Foreign matter removal apparatus for overload power transmission line

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 technical field of electric power, and in particular relates to a foreign object removal device for an overhead power transmission line. Background technique [0002] The transmission line is an important part used for power transmission from the power station to the user unit. Whether it is in the city or in the wild, many transmission lines will be erected for power transmission. Then, in daily work, there will be many foreign objects on the transmission line, such as bird droppings , muddy water and other dirt, as well as hanging objects such as balloons, kites, and plastic bags. If these foreign objects are not disposed of in time, it is easy to cause a short circuit, which may cause line trips and power outages, 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 staff can use an insulating rod with a k...

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
