Problems solved by technology

[0003] Purpose: In order to overcome the deficiencies in the existing technology, the traditional tools and methods for removing foreign matter on the transmission line require high-altitude and high-voltage operations, difficult operations, high risks, low removal efficiency, and sometimes require power outage operations. The invention provides a fiber laser-based foreign object laser removal device for overhead lines, which can remotely and quickly remove foreign objects on all levels of overhead transmission lines, and can work remotely and live without high-altitude and high-voltage operations, and has high removal efficiency

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] like figure 1 As shown, it is a laser removal device for foreign matter in overhead lines based on a fiber laser, a fiber laser 1, a power supply 2, an optical fiber 3, a transmitting part 4, and a sight 5;

[0021] Power supply 2, as a preference, the power supply is a combination of a battery pack and an inverter, the battery provides DC power, and the inverter converts the DC power into the AC power required by the fiber laser;

[0022] The fiber laser 1 is connected to the power supply through the power cord, and connected to the transmitting part 4 through the optical fiber 3;

[0023] The emitting part 4 is fixed in parallel with the sight 5, and the optical axis of the internal optical path of the sight is parallel to the optical axis of the internal optical path of the emitting part, and is used for observing and aiming at remote foreign objects. Prefe...

Abstract

The invention discloses an optical fiber laser device-based laser removal device for a foreign matter on an overhead line. The laser removal device comprises an optical fiber laser device, a power supply, an optical fiber, a transmitting part and a sighting device, wherein the optical fiber laser device is provided with electricity by the power supply and is connected to the transmitting part through the optical fiber; emitted laser light is transmitted to the transmitting part through the optical fiber; the transmitting part is used for shaping a laser light beam into a quasi parallel light beam or a convergent light beam with a focal length for outputting; and the sighting device and the transmitting part are arranged in parallel and are used for remotely observing and sighting the foreign matter. The other auxiliary equipment is not needed, the risks of tower climbing, high-altitude operation and near-field operation under a high voltage condition of an operator are omitted, the operation is simple, the removal efficiency is high and a lot of manpower and material resources can be saved.

Description

technical field [0001] The invention relates to a fiber laser-based foreign matter laser removal device for overhead lines, which belongs to the technical field of power transmission and transformation equipment. Background technique [0002] At present, the vast majority of power transmission and distribution lines are erected in the air through poles and towers with bare metal wires without insulation protection. Floating foreign objects such as kites, kite lines, plastic cloth, and advertising cloth are easily entangled on the bare metal wires. This kind of floating foreign matter is soaked by rain, snow, and dew, which can easily cause faults such as short circuit between metal wires and single-phase grounding, which will cause tripping of power transmission and distribution lines, power failure or line damage, and foreign objects that hang down to places accessible to humans and animals , may cause human and animal casualties, therefore, timely cleaning of foreign objec...
