[0003] For example, Chinese utility model patent with publication number CN220177300U provides a pipe inner wall spraying device. This device uses a robot that can walk inside the pipe to pull an infusion tube and a nozzle to spray inside the pipe. A nozzle is mounted on the tail of the robot. When the robot walks, it is in the center of the pipe. The nozzle can evenly spray the anti-corrosion agent onto the inner wall of the pipe. Using a flexible tube as an infusion tube, the spraying amount can always be kept the same in a long pipe, so that the anti-corrosion agent is sprayed more evenly inside the pipe.
