Description
Technical Field
[0001] The present application relates to the technical field of cables, and in particular to a seawater corrosion-resistant and water-blocking cable. Background Art
[0002] With the progress of the times, the demand for the use of cables is not only in the sky and underground environments, but also in the sea. Cables used in the sea need to have water-blocking and corrosion-resistant capabilities.
[0003] Some of the cables used in seawater environments are laid on the seabed, such as transoceanic communication cables connecting continents and offshore wind power projects, and some are extended from the sea surface to the seabed, such as the floating umbilical cable used for remote control of underwater robots (ROVs). It needs to connect the underwater robot to the control equipment or mother ship on the water surface to provide power and transmit signals to the underwater robot.
[0004] Since the underwater robot needs to move flexibly underwater within a certain range, the weight of the umbilical cable still drags the underwater robot in the sea water, which has the defect of limiting the flexibility of the underwater robot's movement. Summary of the invention
[0005] In order to reduce the restrictions on the mobility of underwater robots, the present application provides a seawater corrosion-resistant water-blocking cable.
[0006] The present application provides a seawater corrosion resistant water blocking cable adopting the following technical solution: A seawater corrosion-resistant water-blocking cable comprises a cable core, a waterproof layer wrapped around the outside of the cable core, and a corrosion-resistant layer wrapped around the outside of the waterproof layer. A cable wing is fixed on the outer wall of the corrosion-resistant layer. The cable wing is arranged along the length direction of the cable core. Two cable wings are provided and symmetrically distributed on both sides of the cable core. The two cable wings are distributed in the middle and upper area of the cross-section of the corrosion-resistant layer.
[0007] By adopting the above technical scheme, the seawater corrosion-resistant water-blocking cable is provided with two cable wings symmetrically distributed on both sides of the cable core and located in the middle and upper area of the cross section of the corrosion-resistant layer on the outer wall of the corrosion-resistant layer along the length direction of the cable core. The cable wings increase the contact area and drainage volume between the cable and the seawater, and according to the Archimedes principle, significantly increase the buoyancy of the cable, and reduce the dead weight of the cable in the seawater; at the same time, this layout makes the center of gravity of the cable in the seawater move downward, effectively preventing the cable from tipping over or rolling in the water, and making the cable more stable in posture and position when floating. Reducing the dead weight in the seawater and being able to stabilize its own floating posture reduces the negative impact of the underwater robot on the underwater robot when it moves, and improves the flexibility of the underwater robot when it moves. Moreover, the special shape of the cable wing can guide the flow, so that the seawater flows smoothly on the surface of the cable, reduces the direct impact force of the water flow on the cable, reduces the water flow resistance, reduces the wear and fatigue damage of the cable caused by the water flow, and can also disrupt the flow pattern of the water flow around the cable, reduce the phenomenon such as Karman vortex street, reduce the amplitude and frequency of the cable vibration induced by the water flow, and improve the reliability of the cable in the underwater environment. In addition, the unique cable wing structure makes the cable significantly different from ordinary cables in appearance, making it easier to identify and locate in complex seawater environments, facilitating construction, installation and subsequent maintenance and inspection. The cable wing can also be used as an installation fulcrum to improve installation convenience.
[0008] Optionally, a cavity is provided in the waterproof layer, and the cavity is located above the connection line of the two cable wings.
[0009] By adopting the above technical solution, the cavity further increases the buoyancy of the cable, making the cable's floating state in the seawater more stable. At the same time, because the cavity is located above the cable wing connection line, it can help adjust the cable's center of gravity to a certain extent, allowing the cable to maintain a better posture under the impact of water flow, reducing the position deviation caused by water flow, thereby better ensuring the flexible movement of the underwater robot, and can also enhance the cable's water-blocking performance to a certain extent, preventing seawater from penetrating into the cable core.
