[0029] The internal protection structure comprises a fixed strip 3 fixedly installed at the middle of the inner wall of the upper and lower sides of the transformer oil tank 1, a first recess 4 is formed at the position close to the two ends of the fixed strip 3, a first fixed rod 8 is connected between the two end groove walls of each first recess 4, a first moving block 5 is movably sleeved at one end of the first fixed rod 8, the first moving block 5 is slidably arranged in the first recess 4, a first spring 9 is sleeved on the first fixed rod 8, the two ends of the first spring 9 are connected to the first moving block 5 and one end groove wall of the first recess 4 respectively, a first curved plate 6 is rotatably connected to the top end of the first moving block 5, 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 mounted on the side of the mounting plate 7 away from the fixed strip 3, the side of the first protection plate 10 close to the winding 32 is a concave arc surface, when the ship body swings up and down on the water surface, the oil liquid in the transformer oil tank 1 also swings up and down, the flow is blocked by the plurality of first protection plates 10 at the upper and lower inner walls of the transformer oil tank 1, and the first protection plate 10 drives the first moving block 5 at one end of the first curved plate 6 to move in the first recess 4, drives the deformation of the first spring 9, to buffer and protect the oil liquid, reduce the impact of the oil liquid on the upper and lower inner walls of the transformer oil tank 1, and cause the deformation of the upper and lower sides of the transformer oil tank 1.

[0030] Referring to Figures 1-3 The external protection structure comprises a fixed block 14 fixedly arranged at the four corner positions on the upper surface of the mounting seat 2, the fixed block 14 is in the shape of a cross, a vertical rod is connected to the middle of the upper surface of the fixed block 14, a sleeve pipe 11 is movably sleeved on the vertical rod, a welding disc 13 is fastened on the top end of the sleeve pipe 11 through bolts, the welding disc 13 is welded on the transformer oil tank 1, a second spring 12 is sleeved on the vertical rod, the two ends of the second spring 12 are connected to the fixed block 14 and the bottom end of the sleeve pipe 11 respectively, an auxiliary protection structure is arranged on the fixed block 14, when the ship body slides up and down, the sleeve pipe 11 moves up and down on the vertical rod outside the transformer oil tank 1, drives the deformation of the second spring 12, thereby buffering and protecting outside the transformer oil tank 1, further improving the protection effect of the upper and lower sides of the transformer oil tank 1;

[0031] The auxiliary protective structure includes four second grooves 16 formed on the fixed block 14. A second moving block 17 is slidably disposed on the groove wall of one end of the second groove 16 near the sleeve 11.

A second curved plate 15 is rotatably connected to the top of the second moving block 17. The top 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 move together on the fixed block 14 through the second curved plate 15, causing the third spring 19 to deform, thereby converting part of the vertical impact force into lateral buffer protection, resulting in higher protection quality.

[0032] See Figure 2 and Figure 4 The movable support structure includes a fixed frame 20 fixedly installed in the middle of the mounting base 2. A third groove 21 is provided on the lower part of the inner walls on both the front and rear sides of the fixed frame 20. A third moving block 22 is slidably disposed in the third groove 21. A fourth groove 23 is provided on the upper part of the inner walls on both the left and right sides of the fixed frame 20. A fourth moving block 24 is slidably disposed in the fourth groove 23. A sliding rod 25 is connected between the two fourth moving blocks 24 and between the two third moving blocks 22. A movable seat 26 is movably sleeved on the two sliding rods 25. A support plate 27 is installed in the middle of the upper part of the movable seat 26. When the hull tilts, the center of gravity of the transformer tank 1 shifts. At this time, by using the movement of the movable seat 26 on the fixed frame 20, the support plate 27 is moved to the corresponding position below the transformer tank 1 to provide auxiliary support, reducing the problem of the vertical rod breaking due to excessive shaking force and improving the installation stability of the transformer tank 1 on the mounting base 2.

[0033] See Figure 1 The side protection structure includes a switching seat 28 that is rotatably installed on the lower inner wall of the transformer tank 1 near the four corners. A gear 30 is fixedly sleeved on the bottom end of the switching seat 28. A second protective plate 29 is installed on the top end of the switching seat 28. One side of the second protective plate 29 is a concave arc surface. Switching structures are provided on both the left and right sides of the lower inner wall of the transformer tank 1.

