DETAILED DESCRIPTION

[0034] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0035] Embodiment 1:

[0036] like Figure 1-Figure 4 As shown, a quick-disassembly and quick-installation dry-type transformer comprises a transformer body 1 and a fixing seat 2, a positioning track 11 is installed at the bottom of the transformer body 1, the positioning track 11 comprises a positioning groove 12, a first positioning plate 13 and a second positioning plate 14 are installed at one end of the positioning track 11 away from the transformer body 1, and the positioning groove 12 is located between the first positioning plate 13 and the second positioning plate 14;

[0037] The fixing seat 2 includes a fixing groove 21, a supporting shell 22 is installed in the fixing groove 21, a power fixing mechanism 3 is installed in the supporting shell 22, the power fixing mechanism 3 includes a first screw rod 31, a second screw rod 32 and a power motor 33, the power motor 33 drives the first screw rod 31 and the second screw rod 32 to rotate, one end of the first screw rod 31 is rotatably connected to the bottom of the supporting shell 22, and the other end of the first screw rod 31 extends toward the first positioning plate 13, the first positioning plate 13 is provided with a first positioning hole 15 that cooperates with the first screw rod 31, the second screw rod 32 is arranged opposite to the first screw rod 31, and the second positioning plate 14 is provided with a second positioning hole 16 that cooperates with the second screw rod 32.

[0038] When in use, first, the fixing seat 2 needs to be placed in a predetermined position; then, the transformer body 1 and the positioning rail 11 are sent to the top of the fixing seat 2; then, the first positioning hole 15 is aligned with the first screw rod 31, and the second positioning hole 16 is aligned with the second screw rod 32; finally, the transformer body 1 is slowly lowered, and the power motor 33 is started at the same time to drive the first screw rod 31 and the second screw rod 32 to rotate. Since the transformer body 1 is extremely heavy, the first screw rod 31 will be threadedly connected with the first positioning hole 15, and the second screw rod 32 will be threadedly connected with the second positioning hole 16 during the slow descent process, until the first positioning plate 13, the second positioning plate 14 abut against the top of the support shell 22, and the power motor 33 stops working. At this point, the installation of the transformer is completed. The entire process only requires attention to the coordination of the screw rod and the positioning hole, and workers no longer need to tighten the bolts. Therefore, even in a relatively narrow space, the transformer can still be quickly assembled.

[0039] If you want to disassemble it quickly, just reverse the above steps.

[0040] Since the transformer will have extremely small and frequent vibrations during operation, if the transformer is fixed with bolts, the bolts are very likely to loosen under extremely frequent vibrations. In this solution, the power motor 33 can drive the first screw rod 31 and the second screw rod 32 to rotate at any time to complete the tightening work of the transformer body 1.

[0041] The transformer in the above scheme needs equipment such as a crane or an electric hoist to complete the lifting and installation work. The reason is that the tops of the first screw rod 31 and the second screw rod 32 in this scheme are protrudingly arranged on the support shell 22. However, in an indoor environment, equipment such as a crane and an electric hoist are difficult to use. In this regard, in order to further facilitate installation, a support roller 17 is installed in the positioning groove 12, and the outer wall of the support roller 17 is recessed toward the axis of the support roller 17 to form a positioning ring groove 18. A support rail 221 is arranged on the top of the support shell 22, and a support plate 34 is arranged at the bottom of the support rail 221. One end of the support plate 34 is threadedly connected to the first screw rod 31, and the other end of the support plate 34 is threadedly connected to the second screw rod 32. A support protrusion 35 is arranged on the top of the support plate 34, and the support roller 17 abuts against the top of the support plate 34. The support protrusion 35 is arranged in cooperation with the positioning ring groove 18.

[0042] Since the support plate 34 and the support roller 17 jointly support the transformer body 1, there is a gap between the first positioning plate 13 of the positioning track 11 and the top of the first screw rod 31. Similarly, there is also a gap between the second positioning plate 14 and the top of the second screw rod 32. Therefore, when in use, it is only necessary to align the support roller 17 with the support plate 34, align the positioning ring groove 18 with the support protrusion 35, and then push the transformer body 1 to press the support plate 34 to move until the other end of the positioning track 11 abuts against the inner wall of the fixing groove 21. At this time, the first screw rod 31 and the second screw rod 32 are respectively aligned with the first positioning hole 15 and the second positioning hole 16. Then start the power motor 33, the power motor 33 will drive the first screw rod 31 and the second screw rod 32 to rotate. During this process, the support plate 34 will gradually descend along the first screw rod 31 and the second screw rod 32, and then the first screw rod 31 and the second screw rod 32 will be threadedly connected with the first positioning hole 15 and the second positioning hole 16 respectively to complete the fixing of the transformer body 1.

