Description

Technical Field

[0001] This invention relates to the field of cable technology, specifically to a tensile-resistant underwater cable. Background Technology

[0002] Cables are electrical devices used to transmit electrical energy or signals, and are widely used in power systems, communication systems, industrial automation and other fields.

[0003] Cables can be classified into various types according to their uses and structures, such as overhead cables, direct-buried cables, pipeline cables, and underwater cables. Among them, underwater cables have good waterproof performance and seawater corrosion resistance, and are often used for power and communication transmission across rivers and seas.

[0004] However, existing underwater cables can only withstand external tension through their own material properties. When the external tension is too great, they may crack. Such underwater cables have low tensile strength, and the electromagnetic field generated by the cable after it is energized on the seabed may be mistaken by sharks or other underwater creatures as signals from prey or their own kind, thus triggering biting behavior. Ultimately, this may cause the cable insulation layer to be penetrated, allowing current to flow into the seawater and causing cable failure. Therefore, these cables do not meet the current requirements. To address this, we propose a tensile-resistant underwater cable. Summary of the Invention

[0005] The purpose of this invention is to provide a tensile-resistant underwater cable to solve the problems mentioned in the background art, which are that existing underwater cables can only withstand external tension through their own material properties. When the external tension is too great, the cables may crack. Such underwater cables have low tensile strength, and the electromagnetic field generated by the cable after it is energized on the seabed may be mistaken by sharks or other underwater creatures as signals from prey or their own kind, thus triggering biting behavior.

A second spring is sleeved on the outer surface of the metal cones, and the surface of the second spring facing the semi-circular groove is in contact with the semi-circular groove.

[0009] A hollow arc-shaped connecting bridge is provided on one side of the metal cone. A plastic tube is fixedly connected to both ends of the hollow arc-shaped connecting bridge. An arc-shaped placement groove is provided on the outer side of the plastic tube on the outer surface of the rubber sleeve. The plastic tube is inserted into the interior of the arc-shaped placement groove. Both the hollow arc-shaped connecting bridge and the interior of the plastic tube contain fish repellent.

[0010] Preferably, the bottom end of the metal cone is provided with a tin plug, which is inserted into the mesh of the armored woven waterproof support sleeve.

[0011] Preferably, the connecting mechanism includes a rust-proof fixing sleeve, which is fixedly fitted onto the outer surface of the wave-shaped underwater cable core.

[0012] Preferably, the elastic stretching recovery mechanism includes two annular grooves, which are respectively located on the opposite surfaces of the two anti-bite cable outer protective shells that are attached to each other.

[0013] Preferably, a tension rubber sleeve is provided inside the two annular grooves. A strip groove is provided at the middle position of the upper and lower end faces of the tension rubber sleeve. A rubber rod is fixedly provided inside the strip groove. A first spring is sleeved on both sides of the outer surface of the rubber rod. One end of the first spring is connected to a rubber sleeve that is movably sleeved on the outer surface of the rubber rod. The surface of the rubber sleeve facing the inner wall of the annular groove is fixed to the inner wall of the annular groove.

[0014] Preferably, an outer protective sleeve is provided on the outer side of the plurality of hollow arc-shaped connecting bridges, and the surface of the hollow arc-shaped connecting bridge facing the outer protective sleeve is fixed to the outer protective sleeve.

[0015] Preferably, the inner wall of the outer protective sleeve is provided with an annular storage groove, and the metal cone, the second spring, the rubber sleeve, the plastic tube and the hollow arc-shaped connecting bridge are all located inside the annular storage groove, and the surface of the outer protective sleeve facing the armored woven waterproof support sleeve layer is fixed to the armored woven waterproof support sleeve layer.

