Description

Technical Field

[0001] The utility model relates to a cable structure, in particular to a high-strength tensile-resistant shipboard cable structure, belonging to the technical field of cables. Background Art

[0002] Cables are an important component of ship electrical systems. Due to the special operating environment of ships, there are high requirements for the tensile performance of cables. Through the design of the tensile layer, it can withstand the large tensile force generated by factors such as wind and waves during the navigation of the ship.

[0003] In the prior art, the utility model with application number 202222614247.5 discloses a high-strength tensile-resistant cable and a stage cable structure. In order to solve the problem that the cable core and the high-strength fiber filaments arranged on the outside are of similar length, so that the cable core is easily broken when subjected to strong tensile force with the breakage of the fiber filaments, and thus cannot meet the tensile strength requirements of the cable, the cable core and the rubber strip are combined together by cross-winding, so that the actual length of the cable core is significantly increased compared to the steel wire, so that when the cable is subjected to strong tensile deformation, the cable core can maintain its own integrity and avoid damage to the cable. The steel wire is arranged on the outside of the inner insulating layer to protect the inner insulating layer from deformation, thereby ensuring that the cable has good insulation performance. The braided reinforcement layer arranged inside the insulating enamel layer can further enhance the stability of the cable, so that the cable has better tensile performance; the use of the inner tensile self-adhesive tape layer and the outer tensile self-adhesive tape layer makes the combination of the cable core, the inner insulating layer and the steel wire more compact, further improving the use effect of the cable.

[0004] Similar to the above application, there are still some deficiencies:

[0005] The cable is processed by a layer-by-layer coating production method. When subjected to traction, the outer side of the cable is first subjected to a greater tensile force. However, the friction resistance between the layers of the cable is relatively small. When subjected to a large tensile force, the layers are prone to sliding against each other. As a result, the cable is gradually stretched and broken from the outside to the inside, and the cable's tensile strength is poor.

[0006] Therefore, a high-strength tensile-resistant marine cable structure is designed to optimize the above problems. Utility Model Content

[0007] The main purpose of the utility model is to provide a high-strength tensile-resistant shipboard cable structure to solve the problems raised in the above background technology.

[0008] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0009] A high-strength tensile-resistant shipboard cable structure includes a cable core, a waterproof membrane wrapped around the outside of the cable core, a shielding layer wrapped around the outside of the waterproof membrane, and an outer sheath layer outside the shielding layer. The cable cores are evenly distributed inside the waterproof membrane in a ring array. An inner tensile-resistant steel wire is provided in the middle of the cable core. A tensile-resistant filling rope is filled between the outside of the cable core and the waterproof membrane. An inner anti-slip mechanism is provided between the outside of the waterproof membrane and the shielding layer. An outer anti-slip mechanism is provided between the outside of the shielding layer and the outer sheath layer.

[0010] Preferably, the outer side of the inner tensile steel wire is uniformly provided with limiting grooves along the circumferential direction, and the outer side of the cable core is fitted on the inner side of the limiting grooves.

[0011] Preferably, anti-slip grooves are evenly arranged on the outer side of the waterproof membrane along the circumferential direction.

[0012] Preferably, the outer anti-slip mechanism includes a braided mesh layer and outer tensile steel wires. The braided mesh layer is located between the shielding layer and the outer sheath layer. The outer tensile steel wires are evenly spirally wound on the outer side of the braided mesh layer. The intersection of the outer tensile steel wires passes through the inside of the braided mesh layer.

[0013] Preferably, the inner anti-slip mechanism includes a mesh cloth and magnesium carbonate powder, the mesh cloth is located between the waterproof membrane and the shielding layer, the magnesium carbonate powder is filled in the mesh holes of the mesh cloth, and the magnesium carbonate powder is adhered to the shielding layer and the waterproof membrane.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model increases the tensile strength of the cable through the internal tensile steel wire between the cables and the tensile filling rope on the outside of the cable, and increases the friction between the internal layers of the cable through the external anti-slip mechanism composed of the woven mesh layer and the external tensile steel wire and the internal anti-slip mechanism composed of the mesh cloth and magnesium carbonate powder, ensuring that relative sliding will not occur when subjected to tension. The layers of the cable restrain each other, further improving the tensile strength.

[0016] 2. The utility model increases the stability of the outer anti-slip mechanism and the anti-slip stability of the outer sheath layer by spirally winding multiple groups of outer tensile steel wires on the outside of the braided mesh layer, and the intersection of the outer tensile steel wires passes through the inside of the braided mesh layer.

[0033] Example 1

[0034] like Figure 1 、 Figure 2 and Figure 3 As shown, this embodiment proposes a high-strength tensile-resistant shipboard cable structure, including a cable core 1, a waterproof membrane 3 wrapped on the outside of the cable core 1, a shielding layer 5 wrapped on the outside of the waterproof membrane 3, and an outer sheath layer 6 on the outside of the shielding layer 5. The cable cores 1 are evenly distributed in a circular array inside the waterproof membrane 3, an inner tensile steel wire 2 is arranged at the middle position of the cable core 1, a tensile filling rope 4 is filled between the outside of the cable core 1 and the waterproof membrane 3, an inner anti-slip mechanism 8 is provided between the outside of the waterproof membrane 3 and the shielding layer 5, and an outer anti-slip mechanism 7 is provided between the outside of the shielding layer 5 and the outer sheath layer 6.

