Description

Technical Field

[0001] This utility model belongs to the field of submarine cable protection pipes, and specifically relates to a submarine cable pipeline current stabilization protection pipe. Background Technology

[0002] Submarine cables are laid on the seabed for telecommunications transmission. Because submarine cables operate on the seabed for a long time, but the seabed is not convenient for manual work, and it is quite troublesome to repair them once they are damaged, so cable protection plays a crucial role, hence the existence of submarine cable protection pipes.

[0003] Traditional submarine cable protection pipes typically have a two-part structure, with the two parts joined together for fixation. This type of pipe lacks a current-stabilizing structure and is easily affected by undersea turbulence. In addition, it has many components, making construction relatively complicated. Utility Model Content

[0004] This utility model provides a current stabilization protection pipe for submarine cable pipelines, which can solve the problems pointed out in the background art.

[0005] A current-stabilizing protection pipe for submarine cable pipelines includes a protection pipe body, characterized in that: a plurality of current-stabilizing fins extending along the length direction are provided on the circumferential surface of the protection pipe body, and the current-stabilizing fins are protruding to facilitate embedding into the seabed.

[0006] Preferably, the cross-section of the current-stabilizing fin is triangular.

[0007] Preferably, several flow-stabilizing fins are arranged in a spiral.

[0008] Preferably, the protective tube body includes at least two unit arcs, which are movably connected to each other, so that the protective tube body can be opened and closed, and is fixedly sleeved on the submarine cable by fasteners.

[0009] Preferably, the protective tube body is a thermoplastic elastomer material protective tube body, which is integrally molded. The movable connecting end of the unit arc body is provided with a plurality of connecting pieces along its length direction, and the thickness of the connecting pieces gradually decreases from the inner end to the movable connecting end.

[0010] Preferably, the connecting piece is triangular.

[0011] Preferably, the fixing member is a fixing cable tie or a fixing steel strip, and the protective tube body is provided with a limiting ring groove that cooperates with the fixing member.

[0012] Beneficial effects: This utility model provides a current stabilization protection pipe for submarine cable pipelines, which is equipped with current stabilization fins, making it easy to embed into the seabed, thereby increasing the overall stability and reducing the impact of seabed turbulence;

[0013] The protective tube body is made of thermoplastic elastomer material and is molded as a whole. The unit arcs are movably connected. The unit arcs can be pried open to both sides and fitted onto the submarine cable. Installation can be completed by fixing with fasteners, which is convenient. Attached Figure Description

[0018] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0019] Example 1:

[0020] like Figure 1-2 As shown, a current-stabilizing protection pipe for submarine cable pipelines includes a protection pipe body 1, characterized in that: a plurality of current-stabilizing fins 2 extending along the length direction are provided on the circumferential surface of the protection pipe body 1, and the current-stabilizing fins 2 are protruding to facilitate embedding into the seabed.

[0021] Specifically, the cross-section of the flow stabilizing fin 2 is triangular, and several flow stabilizing fins 2 are spirally arranged.

[0022] Example 2:

[0023] Special combination Figure 2 As shown, the protective tube body 1 includes at least two unit arc bodies 11, which are movably connected to each other, so that the protective tube body 1 can be opened and closed, and is fixedly sleeved on the submarine cable 3 by the fastener 13.

[0024] Specifically, the protective tube body 1 is a thermoplastic elastomer material protective tube body, such as TPU. The thermoplastic elastomer material protective tube body is integrally molded. Several connecting pieces 12 are provided on the movable connecting end of the unit arc body 11 along its length direction. The thickness of the connecting piece 12 gradually decreases from the inner end to the movable connecting end, that is, the thickness at the movable connection is thinner, so that the unit arc bodies 11 can be movably connected.

[0025] The connecting piece 12 is triangular, the fixing member 13 is a fixing cable tie or a fixing steel strip, and the protective tube body 1 is provided with a limiting ring groove 14 that cooperates with the fixing member 13.
