The second guide column 41 is sleeved with a second compression spring 43 on the outside, and the two ends of the second compression spring 43 are respectively in contact with the first side plate 5 and the fixed plate 42;

[0035] The first servo motor 16 is started, and the first servo motor 16 drives the first rotating shaft 15 and the first bevel gear 20 to rotate. The first bevel gear 20 drives the second rotating shaft 21 and the fan blade 22 to rotate through the second bevel gear 67, so that the air in the sealed space composed of the loading platform 1, the top plate 3, the two first side plates 5 and the two second side plates 6 is dried by the desiccant 14 in the air permeable box 13 to reduce the humidity of the air in the sealed space. When the synchronous unfolding component drives the first side plate 5 and the second side plate 6 to rotate, so that the first side plate 5 and the second side plate 6 are unfolded, the second servo motor 45 drives the third connecting shaft 46 and the first winding wheel 47 to rotate, so that the first connecting rope 48 is wound around the outside of the first winding wheel 47, and the first connecting rope 48 drives the first connecting plate 4 4 moves upward relative to the first control box 31 and the movable plate 9. When the first connecting rope 48 pulls the first connecting plate 44, the first connecting rope 48 is guided by the first guide wheel 49, and the position of the first connecting rope 48 is limited by the first anti-slip plate 50 to prevent the first connecting rope 48 from sliding off the first guide wheel 49.

As the second gear 33 rotates, the second gear 33 rolls on the second tooth plate 34, so that the second gear 33 , the first connecting shaft 32, the first control box 31 and the movable plate 9 move relative to the first side plate 5, and the movable plate 9 drives the second guide column 41 and the fixed plate 42 to move, the second compression spring 43 is in a compressed state, and at the same time the first connecting shaft 32 drives the second damping plate 40 to rotate, the second damping plate 40 drives the first damping plate 39 and the second connecting shaft 37 to rotate by friction, the second connecting shaft 37 drives the rotating plate 11 to rotate so that the rectangular hole 10 is opened, when the rotating plate 11 contacts the second stop plate 69, as the second damping plate 40 continues to rotate, the second damping plate 40 cannot drive the first damping plate 39 and the second connecting shaft 37 to rotate by friction, so that the rotating plate 11 automatically stops after rotating to a preset position, and the first compression spring 30 is in an initial state In the compressed state, the first compression spring 30 applies pressure to the first fixed plate 27, and the first fixed plate 27 and the first stop plate 28 are in close contact, so that the first fixed plate 27 and the first toothed plate 26 are stationary relative to the first stop plate 28 and the first side plate 5. Since the movable plate 9 moves relative to the first side plate 5, the movable plate 9 drives the rotating cylinder 12 to move synchronously through the support plate 24, so that the first gear 25 rolls on the first toothed plate 26, and the first gear 25, the third rotating shaft 23 and the rotating cylinder 12 can be rotated relative to the support plate 24. Since the axis of the third rotating shaft 23 and the first rotating shaft 15 are consistent, the rotating cylinder 12 rotates synchronously around the first rotating shaft 15, and the second bevel gear 67 in the transmission box 18 rolls on the first bevel gear 20. After the rotating cylinder 12 rotates one hundred and eighty degrees,The air box 13 faces the rectangular hole 10, and at this time the air box 13 is in contact with the stop frame 68, the air box 13 is stationary relative to the stop frame 68 and the movable plate 9, as the movable plate 9 continues to move, the first gear 25 drives the first gear plate 26 to move synchronously with the rotating cylinder 12 and the movable plate 9, the first fixed plate 27 slides relative to the first guide column 29, the length of the first compression spring 30 becomes smaller, as the rotating cylinder 12 and the air box 13 continue to move, the air box 13 extends out through the avoidance hole 8, when the first side plate 5 is unfolded, the movable plate 9 The second servo motor 45 drives the first winding wheel 47 to rotate in the opposite direction, thereby reducing the length of the first connecting rope 48 wound around the first winding wheel 47. The second compression spring 43 drives the fixed plate 42, the second guide column 41 and the movable plate 9 to rotate in the opposite direction. The second gear 33 rolls in the opposite direction on the second tooth plate 34, and the second gear 33 drives the third tooth plate 38 and the first connecting plate 44 to move in the opposite direction. Finally, the movable plate 9 contacts the first side plate 5 again, and the rotating plate 11 rotates in the opposite direction relative to the movable plate 9 to the initial position, and the rotating plate 11 contacts the movable plate 9 again, and the rotating plate 11 seals the rectangular hole 10, and the movable plate 9 seals the avoidance hole 8. During the sliding process of the movable plate 9 relative to the first side plate 5, the movable plate 9 drives the rotating cylinder 12 in the opposite direction through the supporting plate 24. The first compression spring 30 pushes the first fixed plate 27 to move synchronously, so that the first toothed plate 26 and the first fixed plate 27 move synchronously with the first gear 25. When the first fixed plate 27 contacts the first stop plate 28, as the movable plate 9 and the rotating cylinder 12 continue to move, the first toothed plate 26 remains stationary, and the first gear 25 rolls in the opposite direction on the first toothed plate 26. Finally, the movable plate 9 contacts the first side plate 5. At this time, the rotating cylinder 12 rotates 180 degrees in the opposite direction, and the air box 13 faces the dry-type transformer body 2 again.

