Problems solved by technology
[0002] Electric wires are the main transmission device for electric power. Most of the long-distance transmission high-voltage electric wires are installed overhead, but in windy weather, the wires are easy to shake with the wind, so resonance is very easy to occur, and the resonance of the wires will cause support If the structure is damaged, there will be an open circuit. In addition, some wires have a large arc, and the wires that are closer to each other may contact each other when the wind is strong, resulting in a short circuit. In order to prevent the above situation, we propose An anti-resonance device installed on overhead wires

Embodiment 1
[0028] Embodiment 1, an anti-resonance device installed on overhead wires, when in use, select the number of corresponding fixed points for installation and 1 according to the number of wires, and then connect the U-shaped frame 21 with the arc frame 19, by The wires are clamped inside the U-shaped frame 21 and the arc frame 19, then fixed by the fixing nut 23, and the wires are compressed by the pressing plate 22, thereby ensuring that the inner tube 18 can drive the wires to move. When the wind blows, the wind drives the fan blade frame 10 to rotate, thereby driving the gear one 11 to rotate, and through the connection between the gear one 11 and the gear two 14, the rotating shaft 12 can be driven to rotate when the fan blade frame 10 rotates. This drives the cam 16 to rotate, and the rotating cam 16 intermittently contacts the top ball 25, driving the piston 26 at the top of the slide bar 24 to perform piston movement in the inside of the outer tube 17. At this time, the ou...

The invention discloses an anti-resonance device mounted on an overhead wire, which comprises a mounting box, a power structure mounted on the side surface of the mounting box, a transmission seat arranged in the mounting box, and a connecting frame for integrally fixing the anti-resonance device on the wire, so that the wires can be supported, and the phenomenon of contact between the wires can be effectively prevented; in strong wind weather, wind drives a fan blade frame to rotate, and a cam on a rotating shaft can be in intermittent contact with a top ball under transmission of a transmission seat, so that a piston I is driven to perform piston motion in an outer pipe, the inner part of the outer pipe is inflated, a piston II is jacked up, and an inner pipe moves outwards; and after reaching the position of the exhaust pipe, the electric wires are reset under the action of the second spring, so that force is applied to the electric wires fixed on the connecting frames, and due to the fact that the time for applying force to the electric wires on the connecting frames is different, the situation of resonance of the electric wires can be effectively prevented.
Description
technical field [0001] The invention relates to the field of anti-resonance technology, in particular to an anti-resonance device installed on overhead wires. Background technique [0002] Electric wires are the main transmission device for electric power. Most of the long-distance transmission high-voltage electric wires are installed overhead, but in windy weather, the wires are easy to shake with the wind, so resonance is very easy to occur, and the resonance of the wires will cause support If the structure is damaged, there will be an open circuit. In addition, some wires have a large arc, and the wires that are closer to each other may contact each other when the wind is strong, resulting in a short circuit. In order to prevent the above situation, we propose An anti-resonance device installed on overhead wires. Contents of the invention [0003] In order to overcome the deficiencies in the background technology, the utility discloses an anti-resonance device install...