[0043] When the support plate 34 drops to a certain height, the first positioning plate 13 and the second positioning plate 14 will abut against the top of the support shell 22. At this time, the weight of the transformer body 1 will be shared by the support shell 22, which avoids the probability of damage to the first screw rod 31 and the second screw rod 32.

[0044] Since the support roller 17 is installed in the positioning groove 12, the worker can push the transformer body 1 into the room.

[0045] In order to facilitate the power motor 33 to drive the first screw rod 31 and the second screw rod 32 to rotate, a driving gear 36 is provided on the outer wall of the first screw rod 31 and the second screw rod 32. A power gear 37 is installed at the power end of the power motor 33, and the power gear 37 is meshed and connected with the driving gear 36.

[0046] Preferably, the first screw rod 31 includes a threaded section 38 and a power section 39, the threaded section 38 is provided with an external thread on its outer wall, the power section 39 is provided with a driving gear 36 on its outer wall, one end of the power section 39 is rotatably connected to the bottom of the support shell 22, one end of the threaded section 38 is connected to the power section 39, the other end of the threaded section 38 is threadedly connected to the first positioning hole 15, the support plate 34 is threadedly connected to the threaded section 38, and the structure of the second screw rod 32 is the same as that of the first screw rod 31.

[0047] In order to prevent the components in the transformer from being damaged due to up and down vibrations, a buffer shell 23 is further provided in the fixing groove 21 , the support shell 22 is slidably provided in the buffer shell 23 , and a first buffer 24 is provided between the bottom of the support shell 22 and the bottom of the buffer shell 23 .

[0048] Although the first buffer 24 mitigates the impact of vibration on the transformer body 1, since the support shell 22 is slidably arranged in the buffer shell 23, if the support shell 22 is not restricted, it will cause the support shell 22 to vibrate with a large amplitude. To this end, a first pressing plate 26 and a second pressing plate 27 are horizontally arranged in the fixing groove 21. The first pressing plate 26 and the second pressing plate 27 are respectively located on both sides of the buffer shell 23, and the bottom of the first pressing plate 26 and the bottom of the second pressing plate 27 are both in contact with the top of the support shell 22. The first pressing plate 26 and the second pressing plate 27 are respectively arranged on both sides of the support shell 22. At this time, the first pressing plate 26 and the second pressing plate 27 will limit the support shell 22 to prevent it from vibrating with a large amplitude.

[0049] Preferably, a rubber cushion is provided at one end of the first pressing plate 26 and the second pressing plate 27 facing the supporting shell 22. The purpose of this design is to reduce the noise generated when the supporting shell 22 and the two pressing plates collide.

[0050] In order to prevent the transformer body 1 from being affected by lateral vibration, a plurality of second buffers 25 are arranged between the fixing groove 21 and the buffer shell 23 , and the plurality of second buffers 25 are arranged around the buffer shell 23 .

[0051] There are many options for the first buffer 24 and the second buffer 25, such as a hydraulic rod, an air spring, and a compression spring.

[0052] Embodiment 2:

[0053] Transformers often have a very long service life, which means that it takes a long time for the transformer to be repaired or replaced. If the transformer is in a humid environment for a long time, the connection between the fixing base 2 and the transformer is very likely to rust, which will make the transformer body 1 difficult to dismantle and repair. To this end, we need to slow down the corrosion rate of the first screw rod 31, the second screw rod 32 and other structures. Figure 5-8 As shown, a limiting cap 4 is installed on the top of the first screw rod 31, and the limiting cap 4 includes an oil storage chamber 41 and a limiting chamber 42. The top of the first screw rod 31 is slidably arranged in the limiting chamber 42. A sealing cover 43 is arranged at one end of the oil storage chamber 41 away from the limiting chamber 42, and an oil outlet 44 is arranged at one end of the oil storage chamber 41 facing the limiting chamber 42. Lubricating oil is arranged in the oil storage chamber 41. When in use, lubricating oil is first injected into the oil storage chamber 41, and then the sealing cover 43 is covered on the top of the oil storage chamber 41 to complete the sealing of the oil storage chamber 41. Then the limiting cap 4 is buckled on the top of the first screw rod 31 and the second screw rod 32. At this time, the lubricating oil will gradually reach the top of the first screw rod 31 through the oil outlet hole, and slowly descend along the outer wall of the first screw rod 31 under the influence of gravity. Since an external thread is provided on the outer wall of the first screw rod 31 , the lubricating oil will gradually cover the outer wall of the threaded section 38 of the first screw rod 31 under the guidance of the external thread, thereby completing the sealing and lubrication of the first screw rod 31 and reducing the probability of rust.

