High-voltage line deicing robot

Abstract

The invention provides a high-voltage line deicing robot and belongs to the field of mechanical engineering. The high-voltage line deicing robot is used for taking the place of manual working aloft, improving the working efficiency and reducing the rate of casualty accidents. A body structure of the robot is composed of five parts, namely a deicing tool, a traveling mechanism, an obstacle crossing mechanism, a drive system and an image pick-up unit. The deicing tool is composed of a deicing abrasion wheel and a deicing hammer, and is used for achieving the deicing in a cutting-knocking combined manner. The obstacle crossing mechanism is integrated with the traveling mechanism to realize the obstacle crossing function of the robot and also ensure that mechanisms travel on the line. The drive system is composed of three drive lines and can be used for transferring power in a gear engagement manner. The image pick-up unit is used for feeding back the working conditions of the robot in real time to the ground, and therefore, the accuracy and the reliability of working are guaranteed; a ground communication control system is capable of performing on-line fault diagnosis and remote control on the robot. The high-voltage line deicing robot is high in efficiency, safe, reliable, cheap and practical in compared with a traditional deicing manner.

Description

technical field [0001] The high-voltage transmission line deicing robot is a device used to replace manual deicing of high-voltage lines. It belongs to the field of mechanical engineering and realizes the maintenance of high-voltage lines. Background technique [0002] With the rapid development of my country's electric power industry, the coverage area of ​​high-voltage transmission network continues to expand, and the lines pass through different geographical environments. Some areas often encounter low temperature, ice, snow or freezing weather. However, since the atmospheric temperature is lower than zero and the air humidity is relatively high, the melted ice will quickly condense into ice, making the speed of freezing faster than the speed of melting, resulting in more and more ice. Severe icing of high-voltage lines will lead to collapse of towers, wire galloping, disconnection, insulator flashover and de-icing jumps, etc., causing accidents such as line tripping and p...

AI Technical Summary

Problems solved by technology

Mechanical deicing methods include strong vibration method and pulley scraping method. This method is cheap, but consumes a lot of manpower and material resources, and the deicing efficiency is low; thermal deicing mainly includes three-phase short-circuit deicing and load deicing. Compared with deicing, the deicing speed is faster and the safety is higher, but it can only be used for local lines

For severe wire icing, manual deicing is generally the most effective method, but manual deicing is very dangerous and the efficiency is low
