Abstract
Description
Technical Field
[0001] This utility model relates to the field of water pressure resistant cable technology, and in particular to an underwater high water pressure resistant cable. Background Technology
[0002] A cable is a conductor used to transmit electrical power or signals. It typically consists of multiple insulated conductors, encased in insulating material and a protective layer. Cables are widely used in construction, communications, and power transmission, effectively transmitting power or signals and protecting the conductors from external environmental influences. Common cable types include power cables, communication cables, and fiber optic cables. Prolonged immersion in water can damage cables, causing them to be bitten by fish, leading to leakage, short circuits, and ultimately, circuit failure.
[0003] Chinese utility model patent CN222672655U discloses an underwater high-pressure resistant cable, belonging to the field of cables. It includes a protective layer and a cable core, with a cable protection mechanism between the protective layer and the cable core. The cable protection mechanism includes a pressure-resistant layer fixedly installed inside the protective layer, with the cable core located inside the pressure-resistant layer. Tensile reinforcement strips are fixedly installed inside the protective layer, and an anti-bite layer is fixedly installed on the outer surface of the protective layer. A protective layer is fixedly installed on the outer surface of the anti-bite layer, and an anti-corrosion layer is fixedly installed on the outer surface of the protective layer. This underwater high-pressure resistant cable improves the overall tensile strength and lateral compressive strength of the cable by incorporating tensile reinforcement strips within the protective layer. The triangular cross-sectional pressure-resistant layer on the outer surface of the cable core improves the longitudinal compressive strength of the cable. The anti-bite layer on the outer surface of the protective layer prevents damage to the cable from fish or other aquatic organisms in the water.
[0004] Regarding the aforementioned technologies, the inventors believe the following drawbacks exist: The device protects the cable through an anti-bite layer placed outside the protective layer, and provides corrosion protection to the cable's surface through the protective layer and the anti-corrosion layer. When fish bite the cable, the anti-bite layer reduces the probability of damage to the cable core, but the anti-corrosion layer is easily damaged by fish bites. In actual use, to reduce corrosion of the protective layer, personnel need to regularly inspect the damage to the anti-corrosion layer. Since the cable is underwater, current methods mostly involve personnel carrying headlamps or other lighting equipment to closely observe the surface condition of the anti-corrosion layer. Because the surface of the anti-corrosion layer is cylindrical, this method is difficult to inspect and provides a poor user experience. Utility Model Content
[0005] To address the aforementioned problems, this utility model provides an underwater high-pressure resistant cable.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an underwater high-pressure resistant cable, comprising a conductor body, a pressure-resistant layer installed on the surface of the conductor body, a first filling layer jointly installed on the pressure-resistant layer and the conductor body, a second filling layer disposed on the side wall of the pressure-resistant layer, a protective layer disposed on the side wall of the second filling layer, and an anti-bite layer disposed on the side wall of the protective layer. The side wall of the anti-bite layer is provided with a protective layer, the side wall of the protective layer is provided with an anti-corrosion layer, and the protective layer is provided with a detection component for reducing the difficulty for workers to detect damage to the anti-corrosion layer.
[0007] By adopting the above technical solution, when the cable is underwater, the anti-bite layer blocks fish, thereby reducing the probability of damage to the main conductor, and the anti-corrosion layer protects the cable surface from corrosion. After a period of use, to extend the cable's lifespan, staff need to periodically inspect the anti-corrosion layer for damage. At this time, staff need to turn on ultraviolet lamps to continuously irradiate the surface of the anti-corrosion layer. If the anti-corrosion layer is damaged, the ultraviolet light can directly penetrate the protective layer and come into contact with the phosphor layer, thus reflecting fluorescence. Staff only need to observe whether a fluorescent reaction occurs on the surface of the anti-corrosion layer to judge its wear condition, thereby reducing the difficulty of cable maintenance.
