Abstract

The invention relates to a cable lap joint device. The device belongs to the field of cable connection. The device comprises a first lap joint shell and a second lap joint shell. A first inserting piece and a second inserting piece are connected into the first lap joint shell and the second lap joint shell. The first inserting piece is connected with the second inserting piece; the first insertingpiece is connected and fixed through a mounting flange and the first adjusting flange; the second inserting piece is connected and fixed through a second adjusting flange and a mounting base; the tail parts of the first inserting piece and the second inserting piece are connected with a tail fiber; the first inserting piece, the connecting piece connected to the first inserting piece, the secondinserting piece and the connecting piece connected to the second inserting piece are all arranged in a cavity formed by connecting the first lap joint shell and the second lap joint shell. The tail parts of the first lap joint shell and the second lap joint shell are connected with a locking mechanism, so that the problem that underwater cables are difficult to connect is solved, and the beneficial effects are as follows: the application in a complex water environment is met; the internal structure of the cable lap joint device is novel in design, multi-watertight protection and redundant safety design can be achieved, the construction reliability is improved, and the locking mechanism ensures the sealing performance of the underwater environment.

Description

technical field [0001] The invention belongs to the field of underwater cable connection, in particular to a cable overlapping device. Background technique [0002] The invention relates to marine construction, shallow sea and deep sea subsea tunnel construction engineering field. [0003] Underwater cables are one of the important components in the construction of subsea tunnels by immersed tube method. It is the channel for controlling the ballast pump, drive motor, camera, lighting, measurement and control equipment, etc. inside the immersed tube. It provides power and communication functions for various equipment and instruments inside the immersed tube. When the cable encounters the cutting cable scene at the construction site, it is necessary to lap the cut cables. The safety and reliability after lapping are also one of the key technologies in the installation process of the immersed tube. [0004] An existing cable lapping technology generally adopts connector tech...
