Three-arm inspection robot for overhead line

Abstract

The invention discloses a three-arm inspection robot for an overhead line. The three-arm inspection robot comprises a case, a sensor and a three-arm inspection assembly, wherein the sensor is mounted on the case and is used for identifying a target and an obstacle, the three-arm inspection assembly is mounted above the case, each arm is provided with a tail end execution assembly, and each tail end execution assembly comprises a walking wheel driven by a motor to turn over and a pressing wheel driven by the motor to turn over. According to the three-arm inspection robot for a power transmission line, the combination mode that the three linear arms are matched with a horizontal module is adopted, the tail end execution assemblies are matched, and the robot case, the sensor and the like are carried. According to the three-arm line patrol robot for the overhead line, obstacle crossing can be directly achieved without transforming a shockproof hammer and a suspension clamp, meanwhile, the turning and climbing capacity is high, the structure is simple, and the robot can be charged autonomously and run on the power transmission line for a long time.

Description

technical field [0001] The invention relates to the field of inspection robots, in particular to a three-arm inspection robot for overhead lines. Background technique [0002] Electricity plays an increasingly important role in people's daily life and work. Ensuring the stable and normal operation of power equipment and the safe operation of the entire power system is the core issue in power management. The total mileage of my country's transmission lines has reached 1.59 million kilometers. The inspection and maintenance of these lines has become a major problem for the power grid. Electrical flashover, mechanical tension, material aging and other reasons may cause strand breakage, cracking, corrosion and other damages. If not repaired in time, it will seriously affect the normal operation of power, and even cause serious power outages and personal safety hazards. Therefore, in order to ensure the safe operation of the transmission line, it is necessary to conduct regular ...

Problems solved by technology

For example, the Shenyang Institute of Automation of the Chinese Academy of Sciences has developed a variety of inspection robots from 2005 to 2011, which can achieve climbing over anti-vibration hammers, wire clamps, spanning tension towers and strong climbing capabilities, but there are also complex structures. The problem of heavy weight and inconvenient operation

[0005] In order to solve the problem that existing transmission line inspection methods such as manual inspection, helicopter inspection, and UAV inspection are greatly affected by geographical environment and weather, the inspection time is short, the environment is dangerous, and the efficiency is low. At the same time, the existing transmission line inspection The degree of freedom of the robot is low, and it is necessary to modify the anti-vibration hammer, suspension clamp and tension clamp to operate, the ability to turn and climb is poor, the structure is complex and heavy, the protection level is low, and the life is low. It is necessary to provide a three-arm inspection robot for transmission lines. and line inspection method
