The second slide bar 754 has a first preset size in the first direction, and a sliding ring 792 is provided on the second slide bar 754 to be slidably connected thereto. A plurality of first rotating rods 756 are connected to the sliding rings 792 on the plurality of nozzles 757 in a one-to-one correspondence, and one end of the first rotating rod 756 adjacent to the second end 712 in the first direction is hinged to the first sliding plate 755, and one end of the first rotating rod 756 away from the second end 712 in the first direction is hinged to the sliding ring 792, and the first sliding plate 755 slides in the first direction to drive the nozzle 757 to rotate.

[0074] The mobile driver 74 is a second driving rod, the axial direction of the second driving rod is the first direction, the telescopic portion of the second driving rod can extend outward in the first direction in a direction away from the second end 712, the second driving rod is located between the first sliding plate 755 and the second end 712 in the first direction, and the telescopic portion of the second driving rod is connected to the first sliding plate 755 so as to drive the first sliding plate 755 to move in the first direction. For example, the axial direction of the second driving rod is the front-to-back direction, the telescopic portion of the second driving rod can extend backward, the second driving rod is located between the first sliding plate 755 and the second end 712 in the front-to-back direction, and the telescopic portion of the second driving rod is connected to the first sliding plate 755 so as to drive the first sliding plate 755 to move in the front-to-back direction. The backward movement of the first sliding plate 755 can drive the nozzle 757 to rotate downward and can drive the sand suction pipe 791 to rotate.

[0075] When the mobile driver 74 is extended, it will push the first sliding plate 755 to slide backward on the surface of the first sliding frame 758. Under the action of the first rotating rod 756, the second sliding rod 754 is pushed, so that the second sliding rod 754 pushes the multi-head high-pressure nozzle 757 to drive the first rotating shaft 752 to rotate in the inner cavity of the first bottom plate 751, that is, the multi-head high-pressure nozzle 757 rotates to a suitable position with the first rotating shaft 752 as the center of the circle, and the first sliding plate 755 slides backward while also pushing the gear plate 78. With the cooperation of the gear 79, the sand suction pipe 791 is driven to rotate to a suitable position. The high-pressure water flow generated by the high-pressure water pump 2 enters the two multi-head high-pressure nozzles 757 through the high-pressure hose 753. The cable is located between the two multi-head high-pressure nozzles 757. The high-pressure water flow is used by the multi-head high-pressure nozzles 757 to flush away the mud and sand to form a groove, and the cable falls into the groove, finally completing the cable laying work.

[0076] When the submarine cable burying device according to the embodiment of the present invention needs to lay the submarine cable, the device is taken out from the cable laying ship, and the device is lifted to a suitable position in the sea by the lifting mechanism on the cable laying ship in cooperation with the connection group 6. The connection group 6 enables the staff on the cable laying ship to control the device to move on the seabed and find the submarine cable so that the submarine cable is located between the sand discharge mechanisms 7. After adjusting its position, the sand discharge mechanism 7 generates a high-pressure water flow through the high-pressure water pump 2 to flush the mud and sand to form a groove of appropriate depth. The cable between the sand discharge mechanisms 7 will fall into the bottom of the groove. The device runs along the submarine cable while flushing the mud and sand until the work is completed. After the laying is completed, the lifting group 5 is started to lift the device from the seabed upwards, and the device is lifted back to the cable laying ship by cooperating with the lifting mechanism on the cable laying ship. Through the cooperation of the chuck 62 and the lifting mechanism on the cable laying vessel, the lifting operation of the device can be completed quickly. The lifting ear 63 can prevent the chuck from being damaged and unable to perform the lifting operation. At the same time, through the coordinated use of the visual component 65, the controller 66 and the antenna 64, the staff can remotely control the device on the seabed to lay the cable.

[0077] Therefore, the submarine cable burying device according to the embodiment of the present invention has the advantages of being easy to lift and easy to discharge sand.