[0010] Optionally, it also includes a protective shell that is slidably arranged along the length direction of the cable core, the protective shell is ring-circled on the outside of the corrosion-resistant layer and the cable wing, and there are multiple protective shells, and adjacent protective shells are spaced apart along the length direction of the cable core; the protective shell is composed of a plurality of adjusting sleeves, the interior of the adjusting sleeves is hollow, and adjacent adjusting sleeves are clamped and connected at the head and tail, and the inner wall of the adjusting sleeve is in sliding contact with the outer wall of the corrosion-resistant layer and the outer wall of the cable wing; a positioning strip for adjusting the position limit of the sleeve is provided on the cable wing.
[0011] By adopting the above technical solution, the protective shell can effectively protect the corrosion-resistant layer and the cable wings from collision and scratches by external objects, thereby extending the service life of the cable. The protective shell is hollow inside, which can enhance the buoyancy of the cable, and different numbers of adjustment sleeves can be assembled at will to adjust the buoyancy of the cable brought by the protective shell. Multiple protective shells are arranged at intervals to ensure the protective effect without excessively increasing the weight of the cable and affecting the movement of the underwater robot. At the same time, the protective shells at different positions of the cable provide different buoyancy, so as to adjust the overall posture of the cable and reduce the drag on the underwater robot when it moves. The positioning bar limits the position of the adjustment sleeve to prevent it from sliding at will, thereby ensuring the stability and reliability of the protective shell.
[0012] Optionally, an adjusting half ring is rotatably provided on the outer wall of the adjusting sleeve, and a through hole is provided on the adjusting half ring; a water inlet hole and a water outlet hole are provided on the adjusting sleeve, and rotating the adjusting half ring is used to control the opening and closing of the water inlet hole and the water outlet hole.
[0013] By adopting the above technical solution, the opening and closing of the water inlet and outlet holes are controlled by rotating the adjustment half ring, so as to adjust the water volume inside the protective shell, thereby adjusting the buoyancy generated by the protective shell on the cable, thereby achieving the effect of adjusting the entire posture of the cable, so that the entire path of the cable from the underwater robot to the equipment on the water surface is in a gradually rising suspension state, and there is not too much cable sinking to the seabed or floating on the water surface, thereby reducing the drag force on the underwater robot, thereby better cooperating with the flexible movement of the underwater robot.
[0014] Optionally, an annular groove is provided on the outer wall of the adjusting sleeve, and the annular groove is provided around the outer wall of the adjusting sleeve. The adjusting semi-ring is slidably arranged in the annular groove, and the water inlet hole and the water outlet hole are both located in the annular groove and symmetrically distributed on both sides of the cable core; the length of the adjusting semi-ring is 1 / 2 to 3 / 4 of the circumference of the adjusting sleeve, and the through hole is located at the midpoint of the length of the adjusting semi-ring itself; the middle part and both ends of the adjusting semi-ring itself are made of magnetically adsorbable material, and a magnet is embedded and fixed on the annular groove, and the magnet is located at the midpoint of the line connecting the water inlet hole and the water outlet hole along the inner wall of the annular groove.
[0015] By adopting the above technical solution, the sliding connection design of the ring groove and the adjusting half ring makes the rotation of the adjusting half ring smoother, which is convenient for controlling the opening and closing of the water inlet and outlet holes. The magnetic adsorbable material of the adjusting half ring cooperates with the magnet, and can automatically adsorb and fix the adjusting half ring when it rotates to a specific position, ensuring that the opening or closing state of the water inlet and outlet holes is stable, without the need for additional fixing devices, simplifying the structure, and improving the convenience and reliability of operation. When both the water inlet and outlet holes are open, that is, when the through hole coincides with the water inlet or outlet hole.
[0016] Optionally, a storage groove is provided on the cable wing, the storage groove is provided in a direction close to or away from the cable core, a plurality of storage grooves are provided, and adjacent storage grooves are provided at intervals along the length direction of the cable core; the number of positioning strips corresponds to the number of storage grooves, the positioning strips are hidden in the storage grooves, one end of the positioning strips is fixedly connected to the groove wall of the storage groove close to the cable core, and the positioning strips are plastic.
