technical field

The utility model belongs to the field of line inspection robots, in particular to a line inspection robot for omnidirectional monitoring of power lines.

Background technique

At present, line inspection robots are increasingly used in the field of power inspection, replacing manual monitoring and maintenance of power lines. During the power inspection process, when faults such as insulator flashover and local short circuit occur on the power line, the most direct manifestation is that the local temperature is too high. In addition, there are faults such as broken strands and accessories falling off in the power line. Therefore, power line patrol monitoring is a very critical link.

The monitoring of power lines usually adopts the following two methods:

(1) On-line monitoring: Install the monitoring device directly on the line or tower, monitor and collect the temperature and image signals of the line or accessories in real time, and transmit the data to the monitoring host, and upload it to the monitoring center through the communication module. This method can realize real-time monitoring of key parts of the power line, but due to the large scale of the power line, the monitoring range of this method is limited, and the implementation cost is high.

(2) Patrolling and monitoring: monitoring of power lines by human or robot. In this way, the monitoring range is relatively large, and the lines and accessories within the inspection range can be monitored more comprehensively. However, in this patrol monitoring mode, the monitoring equipment is usually fixedly installed on the line patrol robot. This installation method keeps the line patrol robot in a stable monitoring posture, and is usually more in line with human observation habits. However, this installation method also has a defect: the actual environment of the power line is usually more complicated, and it is inevitable that various power equipment will block each other, which will affect the accuracy of monitoring or miss some monitoring points.
