Description

Technical Field

[0001] The invention belongs to the technical field of submarine cable transporters, in particular to a submarine cable transporter in a seabed trench. Background Art

[0002] Submarine cables are cables wrapped in insulating materials, laid on the seabed and used for telecommunications transmission. Submarine cables are divided into submarine communication cables and submarine power cables. Modern submarine cables all use optical fiber as material to transmit telephone and Internet signals.

[0003] When transporting and laying submarine cables, submarine cable construction vessels are needed. After the submarine cables are transported to the appropriate location by the submarine cable construction vessel, the submarine cables are dropped to the seabed for laying through the cooperation of the crane and internal transmission mechanism inside the submarine cable transport ship.

[0004] When the submarine cable construction ship is transporting the submarine cable for laying, the submarine cable will eventually be dropped into the seabed through the guide platform on the submarine cable construction ship. However, due to the sea breeze and seawater, the submarine cable construction ship will continue to shake, causing the submarine cable to shake with it, which will easily cause the submarine cable to twist and cause internal damage. The shaking submarine cable will also continue to rub against the guide platform. At the same time, because the submarine cable is stored in stacks, it will continue to rub against the conveying equipment when it is transported out of the cable drum, which can easily damage the anti-corrosion layer on the surface of the submarine cable, resulting in poor subsequent anti-corrosion effects, and thus requiring frequent maintenance, which greatly reduces the service life of the submarine cable.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The submarine cable carrier in the submarine trench of the present invention allows the electric push rod to drive the slider, telescopic assembly and other parts to move, so as to facilitate the submarine cable body to enter between the two positioning plates and the two guide plates, and the guide column on the guide plate plays a role in assisting the movement of the submarine cable body, thereby reducing the friction on the submarine cable body. Since the slider will move with the slide bar when moving, the magnetic material surface of the slide bar and the magnetic material surface of the connecting plate attract each other, and then the slide bar slides toward the connecting plate, and the lubricating oil in the oil storage box slowly drips onto the surface of the rotating ball through the oil pipeline, thereby further reducing the friction between the rotating ball and the submarine cable body. The above-mentioned structure can reduce the wear of the submarine cable body during transportation, and can also effectively limit the position of the submarine cable body, so as to prevent the submarine cable body from shaking continuously due to the shaking of the submarine cable construction ship when transporting the submarine cable body at sea, resulting in the internal parts of the submarine cable body being twisted and damaged after being bent for a long time and many times. It also effectively prevents the submarine cable body from deviating from the predetermined route after shaking, which makes it difficult to perform the transportation work normally.

[0019] 2. The submarine cable carrier in the submarine trench described in the present invention uses an air compressor to draw the anti-adhesion liquid in the storage box into the spray gun and spray it onto the surface of the submarine cable body through the spray hole of the protective cover, thereby forming an anti-biological adhesion coating on the surface of the submarine cable. The anti-biological adhesion coating can prevent biological adhesion, thereby protecting the submarine cable body. At the same time, the dripping liquid after spraying will fall into the protective cover and re-enter the storage box through the reflux pipe for collection and reuse, thereby avoiding the waste of dripping liquid and effectively preventing the dripping liquid from flowing onto the submarine cable construction ship, resulting in increased cleaning work for the staff. Through the heating wire in the jet pipe, the gas sprayed from the jet pipe is heated by the heating wire and becomes hot air, which is then blown onto the surface of the submarine cable body, achieving the effect of quickly drying the sprayed liquid. Rapid drying can reduce the chance of external impurities and pollutants adhering to the coating surface, thereby maintaining the purity and functionality of the coating. At the same time, the rapidly formed coating has a more uniform structure and higher sealing, which helps to improve the durability and corrosion resistance of the coating.

