Description

Technical Field

[0001] The invention belongs to the technical field of offshore underwater components, and in particular relates to an anti-biological attachment buffer energy-absorbing cable. Background Art

[0002] Offshore underwater components mainly refer to sea surface buoy berths, floating foundation offshore wind power generation, navigation lights, buoys, floating drilling platforms, etc. In addition to the important role of underwater components exposed on the sea surface, the mooring system hidden under the sea surface plays a vital role. Conventional mooring uses wire ropes or anchor chains. With the expansion of the use range of mooring cable system devices and the increase of water depth, the mooring cable lengthens and the weight increases accordingly. The buoyancy of the floating body cannot support it, resulting in a bulky structure and high cost of the floating platform. The anchor chain does not have the ability to absorb wind and wave energy. When the navigation mark is affected by wind and waves, it will drive the anchor chain to shake, causing wear at the anchor chain link. In large winds and waves, the anchor chain will be worn and damaged. When the floating body is floating, it will cause a large lateral thrust on the anchor chain, forcing the floating body to be dragged underwater. The increase in the displacement of the floating body will produce a greater buoyancy to float up. At this time, it may drag the sunken rocks on the seabed and cause them to move, which will have a serious adverse effect on the normal use of the floating platform. At the same time, marine organisms (seaweed, shells) are easily attached to the anchor chain. The organisms in the seawater adhere to the surface of the mooring cable to form a biofilm, and organic acids, enzymes, biological waste and other metabolites are accumulated in the biofilm, which destroys the performance of the anti-corrosion coating, accelerates the aging and failure of the coating, increases the roughness and cracking of the surface, and causes the cable material to be corroded. At the same time, the marine organisms attached to the anchor chain are extremely difficult to clean.

[0003] The anchor chain needs to be replaced every 1-2 years. Due to underwater operations, replacement is difficult and consumes a lot of manpower and material resources, and the cycle is long. The normal use of the platform is affected during the replacement period, which greatly increases the operating cost of the underwater platform. Therefore, in order to solve the problems of traditional anchor chains, such as heavy weight, easy corrosion and wear, difficult to clean attachments, and weak absorption of wave energy, it is urgent to develop a cable with buffering energy absorption and anti-biological adhesion to ensure the safety, reliability and durability of the mooring cables of long-term offshore floating platform devices under actual use conditions. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that organisms attach to cables and reduce the durability of cables, and to propose an anti-biological attachment cable buffering energy-absorbing cable.

[0005] In order to achieve the above-mentioned object, the present invention adopts the following technical scheme: an anti-biological attachment cable buffer energy-absorbing cable, comprising a cable body, the outer surface of which is provided with auxiliary components and wear-resistant components;

[0007] As a further description of the above technical solution:

[0008] The rope core is made of carbon fiber, high-strength steel wire, aramid fiber, mixed fiber and steel wire, and the rope core plays the role of fixing the rope and cable and conducting electricity and generating magnetism.

[0009] As a further description of the above technical solution:

[0010] The magnetic rods are called ferromagnetic materials, including iron, nickel, cobalt, and alloys thereof. A plurality of the magnetic rods form a triangular structure.

[0011] As a further description of the above technical solution:

[0012] The wire ropes are intertwined with each other, and the wire ropes are made of at least one of carbon fiber, aramid fiber, glass fiber, basalt fiber, mixed fiber and metal wire.

[0013] As a further description of the above technical solution:

[0014] The buffer waterproof protective cover is made of wear-resistant and pressure-resistant materials, such as carbon steel polyurethane, polyethylene, polypropylene, high-strength polyester fiber, high-strength wear-resistant plastic material, etc.

[0015] As a further description of the above technical solution:

[0016] The spiral coil adopts a long spiral wire, and the spiral coil can be wound around the magnetic rod in one circle or multiple circles.

[0017] As a further description of the above technical solution:

[0018] The auxiliary component comprises an airbag cover, the inner surfaces of the plurality of airbag covers are fixedly connected to the outer surface of the buffer waterproof protective cover, and a connecting air pipe is installed between the plurality of airbag covers.

[0019] As a further description of the above technical solution:

[0020] A cleaning ring is slidably mounted on the outer surface of the buffer waterproof protective cover, the inner surface of the cleaning ring is in contact with the outer surface of the buffer waterproof protective cover, and a sliding ring is fixedly mounted on the outer surface of the cleaning ring.

[0021] As a further description of the above technical solution:

[0022] A sliding hole is arranged on the inner wall of the sliding ring, a ball is movably mounted on the inner surface of the sliding hole, and the inner surface of the sliding hole contacts the outer surface of the connecting air pipe through the ball.

