Camera lifting system for cable trench inspection robot

Abstract

The invention belongs to the technical field of cable inspection, and particularly relates to a camera lifting system for a cable trench inspection robot. The camera lifting system comprises a base and an imitation four-connecting-rod assembly, and a stroke block is arranged on the base; the bottom end of a first rocking bar of the imitation four-connecting-rod assembly extends downwards and is inhinged fit with the stroke block; the bottom end of the first connecting rod is fixedly connected to the position, behind the stroke block, of the end of the base, and the top end of the first connecting rod extends forwards and is in hinged fit with the bottom end of the supporting rod; a first sliding sleeve is hinged to the top end of the first rocking bar and is in sliding rail fit with the first connecting rod; the tail end of a second connecting rod is hinged to the middle section of a rod body of the first rocking bar, the top end of the second connecting rod is hinged to the bottom end of a second rocking bar, and a second sliding sleeve is hinged to the top end of the second rocking bar and is in sliding fit with the supporting rod; and the top of the supporting rod is fixedly connected with a camera assembly. The camera lifting system can provide a basic guarantee for the subsequent through-wall operation of a cable tunnel inspection robot.

Description

technical field [0001] The invention belongs to the technical field of cable inspection, and in particular relates to a camera lifting system for a cable trench inspection robot. Background technique [0002] The occurrence of fires in cable tunnels is a process of gradual accumulation. With the increase of time, due to the aging of the insulation layer, the accumulation of dust and oil, and the looseness of the intermediate joints, the local temperature of the cable will gradually rise, which will cause a fire. Before the accident occurs, if the temperature and smoke inside the cable tunnel can be effectively monitored in real time, the fire can be prevented before it happens. Although the monitoring problem of cable tunnel has attracted people's attention, but has not found a proper and reasonable solution. [0003] Traditional cable tunnels are manually inspected. At regular intervals, inspectors enter the tunnel and use temperature measuring instruments to manually ch...

However, the disadvantages of thermal wires are: firstly, the cables located on both sides of the cable tunnel are bundled and arranged in bundles, and the thermal wires can only monitor the high temperature changes of the adjacent cables that are close to each other, and the thermal wires located at the farthest end The temperature change monitoring effect of the cable is very poor

The existence of the firewall makes it necessary to repeatedly take out the tunnel inspection robot from the previous tunnel unit-reset the cover plate on the previous tunnel unit-remove the cover plate of the new tunnel unit-replace the tunnel inspection robot every time it inspects the tunnel inspection robot. The process of entering the tunnel inspection robot is extremely complicated and requires a lot of physical labor, which obviously seriously restricts the actual inspection efficiency.

On the other hand, as stated above, the cables in the cable tunnel are arranged in bundles, so there is a certain height. The traditional tunnel inspection robot can inspect the height constant, and there must be some dead ends of the cables that cannot be inspected, resulting in inspection loopholes. ,There are security risks