[0008] Furthermore, the detection component includes an adhesive layer disposed on the inner wall of the protective layer, a phosphor layer disposed on the inner wall of the adhesive layer, a wear-resistant layer disposed on the side wall of the phosphor layer away from the adhesive layer, and an illumination device disposed on the anti-corrosion layer for illumination.
[0009] By adopting the above technical solution, when workers need to inspect the anti-corrosion layer, they only need to turn on the lighting device to allow ultraviolet light to continuously irradiate the surface of the anti-corrosion layer. If the anti-corrosion layer is intact, the ultraviolet light will diffusely reflect off the surface of the anti-corrosion layer, resulting in uniform light distribution. If the anti-corrosion layer is damaged, the ultraviolet light can directly penetrate the protective layer and come into contact with the phosphor layer, thus reflecting fluorescence. At this time, workers can observe the fluorescence reaction. Compared with diffuse reflection, the fluorescence reaction is more obvious in the dark underwater environment, thereby reducing the difficulty for workers to judge the wear and tear of the anti-corrosion layer. Furthermore, workers only need to repair the damaged parts of the anti-corrosion layer to complete the inspection, thus reducing the difficulty of cable inspection.
[0010] Furthermore, the lighting device includes a connecting ring slidably disposed on the anti-corrosion layer, a support rod fixedly disposed on the side wall of the connecting ring, a mounting ring fixed to the end of the support rod, a plurality of ultraviolet lamp beads evenly distributed on the inner wall of the mounting ring, a battery holder mounted on the side wall of the mounting ring, and a button battery disposed in the battery holder, wherein the plurality of ultraviolet lamp beads are electrically connected to the button battery and the battery holder.
[0011] By adopting the above technical solution, when workers need to inspect the anti-corrosion layer, they only need to connect the button battery and the battery holder on the water surface and reinstall the sealing gasket on the battery holder to waterproof the button battery, thus allowing the ultraviolet lamp to emit ultraviolet rays. Furthermore, workers only need to slide the connecting ring to move the ultraviolet lamp with the connecting ring, thereby reducing the difficulty of inspecting the cable.
[0012] Furthermore, multiple ball bearings are rotatably arranged on the inner wall of the connecting ring.
[0013] By adopting the above technical solution, the ball bearing reduces the difficulty for workers to move the connecting ring, thereby reducing the difficulty for workers to move the ultraviolet lamp beads and the installation ring, and thus improving the user experience for workers.
[0014] Furthermore, a plane mirror is fixed to the lower end of the side wall of the mounting ring.
[0015] By adopting the above technical solution, when multiple ultraviolet lamp beads emit ultraviolet light at the same time, the plane mirror can observe the bottom of the cable. The staff can carry out overall inspection of the surface of the anti-corrosion layer without adjusting their own position, thereby further reducing the difficulty of operation for the staff.
[0016] Furthermore, the support rod is equipped with a connecting rope to reduce the difficulty for workers to move the installation ring.
[0017] Furthermore, the end of the connecting rope is provided with a movable loop to reduce the difficulty for workers to move the connecting rope.
[0018] By adopting the above technical solution, when the staff needs to move the installation ring, they only need to pull the moving ring, and the installation ring will move with the moving ring under the action of the connecting rope, thereby reducing the difficulty of operation for the staff.
[0019] Furthermore, the conductor body includes a copper conductor, a shielding layer disposed on the surface of the copper conductor, and an insulating layer disposed on the sidewall of the shielding layer.
[0020] In summary, this utility model has the following beneficial effects:
[0021] 1. In this application, when the cable is underwater, the anti-bite layer blocks fish, thereby reducing the probability of damage to the main conductor, and the anti-corrosion layer protects the cable surface from corrosion. After a period of use, to extend the cable's service life, personnel need to periodically inspect the anti-corrosion layer for damage. At this time, personnel need to turn on ultraviolet lamps to continuously irradiate the surface of the anti-corrosion layer. If the anti-corrosion layer is damaged, the ultraviolet light can directly penetrate the protective layer and come into contact with the phosphor layer, thus reflecting fluorescence. At this point, personnel only need to observe whether a fluorescent reaction occurs on the surface of the anti-corrosion layer to judge the wear condition of the anti-corrosion layer, thereby reducing the difficulty of cable maintenance.
