A watertight and corrosion-resistant composite cable for ships

Abstract

The present invention discloses a watertight and corrosion-resistant composite cable for ships, which relates to the field of cable technology. The cable comprises an inner core layer for protecting the wire core, an intermediate protective layer for protecting the inner core layer and improving its protective performance, and an outer anti-corrosion protective mechanism for placing surface attachments that cause corrosion. The intermediate protective layer is provided with a plurality of through holes for heat dissipation. When the cable is in use, the outer anti-corrosion protective mechanism is used to limit the attachment position while ensuring the heat dissipation performance of the cable, so that the cable is attached to a specific location. The cable then utilizes the deformation of the arc block after attachment, and the characteristics of the arc block affecting the heat dissipation of the cable and causing the cable temperature to rise, to promote loosening between particles through temperature, which facilitates handling during later processing. The temperature characteristics are then used to change the shape of the arc block, thereby self-discharging the accumulated particles, thereby avoiding the long-term attachment of the particles.

Description

Technical Field

[0001] The present invention relates to the technical field of cables, and in particular to a watertight and corrosion-resistant composite cable for ships. Background Art

[0002] When a ship is at sea, the surrounding humidity is extremely high, and seawater may contact cables at any time for various reasons. If the cable is not waterproof and moisture-resistant, the intrusion of water will seriously affect the cable's insulation performance. Moisture, especially salty seawater, can accelerate the corrosion of the cable's metal components, reducing the cable's mechanical strength and service life. Moisture entering the cable can cause a decrease in insulation resistance, leading to leakage and even short circuits, posing a serious threat to the ship's electrical system and personnel safety.

[0003] However, during the use of existing ship cables, due to the cable's own characteristics and the environment in which it is located, salt particles and biofilm will adhere to the cable surface after long-term use. At this time, the cable itself is unable to deal with the attached salt particles, resulting in the cable surface being corroded over time. When the cable surface is corroded and enters the inner core layer, it will affect the performance of the internal cable. At the same time, if a large number of wrapping layers are used to avoid corrosion, the cable needs to dissipate heat during use. Excessive temperature will also affect the performance of the cable, resulting in the wrapping layer not being too thick. Summary of the Invention

[0004] The technical solution of the present invention addresses the technical problem that the existing technical solutions are too simple and provides a solution that is significantly different from the existing technology. An embodiment of the present invention provides a watertight and corrosion-resistant composite cable for ships to solve the technical problem that the existing cables are unable to process surface attachments, resulting in corrosion of the cable surface.

[0005] The embodiment of the present invention adopts the following technical solution: a watertight and corrosion-resistant composite cable for ships, including an inner core layer for protecting the wire core, and an intermediate protective layer for protecting the inner core layer to improve the protective performance, and an anti-corrosion outer protection mechanism for placing corrosion caused by attachments on the surface, and a plurality of through holes are provided on the intermediate protective layer for heat dissipation.

[0006] Furthermore, the anti-corrosion external protection mechanism includes a connecting sleeve and several arc blocks, the connecting sleeve is arranged on the middle protective layer, the arc block is arranged on the outside of the connecting sleeve, and a fixed block and a movable connecting block are respectively passed between the arc block and the connecting sleeve, and the fixed block and the movable connecting block are respectively located on both sides of the arc block, and the positions of the fixed block and the movable connecting block correspond to each other. An elastic contact block is provided at the end of the arc block on the side where the fixed block is located, and several of the arc blocks are staggered in contact with each other through the elastic contact blocks. Several air holes are opened at the center position of the arc segment of the arc block, and several blocking blocks corresponding to the positions of the air holes are provided between the connecting sleeve and the arc block.

[0007] Furthermore, the arc block is made of a soft and bendable material, and a number of memory alloys that can reset their deformation are arranged in the arc block.

[0008] Furthermore, the elastic contact block is made of a plastically deformable material, so that the lower surface of the elastic contact block is always in contact with the upper surface of the arc block.

[0009] Furthermore, the movable connecting block is made of shape memory deformation material.

[0010] Furthermore, the blocking block is arranged at the lowest point of the arc block, and the arc block is positionally connected through the fixing block and the connecting sleeve.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] First, during use, although an additional layer of anti-corrosion outer protection mechanism is added outside the middle protective layer, air holes are provided on the outermost layer to ensure the heat dissipation effect of the cable. Secondly, during use, particles will inevitably adhere to the outer surface of the arc block. However, due to the shape of the arc block, the attachment will be concentrated on the lowest layer of the arc block during the attachment process. At this time, as the attachment continues, the weight of the arc block becomes heavier, causing the deformation of the arc block to increase. At this time, the air holes are blocked, and the temperature generated by the cable is accumulated and cannot be dissipated. As the temperature of the cable gets higher and higher, the attached particles will become loose (because salt particles are difficult to form at high temperatures, and high temperatures can promote the particles to form). The tightness becomes worse, causing it to loosen) As the temperature rises, the memory alloy in the arc block resets and bulges, changing from concave to convex, and automatically detaches the attachments accumulated in the arc plate, thereby preventing particles from adhering to the arc block for a long time, causing corrosion of the arc block. By using this anti-corrosion external protection mechanism, while ensuring the heat dissipation performance of the cable, the attachment position can be limited to focus on a specific place, and then the deformation of the arc block after attachment and the characteristics of affecting the heat dissipation of the cable and causing the cable temperature to rise after attachment are used to promote loosening between the particles through temperature, which can facilitate processing in the later process. Secondly, the temperature characteristics are used to change the shape of the arc block, so that the accumulated particles are discharged by themselves, thereby avoiding the long-term attachment of particles.

