Description

Technical Field

[0001] The utility model relates to the field of towed cable array seabed acoustic detection and monitoring sonar, in particular to a small bending radius tow head connector structure for a towed linear array. Background Art

[0002] Towed linear array sonar is also called "towed array sonar". It is a sonar that detects targets in the water behind the stern of a ship by embedding hydrophones on cables to form a linear array. It is mainly used to listen to submarine radiation noise, conduct long-range monitoring, direction finding and identification, and some can also be used for distance measurement. It consists of a linear array, a towing cable, a retracting device, a winch, an electronic cabinet, etc.

[0003] At present, the towing cable and the linear array are connected by traditional towing head connectors. Because traditional towing head connectors need to integrate functions such as photoelectric transmission load-bearing and watertight sealing, the fixed part of the designed one-piece structure is relatively long, and the aspect ratio of its length to the outer diameter is generally not less than 3 times. As a result, after the towing linear array is wound on a winch with a small outer diameter, the towing head connector has a large protrusion on the winch. The towing linear array will have a large axial tension during the release process, which will cause greater stress damage to the protruding part of the towing head connector. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the above technical defects and provide a small bending radius tug connector structure for a towing line array that can effectively reduce stress damage and solve the technical problem of the tug connector part of the towing line array being able to withstand a small bending radius when coiled on a winch with a small bending radius.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is: a small bending radius tow head connector structure for a towed linear array, including a tow cable, the end of the tow cable is connected to a tow cable load-bearing device, and a tow linear array inter-segment connector socket is connected to the free end of the tow cable load-bearing device, the tow cable load-bearing device includes a head end connected to the tow cable and a tail end connected to the tow linear array inter-segment connector socket, a load-bearing structure is provided between the head end and the tail end, and the head end and the tail end are located in the load-bearing structure and are connected with photoelectric core wires.

[0006] As an improvement, the load-bearing structure includes a load-bearing rope and a PU tube connected between the head end and the tail end, and the PU tube is filled with polyurethane gel.

[0007] As an improvement, both ends of the PU tube are connected to the head end and the tail end respectively through buckling rings, and the load-bearing rope is an aramid load-bearing rope.

[0008] As an improvement, the tail end is a dragging linear array inter-segment connector plug that matches the dragging linear array inter-segment connector socket.

[0009] Compared with the prior art, the utility model has the following advantages: the load-bearing part and the photoelectric transmission part of the towing head connector are made into a split type, and are encapsulated in the middle by aramid ropes and PU tubes, etc., so that the aspect ratio of the fixed part of the towing head connector is reduced to less than 2 times, solving the problem of small bending radius of the towing line array towing head connector, so that the towing line array can smoothly transition when coiled on a winch with a small outer diameter.

The aramid ropes can be selected to be 2, 3 or 4 in number according to the actual working tension. The more ropes there are, the higher the tensile strength of the entire towing connector.