[0022] 2. In this application, when workers need to inspect the anti-corrosion layer, they need to turn on the lighting device to allow ultraviolet light to continuously irradiate the surface of the anti-corrosion layer. If the anti-corrosion layer is intact, the ultraviolet light will diffusely reflect off the surface of the anti-corrosion layer, resulting in uniform light distribution. If the anti-corrosion layer is damaged, the ultraviolet light can directly penetrate the protective layer and come into contact with the phosphor layer, thus reflecting fluorescence. At this time, workers can observe the fluorescence reaction. Compared with diffuse reflection, the fluorescence reaction is more obvious in the dark underwater environment, thereby reducing the difficulty for workers to judge the wear condition of the anti-corrosion layer. Furthermore, workers only need to repair the damaged parts of the anti-corrosion layer to complete the inspection, thereby reducing the difficulty for workers to inspect cables.
[0023] 3. In this application, when workers need to inspect the anti-corrosion layer, they need to connect the button battery and the battery holder on the water surface and reinstall the sealing gasket on the battery holder to waterproof the button battery, thereby allowing the ultraviolet lamp to emit ultraviolet light. Furthermore, workers only need to slide the connecting ring to move the ultraviolet lamp with the connecting ring, thus reducing the difficulty of inspecting the cable. Attached Figure Description

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0030] like Figure 1-4 As shown in the illustration, this application discloses an underwater high-pressure resistant cable, comprising a conductor body 1, a pressure-resistant layer 2, a first filling layer 21, a second filling layer 3, a protective layer 31, an anti-bite layer 4, a protective layer 41, an anti-corrosion layer 5, a detection component 6, a ball bearing 8, a plane mirror 81, a connecting rope 82, and a moving ring 9. The conductor body 1 includes a copper conductor 11, a shielding layer 12, and an insulation layer 13. The shielding layer 12 is disposed on the surface of the copper conductor 11, and the insulation layer 13 is disposed on the sidewall of the shielding layer 12.
[0031] A pressure-resistant layer 2 is installed on the surface of the conductor body 1. A first filling layer 21 is installed on both the pressure-resistant layer 2 and the conductor body 1 to improve the stability of the pressure-resistant layer 2. A second filling layer 3 is disposed on the side wall of the pressure-resistant layer 2, and a protective layer 31 is disposed on the side wall of the second filling layer 3. An anti-bite layer 4 is disposed on the side wall of the protective layer 31 and is made of wire mesh. A protective layer 41 is disposed on the side wall of the anti-bite layer 4, and an anti-corrosion layer 5 is disposed on the side wall of the protective layer 41.
[0032] The detection component 6 is disposed on the protective layer 41 to reduce the difficulty for workers to inspect for damage to the anti-corrosion layer 5. The detection component 6 includes an adhesive layer 61, a fluorescent powder layer 62, a wear-resistant layer 63, and an illumination device 7. The adhesive layer 61 is disposed on the inner wall of the protective layer 41, the fluorescent powder layer 62 is disposed on the inner wall of the adhesive layer 61, and the wear-resistant layer 63 is disposed on the side wall of the fluorescent powder layer 62 away from the adhesive layer 61.
[0033] When workers need to inspect the anti-corrosion layer 5, they need to turn on the lighting device 7 to allow ultraviolet light to continuously irradiate the surface of the anti-corrosion layer 5. If the anti-corrosion layer 5 is intact, the ultraviolet light will diffusely reflect off its surface, resulting in uniform light distribution. If the anti-corrosion layer 5 is damaged, the ultraviolet light can directly penetrate the protective layer 31 and come into contact with the phosphor layer 62, thus reflecting fluorescence. At this time, workers can observe the fluorescence reaction. Compared to diffuse reflection, the fluorescence reaction is more pronounced in the dark underwater environment, thus reducing the difficulty for workers to judge the wear condition of the anti-corrosion layer 5. Furthermore, workers only need to repair the damaged parts of the anti-corrosion layer 5 to complete the inspection, thereby reducing the difficulty of cable inspection.
