Watertight connector for underwater towed sonar

Abstract

The invention relates to a watertight connector for underwater towed sonar, which includes a watertight connector box, plugs that are sealed and assembled at both ends of the watertight connector box, and a connector that is sealed and assembled with a watertight connector cover on the watertight connector box. The watertight connector box, the plug and the watertight connector cover form a sealed space, and a storage protection box is arranged in the sealed space. The size of the watertight connector of the invention is smaller than or equal to the outer diameter of the detection array, which can reduce dragging noise. At the same time, it is made of lightweight, high-strength, corrosion-resistant aluminum alloy or titanium alloy, which is conducive to the control of "zero buoyancy" of the array. The inner sealing space of the connector of the present invention can accommodate redundant cables, and the cables are stored in a storage box made of flexible materials, which is beneficial to the protection of cables; and all connections are sealed with multiple layers, so the sealing is reliable. The connector of the invention is resistant to seawater corrosion, reliable in sealing, light in weight and capable of withstanding external forces in the sonar working environment.

Description

Technical field [0001] The invention relates to a connecting device, in particular to a watertight connector for underwater towed sonar used for connecting a detection array. Background technique [0002] The underwater towed sonar is composed of a multi-segment detection array. The detection array is the "ear" of the sonar system, with a total length of several kilometers, which is often formed by connecting the detection array section by section. As the connecting device between the detection arrays, the watertight connector needs to meet the characteristics of transmitting signals between the detection arrays, resisting water pressure, reliable sealing, and seawater corrosion resistance. At the same time, it also has sufficient mechanical properties to meet the forces between the detection arrays. The transmission and use of anti-external side pressure on the ship. Because the underwater towed sonar is mostly suspended in the water, the overall density of the array is require...

AI Technical Summary

Problems solved by technology

[0003] Traditional watertight connectors are mostly sealed in the form of flange butt joints, which are large in size and heavy in weight, and are mostly sealed with a single-layer sealing ring or the outer layer is vulcanized, which is easily affected by external forces and cause seal failure

Not only that, because the traditional watertight connectors are not designed to protect the cables, it is easy to cause damage to the cables, especially the optical fiber cables.
