An auv multi-beam sonar carrying device

Abstract

The invention discloses an AUV multi-beam sonar carrying device. The AUV multi-beam sonar carrying device mainly comprises an AUV shell, a first electronics bay upper bearing part, a multi-beam electronics bay, a second electronics bay lower bearing part, a bearing bottom plate and a multi-beam right array; the bearing bottom plate is fixedly connected to the inner wall of the multi-beam AUV shell, and the upper surface of the bearing bottom plate is connected with the second electronics bay lower bearing part through first bolts; the first electronics bay upper bearing part is connected with the second electronics bay lower bearing part through second bolts; the annular inner wall of the second electronics bay lower bearing part is tangent with the circumferential outer surface of the multi-beam electronics bay; four parallel rectangular grooves are formed in the annular portion of the first electronics bay upper bearing part; chutes are formed in the two side walls of the AUV shell correspondingly, a multi-beam left array and the multi-beam right array are placed in the chutes correspondingly; four circular holes are formed in each of the two sides of the periphery of the chute of the left wall of the AUV, four circular holes are formed in each of the two sides of the periphery of the chute of the right wall of an AUV, and fixation is conducted through the holes; and an included angle between the multi-beam left array and the multi-beam right array is 60 degrees so that the good phase coherence can be maintained.

Description

technical field [0001] The invention relates to a multi-beam sonar carrying device for AUV detection, in particular to an AUV multi-beam sonar carrying device in which a multi-beam sonar array and an electronic cabin are separated. Background technique [0002] With the increasing demand of human beings for developing and using the ocean and the development of multi-beam technology, the use of multi-beam sonar for seabed topographic mapping has been extensively studied. However, due to the acoustic characteristics of multi-beam sonar, that is, the accuracy of surveying and mapping is related to the height of sonar from the bottom, the use of AUVs equipped with multi-beam sonar for near-bottom surveying and mapping has become an important and feasible means for deep seabed surveying and mapping. [0003] At present, there is no relevant design for the AUV multi-beam sonar carrying device. The more similar ones are: [0004] The publication date is September 16, 2015, the pub...
