[0002] Metal-enclosed busbars are assemblies that enclose conductors and insulation in a metal casing, belonging to power system equipment. After large-sized metal busbars are supported and fixed, they undergo thermal expansion and contraction due to outdoor temperature changes. Since the busbars are fixed to the support frame, this can easily cause them to crack during thermal expansion and contraction, severely affecting their service life. Furthermore, different clamps are required for supporting and fixing metal busbars of different sizes, making the process more complex, time-consuming, and labor-intensive, increasing maintenance costs.

[0020] In the following description, specific details such as particular system structures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art will understand that the present invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0021] Please see Figures 1 to 4 The first embodiment of the present invention provides a lateral tension prevention device for a metal busbar 2. This device includes a support frame 1 and limiting components 3 respectively disposed on both sides of the metal busbar 2. Both limiting components 3 are mounted on the support frame 1, and a receiving space 4 is formed between the two limiting components 3 to accommodate and support the metal busbar 2. Each limiting component 3 includes a limiting member 31 and an adjusting member 32. The limiting member 31 is obliquely mounted on the side of the metal busbar 2 via the adjusting member 32. The adjusting member 32 is installed between the limiting member 31 and the support frame 1, changing the height difference between the two ends of the limiting member 31 to allow the limiting member 31 to form different tilt angles.

[0022] This application utilizes a support frame 1 and limiting components 3 respectively disposed on both sides of the metal busbar drum 2. Both limiting components 3 are mounted on the support frame 1, forming an accommodating space 4 between them to support the metal busbar drum 2. The two limiting components 3 are inclined inward to form a V-shape. The accommodating space 4 allows the metal busbar drum 2 to be laterally limited on the support frame 1, thereby achieving the purpose of supporting and fixing the metal busbar drum 2. The limiting member 31 is obliquely mounted on the side of the metal busbar drum 2 via an adjusting member 32, which is installed between the limiting member 31 and the support frame 1. Changing the position of the limiting member 31... The height difference at both ends allows the limiting member 31 to form different tilt angles. The limiting member 31 can be adjusted to match the tilt angle of the metal busbar 2 according to different specifications, so that the limiting members 31 on both sides can stably limit the metal busbar 2 of different specifications laterally in the accommodating space 4, thereby improving the stability of the metal busbar 2. Furthermore, by adjusting the tilt angle of the limiting members 31 on both sides, the support height and support position of the metal busbar 2 can be changed, thus allowing for fine-tuning when arranging the metal busbar 2. This makes it suitable for more installation environments and expands the scope of use.

[0023] When the metal busbar 2 deforms due to thermal expansion and contraction, the limiting member 31 can always maintain close contact with it by utilizing the weight of the metal busbar 2 itself, effectively preventing the lateral stretching of the metal busbar 2. In practical applications, when the metal busbar 2 expands due to heat, its diameter increases. At this time, the limiting members 31 on both sides limit the lateral movement of the metal busbar 2, but not its longitudinal movement. The metal busbar 2 expands longitudinally, thus buffering its own expansion. This prevents the metal busbar 2 from cracking due to the supporting components and stably confines it laterally within the accommodating space 4. Similarly, when the metal busbar 2 cools and contracts, its diameter decreases. The limiting members 31 on both sides remain in close contact with the metal busbar 2, limiting its lateral movement, while the metal busbar 2 contracts longitudinally without being obstructed by the limiting members 31. This avoids stress concentration caused by expansion or contraction, ensuring the structural integrity of the metal busbar 2. This, in turn, extends the service life of the metal busbar 2, reduces maintenance costs, and improves safety and stability.

[0024] Moreover, since the tilt angle of the limiting member 31 is adjustable, when facing metal busbar drums 2 of different specifications, it is only necessary to change the relative height of the two ends of the limiting member 31 by adjusting the adjusting member 32, so that the limiting member 31 can form a tilt angle that matches the two sides of the metal busbar drum 2, thereby achieving stable limiting of metal busbar drums 2 of different specifications. There is no need to replace the clamps of different specifications, which simplifies the installation operation process, improves the installation efficiency, reduces labor intensity, and reduces maintenance costs.