[0034] A lighting device 7 is mounted on the anti-corrosion layer 5 for illumination. The lighting device 7 includes a connecting ring 71, a support rod 72, a mounting ring 73, ultraviolet lamp beads 74, a battery holder 75, and a button battery 76. The connecting ring 71 is a circular plate structure and is slidably mounted on the anti-corrosion layer 5. Two support rods 72 are symmetrically fixed to the side walls of the connecting ring 71. The mounting ring 73 is a circular plate structure and is mounted on the ends of the two support rods 72. Multiple ultraviolet lamp beads 74 are evenly distributed on the inner wall of the mounting ring 73, and the battery holder 75 is mounted on the side wall of the mounting ring 73. The button battery 76 is disposed within the battery holder 75, and the multiple ultraviolet lamp beads 74 are electrically connected to the button battery 76 and the battery holder 75.
[0035] When maintenance is required on the anti-corrosion layer 5, the worker needs to connect the button battery 76 to the battery holder 75 on the water surface and reinstall the sealing gasket on the battery holder 75 to waterproof the button battery 76, thus allowing the ultraviolet lamp bead 74 to emit ultraviolet rays. Furthermore, the worker only needs to slide the connecting ring 71 to move the ultraviolet lamp bead 74 along with the connecting ring 71, thereby reducing the difficulty of cable maintenance.
[0036] Multiple ball bearings 8 are provided and rolled on the inner wall of the connecting ring 71. The ball bearings 8 reduce the difficulty for the operator to move the connecting ring 71, thereby reducing the difficulty for the operator to move the ultraviolet lamp bead 74 and the mounting ring 73, and thus improving the operator's user experience.
[0037] Two plane mirrors 81 are symmetrically arranged on the lower side wall of the mounting ring 73. When multiple ultraviolet lamp beads 74 emit ultraviolet light at the same time, the plane mirrors 81 observe the lower part of the cable. The staff can carry out overall inspection of the surface of the anti-corrosion layer 5 without adjusting their own position, thereby further reducing the difficulty of operation for the staff.
[0038] One end of the connecting rope 82 is attached to the support rod 72 to reduce the difficulty for workers to move the installation ring 73. The moving ring 9 is a circular plate structure and is attached to the end of the connecting rope 82 to reduce the difficulty for workers to move the connecting rope 82.
[0039] When the staff needs to move the installation ring 73, they only need to pull the moving ring 9, and the installation ring 73 will move with the moving ring 9 under the action of the connecting rope 82, thereby reducing the difficulty of operation for the staff.
[0040] The operating principle of the underwater high-pressure resistant cable in this embodiment is as follows: When the cable is underwater, the anti-bite layer 4 blocks fish, thereby reducing the probability of damage to the conductor body 1, and the anti-corrosion layer 5 provides anti-corrosion protection for the cable surface. After a period of use, in order to extend the cable's service life, the staff needs to periodically inspect the damage to the anti-corrosion layer 5. At this time, the staff needs to turn on the ultraviolet lamp bead 74, so that ultraviolet rays can continuously irradiate the surface of the anti-corrosion layer 5. If the anti-corrosion layer 5 is damaged, the ultraviolet rays can directly penetrate the protective layer 31 and come into contact with the phosphor layer 62, thereby reflecting fluorescence. At this time, the staff only needs to observe whether the surface of the anti-corrosion layer 5 has a fluorescent reaction to judge the wear condition of the anti-corrosion layer 5, thereby reducing the difficulty of the staff to inspect the cable.
[0041] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected by this utility model. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
