Description

Technical Field

[0001] The present invention belongs to the technical field of cables, and particularly relates to a cable for a small offshore buoy, a preparation method thereof, and a cable laying and arranging device. Background Art

[0002] The ocean is the cradle of life and a valuable wealth for the sustainable development of human society. Currently, with the increasingly severe problems such as shortage of land resources, population explosion, and environmental deterioration, coastal countries have turned their attention to the ocean and accelerated the development and utilization of the ocean.

[0003] Due to the vast area of the sea, in harsh sea conditions, equipment such as ships is more likely to get lost. Therefore, it is necessary to set up buoy devices such as guiding buoys and communication buoys at sea.

[0004] Currently, the buoy cables on the market still have deficiencies in terms of resistance to ocean impact and tensile force. Moreover, after the cable storage barrel is put into the ocean, it is likely to cause environmental pollution, and the release operation is complex. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems of insufficient resistance to ocean impact and tensile force of the buoy cable, as well as the environmental pollution caused by the cable storage barrel and the complex release operation. The present invention provides a cable for a small offshore buoy, a preparation method thereof, and a cable storage and laying device. Among them, the cable storage and laying device includes a laying device and a cable storage barrel for storing and laying the cable. The laying device includes a laying chassis, a rotating chassis rotatably arranged in the middle of the laying chassis, and a laying central axis. The rotating chassis and the laying central axis are coaxially arranged. The cable is wound around the outer periphery of the laying central axis through the rotation of the rotating chassis, and the laying is completed by tying and binding wires;

[0006] The cable storage barrel includes a base, a cable storage shaft and a cable storage barrel body concentrically fixed on the upper surface of the base. The outer diameter of the cable storage shaft is less than or equal to the outer diameter of the laying central axis. After the laying is completed, the cable is tied into a whole by tying wires, taken out and inserted on the outer periphery of the cable storage shaft. After combining the cable storage barrel body, the tying wires are cut off, and the cable is completed for packaging and storage;

[0007] The cable storage barrel is made of a biodegradable paper material.

[0008] Furthermore, a plurality of rectangular holes are equidistantly arranged on the laying chassis. Each rectangular hole is provided with a liftable rectangular rod. The rectangular rod is detachably fixed with a pressing roller horizontally extending towards the laying central axis. The distance between the inner end of the pressing roller and the laying central axis is less than or equal to 2 mm;

[0009] The pressing roller presses on the upper surface of the whole cable and is lifted by the liftable rectangular rod along with the laying process of the cable to ensure the flatness of the upper surface of the whole cable.

[0010] Further, a plurality of vertically limiting rollers with self-rotation settings are fixedly arranged on the cable laying chassis at equal intervals. The outer circumference of the vertically limiting rollers is tangent to the rotating chassis, and is used to limit the overall outer diameter of the cable after cable laying. The outer diameter of the inscribed circle of the plurality of vertically limiting rollers is less than or equal to the inner diameter of the cable storage barrel.

[0011] Further, the cable laying central axis is set as a pipe fixed to the center of the rotating chassis at one end, and is used to place the head and tail of the cable reserved during cable laying. A plurality of first arc-shaped opening grooves extending to the bottom end are arranged at equal intervals on the top end face of the cable laying central axis. The outer diameter dimension of the arc-shaped opening grooves is not less than 2 times the outer diameter of the cable. A plurality of wire passing grooves respectively communicating with each opening groove are concavely arranged on the upper surfaces of the rotating chassis and the fixed base, and are used for the tying wire to form a bundle by tying the cable;

[0012] The cable storage shaft is set as a hollow pipe, and at least one second arc-shaped opening groove identical to the rotating circumference is arranged at its top end. The bundled cable is inserted into the outer circumference of the cable storage shaft, and the head and tail of the cable are stored inside the cable storage shaft through the second arc-shaped opening groove. A through hole is arranged at the center of the base, and the head of the cable is connected to the power supply through the through hole. The tail of the cable is connected to the buoy assembly; the cable storage barrel is arranged on the outer circumference of the formed cable, and is fixed to the base for limiting the cable without the tying rope.

[0013] A cable for a small marine buoy is laid by a cable storage and laying device. The cable includes a conductor bunch formed by stranding a plurality of conductors. The pitch diameter ratio of the conductor bunch is 12 times. An insulating layer is arranged on the outer circumference of each conductor, a strengthening layer is arranged on the outer circumference of the conductor bunch, and an outer protective layer is arranged on the outer circumference of the strengthening layer. The tail of the cable is spirally arranged, and a connection section connected to the buoy assembly is reserved. The spirally arranged cable tail is used to relieve the impact of sea waves.

