In order to safely and efficiently remove the floating foreign matters on the 10 kV overhead distribution lines

different foreign matter treatment devices are compared and analyzed

and a device for removing floating foreign matters in the transmission line for unmanned aerial vehicle（UAV） is designed. The device includes UAV

connecting rod

insulating rod

cutting component

gripper component and screw hook assembly suitable for different floating objects

so as to realize the cutting

separation and grasping of floating objects.The actual application results show that the device is convenient and practical

with low labor intensity and high work efficiency. It can effectively remove floating foreign matters on the conductor in the live environment

and provide guarantee for the safe operation of 10 kV overhead distribution lines.
