[0029] The present invention provides a water surface real-time fluorescence detection device for troubleshooting submarine cable oil leakage, comprising a buoy 1, a towing line 6, a water inlet pipe and a fluorescence sensor, wherein the towing line 6 is arranged on the buoy 1, the water inlet pipe has a water inlet end 2 and a water outlet end 3, the water inlet end 2 is arranged on the upper surface of the buoy 1, and the water outlet end 3 is arranged on the lower surface of the buoy 1, the fluorescence sensor has a sensor probe 5, the sensor probe 5 is installed at the water outlet end 3, and the sensor probe 5 signal is connected to a receiver; wherein a power device drags the buoy on the water surface through the towing line, the water inlet pipe is used to collect insulating medium on the water surface and convert it into insulating medium underwater, and the sensor probe 5 is used to detect the insulating medium underwater.

[0030] Specifically, when checking whether there is an oil leakage fault in the submarine cable, the device can be first placed in the area to be detected on the sea surface, and the floating body 1 floating on the sea surface can be dragged by a power device, wherein the power device includes but is not limited to various speedboats, motorboats, seaplanes and other vehicles that can operate on the sea surface. A water inlet pipe is installed on the floating body 1, and the water inlet end 2 and the water outlet end 3 of the water inlet pipe are respectively located on the upper and lower surfaces of the floating body 1. When the insulating medium on the sea level flows in from the water inlet end 2 and flows to the water outlet end 3 below the sea level, the insulating medium on the sea level is converted into the insulating medium below the sea level, and then the sensor probe 5 of the fluorescent sensor installed at the water outlet end 3 performs real-time fluorescence detection on the insulating medium. The sensor probe 5 transmits the detected signal information to the corresponding receiver by wire or wireless means. Based on the existing ultraviolet fluorescence analysis method, this method can be used to extract weak fluorescence test signals from the insulating medium, thereby judging the oil pollution components of the insulating medium, and then judging whether there is an oil leakage fault point in the submarine cable in the area. The specific implementation method is: the floating body 1 is quickly towed on the sea surface by a ship, so that the water substances in the area are quickly converted into underwater substances through the water inlet pipe, and the sensor probe 5 performs real-time fluorescence detection on the substances in the high-speed flowing water body, thereby accelerating the detection speed, and then quickly determining whether there is an oil leakage fault point in the submarine cable in the area, thereby improving the detection efficiency.

Further, the pipe body 4 of the water inlet pipe passes through the upper and lower surfaces of the floating body 1, and the pipe body 4 is Z-shaped.

[0036] Specifically, the center line of the port of the water inlet end 2 is parallel to the horizontal plane, and it is funnel-shaped from large to small from the outside to the inside, which can better collect substances on the water surface. The pipe body 4 is Z-shaped and the middle part passes through the floating body 1, which can ensure the stability of the water inlet pipe, so that the device can be safely used under the towing of the ship, ensuring that the detection can be completed smoothly.
