Description

Technical Field

[0001] The utility model relates to the technical field of underwater robots, in particular to an optoelectronic composite cable inspection device based on an underwater robot. Background Art

[0002] Submarine cables mainly include submarine cables, submarine optical cables and submarine optoelectronic composite cables. Submarine optical cable communication has become the most important means of communication internationally due to its advantages such as large capacity, high quality and low price, accounting for more than 95% of the world's international data communication volume. With the rapid development of Internet-related services such as 5G and cloud services, the demand for data communication has exploded, and the demand for submarine optical cable bandwidth and quantity has increased rapidly. Submarine cables play a huge role in the field of power transmission such as marine wind power generation and inter-island power transmission. Submarine cables are often disturbed by natural and human factors such as tsunamis, earthquakes, and anchoring, and are often in abnormal operating conditions such as damage, breakage, and suspension. For example, on February 27, 2004, in the submarine cable protection area near the Shantou landing station of the international submarine optical cable, the Asia-Europe international submarine optical cable failed due to illegal operations of dredging ships, resulting in communication interruption for more than 10 days. Therefore, accurately exploring the submarine cable route and daily tracking and inspection are important tasks in the daily maintenance of submarine cables.

[0003] Submarine cables, especially in offshore areas, are mostly buried in the seabed to minimize the risks of natural and human factors to the operation of submarine cable systems. Submarine optical cables, especially submarine optical cables, have small diameters and are buried in the seabed, which makes it difficult for conventional underwater acoustic and optical detection equipment to accurately locate their routing information. Therefore, we provide an optoelectronic composite cable inspection device based on an underwater robot. Utility Model Content

The first vertical thruster 9 and the second vertical thruster 10, three probe rods 18 distributed in the left, middle and right positions are fixedly installed on the front bottom side of the upper bracket 4, and the surface of the probe rods 18 is wound with a coil 19, and a controller 14, a locator 15 and a current sensor 20 are fixedly installed in the middle of the upper end of the upper bracket 4. The first horizontal thruster 5, the second horizontal thruster 6, the third horizontal thruster 7 and the fourth horizontal thruster 8 can drive the inspection device to move 360° in the horizontal direction. The first vertical thruster 9 and the second vertical thruster 10 can drive the inspection device to move up and down in the vertical direction, which greatly increases the flexibility of the inspection device.

[0022] A battery compartment 22 is fixedly mounted in the middle of the upper end of the bottom bracket 1 , and the battery compartment 22 is used to supply power to the entire inspection device.

[0023] The coil 19 is electrically connected to a current sensor 20 , and the current generated by the coil 19 is detected by the current sensor 20 .

[0024] The four corners of the upper end of the upper bracket 4 are fixedly installed with buoyancy blocks 13, and the four corners of the bottom of the bottom bracket 1 are fixedly installed with counterweight blocks 21. The number and installation position of the counterweight blocks 21 can be adjusted, and the buoyancy of the inspection device in the water is adjusted by the cooperation between the buoyancy blocks 13 and the counterweight blocks 21. In actual use, the number of counterweight blocks 21 is adjusted so that the underwater robot provided by the present application has a slight positive buoyancy in the water as a whole, and the buoyancy does not exceed 200g.

By utilizing the electromagnetic induction phenomenon in physics, the coil 19 will generate current while cutting the magnetic flux lines.
