Description

Technical Field

[0001] This invention belongs to the field of watertight cables, and more specifically, relates to a tensile and pressure-resistant watertight armored branch cable. Technical Background

[0002] Towing cables are key connectors for most underwater towing equipment, used to enable signal connections between the equipment and the surrounding environment and for underwater signal transmission. They are an essential component of underwater towing equipment. For non-uniform cable underwater towing arrays, the towing cable is in the form of a main cable with branch cables, and must possess properties such as small outer diameter, low density, high strength, flexible bending characteristics, reliable watertightness, excellent resistance to seawater corrosion and abrasion, and the ability to be repeatedly deployed and retrieved.

[0003] Currently, tow cables used in non-uniform cable underwater towed arrays cannot simultaneously achieve the above functions, such as low density, high strength, and flexible bending characteristics. Therefore, it is imperative to design a watertight cable that meets all the above requirements. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a watertight armored branch cable that is tensile and pressure resistant, possessing properties such as small outer diameter, low density, high strength, flexible bending characteristics, reliable watertightness, excellent resistance to seawater corrosion and abrasion, and reusability.

[0005] The technical solution adopted by the present invention to solve its technical problem is as follows:

[0006] A watertight armored branch cable with tensile and pressure resistant properties includes a main cable, a branch cable, a clamp, an armor layer, a vulcanized package, and an inner liner; one or more branch cables are led out from the main cable; an inner liner is provided at the branch point between the main cable and the branch cable, and the inner wall of the inner liner is filled with a vulcanized package between the main cable and the branch cable; the outer side of the main cable and the inner liner (6) is the armor layer; the armor layer, the inner liner, and the main cable are clamped together by clamps.

[0007] Preferably, the main cable and branch cables are one of electrical cables, optical cables, or optoelectronic composite cables.

[0008] Preferably, the main cable and branch cables are further provided with a sheath, which is made of polyurethane, polyvinyl chloride or chloroprene rubber.

[0009] Preferably, the inner liner has a rotating split structure and is made of one of the following materials: titanium alloy, stainless steel, aluminum alloy, or polymer.

[0010] Preferably, the outer middle part of the inner liner is provided with several short columns to evenly divide and position the armor layer.

[0011] Preferably, the clamp is in the form of a hose clamp and is made of stainless steel or titanium alloy.

[0012] Preferably, the armor layer is made of either steel wire or aramid fiber.

[0013] Preferably, when the armor layer is made of aramid fiber, it is wrapped with strong adhesive tape on its outer side.

[0014] Preferably, the vulcanizing package is made of vulcanized rubber or chloroprene rubber.

[0015] The beneficial effects of this invention are as follows:

[0016] While ensuring the watertightness of the main cable and branch cables, the armored cable can directly bear force while transmitting signals through the tensile strength of the armor layer and the signal transmission of the main cable and branch cables. In addition, it also has flexible bending characteristics, excellent resistance to seawater corrosion and abrasion, and can be repeatedly deployed and retracted. Attached Figure Description

[0021] The present invention will be further described and illustrated below with reference to the accompanying drawings and specific embodiments. Obviously, the described examples are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0022] like Figure 1 and Figure 2As shown, the present invention provides a watertight armored branch cable with tensile and pressure resistant properties, comprising a main cable 1, branch cables 2, clamps 3, an armor layer 4, a vulcanized sheath 5, and an inner sleeve 6. One or more branch cables 2 can be led out from the main cable 1, and an inner sleeve 6 covers the branching point between the main cable 1 and the branch cables 2. The surface of the main cable 1 and the inner sleeve 6 is covered with the armor layer 4, which is used to withstand tensile force and prevent the main cable from being directly stressed. The inner wall of the armor layer 4 is filled with vulcanized sheath 5 between itself and the main cable 1 and the branch cables 2, and the outer side of the main cable 1 and the inner sleeve 6 is the armor layer 4. The armor layer 4, the inner sleeve 6, and the main cable 1 are clamped together by the clamps 3 to prevent the armor layer 4 from collapsing during the tensile process of the main cable 1, while also allowing the inner sleeve 6 to withstand the pressure generated by the armor layer 4 under tension, preventing it from directly acting on the main cable 1. In the embodiments of the present invention, the clamps 3 are made of stainless steel or titanium alloy.

[0023] The main cable can be one of the following: cable, optical cable, or optoelectronic composite cable; correspondingly, the branch cable can also be one of these.

[0024] Preferably, the outer sides of the main cable 1 and the branch cable 2 may also be covered with a sheath, the material of which is one of polyurethane, polyvinyl chloride or neoprene rubber, and polyurethane is preferred in this embodiment of the invention.

[0025] Preferably, the inner wall of the inner sleeve 6 is filled with a vulcanized bag 5 between the main cable 1 and the branch cable 2 to ensure the water tightness of the branch structure. The material of the vulcanized bag 5 can be vulcanized rubber or chloroprene rubber. In this embodiment of the invention, chloroprene rubber is preferred.

[0026] Preferably, the outer side of the main cable 1 and the inner liner 6 is an armor layer 4. The material of the armor layer 4 is either steel wire or aramid fiber. Both steel wire and aramid fiber have flexible bending characteristics and excellent wear resistance. In addition, aramid fiber is resistant to seawater corrosion, and galvanized or phosphated steel wire rope is also resistant to seawater corrosion. Therefore, the armored cable has flexible bending characteristics, excellent seawater corrosion resistance and wear resistance. In this embodiment of the invention, aramid fiber is preferred, and its outer side is wrapped with strong adhesive tape.

[0027] like Figure 3 As shown, the inner sleeve 6 is a rotating body or a split rotating body structure. In this embodiment of the invention, the inner sleeve 6 is divided into two sub-inner sleeves, each with a branch opening for the passage of branch cables. Several short uprights are provided in the middle of the outer side of the inner sleeve 6 to evenly distribute and position the armor layer. The material of the inner sleeve 6 can be selected from titanium alloy, stainless steel, aluminum alloy, or polymer materials. Both ends of the inner sleeve 6 have hollow cylindrical fixed ends, on which clamps 3 fix the armor layer 4, the inner sleeve 6, and the main cable 1.

[0028] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the invention. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention. Therefore, all technical solutions obtained through equivalent substitution or transformation fall within the protection scope of the present invention.
