More specifically, by driving the servo motor 31, the first screw rod 33 drives the second sprocket wheel set at the bottom of the second screw rod to rotate through the action of the first sprocket wheel 38 and the chain 39 set at the bottom, so that the first screw rod and the second screw rod 33 rotate synchronously to drive the movable block 34 set at the middle position to move up and down. While the movable block 34 moves up and down, the protective plate 32 rotatably installed on one side of the support plate 30 is rotated to adjust the angle through the action between the first connecting seat 35, the movable rod 36 and the second connecting seat 37, so that the protective effect of the protective plate 32 on the heat dissipation fins 3 is optimized, thereby improving the protection performance.

[0020] refer to Figure 8 , Fig. 9The heat dissipation mechanism includes a mounting tube 40 mounted on the transformer body 2, a fixing ring 41 is provided at one end of the mounting tube 40, a cross fixing frame 43 is fixedly installed in the mounting tube 40, a cooling fan 44 is installed on the cross fixing frame 43, a locking assembly for locking and fixing the dustproof net 42 is installed on the mounting tube 40, and the locking assembly includes a sleeve 45 installed on the outer wall of the mounting tube 40, a pulling rod 46 is provided in the sleeve 45, one end of the pulling rod 46 is fixedly installed between a circular block 47, a spring 48 is provided at a section of the pulling rod 46, one end of the spring 48 is connected to the circular block 47, and the other end is fixedly connected to the inner wall of the sleeve 45, a locking flange 49 is provided at one end of the circular block 47, and the locking flange 49 is inserted into the corresponding fixed opening on the outer wall of the dustproof net 42 In the hole, more specifically, the mounting tube 40 is fixedly mounted in the through holes opened in the side walls at both ends of the transformer body 2 by means of a fixing ring 41 and bolts arranged on one side. When the heat inside the transformer body 2 is too high, the cooling fan 44 installed inside the mounting tube 40 is driven to cool the interior, thereby improving the heat dissipation effect of the transformer body 2. At the same time, the pull rod 46 passing through the sleeve 45 arranged on the outer wall of the mounting tube 40 is pulled, so that the pull rod 46 drives the circular block 47 to squeeze the spring 48 connected on one side, so that the circular block 47 slides along the inside of the mounting tube 40 and drives the locking flange 49 arranged on the other side to overflow the through hole opened in the outer wall of the dustproof net 42 arranged at one end of the mounting tube 40, so that the dustproof net 42 can be disassembled for cleaning to prevent dust from accumulating on the dustproof net 42, thereby improving the ventilation effect and thus improving the heat dissipation effect.

[0021] The implementation principle of a transformer with a lightning protection structure in an embodiment of the present invention is as follows: when the raindrop sensor does not detect rain, the first motor 4 works, causing the small gear 5 to rotate counterclockwise to drive the large gear 6 to rotate, and the rotation of the large gear 6 drives the rotating seat 7 to rotate, thereby driving the lightning rod 9 fixed on the top to rotate into the protective cover 26 set on the top of the transformer body 2, and at the same time, the transmission shaft causes the large transmission wheel 22 installed at one end to drive the small transmission wheel 20 to rotate counterclockwise through the transmission belt 21, so that the bidirectional screw rod 24 rotates between the two support blocks 23, and drives the two protective covers 26 through the bottom set The guide block 27 slides toward each other along the guide rod 29, and the lightning rod 9 is covered inside to protect it and increase the service life of the lightning rod 9. When the raindrop sensor detects rain, the first motor 4 works, so that the small gear 5 rotates clockwise to drive the large gear 6 to rotate, so that the rotating seat 7 drives the lightning rod 9 fixed on the top to rotate from the inside of the protective cover 26, and the two protective covers 26 expand outward synchronously. When the lightning rod 9 rotates to be perpendicular to the transformer body 1, the electric push rod 11 is driven to drive the clamping convex tooth 12 to move forward and insert it into the corresponding tooth groove on the large gear 6, thereby The first sprocket 38 and the second sprocket 39 are used to drive the first screw rod 33 to rotate, so that the second sprocket provided at the bottom of the second screw rod 3 is driven to rotate. The first screw rod and the second screw rod 33 are driven to rotate synchronously to drive the movable block 34 to move up and down. When the movable block 34 moves up and down, the protective plate 32 installed on one side of the support plate 30 is rotated to adjust the angle through the action between the first connecting seat 35, the movable rod 36 and the second connecting seat 37, so that the protective plate 32 can protect the heat dissipation fins 3. The protection effect is optimal. When the heat inside the transformer body 2 is too high, the cooling fan 44 installed inside the mounting tube 40 is driven to cool the interior, so that the heat dissipation effect of the transformer body 2 is improved. At the same time, the pull rod 46 passing through the sleeve 45 is pulled, so that the pull rod 46 drives the circular block 47 to squeeze the spring 48, and at the same time drives the locking flange 49 set on the other side to move out of the through hole opened on the outer wall of the dustproof net 42 set at one end of the mounting tube 40, so that the dustproof net 42 can be disassembled for cleaning to prevent dust from accumulating on the dustproof net 42, so that the ventilation effect is improved, thereby improving the heat dissipation effect.

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