An automatic foreign matter removal device for transmission lines

Abstract

The invention relates to an automatic foreign object removing device for a power transmission line, and belongs to the technical field of electric power. The automatic foreign object removing device comprises a support frame and a group of cleaning cylinders hinged at the periphery of the support frame, and is characterized in that each cleaning cylinder is of a two-piece split structure, the internal part of the cleaning cylinder is provided with more than two groups of walking mechanisms along the direction of the power transmission line, and each walking mechanism comprises a pair of walking wheels which are symmetrical arranged up and down and a first motor; the internal part of the cleaning cylinder is further provided with a sweeping mechanism, the sweeping mechanism comprises four brush rollers and a second motor, each brush roller comprises a shaft roller and a brush at the surface of the shaft roller, one end of the cleaning cylinder is provided with a mounting ring with the cross section being L-shaped, a graphite ring of a two-piece structure is mounted at a recession of the mounting ring, a cutting mechanism is mounted at the periphery of the graphite ring, and the cutting mechanism comprises a rotating ring with a driving mechanism and a group of cutters which are arranged along the annular shape at the outer side of the rotating ring. The automatic foreign object removing device can realize cutting, drilling and stripping of suspended objects and covers and the cleaning of small foreign objects. The cleaning effect is significantly improved, and removal of foreign objects on the power transmission line can be truly achieved.

Description

technical field [0001] The invention belongs to the technical field of electric power, and in particular relates to an automatic foreign object removal device used on transmission lines. 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 kni...

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
