Description

Technical Field

[0001] This utility model relates to the field of marine cable technology, specifically a marine cable with a multi-layer waterproof sheath structure. Background Technology

[0002] Cables are made of one or more insulated conductors twisted together and covered with a metal shell and an insulating protective layer. They have functions such as moisture resistance, temperature resistance, abrasion resistance and shielding. Because ship designs are usually quite complex, internal cable connections are complex, and ships usually sail on the sea for long periods of time, the working environment of cables on ships is relatively poor.

[0003] A search revealed a marine cable with Chinese patent authorization announcement number CN220367767U, comprising several strands of wire cores arranged in a circular array. Each strand includes a tin-plated copper conductor. The strands are wrapped together by a ceramicized fire-resistant composite tape. An aluminum-plastic composite tape is then wrapped around the ceramicized fire-resistant composite tape, and an outer sheath is also wrapped around the aluminum-plastic composite tape. While this cable possesses a reasonable structural arrangement and excellent waterproof and salt spray corrosion resistance, its waterproof performance is poor, allowing water to easily penetrate and cause short circuits. Furthermore, the cable has poor compressive strength, making it prone to damage and breakage under external pressure and impact, thus reducing its service life. Therefore, we propose an improvement: a marine cable with a multi-layered waterproof sheath structure. Utility Model Content

[0004] The purpose of this invention is to address the problems of poor waterproofing performance in current devices, which allow water to easily enter the cable and cause short circuits, as well as poor compressive strength, making the cable prone to damage and breakage after being subjected to external pressure and impact, thus reducing the cable's service life.

[0005] To achieve the above-mentioned utility model objectives, the present utility model provides the following technical solution: by utilizing the pressure deformation of the natural rubber buffer tube, the external force on the cable body is buffered and weakened, and in conjunction with the gas stored between the air storage ring and the seal, the cable body can be used while suspended on the water surface, thereby improving the above-mentioned problems.

[0006] The application is as follows:

[0007] A marine cable with a multi-layered waterproof sheath structure includes a cable body, comprising: a wrapping tape, a waterproof sheath assembly, a shielding component, and a main conductor.

[0008] The waterproof sleeve assembly includes an inner sheath, a buffer tube fixedly connected to the outer surface of the inner sheath, and a water-blocking strip fixedly connected to the outer surface of the buffer tube.

[0009] The shielding component includes a shielding post, a support frame fixedly connected to the outer surface of the shielding post, and a metal shielding layer fixedly connected to the outer surface of the support frame.

[0010] As a preferred technical solution of this application, an outer sheath is fixedly connected to the outer surface of the water-blocking strip, and a filling layer is filled between the inner sheath and the main core.

[0011] As a preferred technical solution of this application, an air storage ring is fixedly connected to the outer surface of the outer sheath, and a seal is fixedly connected to the open end of the air storage ring;

[0012] As a preferred technical solution of this application, the water-blocking strip is made of water-blocking yarn, and the buffer tube is made of natural rubber.

[0013] As a preferred technical solution of this application, the inner sheath is made of high-density polyethylene, and the outer sheath is made of chlorinated polyethylene;

[0014] As a preferred technical solution of this application, the shielding column is made of conductive carbon black filled TPE, the support frame is made of tin-plated copper mesh, and the metal shielding layer is made of aluminum foil.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the scheme of this application:

[0017] (1) By setting up a waterproof sleeve, the pressure deformation of the natural rubber buffer tube can be used to buffer and weaken the external force on the cable body. In conjunction with the gas stored between the air storage ring and the seal, the cable body can be suspended on the water surface, avoiding the cable body from contacting the ship hull and being rubbed or collided with the spiral blades. The combination of the water-blocking strip and the inner sheath makes the cable body waterproof in multiple layers, increasing the service life of the cable body.

[0018] (2) By using shielding posts, support frames and metal shielding layers in combination, the shielding posts made of conductive carbon black filled TPE and the metal shielding layers made of aluminum foil can increase the cable body's resistance to environmental magnetic field interference. The cable body can solve the electromagnetic compatibility problem in high-power charging through the synergistic effect of high-frequency reflection, low-frequency absorption and gap filling.

[0031] The waterproof sleeve 3 includes an inner sheath 31, a buffer tube 32 is fixedly connected to the outer surface of the inner sheath 31, and a water-blocking strip 33 is fixedly connected to the outer surface of the buffer tube 32.

In conjunction with the gas stored between the air storage ring 34 and the seal 35, the cable body 1 can be suspended on the water surface for use, avoiding the cable body 1 from contacting the hull and being rubbed or collided with the spiral blades. Furthermore, the cooperation between the water-blocking strip 33 and the inner sheath 31 enables the cable body 1 to be waterproofed in multiple layers, increasing the service life of the cable body 1.
