Description

Technical Field

[0002] A transformer is a device that adjusts the AC voltage through electromagnetic induction. By using a transformer, when performing long-distance AC power transmission, the stability of the transmission voltage is maintained, effectively avoiding voltage instability caused by power consumption due to resistance problems during the transmission of AC power, which affects the normal supply and use of electric energy.

[0029] The following further elaborates on the present invention in conjunction with the attached Figure 1 —9.

[0030] An embodiment of the present invention discloses a transformer with a lightning protection structure, including a base 1. A transformer main body 2 is arranged on the top of the base 1. A rain sensor is arranged on the top of the transformer main body 2. Heat dissipation fins 3 are installed on both side walls of the transformer main body 2.

Heat dissipation mechanisms are also arranged on both end walls of the transformer main body 2. A protection component for protecting a lightning rod 9 is further arranged on the top of the transformer main body 2. The driving mechanism includes a first motor 4 installed on the top of the transformer main body 2. The output end of the first motor 4 is connected to one end of a transmission shaft, and the other end of the transmission shaft is fixedly installed with a small gear 5. The small gear 5 meshes with a large gear 6. A mounting seat 8 is fixedly installed on the top of the transformer main body 2.

The protection component includes two protective covers 26 and a fixing plate 28. Two symmetric support blocks 23 are fixedly installed on the top of the transformer main body 2. A bidirectional lead screw 24 for rotation is installed on the two support blocks 23. One end of the bidirectional lead screw 24 is installed with a small transmission wheel 20. The other end of the bidirectional lead screw 24 is installed with a bearing seat on one of the support blocks 23 through a bearing. A transmission belt 21 is arranged between the small transmission wheel 20 and a large transmission wheel 22 installed on the transmission shaft. One end of each of the two protective covers 26 is provided with a thread sleeve block 25, and the thread sleeve block 25 is adaptively installed with the bidirectional lead screw 24. A slot is opened on the top of the fixing plate 28, and a guide rod 29 is fixedly installed between the inner walls of the slot. Guide blocks 27 are arranged at the bottoms of the two protective covers 26, and the guide blocks 27 move on the guide rod 29. More specifically, by driving the first motor 4, the small gear 5 installed at one end of the transmission shaft rotates counterclockwise to drive the large gear 6 to rotate. While the large gear 6 rotates, it drives the rotating seat 7 to rotate along the mounting seat 8, thereby driving the lightning rod 9 fixedly installed on the top to rotate into the protective cover 26 arranged on the top of the transformer main body 2. At the same time, the large transmission wheel 22 installed at one end of the transmission shaft rotates counterclockwise through the transmission belt 21 to drive the small transmission wheel 20 installed at one end of the bidirectional lead screw 24 to rotate, so that the bidirectional lead screw 24 rotates along the two support blocks 23, and drives the two protective covers 26 to slide towards each other along the guide rod 29 installed in the slot opened on the top of the fixing plate 28 through the guide blocks 27 arranged at the bottoms, thereby covering the lightning rod 9 inside for protection.

[0031] Reference Figure 2 、 Figure 3 and Figure 4, the clamping assembly includes an L-shaped fixing plate 10. An electric push rod 11 is installed on the side wall of the L-shaped fixing plate 10. One end of the electric push rod 11 passes through a through hole opened on the side wall of the L-shaped fixing plate 10 and is connected to a clamping convex tooth 12. The convex tooth provided on one side of the clamping convex tooth 12 is inserted into a corresponding tooth groove on the large gear 6. More specifically, drive the first motor 4 to make the small gear 5 installed at one end of the transmission shaft rotate clockwise to drive the large gear 6 to rotate, so that the lightning rod 9 can be rotated out of the protective cover 26 and be in a vertical state. Then drive the electric push rod 11 installed on one side of the L-shaped fixing plate 10 to make the electric push rod 11 drive the clamping convex tooth 12 connected to one end to move forward and insert into the corresponding tooth groove on the large gear 6, thereby clamping the large gear 6 and making the lightning rod 9 maintain a more stable vertical state. The fixing assembly includes two symmetric L-shaped fixing blocks 13. The screw holes opened on the L-shaped fixing blocks 13 are adaptively installed with the lead screw 14, and one end of the lead screw 14 is installed with a bearing seat installed on the top of the arc-shaped pressing block 15 through a bearing. A convex block 17 is provided on the outer wall of the arc-shaped pressing block 15, and a support rod 18 passes through a through hole opened on the convex block 17. The two ends of the support rod 18 are respectively connected between the L-shaped fixing block 13 and the mounting block. A limiting flange 16 is provided at the bottom of the arc-shaped pressing block 15. The bottom end of the lightning rod 9 is installed on the top of the circular bottom plate 19. Two groups of limiting holes are opened on the circular bottom plate 19. The limiting flange 16 provided at the bottom of the arc-shaped pressing block 15 is inserted into the corresponding limiting holes. More specifically, by rotating the lead screws 14 provided on the tops of the two L-shaped fixing blocks 13 on the top of the rotating base 7, the lead screws 14 drive the arc-shaped pressing block 15 to move up and down along the support rod 18 through the convex block 17 provided on the side wall, so as to drive the limiting flange 16 provided at the bottom to insert into or disengage from the two groups of limiting holes opened on the circular bottom plate 19 at the bottom of the lightning rod 9, making it more convenient for the staff to install and disassemble the lightning rod 9 and improving the convenience.