[0025] Please see Figures 1 to 4 In some embodiments, the adjusting member 32 includes: a mounting base 321, a first adjusting bracket 322, a second adjusting bracket 323, and a locking member 324. The mounting base 321 is mounted on the support frame 1 and is provided with a plurality of adjusting holes 325. One end of the first adjusting bracket 322 and the second adjusting bracket 323 are respectively mounted on different adjusting holes 325 through the locking member 324. The other end of the first adjusting bracket 322 is mounted on one end of the limiting member 31, and the other end of the second adjusting bracket 323 is mounted on the other end of the limiting member 31.

[0026] This application uses a mounting base 321 to be installed on a support frame 1. The mounting base 321 is provided with multiple adjustment holes 325. One end of the first adjustment frame 322 and the second adjustment frame 323 are respectively installed on different adjustment holes 325 through locking members 324. The other end of the first adjustment frame 322 is installed on one end of the limiting member 31, and the other end of the second adjustment frame 323 is installed on the other end of the limiting member 31. First, the mounting base 321 is fixed on the support frame 1. Then, by selecting different adjustment holes 325 to install the first adjustment frame 322 and the second adjustment frame 323, the tilt angle and relative position between the first adjustment frame 322 and the second adjustment frame 323 can be changed, thereby changing the relative height of the two ends of the limiting member 31, so that the limiting member 31 forms different tilt angles to adapt to metal busbar drums 2 of different specifications. The adjustment is simpler and more convenient, and the installation efficiency is improved. By installing one end of the first adjustment bracket 322 and the second adjustment bracket 323 on the adjustment holes 325 at different positions, the horizontal position of their upper limit member 31 can be changed, thereby changing the distance and tilt angle between the two limit members 31, so as to be suitable for the installation of more metal busbar drums 2 of different specifications, further expanding the scope of application and making the operation more diversified and multifaceted.

[0027] Please see Figures 1 to 4 In some embodiments, the locking member 324 includes a pin 3241 and a first stop 3242. Multiple pins 3241 pass through adjustment holes 325 at different positions to fix one end of the first adjustment bracket 322 and the second adjustment bracket 323 on the mounting base 321. The first stop 3242 is provided at both ends of the pin 3241 to restrict the axial movement of the pin 3241.

[0028] This application uses multiple pins 3241 passing through adjustment holes 325 at different positions to fix one end of the first adjustment frame 322 and the second adjustment frame 323 to the mounting base 321. This fixing method is stable and reliable, facilitates adjustment, and can withstand large forces, ensuring the overall structural stability of the adjustment component 32. Simultaneously, first stoppers 3242 are provided at both ends of the pins 3241, effectively limiting the axial movement of the pins 3241 and preventing them from loosening or falling off during equipment operation. This further ensures the normal operation of the adjustment component 32, allowing the limiting member 31 to stably maintain the adjusted tilt angle, thereby continuously providing a reliable lateral limiting effect for the metal busbar drum 2.

[0029] The first stop 3242 can be a nut tightened at both ends of the pin 3241. After clamping, it can improve the stability of the pin 3241, reduce the shaking of the pin 3241, and extend its service life. The first stop 3242 can also be a stop pin passing through both ends of the pin 3241. Then, the pin 3241 is limited in the adjustment hole 325 by the shape of the stop pin being larger than the diameter of the adjustment hole 325, which improves the stable fit between the pin 3241 and the adjustment hole 325, thereby improving the firmness and safety of the adjustment component 32.

