AI Technical Summary

Problems solved by technology

The characteristics of this type of detection are: there is water between the detected surface and the detection device (camera or diver's eyes), if the water is clear, the image of the detected surface in the water can be obtained more clearly, and the detected surface cannot be effectively obtained if the water is turbid However, some defect information on the surface to be detected can only be revealed in a dry environment. For example, some defects on the surface of a ship’s hull can only be clearly revealed after docking, but cannot be detected in water

Abstract

The invention relates to a submarine investigation domain, especially relates to a movable submarine dry-state imaging device which can realize the submarine visual investigation, comprising a mini imaging module, an air inlet unit, a movable water insulation cover, wherein the air inlet unit is connected with the water insulation cover by air duct and a gasket is mounted at the opening of the water insulation cover and the mini imaging module is installed in the water insulation cover. The said device is convenient to carry and can obtain image of high quality with low cost and ensure the quality and speed of visual investigation and be suitable for various water areas such as turbid water.

Description

technical field [0001] The invention relates to the field of underwater detection, in particular to a movable underwater dry-state camera device capable of realizing underwater visual detection. Background technique [0002] The underwater state detection and evaluation of ships and other marine engineering structures is the premise to ensure their safety and realize condition-based maintenance, mainly including underwater visual inspection, thickness measurement, flaw detection, and measurement of protection potential. Among them, underwater visual inspection is mainly to obtain the image information indicated by the inspection, which is the most widely used technology in underwater inspection. [0003] At present, my country's underwater visual detection is based on underwater wet state detection, that is, through underwater observation by divers or through underwater cameras to obtain images of the surface to be detected. The characteristics of this type of detection are...
