Underwater detection device for turbid water area

Abstract

The invention discloses an underwater detection device for a turbid water area. The underwater detection device comprises a flexible wall-attaching module, an underwater device box, an optical image acquisition equipment module, an illumination module, a retractable cable device and a display control module, wherein the flexible wall-attaching module is connected with a front flange in the underwater device box through fastening bolts, and sealing is realized through an O-shaped sealing ring; the illumination module and a camera device are integrated and mounted on a rear cover of the underwater device box; signal wires of the illumination module and the camera device are led out, coiled on the retractable cable device and connected with the display control module, thereby being used for supplying power to the camera device and the illumination device and transmitting signals and data. A front flexible membrane is utilized for observing the underwater area with low visibility in a large range; high-definition image information is acquired by a high-definition camera and the luminance-adjustable illumination device. The device is simple to operate and convenient to carry, and desired high-definition video images of an invisible detection area can be obtained.

Description

technical field [0001] The invention relates to a detection device, in particular to an underwater detection device, which is applied in the technical field of underwater optical imaging equipment. Background technique [0002] For inland rivers and offshore waters with poor visibility and high sediment content, high-resolution optical imaging equipment cannot achieve good detection results. In such waters, various sonar detection equipment are used more. Sonar detection equipment can construct the outline map of the underwater object very well, but it cannot obtain some text information attached to the object, such as the patterns on the ceramics, the ship model printed on the sunken hull, and the water surface. Submerged mural motifs and more. In most inland waters in China, the water quality is basically turbid, and divers have zero visibility underwater. There are often countless cultural relics that have protection value but cannot be moved temporarily in some rivers...

AI Technical Summary

Problems solved by technology

These cultural relics can be searched with sonar equipment first. After the suspicious places are identified, because some objects cannot be salvaged, their protection value cannot be determined. For example, for huge objects that are difficult to salvage such as sunken ships, it is necessary to identify their models To determine whether it has protection value, if the sonar image analysis map of the ship is obtained, it is obviously very difficult to determine the type and protection value of the sunken ship only through the sonar image analysis map of the shipwreck, and it is not very convincing
