Small-sized caterpillar belt inspect robot system for cable tunnel hazardous environment

Abstract

The invention relates to small-sized caterpillar type inspection robot system for dangerous cable tunnel environment, which comprises a movable platform, an upper cover, a gas sensor box, a data transmission antenna, an image transmission antenna, a thermal camera tripod head, an ultrasonic sensor, a wireless monitoring device, a control box, a control unit and an operation panel, wherein the movable platform comprises a front guide belt wheel, a locking bolt, a swinging arm, a first tension bolt, a front load-bearing wheel, a second tension screw, a middle guide wheel, a caterpillar, a rear load-bearing wheel, a worm speed reducer, a swinging arm motor and a driving motor. Compared with the prior art, the system overcomes the drawbacks of the prior cable tunnel inspection technology, avoids dangerous factors caused by manual inspection, simplifies the robot mechanism and provides a simple, high-efficiency and reliable mechanism for cable tunnel inspection.

Description

technical field [0001] The invention relates to the application field of robot technology, in particular to a small crawler inspection robot system in a dangerous environment of a cable tunnel. Background technique [0002] Since the 1980s, many domestic cities, large power plants and industrial and mining enterprises have successively adopted underground cable tunnels to supply electric energy. In order to ensure the safety of the operators entering the cable shaft tunnel, it is required to carry out various protection tests on the cable shaft tunnel and take regular and fixed-point inspection measures to avoid accidents. In addition to the fire prevention measures of the cable itself, the current protection measures generally install a fire alarm system and a gas fire extinguishing system in the cable tunnel, and conduct online temperature monitoring of the cable tunnel. For the network monitoring system, there are mainly the following deficiencies: [0003] 1 The cable ...

AI Technical Summary

Problems solved by technology

[0003] 1. The cable tunnel is several kilometers to more than ten kilometers long. In such a long passage with harsh environment, it is unrealistic to use a networked monitoring system with large investment and insignificant benefits.

[0004] 2 Cable fires smolder for a long time (generally 3 to 4 hours). Traditional fire detectors cannot detect fires during this period because of their low sensitivity and passive detection methods.

[0005] 3 There may be some harmful gases in the tunnel. The current network monitoring system generally only monitors the temperature, and cannot realize the comprehensive detection of temperature and gas, and cannot guarantee the safety of the gas inside the tunnel for the staff entering the tunnel.

[0006] 4 Unable to conduct post-disaster assessment

Although the above-mentioned crawler robots can perform certain risk-removal inspection operations, their weight and size do not meet the specific application of underground tunnel inspection.
