[0026] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0027] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0028] Figure 1 、 Figure 2 and Figure 3 The shown embodiment shows a high-toughness, cold-resistant submarine cable, comprising a core wire 1, an insulating layer 2 sheathed on the outside of the core wire 1, a water-blocking tape 3 sheathed on the outside of the insulating layer 2, a metal shielding layer 4 sheathed on the outside of the water-blocking tape 3, a PE sheath 5 sheathed on the outside of the metal shielding layer 4, a steel wire armor 6 sheathed on the outside of the PE sheath 5, a rubber sheath 7 extruded on each steel wire of the steel wire armor 6, an inner lining layer 8 sheathed on the outer surface of the rubber sheath 7, an asphalt layer 9 coated on the outer side of the inner lining layer 8, an outer sheath 10 sheathed on the outer side of the asphalt layer 9.

[0029] The insulating layer 2 is composed of a conductor shield 21 , an insulating layer 22 and an insulating shield 23 in sequence from the inside out.

[0030] In order to cooperate with external assembly and drive adjustment, an arc-shaped external assembly frame 12 is fixedly assembled on the outer surface of the outer layer 10 through a tightening hoop 11, and an angle-adjustable control impeller assembly 13 is movably assembled inside the arc-shaped external assembly frame 12.

[0031] The tightening hoop 11 is directly sleeved on the outside of the outer layer 10 and can be changed into an electrically controlled tightening hoop 11 as needed, so as to facilitate fixing and separation.

[0032] The angle-adjustable control impeller assembly 13 drives the water flow by rotating, thereby adjusting the posture of the submarine cable during the falling process, thereby avoiding pulling damage after collision.

[0033] In order to cooperate with lateral support and assembly, both sides of the tight hoop 11 are provided with outwardly extending arc-shaped support covers 14 on the assembly surface of the outer layer 10.

[0034] In order to accurately monitor the collision point, a pressure monitoring unit 15 is fixedly installed on the assembly surface of the arc-shaped support cover 14 and the outer layer 10.

[0035] Monitoring is performed by collision at different ends.

[0036] In order to control the flipping adjustment, the outer side surface of the arc-shaped support cover 14 is movably equipped with a lateral electric control support rod 16 for controlling the flipping of the arc-shaped external assembly frame 12.

[0037] The lateral electric control support rod 16 controls the arc-shaped external assembly frame 12 to perform flip adjustment by telescoping.

[0041] The embedded level controller 18 monitors the horizontal state of the submarine cable and then automatically controls the electronically controlled worm gear adjustment assembly 17 to change the angle of the adjustable angle control impeller assembly 13. In this way, the rotation direction of the impeller assembly 13 can be adjusted to adjust the posture of the submarine cable during descent and laying, and quick adjustments can be made in the event of a collision to avoid damage caused by squeezing.