[0020] 3. The submarine cable carrier in the submarine trench described in the present invention moves with the fixed rod and the sealing plate when the slider moves. The sealing plate also squeezes the gas in the second chamber and sprays it to the guide platform through the outlet pipe while moving, thereby pre-cleaning the guide platform and reducing the impurities remaining on the guide platform and affecting the subsequent transportation of the submarine cable body. After the submarine cable body is transported, the slider resets with the fixed rod and the sealing plate. When the sealing plate is reset, it squeezes water into the outlet pipe and sprays it to the surface of the guide platform through the outlet hole, thereby flushing the guide platform and reducing the impurities and liquid residues on the guide platform. At this time, the elastic block in the chute also plays a role in filling the gap and preventing water from flowing into the chute. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0045] like Figures 1 to 11 As shown, a submarine cable carrier in a submarine trench according to an embodiment of the present invention comprises a submarine cable construction vessel 1, on which a cable drum 2 for loading a submarine cable body 3 is installed, and the submarine cable construction vessel 1 is also provided with a hoist 4 for assisting in lifting the submarine cable body 3, and a guide platform 5 for assisting the submarine cable body 3 in entering the sea; a positioning mechanism 10 for limiting the position of the submarine cable body 3 is provided on the guide platform 5, and the positioning mechanism 10 comprises a plurality of slide grooves 11 provided on the guide platform 5, and a rolling column 12 is connected to the interior of the slide groove 11 through a rotating shaft, and the guide platform 5 Two rectangular grooves 13 are symmetrically provided on the upper surface, and an electric push rod 14 is fixedly installed inside the rectangular groove 13. A slider 15 is slidably connected inside the rectangular groove 13 through the electric push rod 14. A positioning plate 16 is provided at one end of the two sliders 15 close to each other, and a plurality of rotating balls 17 are engraved on one side of the two positioning plates 16 close to each other. An oil storage box 18 is fixedly installed on the top of the positioning plate 16, and an oil delivery pipe 19 connected to the inside is installed on one side of the oil storage box 18. The end of the oil delivery pipe 19 away from the oil storage box 18 is connected to the rotating ball 17 in the positioning plate 16. A flow guide mechanism 50 is provided on one side of the positioning plate 16, and the flow guide mechanism 50 includes an arc-shaped flow guide plate 51 fixedly installed with the positioning plate 16, and a plurality of flow guide columns 52 are rotatably connected to one side of the flow guide plate 51.

[0046] Specifically, a telescopic component 20 capable of sealing and dustproofing is provided in the rectangular groove 13. The telescopic component 20 is composed of a plurality of hollow sliding plates. One end of the telescopic component 20 is fixedly connected to the rectangular groove 13 of the guide platform 5, and the other end of the telescopic component 20 is fixedly connected to the slider 15. A control component 40 for controlling the opening and closing of the oil storage box 18 is provided on the telescopic component 20. The control component 40 includes a slide rod 41 that slides on the slider 15 through a spring, and one end of the slide rod 41 abuts against a port of the oil pipe 19 in the oil storage box 18. The slide rod 41 is sealingly and slidably connected to the oil storage box 18, and a plurality of rubber sealing rings are fixedly installed on the surface. A connecting plate 42 is fixedly installed on the top of the telescopic component 20, and the sides of the connecting plate 42 and the slide rod 41 that are close to each other are made of magnetic materials that attract each other.

[0047] Specifically, a deformation component 80 is provided on the guide platform 5, and the deformation component 80 includes a ball head 81 for connecting the slider 15 and the positioning plate 16. A plurality of rolling balls 82 are rollingly connected to the surface of the rolling column 12. A baffle plate 83 is fixedly installed on one side of the positioning plate 16. A hollow elastic frame 84 is fixedly installed on the side where the two baffle plates 83 are close to each other. Shrinkage holes are opened on the surface of the elastic frame 84. A connecting pipe 85 connected to the shrinkage hole of the elastic frame 84 is fixedly installed on one side of the baffle plate 83.

[0048] During operation, when the submarine cable body 3 on the submarine cable construction ship 1 is hoisted onto the guide platform 5 by a conveying mechanism such as a crane 4, the electric push rod 14 in the rectangular groove 13 is first started, so that the electric push rod 14 drives the slider 15, the telescopic assembly 20, the guide plate 51 and the positioning plate 16 to move together. The telescopic assembly 20 can move in coordination with the electric push rod 14, thereby reducing impurities entering the rectangular groove 13 and affecting the operation of the equipment.