[0054] In order to slow down the speed of the lubricating oil being discharged from the oil storage chamber 41, a limiting mechanism 45 is installed in the oil storage chamber 41, and the limiting mechanism 45 includes a sealing ball 451, and the oil outlet 44 is arranged around the sealing ball 451, and a part of the sealing ball 451 is in contact with the top of the first screw rod 31; the limiting mechanism 45 also includes a limiting platform 452, and a limiting arm 453 is arranged on the side wall of the limiting platform 452, and a limiting groove 454 is arranged on the inner wall of the oil storage chamber 41, and a limiting compression spring 455 is installed in the limiting groove 454, and the end of the limiting arm 453 away from the limiting platform 452 is connected to the limiting compression spring 455, and the side of the limiting platform 452 facing the sealing ball 451 is a spherical surface, and the sealing ball 451 is in contact with the limiting platform 452. The characteristic that the transformer will vibrate slightly when working is used to assist the sealing ball 451 to deliver the lubricating oil to the outer wall of the first screw rod 31. When the transformer vibrates laterally, the limit cap 4 will also vibrate laterally with the transformer. At this time, the sealing ball 451 and the top of the first screw rod 31 will be relatively displaced, so that the lubricating oil inside the oil storage chamber 41 will be smeared to the top of the first screw rod 31 by the sealing ball 451 as the sealing ball 451 rotates.

[0055] When the transformer vibrates longitudinally, the sealing ball 451 will squeeze the limiting platform 452, and the limiting platform 452 will squeeze the limiting compression spring 455 through the limiting arm 453. At this time, a gap will appear between the sealing ball 451 and the oil outlet 44, and the lubricating oil will flow out quickly. As the limiting compression spring 455 drives the limiting platform 452 to reset, the sealing ball 451 will seal the oil outlet 44 again. Therefore, when the transformer vibrates longitudinally, the limiting cap 4 will intermittently deliver the lubricating oil to the top of the first screw rod 31.

[0056] In summary, this design ensures that no matter the transformer vibrates horizontally or longitudinally, the lubricating oil in the limiting cap 4 can be delivered to the top of the first screw rod 31 to complete the lubrication and sealing of the first screw rod 31 .

[0057] In order to speed up the downward flow of lubricating oil, a support section 46 is provided at the top of the first screw rod 31, the limiting cavity 42 is slidably connected with the support section 46, an oil guide cavity 47 is provided inside the support section 46, the top of the support section 46 is a spherical surface, the top of the support section 46 is in contact with the sealing ball 451, an oil guide through hole 48 is provided between the top of the support section 46 and the oil guide cavity 47, an oil distribution platform 49 and a plurality of liquid outlet holes 50 are provided at the bottom of the support section 46, and the plurality of liquid outlet holes 50 are arranged around the oil distribution platform 49, and the oil distribution platform 49 is conical. When in use, the lubricating oil will pass through the oil outlet 44, the oil guide through hole 48, the oil guide cavity 47 in sequence, and then reach the oil distribution platform 49, and then be evenly guided to the liquid outlet hole 50 by the oil distribution platform 49, and then the lubricating oil reaches the threaded section 38 of the first screw rod 31 through the liquid outlet hole 50. This design shortens the length of the threaded section 38, thereby shortening the time that the lubricating oil stays on the outer wall of the first screw rod 31 and accelerating the downstream speed of the lubricating oil.

[0058] In order to prevent the driving gear 36 from hindering the lubricating oil from descending, the driving gear 36 includes a connecting cavity 361, the length direction of the connecting cavity 361 is the same as the length direction of the first screw rod 31, and a plurality of connecting arms 362 are provided between the connecting cavity 361 and the first screw rod 31. This design enables the lubricating oil to continue to flow downward through the connecting cavity 361.

