Description

Technical Field

[0001] This utility model relates to the field of transformer technology, specifically to a device for increasing the strength of high-corrugated sheets in transformers. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are the primary coil, secondary coil, and iron core (magnetic core). Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization (magnetic saturation transformer). The transformer tank typically has corrugated sheets on its perimeter for heat dissipation. During transportation, installation, and use, these corrugated sheets are easily deformed or even damaged by impacts, affecting their normal operation. Therefore, it is proposed to add high-strength devices to the transformer corrugated sheets to increase their strength. Utility Model Content

[0003] To address the problems in the prior art, this utility model provides a device for increasing the strength of high-corrugated sheets in transformers.

[0004] The technical solution adopted by this utility model to solve its technical problem is a device for increasing the strength of high-corrugated sheets in transformers, including a support member and an adjusting member. Two support members and two adjusting members are provided. Between the two adjusting members are a first reinforcing block, a limiting bolt, a second reinforcing block, and a third reinforcing block. Multiple slots are provided on one side of each of the first, second, and third reinforcing blocks. Insert blocks are integrally formed at the ends of the second and third reinforcing blocks near the first reinforcing block. The ends of the first and second reinforcing blocks near the third reinforcing block... Each part is provided with a slot adapted to the insert block. The top of the first reinforcing block and the second reinforcing block are provided with screw holes adapted to the limiting bolts. Each insert block is provided with a slot adapted to the limiting bolts. The adjusting component includes a sleeve, a lead screw and a base. The base near the first reinforcing block is connected to the first reinforcing block, and the base near the third reinforcing block is connected to the third reinforcing block. The sleeve is fitted onto one end of the base. The sleeve is provided with a screw hole adapted to the lead screw. One end of the lead screw is rotatably connected to the base, and the other end of the lead screw is fixed with a knob.

[0005] By adopting the above technical solution, the support and adjustment components can support the first, second, and third reinforcing blocks. The insertion blocks at the ends of the second and third reinforcing blocks, the slots at the ends of the first and second reinforcing blocks, and the limiting bolts can increase the number of second reinforcing blocks as needed. Rotating the two knobs can adjust the distance between the first, second, and third reinforcing blocks and the transformer tank as needed. Rotating the two knobs in the opposite direction allows the ends of the corrugated sheets away from the tank to be inserted into the slots on the side walls of the first, second, and third reinforcing blocks, thereby improving the strength of the corrugated sheets.

[0006] Specifically, the knob has multiple anti-slip grooves.

[0007] By adopting the above technical solution, the anti-slip texture makes it easier to grip and rotate the knob.

[0008] Specifically, the support includes a bracket and a connecting bolt. One end of the bracket is integrally formed with a protrusion. The end of the sleeve near the bracket is provided with a slot that matches the protrusion. The sleeve is provided with a screw hole that matches the connecting bolt. The protrusion is provided with a slot that matches the connecting bolt.

[0009] By adopting the above technical solution, the adjusting component, along with the first, second, and third reinforcing blocks, can be removed for maintenance by loosening the two connecting bolts and pulling the two sleeves away from the oil tank. This avoids the adjusting component, the first, second, and third reinforcing blocks obstructing the corrugated sheet and affecting its maintenance.

[0010] Specifically, two reinforcing blocks are fixed on the support.

[0011] By adopting the above technical solution and strengthening the block, the strength of the support can be improved.

[0012] Specifically, the first, second, and third reinforcing blocks are all made of metal.

[0013] The beneficial effects of this utility model are:

[0014] (1) The device for increasing the strength of high corrugated sheet of transformer described in this utility model has a support and adjustment component that can support the first reinforcement block, the second reinforcement block and the third reinforcement block. The insertion blocks at the ends of the second reinforcement block and the third reinforcement block, the slots at the ends of the first reinforcement block and the second reinforcement block and the limiting bolts can increase the number of second reinforcement blocks as needed. Rotating the two knobs can adjust the distance between the first reinforcement block, the second reinforcement block and the third reinforcement block and the transformer tank as needed. Rotating the two knobs in the opposite direction allows the end of the corrugated sheet away from the tank to be inserted into the slot on the side wall of the first reinforcement block, the second reinforcement block and the third reinforcement block, which can improve the strength of the corrugated sheet.

