Deicing robot magnetic torque rotary driving device based on magnetically and electrically conductive material

Abstract

The invention discloses a deicing robot magnetic torque rotary driving device based on a magnetically and electrically conductive material. The device comprises a body magnetic core and an electrified wire. The body magnetic core is a quincunx magnetic core with a hollow center and an outer edge composed of multiple bosses. The body magnetic core is composed of an upper body magnetic core and a lower body magnetic core by using a high-voltage DC transmission wire as an axis, wherein the upper body magnetic core and the lower body magnetic core have same structure and can be opened and closed. The boss is composed of a first radial edge, a second radial edge and an outer ring edge. The adjacent bosses are connected by inner ring edges. The first radial edge and the second radial edge of each boss are provided with symmetric magnetically and electrically conductive sheet layers with the same number. The parts except the magnetically and electrically conductive sheet layers of the first radial edge and the second radial edge, the outer ring edge and the inner ring edge are all made of magnetically conductive insulating materials. The electrified wire is used for connecting the magnetically and electrically conductive sheet layers. The method can avoid magnetic flux leakage and the like caused by a guide hole, can increase the deicing speed of a deicing robot and has advantages of small size, light weight and low cost.

Description

technical field [0001] The invention belongs to the technical fields of material science and magnetic field, and in particular relates to a magnetic torque rotation driving device of a deicing robot based on a magnetically conductive and conductive material, which is used to drive the deicing device of the robot. Background technique [0002] Since the 1980s, robots for overhead high-voltage transmission lines have been a research hotspot in the field of robotics. The United States, Japan, Canada, China and other countries have successively carried out research work on overhead high-voltage transmission line operation robots. In 2008, Japan's Debenest et al. developed an inspection robot named "Expliner" for high-voltage multi-split conductors. In 2000, Montambault and others from the Quebec Hydropower Research Institute in Canada developed a remote control car called HQ Line-ROVer. The car was initially used to remove ice accumulation on the ground of power transmission li...
