Description

Technical Field

[0001] This utility model belongs to the field of suspension strings, specifically relating to suspension strings for ultra-high voltage overhead lines. Background Technology

[0002] Ultra-high voltage overhead lines refer to power transmission lines with voltage levels of 1000kV and above. These lines have advantages such as large transmission capacity, long transmission distance, and low line loss, and are an indispensable part of modern power systems. Suspension strings are important components in overhead transmission lines used to connect and support conductors. They are usually composed of multiple insulators, connecting hardware, and conductor clamps, and can suspend the conductors on the tower and keep them in a horizontal position.

[0003] Suspension strings suspend conductors from towers via insulators and connecting hardware, ensuring the conductors' vertical stability. The design of the suspension strings maintains a certain tension in the horizontal direction, preventing the conductors from shifting due to wind or other external forces. However, after winter, suspension strings are often covered with ice, sometimes requiring manual removal of the ice from the outer wall. In existing technology, it is difficult to quickly remove the ice from the outer wall of the suspension strings when they are being removed, and excessive removal can easily damage the suspension strings, requiring further improvement.

[0004] Therefore, a suspension string for ultra-high voltage overhead lines was proposed, which can cause the ice on the outer wall of the suspension string to fall off quickly when it is struck, thus improving the protection of the suspension string. Utility Model Content

[0005] To overcome the problem that existing suspension strings are difficult to quickly remove ice from their outer walls when struck, and that excessive striking can easily damage the suspension strings, a new suspension string for ultra-high voltage overhead lines is proposed.

[0006] The technical solution of this utility model is as follows: a suspension string for ultra-high voltage overhead lines, including a connecting rod; an upper suspension plate is fixedly connected to the upper side wall of the connecting rod, a lower suspension plate and a counterweight are fixedly connected to the lower side wall of the upper suspension plate, the counterweight is located below the lower suspension plate, multiple extended wings are fixedly connected to the middle side wall of the connecting rod, the multiple extended wings are located between the upper suspension plate and the lower suspension plate, three evenly distributed bearing blocks are fixedly connected to the upper end of the extended wings, a second groove is opened at the upper end of the bearing block, a fixing block is fixedly connected to the inner wall of the second groove, a through hole is opened at the upper end of the integral structure formed by the bearing block and the fixing block, a vibration mechanism is provided on the inner wall of the through hole, a locking mechanism for locking the lower end of the vibration mechanism is provided at the upper end of the lower suspension plate, and a suspension block is fixedly connected to the upper end of the connecting rod.

[0007] Preferably, during use, the vibration mechanism is installed on the inner wall of the through hole, so that the lower end of the vibration mechanism and the upper end of the locking mechanism are in contact. The locking mechanism is then used to lock the vibration mechanism. When ice covers the outer wall of the device in winter, the ice can be vibrated by turning on the vibrator after the weather clears up, which helps to quickly remove the ice from the outer wall of the device. This solves the problem in the prior art that when the suspension string is hit, it is difficult to make the ice on the outer wall of the suspension string fall off quickly, and excessive hitting can easily damage the suspension string.

[0008] Preferably, the end of the bearing block away from the center of the connecting rod is located outside the extended fin, and the end of the second groove away from the connecting rod passes through the end of the bearing block away from the connecting rod.

[0009] Preferably, the vibration mechanism includes an upper mounting plate, a vibrating rod, and a lower mounting plate; the upper mounting plate is placed at the upper end of the uppermost of the multiple extended wings, and the upper end of the upper mounting plate has three evenly distributed first insertion holes through it, with the vibrating rod slidingly disposed on the inner wall of the first insertion holes; the lower mounting plate is placed at the lower end of the lowermost of the multiple extended wings, and the upper end of the lower mounting plate has three evenly distributed second insertion holes through it, with the lower end sidewall of the vibrating rod slidingly disposed on the inner wall of the second insertion holes.

[0010] Preferably, a first nut is threaded onto the upper side wall of the vibrator, and the lower end of the first nut fits against the upper end of the upper mounting plate.

[0011] Preferably, a second nut is threaded onto the lower part of the side wall of the vibrator, and the upper end of the second nut fits into the lower end of the lower mounting plate.

[0012] Preferably, the locking mechanism includes threaded posts and long nuts. Three evenly distributed threaded posts are fixed to the upper end of the lower suspension plate. Long nuts are threadedly installed on the upper side wall of the threaded posts. The upper inner wall of the long nuts is threadedly connected to the lower side wall of the vibrator.

[0013] Preferably, the upper edge of the upper suspension plate has three evenly distributed first grooves, which correspond to the second grooves in the vertical direction.

