Description

Technical Field

[0001] This invention relates to the field of oil-immersed transformer tank technology, and more specifically, to a bottom assembly of a transformer tank. Background Technology

[0002] A transformer is a device that uses Faraday's law of electromagnetic induction to increase or decrease voltage. Transformers typically contain two or more sets of coils and are mainly used to increase or decrease the voltage of alternating current, change impedance, and separate circuits. They are widely used in power facilities and are an indispensable piece of equipment in production and daily life. Transformers used for testing are called test transformers, which can be classified into gas-filled, oil-immersed, and dry-type test transformers. In an oil-immersed transformer, the transformer core and windings are housed in a tank filled with transformer oil. The tank serves to contain the transformer core, fill it with transformer oil, and provide cooling. The tank has a bottom, and a base is fixed to the lower surface of the bottom, securing the entire tank to the base.

[0003] Existing transformer tank bases typically consist of two channel steels. While this makes installation of the transformer tank convenient, it does not allow for adjustment of the transformer's level. If the transformer tank is tilted after installation, it will affect the smoothness of oil circulation, increase mechanical vibration, and prevent the oil from being evenly distributed within the tank, resulting in different temperatures in different areas and hindering heat dissipation. Therefore, a new type of transformer tank base assembly is needed. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this invention is to provide a transformer tank bottom assembly that can improve installation efficiency and reduce mechanical vibration.

[0005] To address the problems in the background technology, the present invention adopts the following technical solution.

[0006] A transformer tank bottom assembly includes a tank bottom body. A fixing block is fixedly connected to the bottom of the tank bottom body. A support rod rotatably connected to the fixing block is inserted through the fixing block. A gear fixedly connected to the support rod is sleeved on the support rod. The outer side of the gear is rotatably connected to the fixing block. The bottom of the gear passes through and extends to the bottom of the fixing block. A base plate is provided below the fixing block. The top of the base plate is fixedly connected to both ends of the support rod. An adjustment structure is provided at the bottom of the fixing block. Two support plates are fixedly connected to the bottom of the base plate. Locking rods threadedly connected to the front and back of the two support plates are inserted through them. An mounting plate is provided below the base plate. The outer side of the mounting plate contacts the two support plates. A lifting structure is provided on both support plates.

[0007] As a further description of the above technical solution:

[0008] The adjustment structure includes two grooves, both of which are located at the bottom of the fixed block. A lead screw is rotatably connected to the inner wall of the front groove, with one end of the lead screw penetrating and extending to the front of the fixed block.

The front slider is fitted onto the lead screw and threadedly connected to it, while the back slider is fitted onto the limit rod and slidably connected to it. A toothed plate that meshes with a gear is fixedly connected between the two sliders.

[0009] As a further description of the above technical solution:

[0010] The lifting structure includes a screw, one end of which is inserted into and rotatably connected to a support plate. Two adjusting blocks are inserted into and slidably connected to the support plate. The bottom of each adjusting block is in contact with a mounting plate. Each adjusting block has a sliding groove. The inner walls of each sliding groove are slidably connected to a driving block. Each driving block is sleeved on the screw and threadedly connected to it. Sliding rods are fixedly connected to the left and right sides of each driving block. Inclined grooves that match the sliding rods are formed on the left and right sides of each adjusting block.

[0011] As a further description of the above technical solution:

[0012] The slide rod is fitted with a sliding sleeve that is rotatably connected to it, and the outer side of the sliding sleeve is in contact with the inclined groove.

[0013] As a further description of the above technical solution:

[0014] Two blocks are fixedly connected to both the front and back of the fixed block, and each of the four blocks has an auxiliary rod threaded through it.

[0016] The mounting plate has locking grooves fixedly connected to both its front and back sides, and the inner wall of the locking groove is in contact with the locking rod.

[0017] As a further description of the above technical solution:

[0018] Two levels are fixedly connected to the bottom of the box body, and the two levels are respectively located on the front and left side of the bottom of the box body.

[0019] As a further description of the above technical solution:

