing cylinder 25 through the liquid pumping pipe 22 and the liquid delivery pipe 24. The rinsing head below the rinsing cylinder 25 sprays the rinsing liquid onto the filter screen 27. During this process, the cylinder 28 is started to drive the moving plate 29 to move back and forth on the guide rail plate 33. The bristles on the cleaning cylinder 31 are used to brush the filter screen 27. During the movement of the moving plate 29, the gear 34 rolls on the fixed strip 35, which drives the cleaning cylinder 31 and the bristles to rotate as a whole, so that the filter screen 27 is cleaned more thoroughly. After cleaning, the filter screen 27 is stored in the storage frame 17.

[0020] See Figure 1 and Figure 9 The adaptive anti-sway structure includes: multiple fixed columns 37 connected between the inner walls of both sides of the support frame 1, and sleeves 38 movably fitted on the multiple fixed columns 37; a counterweight 39 is fixedly embedded under the sleeves 38; a swaying seat 36 is set in the middle of the bottom of the transformer box 2, and teeth are provided between the swaying seat 36 and the sleeves 38 for mutual meshing connection; buffer sleeves 40 are movably fitted on both ends of the uppermost fixed column 37, and two springs 41 are fitted on the corresponding fixed column 37, with the two ends of the springs 41 connected to the buffer sleeves 40 and the support frame 1 respectively; The guiding structure includes: a fastening plate 42 connected to the inner walls of both ends of the support frame 1, with a guide seat 43 installed at one end of the fastening plate 42; a guide plate 44 fastened to both ends of the transformer box 2, with a guide groove 45 slidably disposed in the guide seat 43 on the guide plate 44; the locking structure includes: a fixing frame 46 disposed on the upper edge of the support frame 1. Threaded rods 47 rotate through the threaded grooves on both sides of the fixed frame 46. A rotating wheel 48 is fixedly fitted onto one end of the threaded rod 47, and a locking disc 19 is fixedly installed at the other end. The locking disc 19 abuts against the transformer box 2. When the ship is sailing on the sea, the rotating wheel 48 in the fixed frame 46 rotates the threaded rods 47, causing the locking disc 19 to move and disengage from the transformer box 2. This releases the locking mechanism on the transformer box 2 from the fixed frame 46. Thus, when the ship rocks, it will cause the transformer box 2 and the transformer... The main body 3 of the device shakes as a whole. During this process, the counterweight 39 and the sleeve 38 shake in the corresponding direction of the fixed column 37. Under the action of the teeth on the sleeve 38 and the shaking seat 36, the transformer box 2 is driven to rotate in the opposite direction to buffer the shaking. The guide plate 44 on the transformer box 2 slides on the guide seat 43 to increase the stability during the anti-shaking process. The buffer sleeve 40 and the spring 41 on the fixed column 37 also buffer the sleeve 38 to prevent the sleeve 38 from directly hitting the support frame 1 and generating noise.

[0021] The implementation principle of a dry-type transformer for ships according to an embodiment of the present invention is as follows: When dissipating heat generated during the operation of the transformer body 3 inside the transformer box 2, the exhaust fan 14 is started to draw outside air into the transformer box 2, and the heat generated by the transformer body 3 inside the transformer box 2 is discharged from the air outlet slot 4 to perform heat dissipation. When the filter screen 7 at the air inlet slot 6 needs to be disassembled and cleaned after long-term use, the box door 16 is opened, and the filter screen 7 stored in the storage frame 17 is inserted into the mounting ring 12 below. Then, the motor 49 is started to drive the switching plate 11 at one end of the switching shaft 10 to rotate half a turn. The replaced filter screen 7 is switched to the air inlet slot 6 to continue heat dissipation. Simultaneously, the filter screen 7 to be cleaned is rotated into the replacement slot 9 below. The corresponding filter screen 7 is pulled out from the mounting ring 12 inside the replacement slot 9. Then, the box door 20 is opened, and the removed filter screen 7 is placed in the middle placement slot 27 on the placement plate 26. The box door 20 is closed, and the liquid pump 23 is started. The cleaning solution in the storage tank 21 is transported to the rinsing cylinder 25 through the liquid pump pipe 22 and the liquid delivery pipe 24. The rinsing head below the rinsing cylinder 25 sprays rinsing solution onto the filter screen 7. During this process, the system is activated. Cylinder 28 drives the moving plate 29 to move back and forth on the guide rail 33, brushing the filter screen 7 with the bristles on the cleaning cylinder 31. During movement, the moving plate 29 uses gear 34 to roll on the fixing bar 35, causing the cleaning cylinder 31 and the bristles to rotate as a whole, resulting in a more thorough cleaning of the filter screen 7. After cleaning, the filter screen 7 is stored in the storage frame 17. When the ship is sailing on the sea, the rotating wheel 48 in the fixing frame 46 rotates the threaded rod 47, causing the locking disc 19 to move away from the transformer box 2, releasing the locking mechanism on the transformer box 2. When the ship sways, the transformer box 2 and the transformer body 3 will sway as a whole. During this process, the counterweight 39 and the sleeve 38 will sway in the corresponding direction of the fixed column 37. Under the action of the teeth on the sleeve 38 and the swaying seat 36, the transformer box 2 will rotate in the opposite direction to buffer the sway. The guide plate 44 on the transformer box 2 slides on the guide seat 43 to increase the stability during anti-swaying. The buffer sleeve 40 and the spring 41 on the fixed column 37 will buffer the sleeve 38 to prevent the sleeve 38 from directly hitting the support frame 1 and generating noise. The structure is simple and the function is practical.

[0022] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