[0023] As a further description of the above technical solution:

[0024] The wear-resistant component includes a wear-resistant sleeve, the outer surface of which is close to both ends of the buffer waterproof protective sleeve and is fixedly connected to the inner surface of the wear-resistant sleeve. A cavity is provided on the inner wall of the wear-resistant sleeve, an oil-absorbing cloth is fixedly installed on the inner wall of the cavity, and a liquid seepage hole is provided on the outer surface of the wear-resistant sleeve.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0026] 1. In the present invention, a magnetic dielectric rod and a spiral coil are provided, and the spiral coil wound on the magnetic dielectric rod will generate a magnetic field. Since multiple groups of magnetic dielectric rods are provided in the rope, a strong local magnetic field will be generated around the rope. After the spiral coil is wound on the magnetic dielectric rod, the whole has a certain deformation ability, and can play a buffering and energy absorption effect when hit by the rope. By sequentially arranging magnetic dielectric rods in each cable, and winding multiple turns of spiral coils on the magnetic dielectric rods, when current passes through the spiral coils, a magnetic field is formed, and then under the mediation of the magnetic dielectric rod to further amplify the magnetic field, a strong local magnetic field is formed around the rope, causing marine organisms to be unwilling to attach. In this process, the spiral coil arranged between the rope core and the outer protective layer can buffer the impact of seawater on the rope like a spring, play an energy absorption role, and protect the internal rope core. The internal energy consumption mechanism enables the rope to stop as soon as possible, thereby improving the wear resistance of the rope and the service life of the rope. Therefore, the anti-biological attachment effect is improved while ensuring the simplicity of the rope structure.

[0027] 2. In the present invention, an auxiliary component is provided. After the rope is fixed, gas is injected into the airbag sleeve through the connecting air pipe. As the gas increases, the airbag sleeve will gradually expand, and the connecting air pipe will also expand. At this time, the rope will float in the sea water or on the sea surface under the lift of the airbag sleeve. When the rope is placed in the sea water, the sea water will sway with the wind, and the rope will also sway with the swaying of the sea water. At this time, the cleaning ring moves back and forth on the outer surface of the buffering and waterproof protective sleeve under the limit of the slip ring to clean the outer surface of the buffering and waterproof protective sleeve. The slip ring moves on the outer surface of the connecting air pipe through the ball in the sliding hole to ensure that the rope floats on the sea surface, which is convenient for the later maintenance of the rope and reduces the difficulty of the rope maintenance. At the same time, the power generated by sea water is used to drive the cleaning ring to clean the outer surface of the rope, which can avoid the generation of scale on the outer surface of the rope and ensure the service life of the rope.

[0028] 3. In the present invention, by providing a wear-resistant component, the two ends of the rope are respectively fixed at appropriate positions. At this time, the two ends of the rope are in contact with the fixed position through the wear-resistant sleeve. When the rope shakes, the wear-resistant sleeve will be squeezed with the fixed position. At this time, the lubricating liquid on the oil-absorbing cloth where the wear-resistant sleeve is squeezed will flow out through the seepage holes, and then flow to between the wear-resistant sleeve and the fixed position. The lubricating liquid is used to reduce the friction between the rope and the fixed position, reduce the wear of the rope when it shakes, reduce the time for the rope to break, and improve the safety, reliability and durability of the rope.

[0038] The cable body 1 includes a rope core 101, and a plurality of magnetic dielectric rods 104 are evenly fixedly installed on the outer surface of the rope core 101. A plurality of groups of ropes 102 are evenly wrapped and installed on the outer surface of the rope core 101. A buffer waterproof protective cover 103 is wrapped and installed on the outer surface of the rope 102. A plurality of turns of spiral coils 105 are wound and installed on the outer surface of the magnetic dielectric rods 104. The rope core 101 is made of carbon fiber, high-strength steel wire, aramid fiber, mixed fiber and steel wire. The rope core 101 plays the role of fixing the rope and conducting magnetism. The magnetic dielectric rods 104 are called ferromagnetic The plurality of magnetic rods 104 form a triangular structure. The wire ropes 102 are intertwined with each other. The wire ropes 102 are made of at least one of carbon fiber, aramid fiber, glass fiber, basalt fiber, mixed fiber and metal wire. The buffer waterproof protective cover 103 is made of wear-resistant and pressure-resistant material, such as carbon steel polyurethane, polyethylene, polypropylene, high-strength polyester fiber, high-strength wear-resistant plastic, etc. The spiral coil 105 is made of a long spiral wire, and the spiral coil 105 can be wound around the magnetic rod 104 in one circle or multiple circles.