[0014] Further, the conductor is a silver-plated copper conductor, the insulating layer of the conductor is made of FEP material, the strengthening layer is an armored strengthening layer made of water-blocking aramid fiber, and the outer protective layer is made of hydrolysis-resistant polyurethane material.

[0015] A processing and preparation method for a cable for a small marine buoy, which is used to prepare a cable for a small marine buoy, includes the following steps:

[0016] S1: Set the pitch diameter ratio of the conductor bunch to 12 times, and the bunching die adopts a polycrystalline stranding die. The die size is consistent with the designed outer diameter of the stranded conductor;

[0017] S2: Use FEP material as the material of the insulating layer, and extrude the conductor through an extruder by the tube extrusion method. The processing temperatures of each section of the extruder from the feed port to the head are set to 280 - 290 °C, 320 - 330 °C, 340 - 360 °C, 360 - 370 °C, and 370 - 380 °C in sequence;

[0018] S3: Cabling, the cable center is fully filled;

[0019] S4: Water-blocking aramid fiber braided armor reinforcement layer with uniform tension setting;

[0020] S5: Polyether polyurethane is used as the outer sheath material. The processing temperature is set to 130-140℃, 150-170℃, 170-190℃, 170-190℃, and 170-190℃ from the extruder feed port to the extruder head, and pressure extrusion is adopted;

[0021] S6: The cable is wound around a steel rod and heated to prepare a spiral cable tail of the required length;

[0022] S7: Arrange the prepared cables through a cable arrangement device, tie them up with a tying rope, and remove them from the cable arrangement device;

[0023] S8: Put the taken-out cable into a paper cable storage barrel, bond the barrel body and the base with a water-absorbing and softening degradable paper tape, cut the binding rope, and complete the cable packaging;

[0024] S9: Vulcanize and install the buoy assembly at the tail end of the cable in the cable storage shaft, place the installed end spiral and buoy assembly inside the hollow central shaft of the paper cable storage barrel, and complete the packaging of the cable buoy assembly.

[0025] Furthermore, in S6, the specific preparation of the spiral cable tail includes: using a steel rod with a central axis diameter of 20 mm and a length of 1.2 m, leaving a connection section between the cable tail and the buoy assembly, winding the cable tail around the steel rod for about 1 m, placing the steel rod in an oven, setting the oven temperature to 125°C, baking for 1 hour, and cooling to obtain the spiral cable tail.

[0026] Furthermore, in S7, the cable arrangement is specifically as follows: the tail end of the spiral cable is placed inside the cable arrangement axis through the first arc-shaped opening groove, the rotating chassis and the cable arrangement axis are rotated, and the cable is wrapped around the outer periphery of the cable arrangement axis in layers. After the cable arrangement is completed, the binding rope is inserted through the cable groove and tightened. After tightening, the cable is removed from the cable arrangement device.

[0027] Furthermore, in S9, the packaged cables and power supply can be put into seawater for use after installation.

[0028] Compared with the prior art, the beneficial effects of the present invention are mainly reflected in:

[0029] 1. The cable storage barrel of the present invention is a degradable paper structure with low cost. After release, it can soften in the seawater environment within 2 hours and degrade naturally within a week to complete the buoy release without causing environmental pollution. It has low cost and simple deployment operation.

[0030] 2. The cable prepared by the present invention has good transverse water tightness, hydrolysis resistance and strong vulcanization ability: the outer sheath of the cable is extruded and produced from a soft polyether-based polyurethane material, the internal structure of the cable is compact, the insulating layer is made of fluoroplastic material, and the insulation can be relatively thin to ensure that the thickness of the outer sheath meets the requirements, with excellent transverse water tightness. The polyurethane material used in the cable is polyether-based, with good hydrolysis resistance, strong bonding ability with polyurethane glue, and easy vulcanization and installation.

[0031] 3. The cable of the present invention adopts a high-strength water-blocking aramid fiber reinforcing layer. The whole cable can withstand a force of more than 2 kN without damage. And the tail of the cable is set as a spiral shape. Through the conversion of elastic potential energy, the spiral structure effectively avoids the direct impact of the cable by sea waves, and improves the service life of the buoy system.

[0032] 4. The present invention pre-packages the cable into a cable storage barrel through a cable storage and winding device. The head and tail of the cable extend out or are placed inside the cable storage shaft. When in use, it is taken out, which is convenient for connecting with the buoy and the battery.