[0049] When the slider 15 moves with the positioning plate 16 and the guide plate 51, the purpose is to increase the gap between the two positioning plates 16 and the two guide plates 51, so as to facilitate the entry of the submarine cable body 3, and the guide column 52 on the guide plate 51 plays a role in assisting the submarine cable body 3 to move, thereby reducing the friction on the submarine cable body 3. As the submarine cable body 3 passes through the two guide plates 51 and enters between the two positioning plates 16, it will contact the rotating ball 17 between the two positioning plates 16 and the rolling column 12 on the guide platform 5. Since the slider 15 moves with the slide bar 41, the magnetic material surface of the slide bar 41 and the magnetic material surface of the connecting plate 42 attract each other (the connecting plate 42 and the slide bar 41 are at the same height, so they can attract each other), and then the slide bar 41 slides toward the connecting plate 42, so that one end of the slide bar 41 no longer abuts against the port of the oil pipeline 19, allowing the lubricating oil in the oil storage box 18 to pass through the oil pipeline. The oil pipe 19 slowly drips onto the surface of the rotating ball 17 (the rotating ball 17 is wedged into the groove of the positioning plate 16, and each groove of the positioning plate 16 is connected to the oil pipe 19. The oil pipe 19 first delivers oil to the groove of the positioning plate 16 and then drips onto the surface of the rotating ball 17), thereby further reducing the friction between the rotating ball 17 and the submarine cable body 3. It should be noted that the slide bar 41 slides on the slider 15 through the spring, so that when the slide bar 41 and the connecting plate 42 are no longer attracted to each other, the spring can bring the slide bar 41 to reset and block the port of the oil pipe 19 to prevent the oil pipe 19 from continuing to transport lubricating oil. At the same time, the rolling column 12 in the slide groove 11 is used to send the submarine cable body 3 into the sea, which greatly improves the transportation efficiency of the submarine cable body 3, thereby avoiding the direct contact between the submarine cable body 3 and the surface of the guide platform 5, which leads to increased wear.

[0050] It should be noted that the ball is installed between the slider 15 and the positioning plate 16 so that when the submarine cable construction ship 1 is swaying laterally, the positioning plate 16 can be slightly rotated by clamping the submarine cable body 3 through the ball head 81, so as to cooperate with the swaying and avoid the submarine cable body 3 from being damaged. When the positioning plate 16 shakes, it will shake with the oil storage box 18. At this time, the slide rod 41 connected to the oil storage box 18 is set to a rubber material so that it can rotate in coordination with the deformation and prevent the slide rod 41 from being unable to rotate because it is made of a hard material. At the same time, a number of rolling balls 82 are installed on the rolling column 12 to reduce friction when the submarine cable body 3 is swaying laterally. Because of the shaking of sea water, the submarine cable body 3 shakes, and the baffle 83 and the elastic frame 84 will shake with the submarine cable body 3. At the same time, the submarine cable body 3 will squeeze the elastic frame 84, and the gas in the elastic frame 84 will be squeezed and then enter the connecting pipe 85 through the shrinkage hole and sprayed out, and the sea water that is hit towards the guide platform 5 due to the shaking will be blown off the guide platform 5, thereby reducing the corrosion of the guide platform 5 by sea water.

[0051] The above-mentioned structure can reduce the wear of the submarine cable body 3 during transportation, and can also effectively limit the position of the submarine cable body 3 to prevent the submarine cable body 3 from shaking continuously due to the shaking of the submarine cable construction ship 1 when the submarine cable body 3 is transported at sea, causing the internal parts of the submarine cable body 3 to be twisted and damaged after being bent for a long time and multiple times. It can also effectively prevent the submarine cable body 3 from deviating from the predetermined route after shaking, making it difficult to carry out the transportation work normally.

[0052] A spraying mechanism 30 for spraying the surface of the submarine cable body 3 is provided on the guide platform 5. The spraying mechanism 30 includes a storage box 31 fixedly installed on one side of the guide platform 5. A storage box 32 containing liquid is fixedly installed inside the storage box 31. A spray gun 34 is fixedly installed on the top of the storage box 31. The spray gun 34 and the storage box 32 are connected through an air compressor 33.

[0053] Specifically, a protective cover 35 is fixedly installed on the top of the spray gun 34, and a plurality of spray holes 36 connected to the spray gun 34 are provided in the protective cover 35. A return pipe 37 connected to the storage box 32 is fixedly installed in the protective cover 35. A drying assembly 38 for quickly drying the liquid is provided on the top of the storage box 31. The drying assembly 38 includes an air jet pipe 381 connected to the air compressor 33. The air compressor 33 is provided with a plurality of air inlets and air outlets. A plurality of air jet ports are provided at one end of the air jet pipe 381 away from the air compressor 33. A heating wire 382 is electrically connected in the air jet pipe 381. An end cap 383 is rotatably connected to the air jet port of the air jet pipe 381 through a torsion spring, and two arc-shaped guide plates 384 are fixedly installed on one side of the end cap 383. An air blowing auxiliary mechanism 60 is arranged in the slide groove 11, and the auxiliary mechanism 60 includes a hollow elastic block 62 fixedly installed in the slide groove 11, and a pressure plate 61 fixedly installed on the rotating shaft. A plurality of air outlet holes 63 with waterproof and breathable cloth are opened on the surface of the guide platform 5, and the elastic block 62 and the air outlet holes 63 are connected by a flexible tube.

