One of the core technologies of laser obstacle remover devices is laser cutting. The principle is based on focusing a high-energy-density laser beam onto an extremely small area, generating sufficient shock waves or heat to rapidly melt, vaporize, or ablate materials, thus achieving precise cutting. In the protection of high-voltage power lines, the application of laser cutting technology requires not only high precision but also stable operation in extreme environments. For example, the power density of the laser beam can reach 10^8 to 10^10 watts per square centimeter, enabling laser cutting to complete tasks with extremely high speed and precision when dealing with branches near high-voltage lines while minimizing the impact on the surrounding environment.
In practical applications, the cutting efficiency and accuracy of laser obstacle remover devices are achieved through a series of experiments and optimizations. For instance, by adjusting the frequency and energy of the laser, effective cutting can be performed on branches of different materials and thicknesses. In a case study involving high-voltage lines, the laser obstacle remover device can clear branches up to 10 centimeters in diameter in less than 5 minutes, with an accuracy error of no more than 1 millimeter, significantly enhancing the efficiency and safety of obstacle removal operations.
Moreover, laser cutting technology demonstrates unique advantages in environmental protection and sustainable development. Compared to traditional mechanical cutting or chemical removal methods, laser cutting does not produce harmful chemicals or solid waste, reducing environmental pollution. At the same time, the precise control technology of laser obstacle remover devices ensures minimal material waste, meeting modern environmental and resource-saving requirements. In the context of global climate change and frequent extreme weather events, environmental adaptability testing and optimization of laser obstacle remover devices are particularly important, ensuring stable operation under various climatic conditions and providing strong support for the stable power supply of the grid.
2.Laser Transmission Characteristics in Extreme Environments
In high-voltage line environments, the laser transmission characteristics of laser obstacle remover devices are key factors in their design and application. Electric and magnetic fields in high-voltage environments can interfere with the propagation of laser beams. Therefore, studying the transmission characteristics of lasers under these conditions is crucial for ensuring the accuracy and reliability of laser obstacle remover devices. The scattering and absorption properties of lasers in air also affect their transmission distance and energy density, especially under humid or foggy weather conditions, where the attenuation of laser energy is more pronounced. Through experimental data and case studies, we have found that using specific wavelengths of lasers, such as near-infrared lasers at 1080 nm, can reduce the impact of atmospheric scattering to some extent and improve transmission efficiency under adverse weather conditions.

In the development of the laser obstacle remover—a guardian of high-voltage power grid lines—precise control technology is one of its core competitive advantages. By employing advanced laser cutting techniques, the laser obstacle remover can accurately remove branches and other obstructions that threaten line safety without touching the high-voltage conductors. For example, in an experiment focusing on the precise control technology of the laser obstacle remover, the device achieved cutting with a precision of 1 millimeter within 100 meters of high-voltage lines, a level of accuracy far surpassing traditional mechanical methods. Additionally, by integrating high-resolution cameras and image recognition algorithms, the laser obstacle remover can monitor and analyze the growth of branches in real time, thereby achieving precise planning of the cutting path.

In the development of laser obstacle remover devices, the selection and optimization of the laser generator are critical steps. Considering the special working environment of high-voltage power lines, the laser generator must have high stability and high-energy output characteristics to ensure stable operation under various extreme weather conditions. For example, to address the common issue of tree branch interference on high-voltage lines, we chose a fiber laser generator with a wavelength of 1080 nm, which offers excellent penetration and cutting efficiency. During the optimization process, we adopted an advanced thermal management system to reduce the risk of laser overheating caused by prolonged operation, thereby extending the lifespan of the equipment and maintaining its performance stability.
2.Design and Calibration of the Optical System
During the development of the laser obstacle remover device, the design and calibration of the optical system are crucial for ensuring the equipment performs tasks efficiently and accurately. Given the special environment of high-voltage power lines, the optical system must be able to adapt to extreme weather conditions while maintaining precise focusing and stable transmission of the laser beam. To achieve this, we used a high-power laser generator combined with advanced optical lens assemblies to minimize energy loss and enhance cutting efficiency.
During the design phase, we employed ZEMAX optical design software for simulation to optimize the optical path and ensure the accuracy of the laser beam at different distances and angles. For example, in simulations, we found that by adjusting the focal length of the lenses, the diameter of the laser beam could be controlled to within 500 micrometers, enabling precise cutting of fine branches.
In the design and calibration of the optical system, we not only relied on theoretical models but also conducted extensive experiments and field tests to continuously optimize system performance. Within a range of 10–500 meters, the lens’s focal length was electrically adjusted to form a virtual closed curve, ensuring that the laser obstacle remover device automatically focuses at different distances without manual intervention, reducing operational complexity. This makes it a reliable guardian for high-voltage power lines in practical applications.
