DAMPING STRUCTURE OF STRAIGHT CYLINDER TYPE FLOATING PLATFORM

摘要

A damping structure of a straight cylinder type floating platform, being an annular structure surrounding the outer periphery of the bottom of a cylinder body (12) of the platform, and there being/being not an annular radial gap (14) between the two. The damping structure (13) is connected to a horizontal top plate (131), a horizontal bottom plate (133), an outer annular vertical plate (132), and an inner annular vertical plate (134) to form a box body, and the box body is divided into a plurality of watertight chambers; the horizontal top plate and/or the horizontal bottom plate corresponding to each watertight chamber are provided with damping holes capable of being opened or closed; by opening or closing of the damping holes in the horizontal top plate and the horizontal bottom plate, the chambers are filled with water introduced with sea, or a closed floating chamber is formed, or a closed air floating chamber is formed, so as to meet requirements under different working conditions; at least one of the horizontal top plate and the horizontal bottom plate extends and protrudes out of a junction to form a top outer front edge (135) and/or a bottom outer front edge (136), respectively; the top outer front edge and/or the bottom outer front edge are provided with/are not provided with the damping holes. By means of the damping structure, the quality of additional water is improved, and viscous damping of the motion of the platform is increased, so that the motion performance of the platform is improved.