[0034] The switching structure includes two horizontal plates 33 installed on the left and right sides of the lower inner wall of the transformer oil tank 1. Guide grooves 34 are provided in the middle of the front and rear sides of the horizontal plates 33. A slide block 35 is fitted on the guide groove 34. A gravity block 36 is installed in the middle of the upper part of the slide block 35. A drive bar 37 is connected to the front and rear edges of the slide block 35. The drive bar 37 is provided with teeth that mesh with the gear 30. A limit structure is provided on the horizontal plates 33.

[0035] The limiting structure is set in the guide groove 34 near the two ends of the limiting block 38. The limiting block 38 has a through hole 39 in the middle. The left and right sides of the slide 35 are connected to the second fixing rod 40 in the guide groove 34. The left and right end walls of the guide groove 34 are movably connected to the second T-shaped rod 42. The second T-shaped rod 42 is fitted with a fourth spring 43. 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. The end of the second T-shaped rod 42 inserted into the guide groove 34 is equipped with a push block 41. When the hull tilts, under the gravity of the gravity block 36, the slide 35 is driven to move on the cross plate 33 towards the tilted side of the hull. This is achieved by the drive bar 37 and the tooth. Wheel 30 drives the switching seat 28 and the second protective plate 29 to rotate as a whole, so that the concave arc surface on the second protective plate 29 switches to the opposite direction of the hull tilt, thereby blocking the flow of oil sliding in the transformer oil tank 1, thus reducing the oil sloshing impact on the side of the transformer oil tank 1 and causing deformation. When the slide 35 moves, the limiting block 38 limits the slide 35, so that the second protective plate 29 remains in the same position after switching, thus ensuring the protection quality of the second protective plate 29. The movement of the slide 35 drives the second fixed rod 40 to move onto the push block 41, pushing the second T-shaped rod 42 to move and stretch the fourth spring 43, thereby reducing the noise generated when the slide 35 hits the limiting block 38.

[0036] The implementation principle of a marine transformer with a protective mechanism according to an embodiment of the present invention is as follows: First, the transformer tank 1 is fixedly installed on the hull by the mounting base 2. During the voyage, the hull sways up and down, causing the oil in the transformer tank 1 to sway up and down. Multiple first protective plates 10 on the inner walls of the upper and lower sides of the transformer tank 1 impede the flow. Furthermore, the first protective plates 10 cause the first moving block 5 at one end of the first curved plate 6 to move within the first groove 4, causing the first spring 9 to deform, thereby buffering and protecting the oil and reducing the impact of the oil on the inner walls of the upper and lower sides of the transformer tank 1. The sleeve 11 moves up and down on the vertical rod outside the transformer tank 1, causing the second spring 12 to deform, thus providing buffer protection outside the transformer tank 1. Simultaneously, the movement of the sleeve 11 on the vertical rod, via the second curved plate 15, causes the second moving block 17 and the first T-shaped rod 18 to move together on the fixed block 14, causing the third spring 19 to deform, thereby converting part of the vertical impact force into lateral buffer protection, resulting in higher protection quality. When the hull tilts left or right, under the gravity of the gravity block 36, the sliding block 35 is moved... The horizontal plate 33 moves towards the side tilted towards the hull, driving the switch seat 28 and the second protective plate 29 to rotate as a whole via the drive bar 37 and gear 30. This causes the concave arc surface on the second protective plate 29 to switch to the opposite direction of the hull's tilt, thus obstructing the flow of sliding oil in the transformer tank 1. This reduces the impact of oil sloshing on the side of the transformer tank 1, preventing deformation and providing more comprehensive protection. Furthermore, when the slide 35 moves, the limiting block 38 limits its position, ensuring that the second protective plate 29 remains stationary after switching, thereby guaranteeing the protection of the second protective plate 29. The slide block 35 provides a high level of protection, and its movement causes the second fixed rod 40 to move onto the push block 41, which in turn moves the second T-shaped rod 42 to stretch the fourth spring 43, thereby reducing the noise generated when the slide block 35 hits the limit block 38. At the same time, the movement of the movable seat 26 on the fixed frame 20 causes the support plate 27 to move to the corresponding position below the transformer tank 1 to provide auxiliary support, reducing the problem of the vertical rod breaking due to excessive shaking force, and improving the installation firmness of the transformer tank 1 on the mounting base 2. The structure is simple and the function is practical.

[0037] 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.