[0016] Preferably, the outer protective shell of the anti-bite cable also includes two shaping partitions, the side of the shaping partition facing the wave-shaped underwater cable core is in contact with the wave-shaped underwater cable core, and the upper and lower end faces of the shaping partition are fixed to the inner wall of the armored braided waterproof support sleeve.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention features a wave-shaped underwater cable core located inside the outer protective shell of the anti-bite cable. Multiple anti-bite cable outer protective shells are connected by an elastic tension recovery mechanism. When the cable is subjected to external tension, the outer protective shells are separated, and the wave-shaped underwater cable core is gradually straightened, thus dispersing and buffering the tension. This technical solution reduces the external stress on the conductor and insulation layer inside the wave-shaped underwater cable core, eliminating the need for the cable to resist external tension through its own material properties. This reduces the risk of mechanical damage caused by tension, thereby improving the overall tensile strength and service life of the cable.

[0020] 2. This invention utilizes an anti-bite cable outer protective shell. When sharks or other large aquatic creatures bite the cable, the metal cone will penetrate the creature's mouth, causing pain and forcing it to release the cable. Simultaneously, before piercing the creature's mouth, the metal cone will first pierce a hollow, arc-shaped connecting bridge containing fish-repellent medication. Once the creature moves away from the cable, the medication will automatically flow out through the puncture, thus repelling the creature. This technical solution provides double protection for the cable, both physically and chemically, reducing the risk of cable penetration and the probability of shark bites, thereby extending the cable's lifespan.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Please see Figures 1 to 8 An embodiment of the present invention provides: a tensile underwater cable, including a seabed surface 25, a high tensile cable 1 above the seabed surface 25, the high tensile cable 1 including a corrugated underwater cable core 101, multiple anti-bite cable outer layer connecting protective shells 102, multiple elastic tensile recovery mechanisms and multiple connecting mechanisms, the corrugated underwater cable core 101 is corrugated in the whole;

[0032] Multiple anti-bite cable outer layer connecting protective shells 102 are located outside the wave-shaped underwater cable core 101 and are attached to each other. The wave-shaped underwater cable core 101 located inside the anti-bite cable outer layer connecting protective shell 102 is fixed to the anti-bite cable outer layer connecting protective shell 102 through a connecting mechanism. The elastic tension recovery mechanism can restore the anti-bite cable outer layer connecting protective shells 102 that have been separated due to external force to a state of mutual attachment.

[0033] The connecting mechanism includes a rust-proof fixing sleeve 103, which is fixedly fitted onto the outer surface of the wave-shaped underwater cable core 101. A rust-proof fixing connecting rod 104 is fixedly installed at the middle position of both the upper and lower end faces of the rust-proof fixing sleeve 103, and the other end of the rust-proof fixing connecting rod 104 is fixed to the inner wall of the anti-bite cable outer layer connecting protective shell 102. The rust-proof fixing sleeve 103 and the rust-proof fixing connecting rod 104 can fix the wave-shaped underwater cable core 101 to the anti-bite cable outer layer connecting protective shell 102, thereby ensuring the force balance between the wave-shaped underwater cable core 101 and the anti-bite cable outer layer connecting protective shell 102 and preventing the wave-shaped underwater cable core 101 from getting tangled together due to repeated stretching.

[0034] The elastic stretching and recovery mechanism includes two annular grooves 105, which are located on opposite sides of two anti-bite cable outer layer connecting protective shells 102 that are attached to each other. A stretching rubber sleeve 106 is provided inside each of the two annular grooves 105. A strip groove 107 is provided at the middle of the upper and lower ends of each stretching rubber sleeve 106. A rubber rod 108 is fixed inside the strip groove 107. A first spring 109 is fitted on both sides of the outer surface of the rubber rod 108. One end of the first spring 109 is connected to a rubber sleeve 110 that is movably fitted on the outer surface of the rubber rod 108. The surface of the rubber sleeve 110 facing the inner wall of the annular groove 105 is fixed to the inner wall of the annular groove 105. When the outer surface of the high-strength cable 1 is subjected to an external stretching force, the anti-bite cable outer layer connecting protective shells 102 that are attached to each other will gradually separate. During the movement of the anti-bite cable outer layer connecting protective shell 102, the rubber sleeve 110 fixed to it will move along with it and compress the first spring 109 connected to it.

