[0022] 1. Basic structure and function

[0023] like Figures 1 to 6 As shown, the submarine cable protection device of the utility model includes a protection module 1, a clamping module 2 and a protective layer module 3. The clamping module can clamp and fix submarine cables of different diameters, playing a role in buffering and resisting the impact force and disturbance of seawater. In this way, the audience range of the device for submarine cables is expanded, and the problem that the existing submarine cables are relatively small in diameter and the protective equipment cannot clamp the submarine cables and cannot provide substantial protection is overcome. The protective layer module can protect the protection module.

[0024] The protection module is mainly composed of an upper semi-arc shell 102 and a lower semi-arc shell 101, wherein one end of the upper semi-arc shell and the lower semi-arc shell are hinged and the other end is plugged in; the front surfaces of the upper semi-arc shell and the lower semi-arc shell are both provided with a special-shaped groove 103, and a magnetic attraction layer 104 is provided on the special-shaped groove and the first arc plate, and the first arc plate is magnetically snapped into the special-shaped groove. A first connecting block 106 is fixedly connected to the other end of the lower semi-arc shell, a first connecting spring 109 is fixedly connected to the inner side surface of the first connecting block, and a plug block 110 is fixedly connected to the one side surface of the first connecting spring; a second connecting block 107 is fixedly connected to the other end of the upper semi-arc shell, and a plug rod 108 matching the plug block is fixedly connected to the lower end surface of the second connecting block. A rectangular groove 105 is provided at the center of the inner wall of the special-shaped groove, and a matching square block is provided at the corresponding position of the first arc plate.

[0025] The special-shaped groove allows the first arc plate to be inserted into it, and the connection strength between the protection module and the clamping module is improved under the action of the magnetic attraction layer and the rectangular groove. The main function of the square block is to be inserted into the rectangular groove. The function of the first connecting spring is to serve as a connecting medium between the inner wall of one side of the first connecting block and the plug block. The lower half arc shell and the upper half arc shell can be fixedly connected together through the interaction of the first connecting spring inside the first connecting block, the plug block and the plug rod at the lower end of the second connecting block. Because the protection module and the clamping module are connected by magnetic attraction, when the protection module or the clamping module is damaged, it is convenient to disassemble the two and to maintain the damaged situation.

[0026] The inner and outer surfaces of the upper and lower semi-arc shells are both provided with protective layer modules, which are composed of a conductor shielding layer 301, a lead sheath layer 302, a polyethylene sheath layer 303, and a polymer coating 304 from the inside to the outside.

[0027] The conductor shielding layer can prevent electromagnetic interference and electric field leakage in the submarine cable; the lead sheath layer can prevent damage to the inner walls of the lower semi-arc shell and the upper semi-arc shell; the polyethylene sheath layer can prevent the risk of damage to the lower semi-arc shell and the upper semi-arc shell by marine organisms; the polymer coating can improve the corrosion and wear resistance of the outer surfaces of the lower semi-arc shell and the upper semi-arc shell, and avoid damage to the protection module due to the impact of seawater.

[0028] There are two sets of clamping modules, one set is located on the inner wall of the upper semi-arc shell, and the other end is located on the corresponding inner wall of the lower semi-arc shell. The clamping module is mainly composed of a first arc plate 201, a second arc plate 203, and a second connecting spring 202 connecting the first arc plate and the second arc plate. The first arc plate is arranged on the inner wall of the upper semi-arc shell or the lower semi-arc shell by magnetic attraction. A friction layer 204 is provided on the upper end surface of the second arc plate. One end of the second connecting spring is fixedly connected to both sides of the center of the upper end surface of the first arc plate, and the other end of the second connecting spring is fixedly connected to the lower end surface of the second arc plate.

[0029] The second connecting spring and the second arc plate can clamp and fix submarine cables of different diameters; the friction layer can increase the friction between the submarine cable and prevent the submarine cable from sliding after being clamped.

[0030] 2. Working Principle

[0031] When it is necessary to protect the submarine cable, firstly, the two first arc plates are clamped and set in the special-shaped grooves on the one side surface of the lower semi-arc shell and the upper semi-arc shell, and then the connection strength between the protection module and the clamping module is improved under the action of the magnetic attraction layer and the rectangular groove and the square block fixedly connected to the rear side surface of the first arc plate, and then the submarine cable is placed in the middle of the lower semi-arc shell and the upper semi-arc shell, and then the first connecting block and the second connecting block are contacted, and the first connecting spring and the plug block inside the first connecting block cooperate with the plug rod at the lower end of the second connecting block to fix the lower semi-arc shell and the upper semi-arc shell together, and then the submarine cable is clamped and fixed under the action of the second connecting spring and the second arc plate, and then the submarine cable and the protection module can be well protected under the action of the protective layer module.
