Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, specifically a multi-layer protective structure for ship cables resistant to seawater corrosion. Background Technology

[0002] Ships navigate in the marine environment for extended periods, exposing cables to a variety of harsh environmental factors, including seawater erosion, salt spray corrosion, humidity, high and low temperatures, vibration, and impact. Inadequate cable protection can lead to decreased insulation performance, corrosion of metallic components, and reduced mechanical strength, thus affecting the normal operation of the cables and the safe operation of the ship.

[0003] Most cables currently in use lack high-temperature resistance and fire resistance, tensile and compressive strength, and are unable to prevent external electromagnetic interference. During use, if the cable lacks high-temperature resistance, it may experience short circuits or other faults when used near high-temperature areas such as ship engines. If the cable lacks fire resistance, it may not effectively prevent the spread of flames in the event of a fire, failing to provide safety for the ship. This results in poor safety and practicality. When using cables on ships, the vibrations generated during navigation can easily cause the cable to stretch and deform if it lacks sufficient tensile strength, damaging its electrical performance. This can lead to signal transmission interruptions and distortions, as well as hindered power transmission and even short circuits. Furthermore, ships have numerous pieces of equipment and limited space, making electrical... Cables typically need to be laid in complex channels. If the cable's compressive strength is poor, it can be damaged under pressure, rendering it unusable. This also reduces the cable's overall strength. Furthermore, if the cable cannot prevent external electromagnetic interference, it can lead to a decline in communication signal quality, causing noise and distortion during signal transmission, resulting in incorrect or lost information transmission. This can affect communication between different departments on board and with the outside world, making the cable impractical. Additionally, the cable is susceptible to seawater corrosion. Seawater is corrosive, and if the cable is not corrosion-resistant, its exterior will gradually deteriorate, exposing the internal conductive core and significantly increasing the risk of short circuits. This could potentially cause electrical fires, directly threatening the lives of ship personnel, making the cable unsafe to use. Utility Model Content

[0004] The purpose of this invention is to provide a multi-layer protective structure for marine cables that is resistant to seawater corrosion, in order to solve the problems raised in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer protective structure for a seawater corrosion-resistant ship cable, comprising a cable body, a protective mechanism provided on the outer wall of the cable body, the protective mechanism comprising a cross-linked polyethylene layer, the cross-linked polyethylene layer fixedly attached to the outer wall of the cable body, a copper mesh fixedly connected to the outer wall of the cross-linked polyethylene layer, an aluminum hydroxide layer fixedly connected to the outer wall of the copper mesh, a copper alloy layer fixedly connected to the outer wall of the aluminum hydroxide layer, and a glass fiber layer fixedly connected to the outer wall of the copper alloy layer.

[0006] As a preferred technical solution, the cross-linked polyethylene layer is cylindrical in shape, and the shape and size of the cross-linked polyethylene layer match the shape and size of the cable body.

[0007] As a preferred technical solution, the aluminum hydroxide layer is cylindrical in shape, and the shape and size of the aluminum hydroxide layer match the shape and size of the copper mesh.

[0008] As a preferred technical solution, the copper alloy layer is cylindrical in shape, and the shape and size of the copper alloy layer match the shape and size of the aluminum hydroxide layer.

[0009] As a preferred technical solution, the shape and size of the glass fiber layer match the shape and size of the copper alloy layer, and the shape of the glass fiber layer is the same as that of the copper alloy layer.

[0010] As a preferred technical solution, the outer wall of the glass fiber layer is provided with a nickel alloy layer, and the shape and size of the nickel alloy layer match the shape and size of the glass fiber layer.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the design of its protective mechanism, enables the cable to possess high-temperature resistance, fire resistance, tensile and compressive strength, and protection against external electromagnetic interference. During use, the cross-linked polyethylene layer and aluminum hydroxide layer provide high-temperature resistance and fire resistance, while the copper alloy layer and glass fiber layer provide tensile and compressive strength. The copper mesh prevents the cable from being affected by external electromagnetic interference. This design avoids short circuits and other malfunctions that might occur when the cable is used near high-temperature areas such as ship engines due to a lack of high-temperature resistance. It also prevents the cable from failing to effectively prevent the spread of flames in the event of a fire or other external situation, thus ensuring the safety of the ship. This design ensures the cable's safety and practicality, preventing situations where insufficient tensile strength leads to cable deformation, damage to electrical performance, signal transmission interruptions or distortions, power transmission obstruction, or even short circuits. It also avoids situations where poor compressive strength damages the cable's internal structure, rendering it unusable. This guarantees the cable's strength and prevents communication signal quality degradation, noise and distortion during signal transmission, and information errors or loss that could affect communication between ship departments and the outside world. Ultimately, this design guarantees the cable's practicality.

