Solid towed sonar linear array and assembling method thereof

Abstract

The invention discloses a solid towed sonar linear array and an assembling method thereof. The solid towed sonar linear array comprises a plug core, a PU pipe, a solid filling glue, a main optical cable, a hollow framework, a device framework, a probe sealing chamber and a probe, wherein two ends of the PU pipe and the plug core are buckled and sealed to form a sealing chamber, the hollow framework and the device framework are arranged at equal distances and are mechanically fixed through a Kevlar rope, two ends of the Kevlar rope are fixedly connected with the plug core to form an internal force bearing structure, the probe is sealed in the probe sealing chamber, the sealing chamber is prepared through employing a transparent material, only the fiber is left for signal transmission, the main optical cable is arranged at an outer side of the framework, a certain margin is kept between the adjacent frameworks, the main optical cable is prevented from directly bearing force, the PU pipe is internally filled with liquid glue through a filling hole of an end surface of the plug core, after glue filling is ended, the filling hole of the plug core is sealed, after curing of the glue, the solid array is formed. The towed sonar linear array is composed of multiple solid arrays.

Description

technical field [0001] The invention relates to a sonar line array, in particular to a solid-state towed sonar line array. The invention also relates to an assembly method of the solid-state towed sonar line array. Background technique [0002] As a new generation of marine target detection equipment, the all-optical towed sonar system has the advantages of high sound pressure sensitivity and large dynamic range, and will gradually replace the traditional piezoelectric sonar system as the main marine detection equipment for ships and submarines. The towed sonar line arrays that have been developed at home and abroad are all filled with liquid, which has problems such as large flow noise, low reliability of the array, and pollution to the marine environment once the array is damaged. Contents of the invention [0003] The first technical problem to be solved by the present invention is to provide a solid-state towed sonar line array with low flow noise, high array reliabil...
