Problems solved by technology

[0003] The cleaning of foreign objects on high-voltage lines is currently mainly done by manual and online robots. The manual method is inefficient and poses a threat to the safety of personnel; online robots have a high degree of automation, but there are also inspection operations that cannot be performed on large-scale and long-distance lines; in recent years In the future, with the miniaturization of sensors and the improvement of flight control systems, UAV technology has developed rapidly, and UAVs have been widely used in various fields, which also provides new ideas for inspection operations of power transmission lines. and technical methods

Embodiment Construction

[0033] The following descriptions of various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the present invention can be implemented.

[0034] The invention provides a laser ablation obstacle removal device, such as figure 1 , the structure of one embodiment may include: a low-power fiber laser 1 . As an example, the low-power fiber laser 1 of the present invention can be installed at the tail of the laser ablation obstacle removal device. The low-power fiber laser 1 includes a laser seed source 10 , a fiber pre-amplification stage 2 and a fiber power amplification stage 3 . As an example, the laser seed source 10 of this embodiment is used to generate signal light, and it can be a low-power continuous thulium-doped fiber laser seed source. After the signal light is sent by the laser seed source 10, it is transmitted to the optical fiber pre-amplification stage 2 for amplification. As an example, the optical fiber pre-amplification...

Abstract

The invention provides a laser ablation obstacle removing apparatus. The laser ablation obstacle removing apparatus comprises a low-power optical fiber laser, an indicating laser, a high-transmittancehigh reflector, a first full moon scimitar-shaped lens and a second full moon scimitar-shaped lens, wherein the low-power optical fiber laser comprises a laser seed source, an optical fiber pre-amplification stage (a semiconductor laser pumping source, a light beam coupler and first gain dielectric optical fibers) and an optical fiber power amplification stage (a semiconductor laser pumping source, a light beam coupler and second gain dielectric optical fibers). The laser ablation obstacle removing apparatus is hoisted on an unmanned aerial vehicle through a damping bolt, so that foreign matters on a high altitude power transmission line can be removed by ablation in long-distance manner.

Description

technical field [0001] The invention relates to the technical field of obstacle removal for high-altitude power transmission lines, in particular to a laser ablation obstacle removal device. Background technique [0002] The transmission line is an important part of the power grid, and regular inspection of the transmission line is a basic work to effectively ensure the safe operation of the transmission line and its equipment. Overhead transmission lines often have icing, floating objects, etc., which greatly affect the safe operation of the power grid. Regular inspections must be carried out on the transmission lines to keep abreast of and understand the operation of the transmission lines in order to detect and eliminate hidden dangers in time and prevent accidents. Ensure the safety of power supply. In order to ensure the normal operation of the power system, lines and facilities, it is necessary to regularly clean up the foreign objects on the power lines and facilitie...
