Transmission line foreign matter cleaning head

Abstract

The invention discloses a transmission line foreign matter cleaning head, which belongs to the technical field of foreign matter cleaning. The problem of easy knife entanglement and low work efficiency during the use of existing equipment is solved. The foreign matter cleaning head for transmission lines includes a cleaning head body and a bracket. The cleaning head body includes a shell and knives arranged at both ends of the shell. The knife holder includes a small knife holder and a large knife holder. The small knife holder is fixed on the rotating shaft. There is a bevel gear I fixed by splines in the middle of the rotating shaft. There are fixed brackets perpendicular to the rotating shaft on both sides of the bevel gear I. The fixed bracket It is fixed on the casing, and the fixed frame is equipped with a bevel gear II. The bevel gear I and the bevel gear II mesh. The large tool holder is fixed on the hollow shaft. One end of the hollow shaft meshes with the bevel gear II, and the other end is set on the rotating shaft through a bearing. On the knife holder, a small knife is provided on the small knife holder, and a large knife is provided on the large knife holder. The cutting heads of the small knife and the large knife are bent in opposite directions. The invention can be used to clean foreign matter in transmission lines.

Description

technical field [0001] The invention relates to a foreign matter cleaning head for power transmission lines, which belongs to the technical field of foreign matter cleaning. Background technique [0002] With the rapid development of the power grid and the continuous improvement of users' requirements for power supply reliability, higher requirements are put forward for the safety and reliability of power grid operation. However, when kites, plastic bags, Kongming lanterns and other foreign objects are inevitably entangled on the transmission line, it may cause short-circuit tripping of the transmission line and substation. The traditional foreign matter treatment methods for wires generally use blowtorch burning, rope hooking, and operating rod extraction, etc., but these methods have a certain degree of destructiveness and limitations, and the work efficiency is low and the time is long. For example, the blowtorch burning method, There is a relatively high risk of damage ...

Problems solved by technology

However, when kites, plastic bags, Kongming lanterns and other foreign objects are inevitably entangled on the transmission line, it may cause short-circuit tripping of the transmission line and substation

The traditional wire foreign matter treatment methods generally use blowtorch burning, rope hooking, operating rod extraction, etc., but these methods have a certain degree of destructiveness and limitations, and the work efficiency is low and takes a long time. For example, the blowtorch burning method, There is damage to the cable sheath, and the risk is relatively high. Methods such as rope hooking and operating rod extraction are low in cleaning efficiency and poor in safety. Especially in severe weather conditions such as thunderstorms and strong winds, it is difficult to ensure the safety of operations.
