In industries such as power and railways, foreign objects like kite strings, plastic sheets, and tree branches on overhead lines are "invisible killers" that can cause short circuits, tripping, and large-scale power outages. Traditional obstacle removal methods rely on manual pole climbing or power outages for maintenance, which are risky, inefficient, and costly. The HIZ-NT-QZY remote laser obstacle removal device launched by Guangxi Hai Zhuo Technology uses high-energy laser technology to achieve non-contact remote obstacle removal, becoming a new efficient and safe operation and maintenance tool for the industry.
The core principle of the HIZ-NT-QZY remote laser obstacle removal device is to utilize the thermal effect of high-power fiber lasers, emitting laser beams of specific wavelengths, which are precisely focused on the target object through an optical system, causing it to instantly heat up, vaporize, or melt, thus achieving rapid removal. It is equipped with a high-definition visual aiming system, featuring high-magnification optical zoom and digital zoom functions, allowing for clear locking of targets over 100 meters away. Combined with dynamic focusing and coaxial laser indication, its positioning accuracy is extremely high, with an obstacle removal success rate exceeding 98%. During operation, there is no need for power outages or climbing, and the operator can remotely control it from a safe area on the ground, completely avoiding the risks of falling from heights and electric shock.
The remote laser obstacle removal device combines the advantages of high efficiency and convenience. The device has a compact structure, with dimensions of only 660x500x320mm, and can be carried by a single person. It can be set up within 10 minutes and is suitable for various scenarios such as mountainous areas and complex terrains. It can complete obstacle removal within 30 seconds within a 100-meter range, with the maximum operating distance reaching several hundred meters. The cost of a single obstacle removal is only one-fifth of that of traditional crane operations, significantly reducing operation and maintenance costs. Moreover, the laser wavelength does not cause damage to the line itself and can be safely applied to transmission lines of various voltage levels from 10kV to 500kV and railway catenary systems.
From the removal of foreign objects on power lines to the handling of hazards on railway catenary systems, and even assisting in obstacle removal in fire emergency scenarios, the HIZ-NT-QZY, with its characteristics of safety, efficiency, precision, and portability, has completely revolutionized traditional obstacle removal methods. It is not only an "infrastructure" for enhancing power supply reliability and ensuring line safety but also promotes the advancement of power operation and maintenance towards intelligence and unmanned operation, building a solid safety line for energy transmission and transportation operations.