[0013] 2. This utility model, through the setting of a nickel alloy layer, can prevent seawater from corroding the cable. During use, the corrosion resistance of the nickel alloy layer itself prevents seawater from corroding the cable. This avoids the situation where the cable is not corrosion-resistant, which would gradually damage the cable's exterior and expose the internal conductive core, greatly increasing the risk of short circuits and potentially causing electrical fires, posing a direct threat to the lives of ship personnel. This ensures the safety of the cable during use. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides the following technical solution, including a cable body 1, a protective mechanism 2 provided on the outer wall of the cable body 1, and a nickel alloy layer 3 provided on the outer wall of the glass fiber layer 205.

[0020] Specifically: When the cable body 1 is required, the protective mechanism 2 enables the cable body 1 to simultaneously possess the ability to resist high temperature and fire, resist tensile and compressive stress, and prevent external electromagnetic interference. Seawater has a certain degree of corrosiveness. When seawater corrodes the cable body 1, the nickel alloy layer 3 is used to prevent seawater from corroding the cable body 1, thereby completing the work.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, a protective mechanism 2 is provided on the outer wall of the cable body 1. The protective mechanism 2 includes a cross-linked polyethylene layer 201. The cross-linked polyethylene layer 201 is fixedly attached to the outer wall of the cable body 1. A copper mesh 202 is fixedly connected to the outer wall of the cross-linked polyethylene layer 201. An aluminum hydroxide layer 203 is fixedly connected to the outer wall of the copper mesh 202. A copper alloy layer 204 is fixedly connected to the outer wall of the aluminum hydroxide layer 203. A glass fiber layer 205 is fixedly connected to the outer wall of the copper alloy layer 204. The cross-linked polyethylene layer 201 is cylindrical in shape, and its shape and size match the shape and size of the cable body 1. The aluminum hydroxide layer 203 is cylindrical in shape, and its shape and size match the shape and size of the copper mesh 202. The copper alloy layer 204 is cylindrical in shape, and its shape and size match the shape and size of the aluminum hydroxide layer 203. The glass fiber layer 205 is also cylindrical in shape, and its shape is the same as that of the copper alloy layer 204.

[0022] Specifically: When the cable body 1 is used near high-temperature areas such as ship engines, the cross-linked polyethylene layer 201 prevents short circuits or malfunctions, giving the cable body 1 high-temperature resistance. When there is electromagnetic interference near the cable body 1, the copper mesh 202 acts as a shielding layer to prevent external electromagnetic interference from affecting the signal transmission of the cable body 1. In case of fire, the aluminum hydroxide layer 203 acts as a flame retardant, effectively preventing the spread of flames and providing safety for the ship. When the ship is sailing, vibrations occur, and the copper alloy layer 204 increases the strength of the cable body 1, preventing the conductors in the cable body 1 from being damaged or broken due to vibration or pulling, while maintaining good conductivity. When the cable body 1 is used on a ship and is squeezed by heavy objects, the glass fiber layer 205 gives the cable body 1 a certain compressive strength, preventing the cable body 1 from being crushed, thus completing the protection work.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, a nickel alloy layer 3 is provided on the outer wall of the glass fiber layer 205, and the shape and size of the nickel alloy layer 3 match the shape and size of the glass fiber layer 205.

[0024] Seawater has a certain degree of corrosiveness. When seawater corrodes the cable body 1, a nickel alloy layer 3 is set to prevent seawater from corroding the cable body 1. The nickel alloy layer 3 has strong corrosion resistance, especially in chlorinated seawater environments. This alloy can form a dense passivation film on the cable surface, preventing seawater from further eroding the cable body 1, thereby completing the anti-corrosion work.

[0025] The working principle of this utility model is as follows: When the cable body 1 is used near high-temperature areas such as ship engines, the cross-linked polyethylene layer 201 prevents short circuits or malfunctions, giving the cable body 1 high-temperature resistance. When there is electromagnetic interference near the cable body 1, the copper mesh 202 acts as a shielding layer to prevent external electromagnetic interference from affecting the signal transmission of the cable body 1. In case of fire, the aluminum hydroxide layer 203 acts as a flame retardant, effectively preventing the spread of flames and providing safety for the ship. When the ship is sailing, vibrations occur; the copper alloy layer 204 increases the strength of the cable body 1, making the cable body... The conductor in cable 1 will not be damaged or broken due to vibration or pulling, and can maintain good conductivity. When cable body 1 is used on a ship, when cable body 1 is squeezed by heavy objects, the glass fiber layer 205 gives cable body 1 a certain compressive strength, so that cable body 1 will not be crushed, thus completing the protection work. Seawater has a certain degree of corrosiveness. When seawater corrodes cable body 1, the nickel alloy layer 3 is set to prevent seawater from corroding cable body 1. The nickel alloy layer 3 has strong corrosion resistance, especially in chlorinated seawater environment. This alloy can form a dense passivation film on the cable surface, preventing seawater from further eroding cable body 1, thus completing the anti-corrosion work.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