[0030] Please see Figures 1 to 4 In some embodiments, the limiting member 31 includes: a roller 311, a first rotating seat 312 and a second rotating seat 313. The roller 311 is rotatably connected between the first rotating seat 312 and the second rotating seat 313. The roller 311 is tangent to the outer surface of the metal busbar drum 2. The first rotating seat 312 is rotatably connected to the first adjusting frame 322 and the second rotating seat 313 is rotatably connected to the second adjusting frame 323.

[0031] This application rotatably connects roller 311 between the first rotating seat 312 and the second rotating seat 313, with roller 311 tangential to the outer surface of the metal busbar 2. This allows roller 311 to rotate flexibly with the thermal expansion and contraction of the metal busbar 2. When the metal busbar 2 expands due to heat, roller 311 rolls in the direction of expansion, reducing resistance while maintaining close contact and providing lateral restraint. When the metal busbar 2 cools and contracts, roller 311 rolls in the direction of contraction. Throughout the process, the metal busbar 2 remains within the accommodating space 4, thus providing continuous and stable lateral restraint. The first adjusting bracket 322 and the second adjusting bracket 323 can rotate around their respective first rotating seat 312 and second rotating seat 313, making it easier to install the first adjusting bracket 322 and the second adjusting bracket 323 onto the mounting seat 321. This allows the limiting member 31 to better adapt to the different tilt angles adjusted by the adjusting member 32, ensuring that the contact state between the limiting member 31 and the metal busbar drum 2 is always good, and further improving the limiting effect and stability of the metal busbar drum 2.

[0032] Please see Figures 1 to 4 In some embodiments, the limiting member 31 further includes an insulating sleeve 314 disposed on the outside of the roller 311, and the insulating sleeve 314 is provided with an anti-slip groove 315.

[0033] This application provides an insulating sleeve 314 on the outside of the roller 311. The insulating sleeve 314 provides insulation, effectively isolating the metal busbar drum 2 from potential electrical connections with the external environment, preventing safety accidents caused by leakage, and improving the overall safety of the metal busbar drum 2 during operation. The anti-slip groove 315 on the insulating sleeve 314 increases the friction between the roller 311 and the metal busbar drum 2. When the metal busbar drum 2 undergoes thermal expansion and contraction, the roller 311 can better follow the deformation of the metal busbar drum 2, reducing slippage and ensuring that the roller 311 always maintains close contact with the metal busbar drum 2, continuously and stably performing its lateral limiting function. This further ensures the stability of the metal busbar drum 2 during operation, reduces the probability of malfunctions caused by displacement or shaking of the metal busbar drum 2, extends the service life of the equipment, and reduces maintenance costs. Furthermore, the insulating sleeve 314 reduces external corrosion of the roller 311, extends the service life of the roller 311, has a simple structure, is easy to process and install, reduces manufacturing costs, and is suitable for more usage environments.

[0034] Please see Figures 1 to 4In some embodiments, the anti-lateral stretching device for the metal busbar drum further includes a pressing member 5 that cooperates with the support frame 1 to limit the longitudinal movement distance of the metal busbar drum 2. The pressing member 5 is in contact with the top arc of the metal busbar drum 2, and the two ends of the pressing member 5 are respectively installed on the support frame 1 on both sides of the metal busbar drum 2.

