A foreign matter removal device for overhead transmission lines

Abstract

The invention relates to a foreign matter removal apparatus for an overload power transmission line, and belongs to the technical field of electric power. The apparatus comprises a supporting frame and a group of cleaning cylinders hinged on the periphery; each cleaning cylinder adopts a two-petal type split structure, and at least two groups of walking mechanisms are arranged in the cleaning cylinders in the direction of the power transmission line; each walking mechanism comprises a pair of walking wheels arranged symmetrically up and down and a first motor; a cleaning mechanism is also arranged in each cleaning cylinder; each cleaning mechanism comprises four brush rollers and a second motor; each brush roller comprises a shaft roller and bristles on the surface thereof; a mounting ringwith an L-shaped cross section is arranged at one end of each cleaning cylinder, and a two-petal-structured graphite ring is arranged in the lower concave position; a cutting mechanism is arranged onthe periphery of the graphite ring; and the cutting mechanism comprises a rotating ring with a driving mechanism and a group of cutters annularly arranged on the outer side. By virtue of the foreignmatter removal apparatus, cutting, drilling and stripping of suspending and covering objects and cleaning of relatively small foreign matters can be realized; and the foreign matter removal effect canbe remarkably improved, and foreign matter removal from the power transmission line can be truly realized.

Description

Technical field [0001] The invention belongs to the field of electric power technology, and in particular relates to a foreign matter removal device for overhead power transmission lines. Background technique [0002] Transmission lines are important components used for power stations to transmit power to subscriber units. Many transmission lines are set up to transmit power, whether in cities or in the wild. Then, in daily work, there will be many foreign objects on the transmission lines, such as bird droppings. , Muddy water and other pollutants, as well as hanging objects such as balloons, kites, and plastic bags. If these foreign objects are not treated in time, they will easily cause short circuits, which may cause line trips and power failures, causing unnecessary losses to people's lives and production. . [0003] At present, there are three traditional methods for removing foreign objects in the line: 1) The worker can use an insulating rod with a knife to stand on the gr...

Problems solved by technology

The first method, due to the limited length of the operating rod, may encounter places that cannot be cleaned during the operation, and this method is limited by the terrain; the second method requires a lot of manpower and material resources, and the operation procedures are complicated and dangerous. There are many points, and the targeted safety measures are cumbersome, which can easily lead to electric shock accidents due to mental paralysis, and the labor intensity is high and the reliability is low; the third method needs to be contacted and coordinated with the control center in advance to formulate a power outage plan and perform approval This kind of operation process makes it impossible to deal with defects in time, and the power outage operation greatly reduces the power load, affects the power supply reliability of the transmission line, and reduces the transmission efficiency
