DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments only constitute some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. Specific embodiment one

[0026] Please refer to Figures 1-4This utility model relates to an armored cable for underwater use, comprising a protective component 1, a filling core 2, and a reinforcing component 3. The protective component 1 includes an outer protective sleeve 104, which protects the filling core 2. The reinforcing component 3 is provided around the outer protective sleeve 104, and reinforces the outer side of the outer protective sleeve 104. The reinforcing component 3 includes a fixing disc 301 and a reinforcing plate 303. When the reinforcing component 3 is in operation, it increases the bonding strength between the cable and the underwater covering material. The fixing discs 301 are fixed at equal intervals around the outer protective sleeve 104, which increases the bonding strength between the outer protective sleeve 104 and the underwater covering material along the length direction. Reinforcing plates 303 are fixed in a circular array between adjacent fixing discs 301, which increases the radial bonding strength between the outer protective sleeve 104 and the underwater covering material. This ensures that the cable is well confined in the filler at the bottom of the water during operation. The filling core 2 is provided inside the protective component 1, and the conductor is fixed therein.

[0027] Specifically, the protection component 1 further includes a filling layer 103 and a shielding copper sleeve 101. The filling layer 103 is fixed on the inner wall of the outer protective sleeve 104, and the shielding copper sleeve 101 is fixed on the inner wall of the filling layer 103. When the protection component 1 is working, the shielding copper sleeve 101 and the outer protective sleeve 104 are connected through the filling layer 103. During operation, electromagnetic shielding is provided through the shielding copper sleeve 101.

[0028] Furthermore, the protection component 1 also includes a protective armor 102, which is disposed between the outer protective sleeve 104 and the shielding copper sleeve 101. The protective armor 102 is spirally arranged and fixed inside the filling layer 103. When the protective armor 102 is in operation, it increases the strength of the cable. By fixing the protective armor 102 inside the filling layer 103, it reduces the friction between two adjacent spirals during the movement of the armor, and prevents damage to the outer protective sleeve 104 caused by friction between two adjacent spirals.

[0029] Furthermore, the filling core 2 is fixed inside the shielding copper sleeve 101. A fixing hole 202 is provided inside the filling core 2 along the central axis. An inner reinforcing strip 204 is fixed through the fixing hole 202. When the filling core 2 is working, the fixing hole 202 in the center fixes the inner reinforcing strip 204, thereby increasing the tensile strength of the cable in the length direction.

[0030] Furthermore, the inner core 2 outside the fixing hole 202 is uniformly provided with wire holes 201, and each wire hole 201 is fixed with a power transmission wire 203. The inner core 2 fixes the power transmission wire 203 through the wire holes 201, and the power transmission operation is carried out through the power transmission wire 203.

[0031] The operation process of the embodiment is as follows: during the operation, the cable is bent during the transportation, and the two spirals of the protective armor 102 rub against each other during the bending, straightening and other operations. When the two spirals of the protective armor 102 rub against each other, the protective armor 102 is limited by the filler layer 103 to be between the shielding copper sleeve 101 and the outer protective sleeve 104, and the outer protective sleeve 104 is not abraded due to the friction, thereby increasing the stability of the cable during transportation, laying and other operations. The power transmission conductor 203 in the filler inner core 2 is used for power transmission, and the inner reinforcing strip 204 is used for increasing the tensile strength of the cable.

When the reinforcing assembly 3 works, the torsional resistance of the cable is increased by the connecting rod 302.

[0034] The operation process of the embodiment is as follows: during the operation, the cable is bent during the transportation, and the two spirals of the protective armor 102 rub against each other during the bending, straightening and other operations. When the two spirals of the protective armor 102 rub against each other, the protective armor 102 is limited by the filler layer 103 to be between the shielding copper sleeve 101 and the outer protective sleeve 104, and the outer protective sleeve 104 is not abraded due to the friction, thereby increasing the stability of the cable during transportation, laying and other operations. The power transmission conductor 203 in the filler inner core 2 is used for power transmission, and the inner reinforcing strip 204 is used for increasing the tensile strength of the cable.