[0032] Reference Figure 6 , Figure 7, the protection mechanism includes support plates 30 fixedly installed on both side walls of the transformer body 2. A servo motor 31 is fixedly installed on the top of the support plate 30. The output end of the servo motor 31 is connected to one end of the first lead screw 33. The other end of the first lead screw 33 is installed through a bearing on the bearing seat installed on the top of the base 1. A first sprocket 38 is arranged at the bottom position of the first lead screw 33. The first sprocket 38 is installed with a second sprocket installed on the second lead screw through a chain 39. Both ends of the second lead screw are respectively installed through bearings on the bearing seats of the support plate 30 and the base 1. The first lead screw 33 and the second lead screw are adaptively installed with corresponding movable blocks 34. One end of the movable block 34 is installed with a first connecting seat 35. The first connecting seat 35 is rotatably installed with one end of the movable rod 36. The other end of the movable rod 36 is rotatably installed with a second connecting seat 37 installed on the inner wall of the protection plate 32. One end of the protection plate 32 is rotatably installed with the support plate 30. More specifically, by driving the servo motor 31, the first lead screw 33 drives the second sprocket arranged at the bottom of the second lead screw to rotate through the action of the first sprocket 38 and the chain 39 arranged at the bottom, so that the first lead screw 33 and the second lead screw rotate synchronously to drive the movable block 34 arranged at the middle position to move up and down. While the movable block 34 moves up and down, the protection plate 32 rotatably installed on one side of the support plate 30 rotates to adjust the angle through the action among the first connecting seat 35, the movable rod 36 and the second connecting seat 37, so that the protection effect of the protection plate 32 on the heat dissipation fins 3 reaches the best, and the protection performance is improved.

[0033] Reference Figure 8 , Figure 9, the heat dissipation mechanism includes an installation cylinder 40 installed on the transformer body 2. A fixing ring 41 is provided at one port of the installation cylinder 40. A cross fixing frame 43 is fixedly installed inside the installation cylinder 40. A heat dissipation fan 44 is installed on the cross fixing frame 43. A locking component for locking and fixing the dust-proof net 42 is installed on the installation cylinder 40. The locking component includes a sleeve 45 installed on the outer wall of the installation cylinder 40. A pull rod 46 for pulling is arranged inside the sleeve 45. One end of the pull rod 46 is fixedly installed with a circular block 47. A spring 48 is arranged at a section position on the pull 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 arranged at one end of the circular block 47, and the locking flange 49 is inserted into a corresponding fixing hole opened on the outer wall of the dust-proof net 42. More specifically, the installation cylinder 40 is fixedly installed in a through hole opened on the side walls at both ends of the transformer body 2 through the fixing ring 41 and a bolt arranged on one side. When the heat inside the transformer body 2 is too high, the heat dissipation fan 44 installed inside the installation cylinder 40 is driven to cool the inside, so that the heat dissipation effect of the transformer body 2 is improved. At the same time, the pull rod 46 passing through the inside of the sleeve 45 arranged on the outer wall of the installation cylinder 40 is pulled, so that the pull rod 46 drives the circular block 47 to squeeze the spring 48 connected to one side, so that the circular block 47 slides along the inside of the installation cylinder 40 to drive the locking flange 49 arranged on the other side to overflow from the through hole opened on the outer wall of the dust-proof net 42 arranged at one end of the installation cylinder 40, so that the dust-proof net 42 can be disassembled and cleaned, preventing dust from accumulating on the dust-proof net 42, improving the ventilation effect, and thus improving the heat dissipation effect.

[0034] The implementation principle of a transformer with a lightning protection structure in an embodiment of the present invention is as follows: When the rain drop sensor does not detect rain, the first motor 4 operates, causing the small gear 5 to rotate counterclockwise to drive the large gear 6 to rotate. The rotation of the large gear 6 drives the rotation of the rotating seat 7, thereby driving the lightning rod 9 fixedly installed at the top to rotate into the protective cover 26 provided at the top of the transformer body 2. 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, causing the bidirectional lead screw 24 to rotate between the two support blocks 23, and driving the two protective covers 26 to slide towards each other along the guide rod 29 through the guide blocks 27 provided at the bottom, covering the lightning rod 9 inside to protect it and improve the service life of the lightning rod 9. When the rain drop sensor detects rain, the first motor 4 operates, causing the small gear 5 to rotate clockwise to drive the large gear 6 to rotate, causing the rotating seat 7 to drive the lightning rod 9 fixed at the top to rotate out of the protective cover 26. The two protective covers 26 expand outwards synchronously. When the lightning rod 9 rotates to be perpendicular to the transformer body 1, the driving electric push rod 11 drives the clamping convex teeth 12 to move forward and insert into the corresponding tooth grooves on the large gear 6, thereby clamping the large gear 6, making the lightning rod 9 maintain a more stable vertical state. When protecting the heat dissipation fins 3, the driving servo motor 31 is used to cause the first lead screw 33 to drive the second sprocket provided at the bottom of the second lead screw to rotate through the action of the first sprocket 38 and the chain 39, causing the first lead screw 33 and the second lead screw to rotate synchronously to drive the movable block 34 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 and adjusted in 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 reaches the best. When the temperature inside the transformer body 2 is too high, the heat dissipation fan 44 installed inside the installation cylinder 40 is driven to cool the inside, improving the heat dissipation effect of the transformer body 2. At the same time, the pull rod 46 extending out of the sleeve 45 is pulled, causing the pull rod 46 to drive the circular block 47 to squeeze the spring 48, and at the same time driving the locking flange 49 provided on the other side to move out of the through hole opened on the outer wall of the dust-proof net 42 provided at one end of the installation cylinder 40, so that the dust-proof net 42 can be disassembled and cleaned to prevent dust from accumulating on the dust-proof net 42, improving the ventilation effect and thus improving the heat dissipation effect.

[0035] The above are all the 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.
