[0002] Submarine cables are cables wrapped in insulating materials, laid on the seabed, and used for telecommunication transmission. Submarine communication cables are mainly used for communication services, which are expensive but highly confidential. Submarine power cables are mainly used to transmit high-power electricity underwater, and have the same function as underground power cables, except that they are used in different occasions and laid in different ways. Cables in shallow sea areas are laid underground, and fishing boats in shallow sea areas may damage the cables when they drop anchors when docking. Therefore, when a cable fails, a sensor device that detects cable failure is needed to detect the cable.

Secondly, since there are many fish schools on the seabed, the intelligent diving equipment may be collided with the fish schools when carrying sensors, thereby causing damage to the sensor equipment. Therefore, a sensor for detecting submarine cable faults is proposed to solve the above problems. Utility Model Content

[0023] A hanger 2 is provided on the top of the outer shell 1, and the hanger 2 consists of a metal frame at the bottom and a metal ring at the top. A bottom pad 5 is installed at the bottom of the outer shell 1, and rib plates 6 are provided between the four outer sides of the inner shell 9 and the four inner sides of the outer shell 1. An arched mounting frame 8 is installed on the top of the inner shell 9, and electromagnetic pulse structures 3 for driving away fish are provided on both sides of the outer shell 1.

[0024] It should be noted that the sensor equipment for detecting submarine cables needs to use a crane to hook the hanging piece 2 and sink it into the sea for operation.

[0025] Specifically, when it is necessary to use a sensor for detecting submarine cables to detect the location of cable faults, the hanger 2 can be hooked by a crane and then sunk into the sea. At the same time, the electromagnetic pulse structure 3 can be used to drive away the fish in the sea. When the sensor equipment sinks to the specified position in the sea, the sensor lifting structure 7 can be used to move the acoustic wave sensor in the space 4 inside the inner shell 9 out to detect the fault location of the submarine cable.

[0026] In an optional embodiment, the sensor lifting structure 7 includes an acoustic wave sensor body 701, an electric push rod 702, a quadrilateral slide 704 and a lifting plate 705.

The acoustic wave sensor body 701 is installed at the bottom of the lifting plate 705.

[0027] It should be noted that the acoustic wave sensor body 701 is a public technology known in the prior art and has the function of detecting submarine cable faults. The working principle and model specifications thereof will not be further elaborated in this article.

[0028] Specifically, when it is necessary to start the sensor lifting structure 7 to move the acoustic wave sensor body 701 out of the accommodating cavity 4, the electric push rod 702 can drive the lifting plate 705 to move the acoustic wave sensor body 701 out of the cavity 4 under the action of the slide groove 703 and the quadrilateral slide 704, and then the acoustic wave sensor body 701 can be started to detect the fault position of the submarine cable.

[0029] In an optional embodiment, the electromagnetic pulse structure 3 includes a voltage controller 301 and a pulse generator 302.
