Description

Technical Field

[0001] This utility model relates to the field of cables, and more specifically, to a marine cable capable of preventing twisting. Background Technology

[0002] Marine cables are electrical wires and cables specifically designed for power, lighting, control, and communication transmission in various river and sea vessels, as well as in near-shore or offshore structures. Marine cables ensure the safety of ships and play a crucial role in shipbuilding.

[0003] Marine cables, installed on ships, are subject to the swaying and rolling of the vessel due to natural factors such as wind, waves, and currents. Traditional marine cables often lack sufficient support and restraint, making them prone to twisting and rotation under external forces, which can easily lead to cable joint detachment. This not only affects the normal use of the cables but may also threaten the safe operation of the ship. Utility Model Content

[0004] The present invention aims to overcome the defects of the prior art and provide a marine cable that can prevent twisting.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a marine cable, comprising a cable body and multiple fixing units. The cable body, from the outside to the inside, includes an outer sheath, an armor layer, a waterproof layer, a shielding layer, a wrapping layer, and a filling layer. The filling layer contains two conductors, each conductor including a conductor and an insulating layer covering the conductor. The fixing unit includes a limiting frame and a rubber sleeve. The limiting frame has an Ω-shaped cross-section, and the rubber sleeve is cubic. The outer wall of the rubber sleeve has a fixing groove, and the limiting frame is accommodated in the fixing groove. Both ends of the limiting frame have mounting holes. The rubber sleeve has a through hole through which the cable body passes. The inner wall of the rubber sleeve is fixed to the outer wall of the cable body by adhesive.

[0006] Furthermore, the width of the limiting frame in the length direction of the cable body is smaller than the width of the fixing groove in the length direction of the cable body.

[0007] This allows the cable body to move back and forth a certain amount of space, giving it room for adjustment during installation.

[0008] Furthermore, the fixing unit has at least two units.

[0009] This makes the cable installation more secure.

[0010] Furthermore, the limiting frame includes a U-shaped frame and two end plates that are fixedly connected to both ends of the U-shaped frame, the mounting hole is located at the end plate, the fixing groove has a U-shaped structure, and the U-shaped frame is accommodated in the fixing groove.

[0011] This allows for easy fixing of the mounting unit to the cable tray through perforation.

[0012] Furthermore, the armor layer is a steel strip armor layer.

[0013] This improves the mechanical properties of the cable.

[0014] Furthermore, the waterproof layer is made of polyurethane material.

[0015] This enhances the cable's waterproof performance.

[0016] Furthermore, the shielding layer is a copper wire braided shielding layer.

[0017] Therefore, the cable has good shielding effect.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. The marine cable of this application provides stable support and limit for the cable through the fixing unit, which effectively prevents the cable from twisting or rotating due to external forces during use.

[0020] 2. In the marine cable of this application, the width of the limiting frame is smaller than the width of the fixing groove, so that the cable body has a certain space for forward and backward movement within the limiting frame, thereby facilitating the installation and adjustment of the cable.

[0021] 3. The marine cable of this application has good mechanical properties, waterproof properties, and shielding properties, which enhances the durability and service life of the cable. Attached Figure Description
