Laser cleaning device for foreign matters of power grid

Abstract

The invention discloses a laser cleaning device for foreign matters of a power grid. The device comprises a laser emitting unit, an imaging unit, a display control unit and a horizontal and pitching angle adjusting mechanism, wherein an emergent light axis of the laser emitting unit is parallel to an imaging optical axis of the imaging unit; the imaging unit is used for collecting images of a to-be-cleaned area; the display control unit is used for displaying the images of the to-be-cleaned area in real time, controlling the horizontal and pitching angle adjusting mechanism to drive the laseremitting unit and the imaging unit to synchronously move and control the laser emitting unit to output a laser beam in response to operations of a user in order to make the laser beam emitted by the laser emitting unit move back and forth along a path freely set by the user. According to the device, accurate laser ablation cutting of the foreign matters of the power grid can be achieved, and the foreign matters of the power grid can be effectively cleaned.

Description

technical field [0001] The invention relates to the field of laser technology. More specifically, it relates to a power grid foreign matter laser cleaning device. Background technique [0002] Foreign objects such as kites, plastic bags, and nylon ropes are easy to attach to high-voltage wires. Foreign objects will cause short circuits in high-voltage wires in thunderstorms and other weather, causing power supply network paralysis and huge economic losses. In order to avoid the adverse effects of entangled foreign matter on the high-voltage wires, it is necessary to clean up the foreign matter on the high-voltage wires in time. The traditional methods are mostly to manually climb up the pole tower for cleaning, lift off the insulating bucket arm truck, and clean the drone with fire. There are safety hazards. Laser has the characteristics of good directionality and high energy density. It can be used to burn and clean foreign matter on high-voltage wires to avoid personnel ...

AI Technical Summary

Problems solved by technology

In order to ensure that the limited power laser can effectively ablate the foreign matter on the power grid, the diameter of the spot on the foreign matter should be within the order of centimeters, and the size of some foreign matter is tens or even hundreds of centimeters, and it cannot be effectively cleaned by only burning a few centimeters of the foreign matter foreign body

At present, several implementation methods and existing problems of power grid foreign matter laser cleaning devices are as follows: 1) Most foreign matter cleaning systems are designed to clean large-sized foreign matter by adjusting the emission direction of the emission system. In order to avoid the impact of laser on high-voltage cables Foreign objects need to be cut along the edge of the cable

Since the cable has a certain radian, the cutting lines required at different angles are flexible and changeable, and the cleaning is mostly manual adjustment with human participation, which makes the change of the laser emission direction of the emission system incoherent, and the accumulation of laser light at different positions on distant foreign objects The energy is different, it is difficult to achieve continuous and effective cutting

In addition, due to the existence of factors such as strong winds, the imbalance of energy accumulation is further increased.

2) The cost of precise tracking of fast mirrors is high, the volume and weight are large, and fire will affect the tracking effect, and the image processing algorithm has poor adaptability to different targets and scenes

[0004] In addition, the working distance of the power grid laser foreign object cleaning system is usually 100 to 200 meters, and it is difficult to accurately aim when cleaning small objects such as cloth strips and kite strings.
