Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a waterproof reinforced cable for marine use in oil exploration. Background Technology

[0002] Submarine cables are cables wrapped in insulating materials and laid on the seabed for telecommunications transmission. Submarine cables are divided into submarine communication cables and submarine power cables. Modern submarine cables use optical fibers as materials to transmit telephone and internet signals. Since the optical fibers are damaged, the cable needs to be protected by multiple layers of optical fibers.

[0003] The existing patent CN203573730U, entitled "A Waterproof Reinforced Special Communication Cable for Marine Use in Oil Exploration," proposes that this utility model enhances the stability of cable signal transmission by uniformly twisting seven strands of oxygen-free copper wire together, increases the overall tensile strength of the cable by setting an aramid braided reinforcement layer between the polyurethane inner sheath and the polyurethane outer sheath, enhances the waterproof performance of the cable by filling the space between the polyurethane inner sheath and the insulated core, and enhances the heat resistance, abrasion resistance, and tensile strength of the cable by the polyurethane inner and outer sheaths.

[0004] When installing and limiting the cable, a clamp is needed to be placed on the cable, and then the two ends of the clamp are fixed to the seabed with screws. This makes the limiting part of the cable more susceptible to squeezing and wear by the clamp compared to other parts. Therefore, it is necessary to propose a waterproof and reinforced marine cable for oil exploration to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a waterproof reinforced cable for marine oil exploration, in order to solve the problem mentioned above that when installing and limiting the existing waterproof reinforced cable for marine oil exploration, a clamp needs to be placed on the cable and then the two ends of the clamp are fixedly connected to the seabed with screws, making the limiting part of the cable more susceptible to clamp compression and wear than other parts.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waterproof reinforced cable for marine use in oil exploration, comprising a cable body and a protective sleeve fixedly wrapped around the outer ring of the cable body. The anti-slip sleeve consists of, from the outside to the inside, a wear-resistant layer, a first inner armor steel wire, an adhesive layer, and a waterproof elastic sealant layer. The outer ring of the wear-resistant layer is provided with anti-slip texture. The outside of the first inner armor steel wire and located between the wear-resistant layer and the adhesive layer is filled with asphalt. The waterproof elastic sealant layer is fixedly connected to the outer ring of the cable body.

[0007] The cable body, from the outside to the inside, consists of a polyurethane outer sheath, an aramid braided reinforcement layer, a polypropylene rope, an outer armor steel wire, a polyethylene insulation layer, a copper tube, a second inner armor steel wire, a stainless steel tube, and an optical fiber.

[0008] Preferably, fiber grease is filled between the stainless steel tube and the optical fiber.

[0009] Preferably, a reflective layer is spirally wound around the outer ring of the cable body.

[0010] Preferably, the polypropylene rope and the outer armor steel wire are wrapped with bitumen 2, and the bitumen 2 is located between the polyethylene insulation layer and the aramid fiber braided reinforcement layer.

[0011] Preferably, the space between the copper tube and the stainless steel tube is filled with a water-blocking adhesive wrapped around the outside of the second inner armor steel wire.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model provides a protective sleeve fixedly fitted on the outer ring of the cable body. By installing the protective sleeve, the installation part of the cable body is protected from direct contact between the clamp and the cable body when it is fixed with a clamp, thereby protecting the installation part of the cable body. This solves the problem that existing marine waterproof reinforced cables for oil exploration require clamps to be fitted on the cable and screws to fix the two ends of the clamps to the seabed when installing and limiting the cable, making the limiting part of the cable more susceptible to clamp compression and wear than other parts.

[0014] 2. When seawater or foreign objects touch and cause the cable body to swing, the waterproof elastic sealant layer can absorb some of the kinetic energy of that part, reduce the displacement of that part, thereby preventing the clamps and screws from loosening and improving the limiting stability of the cable body.

[0015] 3. The first protective line of the optical fiber is formed by setting up a polyurethane outer sheath, an aramid fiber braided reinforcement layer, a polypropylene rope, an outer armor steel wire, and a polyethylene insulation layer. The second protective line is formed by installing a copper tube, a second inner armor steel wire, and a stainless steel tube, which provides a second layer of close-range protection for the fragile optical fiber inside the stainless steel tube. As a result, this optical fiber can be installed on the seabed at depths of 1 meter or more, enhancing the performance of the optical fiber.

[0016] 4. By applying asphalt one, the tightness between the first inner armor steel wire, the wear-resistant layer, and the adhesive layer is improved, thereby enhancing the overall toughness of the anti-slip sleeve. By applying asphalt two, the polypropylene rope and the outer armor steel wire are integrated, filling the gaps while improving the overall toughness of the cable body. In addition, asphalt two fixes the polyethylene insulation layer and the aramid fiber braided reinforcement layer, strengthening the overall integrity of the cable body. Attached Figure Description

[0022] 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.

[0023] This utility model provides, for example Figures 1-4 The illustrated marine waterproof reinforced cable for oil exploration includes a cable body 1. Considering that when installing and limiting the cable, a clamp needs to be fitted onto the cable, and then the two ends of the clamp are fixedly connected to the seabed with screws, the limiting part of the cable is more susceptible to squeezing and wear by the clamp compared to other parts. Therefore, this utility model provides a protective sleeve 2 fixedly fitted on the outer ring of the cable body 1. By installing the protective sleeve 2, the clamp will not directly contact the cable body 1 when the installation part of the cable body 1 is fixed with the clamp, thereby protecting the installation part of the cable body 1.