[0054] During operation, when the submarine cable body 3 is transported to a place close to the guide platform 5, the air compressor 33 in the storage box 31 is started, so that the air compressor 33 draws the anti-adhesion liquid (which may be silica gel, polyvinyl alcohol (PVA) and polyethylene, which can be selected according to actual conditions) in the storage box 32 into the spray gun 34 and sprays it onto the surface of the submarine cable body 3 through the spray hole 36 of the protective cover 35, thereby forming an anti-biological adhesion coating on the surface of the submarine cable. The anti-biological adhesion coating can prevent biological adhesion, thereby protecting the submarine cable body 3.

[0055] At the same time, the dripping liquid after spraying will fall into the protective cover 35 and re-enter the storage box 32 through the reflux pipe 37 for collection and reuse, thus avoiding the waste of the dripping liquid and effectively preventing the dripping liquid from flowing onto the submarine cable construction vessel 1, thereby increasing the cleaning work of the staff.

[0056] Since the air compressor 33 can have multiple air inlets and outlets, a jet pipe 381 is installed on another air outlet of the air compressor 33. When the submarine cable body 3 completes the spraying of the liquid, the heating wire 382 in the jet pipe 381 is started, so that the gas sprayed from the jet pipe 381 is converted into hot air after being heated by the heating wire 382, ​​and then blown to the surface of the submarine cable body 3, thereby achieving the effect of quickly drying the sprayed liquid. Rapid drying can reduce the chance of external impurities and pollutants adhering to the coating surface, thereby maintaining the purity and functionality of the coating. At the same time, the rapidly formed coating has a more uniform structure and higher sealing, which helps to improve the durability and corrosion resistance of the coating. Since the submarine cable body 3 contacts the rolling column 12 when being transported on the guide platform 5 and drives the rolling column 12 to rotate, the rotating shaft will also rotate, and the rotating shaft brings the pressing plate 61 to continuously squeeze the elastic block 62, so that the gas in the elastic block 62 enters the air outlet 63 through the flexible tube and blows to the bottom of the submarine cable body 3 (since the submarine cable body 3 contacts the fixed column, there will be a certain gap between the bottom of the submarine cable body 3 and the air outlet 63), thereby further assisting in drying the coating on the surface of the submarine cable body 3. At the same time, the waterproof and breathable cloth installed on the air outlet can also prevent the undried coating liquid from dripping in, effectively preventing the occurrence of poor effect due to the undried coating.

[0057] A cleaning mechanism 70 for flushing the fixed column is provided on the guide platform 5. The cleaning mechanism 70 includes a plurality of rectangular frames 71 fixedly mounted on the guide platform 5. A fixed rod 72 is slidably connected inside the rectangular frame 71. One end of the fixed rod 72 is fixedly connected to the slider 15. A sealing plate 73 is sealingly slidably connected inside the rectangular frame 71. The sealing plate 73 is fixedly connected to the fixed rod 72. The sealing plate 73 divides the rectangular frame 71 into a first chamber 74 and a second chamber 75. One side of the rectangular frame 71 is externally connected to a water inlet pipe 76 and a water outlet pipe 77 connected to the first chamber 74. A plurality of water outlet holes 78 are provided on the surface of the water outlet pipe 77.

[0058] Specifically, a blowing assembly 79 for pre-cleaning the guide platform 5 is provided in the rectangular frame 71, and the blowing assembly 79 includes a hollow elastic ball 791 fixedly installed in the second chamber 75, one end of the elastic ball 791 is fixedly connected to the sealing plate 73, and a shrinkage hole is opened on the surface of the elastic ball 791. An air outlet pipe 792 connected to the second chamber 75 is fixedly installed on one side of the rectangular frame 71, and one end of the air outlet pipe 792 away from the rectangular frame 71 is aligned with the rolling column 12.

[0059] During operation, when the slider 15 moves, it will move with the fixing rod 72, and the fixing rod 72 will move with the sealing plate 73 in the rectangular frame 71. The sealing plate 73 will suck the water source connected to the water inlet pipe 76 into the first chamber 74, and the sealing plate 73 will squeeze the elastic ball 791 in the second chamber 75 while moving, so that the gas in the elastic ball 791 enters the second chamber 75 through the shrinkage hole, and cooperates with the gas in the second chamber 75 to spray to the guide platform 5 through the outlet pipe 792, thereby pre-cleaning the guide platform 5 and reducing the impurities remaining on the guide platform 5 and affecting the subsequent transportation cooperation of the submarine cable body 3.

