MYUAV Dual-Tethered High-Altitude Cleaning Drone Supports Nanjing's First High-Speed Noise Barrier High-Altitude Cleaning Test

  Recently, a special cleaning test drew attention at the north Xiangshan Tunnel entrance of the south approach ramp to the Qixia Mountain Yangtze River Bridge in Nanjing. The MYUAV Dual-Tethered High-Altitude Cleaning Drone successfully completed Nanjing's first drone cleaning operation for the noise barriers of a long-span river-crossing expressway bridge.
  The cleaning of noise barriers has long been plagued by low efficiency and high operational risks. Traditional manual cleaning requires traffic closure and high-altitude work, which is time-consuming and labor-intensive. During this test, the MYUAV Dual-Tethered High-Altitude Cleaning Drone acted as a "flying cleaner", achieving precise ascent and flexible hovering. Powered by an uninterrupted energy supply from the tethered power system, the drone maintained stable operation for extended hours and efficiently removed dust and stains with high-pressure water mist.

  Test data shows that under permissible weather conditions, a single drone can clean 3,000 to 5,000 square meters within 6–8 hours per day, boosting efficiency by 3 to 5 times compared with manual work. Meanwhile, the entire operation is controlled intelligently from the ground, completely eliminating the risk of falls from height.

  As the provider of the tethered power supply solution for this test, MYUAV’s dual-tethered system delivers continuous power output via a ground tethered base station, ensuring stable hovering of the drone in complex environments such as bridge and tunnel openings. The system is applicable to four major scenarios: high-altitude cleaning, emergency lighting, communication relay, and high-altitude fire fighting. Its successful application in expressway noise barrier cleaning once again verifies the practical value of dual-tethered drones in the maintenance of municipal infrastructure, paving a viable path for the automated maintenance of municipal transportation infrastructure via drone technology.
