[0020] Example one: underwater cable protection of deep-sea oil exploitation platform

[0021] Application scenario:

[0022] Deep-sea oil exploitation platform needs stable and safe underwater cable connection to ensure data transmission and power supply. Due to the huge pressure of deep-sea environment and the corrosion problem, a high-performance shielding jacket is needed to protect the cable.

[0023] Specific use:

[0024] The shielding jacket is used to resist the high pressure and corrosive environment of the deep sea by using its outer pressure ring 11 and corrosion-resistant coating 12. The fixed anchor 23 in the fixing assembly 2 can firmly fix the jacket on the seabed, ensuring that the cable will not move due to water flow. The positioning assembly 3 adjusts the screw 34 and the extension column 32 to flexibly adjust according to the seabed topography, ensuring the stability of the jacket.

[0025] Example two: underwater cable protection of cross-sea bridge

[0026] Application scenario:

[0027] The underwater cable of a sea-crossing bridge needs to withstand the weight of the bridge, water flow impact, and potential threats such as ship anchors. Therefore, a shielding jacket is needed that can both protect the cable from physical damage and resist environmental erosion.

[0028] Specific use:

[0029] With this shielding jacket, the outer compression ring 11 and compression-resistant filling layer 14 are used to enhance the compression resistance of the jacket, resisting the weight of the bridge and water flow impact. The design of the flexible protection ring 15 allows the jacket to have some buffer and deformation space when subjected to external forces, thereby protecting the cable from damage. At the same time, the corrosion-resistant coating 12 and the fixing function of the positioning assembly 3 ensure that the jacket can maintain stability and protection performance in long-term use.

[0030] Example three: underwater communication base station cable protection

[0031] Application scenario:

[0032] Underwater communication base stations require stable underwater cable connections to transmit data. Since communication base stations are usually located in the sea far from land, cables need to withstand long-term marine environmental erosion and potential biological attachment problems.

The inner wall of shielding ring 13 is fixedly connected with compression-resistant filling layer 14, the inner wall of compression-resistant filling layer 14 is fixedly connected with flexible protection ring 15, the inner wall of flexible protection ring 15 is throughly provided with installation inner cavity 16, for installing underwater cable.

[0034] A plurality of fixed assembly 2 is uniformly fixed to the outer wall of protection jacket 1, each fixed assembly 2 includes a fixed ring 21, the inner wall of fixed ring 21 is throughly provided with fixed inner cavity 22, the inner diameter size of fixed inner cavity 22 matches the outer diameter size of protection jacket 1. The bottom of fixed ring 21 is uniformly fixedly connected with a plurality of fixed nails 23, which is used to fix the shielding jacket in the soil or rock under water.

[0035] The bottom of the protective sheath 1 is fixedly connected with a bottom fixing plate 17, and the bottom of the bottom fixing plate 17 is provided with a plane structure.

The bottom of the fixing column 31 is fixedly connected with an extension column 32, and the bottom of the extension column 32 is fixedly connected with a positioning anchor 33 for further fixing the position of the shielding sheath. The outer wall of one end of the fixing column 31 close to the extension column 32 is fixedly connected with an adjusting bolt 34 in a threaded manner, and the extension length of the extension column 32 can be adjusted through the adjusting bolt 34, so as to adapt to different water depths and terrain conditions.

[0036] The working principle of the utility model is: when it is needed to install the underwater cable underwater, firstly, the cable is passed through the installation inner cavity 16 of the protective sheath 1, and a plurality of fixing assemblies 2 and positioning assemblies 3 are fixed on the outer wall and the bottom of the protective sheath 1 respectively.