[0017] By adopting the above technical solution, the storage slot can hide the positioning strip when the positioning strip is not needed to reduce water flow resistance. When the position of the sleeve needs to be limited and adjusted, the plastic positioning strip can be taken out of the storage slot and bent to a suitable position. The operation is convenient and flexible, and the use state of the positioning strip can be adjusted according to actual conditions.
[0018] Optionally, a protrusion is fixed on the cable wing, and the protrusion is located on the groove wall of the storage groove and is used to limit the positioning bar from falling back into the storage groove when the positioning bar bends upward; there is a distance between the protrusion and the groove bottom of the storage groove.
[0019] By adopting the above technical solution, the protrusion can effectively prevent the positioning strip from accidentally falling back into the storage slot when limiting the position of the adjustment sleeve, ensuring that the positioning strip has a stable and reliable positioning effect. The distance between the protrusion and the bottom of the storage slot provides space for the positioning strip to be completely stored in the storage slot. The positioning strip passes through the gap between the protrusion and the bottom of the storage slot. At this time, the protrusion has a squeezing effect on the positioning strip, ensuring that the positioning strip can be stably stored in the storage slot.
[0020] Optionally, a first clamping strip is fixed on the vertical side wall on one side of the adjusting sleeve itself, and a second clamping strip is fixed on the vertical side wall on the other side, the first clamping strip first extends horizontally in the direction away from the adjusting sleeve and then extends downward, the second clamping strip first extends horizontally in the direction away from the adjusting sleeve and then extends upward, and an elastic pad is fixed on the inner wall of the first clamping strip; when adjacent adjusting sleeves are clamped and connected, the first clamping strip and the second clamping strip that are close to each other are clamped with each other.
[0021] By adopting the above technical solution, the special structural design of the first clamping strip and the second clamping strip makes the clamping connection of adjacent adjustment sleeves more stable and not easy to separate. The elastic pad can increase the friction during clamping, further improve the reliability of the connection, and also play a buffering role, reducing the looseness between the adjustment sleeves caused by collision or water flow impact, ensuring the overall structural stability of the protective shell, and better protecting the cable.
[0022] Optionally, a baffle plate for limiting the position of the second clamping strip is fixed on the first clamping strip, and when the end of the second clamping strip is engaged with the first clamping strip, the end of the second clamping strip abuts against the baffle plate at the same time.
[0023] By adopting the above technical solution, the baffle can accurately limit the locking position of the second locking strip, prevent the second locking strip from excessively rotating and missing the locking position with the first locking strip, and ensure the accuracy and stability of the locking connection.
[0024] Optionally, the cable wing is made of rubber material.
[0025] By adopting the above technical solution, the rubber material has good flexibility and corrosion resistance, can effectively adapt to the complex seawater environment, and is not easily damaged by seawater corrosion. At the same time, the flexibility of the rubber allows the cable wing to deform to a certain extent when it is impacted by water flow or external force collision, buffering the external force, reducing the impact on the internal structure of the cable, ensuring the normal use of the cable, and helping to maintain the floating stability of the cable in seawater, improving the mobility of the underwater robot.
[0026] In summary, the present application includes at least one of the following beneficial technical effects: Improve buoyancy and stability: The cavity in the waterproof layer and the hollow structure of the protective shell increase the buoyancy of the cable. Combined with the cable wings located in the middle and upper area of the corrosion-resistant layer section, it not only increases the drainage volume, but also assists in adjusting the center of gravity of the cable, making the cable float more stably in the seawater, reducing the position deviation caused by the water flow, ensuring the flexible movement of the underwater robot, and can adjust the buoyancy and stability by adjusting the water pressure in the protective shell according to needs, so as to better cooperate with the work of the underwater robot; Flexible adjustment and convenient operation: The adjusting sleeve can slide along the length of the cable core, and the protection position can be adjusted according to actual needs. The positioning strip can limit its position. The adjusting half ring rotates smoothly in the ring groove and is fixed by magnetic adsorption, so that the opening and closing of the water inlet and outlet holes can be conveniently controlled, and the buoyancy brought by the protective shell can be adjusted.
