Embodiment 1

[0041] The present invention is realized through the following technical solutions, as figure 1 As shown, a laser remote foreign matter removal instrument includes a laser 1, a beam splitter 2, and a target imaging module 3. The laser 1 is used to emit a laser beam 11 to the beam splitter 2, and the beam splitter 2 transmits the received laser beam 11 After that, it is emitted to the target foreign object, and the target light 12 reflected by the target foreign object is visible light. The target light 12 is reflected by the beam splitter 2 and enters the target imaging module 3 to form a target image in the target imaging module 3 .

[0042] The present invention emits the laser beam 11 generated by the laser 1 on the target foreign matter, forms a high-power-density laser spot on the target foreign matter, and realizes the removal of the target foreign matter by means of melting or burning. The laser beam 11 generated by the cleaning device is usually invisible to the human ...

Embodiment 2

[0047] This embodiment is further optimized on the basis of the above-mentioned embodiment 1, such as figure 2 As shown, the collimating and focusing module 4 is arranged on the side of the beam splitter 2 close to the laser 1, and the laser 1 and the collimating and focusing module 4 are connected by an optical fiber 5, and the optical fiber 5 transmits the laser beam 11 generated by the laser 1 to the collimating and adjusting module The focus module 4, the collimating and focusing module 4 optically transforms the laser beam 11 input by the optical fiber 5 and outputs it as a collimated laser beam 13, or adjusts the collimating and focusing module 4 manually or automatically as required to output a certain A collimated laser beam 13 at a focal length. The collimated laser beam 13 passes through the beam splitter 2 and shoots to the target foreign object, and the target light 12 reflected from the target foreign object is reversely transmitted to the beam splitter 2 along t...

Embodiment 3

[0050] This embodiment is further optimized on the basis of the above-mentioned embodiment 1, such as image 3 As shown, a mirror 6 is added between the beam splitter 2 and the target imaging module 3, and the target imaging module 3 is arranged in parallel with the collimation and focusing module 4, and the target light 12 reflected from the beam splitter 2 passes through the mirror After the reflection of 6, enter the target imaging module 3 again. In this embodiment, since the target imaging module 3 is placed in parallel with the collimating and focusing module 4, the distance of the clearing instrument in the direction perpendicular to the optical axis of the emitted laser beam 11 is reduced. size. Adjust the setting position and angle of the beam splitter 2 and the reflector 6 according to the actual usage, so that the target light 12 from the target foreign object can enter the target imaging module 3 after being reflected by the beam splitter 2 and the reflector 6, and...

Abstract

The invention relates to a laser remote foreign matter removing instrument and a using method thereof. The laser remote foreign matter removing instrument comprises a laser, a spectroscope and a target imaging module, a laser beam generated by the laser is emitted to a target foreign matter to form a laser spot with high power density on the target foreign matter, and the target foreign matter isremoved by melting or burning. A laser beam generated by the removing instrument is usually invisible to human eyes. Therefore, the removing instrument needs to emit the laser beam, and needs to imagethe target foreign matter, so that before the laser beam removes the foreign matter, the hitting position of the laser beam can be determined by observing the target image, the position of the targetforeign matter needing to be hit coincides with the position of the aiming point, and then the foreign matter is removed. According to the invention, non-contact, long-distance and high-efficiency removal of the target foreign matter is realized by adopting the laser beam; and meanwhile, the removing instrument also has the characteristics of simple structure, small size, light weight and convenience in field carrying and use.

Description

technical field [0001] The invention relates to the technical field of laser foreign matter removal, in particular to a laser remote foreign matter removal instrument and a method for using the same. Background technique [0002] Foreign objects such as kites, plastics, and cloth pieces hanging or entangled on exposed high-voltage transmission lines, as well as foreign objects such as tree branches under or next to the transmission lines, may cause short circuits on the transmission lines, causing human and animal casualties, fires, power outages and other accidents. Contents of the invention [0003] The purpose of the present invention is to improve the deficiencies existing in the prior art, provide a laser remote foreign object removal device and its use method, and realize non-contact, long-distance and high-efficiency removal of target foreign objects. [0004] In order to achieve the purpose of the above invention, the embodiments of the present invention provide th...