[0037] When the second servo motor 45 drives the third connecting shaft 46 to rotate, the third connecting shaft 46 synchronously drives the second winding wheel 52 to rotate, and the second winding wheel 52 pulls the second connecting plate 60 and the fourth tooth plate 57 to move relative to the second control box 55 through the second connecting rope 61, and the second guide plate 59 slides in the second guide groove 58. The design of the second guide plate 59 and the second guide groove 58 allows the fourth tooth plate 57 to move smoothly relative to the second control box 55, and the fourth tooth plate 57 drives the third gear 56, the support shaft 54 ​​and the second fixed plate 53 to rotate, and the second fixed plate 53 can drive the corresponding first side plate 5 or the second side plate 6 to rotate relative to the second control box 55 and the top plate 3, and the first side plate 5 and The second side plate 6 drives the corresponding iron plate 65 to move, and the iron plate 65 is no longer magnetically attracted to the magnet block 66, so that several first side plates 5 and second side plates 6 can be synchronously unfolded.

[0038] Working principle: When working, a sealed space is formed by the stage 1, the top plate 3, the two first side plates 5 and the two second side plates 6. When the humidity in the air is higher than the preset value, the air in the sealed space is dried by the circulating drying structure. When it is rainy or snowy, the dry-type transformer body 2 is protected by the formed sealed space to reduce the possibility of the dry-type transformer body 2 getting damp. When it is not rainy or snowy, the first side plate 5 and the second side plate 6 are driven to rotate by the synchronous unfolding component, so that the first side plate 5 and the second side plate 6 are unfolded to avoid the dry-type transformer body 2 being in the sealed space, which is convenient for heat dissipation of the dry-type transformer body 2. At the same time, the solar panel 7 faces the sky, and the solar panel 7 converts sunlight into electrical energy to power some electrical components on the photovoltaic dry-type transformer;

