Floating platform and submarine cable connecting structure

The invention relates to a floating platform and submarine cable connecting structure. The floating platform and submarine cable connecting structure is characterized in that a vertical pipe is arranged in a floating platform, one end of the vertical pipe is communicated with the bottom of the floating platform, and connecting assemblies which can be mutually assembled, disassembled and fixedly connected are arranged between the other end of the vertical pipe and a submarine cable. A submarine cable is led to the position inside the floating platform and above the waterline through the connecting structure, maintenance personnel assemble, disassemble and replace the submarine cable inside the floating platform, the maintenance personnel do not need to dive to the position below the floating platform, maintenance difficulty is greatly reduced, and construction convenience, safety and working efficiency are effectively improved. When the floating platform is laid, laying of the floatingplatform can be completed
