Porcelain bottle crack detection device and method for 10kV and below power transmission lines

Abstract

The invention provides a porcelain bottle crack detection device for the 10kV and below power transmission lines. The device comprises a supporting rod, a foot stand arranged at the bottom of the supporting rod, a main control guide rail arranged in the middle of the supporting rod, an information acquisition module arranged at the top of the supporting rod and a main control module sliding in themain control guide rail. The information acquisition module comprises a camera unit, an acquisition wireless unit and a three-dimensional rotary holder, the camera unit further comprises a first camera and a second camera which are arranged side by side, and the first camera and the second camera synchronously rotate on the three-dimensional rotary holder and have the same image centers. The first camera is a long-focus black-and-white lens, and the second camera is a wide-angle color lens. According to the invention, by combining the supporting rod and the pan-tilt cameras, and selecting theproper observation points manually, the detection device automatically positions and recognizes the porcelain bottles, acquires the images of the porcelain bottles and detects the cracks of the porcelain bottles, so that the problems that the patrol inspection is difficult by using an unmanned aerial vehicle, and the ground observation angle is not good, are solved.

Description

technical field [0001] The invention relates to the technical field of automatic detection, in particular to a device and method for detecting cracks in porcelain vases of transmission lines of 10kV and below. Background technique [0002] Insulating porcelain bottles on 10kV and below transmission lines are generally isolated by a single unit, which are generally deployed vertically on the ground. In actual operation, it is found that the early cracks of porcelain bottles usually appear on the shed at the top, which is difficult to find on the ground. Faults such as broken or missing porcelain bottles will only be discovered, often causing power outages; since most of the transmission lines of 10kV and below are located in places with a large population, there are many crossing lines around, and there are obstacles such as buildings and trees. The inspection plan is not applicable, which makes it difficult to find such faults in the early stage, and power outages caused by ...

[0002] Insulating porcelain bottles on 10kV and below transmission lines are generally isolated by a single unit, which are generally deployed vertically on the ground. In actual operation, it is found that the early cracks of porcelain bottles usually appear on the shed at the top, which is difficult to find on the ground. Faults such as broken or missing porcelain bottles will only be discovered, often causing power outages; since most of the transmission lines of 10kV and below are located in places with a large population, there are many crossing lines around, and there are obstacles such as buildings and trees. The patrol inspection plan is not applicable, which makes it difficult to find such faults in the early stage, and power outages due to faults in insulating porcelain bottles occur from time to time

At present, the detection of this kind of insulating porcelain bottles is generally carried out by inspectors carrying telescopes and other equipment along the line. Due to poor observation angles, it is difficult to find cracks, and it mainly depends on the experience of inspectors to judge whether there are cracks.
