A high-pressure water pump 18 is installed on the top side of the support plate 17, and the output end of the high-pressure water pump 18 is connected to a water pipe 19;

[0025] The top side of the other end of the laying vehicle body 1 is connected to a U-shaped rod 20, and a rope 21 is symmetrically installed on the outer wall of the U-shaped rod 20, and one end of the rope 21 is connected to the external hull;

[0026] One end of the bottom side of the paving vehicle body 1 is symmetrically fixed with two bottom plates 1 22, and the other end of the bottom side of the paving vehicle body 1 is fixed with a bottom plate 2 23;

[0027] The waterproof switch 15 is electrically connected to the cylinder 3 and the controller in the hull, wherein the controller is used for signal transmission of the waterproof switch 15 and operation control of the cylinder 3; during operation, in actual application, it is impossible to control the depth of the groove opened when burying the cable. If the groove depth is too shallow, the cable will be more easily exposed to the seabed surface due to the impact of waves, thereby increasing the probability of cable damage, which will affect the normal transmission function of the cable. Before the laying vehicle body 1 is launched, according to the requirements of cable burial, the pressing depth of the slotting plow 10 is determined by adjusting the limit ring 12 on the scale rod 11. After adjustment, the limit ring 12 is fixed to the scale rod 11 using the locking screw 13, and then the laying vehicle body 1 is connected to the external hull through the rope 21, and the laying vehicle body 1 is placed in the sea, and its bottom plate 1 22 and bottom plate 2 23 are in contact with the seabed, which increases the contact area between the laying vehicle body 1 and the seabed and improves the laying vehicle on the seabed. Stability during movement, the hull drags the laying vehicle body 1 to move on the seabed to perform cable laying operations. During the movement of the laying vehicle body 1 on the seabed, the high-pressure water pump 18 on the top side of the support plate 17 is started, and the high-pressure water pump 18 sprays water through the water pipe 19 to pre-open a trench on the seabed in front of the slotting plow 10 to prepare for cable laying. When the laying vehicle body 1 moves on the seabed, the active end of the cylinder 3 pushes the mounting plate 4 downward, and the mounting plate 4 drives the push rod 5 and the guide rod 6 to move downward. The guide rod 6 slides downward along the fixed plate 8, so that the connecting plate 9 drives the slotting plow 10 to press down, opening a trench for cable laying on the seabed. When the mounting plate 4 drops to a certain level, the push rod 5 will press the waterproof switch 15, and the waterproof switch 15 sends a signal to the controller. The controller controls the cylinder 3 to stop pressing down, thereby accurately controlling the depth of the slotting plow 10 to ensure the accuracy of the cable burial depth and the effect of cable laying.

[0028] See also Figure 1 、 2As shown in Figure 5, the other end of the guide tube 7 is symmetrically fixed with two mounting cavities 24. A rotating shaft 25 is rotatably installed inside the mounting cavity 24. Eight toggle plates 26 are installed on the outer wall of one end of the rotating shaft 25. A driven bevel gear 27 is installed at the other end of the rotating shaft 25. A support frame 28 is installed on the top side of the mounting cavity 24. A rotating shaft 29 is rotatably installed inside the support frame 28 and extends to the inside of the mounting cavity 24.

Eight fan blades 31 are equidistantly installed on the top of the rotating shaft 29. One end of the support frame 28 A water inlet 32 ​​is provided between the two sides; when working, the submarine cable is a cable wrapped with insulating material, laid on the seabed for telecommunication transmission, so a cable laying device is required. After laying, the cable needs to be buried. When the laying vehicle body 1 moves on the seabed, seawater flows into the water inlet 32, and the flow of seawater drives the fan blades 31 to rotate. The fan blades 31 drive the active bevel gear 30 to rotate through the rotating shaft 29. The active bevel gear 30 and the driven bevel gear 27 engage with each other, thereby driving the rotating shaft 25 to rotate. The eight toggle plates 26 on the outer wall of one end of the rotating shaft 25 rotate accordingly, and the cables laid in the ditch are quickly and evenly buried in the seabed, ensuring the burial quality.

[0029] Working principle: Before the laying vehicle body 1 is launched into the water, the pressing depth of the slotting plow 10 is determined by adjusting the limit ring 12 on the scale rod 11 according to the requirements of cable burial. After adjustment, the limit ring 12 is fixed to the scale rod 11 using the locking screw 13. Then, the laying vehicle body 1 is connected to the external hull through the rope 21, and the laying vehicle body 1 is put into the sea, and its bottom plate 1 22 and bottom plate 2 23 are in contact with the seabed, which increases the contact area between the laying vehicle body 1 and the seabed and improves the stability of the laying vehicle when moving on the seabed. The hull drags the laying vehicle body 1 to move on the seabed to perform cable laying operations. During the movement of the laying vehicle body 1 on the seabed, the high-pressure water pump 18 on the top side of the support plate 17 is started, and the high-pressure water pump 18 sprays water through the water pipe 19 to pre-open a trench on the seabed in front of the slotting plow 10 to prepare for laying the cable. When the laying vehicle body 1 moves on the seabed, the active end of the cylinder 3 pushes the mounting plate 4 downward, and the mounting plate 4 drives the push rod 5 and the guide rod 6 to move downward. The guide rod 6 slides downward along the fixing plate 8, so that the connecting plate 9 drives the slotting plow 10 to press down, and a trench for laying the cable is opened on the seabed. When the mounting plate 4 drops to a certain level, the push rod 5 presses the waterproof switch 15, and the waterproof switch 15 sends a signal to the controller, and the controller controls the cylinder 3 to stop pressing down, thereby accurately controlling the depth of the slotting plow 10 to ensure the accuracy of the cable burial depth and the effect of cable laying.

[0030] When the laying vehicle body 1 moves on the seabed, seawater flows in through the water inlet 32, and the flow of seawater drives the fan blades 31 to rotate. The fan blades 31 drive the active bevel gear 30 to rotate through the rotating shaft 29. The active bevel gear 30 and the driven bevel gear 27 engage with each other, thereby driving the rotating shaft 25 to rotate. The eight toggle plates 26 on the outer wall of one end of the rotating shaft 25 rotate accordingly, and the cables laid in the ditch are quickly and evenly buried in the seabed, ensuring the burial quality.
