Description

Technical Field

[0001] The 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 sailing at sea, the surrounding humidity is extremely high, and seawater may contact the cable at any time for various reasons. If the cable is not waterproof and moisture-proof, the intrusion of water will seriously affect the insulation performance of the cable. Water, especially salty seawater, will accelerate the corrosion of the cable's metal parts, reducing the mechanical strength and service life of the cable. Water entering the cable may cause the insulation resistance to drop, causing leakage or even short circuit, which poses 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 long-term corrosion of the cable skin. 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 be dissipated 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 aims at the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technologies. 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 cannot process surface attachments, resulting in corrosion of the cable skin.

[0005] The embodiment of the present invention adopts the following technical solution: a watertight and anti-corrosion 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 arranged on the intermediate protective layer for heat dissipation.

[0006] Furthermore, the anti-corrosion external protection mechanism includes a connecting sleeve and a plurality of arc blocks, the connecting sleeve is arranged on the middle protective layer, the arc block is arranged on the outside of the connecting sleeve, 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 arranged at the end of the arc block on the side where the fixed block is located, and a plurality of the arc blocks are staggeredly contacted with each other through the elastic contact blocks, a plurality of air holes are opened at the center position of the arc segment of the arc block, and a plurality of blocking blocks corresponding to the positions of the air holes are arranged 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 capable of resetting their deformation are arranged in the arc block.

[0008] Furthermore, the elastic contact block is made of a plastic 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 connection 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 beneficial effects of the present invention are: Firstly, during use, although an additional layer of anti-corrosion outer protection mechanism is set outside the middle protective layer, air holes are set 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, affected by the shape of the arc block, the attachment will be on the lowest layer of the arc block during the attachment process, resulting in a concentrated attachment. 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 increases, 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 a concave shape to a convex shape, and automatically detaches the attachments accumulated in the arc plate, thereby preventing the particles from adhering to the arc block for a long time, causing the arc block to corrode. By using the anti-corrosion external protection mechanism, the attachment position can be limited while ensuring the heat dissipation performance of the cable, so that it can be attached to a specific place. Then, by using the deformation of the arc block after attachment and the characteristics that it will affect the heat dissipation of the cable and cause the cable temperature to rise after attachment, the loosening of the particles is promoted by temperature, which can facilitate processing in the later processing 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 the particles.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0019] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] Combine the following Figures 1 to 3 As shown, an embodiment of the present invention provides a watertight and anti-corrosion composite cable for ships, including an inner core layer 1 for protecting the wire core, and also includes an intermediate protective layer 2 for protecting the inner core layer 1 to improve the protective performance, and an anti-corrosion outer protection mechanism 3 for placing corrosion caused by attachments on the surface, and a plurality of through holes are provided on the intermediate protective layer 2 for heat dissipation.

[0021] Specifically, the anti-corrosion external protection mechanism 3 includes a connecting sleeve 37 and a plurality of 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 arranged at the end of the arc block 32 on the side where the fixed block 36 is located, and a plurality of the arc blocks 32 are staggeredly contacted with each other through the elastic contact blocks 34, a plurality of air holes 31 are opened at the center position of the arc segment of the arc block 32, and a plurality of blocking blocks 33 corresponding to the positions of the air holes 31 are arranged between the connecting sleeve 37 and the arc block 32.

[0022] 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 self-discharged, thereby avoiding long-term attachment of the particles.

[0023] Specifically, the arc block 32 is made of a soft and bendable material, and a plurality of memory alloys capable of resetting the deformation are arranged in the arc block 32 .

[0024] During operation, due to the material characteristics of the arc block 32, the arc block 32 can be deformed more seriously under the action of weight. Although a memory alloy is arranged 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.

[0025] 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 .

[0026] During operation, the arc block 32 will bend, while the total length of the arc block 32 remains unchanged. Therefore, after the arc block 32 bends, a gap will appear between the arc block 32 and another 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.

[0027] Specifically, the movable connection block 35 is made of shape memory deformation material.

[0028] During operation, the movable connecting block 35 cooperates with the arc block 32 to deform.

[0029] Specifically, the blocking block 33 is arranged at the lowest point of the arc block 32, and the arc block 32 is connected to the connecting sleeve 37 through the fixing block 36, so that when the arc block 32 is bent 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.

[0030] 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 the side wall of the arc block 32, there is a downward gravity trend, and when attaching, the surface is actually easiest to adhere, just like dust accumulates on the surface of an object), thereby achieving a concentrated attachment. At this time, as the attachment continues, the weight of the arc block 32 becomes heavier, causing the deformation of the arc block 32 to intensify. At this time, 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 an obvious change in the 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 increases, the attached particles will become loose (because salt particles will be difficult to dissipate at high temperatures). The arc block 32 is formed by the memory alloy being reset and bulged, and the concave shape is changed into the convex shape, and the attachment accumulated in the arc plate is automatically separated, so as to avoid the particles from being attached to the arc block 32 for a long time, resulting in the corrosion of the arc block 32. At this time, the air vent 31 is opened, and the temperature is gradually dissipated. After the temperature is lowered, the memory alloy is reset, so as to carry out the next treatment. The present invention utilizes the anti-corrosion outer protection mechanism 3. On the premise of ensuring the heat dissipation performance of the cable, the attachment position can be limited, so that it is 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 temperature of the cable to rise after attachment are utilized. The loosening between the particles is promoted by temperature, which can be convenient for processing in the later processing. Secondly, the temperature characteristics are utilized to change the shape of the arc block 32, so as to discharge the accumulated particles by themselves, so as to avoid the long-term attachment of the particles.

[0031] 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 aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
