Description

Technical Field

[0001] The invention belongs to the technical field of submarine cable fault detection and relates to a novel submarine cable fault detection system. Background Art

[0002] With the further expansion of island development, submarine cables are playing a vital role in cross-sea power and communications. However, fishing vessels and ships dragging anchors, coupled with deteriorating seabed conditions, are causing frequent damage to submarine cables, anchor damage, and other faults. Traditional submarine cable fault detection devices primarily utilize methods such as DC superposition and DC component methods, which suffer from low detection accuracy and large measurement errors. When a cable fault occurs, the precise location of the fault cannot be accurately located, complicating fault detection and repair efforts and increasing submarine cable maintenance costs. Therefore, a more efficient system is needed to accurately detect and precisely locate cable faults. Summary of the Invention

[0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide a new submarine cable fault detection system that can accurately detect and precisely locate cable faults.

[0004] To achieve the above-mentioned objectives, the novel submarine cable fault detection system described in the present invention includes a fuselage, which includes a main body section, a flexible transition section and a tail section, wherein the main body section and the tail section are connected via a flexible transition section, an information central processing unit and a GPS positioning device are provided in the main body section, and an ultrasonic detection device is provided on the outside of the main body section, wherein the information central processing unit is connected to the GPS positioning device and the ultrasonic detection device.

[0005] The ultrasonic detection device includes an ultrasonic transmitter and an ultrasonic receiver, wherein the ultrasonic transmitter transmits ultrasonic waves to the cable, and the ultrasonic receiver receives the returned ultrasonic signal, converts the returned ultrasonic signal into an electrical signal, and then sends it to the information central processing unit.

[0006] An alarm system is provided in the main body section, wherein the alarm system is connected to the information central processing unit.

[0007] A control unit is provided in the main section, a drive motor is provided in the transition section, and propeller blades are provided on the outside of the transition section, wherein the output shaft of the drive motor is connected to the propeller blades, the control unit is connected to the drive motor, and the control unit is connected to the information central control unit.

[0008] A transverse pull rod is provided in the transition section, a torque controller and a direction change processing module are provided in the main section, the output end of the direction change processing module is connected to the control end of the torque controller, and the torque controller is connected to the transverse pull rod through a transmission shaft.

[0009] The direction-changing processing module includes an electromagnetic wave transmitting device and a signal processor. The electromagnetic wave transmitting device transmits electromagnetic waves to the cable. After being transmitted through the cable, the electromagnetic waves are received by the electric diaphragm on the signal processor. The output end of the signal processor is connected to the input end of the torque controller.

[0010] When the signal processor is located on one side of the cable, the intensities of the electromagnetic waves at both ends of the electric diaphragm are different, thereby forming a potential difference between the two ends of the electric diaphragm.

[0011] The torque controller controls the torque controller according to the direction of the potential difference. The torque controller drives the transverse pull rod through the transmission shaft, so that the transverse pull rod moves toward the side with a larger potential difference, thereby causing the fuselage to move toward the direction of the cable.

[0012] The shell of the GPS positioning device is made of waterproof and corrosion-resistant materials.

[0013] The casing of the alarm system is made of waterproof and corrosion-resistant materials.

[0014] The present invention has the following beneficial effects:

[0015] The novel submarine cable fault detection system described in the present invention adopts ultrasonic detection to accurately detect submarine cable faults during specific operation. The fuselage moves along the submarine cable, continuously outputs ultrasonic waves to the cable through the ultrasonic detection device, receives the reflected ultrasonic signal, converts it into an electrical signal, and then sends it to the information central processing unit. The information central processing unit calculates the time difference between the emission of the ultrasonic signal and the reception of the electrical signal. When the time difference suddenly changes, it indicates that the cable below has a fault. At the same time, the GPS positioning device is used for positioning, thereby accurately detecting and precisely locating the cable fault, solving the problem that the traditional submarine cable detection system can only locate the approximate range but not the fault point, and accurately locating the cable fault, saving the cost of fault search and improving maintenance efficiency.
