Mechanical shock deicing device for overhead ground wire and using method thereof

Abstract

The invention discloses a mechanical shock deicing device for an overhead ground wire and a using method thereof. One end of a piston rod in a deicing mechanism is connected with an icebreaking head, while the other end passes through an end cover to connect a piston head in a piston cylinder; the end cover is fixed on the upper end face of the piston cylinder; a pulling rope ring is arranged on the upper end face of the piston cylinder; the piston rod in the piston cylinder is sleeved with a spring; the lower end face of the piston cylinder is communicated with a piston cavity in a connecting body; the connecting body is connected with a trigger mechanism; the connecting body is provided with a tail rope ring close to the piston cylinder; and a clamping mechanism is at least two limit rods fixed on the upper part of the icebreaking head. When the mechanical shock deicing device is used, the limit rods clamp the overhead ground wire or an OPGW optical cable, a pulling rope and a tail rope are pulled to make the piston rod vertical to the overhead ground wire or the OPGW optical cable, and the trigger mechanism is started to shock for deicing. The device and the using method have the advantages of firm clamping, strong controllability, concentrated deicing force, and good deicing effect.

Description

technical field [0001] The invention relates to a mechanical vibrating deicing device, in particular to a mechanical vibrating deicing device for overhead ground wires and a method for using the same, and is particularly suitable for deicing overhead ground wires or OPGW optical cables. Background technique [0002] At present, the main method of melting ice for overhead transmission lines in the world is high-current melting or short-circuit melting. However, the inherent parameter design of transmission line equipment in my country determines that this method is not suitable for use in my country, and other deicing methods can only be adopted. . [0003] The Chinese patent authorization announcement number is CN201247941Y, and the utility model patent on May 27, 2009 discloses a mechanical vibration deicing device for overhead ground wires. One end of the sleeve in the device is fixed on the ground wire chuck. Below and corresponding to the ground wire, a piston is install...

AI Technical Summary

Problems solved by technology

Although this kind of deicing device will not cause damage to the overhead line, the explosive package inside it is easy to get wet, the separation of the explosion is not strong, it is easy to produce continuous explosions, and the control is weak, and it is difficult to hang the device. It is not easy to be perpendicular to the overhead ground wire, so the deicing force is scattered and the efficiency is not high
