Description

Technical field:

[0002] The invention relates to the field of submarine cables, in particular to a submarine cable laying device. Background technology:

[0004] Submarine cables are cables wrapped in insulating materials, laid on the seabed, and used for telecommunication transmission. Submarine cables are divided into submarine communication cables and submarine power cables. Modern submarine cables are made of optical fiber to transmit telephone and Internet signals. Submarine cables are divided into submarine communication cables and submarine power cables. Submarine communication cables are mainly used for communication services, which are expensive but highly confidential. Submarine power cables are mainly used to transmit high-power electrical energy underwater, which is equivalent to the function of underground power cables, except that they are used in different occasions and laid in different ways.

[0005] With the continuous advancement of science and technology, submarine cables are also widely used. The laying of submarine cables is the most complicated and difficult to operate. Unlike ordinary cables, grooves need to be cut on the seabed to facilitate cable laying. During the laying process, the operation is cumbersome and special equipment is required to cut grooves on the seabed before the cables can be laid. After the seabed is grooved, due to the influence of waves and seabed currents, a large amount of gravel and mud will flow into the groove, which is not only inconvenient for the subsequent laying, but also affects the quality of laying.

[0026] The roller shaft 21 is welded to the first guiding frame 5 and the second guiding frame 6, and the roller 20 is movably connected to the roller shaft 21.

[0027] A dredging groove is provided at the bottom of the device body 1. Both the first mud guide plate 9 and the second mud guide plate 16 are made of 304 stainless steel. The connecting rod 2 is welded to the outer shell of the device body 1.

[0028] A cable 4 is inserted through the first dredging frame 5 and the second dredging frame 6. The propeller motor 14 is fixed to the device body 1 by bolts. The cable protection plate 17 is welded to the outer shell at one end of the device body 1.

[0029] The drill bit braking motor 24 is fixed to the motor fixing plate 7 by bolts. A drill bit is welded to one end of the rotating rod 8. Both the crawler braking motor 19 and the roller braking motor 18 are fixed inside the device body 1.

[0030] A power cord is fixed to the connecting chain 3. The power cord is electrically connected to the control system of the device body 1. The control system is electrically connected to the propeller motor 14, the roller braking motor 18, the crawler braking motor 19, and the drill bit braking motor 24 respectively.

[0031] Working principle: A submarine cable laying device includes a device body 1, a connecting rod 2, a connecting chain 3, a cable 4, a first dredging frame 5, a second dredging frame 6, a motor fixing plate 7, a rotating rod 8, a first mud guide plate 9, a roller fixing frame 10, a roller 11, a roller rotating shaft 12, a crawler 13, a propeller motor 14, a propeller 15, a second mud guide plate 16, a cable protection plate 17, a roller braking motor 18, a crawler braking motor 19, a roller 20, a roller shaft 21, a bucket 22, a fixed steel plate 23, and a drill bit braking motor 24. When in use, the device body 1 is put into the seabed, and the propeller motor 14 drives the propeller 15 to rotate, so that the device body 1 stays on the laying groove on the seabed. The cable 4 passes through the first dredging frame 5 and the second dredging frame 6 and is movably connected to the dredging groove at the bottom of the device body 1. The roller braking motor 18 and the crawler braking motor 19 are braked, so as to drive the roller 11 and the crawler 13 to brake, so that the device body 1 moves on the laying groove. The bucket 22 at the bottom of the motor fixing plate 7 can dig out the sediment in the laying groove. The drill bit braking motor 24 drives the rotating rod 8 to rotate, so that the rotating rod 8 drives the fixed steel plate 23 to rotate, and the sediment is thrown to one side of the laying groove. When encountering a large stone, it can be processed by the drill bit at one end of the rotating rod 8. The thrown sediment is conveyed to one side of the device through the first mud guide plate 9. When laying the submarine cable, the second mud guide plate 16 guides the sediment on both sides into the laying groove to cover the cable, fix the cable, and also protect the cable.

[0032] This device can carry out sediment treatment on the submarine cable trench while laying the submarine cable. It not only makes the laying of the submarine cable more uniform, enables the submarine cable to be laid in a straight line in the submarine pre-buried trench, but also can cover and protect the laid cable with sediment to prevent the flow of seawater on the seabed from causing the laid cable to deviate from the laying trench. Moreover, it is also convenient to fix the cable, solving the problems of the traditional laying method, with high efficiency and fast speed. And through the simultaneous braking of the crawler and the tire, the stability of the device on the seabed is increased. One end of the device is also provided with a drill bit and a bucket, which can clean the sediment and some gravel in the submarine laying trench to ensure the safe and effective laying of the submarine cable.

It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
