Description

Technical Field

[0001] The invention relates to a cable inspection device, which is specifically used for cable inspection in narrow spaces such as cable corridors. Background Art

[0002] With the development of society, compared with overhead lines, power cable channels account for an increasingly higher proportion of power transmission lines due to their advantages of less space, high reliability, and less maintenance workload. The inspection and maintenance of power cable channels are particularly important for the safe operation of power cables and are of great significance for ensuring the safe operation of power systems. Due to different considerations in different periods, the standards for the construction of power cable channels are also different. First, the space of some old cable corridors is small, the cable laying is crowded and chaotic, and the workers are at risk of electric shock; second, the ladders of some old cable corridors are rusted and corroded, and the workers are at risk of falling from heights; third, the construction of some working wells does not meet the current standards, there are no ladders, and the workers need to move insulating ladders up and down, which seriously affects work efficiency; third, the cable channels are relatively humid in summer, harmful gases increase, and the risk of toxic gas injury to workers increases.

[0003] There are two main methods for patrolling power cable channels: one is manual patrol, that is, staff carry patrol equipment to patrol; the other is a complete set of patrol equipment, that is, set up a special track in the power cable channel, install patrol equipment on the track, and realize unmanned patrol of specific channels.

[0004] Commonly used inspection equipment for manual inspections include infrared imagers and digital cameras. Both devices are directly handheld and cannot be placed in the power cable working shaft with only the human arm's distance. Inspection personnel must enter the power cable working shaft to conduct power cable channel inspections.

[0005] The complete set of inspection equipment has the following problems: first, the investment cost is high, and special tracks and inspection devices need to be installed; second, the flexibility is poor, and it can only be used in the power cable channel where the equipment is installed; third, the scope of application is small, and it is difficult to install the complete set of inspection equipment in old power cable channels. Therefore, the current power cable channel inspection technology is still mainly based on manual inspection. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide an insulated cable corridor inspection pole in view of the above-mentioned deficiencies in the prior art, which enables inspection personnel to inspect the power cable corridor without having to enter the power cable corridor, thereby reducing the frequency of workers entering the work pit, ensuring the personal safety of workers, and improving the work efficiency of workers.
