Cable trench status patrol robot

Abstract

The invention discloses a cable trench status patrol robot. The cable trench status patrol robot comprises at least three joints. The left side and the right side of each joint are each provided witha set of travelling mechanism. Every two adjacent joints are connected with a connection shaft and a steering engine, the steering engine is arranged on the later joint and hinged to the former jointthrough the connection shaft. A head joint and / or a tail joint are / is provided with a two-degree-of-freedom cradle head. The two-degree-of-freedom cradle head is provided with a high-definition cameraand an LED light. The angles of the high-definition camera and the LED light are adjusted through the two-degree-of-freedom cradle head, at least one intermediate joint is provided with a sensor assembly used for monitoring cable trench environment parameters, a power supply for providing power for the robot, and a controller used for controlling the LED light, the travelling mechanisms and the steering engines. The robot can automatically travel in narrow, small and complex cable trenches and climbs and crosses obstacles, and by means of the high-definition camera and various sensors, the cable trench actual operation status and operation environment are monitored overall.

Description

technical field [0001] The invention relates to electric power inspection technology, in particular to a cable trench inspection robot. Background technique [0002] The cable trench is an indispensable infrastructure of the power grid. The cable in the trench not only involves power transmission, but also involves equipment such as relay protection, automatic control, communication, measurement and metering. It is the nerve center of the power grid. Once a cable fails, not only inspection and processing It is difficult and takes a long time, and it may also cause the relay protection or control circuit to fail, causing the accident to expand or even damage the main equipment, and the production cannot be resumed for a long time. Therefore, it is of great significance to strengthen the status monitoring and management of cable trenches, discover hidden dangers of cables in time, and protect cables from damage, which is of great significance to the safe operation of power gri...

AI Technical Summary

Problems solved by technology

[0003] At present, there are many problems in the use of cable trenches, mainly as follows: First, there is a lack of online monitoring of the cable operating temperature, especially the temperature of the cable joints. Under high voltage and high current conditions, it is easy to cause temperature rise, damage the insulation layer, and eventually lead to fire

The second is the lack of on-line monitoring of harmful gases. Various garbage in cable trenches are easily catabolized by microorganisms to form combustible gases such as methane. The ignition point of methane is very low. The operation of the operation brings considerable hidden dangers

Third, there is a lack of monitoring of the water in the cable trench. During the rainy season, many cables are running under flood conditions, which seriously affects the cable insulation and service life.
