Technical Field

[0001] The present invention relates to the field of submarine optical cable positioning and communication technology, in particular to a buoy positioning intelligent submarine optical fiber cable system. Background Art

[0002] Submarine optical cable communications are an important part of modern communication networks. They transmit data through optical cables laid on the seabed and connect communication systems around the world.

[0003] The buoy system is a widely used device in ocean monitoring, which can provide important data about the marine environment, including meteorological, hydrological and water quality information.

[0004] Submarine cables are damaged by ships dropping anchors from time to time, often leading to communication interruptions, causing economic losses, and potentially affecting international communications. To prevent such incidents, crew members are usually required to check for the possibility of anchor chain slippage during the voyage, or the patrol and control of the Coast Guard reminds ships of the presence of submarine cable facilities in nearby waters. However, it is impossible to predict the location of the submarine cable in advance and avoid dropping anchor at the location of the submarine cable. In addition, the regular maintenance of submarine cables currently requires manual underwater inspection, resulting in high subsequent use costs, long inspection cycles, and very limited inspection timeliness. Summary of the invention

[0011] An embedded light intensity sensor is installed on the outer side of the buoy body at the upper end of the lateral storage groove.

[0012] The buoy body is provided with an internal energy replenishing chamber with an opening at the lower end, and the electrically controlled lifting platform includes a side separation cover plate arranged at the opening position at the lower end of the internal energy replenishing chamber, an electrically controlled correction frame slidably mounted on the side separation cover plate, a lifting strut rod for controlling the lifting and lowering of the side separation cover plate, and an angle adjustment strut rod for controlling the flipping of the side separation cover plate.

[0013] A built-in flow guide device is installed on the top surface of the internal energy replenishment chamber.

[0014] The split detection module comprises a main frame, electric drive blades mounted on both sides of the main frame through lateral mounting arms, an electric control guide support cover movably mounted on both sides of the lower end of the main frame, and an optical recognition module.

[0015] A side-mounted flow guide cover that matches the built-in flow guide device is fixedly mounted on the inner side surface of the internal energy replenishment chamber.

When the electric control screw rod 21 controls the internal thread translation block 22, the assembly frame 23 and the bottom floating block 24 to adjust outward by rotating, the entire buoy body 1 will lower its height, and then the electric control lifting platform 4 will descend, and then the split detection module 5 will be released into the sea water, and then the electric control lifting platform 4 will flip down and open, and the split detection module 5 will move along the sea water by itself. The anchor chain moves to the position of the submarine cable, and then the entire buoy is reset and lifted; after the detection is completed, it rises to the bottom of the buoy body 1 by itself, and then the buoy is controlled to be lowered again, the electric-controlled lifting platform 4 is opened, and the split detection module 5 is driven into the inside of the electric-controlled lifting platform 4, and the split detection module 5 is lifted into the inside of the buoy body 1 through the electric-controlled lifting platform 4, and then the split detection module 5 is energized and communicated, and the detection data is remotely transmitted to the monitoring terminal, thereby completing the purpose of autonomous detection, autonomous energy supply and autonomous positioning.

[0027] In order to facilitate lateral storage and assembly, a plurality of lateral storage grooves for installing the angle-adjustable photovoltaic panels 3 are provided on the outer side surface of the buoy body 1 .

[0028] In order to facilitate angle adjustment, the angle-adjustable photovoltaic panel 3 includes a flip assembly substrate 31 movably installed inside the lateral storage groove through two side axes, an internal support rod 32 for controlling the flipping of the flip assembly substrate 31, and a photovoltaic power generation panel 33 fixedly installed on the flip assembly substrate 31.

[0031] The light intensity in different directions is monitored by the embedded light intensity sensor 7 , and then the photovoltaic power generation panel 33 at the position with weaker light intensity is controlled to flip by extending the built-in support rod 32 , thereby improving the power generation efficiency of the photovoltaic power generation panel 33 .

[0032] In order to cooperate with the internal lifting adjustment and energy replenishment, the buoy body 1 is provided with an internal energy replenishment chamber 8 with an opening at the lower end. The electrically controlled lifting platform 4 includes a side separation cover plate 41 arranged at the opening position at the lower end of the internal energy replenishment chamber 8, an electrically controlled correction frame 42 slidably installed on the side separation cover plate 41, a lifting strut 43 for controlling the lifting and lowering of the side separation cover plate 41, and an angle adjustment strut 44 for controlling the flipping of the side separation cover plate 41.

[0033] The lifting strut 43 is lifted and lowered by telescopically controlling the side separation cover 41, while the angle adjustment strut 44 is flipped and adjusted by telescopically controlling the side separation cover 41. The cylinder end of the angle adjustment strut 44 is movably mounted on the outside of the cylinder of the lifting strut 43. The cylinder of the lifting strut 43 is fixed at an angle position in the internal energy replenishing chamber 8, and the telescopic ends of the lifting strut 43 and the angle adjustment strut 44 are movably connected to the upper surface of the side separation cover 41.

[0034] The electrically controlled correction frame 42 is composed of a translation strut installed on the side separation cover 41 and a lateral correction frame fixed on the protruding end of the translation strut. The lateral correction frame is controlled to translate on the upper surface of the side separation cover 41 by contracting the translation strut, thereby correcting the limit of the split detection module 5 and improving its stability during the energy replenishment process. The lifting energy replenishment column on the top is sleeved on the electrically controlled lifting energy replenishment terminal on the upper end of the split detection module 5 to cooperate with the energy replenishment. At the same time, it can also facilitate the rapid transmission of the detection data of the split detection module 5 to the communication equipment inside the buoy body 1, and then transmit the data results to the remote control terminal through the wireless transmission communication equipment.

[0035] The control method of the electrically controlled lifting energy supply terminal and the lifting energy supply column at the upper end of the split detection module 5 is the existing technology. The power supply end of the angle-adjustable photovoltaic panel 3 and the input end of the split detection module 5 are connected in series by putting the energy supply column on the electrically controlled lifting energy supply terminal, thereby supplying power in series. A top closing cover is elastically mounted on the electrically controlled lifting energy supply terminal on the upper surface of the split detection module 5.

[0039] The entire main frame 51 is controlled to translate and rise and fall in the sea water by rotating the electric drive blades 52 on both sides of the main frame 51. The optical recognition probe on its outside is lowered along the anchor chain to the position of the submarine cable, and then the electric control guide support cover 53 is unfolded outward, and the electric control guide support cover 53 is flipped to both sides of the submarine cable, and then translated along the submarine cable. Optical scanning is performed by the optical recognition module 54 located at the bottom of the main frame 51 and on the inner wall of the electric control guide support cover 53, so as to detect the damage, dirt accumulation and operating temperature of the surface of the submarine cable.