[0020] The back of the locking groove is provided with equally spaced screw holes, and bolts are threaded onto the screw holes on both the left and right sides.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0031] Please see Figures 1-5In this invention: a transformer tank bottom assembly includes a tank bottom body 1. A fixing block 2 is fixedly connected to the bottom of the tank bottom body 1. A support rod 3 is inserted through the fixing block 2 and rotatably connected thereto. A gear 4 is sleeved on the support rod 3 and fixedly connected thereto. The outer side of the gear 4 is rotatably connected to the fixing block 2. The bottom of the gear 4 extends through and to the bottom of the fixing block 2. A base plate 5 is provided below the fixing block 2. The top of the base plate 5 is fixedly connected to both ends of the support rod 3. An adjustment structure 6 is provided at the bottom of the fixing block 2. Two support plates 7 are fixedly connected to the bottom of the base plate 5. Locking rods 8 are threadedly connected to the front and back of the two support plates 7. An mounting plate 9 is provided below the base plate 5. The outer side of the mounting plate 9 contacts the two support plates 7. A lifting structure 10 is provided on each of the two support plates 7. The adjustment structure 6 includes two grooves 601. Both grooves 601 are opened at the bottom of the fixing block 2. A lead screw 602 is rotatably connected to the inner wall of the front groove 601. One end of the lead screw 602 extends through and to the bottom of the fixing block 2. A limiting rod 603 is fixedly connected to the inner wall of the groove 601 on the front and back sides of the fixing block 2. Sliding blocks 604 are slidably connected to the inner walls of both grooves 601. The front sliding block 604 is sleeved on the lead screw 602 and threadedly connected to it, while the back sliding block 604 is sleeved on the limiting rod 603 and slidably connected to it. A toothed plate 605 that meshes with the gear 4 is fixedly connected between the two sliding blocks 604. The lifting structure 10 includes a screw 101, one end of which is inserted into and rotatably connected to the support plate 7. Two adjusting blocks 102 are inserted through the support plate 7 and slidably connected to it. The bottom of the two adjusting blocks 102 is in contact with the mounting plate 9. Each of the two adjusting blocks 102 has a sliding groove 103. The inner walls of the two sliding grooves 103 are slidably connected to the driving blocks 104. The two driving blocks 104 are sleeved on the screw 101 and threadedly connected to it. The left and right sides of the two driving blocks 104 are fixedly connected to the sliding rods 105. The left and right sides of the two adjusting blocks 102 are provided with inclined grooves 106 that are adapted to the sliding rods 105.

[0032] In this invention, when installing the bottom body 1, the mounting plate 9 is first fixed in a suitable position, and then two support plates 7 are fastened onto the mounting plate 9 to support the bottom body 1 and the transformer. At this time, the user can adjust the angle between the bottom body 1 and the base plate 5 by rotating the lead screw 602. The lead screw 602 is threadedly connected to the slider 604, so after the lead screw 602 rotates, it will drive the slider 604 to slide along the inner wall of the groove 601, thereby driving the toothed plate 605 to move. Since the toothed plate 605 meshes with the gear 4, after the toothed plate 605 moves, it will drive the gear 4 to rotate. After the gear 4 rotates, it will drive the support rod 3 to rotate. After the support rod 3 rotates, it will drive the base plate 5 to rotate. After the base plate 5 rotates, it will change the angle between the bottom body 1 and the base plate 5, thereby realizing the adjustment of the angle of the bottom body 1, and thus realizing the adjustment of the level of the bottom body 1.

[0033] After the user makes an initial adjustment to the bottom body 1, the user can rotate one of the screws 101 to move the bottom body 1 upward on the same side. After the screw 101 rotates, it will drive the two drive blocks 104 to move along the inner wall of the slide 103. As the drive blocks 104 move, they will drive the slide rod 105 to move. After the slide rod 105 moves, it will then press the inclined groove 106. Since the inclined groove 106 is inclined, it will drive the adjusting block 102 to move. After the adjusting block 102 moves, it will then change the distance between the support plate 7 and the mounting plate 9 on the same side as the adjusting block 102, thereby realizing the readjustment of the level of the bottom body 1.

[0034] After adjusting the level of the bottom body 1 of the box twice, the user rotates the locking rod 8 until the locking rod 8 is in close contact with the mounting plate 9, thereby fixing the position of the leveled bottom body 1 of the box and completing the fixed installation of the bottom body 1 of the box.

[0035] Please see Figure 5 The slide rod 105 is fitted with a slide sleeve 11 that is rotatably connected to it, and the outer side of the slide sleeve 11 is in contact with the inclined groove 106.

[0036] In this invention, the sliding sleeve 11 can reduce friction, save the user's physical effort in adjusting the support plate 7 and the mounting plate 9, and reduce wear and increase the service life of the device.

[0037] Please see Figures 1-3 Among them, the front and back of the fixed block 2 are fixedly connected to two square blocks 12, and each of the four square blocks 12 is threaded with an auxiliary rod 13.

[0038] In this invention, after the level of the bottom body 1 of the box is adjusted, the user rotates all the auxiliary rods 13 until the bottom of the auxiliary rods 13 contacts the mounting plate 9. At this time, the auxiliary rods 13 can play the role of auxiliary support for the bottom body 1 of the box, thereby improving the stability of fixing the bottom body 1 of the box.

[0039] Please see Figures 1-3 The mounting plate 9 has a locking groove 14 fixedly connected to both the front and back sides, and the inner wall of the locking groove 14 is in contact with the locking rod 8.

[0040] In this invention, the locking groove 14 can limit the locking rod 8, improve the stability of fixing the bottom body 1 of the box, and improve the safety of the device.

[0041] Please see Figure 2 The bottom of the box body 1 is fixedly connected to two levels 15, which are respectively located on the front and left side of the bottom of the box body 1.

[0042] In this invention, the level 15 can assist workers in leveling the bottom body 1 of the box, thereby improving the practicality of the device.

[0043] Please see Figures 1-3 The locking groove 14 has screw holes 16 arranged at equal intervals on its back side, and bolts 17 are threadedly connected to the screw holes 16 on both the left and right sides.

[0044] In this invention, the screw holes 16 and bolts 17 can limit the left and right positions of the support plate 7, thereby improving the stability of the installation of the box bottom body 1 and enhancing the practicality of the device.

[0045] The above are merely preferred embodiments of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