[0035] As the outer protective shells 102 of the multiple anti-bite cables separate, the corrugated underwater cable cores 101 connected to them by multiple connecting mechanisms will be gradually straightened, thereby dispersing and buffering the tensile force. The above technical solution can reduce the external stress on the conductors and insulation layers inside the corrugated underwater cable cores 101, so that they no longer need to resist the external tensile force through their own material properties, thereby reducing the possibility of mechanical damage to the cable caused by tension, and thus improving the overall tensile performance and service life of the cable.

[0036] When the external tensile force disappears, the reaction force of the compressed first spring 109 can push the separated anti-bite cable outer layer connecting protective shell 102 back to its original position, thereby making the anti-bite cable outer layer connecting protective shell 102 stick together again.

[0037] The anti-bite cable outer protective shell 102 includes an armored braided waterproof support sleeve 2. The outer side of the armored braided waterproof support sleeve 2 is provided with a hollow partition 17. The outer side of the hollow partition 17 is provided with a rubber sleeve 5. The inner wall of the rubber sleeve 5 is provided with multiple semi-circular grooves 6. Each semi-circular groove 6 has a metal cone receiving groove 7 on its inner wall. Multiple metal cones 3 are uniformly fixed on the outer surface of the armored braided waterproof support sleeve 2, and the metal cones 3 are inserted into the interior of the metal cone receiving groove 7. A second spring 4 is sleeved on the outer surface of the metal cone 3, and the surface of the second spring 4 facing the semi-circular groove 6 is in contact with the semi-circular groove 6.

[0038] The bottom end of the metal cone 3 is provided with a tin plug 19, which is inserted into the mesh of the armored braided waterproof support sleeve 2.

[0039] The method for fixing the metal cone 3 to the surface of the armored braided waterproof support sleeve 2 includes the following steps:

[0040] When the armor braided waterproof support sleeve 2 is braided, a mesh is reserved. Since the bottom end of the metal cone 3 is provided with a tin plug 19, the tin plug 19 of the metal cone 3 is inserted into the mesh of the armor braided waterproof support sleeve 2. Then, a heating device is used to heat the plug point of the metal cone 3, so that the tin plug 19 melts and strengthens the connection with the armor braided waterproof support sleeve 2.

[0041] This welding process can be fully automated using an industrial robotic arm, thereby improving production efficiency when manufacturing this cable.

[0042] When it is necessary to braid the cable, the armored braided waterproof support sleeve 2 with metal cone 3 fixed on the curved outer surface is transformed into a tubular shape. It is fixed at the connection position on the tubular armored braided waterproof support sleeve 2 by welding. Finally, it is sleeved on the outer surface of the wave-shaped underwater cable core 101, and rubber sleeve 5 and outer protective sleeve 12 are sleeved on its outer surface one by one.

[0043] A hollow arc-shaped connecting bridge 10 is provided on one side of the metal cone 3. A plastic tube 9 is fixedly connected to both ends of the hollow arc-shaped connecting bridge 10. An arc-shaped placement groove 8 is provided on the outer side of the plastic tube 9 on the outer surface of the rubber sleeve 5. The plastic tube 9 is inserted into the interior of the arc-shaped placement groove 8. Both the hollow arc-shaped connecting bridge 10 and the interior of the plastic tube 9 contain fish repellent 11.

[0044] An outer protective sleeve 12 is provided on the outer side of multiple hollow arc-shaped connecting bridges 10, and the surface of the hollow arc-shaped connecting bridge 10 facing the outer protective sleeve 12 is fixed to the outer protective sleeve 12; the inner wall of the outer protective sleeve 12 is provided with an annular receiving groove 18, and the metal cone 3, the second spring 4, the rubber sleeve 5, the plastic tube 9 and the hollow arc-shaped connecting bridge 10 are all located inside the annular receiving groove 18, and the surface of the outer protective sleeve 12 facing the armored braided waterproof support sleeve 2 is fixed to the armored braided waterproof support sleeve 2; the outer protective sleeve 12 can fix the metal cone 3, the second spring 4, the rubber sleeve 5, the plastic tube 9 and the hollow arc-shaped connecting bridge 10, preventing them from being misaligned due to the external environment, and the outermost outer protective sleeve 12 can form the initial protective layer;

