The machine body of the first servo motor is packaged in a waterproof structure. The machine body of the first servo motor is rotatably and sealingly connected to the output shaft. In order to enable the motor to be used in water, the output shaft also needs to be designed with a waterproof structure. The design of the waterproof structure can refer to the design of the connection between the propeller and the driving motor in a ship, which will not be described here.

[0046] The covering device is installed at the bottom of the machine body 2 and is used to cover the suspended cable 1.

[0047] One end of the conveying pipe 3 is connected to the machine body 2, and the other end is connected to the ship body, which is used to convey the covering material. In this embodiment, the covering material can be stone or solidified soil. The conveying pipe 3 is a flexible hose. The stone or solidified soil enters from the end of the conveying pipe 3 located on the ship body and flows out from the machine body 2, thereby achieving the covering of the cable 1. A screw conveyor or a feeding conveying mechanism is arranged on the ship body and is used to convey the stone or solidified soil. The conveying pipe 3 is connected to the discharge port of the conveying mechanism. When the walking device contacts the ground, the end of the conveying pipe 3 located on the ship body has an excess amount. When the walking device moves along the cable 1, the excess amount can be synchronously fed into the water. In this embodiment, as shown in Figure 1 and 2 A rear camera is arranged on the right side of the machine body 2 and is used to take real-time photos of the feeding effect of the covering material, so as to facilitate the subsequent reinforcement of the cable 1 in the part with an unsatisfactory covering effect. The size of the stone or the viscosity of the solidified soil is large enough and will not be washed away by the water flow.

[0048] The walking device is installed at the bottom end of the machine body 2 and is located on both sides of the covering device. The walking device provides moving power for the treatment device after contacting the ground.

Figure 1, the through holes and the electromagnetic switch valves are one-to-one corresponding, and are located at the bottom end of the buoyancy bin 201. When the buoyancy bin 201 needs to be filled with water and sink, the plugging head on the first gas pipe fork of the gas pipe is removed, and the electromagnetic switch valve is opened, so that water can enter the buoyancy bin 201, and the treatment device can sink; when the buoyancy bin 201 needs to be drained and float, the plugging head blocks the first gas pipe fork of the gas pipe, and the air compressor is started, the air compressor produces gas to expel the water in the buoyancy bin 201, the treatment device gradually floats, and the electromagnetic switch valve is closed after the water in the buoyancy bin 201 is completely drained. Similar to the conveying pipe 3, the gas pipe also has a surplus at one end of the ship body. In order to prevent the gas pipe and the conveying pipe 3 from being entangled with each other in the water, the two can be tied together in advance before use. In this embodiment, the treatment device can move flexibly in the horizontal direction and the vertical direction through the cooperation of the first propulsion unit and the second propulsion unit, so as to realize accurate positioning and effective treatment of the suspended submarine cable. The covering device is installed at the bottom of the machine body 2, can closely fit the suspended cable 1, and provides stable covering effect, which helps to fix the suspended cable 1 and prevent it from being further suspended or damaged due to water flow erosion or other external forces.