[0024] Specifically, the anti-slip sleeve 2 consists of, from the outside to the inside, a wear-resistant layer 3, a first inner armor steel wire 4, an adhesive layer 5, and a waterproof elastic putty layer 6. The waterproof elastic putty layer 6 is fixedly connected to the outer ring of the cable body 1, and the outer ring of the wear-resistant layer 3 is provided with anti-slip texture.

[0025] By installing the wear-resistant layer 3, when seawater or foreign objects touch and cause the cable body 1 to swing, the wear between the anti-slip sleeve 2 and the clamp is reduced, and the inside of the anti-slip sleeve 2 will not be damaged, thereby protecting the performance of the relevant protective layers inside the anti-slip sleeve 2. By installing the first inner armor steel wire 4, it can resist part of the pressure of the clamp, avoid the pressure of the clamp being directly applied to the cable body 1, protect the installation part of the cable body 1 from being deformed by pressure, and improve the tensile strength and torque of the anti-slip sleeve 2.

[0026] In addition, considering that the installation part of the cable body 1 is relatively weak, it is necessary to strengthen the waterproof protection. By installing the waterproof elastic sealant layer 6, the waterproof measures can be further strengthened at this point. Moreover, the waterproof elastic sealant layer 6 has a certain degree of elasticity, thereby avoiding direct rigid contact between the first inner armor steel wire 4 and the cable body 1.

[0027] Meanwhile, when seawater or foreign objects touch and cause the cable body 1 to swing, the waterproof elastic sealant layer 6 can absorb some of the kinetic energy of that part, reduce the displacement of that part, thereby preventing the clamps and screws from loosening and improving the limiting stability of the cable body 1.

[0028] By installing the adhesive layer 5, the first inner armor steel wire 4 is firmly installed on the outer ring of the waterproof elastic sealant layer 6, preventing the first inner armor steel wire 4 from shifting or even falling off when the cable body 1 swings.

[0029] Furthermore, asphalt is filled on the outside of the first inner armor steel wire 4 and between the wear-resistant layer 3 and the adhesive layer 5. The asphalt binds the first inner armor steel wire 4, the wear-resistant layer 3 and the adhesive layer 5 together, improving the tightness between the first inner armor steel wire 4, the wear-resistant layer 3 and the adhesive layer 5, and improving the overall toughness of the anti-slip sleeve 2.

[0030] Furthermore, the cable body 1 consists of, from the outside to the inside, a polyurethane outer sheath 7, an aramid braided reinforcing layer 8, a polypropylene rope 9, an outer armor steel wire 10, a polyethylene insulation layer 11, a copper tube 12, a second inner armor steel wire 13, a stainless steel tube 14, and an optical fiber 15.

[0031] The first protective line for the optical fiber 15 is formed by the installation of a polyurethane outer sheath 7, an aramid fiber braided reinforcement layer 8, a polypropylene rope 9, an outer armor steel wire 10, and a polyethylene insulation layer 11. The second protective line is formed by the installation of a copper tube 12, a second inner armor steel wire 13, and a stainless steel tube 14, providing a second layer of close-range protection for the fragile optical fiber 15 inside the stainless steel tube 14. As a result, the optical fiber 15 can be installed on the seabed at depths of up to 1000 meters, enhancing its performance.

[0032] Specifically, the overall tensile strength of the cable body 1 is improved by setting the aramid fiber braided reinforcement layer 8. Considering that the cable body 1 needs to resist damage from hard and sharp rocks, anchors, and fishing boat trawls during the laying process, the wear resistance of the cable body 1 is improved by setting the polypropylene rope 9 and the outer armor steel wire 10.

[0033] Similar to asphalt, asphalt 2 is wrapped around the outside of the polypropylene rope 9 and the outer armor steel wire 10, and the asphalt 2 is located between the polyethylene insulation layer 11 and the aramid fiber braided reinforcement layer 8. By setting the asphalt 2, the polypropylene rope 9 and the outer armor steel wire 10 are integrated into one, filling the gaps and improving the overall toughness of the cable body 1. In addition, the asphalt 2 fixes the polyethylene insulation layer 11 and the aramid fiber braided reinforcement layer 8, strengthening the integrity of the cable body 1.

[0034] In order to fix the optical fiber 15 inside the stainless steel tube 14, fiber grease is filled between the stainless steel tube 14 and the optical fiber 15 to protect the stability of the optical fiber 15 and prevent it from directly contacting the stainless steel tube 14.

[0035] Furthermore, a reflective layer 16 is spirally wound around the outer ring of the cable body 1. The reflective layer 16 can reflect light, making it easier to locate the cable body 1.

[0036] Furthermore, a water-blocking adhesive wrapped around the second inner armor steel wire 13 is filled between the copper tube 12 and the stainless steel tube 14. The water-blocking adhesive prevents seawater from penetrating into the stainless steel tube 14, thereby improving the waterproof performance of the cable body 1.