[0045] Multiple second springs 4, fitted onto the outer surface of the metal cone 3 and connected to the inner wall of the semi-circular groove 6, can support the rubber sleeve 5, thereby forming a hollow partition 17 between the rubber sleeve 5 and the armored braided waterproof support layer 2. When a shark or other large aquatic creature bites the cable, the spring force of the second springs 4 causes the cable to undergo a certain elastic deformation when bitten by the shark. This deformation can disperse the shark's biting force, reduce the direct impact on the outer rubber shell of the cable, and thus reduce the risk of being bitten. The above technical solution improves the anti-biting strength of the equipment.

[0046] The hollow partition 17 supported by the second spring 4 provides the cable with a deformation space, which allows the metal cone 3 to be housed inside the cable. With the above technical solution, it is not necessary to fix the metal cone 3 to the outer surface of the cable in order to ensure that the metal cone 3 can function, so that there is no need to worry about being punctured by the metal cone 3 during the cable laying process.

[0047] When the outer protective sleeve 12 and rubber sleeve 5 located on the outside of the cable are deformed due to the biting of sharks or large aquatic creatures, the distance between the deformed position on the outer protective sleeve 12 and rubber sleeve 5 and the armored braided waterproof support sleeve 2 will gradually decrease, compressing the second spring 4. As the distance between the two decreases, the metal cone 3 fixed to the outer surface of the armored braided waterproof support sleeve 2 will pass through the metal cone receiving groove 7 located on the outer surface of the rubber sleeve 5 and pierce the outer protective sleeve 12, eventually piercing into the mouth of the aquatic creature, causing pain. This will ultimately drive away the aquatic creature and prevent it from continuing to bite the cable. The above technical solution can prevent the aquatic creature from continuing to bite the cable and causing further damage to the cable.

[0048] When the metal cone 3 passes through the metal cone receiving groove 7, it will first pierce the corresponding hollow arc-shaped connecting bridge 10. When the aquatic creatures feel pain and flee from around the cable, ceasing to bite it, the reaction force of the compressed second spring 4 can restore the rubber sleeve 5 and the outer protective sleeve 12, which were deformed due to the bites of the aquatic creatures, to their original shape. After the deformed parts of the rubber sleeve 5 and the outer protective sleeve 12, which were deformed due to the bites of the aquatic creatures, are restored to their original shape, the fish repellent 11 inside the hollow arc-shaped connecting bridge 10 will flow out from the piercing point of the metal cone 3. By releasing the fish repellent 11, the aquatic creatures around the cable can be dispersed, thereby preventing other aquatic creatures from biting the cable in a short period of time. Through the above technical solution, sharks can be further dispersed, thereby reducing the number of times the cable is bitten by aquatic creatures.

[0049] The anti-bite cable outer protective shell 102 also includes two shaping partitions 13. The surface of the shaping partitions 13 facing the wave-shaped underwater cable core 101 is in contact with the wave-shaped underwater cable core 101, and the upper and lower end faces of the shaping partitions 13 are fixed to the inner wall of the armored braided waterproof support sleeve 2. A first support tube placement platform 14 is fixedly provided on the surface of the shaping partitions 13 facing the inner wall of the armored braided waterproof support sleeve 2, and the inner wall of the armored braided waterproof support sleeve 2 corresponds to the first support tube placement platform 14. A second support tube placement platform 15 is fixedly provided in a position. A support tube 16 is provided between the first support tube placement platform 14 and the second support tube placement platform 15. The support tube 16 is made of high elastic rubber in one piece. The shaping partition 13 fixed on the inner wall of the armored braided waterproof support sleeve 2 can reduce the space available for the deformation of the wave-shaped underwater cable core 101, thereby further preventing the wave-shaped underwater cable core 101 from getting tangled due to repeated bending and deformation.

[0050] The support tube 16 can support the shaping partition 13, and the support of the support tube 16 can further improve the elasticity of both sides of the cable, thereby further improving the anti-seize strength of both sides of the cable.

[0051] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
