Embodiment 1

[0031] see figure 2 As shown, the embodiment of the present invention provides a kind of subsea photoelectric separation equipment, comprising:

[0032] Anti-pressure cylinder 1, the first end of the anti-pressure cylinder 1 is an open end, and the second end away from the first end is a closed end. The anti-pressure cylinder 1 is a hollow structure similar to a cup, and its shape is preferably a cylinder structure, the anti-pressure cylinder 1 adopts an open end and a closed end structure, which can significantly reduce the sealing leakage point. Compared with the open structure at both ends in the prior art, the sealing performance is higher and the sealing reliability is higher.

[0033] End cap 9, the end cap 9 is located in the pressure-resistant cylinder 1, and the end cap 9 and the pressure-resistant cylinder 1 jointly form a sealed cavity structure, and a through hole for penetrating the photoelectric composite cable 7 is opened on the end cap 9. After the tail end ...

Embodiment 2

[0039] see figure 2 As shown, the embodiment of the present invention provides a seabed photoelectric separation device. The difference between this embodiment and Embodiment 1 is that an annular flange sealingly connected with the end cover 9 is provided on the inner wall of the pressure-resistant cylinder 1, and the annular flange is The edge is used to limit the end cover 9. On the end cover 9, a metal seal ring 14 is arranged between the end face in the cavity and the connecting surface of the annular flange. The metal seal ring 14 is a metal C-shaped seal ring, and an annular coil spring is sleeved in the metal C-shaped seal ring. 16. Between the outer circle of the end cover 9 and the inner wall of the pressure-resistant cylinder 1, a plurality of O-rings 15 are arranged at intervals. When the end cover 9 is connected to the annular flange, the junction between the end cover 9 and the inner wall of the pressure-resistant cylinder 1 and the annular flange is sealed and...

Embodiment 3

[0041] see figure 2 As shown, the embodiment of the present invention provides a submarine optoelectronic separation device. The difference between this embodiment and Embodiment 1 is that an end cover compression ring 6 is provided on the end cover 9 outside the cavity. The tight ring 6 is provided with a plurality of screw holes along the circumferential direction of the end cover pressing ring 6 . The outer circle of the end cover compression ring 6 is provided with an external thread, and the inner wall of the compression cylinder 1 is provided with an internal thread connected with the end cover compression ring 6, and the end cover compression ring 6 is threadedly connected with the inner wall of the compression cylinder 1 , Screws are penetrated into the threaded holes of the end cover compression ring 6 to resist the end cover 9, so as to realize the compression and sealing between the end cover 9 and the annular flange. When realizing the sealed connection between t...

Abstract

The invention discloses submarine photoelectric separation equipment, which belongs to the technical field of submarine observation equipment and submarine observation networks. The submarine photoelectric separation equipment comprises: a pressure-resistant cylinder, wherein a first end of the pressure-resistant cylinder is an open end, and a second end far away from the first end is a closed end; an end cover which is located in the compression-resistant cylinder, wherein the end cover and the compression-resistant cylinder jointly form a sealed cavity structure, and the end cover is provided with a through hole for the photoelectric composite cable to penetrate through; an injection molding body which is located in the through hole of the end cover, wherein the photoelectric composite cable is in sealed connection with the end cover through the injection molding body; and a cable watertight connector and an optical fiber watertight connector which are respectively connected to the second end in a sealing manner. According to the pressure-resistant cylinder, the first end is the open end, the second end far away from the first end is the closed end, the open end is sealed with the end cover, the end cover and the tail end of the photoelectric composite cable are sealed in an injection molding mode, the sealing performance of the photoelectric composite cable is more reliablethan that of a photoelectric composite cable adopting a sealing ring and other sealing modes, and the submarine photoelectric separation equipment is suitable for the deepwater 4KM marine environment.

Description

technical field [0001] The invention relates to the technical field of seabed observation equipment and seabed observation network, in particular to a seabed photoelectric separation device. Background technique [0002] The submarine observation network can be applied to the development of submarine resources, submarine environment monitoring, marine scientific research, marine military network construction and other fields. Since ordinary submarine cables alone cannot achieve long-distance and large-capacity information transmission, submarine communication with photoelectric composite cables must be used. system. [0003] The submarine observation network is an ocean observation network formed by connecting shore-based equipment, photoelectric composite cables, and submarine main base stations. The main subsea base station is an important device to realize power conversion, data aggregation, transmission and control. The backbone cable of the submarine observation netwo...
