[0047] In some embodiments, Figure 4 , Figure 5 and Figure 6 As shown, the fixed plate 21 is provided with supporting lugs 211 in pairs corresponding to the rotating plate 22, and a rotating shaft 212 is rotatably provided on the two supporting lugs 211 arranged in pairs. The rotating plate 22 is rotatably provided on the rotating shaft 212, and the distance between the rotating shaft 212 and the end of the rotating plate 22 close to the top plate 11 is greater than the distance between the rotating shaft 212 and the end of the rotating plate 22 away from the top plate 11.

[0048] By providing the supporting lug 211, the rotating plate 22 is connected to the supporting lug 211 via the rotating shaft 212, so as to facilitate the rotation adjustment of the rotating plate 22. Meanwhile, the connection position between the rotating shaft 212 and the rotating plate 22 is restricted, so as to ensure the effective adjustment angle of the end of the rotating plate 22 provided with the cleaning belt 23, thereby satisfying the cleaning effect of the submarine cable.

[0049] In some embodiments, Figure 4 , Figure 5 and Figure 6 As shown, the cleaning assembly 2 includes a pulley 25, a drive shaft 26, a drive motor 27, a first transmission belt 28, and a second transmission belt 29. The pulley 25 is arranged at the end of the rotating plate 22 away from the top plate 11, the drive shaft 26 is fixed to the pulley 25 and rotatably arranged on the rotating plate 22, the drive motor 27 is fixed to the fixed plate 21, the first transmission belt 28 is sleeved on the output end of the drive motor 27 and the rotating shaft 212, and the second transmission belt 29 is sleeved on the rotating shaft 212 and the drive shaft 26.

[0050] Specifically, the driving motor 27 is arranged in the fixed plate 21 or on a side of the fixed plate 21 close to the top plate 11. The output end of the driving motor 27 is fixedly connected to an extension rod, and the extension rod is rotatably arranged relative to the fixed plate 21. The supporting lug 211 is provided with a first groove for installing the first transmission belt 28. The end of the rotating plate 22 is provided with a mounting hole, and the driving shaft 26 is rotatably arranged on the mounting hole. The pulley 25 is fixedly arranged on the driving shaft 26.

At the same time, the first transmission belt 28 and the second transmission belt 29 are prevented from being interfered with by other objects, thereby ensuring the rotation operation of the cleaning belt 23.

[0051] In some embodiments, Figure 7 As shown, the spoiler assembly 3 includes a fixed box 33, a diverter pipe 34 and a pump body 35. The fixed box 33 is arranged in the working chamber and is fixedly connected to the top plate 11. The pump body 35 is arranged in the fixed box 33. The diverter pipe 34 is provided with multiple water outlets connected to the pump body 35. The first spoiler pipe 31 and the second spoiler pipe 32 are both connected to the diverter pipe 34.

[0052] Specifically, the water inlet of the pump body 35 is arranged on the front side of the shell 1, and a battery module electrically connected to the pump body 35 is arranged in the fixing box 33. The first spoiler pipe 31 and the second spoiler pipe 32 are respectively connected to the shunt pipe 34. The pump body 35 transports the extracted seawater to the first spoiler pipe 31 and the second spoiler pipe 32 through the shunt pipe 34 and discharges it through the ports of the first spoiler pipe 31 and the second spoiler pipe 32, thereby increasing the water flow in the working chamber and outside the shell 1 to transport the cleaned dirt to a position away from the submarine cable, thereby ensuring the cleaning effect of the submarine cable.

[0053] In some embodiments, Figure 7 As shown, the first spoiler pipe 31 is arranged perpendicular to the top plate 11, the second spoiler pipe 32 is arranged at an angle to the top plate 11, and the water outlet end of the second spoiler pipe 32 faces the rear end of the shell 1. By arranging the first spoiler pipe 31 perpendicular to the top plate 11, the first spoiler pipe 31 can ensure the stability of the shell 1 on the seabed through the reverse force of the water body when spraying seawater, so as to ensure that the cleaning belt 23 can be attached to the surface of the submarine cable, thereby ensuring the cleaning effect. At the same time, the second spoiler pipe 32 is inclined to provide power for the movement of the shell 1, and accelerate the discharge of the dirt cleaned in the working cavity, so as to avoid the cleaned impurities from falling vertically again and adhering to the surface of the submarine cable, thereby further ensuring the cleaning effect.

[0054] Optionally, the diameter of the second spoiler tube 32 is smaller than that of the first spoiler tube 31, and the jetting force of the second spoiler tube 32 is greater than that of the first spoiler tube 31, so that the seawater inside the shell 1 can be blown backward, thereby blowing the impurities cleaned in the working chamber backward.

[0055] In some embodiments, Figure 1 and Figure 2 As shown, it includes guide rollers 4, which are arranged in pairs at the front and rear sides of the fixing plate 21. The guide rollers 4 are provided with guide grooves 41, which are used to cooperate with the surface of the submarine cable.

[0056] In some embodiments, Figure 1 , Figure 2 and Figure 3 As shown, the cleaning belt 23 is provided with 231, and the direction of 231 is the same as the rotation direction of the cleaning belt 23. By providing 231, the cleaning efficiency of the cleaning belt 23 on the submarine cable can be increased, thereby ensuring the cleaning effect on the submarine cable.

[0057] In some embodiments, Figure 1 and Figure 2 As shown, the support portion 12 includes a support plate 121 and a power track 122 arranged on the support plate 121, and a plurality of protrusions 123 are arranged at intervals on the power track 122. The support plate 121 serves as a counterweight. The power track 122 is a track-type structure commonly used in the prior art, which is used to drive the protrusions 123 to move periodically. During this process, the protrusions 123 will move the mud and sand on the seabed, thereby giving the device as a whole a forward driving force. At the same time, the protrusions 123 can ensure that the device stays firmly on both sides of the submarine cable, reducing the impact of submarine currents.