[0015] (2) The device for increasing the strength of high corrugated sheet of transformer described in this utility model can be removed for maintenance by loosening the two connecting bolts and pulling the two sleeves away from the oil tank. This also avoids the adjustment component, the first reinforcement block, the second reinforcement block and the third reinforcement block blocking the corrugated sheet and affecting the maintenance of the corrugated sheet.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] To improve the strength of the corrugated sheet, as one embodiment of this utility model, such as Figure 1 , Figure 2 As shown, the device for increasing the strength of high-corrugated sheet transformers according to this utility model includes a support member 1 and an adjusting member 7. Two support members 1 and two adjusting members 7 are provided. Between the two adjusting members 7 are a first reinforcing block 10, a limiting bolt 11, a second reinforcing block 12, and a third reinforcing block 13. Multiple slots are provided on one side of each of the first reinforcing block 10, the second reinforcing block 12, and the third reinforcing block 13. Inserts 14 are integrally formed at the ends of the second reinforcing block 12 and the third reinforcing block 13 near the first reinforcing block 10. The ends of the first reinforcing block 10 and the second reinforcing block 12 near the third reinforcing block 13 are provided with insertion blocks 14. 4. Adaptive slots: The top of the first reinforcing block 10 and the second reinforcing block 12 are provided with screw holes adapted to the limiting bolts 11. Each of the insert blocks 14 is provided with a slot adapted to the limiting bolts 11. The adjusting component 7 includes a sleeve 5, a lead screw 8 and a base 9. The base 9 near the first reinforcing block 10 is welded to the first reinforcing block 10. The base 9 near the third reinforcing block 13 is welded to the third reinforcing block 13. The sleeve 5 is fitted onto one end of the base 9. The sleeve 5 is provided with screw holes adapted to the lead screw 8. One end of the lead screw 8 is rotatably connected to the base 9. The other end of the lead screw 8 is welded and fixed with a knob 6.

[0023] In use, the support member 1 and the adjusting member 7 can support the first reinforcing block 10, the second reinforcing block 12 and the third reinforcing block 13. The insertion blocks 14 at the ends of the second reinforcing block 12 and the third reinforcing block 13, the slots at the ends of the first reinforcing block 10 and the second reinforcing block 12 and the limiting bolts 11 can increase the number of second reinforcing blocks 12 as needed. Rotating the two knobs 6 can adjust the distance between the first reinforcing block 10, the second reinforcing block 12 and the third reinforcing block 13 and the transformer tank as needed. Rotating the two knobs 6 in the opposite direction moves the first reinforcing block 10, the second reinforcing block 12 and the third reinforcing block 13 toward the tank. The ends of the corrugated sheets away from the tank are inserted into the slots on the side walls of the first reinforcing blocks 10, the second reinforcing blocks 12 and the third reinforcing blocks 13, which can improve the strength of the corrugated sheets.

[0024] For ease of rotating knob 6, exemplarily, such as Figure 1 As shown, the knob 6 has multiple anti-slip grooves.

[0025] For ease of disassembly, for example, such as Figure 1 , Figure 3 As shown, the support member 1 includes a support 2 and a connecting bolt 4. One end of the support 2 is integrally formed with a protrusion 20. The end of the sleeve 5 near the support 2 is provided with a slot that matches the protrusion 20. The sleeve 5 is provided with a screw hole that matches the connecting bolt 4. The protrusion 20 is provided with a slot that matches the connecting bolt 4.

[0026] When in use, loosen the two connecting bolts 4 and pull the two retaining sleeves 5 away from the oil tank to remove the adjusting part 7 together with the first reinforcing block 10, the second reinforcing block 12 and the third reinforcing block 13 for maintenance. This avoids the adjusting part 7, the first reinforcing block 10, the second reinforcing block 12 and the third reinforcing block 13 from obstructing the corrugated sheet and affecting its maintenance.

[0027] To improve the strength of support 2, for example, such as Figure 1 As shown, two reinforcing blocks 3 are welded and fixed on the support 2.

[0028] The first reinforcing block 10, the second reinforcing block 12 and the third reinforcing block 13 are all made of metal.

[0029] In use, the support member 1 and the adjusting member 7 can support the first reinforcing block 10, the second reinforcing block 12 and the third reinforcing block 13. The insertion blocks 14 at the ends of the second reinforcing block 12 and the third reinforcing block 13, the slots at the ends of the first reinforcing block 10 and the second reinforcing block 12 and the limiting bolts 11 can increase the number of second reinforcing blocks 12 as needed.

[0030] Rotating the two knobs 6 allows adjustment of the distance between the first reinforcing block 10, the second reinforcing block 12, the third reinforcing block 13 and the transformer tank as needed. Moving the two supports so that multiple corrugated sheets are positioned between the two supports, the two supports 2 are welded to the tank. Rotating the two knobs 6 in the opposite direction moves the first reinforcing block 10, the second reinforcing block 12, and the third reinforcing block 13 toward the tank. The ends of the corrugated sheets away from the tank are inserted into the slots on the side walls of the first reinforcing block 10, the second reinforcing block 12, and the third reinforcing block 13. Multiple of these devices can be installed on the tank as needed to improve the strength of the corrugated sheets.

[0031] Loosen the two connecting bolts 4 and pull the two retaining sleeves 5 away from the oil tank to remove the adjusting component 7 along with the first reinforcing block 10, the second reinforcing block 12 and the third reinforcing block 13 for maintenance. This will prevent the adjusting component 7, the first reinforcing block 10, the second reinforcing block 12 and the third reinforcing block 13 from obstructing the corrugated sheet and affecting its maintenance.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
