Abstract

The invention relates to a photoelectric composite submarine cable pressure-resistant waterproof joint, which comprises a spring, a joint body, a taper sleeve, a first fixing piece, an adapter, a power supply connecting piece and a clamping sleeve piece, wherein the spring is fixedly arranged on the outer side of the joint body and connected with the joint body, the spring is used for sleeving a photoelectric composite submarine cable, the taper sleeve located in the joint body is used for fixing the photoelectric composite submarine cable, the rear end of the joint body is fixedly connected with the front end of the adapter through the first fixing piece, a cavity is formed in the portion between the joint body and the adapter and filled with waterproof silicone grease, the power supply connecting piece electrically connected with the cable is arranged in the adapter, the clamping sleeve piece is used for fixing an optical fiber penetrating out of the cavity, and is fixed in the adapter, and the adapter is connected with an external sensor short section. According to the invention, the functions of pressure resistance, sealing and corrosion resistance required when the photoelectric composite submarine cable is used are met, accidental breaking at the joint of the submarine cable can be avoided, good sealing performance is achieved, and the waterproof design of deep sea operation is met.

Description

technical field [0001] The invention relates to the technical field of joints, in particular to a pressure-resistant waterproof joint of a photoelectric composite submarine cable. Background technique [0002] 4-Component Ocean Bottom Cable (4C-OBC) is a device that can collect full-wave seismic signals (including longitudinal waves and shear waves) on the seabed. In the process of making 4-component submarine optical cables, it is necessary to combine sensor subsections and photoelectric The composite cable is connected so that the optical fiber in the photoelectric composite cable, the cable is connected with the sensor located on the sensor pup. Photoelectric composite submarine cables are usually used in deep seawater, for example, the working water depth reaches 1000m (meters), and the withstand pressure is not less than 10MPa. At the same time, since the sensor sub-section is powered by the cable, and the data collected by the sensor on the sensor sub-section is trans...
