Example Embodiment

[0028] Example 1

[0029] like figure 1 A moisture-proof floating cable, including a cable core, moisture-proof protective layer, and outer sheath 1 internally disposed, and the cable core is provided with at least two cable cores 8 (three shown in the figure. Cable core 8); the outer sleeve of the core is provided with an isolation layer 9, the separator 9 being a shielded layer, the moisture-proof protection layer including an internal oral layer 5, a rotating sleeve 4, and an outside of the inwardly Moisture-proof layer 2, such as image 3 As shown, the inner moisture-proof layer 5 is wound arrangement, and is covered with the outer side of the isolation layer 9, and the inner end side 51 of the inner moisture-proof layer 5 is fixed to the isolation layer 9, the rotation sleeve 4 sets The outer side of the moisture-proof layer 5, and the outer end side 52 of the moisture-proof layer 5 is fixed to the rotating sleeve 4; Figure 4 As shown, the outer surface of the rotation sleeve ...

Example Embodiment

[0035] Example 2

[0036] This example is different from that of Example 1 in:

[0037] In the present embodiment, the isolation layer 9 is a waterproof bandwinding layer.

[0038] In the present embodiment, the inner moisture-proof layer 5 forms a portion corresponding to a portion of the double layer structure is 180 °.

[0039] In this embodiment, if figure 1 As shown, the center of the core is provided with a reinforcing rope 7 extending in the longitudinal direction of the cable, and the reinforcing rope 7 is a Kevra fiber rope. Kevra fiber rope can greatly increase the tensile properties of the cable body, thereby increasing the load capacity of the floating cable.

[0040] In this embodiment, if figure 1 As shown, the isolation layer 9 is provided with a filler 14 between the respective cable cores 8, the filler 14 being hollow short fibers. Hollow short fibers can achieve the filling function of the filler 14, and the interior of hollow short fibers can be reduced, which i...

Abstract

The invention discloses a moisture-proof floating cable, and belongs to the field of cables. The moisture-proof floating cable comprises a cable core, a moisture-proof protection layer and an outer sheath; the outer side of the cable core is sleeved with an isolation layer, the moisture-proof protection layer comprises an inner moisture-proof layer, a rotating sleeve and an outer moisture-proof layer, the inner moisture-proof layer is arranged on the outer side of the isolation layer in a winding mode, and the inner end side of the inner moisture-proof layer is fixedly connected to the isolation layer; the inner damp-proof layer is sleeved with the rotating sleeve, and the outer end side of the inner damp-proof layer is fixedly connected to the rotating sleeve. Raised lines are fixed on the outer surface of the rotating sleeve along the circumferential side at equal intervals; water swelling structures in one-to-one correspondence with the raised lines are fixed on the inner side surface of the outer damp-proof layer along the circumferential side of the outer damp-proof layer; the water swelling structure comprises a water swelling body, a blocking assembly and an elastic body, the inner side face of the water swelling body makes contact with the outer side face of the rotating sleeve, and one side face of the water swelling body makes contact with one corresponding protruding strip. The floating function of the floating cable can be effectively achieved, the damp-proof structure is ingenious in design, and the good damp-proof effect is achieved.

Description

technical field [0001] The invention relates to the field of cables, in particular to a moisture-proof floating cable. Background technique [0002] A cable is a tool composed of multiple wires to transmit electrical energy or electrical signals. With the continuous progress of society, the use of electrical energy and electrical signals is becoming more and more common. Cables have become an indispensable part of our lives. In waters such as oceans and rivers, due to the rapid development, mechanical equipment is needed, so cables are also needed for power supply and communication, and ordinary cables are difficult to support on the water surface, so floating cables are produced. [0003] Floating cables are cables that float on the water surface during use. Due to long-term contact with water during application, floating cables need to have strong waterproof and moisture-proof performance. However, the existing floating cables mostly rely on waterproof sheaths and waterpro...