[0039] The first servo motor 16 is started, and the first servo motor 16 drives the first rotating shaft 15 and the first bevel gear 20 to rotate. The first bevel gear 20 drives the second rotating shaft 21 and the fan blade 22 to rotate through the second bevel gear 67, so that the air in the sealed space composed of the loading platform 1, the top plate 3, the two first side plates 5 and the two second side plates 6 is dried by the desiccant 14 in the air permeable box 13 to reduce the humidity of the air in the sealed space. When the synchronous unfolding component drives the first side plate 5 and the second side plate 6 to rotate, so that the first side plate 5 and the second side plate 6 are unfolded, the second servo motor 45 drives the third connecting shaft 46 and the first winding wheel 47 to rotate, so that the first connecting rope 48 is wound around the outside of the first winding wheel 47, and the first connecting rope 48 drives the first connecting plate 4 4 moves upward relative to the first control box 31 and the movable plate 9. When the first connecting rope 48 pulls the first connecting plate 44, the first connecting rope 48 is guided by the first guide wheel 49, and the position of the first connecting rope 48 is limited by the first anti-slip plate 50 to prevent the first connecting rope 48 from sliding off the first guide wheel 49. When the first connecting plate 44 moves, the first connecting plate 44 drives the second gear 33 and the first connecting shaft 32 to rotate through the third tooth plate 38, and the first guide plate 36 slides in the first guide groove 35. The design of the first guide groove 35 and the first guide plate 36 allows the third tooth plate 38 to move smoothly relative to the first control box 31. As the second gear 33 rotates, the second gear 33 rolls on the second tooth plate 34, so that the second gear 33 , the first connecting shaft 32, the first control box 31 and the movable plate 9 move relative to the first side plate 5, and the movable plate 9 drives the second guide column 41 and the fixed plate 42 to move, the second compression spring 43 is in a compressed state, and at the same time the first connecting shaft 32 drives the second damping plate 40 to rotate, the second damping plate 40 drives the first damping plate 39 and the second connecting shaft 37 to rotate by friction, the second connecting shaft 37 drives the rotating plate 11 to rotate so that the rectangular hole 10 is opened, when the rotating plate 11 contacts the second stop plate 69, as the second damping plate 40 continues to rotate, the second damping plate 40 cannot drive the first damping plate 39 and the second connecting shaft 37 to rotate by friction, so that the rotating plate 11 automatically stops after rotating to a preset position, and the first compression spring 30 is in an initial state In the compressed state, the first compression spring 30 applies pressure to the first fixed plate 27, and the first fixed plate 27 and the first stop plate 28 are in close contact, so that the first fixed plate 27 and the first toothed plate 26 are stationary relative to the first stop plate 28 and the first side plate 5. Since the movable plate 9 moves relative to the first side plate 5, the movable plate 9 drives the rotating cylinder 12 to move synchronously through the support plate 24, so that the first gear 25 rolls on the first toothed plate 26, and the first gear 25, the third rotating shaft 23 and the rotating cylinder 12 can be rotated relative to the support plate 24. Since the axis of the third rotating shaft 23 and the first rotating shaft 15 are consistent, the rotating cylinder 12 rotates synchronously around the first rotating shaft 15, and the second bevel gear 67 in the transmission box 18 rolls on the first bevel gear 20. After the rotating cylinder 12 rotates one hundred and eighty degrees,The air box 13 faces the rectangular hole 10, and at this time the air box 13 is in contact with the stop frame 68, the air box 13 is stationary relative to the stop frame 68 and the movable plate 9, as the movable plate 9 continues to move, the first gear 25 drives the first gear plate 26 to move synchronously with the rotating cylinder 12 and the movable plate 9, the first fixed plate 27 slides relative to the first guide column 29, the length of the first compression spring 30 becomes smaller, as the rotating cylinder 12 and the air box 13 continue to move, the air box 13 extends out through the avoidance hole 8, when the first side plate 5 is unfolded, the movable plate 9 is in The first side plate 5 is placed above the first side plate 5. At this time, the air box 13 faces the sky. The sunlight can dry the desiccant 14 in the air box 13 to reduce the moisture in the desiccant 14. When the stage 1, the top plate 3, the two first side plates 5 and the two second side plates 6 form a sealed space again, the second servo motor 45 drives the first winding wheel 47 to rotate in the opposite direction to reduce the length of the first connecting rope 48 wound around the outside of the first winding wheel 47. The second compression spring 43 drives the fixed plate 42, the second guide column 41 and the movable plate 9 to rotate in the opposite direction. The second gear 33 rolls in the opposite direction on the second tooth plate 34, and the second gear 33 drives the third tooth plate 38 and the first connecting plate 44 to move in the opposite direction. Finally, the movable plate 9 contacts the first side plate 5 again, and the rotating plate 11 rotates in the opposite direction relative to the movable plate 9 to the initial position, and the rotating plate 11 contacts the movable plate 9 again, and the rotating plate 11 seals the rectangular hole 10, and the movable plate 9 seals the avoidance hole 8. During the sliding process of the movable plate 9 relative to the first side plate 5, the movable plate 9 drives the rotating cylinder 12 to move in the opposite direction through the supporting plate 24. The first compression spring 30 pushes the first fixed plate 27 to move synchronously, so that the first toothed plate 26 and the first fixed plate 27 move synchronously with the first gear 25. When the first fixed plate 27 contacts the first stop plate 28, as the movable plate 9 and the rotating cylinder 12 continue to move, the first toothed plate 26 remains stationary, and the first gear 25 rolls in the opposite direction on the first toothed plate 26. Finally, the movable plate 9 contacts the first side plate 5. At this time, the rotating cylinder 12 rotates 180 degrees in the opposite direction, and the air box 13 faces the dry-type transformer body 2 again;

[0040] When the second servo motor 45 drives the third connecting shaft 46 to rotate, the third connecting shaft 46 synchronously drives the second winding wheel 52 to rotate, and the second winding wheel 52 pulls the second connecting plate 60 and the fourth tooth plate 57 to move relative to the second control box 55 through the second connecting rope 61, and the second guide plate 59 slides in the second guide groove 58. The design of the second guide plate 59 and the second guide groove 58 allows the fourth tooth plate 57 to move smoothly relative to the second control box 55, and the fourth tooth plate 57 drives the third gear 56, the support shaft 54 ​​and the second fixed plate 53 to rotate, and the second fixed plate 53 can drive the corresponding first side plate 5 or the second side plate 6 to rotate relative to the second control box 55 and the top plate 3, and the first side plate 5 and The second side plate 6 drives the corresponding iron plate 65 to move, and the iron plate 65 is no longer magnetically attracted to the magnet block 66, so that several first side plates 5 and second side plates 6 can be synchronously unfolded. When the second servo motor 45 drives the third connecting shaft 46 to rotate in the opposite direction, the first side plate 5 and the second side plate 6 rotate in the opposite direction to the initial position, and the iron plate 65 and the magnet block 66 are magnetically attracted together to prevent the first side plate 5 and the second side plate 6 from rotating and shaking relative to the top plate 3.
