Description

Technical Field

[0001] This utility model belongs to the field of submarine cable laying technology, specifically relating to a submarine cable laying traction device. Background Technology

[0002] During the laying of submarine cables (referred to as "submarine cables"), the submarine cables must be accurately laid to the predetermined seabed position, while avoiding problems such as displacement, twisting, and excessive friction caused by water flow impact, terrain undulations, or improper traction operations.

[0003] Traditional submarine cable laying methods often rely on simple floats for buoyancy adjustment or extensive traction using tugboats or shore-based equipment, which have the following limitations:

[0004] Insufficient position control precision: Traditional floats can only provide basic buoyancy and cannot achieve precise adjustment of the submarine cable in the vertical (depth) and horizontal directions. The submarine cable is prone to deviating from the preset path due to changes in water flow and tides.

[0005] The adjustment method is passive: the existing traction device lacks an active adjustment structure. When the submarine cable needs to be raised or lowered (such as to avoid obstacles in shallow waters) or moved horizontally (such as to correct the laying trajectory), it needs to rely on external equipment (such as towing by a tugboat). The operation is complicated and the response is slow, making it difficult to adapt to complex sea conditions. Utility Model Content

[0006] The purpose of this invention is to provide a submarine cable laying traction device that can simply and effectively control the position of the submarine cable in seawater during the laying process.

[0007] The specific technical solution adopted by this utility model is as follows:

[0008] A submarine cable laying traction device includes a submarine cable float, wherein a partition is fixedly connected inside the submarine cable float, and the partition divides the internal space of the submarine cable float into an equipment cavity and a water pressure regulating chamber.

[0009] The submarine cable buoy is equipped with:

[0010] The pressure chamber adjustment mechanism is located inside the submarine cable float and is used to adjust the buoyancy of the pressure chamber, thereby driving the submarine cable float to move vertically up and down in the seawater.

[0011] A horizontally movable structure is installed on the outside of the submarine cable float to drive the submarine cable float to move horizontally in the seawater.

[0012] The electric clamp is fixedly connected to the underside of the submarine cable float and is used to clamp and fix the submarine cable.

[0013] The storage battery is fixedly connected inside the equipment cavity;

[0014] The controller is fixedly connected inside the equipment cavity, and the water pressure chamber adjustment mechanism, horizontal movement structure, electric clamp and battery are all electrically connected to the controller.

[0015] Furthermore, the water pressure chamber adjustment mechanism includes a baffle plate and a lifting mechanism. The baffle plate is vertically slidably connected inside the water pressure adjustment chamber. The space inside the water pressure adjustment chamber located above the baffle plate is a hollow buoyancy cavity, and the space inside the water pressure adjustment chamber located below the baffle plate is a water storage cavity. A water passage hole connected to the water storage cavity is opened at the lower part of the periphery of the submarine cable float.

[0016] The lifting mechanism is fixedly connected inside the submarine cable float, and the lifting mechanism and the water-proof plate are connected by a transmission.

[0017] Furthermore, the lifting mechanism includes a drive motor fixedly connected inside the equipment cavity, and the output end of the drive motor is driven by a screw rotatably connected inside the water pressure regulating chamber. The screw is threadedly connected to the water baffle plate.

[0028] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0029] like Figures 1-4 As shown, a submarine cable laying traction device includes a submarine cable float 1. The submarine cable float 1 is equipped with a pressure chamber adjustment mechanism, a controller 3, a horizontal movement structure, an electric clamp, and a battery. The pressure chamber adjustment mechanism, the horizontal movement structure, the electric clamp, and the battery are all electrically connected to the controller 3.

[0030] like Figures 2-4 As shown, in some embodiments, a partition 2 is fixedly connected inside the submarine cable float 1. The partition 2 divides the space inside the submarine cable float 1 into an equipment cavity and a water pressure regulating chamber. The water pressure regulating mechanism is set inside the submarine cable float 1 to regulate the buoyancy of the water pressure regulating chamber, thereby driving the submarine cable float 1 to move vertically up and down in the seawater and adjusting the height of the submarine cable laying traction device.

[0031] The water pressure chamber regulating mechanism includes a baffle plate 6 and a lifting mechanism. The baffle plate 6 is vertically slidably connected inside the water pressure regulating chamber, and a sealing ring with an interference fit to the inner wall of the water pressure regulating chamber is fixedly connected to the periphery of the baffle plate 6 to ensure sealing. The space above the baffle plate 6 inside the water pressure regulating chamber is a hollow buoyancy cavity, and the space below the baffle plate 6 inside the water pressure regulating chamber is a water storage cavity. A water passage hole 9 connected to the water storage cavity is opened at the lower part of the periphery of the submarine cable float 1. Water can enter or exit the water storage cavity through the water passage hole 9.

