Description

[0001] This application is a divisional application of the application with the application number 2025100414857, the application date of January 10, 2025, and the invention title of "A Marine Transformer with a Protection Mechanism". Technical Field

[0002] The present invention relates to the technical field of marine transformers, and particularly to a protection structure for a marine transformer. Background Art

[0003] A marine transformer is a power device specially designed for ships, mainly used to adjust the voltage generated by ship generators to a voltage suitable for various electrical equipment on board; marine transformers have the characteristics of being resistant to humidity, salt spray, mildew, and being not afraid of impact, vibration, tilt, and sway, and are usually designed as a sealed structure to adapt to the ship environment. In the existing marine transformers, when the hull is tilted under the influence of wind and waves, the transformer oil tank can be driven to tilt synchronously. The transformer oil inside the transformer oil tank flows along the tilting direction of the transformer oil tank. At this time, the sliding component drives the flow blocking component to move in the direction opposite to the tilting direction of the transformer oil tank. When the flow blocking component moves, it can push the flowing transformer oil, thereby reducing the impact force of the transformer oil on the inner wall of the transformer oil tank and avoiding excessive impact force of the transformer oil on the transformer oil tank, which may cause deformation and damage to the transformer oil tank. However, when the ship is traveling on the water surface, not only will it tilt left and right and front, but the oil in the transformer oil tank will impact the inner side wall of the transformer oil tank. Moreover, as the water surface undulates, the hull will slide up and down on the water surface. In this way, the oil in the transformer oil tank will slide up and down, causing impact on the upper and lower inner walls of the transformer oil tank, especially a large impact force on the lower inner wall of the transformer oil tank, and the lower inner wall of the transformer oil tank is prone to deformation. Therefore, there are areas for improvement. Summary of the Invention

[0012] The following is further described in detail in conjunction with the attached Figures 1 - 8 drawings of the present invention.

[0013] An embodiment of the present invention discloses a marine transformer with a protection mechanism, including a transformer oil tank 1 and a mounting seat 2. The transformer oil tank 1 is arranged above the mounting seat 2. A moving support structure is arranged in the middle of the upper surface of the mounting seat 2. The transformer oil tank 1 is arranged on the mounting seat 2 through an external protection structure. A mounting frame 31 is fastened in the middle of the lower inner wall of the transformer oil tank 1. A winding 32 is installed on the mounting frame 31. Internal protection structures are arranged on the upper and lower inner walls of the transformer oil tank 1. Side protection structures are arranged on the left and right sides of the lower inner wall of the transformer oil tank 1; The internal protection structure includes a fixing strip 3 fixedly installed in the middle of the inner walls on the upper and lower sides of the transformer oil tank 1. First grooves 4 are provided at positions near both ends of the fixing strip 3. A first fixing rod 8 is connected between the two end walls of each first groove 4. A first moving block 5 is movably sleeved at one end of the first fixing rod 8. The first moving block 5 is slidably arranged in the first groove 4. A first spring 9 is sleeved on the first fixing rod 8. The two ends of the first spring 9 are respectively connected to the first moving block 5 and one end wall of the first groove 4. The top end of the first moving block 5 is rotatably connected to a first curved plate 6. One end of the first curved plate 6 is rotatably connected to a mounting plate 7. A plurality of first protection plates 10 are equidistantly installed on one side of the mounting plate 7 away from the fixing strip 3. The side of the first protection plate 10 close to the winding 32 is a concave arc surface. When the hull sways up and down during water travel, driving the oil in the transformer oil tank 1 to sway up and down, the flow of the oil is blocked by a plurality of first protection plates 10 on the inner walls of the upper and lower sides of the transformer oil tank 1. And the first protection plate 10 drives one end of the first curved plate 6, the first moving block 5 to move in the first groove 4, driving the deformation of the first spring 9, so as to buffer and protect the oil, reducing the impact of the oil on the inner walls of the upper and lower sides of the transformer oil tank 1, and preventing the problem that the upper and lower sides of the transformer oil tank 1 are deformed.

