Description

Technical Field

[0001] This utility model belongs to the field of cable manufacturing technology, specifically relating to an underwater towing cable. Background Technology

[0002] During underwater topographic exploration and search and rescue operations, detectors and their connected cables often face severe challenges from strong or hidden underwater currents. These currents not only introduce significant resistance to the cables but also make the detector's path unpredictable and uncontrollable, thus reducing operational efficiency and, in severe cases, potentially leading to mission failure. As the cable length increases, it faces greater underwater resistance during movement. The longer the cable, the larger its frontal surface area facing the current, resulting in increased fluid resistance and making the cable's internal core more susceptible to damage.

[0003] To address the existing problems, we propose an underwater towing cable. Utility Model Content

[0004] The purpose of this invention is to provide an underwater towing cable to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] It includes a first cable body, a second cable body disposed on the side of the first cable body, and an annular third cable body. The first cable body and the second cable body are disposed inside the third cable body. The first cable body includes a plurality of wire cores, a protective layer covering the wire cores, and a filling portion. Adjacent protective layers are fused together, and the protective layer and the adjacent filling portion are fused together.

[0007] The cross-section of the second cable is triangular, and the bottom surface of the second cable is fused to the adjacent first cable.

[0008] The cross-section of the third cable is triangular, and the top and sides of the cross-section of the third cable are arc-shaped; part of the first cable is fused to the top of the adjacent third cable, and the second cable and the third cable are fused together.

[0009] Preferably, the two curved convex surfaces of the third cable face outwards.

[0010] Preferably, the cross-section of the first cable body is circular.

[0011] Preferably, there are 3 wire cores, and the different wire cores are arranged vertically.

[0012] Preferably, there are 3 wire cores, and the different wire cores are arranged in a triangle.

[0013] Preferably, there are 3 wire cores, and the different wire cores are arranged in an equilateral triangle.

[0014] Preferably, the two sides of the second cable body that are not connected to the first cable body and the third cable body are fused together.

[0015] Preferably, the protective layer, the filling part, the second cable body and the third cable body are all made of thermoplastic materials.

[0016] Preferably, the protective layer, the filling part, the second cable body and the third cable body are all made of polyethylene.

[0017] Preferably, the protective layer, the filling part, the second cable body and the third cable body are all made of polyvinyl chloride.

[0018] In this invention, the protective layer and the filling support in the first cable body are fused together, and the first cable body is formed into a circular structure under the filling of the filling part; this reduces the damage rate of the cable core caused by high resistance underwater.

[0019] The second cable body of this invention is located on the side of the first cable body and fills the space between the first and third cable bodies, ensuring that the shape of the third cable body does not collapse or deform during the manufacturing process.

[0020] The different wire cores of this invention are arranged vertically, which reduces the damage rate of the wire cores caused by high resistance underwater.

[0021] The different wire cores of this invention are arranged in a triangular pattern, which reduces the damage rate of the wire cores caused by high resistance underwater.

[0022] The third cable body of this invention has arc-shaped sides with the convex surface facing outward, which ensures that the resistance brought by the water flow to the cable is reduced.

[0023] Compared with the prior art, the beneficial effects of this utility model are: this utility model not only reduces the resistance of water flow to the cable and stabilizes the cable's running trajectory, but also protects the internal core of the cable from damage.
