Abstract
Description
Technical Field
[0001] This utility model relates to the field of damping spacer technology, specifically to a four-split damping spacer. Background Technology
[0002] Split conductors are used for transmitting electrical energy in high-voltage transmission lines. Spacer bars, as auxiliary hardware for split conductors, are mainly used to prevent cross-conduction between sub-conductors, suppress aerobatic vibrations, and suppress secondary span oscillations. Depending on the transmission line grade and the number of split conductors, spacer bars are currently classified into five types: those for two, three, four, six, and eight conductors. The proper use of spacer bars is crucial to the safe operation of transmission lines. Traditional four-split damping spacer bars have many limitations in addressing these issues, making it difficult to accurately adapt to complex and varied conductor distributions and to effectively adjust conductor positions to maintain optimal spacing under different operating conditions. Therefore, this utility model was developed to solve these problems. Utility Model Content

By utilizing the cooperation of the bidirectional lead screw, slider, and cantilever in the adjusting structure, the stabilizing structure and the position of the conductor can be adjusted to adapt to different conductor distribution requirements.

In use, when it is necessary to adjust the four-split wire... During position adjustment and stabilization, the bidirectional lead screw 21 is rotated by the rotating rod 24 in the adjustment structure 2. Since the bidirectional lead screw 21 is rotatably connected to the inner wall of the protective shell 1 and its outer wall is threadedly connected to the slider 22, the slider 22 will move relative to the lead screw axis during the rotation of the bidirectional lead screw 21. The cantilever 23 fixed to the outer wall of the slider 22 also moves accordingly. The outer wall of the cantilever 23 is slidably connected to the inner wall of the protective shell 1 to ensure the stability and directionality of its movement. The inner wall of the cantilever 23 is rotatably connected to the outer wall of the connecting block 31, thereby driving the entire stabilizing structure 3 to adjust its position to adapt to different conductor distribution requirements.

During use, the connecting block 31 and the stabilizing block 32 in the stabilizing structure 3 are fixedly connected by fastening bolts 34, and a buffer device 33 is slidably connected to their outer walls. The rubber damping sheet 331 serves as the main damping element. When the conductor vibrates or is displaced by other external forces, the rubber damping sheet 331 will be compressed or stretched. Its own elasticity and internal friction characteristics can... Absorbing and dissipating energy, reducing the amplitude of conductor vibration, the fixing plate 332 is fixed to the outer wall of the rubber damping plate 331. One end of the buffer spring 333 is connected to the fixing plate 332, and the other end is fixed to the outer wall of the connecting block 31 and the stabilizing block 32. When the conductor vibrates, the buffer spring 333 will further assist in buffering and work together with the rubber damping plate 331 to enhance the damping effect. The outer wall of the buffer rod 334 is slidably connected to the inner wall of the connecting block 31 and the stabilizing block 32.

[0025] Working principle:
[0026] When the position of the four-split conductor needs to be adjusted and stabilized, the bidirectional lead screw 21 is rotated by the rotating rod 24 in the adjustment structure 2. Since the bidirectional lead screw 21 is rotatably connected to the inner wall of the protective shell 1 and its outer wall is threadedly connected to the slider 22, the slider 22 will move relative to the lead screw axis during the rotation of the bidirectional lead screw 21. The cantilever 23 fixed to the outer wall of the slider 22 also moves accordingly. The outer wall of the cantilever 23 is slidably connected to the inner wall of the protective shell 1 to ensure the stability and directionality of its movement. The inner wall of the cantilever 23 is rotatably connected to the outer wall of the connecting block 31, thereby driving the entire stabilizing structure 3 to adjust its position to adapt to different conductor distribution requirements.
[0027] In use, the connecting block 31 and the stabilizing block 32 in the stabilizing structure 3 are fixedly connected by fastening bolts 34. A buffer device 33 is slidably connected to the outer wall of the two. The rubber damping plate 331 serves as the main damping element. When the conductor vibrates or is displaced by other external forces, the rubber damping plate 331 will be squeezed or stretched. Its own elasticity and internal friction characteristics can absorb and dissipate energy, reducing the vibration amplitude of the conductor. The fixing plate 332 is fixed to the outer wall of the rubber damping plate 331. One end of the buffer spring 333 is connected to the fixing plate 332, and the other end is fixed to the outer wall of the connecting block 31 and the stabilizing block 32. When the conductor vibrates, the buffer spring 333 will further assist in buffering and work together with the rubber damping plate 331 to enhance the damping effect. The outer wall of the buffer rod 334 is slidably connected to the inner wall of the connecting block 31 and the stabilizing block 32. Its function is to limit the movement direction of the buffer device 33 and ensure the stability and reliability of the buffering process.