[0039] The following will describe in more detail a cable for a small marine buoy, its manufacturing method, and the design of a cable storage and laying device with reference to the schematic diagrams. The preferred embodiments of the present invention are shown, and it should be understood that those skilled in the art can modify the present invention described herein while still achieving the advantageous effects of the present invention. Therefore, the following description should be understood as a broad guidance for those skilled in the art and not as a limitation to the present invention.

[0040] As Figure 1 and 2 shown, a cable 1 for a small marine buoy includes a conductor bunch formed by stranding six conductors 12 with a twelve-fold pitch ratio. An insulating layer 13 is provided on the outer periphery of the conductor 12, and a strengthening layer 14 and an outer protective layer 15 are sequentially provided on the outer periphery of the insulating layer 13.

[0041] Conductor bunch

[0042] The conductor 12 is a silver-plated copper stranded wire, and the insulating layer 13 is made of high-quality FEP as the insulating material. The electrical performance of the wire is good, and the FEP material has good insulation, strength, and mechanical properties, which can effectively protect the transmission unit during use and ensure the service life.

[0043] Strengthening layer 14

[0044] The inside of the cable 1 has water-blocking aramid fibers as an armored strengthening layer. This material has a low specific gravity, is soft, and has strong tensile strength. As a strengthening material, it can effectively improve the load-bearing capacity of the cable 1. The cable 1 can withstand a force of more than 2 kN without breaking, ensuring the reliability of the force application.

[0045] Outer protective layer 15

[0046] The cable 1 uses a high-strength wear-resistant and hydrolysis-resistant polyurethane material as the outer protective material. This material can well protect the inside of the cable 1 and is suitable for the marine working environment. The material can be well bonded with polyurethane glue, facilitating the vulcanization connection of the cable 1 ends.

[0047] The cable head is used to connect to the power supply 5, and the cable tail is used to connect to the buoy assembly 4. It is set as a spiral structure, which effectively avoids the cable 1 directly bearing the impact through the conversion of elastic potential energy and improves the service life of the buoy system.

[0048] Refer to Figures 3 - 5 , a cable storage and laying device for laying and storing the above-mentioned cable 1, including a laying device and a cable storage barrel.

[0049] The cable arrangement device includes a cable arrangement chassis 21, a rotating chassis 22 rotatably mounted at the center of the chassis 21, and a cable arrangement axis 23 fixed concentrically with the rotating chassis 22. The upper surface of the cable arrangement chassis 21 is provided with evenly spaced rectangular slots, each of which houses a movable rectangular rod 26. The rectangular shape prevents the rods 26 from rotating, but allows them to be raised or lowered as the cable is wound around the device. A crimping roller 24 is removably fixed to the rods by bolts. The roller 24 extends toward the cable arrangement axis 23, with the end of the roller 24 no more than 2 mm away from the axis. The roller 24 compacts the upper surface of the cable 1 using the rising and falling rods 26 and its own weight, ensuring a smooth cable during arrangement. Furthermore, the removable roller 24 allows it to be removed after cable arrangement is complete, without affecting the bundling and removal of the cables.

[0050] The cable traversing chassis 21 is also equipped with three equally spaced, movably mounted vertical limit rollers 25. Each of these rollers is capable of rotating on its own surface. The outer periphery of each limit roller 25 is tangential to the outer periphery of the rotating chassis 21. The outer diameter of the inscribed circle of each of the three limit rollers 25 is no larger than the inner diameter of the cable storage barrel 33. This serves to limit the outer diameter of the cable after traversing, ensuring that the cable does not extend beyond the confines of the rotating chassis 22.

[0051] The cable arrangement axis 23 is configured as a pipe with one end fixed to the center of the rotating chassis 22. It is used to place the reserved head and tail of the cable 1 during cable arrangement to avoid obstruction during cable arrangement. The top end surface of the cable arrangement axis 23 is evenly spaced with multiple first arc-shaped opening grooves extending to the bottom end. The outer diameter of the arc-shaped opening grooves is not less than twice the outer diameter of the cable 1. The upper surfaces of the rotating chassis 22 and the cable arrangement chassis 21 are concave with three wire grooves 27 respectively connected to each opening groove. The groove width of the wire groove 27 is greater or less than the groove width of the arc-shaped opening groove. When greater than, its groove width is three times the groove width of the arc-shaped opening groove. After the cable arrangement is completed, it is convenient for the bundling wire to pass through and bundle the cables into shape.

