Connecting device used for carrying side-scan sonar and working method thereof

Abstract

The invention discloses a connecting device used for carrying a side-scan sonar and a working method thereof, belonging to the technical field of naval architecture and ocean engineering. The connecting device comprises a hanger rod mechanism and a rack mechanism. The hanger rod mechanism consists of a lifting point part, a cardan joint, a vertical pull rod, and the like. The rack mechanism consists of a Z-shaped cross beam, a torsion and bending resisting part, a vertical fastened side-scan sonar part, an axial limiting part, and the like. The side-scan sonar is fastened on the rack mechanism which is fixedly connected with the hanger rod mechanism through six mounting screw holes and bolts. The entire connecting device is ingenious in design, simple in structure, convenient to install and uninstall, high in strength and rigidity, light in weight, simple in maintenance and high in operating reliability. The connecting device can effectively resist the interferences from sea wind, wave and flowing loads, can not only be hung at a shoreside of a wharf but also be hung at a gunwale or a stern shrouding of a boat, and can move under traction along with the navigation of the boat. The connecting device can self-adaptively adjust the measurement angle of the side-scan sonar to keep the side-scan sonar stay at the optimum position and posture all the time so as to improve the detection precision and the measurement effect of the side-scan sonar.

Description

technical field [0001] The invention relates to a connection device for carrying a side-scanning sonar and a working method thereof, which can be used in projects such as shipbuilding, navigation and ocean detection, and belongs to the technical field of ships and ocean engineering. Background technique [0002] When the side-scan sonar works in water, it usually needs to be installed on some kind of support, and the side-scan sonar is carried by the movement of the support for detection work. The side scan sonar will be disturbed by environmental factors such as wind, waves and currents in the water, which will change the working attitude of the side scan sonar, thus affecting the detection accuracy and measurement effect of the side scan sonar. How to ensure that the side-scan sonar is at the best detection angle in water, and how to fix or adjust the working attitude of the side-scan sonar are key technical issues. [0003] At present, there is still a lack of mechan...

AI Technical Summary

Problems solved by technology

The problem with this connection method is that the constraints on the working attitude of the side-scan sonar are weak. Under the interference of the ocean environment, the position and attitude of the side-scan sonar will change randomly, so that the side-scan sonar cannot maintain the best detection angle in water, resulting in Detection accuracy and measurement effect distortion

Therefore, the existing method of connecting side-scan sonar cannot meet the requirements of actual engineering surveys. A new effective mounting device is needed to connect side-scan sonar to ensure that side-scan sonar can effectively resist interference from the sea environment. Side-scan The sonar can always maintain the best measurement working angle and position attitude, improving the detection accuracy of the side-scan sonar
