Description

TECHNICAL FIELD

[0002] As an important tool for human to explore the mystery of deep sea, unmanned ocean detector plays an irreplaceable role in the field of ocean resource exploration, environmental monitoring, geological research and biodiversity survey, and the pressure-tight sealing performance is the core technology to ensure the stable operation of internal electronic equipment, energy system and data module of the detector, which is directly related to the success or failure of the detection task and the safe recovery of the equipment. If the sealing fails, seawater penetration will cause circuit short circuit, equipment corrosion, and even cause the whole detector to fail. Therefore, how to achieve reliable sealing design under high pressure environment has always been the research focus in this field.

[0003] At the same time, in order to realize the picture collection and scene observation of deep sea environment, a high-power illuminating lamp is usually arranged at the head of the detector to penetrate the optical attenuation of seawater and illuminate the detection area. At present, the illuminating lamp in the prior art is designed as an external type independent of the cabin, that is, the lamp body is fixed to the outside of the cabin by a support, which is physically isolated from the internal cabin. This design requires an independent power supply battery for the illuminating lamp, and the capacity of the independent battery is usually small due to the limitation of the overall volume and load capacity of the detector, which is difficult to meet the demand of long-time and high-brightness illumination. If the power supply system inside the cabin is shared with the illuminating lamp, the power inside the cabin needs to be introduced to the external lamp through a cable, and there are technical difficulties in the sealing treatment of the cable penetration. Even if the traditional O-ring or packing seal structure is used, the sealing interface between the cable and the penetration hole is still prone to gaps under the impact of high-pressure seawater, which causes seawater to penetrate into the cabin along the cable, resulting in a decrease in the sealing performance of the cabin, and even causing safety hazards such as electric leakage and short circuit.
