Abstract

The invention relates to a device and method for detecting the inside of a small-diameter high-pressure water filling pipeline. The device comprises an aircraft, a cable and a controller; a bow part of the aircraft is of a hemispherical expansion structure, a middle part of the aircraft is of a pressure-resistant cabin, and a tail part of the aircraft is of an ellipsoidal structure; a vertical propeller, horizontal propellers, cameras, lighting lamps, a main control panel and a cable connector are arranged in the aircraft; a signal output end of each camera is correspondingly connected with asignal input end of the main control panel; a signal output end of the main control panel is respectively connected with control signal input ends of the vertical propeller, the horizontal propellers,the cameras and the lighting lamps; the signal input end and the signal output end of the main control panel are connected with the cable connector; and the two ends of the cable are respectively connected with the cable connector and the controller. The method comprises the steps of initializing, acquiring real-time images, carrying out fault diagnosis and image capture, processing the images, carrying out feature extraction, deciding fault categories, storing and displaying results. The device and method for detecting the inside of the small-diameter high-pressure water filling pipeline have the advantages of compact structure, flexible motion, easy control and high identification.

Description

technical field [0001] The invention relates to internal detection of a water-filled pipeline, in particular to a detection device and a detection method for the interior of a small-diameter high-pressure water-filled pipeline. Background technique [0002] With the increasing demand for the development of underground and underwater resources, environmental protection of water resources, and marine military exploration, the inspection of the interior of water-filled pipelines has become an important daily work. Because of its strong environmental adaptability, wide range of activities, and ease of use, underwater vehicles are important tools for underwater research and the development of water-filled limited areas. Among them, micro underwater vehicles are small in size, low in cost and high in maneuverability, and are widely used in operations in limited local water environment such as deep water pipeline inspection. The inside of a high-pressure water-filled pipeline with...