[0035] This application provides a pressing member 5 that cooperates with the support frame 1 to limit the longitudinal movement distance of the metal busbar drum 2. The pressing member 5 is in contact with the top arc of the metal busbar drum 2. The two ends of the pressing member 5 are respectively installed on the support frames 1 on both sides of the metal busbar drum 2. The two ends of the pressing member 5 slide and are limited on the support frames 1 on both sides of the metal busbar drum 2. During the operation of the metal busbar drum 2, the two ends of the pressing member 5 slide on the support frame 1. When the metal busbar drum 2 is heated and expands, the two ends of the pressing member 5 can play a certain buffering role, so that the metal busbar drum 2 and the pressing member 5 move upward slightly together, thereby preventing the metal busbar drum 2 from cracking. However, when the metal busbar drum 2 experiences significant displacement due to external environmental factors, the pressing component 5, with its ends constrained on the support frame 1, exerts a reverse pressing force through its contact with the arc at the top of the metal busbar drum 2. This effectively restricts the movement of the metal busbar drum 2, preventing it from colliding with other components or detaching from the accommodating space 4 due to excessive movement caused by external factors, thus further ensuring the stable operation of the metal busbar drum 2. Simultaneously, this limiting method does not excessively hinder the normal thermal expansion and contraction process of the metal busbar drum 2. When the metal busbar drum 2 expands due to heat or contracts due to cooling, the sliding of the pressing component 5 on the support frame 1 adapts to the diameter changes of the metal busbar drum 2, maintaining a stable limiting effect. This ensures that the metal busbar drum 2 does not experience excessive displacement in the longitudinal direction, thereby improving the reliability and safety of the entire metal busbar drum anti-lateral stretching device, extending the service life of the metal busbar drum 2 and related equipment, reducing the risk of malfunctions caused by the displacement of the metal busbar drum 2, reducing maintenance costs and downtime, and improving production efficiency.

[0036] Among them, the pressing component 5 has a simple structure, is easy to install, and can be adjusted and adapted according to different specifications of metal busbar drum 2. It has strong versatility and practicality, and reduces maintenance costs.

[0037] Please see Figures 1 to 5 In some embodiments, the pressing member 5 includes: a flexible part 51, a rigid connecting part 52, and a second stop 53. The rigid connecting part 52 is detachably mounted on both ends of the flexible part 51, and the rigid connecting part 52 is detachably mounted on the support frame 1 through the second stop 53.

[0038] This application detachably mounts the rigid connecting portion 52 to both ends of the flexible portion 51, and the rigid connecting portion 52 is detachably mounted on the support frame 1 via the second stop 53. When limiting the movement of metal busbar drums 2 of different specifications, flexible portions 51 of different sizes or shapes can be easily replaced to adapt to changes in the arc at the top of the metal busbar drum 2. Simultaneously, the versatility of the rigid connecting portion 52 ensures that it can be connected to various types of support frames 1, and the connection to the support frame 1 is more secure, facilitating installation. The flexible portion 51 can deform to a certain extent according to the expansion or contraction of the metal busbar drum 2. When the metal busbar drum 2 expands due to heat, the flexible portion 51 can extend slightly accordingly, without exerting excessive pressure on the metal busbar drum 2, thus avoiding affecting its normal expansion. When the metal busbar drum 2 cools and contracts, the flexible portion 51 can return to its original shape, continuously maintaining contact with the arc at the top of the metal busbar drum 2, providing stable longitudinal limiting. The rigid connection 52 serves to stabilize the connection, ensuring that the flexible part 51 can be accurately installed in the designated position on the support frame 1. The detachable installation method of the second stop 53 further facilitates the installation, debugging and maintenance of the pressing part 5, improves the flexibility and operability of the entire metal busbar anti-lateral stretching device, reduces the cost of use and improves work efficiency.

[0039] The flexible part 51 can be made of steel wire rope, cable or elastic rope, thus making it suitable for more usage environments, expanding the scope of application, and making it simpler and more convenient to operate.

[0040] Please see Figures 1 to 5 In some embodiments, the pressing member 5 further includes an elastic member 54, which is disposed between the second stop member 53 and the support frame 1.