[0019] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] The components of the embodiments of the present invention generally described and shown in the drawings herein may be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the invention.

[0021] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0024] The following combination Figures 1 to 3 As shown, an embodiment of the present invention provides a watertight and corrosion-resistant composite cable for ships, including an inner core layer 1 for protecting the wire core, an intermediate protective layer 2 for protecting the inner core layer 1 and improving the protective performance, and an anti-corrosion outer protection mechanism 3 for placing corrosion caused by attachments on the surface. The intermediate protective layer 2 is provided with a plurality of through holes for heat dissipation.

[0025] Specifically, the anti-corrosion external protection mechanism 3 includes a connecting sleeve 37 and several arc blocks 32. The connecting sleeve 37 is sleeved on the intermediate protective layer 2. The arc block 32 is arranged on the outside of the connecting sleeve 37. A fixed block 36 and a movable connecting block 35 are respectively passed between the arc block 32 and the connecting sleeve 37, and the fixed block 36 and the movable connecting block 35 are respectively located on both sides of the arc block 32, and the positions of the fixed block 36 and the movable connecting block 35 correspond to each other. An elastic contact block 34 is provided at the end of the arc block 32 on the side where the fixed block 36 is located. Several of the arc blocks 32 are staggered in contact with each other through the elastic contact blocks 34. Several air holes 31 are opened at the center position of the arc segment of the arc block 32, and several blocking blocks 33 corresponding to the positions of the air holes 31 are provided between the connecting sleeve 37 and the arc block 32.

[0026] During operation, the anti-corrosion external protection mechanism 3 can be used to limit the attachment position while ensuring the heat dissipation performance of the cable, so that it can be attached to a specific place. Then, the deformation of the arc block 32 after attachment and the characteristics of affecting the heat dissipation of the cable and causing the cable temperature to rise after attachment are used to promote loosening between the particles through temperature, which can facilitate processing in the later processing process. Secondly, the temperature characteristics are used to change the shape of the arc block 32, so that the accumulated particles can be discharged by themselves, thereby avoiding long-term attachment of the particles.

[0027] Specifically, the arc block 32 is made of a soft and bendable material, and a plurality of memory alloys capable of resettable deformation are provided in the arc block 32 .

[0028] During operation, due to the material properties of the arc block 32, the arc block 32 can be deformed more seriously under the action of weight. At the same time, although a memory alloy is provided inside, the memory alloy is curved. When affected by temperature, the arc block 32 can be displaced. Under normal circumstances, the curved memory alloy will not affect the use of the arc block 32.

[0029] Specifically, the elastic contact block 34 is made of a plastic deformable material, so that the lower surface of the elastic contact block 34 is always in contact with the upper surface of the arc block 32 .

[0030] During operation, the arc block 32 will bend and change, while the total length of the arc block 32 remains unchanged. Therefore, when the arc block 32 bends, a gap will actually appear between the arc block 32 and the other arc block 32. Therefore, in the actual process, the two arc blocks 32 are not fixedly connected to ensure that they can be deformed, and the elastic contact block 34 is set to prevent a gap from appearing between the arc blocks 32.

[0031] Specifically, the movable connecting block 35 is made of shape memory deformation material.

[0032] During operation, the movable connecting block 35 cooperates with the arc block 32 to deform.

[0033] Specifically, the blocking block 33 is set at the lowest point of the arc block 32, and the arc block 32 is positionally connected with the connecting sleeve 37 through the fixing block 36, so that when the arc block 32 bends more severely, the blocking block 33 will be inserted into the air vent 31. At this time, the insertion can resist the particles accumulated on the surface of the arc block 32 to loosen them, and secondly, the air vent 31 can be completely blocked to prevent it from dissipating heat.

[0034] Working principle: During the use of the cable, with continuous use, particles will appear on the surface of the cable. At this time, the particles will adhere to the outer surface of the arc block 32. Affected by the shape of the arc block 32, during the attachment process, the particles will adhere to the lowest layer of the arc block 32 (because when attaching to the side wall of the arc block 32, there is a continuous downward gravity trend, and when attaching, the surface is actually the easiest to adhere to, just like dust accumulates on the surface of an object), thereby achieving a concentrated attachment situation. At this time, as the attachment continues, the weight of the arc block 32 becomes heavier, resulting in the aggravation of the deformation of the arc block 32. When the arc block 32 deforms, it will pull the movable connecting block 35 to move, and the air vent 31 on the arc block 32 with a significantly changed degree of depression will contact the blocking block 33. At this time, the air vent 31 is blocked, and the temperature generated by the cable is accumulated and cannot be dissipated. As the temperature of the cable gets higher and higher, the attached particles will become loose (because salt particles will be difficult to dissipate at high temperatures). The present invention utilizes the anti-corrosion outer protection mechanism 3 to limit the attachment position while ensuring the heat dissipation performance of the cable, so that it can focus on attaching to a specific location, and then utilizes the deformation of the arc block 32 after attachment, and the characteristics of affecting the heat dissipation of the cable and causing the cable temperature to rise after attachment, to promote the loosening of the particles through temperature, which can facilitate the processing in the later processing. Secondly, the temperature characteristics are used to change the shape of the arc block 32, so that the accumulated particles are discharged by themselves, thereby avoiding the long-term attachment of the particles.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