[0014] See Figures 1 - 3 , the external protection structure includes fixing blocks 14 fixedly arranged at the four corner positions on the upper surface of the mounting base 2. The fixing blocks 14 are in a "cross" shape. A vertical rod is connected to the middle of the upper surface of the fixing block 14. A sleeve 11 is movably sleeved on the vertical rod. A welding plate 13 is fastened to the top end of the sleeve 11 by bolts. The welding plate 13 is welded to the transformer oil tank 1. A second spring 12 is sleeved on the vertical rod. The two ends of the second spring 12 are respectively connected to the fixing block 14 and the bottom end of the sleeve 11. An auxiliary protection structure is arranged on the fixing block 14. When the hull slides up and down, outside the transformer oil tank 1, it drives the sleeve 11 to move up and down on the vertical rod, driving the deformation of the second spring 12, so as to buffer and protect outside the transformer oil tank 1, further improving the protection effect on the upper and lower sides of the transformer oil tank 1; The auxiliary protection structure includes four second grooves 16 opened on the upper surface of the fixed block 14. A second moving block 17 is slidably arranged at the groove wall of one end of the second groove 16 close to the sleeve 11. A first T-shaped rod 18 that movably passes through the fixed block 14 is connected to one side surface of the second moving block 17. A third spring 19 is sleeved on the first T-shaped rod 18. Two ends of the third spring 19 are respectively connected to one end of the first T-shaped rod 18 and the outer side surface of the fixed block 14. The top end of the second moving block 17 is rotatably connected to a second curved plate 15. The top end of the second curved plate 15 is rotatably connected to the welding plate 13. When the sleeve 11 moves on the vertical rod, the second moving block 17 and the first T-shaped rod 18 as a whole are driven to move on the fixed block 14 through the second curved plate 15, driving the third spring 19 to deform, so as to convert part of the vertical impact force into transverse buffer protection, and the protection quality is higher.

[0015] See Figure 2 and Figure 4 , the moving support structure includes a fixed frame 20 fixedly installed at the middle of the upper surface of the mounting seat 2. Third grooves 21 are opened at the lower parts of the front and rear inner walls of the fixed frame 20. A third moving block 22 is slidably arranged in the third grooves 21. Fourth grooves 23 are opened at the upper parts of the left and right inner walls of the fixed frame 20. A fourth moving block 24 is slidably arranged in the fourth grooves 23. Slide rods 25 are respectively connected between the two fourth moving blocks 24 and between the two third moving blocks 22. A moving seat 26 is movably sleeved on the two slide rods 25. A support plate 27 is installed at the middle of the upper surface of the moving seat 26. When the hull tilts, the center of gravity of the transformer oil tank 1 shifts. At this time, by using the movement of the moving seat 26 on the fixed frame 20, the support plate 27 is driven to move to the corresponding position below the transformer oil tank 1 to perform auxiliary support work, reducing the problem that the vertical rod breaks due to excessive shaking force, and improving the installation firmness of the transformer oil tank 1 on the mounting seat 2.

