Description

Technical Field

[0001] The utility model relates to the field of submarine cable laying auxiliary tools, in particular to a laying plough guide base. Background Art

[0002] During the submarine cable laying process, in order to ensure the safety and stability of the submarine cable on the seabed, a laying plow will be used to plow a trench on the seabed for placing the submarine cable, and the submarine cable will be laid along the trench.

[0003] The movement of the burying plow is mainly to pull the burying plow through the traction wire rope by the ship. In order to ensure that the submarine cable can be laid in the trench as soon as possible, the submarine cable will be laid directly along the blade arm of the burying plow, that is, the burying plow plows out the trench while guiding the laying of the submarine cable. Therefore, the submarine cable is always moving relative to the burying plow, while the traction wire rope is in a relatively static state relative to the burying plow, that is, with the ship as a reference, the submarine cable is relatively moving, and the traction wire rope is relatively static. The submarine cable and the traction wire rope extend from the ship to the burying plow at the same time. In the complex environment at sea, if there is no good guidance between the submarine cable and the traction wire rope, interference is likely to occur, which is not conducive to the laying of the submarine cable. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a laying plough guide base for guiding a submarine cable and a traction steel wire rope so as to avoid interference between the submarine cable and the traction steel wire rope during the laying process of the submarine cable.

[0005] The technical solution adopted by the utility model to solve the above-mentioned problem is: a laying plough guide base, including a guide seat, the guide seat is fixedly connected to the deck of the ship, the upper end of the guide seat is provided with a wire rope guide column for guiding the traction wire rope, the two ends of the traction wire rope are respectively connected to the ship and the laying plough, a submarine cable guide column for guiding the submarine cable is provided below the wire rope guide column, the wire rope guide column is fixedly connected to the guide seat, and the submarine cable guide column is rotatably connected to the guide seat.

[0006] Compared with the prior art, the utility model has the following advantages: in the process of traction of the burying plow by the traction wire rope, the traction wire rope is in a tensioned state, so that the traction wire rope is in a relatively stable use state, while the submarine cable is constantly moving and is not in a tensioned state. It will naturally sag on the deck and when it is detached from the deck. Therefore, through the design of the guide seat, the traction wire rope is guided at the upper end of the guide seat, and the submarine cable is guided below the traction wire rope. At this time, the two are layered up and down, and the traction wire rope is in a tensioned state, which will not interfere with the submarine cable below, and the sagging phenomenon of the submarine cable cannot affect the traction wire rope above the submarine cable. At the same time, because the two are not in the same horizontal plane, when the ship shakes, the two will not contact in the horizontal direction, thereby avoiding interference between the traction wire rope and the submarine cable on the deck. When leaving the deck, the traction wire rope is in a tensioned state, and the traction position of the traction wire rope can be fixed by designing the connection between the traction wire rope and the burying plough. The submarine cable is naturally drooping and then extended in the direction of the knife arm of the burying plough. It only needs to ensure that the traction position of the traction wire rope is always above the submarine cable, thereby avoiding interference between the traction wire rope and the submarine cable after leaving the deck, and ensuring the safety and stability of the burying plough when laying the submarine cable.

[0007] As an improvement of the present invention, the guide seat is composed of two fixed bases and a connecting seat, the two fixed bases are fixedly connected to the deck and are symmetrically distributed on the left and right, the connecting seat is fixedly connected to the upper ends of the two fixed bases, and the bottom ends of the two sides of the connecting seat are respectively fixedly connected to the two fixed bases, the wire rope guide column is fixedly connected to the connecting seat in the horizontal direction along the axis, and the two ends of the submarine cable guide column are respectively rotatably connected to the two fixed bases. Through the improvement, the molding of the guide seat is realized, and the upper and lower layered arrangement of the wire rope guide column and the submarine cable guide column is ensured, thereby ensuring the separability between the traction wire rope and the submarine cable during the laying process.

[0008] As an improvement of the utility model, a wire rope guide groove is provided on the central symmetric plane of the connecting seat, and the wire rope guide groove is arranged along the circumference of the wire rope guide column. The wire rope guide groove is used to limit the axial offset of the traction wire rope along the wire rope guide column. Through the improvement, the stability of the traction wire rope in the wire rope guide groove is guaranteed, and the traction wire rope is prevented from being detached during the traction buried plow process.

[0009] As an improvement of the utility model, anti-wear rings are provided at both ends of the wire rope guide groove. Through the improvement, because the traction wire rope is in a tensioned state, the ship will shake in a complex marine environment, and the traction wire rope will also swing left and right. The design of adding the anti-wear ring is to avoid wear between the traction wire rope and the connecting seat during the swinging process, which affects the safety of use.

[0010] As an improvement of the utility model, a submarine cable guide groove is further provided between the two fixed bases, and the submarine cable guide groove is arranged along the circumference of the submarine cable guide column. The submarine cable guide groove is used to limit the axial offset of the submarine cable along the submarine cable guide column. Through the improvement, the stability of the submarine cable in the submarine cable guide groove is ensured, and the space for the submarine cable to pass through the guide seat is increased, while also preventing the submarine cable from detaching during the laying process.

[0011] As an improvement of the present invention, the distance between the two ends of the connecting seat used to fix the connection of the wire rope guide column is smaller than the distance between the two ends of the two fixed bases used to rotatably connect the submarine cable guide column. Through the improvement, on the guide seat, the wire rope guide column is the main force point, which bears the steering force of the ship pulling the buried plow, while the submarine cable guide column only needs to bear the supporting force of the submarine cable. Therefore, the force on the wire rope guide column is much greater than the force on the submarine cable guide column, so that the guide seat forms a phenomenon of heavy upper end and light lower end. Through the design that the distance between the two ends of the connecting seat used to fix the connection of the wire rope guide column is smaller than the distance between the two ends of the two fixed bases used to rotatably connect the submarine cable guide column, the wire rope can be fixedly connected to the guide seat. The force of the wire rope guide column is transmitted in a balanced manner toward the fixed base. If the distance between the two ends of the connecting seat used to fix the wire rope guide column is greater than the distance between the two ends of the two fixed bases used to rotate and connect the submarine cable guide column, the fixed base is prone to cause instability in the connection between the fixed base and the deck due to the torque, or even damage. Similarly, if the distance between the two ends of the connecting seat used to fix the wire rope guide column is equal to the distance between the two ends of the two fixed bases used to rotate and connect the submarine cable guide column, when the traction wire rope swings left or right, uneven force is also likely to occur, causing the risk of instability in the connection between the fixed base and the deck, or even damage.

[0012] As an improvement of the present invention, the two sides of the connecting seat are arranged at an angle, and the bottom surface width of the connecting seat is equal to the top surface width of the two sides separated by the two fixed bases. Through the improvement, the comprehensiveness of the force transmission from the connecting seat to the fixed base is ensured, the uneven force on the fixed base is avoided, and the strength of the fixed base is fully utilized.

[0013] As an improvement of the present invention, the sides of the two fixed bases that are close to each other are vertically arranged, and the sides of the two fixed bases that are far away from each other are inclined. The bottom width of the fixed base is greater than the top width of the fixed base. Through the improvement, the supporting stability of the fixed base is increased.