[0014] The beneficial effects of this utility model are as follows: By installing the vibration mechanism on the inner wall of the through hole, the lower end of the vibration mechanism and the upper end of the locking mechanism are fitted together, and the locking mechanism is used to lock the vibration mechanism. When ice covers the outer wall of the device in winter, the ice can be vibrated by turning on the vibrator after the weather clears up, which helps to remove the ice from the outer wall of the device quickly. This solves the problem in the prior art that when the suspension string is hit, it is difficult to make the ice on the outer wall of the suspension string fall off quickly, and excessive hitting can easily damage the suspension string.

[0023] In use, the vibration mechanism is installed on the inner wall of the through hole 10, so that the lower end of the vibration mechanism and the upper end of the locking mechanism are in contact. The locking mechanism is then used to lock the vibration mechanism. When ice covers the outer wall of the device in winter, the ice can be vibrated by turning on the vibrator 14 after the weather clears up, which helps to quickly remove the ice from the outer wall of the device.

[0024] Please see Figure 1 and Figure 2 In this embodiment, the end of the bearing block 7 away from the center of the connecting rod 1 is located outside the extended wing 4, and the end of the second groove 8 away from the connecting rod 1 passes through the end of the bearing block 7 away from the connecting rod 1. When the ice covers the side wall of the bearing block 7, since a part of the bearing block 7 is located outside the extended wing 4, it is convenient to shake the ice off.

[0025] Please see Figure 1 and Figure 4 In this embodiment, the vibration mechanism includes an upper mounting plate 13, a vibrating rod 14, and a lower mounting plate 15. The upper mounting plate 13 is placed on the upper end of the uppermost of the multiple extended wings 4. The upper end of the upper mounting plate 13 has three evenly distributed first insertion holes. The vibrating rod 14 is slidably disposed on the inner wall of the first insertion hole. The lower end of the lowermost of the multiple extended wings 4 has a lower mounting plate 15 placed on the lower end of the lower mounting plate 15. The upper end of the lower mounting plate 15 has three evenly distributed second insertion holes. The lower end sidewall of the vibrating rod 14 is slidably disposed on the inner wall of the second insertion hole. By placing the vibrating rod 14 on the inner walls of the first insertion hole and the second insertion hole at the same time, the vibrating rod 14 can be placed quickly and stably.

[0026] Please see Figure 1 and Figure 4 In this embodiment, a first nut 16 is threadedly installed on the upper side wall of the vibrating rod 14. The lower end of the first nut 16 fits against the upper end of the upper mounting plate 13. By threading the first nut 16 onto the upper side wall of the vibrating rod 14, the vibrating rod 14 can be locked.

[0027] Please see Figure 1 and Figure 4 In this embodiment, a second nut 17 is threadedly installed on the lower part of the side wall of the vibrating rod 14.

Three evenly distributed threaded posts 11 are fixed to the upper end of the lower suspension plate 5. Long nuts 12 are threadedly installed on the upper part of the side wall of the threaded posts 11. The upper part of the inner wall of the long nut 12 is threadedly connected to the lower side wall of the vibrating rod 14. When it is necessary to lock the lower side wall of the vibrating rod 14, the long nut 12 is manually rotated so that the upper part of the inner wall of the long nut 12 is threadedly installed on the lower part of the side wall of the vibrating rod 14, thereby quickly and stably locking the vibrating rod 14.

[0029] Please see Figure 1 and Figure 4 In this embodiment, three evenly distributed first grooves 3 are provided through the upper edge of the upper suspension plate 2. The first grooves 3 correspond to the second grooves 8 in the vertical direction. When the vibrator 14 needs to be removed, the first nut 16 and the second nut 17 are removed, and the vibrator 14 can be manually removed upward through the first grooves 3, which facilitates the maintenance and replacement of the vibrator 14.

[0030] Working principle: First, the vibration mechanism is installed on the inner wall of the through hole 10, so that the lower end of the vibration mechanism and the upper end of the locking mechanism are in contact. Specifically, the vibrating rod 14 is placed on the inner wall of the first insertion hole and the second insertion hole at the same time. Then, the first nut 16 is threaded onto the upper part of the side wall of the vibrating rod 14, so that the lower end of the first nut 16 is in contact with the upper end of the upper mounting plate 13. The second nut 17 is threaded onto the side wall of the vibrating rod 14, so that the upper end of the second nut 17 is in contact with the lower end of the lower mounting plate 15.

[0031] When it is necessary to lock the lower side wall of the vibrator 14, manually rotate the long nut 12 so that the upper inner thread of the long nut 12 is installed on the lower side wall of the vibrator 14, which can quickly and stably lock the vibrator 14.

[0032] When ice covers the outer wall of the device in winter, the ice can be vibrated by turning on the vibrator 14 after the weather clears up, which helps to remove the ice from the outer wall of the device quickly. This allows the ice on the outer wall of the suspension string to fall off quickly when it is struck.

[0033] When the vibrator 14 needs to be removed, after removing the first nut 16 and the second nut 17, the vibrator 14 can be manually removed upward through the first groove 3, which facilitates the maintenance and replacement of the vibrator 14.
