Description

Technical Field

[0001] The invention belongs to the technical field of power line auxiliary equipment, and in particular relates to a split conductor spacing device for a power line. Background Art

[0002] Long-distance, large-capacity ultra-high voltage transmission lines use two, four or more split conductors per phase. The use of split conductors also brings a series of new challenges. Due to the close distance between the split conductors, the split conductors are prone to whipping, wind vibration and oscillation under the influence of natural factors such as wind and temperature. These phenomena may not only cause mechanical damage to the split conductors, but also affect the electrical performance of the power line. Therefore, spacers are installed at a certain distance in the span. Existing spacers for power lines mostly adopt a polygonal structure, but the spacer assembly cannot be flexibly adjusted, making it difficult to adjust the distance between the power lines, and it is impossible to quickly and effectively fix the split conductors. In addition, the existing spacer frame and wire clamp connection adopt a hard connection structure. During the dancing of the split conductor, sub-span oscillation and other forms of conductor vibration, the spacer needs to withstand torsional force and bending force from different directions. The hard connection structure collides severely, which is very likely to cause wear and even fracture and damage to the limiting structure at the connection between the wire clamp and the frame. In severe cases, the wire breaks, causing great harm to the operation of the power line. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and to solve the problems raised in the above technical background.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a split conductor spacing device for a power line, which includes a tray, a translation mechanism is arranged on the outside of the tray, an active moving block and a passive moving block are arranged inside the translation mechanism, connecting rods are fixedly arranged on the outside of the active moving block and the passive moving block, a wire clamp is arranged on the outer end of the connecting rod, the wire clamp includes a bottom half ring and a top half ring, positioning holes are correspondingly arranged inside the bottom half ring and the top half ring, a fixing bolt is arranged inside the positioning hole, and a control mechanism is arranged on the inside of the tray.

[0005] The connecting rod is connected to the bottom half ring via a hinge shaft, and a buffer spring is arranged inside the bottom half ring.

[0006] The translation mechanism includes a positioning seat, the active moving block and the passive moving block are cooperatively connected with the positioning seat, a turning rod is arranged between the active moving block and the passive moving block, a first cross bar is arranged on the left side of the turning rod, and a second cross bar is arranged on the right side of the turning rod, and the first cross bar and the second cross bar are cooperatively connected with the active moving block and the passive moving block.

[0007] A limiting groove is arranged inside the positioning seat, and a limiting rod is arranged at the bottom of the passive shifting block.

[0008] A sliding groove is arranged on the surface of the tray, and a sliding rod is arranged at the bottom of the turning rod.

[0009] The first crossbar is higher than the second crossbar.

[0010] The control mechanism includes a gear plate, a driving block and a traction platform. The driving blocks are evenly arranged on the outside of the gear plate. The driving blocks are meshed with the gear plate through side teeth. An upper rack is arranged on the upper side of the driving block, and a lower rack is arranged on the lower side of the traction platform. The upper rack and the lower rack cooperate with each other, and the traction platform is fixedly connected to the active moving block through a connecting block.

[0011] A central hole is arranged inside the driving block, a threaded rod is threadedly arranged inside the central hole, and a control bolt head is fixedly arranged at the end of the threaded rod.

[0012] The present invention provides a split conductor spacing device for power lines, which has the following beneficial effects: when the device is in use, through the design of a translation mechanism, especially the cooperation of an active moving block and a passive moving block, and the linkage of a turning rod, a first cross bar and a second cross bar, the wire clamp can flexibly adjust its position to adapt to split conductors with different spacings. At the same time, the bottom half ring and the top half ring are fastened by a fixing bolt through a positioning hole, thereby ensuring the stable fixation of the split conductors and preventing mutual interference and wear between the split conductors. The design of the threaded rod and the control bolt head allows the user to easily adjust the position of the driving block as needed, thereby changing the spacing of the wire clamp. The limiting groove inside the positioning seat cooperates with the limiting rod at the bottom of the passive moving block, and the sliding groove on the surface of the tray cooperates with the sliding rod at the bottom of the turning rod. These designs enhance the structural stability of the device and prevent the components from being misplaced or falling off during movement. The device reduces mutual interference and electromagnetic induction between the split conductors by effectively separating and fixing the split conductors, thereby improving the efficiency and stability of power transmission. At the same time, the device also helps to reduce the impact of conductor dancing, sub-span oscillation and other forms of vibration on the split conductors, thereby improving the safety and reliability of the line.