[0059] Since the first screw rod 31 is rotatably connected to the bottom of the support shell 22, in order to prevent the connection between the first screw rod 31 and the support shell 22 from being unable to rotate due to rust, a support platform 51 is provided at the bottom of the support shell 22, and an oil collecting chamber 52 and a power platform 53 are provided in the support platform 51. The bottom of the first screw rod 31 is rotatably connected to the power platform 53, and a discharge hole is provided on the inner wall of the oil collecting chamber 52. The lubricating oil descending along the first screw rod 31 will reach the support platform 51, and then pass through the gap between the first screw rod 31 and the support platform 51 and the power platform 53 to enter the oil collecting chamber 52 for temporary storage. When the lubricating oil in the oil collecting chamber 52 reaches a certain amount, the lubricating oil will be discharged through the discharge hole.

[0060] In order to seal the support platform 51, the support platform 51 includes a support cover 54, and the support cover 54 includes a support hole 55. The support cover 54 is located at one end of the power platform 53 away from the oil collecting chamber 52. The support hole 55 is arranged around the first screw rod 31. A plurality of lubricating balls 56 are arranged between the support hole 55 and the first screw rod 31. The lubricating oil can assist the rotation of the first screw rod 31 to prevent it from deviating from its rotation axis during rotation. The downstream lubricating oil will lubricate the lubricating balls 56 to reduce the probability of rust.

[0061] In order to facilitate the lubricating oil to reach the oil collecting chamber 52, one end of the power platform 53 facing the first screw rod 31 is recessed to form a power groove 57, and a drainage hole 58 is arranged between the power platform 53 and the oil collecting chamber 52, one end of the drainage hole 58 is connected to the power groove 57, and the other end of the drainage hole 58 is connected to the oil collecting chamber 52. A support block 60 is installed at the bottom of the first screw rod 31, and a plurality of support balls 59 are arranged at the bottom of the support block 60 and the power groove 57, and the support balls 59 are arranged around the drainage hole 58. The support balls 59 have the same function as the lubricating balls 56, wherein the lubricating oil will first pass through the support balls 59 and lubricate the support balls 59 during the process of flowing to the oil collecting chamber 52.

[0062] Embodiment 3:

[0063] Since the support plate 34 is threadedly connected to the threaded section 38, the gap between the support plate 34 and the threaded section 38 is extremely small, which causes the speed at which the lubricating oil flows downward to be extremely slow. Figure 9-10 As shown, in order to prevent the lubricating oil from accumulating on the top of the support plate 34, a trumpet-shaped collecting groove 61 is provided on the top of the support plate 34, and the collecting groove 61 is arranged around the threaded section 38. A guide cavity 62 is provided at the bottom of the support plate 34, and the guide cavity 62 is arranged opposite to the collecting groove 61, and the guide cavity 62 is arranged around the threaded section 38. A guide pipe 63 is provided between the collecting groove 61 and the guide cavity 62, and a guide hole 64 is opened at the bottom of the guide cavity 62, and the guide hole 64 is arranged around the threaded section 38. When the lubricating oil fills the collecting groove 61, the lubricating oil will reach the guide cavity 62 through the guide pipe 63, and then reach the threaded section 38 below the support plate 34 under the guidance of the guide hole 64.

[0064] A limiting cap 4 is also provided at the top end of the second screw rod 32 in this solution.

[0065] In order to facilitate guiding the transformer body 1 to the fixing seat 2 , an auxiliary plate is provided at one end of the support rail 221 , and one end of the auxiliary plate is hinged to the side wall of the fixing seat 2 .

[0066] In summary, the advantages of this solution are: First, the transformer body 1 can be quickly installed on the fixed seat 2 by cooperating with the first screw rod 31, the second screw rod 32 and the first positioning plate 13, the second positioning plate 14. Second, the support roller 17 cooperates with the support plate 34, so that the extremely heavy transformer body 1 can be quickly assembled and disassembled without using equipment such as a crane. Third, the first buffer 24 and the second buffer 25 are used to slow down the vibration amplitude of the transformer body 1, thereby extending the service life of the transformer. Fourth, the limit cap 4 is used to slowly transport lubricating oil to the first screw rod 31 and the second screw rod 32, and the lubricating oil will gradually cover the outer walls of the first screw rod 31 and the second screw rod 32, which slows down the corrosion rate of the first screw rod 31 and the second screw rod 32.

[0067] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by ordinary technicians in this field based on the above-mentioned concepts without creative work are all within the protection scope of the present invention.
