Intelligent walking mechanism for inspecting operating condition of high-voltage line

Abstract

The invention discloses an intelligent walking mechanism for inspecting the operating condition of a high-voltage line, and the mechanism provided by the invention comprises a walking arm I, a walking arm II, a guide rail and a box body component, wherein the walking arm I and the walking arm II respectively comprise a rotating component, a lifting component and a walking component and can walk on an optical fiber composite overhead ground wire; the walking mechanism can be used as a carrier of inspection equipment and can be used for overcoming the defects of low manual line walking accuracy, low efficiency, high labor intensity, blind area and the like; the two walking arms of the walking mechanism can retract and rotate and are supported by dual wheels; the center of gravity of the walking arms can be adjusted through box body sliding; and while crossing a tower, one of the walking arms is used as a support, the other walking arm lifts and rotates to avoid obstacles and cross the obstacles by means of single-arm walking, so that the obstacle crossing capability is strong. Meanwhile, the walking mechanism has simple and reasonable structure, light weight and strong endurance capability, is convenient to carry and has great significance for ensuring safe operation of the power transmission line and the communication line.

Description

technical field [0001] The invention relates to a damage detection device for a high-voltage transmission line, in particular to a walking mechanism for walking on a grid-hanging operation line for video inspection. Background technique [0002] In recent years, with the construction of the high-voltage line backbone network, more and more high-voltage transmission lines are running on the grid, and at the same time, operational defects are gradually exposed, such as: the outer strands of the high-frequency OPGW optical fiber composite overhead ground wire are broken , this outer layer of broken strands not only poses a threat to communication security, but also poses a serious threat to the safety of transmission lines as the length of the loose strands increases and the mechanical strength of the line decreases. According to the survey and statistics on the broken strands of the transmission line, the broken strands are generally broken strands of the outer monofilament. T...

Problems solved by technology

[0003] At present, the commonly used inspection method is the manual inspection method. This method has a large workload, difficult conditions, and low inspection accuracy. Inspection items are difficult to complete by conventional methods

In order to achieve the purpose of comprehensive inspection, the inspection method of helicopter aerial survey has appeared, which has high accuracy and efficiency, but due to the influence of geographical and climate conditions in the inspection area, there are potential safety hazards, and the inspection cost is high

In addition, inspection equipment that walks directly on the transmission line for detection has also appeared, but there are generally shortcomings such as weak obstacle-crossing ability and poor battery life.
