Double-layer vibration-proof hammer

Abstract

The invention relates to the field of transmission lines, in particular to a vibration-proofdevice for high-voltage transmission lines. The technical problem to be solved is to provide a vibration-proof hammer filled with gas and two kinds of damping fluids, which is not liable to be loosened and displaced, can adapt to various vibration frequencies, has the function of warning identification, prevents the aircraft from accidental collision, and can provide the positioning mark for the aircraft. The technical scheme adopted to solve the technical problem is as follows: the double-layer vibration-proof hammer comprises a hammer body, a wire clamp, a steel strand, and a connecting plate. The hammer body is divided into two layers of an upper hammer body and a lower hammer body, the upper hammer body is two, the lower hammer body is two, and the steel strand comprises an upper steel strand and a lower steel strand; the upper steel strand and the lower steel strand are arranged on the connecting plate in parallel; at the joint of the hammer body and the steel strand wire, a waterproof gasket is arranged; The invention is applied to the installation of high-voltage wires.

Description

technical field The invention relates to the field of power transmission lines, in particular to an anti-vibration device for high-voltage power transmission lines. Background technique Because the high-voltage line is higher from the ground, the high-voltage line is longer. When the flowing air encounters a cylindrical high-voltage line, it creates a "Karman vortex" on its rear side. Therefore, the high-voltage line vibrates repeatedly on the vertical plane, causing the high-voltage line to fatigue or even break due to periodic bending, posing a threat to the safe operation of the line and personnel safety, and even causing corresponding damage to the tower. Therefore, a certain number of anti-vibration hammers are generally installed on the high-voltage line to avoid and eliminate the vibration of the high-voltage line, that is, the high-voltage line will drive the anti-vibration hammer to vibrate together when the high-voltage line vibrates, thereby consuming the vibrati...

AI Technical Summary

Problems solved by technology

However, due to the long-term vibration of the traditional anti-vibration hammer for transmission lines, the clamp is easy to loosen, which causes the anti-vibration hammer to slide and shift on the high-voltage transmission line, and the anti-vibration effect is weakened; the traditional damping liquid anti-vibration hammer only has one One kind of damping fluid, poor anti-vibration effect, unable to adapt to multiple frequencies, unable to adapt to different wind forces

Moreover, traditional power transmission lines lack warning signs. Due to the small diameter and high height of high-voltage lines, and the color is easily confused with the sky background, it is often difficult for staff to see it with the naked eye standing on the ground or in a helicopter. , Helicopters or UAVs cannot judge and see the high-voltage lines clearly, and they are easy to hit the high-voltage lines