[0016] See Figure 1 , the side protection structure includes switching seats 28 respectively rotatably installed at the positions close to the four corners of the lower inner wall of the transformer oil tank 1. A gear 30 is fixedly sleeved at the bottom end of the switching seat 28. A second protection plate 29 is installed at the top end of the switching seat 28. One side surface of the second protection plate 29 is a concave arc surface. Switching structures are arranged at the left and right sides of the lower inner wall of the transformer oil tank 1; The switching structure includes two cross plates 33 installed at the left and right sides of the lower inner wall of the transformer oil tank 1. Guide grooves 34 are opened at the middle of the front and rear side surfaces of the cross plates 33. A sliding seat 35 is sleeved on the guide grooves 34. A gravity block 36 is installed at the middle of the upper surface of the sliding seat 35. Driving strips 37 are respectively connected to the front and rear side edges of the lower surface of the sliding seat 35. Teeth meshing with the gear 30 are arranged on the driving strips 37. A limiting structure is arranged on the cross plates 33; The limiting structure is a limiting block 38 arranged at positions near both ends in the guiding groove 34. A through hole 39 is formed in the middle of the limiting block 38. Second fixing rods 40 are connected to the positions of the left and right side surfaces of the sliding seat 35 that are inside the guiding groove 34. Second T-shaped rods 42 are movably inserted through the left and right end walls of the guiding groove 34. A fourth spring 43 is sleeved on the second T-shaped rod 42. The two ends of the fourth spring 43 are respectively connected to one end of the second T-shaped rod 42 and the cross plate 33. A pushing block 41 is installed at the end of the second T-shaped rod 42 inserted into the guiding groove 34. When the hull tilts, under the action of the gravity of the gravity block 36, the sliding seat 35 is driven to move on the cross plate 33 towards the tilted side of the hull. Through the driving strip 37 and the gear 30, the switching seat 28 and the second protection plate 29 are driven to rotate integrally, so that the concave arc surface on the second protection plate 29 is switched to the opposite direction of the hull tilt, to block the flowing oil in the transformer oil tank 1, thereby reducing the problem that the side of the transformer oil tank 1 is deformed due to the impact of the oil sloshing. Moreover, when the sliding seat 35 moves, due to the limiting effect of the limiting block 38 on the sliding seat 35, the second protection plate 29 remains stationary after switching, thus ensuring the protection quality of the second protection plate 29. And the movement of the sliding seat 35 drives the second fixing rod 40 to move onto the pushing block 41, pushing the second T-shaped rod 42 to move and stretching the fourth spring 43, to reduce the noise generated when the sliding seat 35 impacts the limiting block 38.

[0017] The implementation principle of a marine transformer with a protection mechanism in an embodiment of the present invention is as follows: First, the transformer oil tank 1 is fixedly installed on the hull through the mounting base 2. When the hull shakes up and down during navigation, driving the oil in the transformer oil tank 1 to shake up and down, multiple first protection plates 10 at the inner walls on both the upper and lower sides of the transformer oil tank 1 are used to block the flow. And the first protection plates 10 drive the first moving block 5 at one end of the first curved plate 6 to move in the first groove 4, driving the deformation of the first spring 9 to buffer and protect the oil, reducing the impact of the oil on the inner walls on both the upper and lower sides of the transformer oil tank 1 for protection. Moreover, outside the transformer oil tank 1, it drives the bushing 11 to move up and down on the vertical rod, driving the deformation of the second spring 12, thereby buffering and protecting outside the transformer oil tank 1. At the same time, the movement of the bushing 11 on the vertical rod drives the second moving block 17 and the first T-shaped rod 18 as a whole to move on the fixed block 14 through the second curved plate 15, driving the deformation of the third spring 19, thereby converting part of the vertical impact force into a lateral buffer protection with higher protection quality. When the hull tilts left and right, under the gravity of the gravity block 36, it drives the sliding seat 35 to move on the cross plate 33 towards the tilted side of the hull. Through the driving strip 37 and the gear 30, it drives the switching seat 28 and the second protection plate 29 as a whole to rotate, so that the concave arc surface on the second protection plate 29 is switched to the opposite direction of the hull tilt to block the flowing oil in the transformer oil tank 1, thereby reducing the problem that the oil sloshing impacts the side of the transformer oil tank 1 and causes deformation, providing more comprehensive protection. And when the sliding seat 35 moves, due to the limiting effect of the limiting block 38 on the sliding seat 35, the second protection plate 29 remains stationary after switching, thus ensuring the protection quality of the second protection plate 29. Moreover, the movement of the sliding seat 35 drives the second fixed rod 40 to move onto the pushing block 41, pushing the second T-shaped rod 42 to move and stretch the fourth spring 43 to reduce the noise generated when the sliding seat 35 impacts the limiting block 38. At the same time, using the movement of the moving seat 26 on the fixed frame 20, it drives the support plate 27 to move to the corresponding position below the transformer oil tank 1 to perform auxiliary support work, reducing the problem that the vertical rod breaks due to excessive shaking force and improving the installation firmness of the transformer oil tank 1 on the mounting base 2. The structure is simple and the function is practical.

[0018] The above are all preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