[0041] This application incorporates an elastic element 54 between the second stop 53 and the support frame 1. When the metal busbar drum 2 expands slightly upward due to heat, the elastic element 54 is compressed, providing a buffering effect and further reducing the compressive force on the metal busbar drum 2 during expansion. This prevents damage to the metal busbar drum 2 or disruption of its normal expansion process due to excessive compressive force. When the metal busbar drum 2 cools and contracts, the elastic element 54 returns to its original shape, pushing the second stop 53 and the rigid connection 52 downward as the metal busbar drum 2 contracts. This maintains close contact between the flexible part 51 and the arc at the top of the metal busbar drum 2, continuously providing stable longitudinal restraint. Furthermore, the elastic element 54 can absorb vibration energy generated during the operation of the metal busbar drum 2 to a certain extent, reducing damage to the metal busbar drum 2 and related components caused by vibration. This further ensures the stable operation of the metal busbar drum 2, extends the service life of the equipment, reduces maintenance costs, and improves the reliability and safety of the entire metal busbar drum anti-lateral stretching device. It is suitable for more operating environments, further expanding its applicability.

[0042] Among them, the elastic component 54 can be made of elastic components such as springs and rubber pads, which can be flexibly selected according to the actual use environment and needs, thus making it suitable for different use environments and reducing installation and maintenance costs.

[0043] Please see Figures 1 to 5 In some embodiments, a connecting sleeve 55 is provided at one end of the rigid connecting part 52, and a flexible part 51 is disposed in the connecting sleeve 55. A bolt 56 passes through the connecting sleeve 55 and the flexible part 51, limiting the flexible part 51 in the connecting sleeve 55.

[0044] This application provides a connecting sleeve 55 at one end of the rigid connecting part 52, and places the flexible part 51 inside the connecting sleeve 55. A bolt 56 passes through the connecting sleeve 55 and the flexible part 51, securely limiting the flexible part 51 within the connecting sleeve 55. This connection method, where the connecting sleeve 55 and bolt 56 work together, is not only simple in structure but also provides a strong and reliable connection, effectively preventing the flexible part 51 from falling off or shifting during use, ensuring the stability and reliability of the overall structure of the pressed part 5. Furthermore, this connection method facilitates the installation and removal of the flexible part 51. When it is necessary to replace the flexible part 51 with one of different sizes or shapes, simply loosen the bolt 56, remove the flexible part 51 from the connecting sleeve 55, install the appropriate flexible part 51, and tighten the bolt 56. This convenient and labor-saving operation reduces labor intensity and improves work efficiency. The connecting sleeve 55, fitted onto the end of the flexible part 51, also provides some protection to the flexible part 51, reducing external corrosion, extending its service life, and lowering maintenance costs.

[0045] The flexible part 51 can be equipped with a sling at its end. After the sling is inserted into the connecting sleeve 55, the flexible part 51 can be firmly installed in the connecting sleeve 55 by simply using a bolt 56 to pass through the connecting sleeve 55 and the sling. This makes the operation simpler and more convenient, and reduces labor intensity.

[0046] Please see Figures 1 to 5 In some embodiments, multiple sets of limiting components 3 with different tilt angles are provided on both sides of the metal busbar 2.

[0047] This application, by providing multiple sets of limiting components 3 with different tilt angles on both sides of the metal busbar 2, can laterally limit the metal busbar 2 from multiple directions and angles, further enhancing the limiting effect. The limiting components 3 with different tilt angles can be flexibly arranged according to the actual installation position and operational requirements of the metal busbar 2 to adapt to various complex working conditions. When the metal busbar 2 deforms due to thermal expansion and contraction or other factors, the multiple sets of limiting components 3 can work together to evenly distribute the force, preventing damage to the metal busbar 2 due to excessive local stress, further extending the service life of the metal busbar 2, and making it suitable for more operating environments.

[0048] When the metal busbar drum 2 is bent, multiple sets of limiting components 3 with different inclination angles can ensure that each set of limiting components 3 is in close contact with the metal busbar drum 2. Furthermore, by changing the inclination angle of each set of rollers 311, different positions of the metal busbar drum 2 can be supported to different heights. This achieves lateral limiting while also allowing for targeted settings for metal busbar drums 2 of different specifications. It has strong versatility and adaptability, making it suitable for different installation environments and further expanding the applicability of the device.

[0049] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
