Embodiment
[0027] Embodiment: As shown in the accompanying drawings, the drag head of this underwater towing system mainly includes armored towing cable 1, shell 2, bushing 3, epoxy 4, sheath 12 of armored towing cable 1 and armored steel wire 11 sets of bushings 3, armored tow cable 1 outer shell 2, epoxy 4 is filled between the shell 2 and armored tow cable 1.
[0028] The armored tow cable 1 is armored steel wire 11, sheath 12, and wire 13 from outside to inside.
[0029] The bushing 3 is pressed into the armored steel wire 11 through the hydraulic working equipment 7 and the ejector rod 5, and the tail support clamp 6 fixes the armored tow cable 1 when pressed in.
[0030] The tail supporting fixture 6 is composed of an upper splint 61 and a lower splint 62 .
[0031] The hydraulic working equipment 7 is composed of a hydraulic pump 71 , a relief valve 72 , a reversing valve 73 and a hydraulic cylinder 74 connected to each other.
[0032] The assembly method of the drag head of the...

The invention discloses a towing head for underwater towed systems and a method for assembling the towing head. The towing head mainly comprises an armor towing cable, a shell, a lining, epoxide, an ejector rod, a tail support fixture and hydraulic work equipment. The lining is nested between a sheath and armor steel wires of the armor towing cable, the shell sleeves the armor towing cable, and spaces between the shell and the armor towing cable are filled with the epoxide. The lining is compressed in the armor steel wires under the matching effects of the hydraulic work equipment and the ejector rod, and the armor towing cable is fixed by the aid of the tail support fixture when the lining is compressed into the armor steel wires. The towing head and the method have the advantages that the towing head can be used for force bearing elements of the underwater towed systems such as sonar systems and marine acoustic measuring instruments, the maximum design breaking load of the towing head can reach at least 85% of the strength of towing cable bodies according to the method, and accordingly design requirements on the towing head can be met; repeated offshore verification and experimental verification are already carried out on the towing head, technologies are mature, and the towing head is already mounted in columns on multi-bow naval ships.
Description
technical field [0001] The invention relates to the field of underwater towing systems, in particular to an underwater towing system drag head and an assembly method. Background technique [0002] As an important branch of sonar, towed sonar can detect underwater targets at different depths by controlling the length of the towline and adjusting the depth of entry into the water. This kind of sonar has the advantages of being far away from platform noise interference and having a long working distance. Based on these characteristics, its use has attracted much attention in the industry. As an important part of it, the towline is the only channel connected to the mother ship, and it plays the dual task of carrying loads and transmitting signals. With the expansion of the towing system, it brings challenges to the safe use of the towline. [0003] The main components of the tow cable are: load-bearing part, waterproof insulation layer, and electrical transmission part. Among...