[0039] The specific implementation example is as follows: the spiral coil 105 wound on the magnetic rod 104 will generate a magnetic field. Since multiple groups of magnetic rods 104 are arranged in the cable, a strong local magnetic field will be generated around the cable. After the spiral coil 105 is wound on the magnetic rod 104, the whole has a certain deformation ability, which can play a buffering and energy absorption effect when hit by the cable.

[0040] The auxiliary component 2 includes an airbag cover 201, and the inner surfaces of multiple airbag covers 201 are fixedly connected to the outer surface of the buffering and waterproof protective cover 103. A connecting air pipe 202 is installed between the multiple airbag covers 201. A cleaning ring 204 is slidably installed on the outer surface of the buffering and waterproof protective cover 103. The inner surface of the cleaning ring 204 fits the outer surface of the buffering and waterproof protective cover 103. A sliding ring 203 is fixedly installed on the outer surface of the cleaning ring 204. A sliding hole 205 is provided on the inner wall of the sliding ring 203. A ball 206 is movably installed on the inner surface of the sliding hole 205. The inner surface of the sliding hole 205 contacts the outer surface of the connecting air pipe 202 through the ball 206.

[0041] The specific implementation example is as follows: after the cable is fixed, gas is injected into the airbag cover 201 through the connecting air pipe 202. As the gas increases, the airbag cover 201 will gradually expand, and the connecting air pipe 202 will also expand. At this time, the cable will float in the sea water or on the sea surface under the lift of the airbag cover 201. When the cable is placed in the sea water, the sea water will sway with the wind, and the cable will also sway with the swaying of the sea water. At this time, the cleaning ring 204 moves back and forth on the outer surface of the buffering waterproof protective cover 103 under the limitation of the slip ring 203 to clean the outer surface of the buffering waterproof protective cover 103, and the slip ring 203 moves on the outer surface of the connecting air pipe 202 through the ball 206 in the sliding hole 205.

[0042] The wear-resistant component 3 includes a wear-resistant sleeve 301, and the outer surfaces near the two ends of the buffer waterproof protection sleeve 103 are fixedly connected to the inner surface of the wear-resistant sleeve 301. A cavity is provided on the inner wall of the wear-resistant sleeve 301, and an oil-absorbing cloth 303 is fixedly installed on the inner wall of the cavity. The outer surface of the wear-resistant sleeve 301 is provided with seepage holes 302.

[0043] The specific implementation method is as follows: the two ends of the rope are fixed at appropriate positions respectively, at which time the two ends of the rope are in contact with the fixed position through the wear-resistant sleeve 301. When the rope shakes, the wear-resistant sleeve 301 will be squeezed with the fixed position. At this time, the lubricating liquid on the oil-absorbing cloth 303 at the place where the wear-resistant sleeve 301 is squeezed will flow out through the seepage hole 302, and then flow between the wear-resistant sleeve 301 and the fixed position.

[0044] Working principle: fix the two ends of the rope at appropriate positions respectively, at which time the two ends of the rope are in contact with the fixed position through the wear-resistant sleeve 301. When the rope shakes, the wear-resistant sleeve 301 will be squeezed with the fixed position. At this time, the lubricating liquid on the oil-absorbing cloth 303 where the wear-resistant sleeve 301 is squeezed will flow out through the seepage hole 302, and then flow to between the wear-resistant sleeve 301 and the fixed position. After the rope is fixed, inject gas into the airbag sleeve 201 through the connecting air pipe 202. As the gas increases, the airbag sleeve 201 will gradually expand, and the connecting air pipe 202 will also expand. At this time, the rope will float in the sea water or on the sea surface under the lift of the airbag sleeve 201. When the rope is placed in the sea water As the sea water will sway with the wind, the cable will also sway with the swaying of the sea water. At this time, the cleaning ring 204 moves back and forth on the outer surface of the buffering waterproof protective cover 103 under the limit of the slip ring 203 to clean the outer surface of the buffering waterproof protective cover 103. The slip ring 203 moves on the outer surface of the connecting air pipe 202 through the ball 206 in the sliding hole 205. The spiral coil 105 wrapped around the magnetic dielectric rod 104 will generate a magnetic field. Since multiple groups of magnetic dielectric rods 104 are arranged in the cable, a strong local magnetic field will be generated around the cable. After the spiral coil 105 is wrapped around the magnetic dielectric rod 104, the whole has a certain deformation ability, which can play a buffering and energy absorption effect when hit by the cable.
