Damping buffer device for connection between large floating bodies

The invention relates to a damping buffer device for connection between large floating bodies, which comprises a shell, an even number of liquid dampers are arranged on both sides of the shell, the liquid dampers on the same side are symmetrically arranged in pairs relative to the shell, piston shafts connected with the floating bodies are arranged on the liquid dampers, and each liquid damper comprises a cylinder. A piston plate slidably connected with the inner wall of the cylinder is arranged in the cylinder, the lower side area of the piston plate is communicated with the interior of the shell, the space is filled with buffering damping liquid, the upper side face of the piston plate is fixedly connected with the piston shaft, the upper end of the cylinder is of a closed structure, and a branch buffering cavity is formed between the upper end of the cylinder and the piston plate; according to the flexible liquid buffering device, the structure is simple, the manufacturing cost is low, flexible liquid buff