[0035] When the cable is in use, the inner tensile steel wire 2 and the tensile filling rope 4 are used to increase the overall tensile strength. When the outside of the cable is pulled, the external force will be directly applied to the outer sheath layer 6. Due to the presence of the external anti-slip mechanism 7, a greater friction resistance is ensured between the outer sheath layer 6 and the shielding layer 5, and the connection is more stable. The use of the internal anti-slip mechanism 8 between the shielding layer 5 and the waterproof membrane 3 increases the friction resistance between the shielding layer 5 and the waterproof membrane 3 to ensure that the layers of the cable are stably connected to each other during the pulling process, thereby ensuring that the cable has a higher tensile strength.

[0036] Example 2

[0037] The solution in Example 1 is further introduced below in conjunction with a specific working method, as described below:

[0038] like Figure 1 As shown, as a preferred embodiment, on the basis of the above method, further, the outer side of the inner tensile steel wire 2 is evenly provided with a limiting groove 201 along the circumferential direction, and the outer side of the cable core 1 is attached to the inner side of the limiting groove 201.

[0039] The provision of the limiting groove 201 increases the contact area between the inner tensile steel wire 2 and the outer side of the cable core 1 , thereby improving the stability of the cable core 1 .

[0040] like Figure 1 As shown in FIG, as a preferred embodiment, on the basis of the above-mentioned embodiment, further, the outer side of the waterproof membrane 3 is evenly provided with anti-slip grooves 301 along the circumferential direction.

[0041] By providing the anti-skid groove 301 , the contact area between the waterproof membrane 3 and the inner anti-skid mechanism 8 is increased, thereby ensuring mutual stability during connection.

[0042] like Figure 1 and Figure 2As shown, as a preferred embodiment, on the basis of the above method, the external anti-slip mechanism 7 further includes a woven mesh layer 701 and an external tensile steel wire 702, the woven mesh layer 701 is located between the shielding layer 5 and the outer sheath layer 6, and the outer side of the woven mesh layer 701 is evenly spirally wound with the external tensile steel wire 702, and the intersection of the external tensile steel wire 702 passes through the inside of the woven mesh layer 701.

[0043] The outer sheath layer 6 is covered on the outside of the braided mesh layer 701 and the outer tensile steel wire 702, and has a large contact area. The outer tensile steel wire 702 will be connected to the outer sheath layer 6 during the covering process of the outer sheath layer 6, and the inner side of the braided mesh layer 701 is in contact with the shielding layer 5. The inner side of the braided mesh layer 701 is not smooth, so there is a large friction resistance between it and the shielding layer 5.

[0044] like Figure 1 and Figure 3 As shown, as a preferred embodiment, on the basis of the above method, the internal anti-slip mechanism 8 further includes a mesh cloth 801 and magnesium carbonate powder 802, the mesh cloth 801 is located between the waterproof membrane 3 and the shielding layer 5, the magnesium carbonate powder 802 is filled in the mesh holes on the mesh cloth 801, and the magnesium carbonate powder 802 is bonded to the shielding layer 5 and the waterproof membrane 3.

[0045] The presence of the mesh cloth 801 can limit the magnesium carbonate powder 802. The high anti-slip property of the magnesium carbonate powder 802 is used to increase the connection stability between the shielding layer 5 and the waterproof membrane 3. In addition, the magnesium carbonate powder 802 can also absorb water to keep the inside of the cable dry, further improving the friction.

[0046] Example 3

[0047] The solutions in Example 1 and Example 2 are further introduced below in conjunction with specific working methods, as described below:

[0048] When the cable is in use, the inner tensile steel wire 2 and the tensile filling rope 4 are used to increase the overall tensile strength. When the outside of the cable is pulled, the external force will be directly applied to the outer sheath layer 6. The outer sheath layer 6 is covered on the outside of the braided mesh layer 701 and the outer tensile steel wire 702, and has a large contact area. The outer tensile steel wire 702 will be connected to the outer sheath layer 6 during the covering process of the outer sheath layer 6, and the inner side of the braided mesh layer 701 is in contact with the shielding layer 5. The inner side of the braided mesh layer 701 is not smooth, so there is a large friction resistance between the shielding layer 5. In addition, the presence of the mesh cloth 801 limits the magnesium carbonate powder 802, and the high anti-slip property of the magnesium carbonate powder 802 is used to increase the connection stability between the shielding layer 5 and the waterproof membrane 3. In addition, the magnesium carbonate powder 802 can also absorb water to keep the inside of the cable dry, further improving the friction. The layers of the cable are stably connected to each other to ensure that the cable has a high tensile strength.

[0049] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present invention within the scope disclosed by the present invention, which falls within the protection scope of the present invention.
