Embodiment Construction

[0025] Further illustrate the present invention below in conjunction with accompanying drawing.

[0026] Referring to the accompanying drawings, the photoelectric conversion device of this embodiment includes a pressure-resistant housing, which includes a cylinder 2 and a left end cover 1 and a right end cover 5 that are sealed and installed on the openings at both ends of the cylinder in the axial direction. The left end cover 1 and the right end cover 5 abut against the corresponding axial end face of the cylindrical body 2 and are fixed by bolts, and the bolts penetrate the corresponding end caps and extend from the axial end face of the cylindrical body into the side wall of the cylindrical body.

[0027] In order to further improve the tightness of the inner cavity of the cylinder, the left end cover 1 and the right end cover 5 have bosses extending into the cylinder body 2, and the periphery of the bosses is in close contact with the inner wall of the cylinder body 2, and...

Abstract

The invention discloses a photoelectric conversion device based on seabed signal transmission, and the device comprises a crush-resisting housing. The crush-resisting housing is provided with an optical fiber splice and a circuit connector in a sealed and embedded manner. The circuit connector comprises an electric signal pin and a power pin. The interior of the crush-resisting housing is provided with a photoelectric conversion module which is connected between the optical fiber splice and the electric signal pin, and is also provided with a voltage conversion module which is used for supplying power to the photoelectric conversion module. The input end of the photoelectric conversion module is connected with the power pin. The device achieves the photoelectric conversion of a seabed signal through a relay. Compared with each conventional device employing an expensive photoelectric hybrid wet-plug connector to connect a seabed observation network, the device greatly saves the cost of the connector, and can achieve the same function through employing a low-cost electric we-plug connector to connect the relay.

Description

technical field [0001] The invention belongs to the field of seabed observation, in particular to an underwater networking cable repeater based on photoelectric conversion of seabed signal transmission. Background technique [0002] Traditional ocean observation methods include scientific research ships, underwater robots, and offline observation equipment, but these are difficult to meet the growing needs of marine scientific research and development. For this reason, in the past ten years, Europe, America, Japan and other countries and regions have successively researched and developed the tethered submarine observation network. The seabed observation network can provide a long-term, continuous, real-time and in-situ observation marine scientific research means because of its strong continuous power supply capability and high-bandwidth communication capability. [0003] In my country, which has a vast ocean area, the tethered submarine observation network technology is ve...
