Description

Technical Field

[0001] The utility model relates to the field of submarine cable cleaning, in particular to a submarine cable cleaning device. Background Art

[0002] Submarine cable cleaning technology mainly refers to the technology used to remove dirt, seaweed, sediment and other impurities on the surface of submarine cables. These impurities may reduce the working efficiency of the cable and even affect the life of the cable.

[0003] A Chinese utility model patent with publication number CN216800846U discloses a submarine cable cleaning device, which relates to the field of cable cleaning technology. The cleaning device uses spraying and brushing to brush the surface of the submarine cable in transit, thereby removing oil and impurities on the surface of the submarine cable. However, since the brush is prone to accumulate dirt during the brushing process, the dirt on the brush cannot be removed by spraying alone. If not handled in time, it is easy to cause scratches on the surface of the submarine cable during the brushing process. Even a crack is easy to be eroded by seawater more quickly after the submarine cable is laid, forming a safety hazard. Regular cleaning will affect efficiency. Overall, the device is less practical and less safe.

[0004] Therefore, a submarine cable cleaning device is provided to solve the above problems. Utility Model Content

The ultrasonic generator 13 drives at least four ultrasonic vibrators 131 distributed in a rectangular array to vibrate at high frequency in the cleaning tank 11, and cavitation occurs in the water to disperse, emulsify and peel off the dirt layer, thereby achieving the purpose of cleaning. At the same time, when ultrasonic waves propagate in the liquid, they will cause the particles in the liquid to vibrate violently. This vibration will accelerate the molecular movement in the liquid, weaken the binding force between the dirt and the surface of the cleaning piece, and is conducive to the removal of the dirt. When ultrasonic waves propagate in the liquid, high-speed microjets will be generated on the surface of the cleaning piece. This microjet can directly flush the surface of the cleaning piece and peel off the dirt from the surface.