[0052] The cable storage barrel 3 is made of degradable paper material, and includes a base 31 and a cable storage shaft 32 and a cable storage barrel body 33 concentrically fixed on the upper surface of the base 31. The outer diameter of the cable storage shaft 32 is the same as the outer diameter of the cable arrangement shaft 23. The cable storage shaft 32 is also set as a hollow pipe, and a second arc-shaped opening groove is provided on the top that is the same as the cable arrangement shaft 23. The bundled cable 1 is inserted into the outer periphery of the cable storage shaft 32, and the head and tail of the cable 1 are stored in the cable storage shaft 32 through the second arc-shaped opening groove. A through hole 34 is provided in the center of the base 31. The head of the cable 1 is connected to the power supply 5 by passing through the through hole 34, and the tail of the cable 1 is connected to the buoy assembly 4.

[0053] The cable storage barrel body 33 surrounds the outer periphery of the entire cable and is fixedly adhered to the base 31 through a water-absorbing and softening degradable tape or an environmentally friendly glue.

[0054] A processing and preparation method for a cable for a small marine buoy, used to prepare the cable for the small marine buoy as described above, specifically including the following steps:

[0055] Step 1: First, in order to improve the flexibility of the cable 1, the pitch diameter ratio of the conductor bunch strands is approximately about 12 times. The bunching die uses a polycrystalline stranding die, and the die size is the same as the designed outer diameter of the stranded conductor. The surface of the conductor bunch strands is smooth and shiny.

[0056] Step 2: Use FEP material with good temperature resistance, mechanical properties, and excellent insulation performance as the insulating material. Its processing temperature is sequentially set to 280 - 290 °C, 320 - 330 °C, 340 - 360 °C, 360 - 370 °C, 370 - 380 °C at each stage from the feed inlet of the extruder to the head of the extruder, and extrusion tube type extrusion is adopted.

[0057] Step 3: Stranding is carried out at a pitch diameter ratio of 12 times in the color sequence, and the center filling of the stranding is rounded.

[0058] Step 4: Use a water-blocking aramid fiber braided reinforcement layer 14 with uniform tension.

[0059] Step 5: Outer sheath 15: Use a polyether-type polyurethane material with good low-temperature resistance, mechanical properties, and soft texture as the material for the outer sheath 15. Its processing temperature is sequentially set to 130 - 140 °C, 150 - 170 °C, 170 - 190 °C, 170 - 190 °C, 170 - 190 °C at each stage from the feed inlet of the extruder to the head of the extruder, and pressure extrusion is adopted.

[0060] Step 6: Preparation of the helical structure 11 at the tail of the cable: Use a steel rod with a central shaft diameter of φ20 mm and a length of 1.2 m. After leaving 1 m of the tail wiring end, wind the cable for the buoy around the steel rod for about 1 m in length. Place the steel rod in an oven, set the oven temperature to 125 °C, bake for 1 h, and after cooling, the helical structure 11 at the tail of the cable is obtained.

[0061] Step 7: Place the prepared cable for the buoy on the pay-off stand. Through the first vertical slot of the wire arranging central shaft 23, place the tail of the cable 1 inside the wire arranging central shaft 23. Rotate the wire arranging central shaft 23 and the rotating chassis 22, and wind the cable 1 around the wire arranging device layer by layer. Among them, the wire arranging chassis 21 is fixed to the ground, and the wire arranging central shaft 23 and the rotating chassis 22 can rotate to wind the cable 1. When the cable 1 is wound, a bundling rope is passed through the channel formed by the first vertical slot and the horizontally arranged roller 24, the cable 1 is tightened, and then taken out from the wire arranging device.

[0062] Step 8: Thread the removed cable 1 into the cable storage shaft 32 and the base according to the cable storage requirements of the cable storage barrel. Place the cable storage barrel body 33. After gluing the degradable paper cable storage barrel body 33 to the base 31, take out the bundling rope, and the packaging of the offshore buoy cable is completed.

[0063] Step 9: Sulfurize and install the buoy assembly 4 at the end of the cable tail inside the cable storage shaft. Place the installed end helix and the buoy assembly 4 inside the hollow cable storage shaft 32 of the paper cable storage barrel to complete the packaging of the cable buoy assembly 4. When in use, install the head of the cable 1 with the power supply 5 and then it can be put into the sea for use.

[0064] The above are only the preferred embodiments of the present invention and do not impose any limitation on the present invention. Any person skilled in the art within the technical field, without departing from the technical solution of the present invention, makes any form of equivalent substitution or modification and other changes to the disclosed technical solution and technical content of the present invention, which are all within the content of the technical solution of the present invention and still fall within the protection scope of the present invention.