[0032] The lifting mechanism is fixedly connected inside the submarine cable float 1. The lifting mechanism and the water-proof plate 6 are connected by transmission and are used to drive the water-proof plate 6 to move up and down, thereby adjusting the spatial dimensions of the water storage cavity and the hollow buoyancy cavity, changing the buoyancy of the submarine cable laying traction device, and realizing the vertical lifting and lowering movement of the submarine cable laying traction device in seawater.

[0033] Specifically, the lifting mechanism includes a drive motor 4 fixedly connected inside the equipment cavity. The output end of the drive motor 4 is driven by a screw 5 rotatably connected inside the water pressure regulating chamber. The screw 5 and the baffle plate 6 are threadedly connected. The drive motor 4 drives the baffle plate 6 to rotate, which in turn drives the baffle plate 6 to rise and fall.

[0034] The horizontal moving structure is installed on the outside of the submarine cable float 1 to drive the submarine cable float 1 to move horizontally in the seawater and adjust the horizontal position of the cable laying traction device.

[0035] like Figure 1 The horizontal movement structure includes multiple angle adjustment mechanisms 7 fixedly connected to the outside of the submarine cable float 1. The angle adjustment mechanism 7 can be an electric turntable or a servo motor. A propeller 8 is fixedly connected to the lower side of the angle adjustment mechanism 7. At this time, the direction of the propeller 8 can be adjusted by adjusting the angle adjustment mechanism 7, and then the propeller 8 can be started to push the submarine cable float 1 to move horizontally in the seawater.

[0036] Among them, the electric clamp is fixedly connected to the lower side of the submarine cable float 1 and is used to clamp and fix the submarine cable.

[0037] like Figures 2-4 As shown, in some embodiments, the electric clamp includes a U-shaped frame 10 fixedly connected to the lower side of the submarine cable float 1. Electric telescopic rods 11 are fixedly connected to both sides of the U-shaped frame 10. Two clamping plates 12 are slidably connected inside the U-shaped frame 10. The piston rods of the two electric telescopic rods 11 are fixedly connected to the two clamping plates 12 respectively. At this time, by starting the electric telescopic rods 11, the clamping plates 12 can be moved to adjust the distance between the two clamping plates 12. The submarine cable can be placed between the two clamping plates 12 and clamped by the clamping plates 12.

[0038] A reinforcing rod 13 can also be fixedly connected to the clamp 12. The reinforcing rod 13 and the U-shaped frame 10 are slidably connected to each other and are used to reinforce the arc groove 14.

[0039] An arc-shaped groove 14 can be provided on one side of the two clamping plates 12 to limit the submarine cable located between the two clamping plates 12.

[0040] The controller 3 is fixedly connected inside the equipment cavity. The drive motor 4, angle adjustment mechanism 7, propeller thruster 8, and electric telescopic rod 11 are all electrically connected to the controller 3. The controller 3 is used to control the water pressure chamber adjustment mechanism, the horizontal movement structure, and the electric clamp.

[0041] In some implementations, the controller 3 includes a microcontroller that stores a control strategy, which controls the hydraulic pressure chamber adjustment mechanism, the horizontal movement structure, and the electric clamp.

[0042] In other embodiments, the controller 3 includes a PCB board, a GPS locator, and a communication module. In use, the GPS locator determines the position of the submarine cable laying traction device, and then the communication module feeds back the information to the ground host. The ground host sends a control signal to the communication module to control the submarine cable laying traction device to move to the corresponding position, thereby achieving adjustment of the submarine cable position in seawater.

[0043] The battery is fixedly connected inside the equipment cavity to provide electrical energy.

[0044] The working principle of this utility model is as follows:

[0045] When laying submarine cables, select several points on the submarine cable as nodes, and use electric clamps to clamp several submarine cable laying traction devices on the outside of the nodes in sequence, and then unwind the submarine cable into the sea.

[0046] When the submarine cable enters the seawater, it can be moved horizontally and vertically by activating the submarine cable laying traction device. The cable nodes can be moved by the submarine cable laying traction device. By sequentially moving several nodes of the submarine cable by several submarine cable laying traction devices, the position of the submarine cable in the seawater can be simply and effectively controlled during the laying process.

[0047] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
