Recently, in the cable trench of the substation of the newly rebuilt Science Park in Nanshan, a “big-eyed girl†with a height of less than 25 cm and a silver body was constantly turning the “small head†to look around and inspecting the equipment in the ditch. The looks "Meng Meng da" and "new", is the Nanshan Bureau developed to escape inspection "artifacts" - intelligent inspection robot cable channel. On the first day of "on-the-job", it sneaked into the narrow cable trench smoothly, and the colleagues in the distribution operation and maintenance class took full charge of the day's acceptance task.
Ground control underground
"The most fear is to drill the cable trench, which is black and smelly, and the space is small. Especially in summer, the temperature in the ditch is as high as 50 degrees Celsius, which is a great test for our physical strength and endurance." The experience, Xiaojiang of the Nanshan Bureau operation and maintenance class called "drunk." No, the reporter stood a few meters away from the mouth of the ditch and could smell a pungent smell.
"Now there is a robot, and the drilling of the ditch is not a problem at all!" Zhang Jinping, the squad leader of the Nanshan Bureau of Operation and Maintenance, demonstrated the robot's housekeeping skills to the reporter while remotely operating. I saw the robotic "head" searchlight that looks like a small tank, and the "foot" eight-wheel crawler. It walks flexibly under the direction of the ground controller , and sometimes moves forward, sometimes backs, sometimes turns, "big eyes" The camera is free to move up and down, and 360 degrees look around to detect the condition inside the ditch. At the same time, the HD video of the robot "eyes" and the environmental parameters of the cable ditch "temperature 24 ° C, humidity 38%" are all on the monitor.
According to reports, the robot adopts all-aluminum alloy body, which has high protection level and can adapt to various harsh environments of underground cable trenches. The track travel system has good obstacle walking ability, can exceed obstacles of more than 8 cm, and can Detecting the tilting state of the car body, whether it is climbing or cratering, it can be unimpeded; the camera is "sensory" sensitive, with 10x optical auto zoom, the staff can all the details in the cable trench through the monitor on the ground Real-time “scanning†for image recording, analysis and evaluation.
Emergency test robot advance
"In the past, cable trench inspections, at least 4 people were moved. They also had to carry a large number of tools such as infrared thermometers, toxic gas detectors, flashlights and cameras. Now only 2 people are needed, and other jobs are for robots. Contracting!†Zhang Jinping told reporters that in addition to daily inspections, the robot can also carry out inspection and supervision work for new cable trenches and new laying cable projects, and check the installation and tidy conditions of the trenches in the trenches. “It is not only time-saving but also time-consuming for robots. It is labor-saving, more efficient, and stricter, and the quality of work is higher."
"At the critical moment, the robot can't drop the chain!" Zhang Jinping said that once an emergency occurs in the cable trench, such as a fire, smoke or an unexplained power outage, the robot will act as an emergency "pioneer" and first enter the ditch test. Upload important information such as images, temperature and humidity, possible toxic and flammable hazardous gas contents in the accident area to the console for preliminary “diagnosis†to facilitate the next emergency repair work and avoid unnecessary personal injury.
At present, as a "new employee", the cable trench intelligent inspection robot is still in the "trial period", once "turned positive", "the future" will be bright. "We have just added the cable QR code information identification integration function, combined with the continuous improvement of the cable trench basic file and the underground pipeline verification work organized by the Shenzhen Municipal Planning and Land Commission, the cable and cable trench control will be further refined and intelligent. Niu Wennan, deputy director of the Nanshan Bureau, said that the bureau is deepening the functional application of this robot, encouraging employees to combine daily work, boldly carrying out innovative design and solving practical problems. "In the future, high-altitude inspection lines will be handed over to drones , cable trenches." Please check the robot for inspection!"