[0060] After the submarine cable body 3 is transported, the slider 15 is reset with the fixing rod 72 and the sealing plate 73. At this time, the first chamber 74 in the rectangular frame 71 is filled with water. When the sealing plate 73 is reset, the water is squeezed into the water outlet pipe 77 and sprayed onto the surface of the guide platform 5 through the water outlet hole 78, thereby flushing the guide platform 5 and reducing the impurities and coating liquid residue on the guide platform 5. At this time, the elastic block 62 in the chute 11 also plays a role in filling the gap and preventing water from flowing into the chute 11.

[0061] Working principle: When the submarine cable body 3 on the submarine cable construction ship 1 is hoisted onto the guide platform 5 by a conveying mechanism such as a crane 4, the electric push rod 14 in the rectangular groove 13 is first started, and the electric push rod 14 drives the slider 15, the telescopic assembly 20, the guide plate 51 and the positioning plate 16 to move together. The telescopic assembly 20 can move in coordination with the electric push rod 14. When the slider 15 moves with the positioning plate 16 and the guide plate 51, the gap between the two positioning plates 16 and the two guide plates 51 is increased, so that the submarine cable body 3 can enter easily. As the submarine cable body 3 passes through the two guide plates 51 and enters between the two positioning plates 16, it will contact the rotating ball 17 between the two positioning plates 16 and the rolling column 12 on the guide platform 5. Since the slider 15 will move with the slide bar 41 when it moves, the magnetic material surface of the slide bar 41 and the magnetic material surface of the connecting plate 42 will attract each other, so that the slide bar 41 slides toward the connecting plate 42, so that one end of the slide bar 41 no longer abuts against the port of the oil pipe 19, allowing the lubricating oil in the oil storage box 18 to slowly drip onto the surface of the rotating ball 17 through the oil pipe 19.

[0062] When the submarine cable body 3 is transported to a position close to the guide platform 5, the air compressor 33 in the storage box 31 is started, so that the air compressor 33 draws the anti-adhesion liquid in the storage box 32 into the spray gun 34 and sprays it onto the surface of the submarine cable body 3 through the spray hole 36 of the protective cover 35. At the same time, the dripping liquid after spraying will fall into the protective cover 35 and re-enter the storage box 32 through the return pipe 37 for collection and reuse. Since the air compressor 33 can have multiple air inlets and outlets, a jet pipe 381 is installed on another air outlet of the air compressor 33. When the submarine cable body 3 completes the liquid spraying, the heating wire 382 in the jet pipe 381 is started, so that the gas sprayed from the jet pipe 381 is heated by the heating wire 382 and becomes hot air, and then blows onto the surface of the submarine cable body 3, so as to achieve the effect of quickly drying the sprayed liquid. Since the submarine cable body 3 contacts the rolling column 12 when being transported on the guide platform 5 and drives the rolling column 12 to rotate, the rotating shaft will also rotate. The rotating shaft brings the pressure plate 61 to continuously squeeze the elastic block 62, so that the gas in the elastic block 62 enters the air outlet 63 through the flexible tube and blows to the bottom of the submarine cable body 3, thereby further assisting in drying the coating on the surface of the submarine cable body 3.

[0063] When the slider 15 moves, it will move with the fixing rod 72, and the fixing rod 72 will move with the sealing plate 73 in the rectangular frame 71. The sealing plate 73 will suck the water source connected to the water inlet pipe 76 into the first chamber 74, and the sealing plate 73 will squeeze the elastic ball 791 in the second chamber 75 while moving, so that the gas in the elastic ball 791 enters the second chamber 75 through the shrinkage hole, and cooperates with the gas in the second chamber 75 to spray to the guide platform 5 through the outlet pipe 792, thereby playing a role in pre-cleaning the guide platform 5. After the submarine cable body 3 is transported, the slider 15 returns to its original position with the fixing rod 72 and the sealing plate 73. At this time, the first chamber 74 in the rectangular frame 71 is filled with water. When the sealing plate 73 returns to its original position, it will squeeze the water into the outlet pipe 77 and spray to the surface of the guide platform 5 through the outlet hole 78, thereby achieving the flushing of the guide platform 5.
