Bionic damping stabilizer

Abstract

The invention relates to a fishing boat, a fishing touring, a platform, a wharf boat, a heavy lift vessel, a small naval vessel and the like, and is applied to a bionic damping stabilizer (called as aFlopper) in offshore sailing or offshore operation. The bionic damping stabilizer comprises an adjustment balance block, a bionic damping wing and a flow guide wing structure, and a mounting modularsupport structure, wherein the modular support structure comprises a modularized base, a support rod frame, a pulley device and the like; and the formula of the Flopper damping moment is researched and derived, and the stabilization effect is analyzed and studied. The actual offshore experiment result shows that the stabilization effect of the ship with the bionic stabilizer can reach 59% or abovewhen the ship is stationary at sea, the average stabilization effect during navigation can reach 45% or above, and the engineering feasibility and the satisfactory stabilization effect of the deviceare verified.

Description

technical field [0001] The invention relates to fishing boats, fishing boats, platforms, pontoons, heavy cranes, small ships and other ship types, and a bionic damping and anti-rolling device (called a Flopper) that can generate damping torque when encountering random waves while sailing at sea, in particular to a bionic Damping anti-roll device. Background technique [0002] When a ship sails in waves, due to the influence of wind, waves, currents and other factors, it will produce six degrees of freedom motion: roll, pitch, yaw, sway, surge, and heave. Improper control of these movements will cause attitude instability and endanger the safety of ship navigation. There are three main methods to keep the ship's attitude stable: (1) Resonant rolling stability—reduce the inherent rolling frequency of the ship and avoid the wave disturbance resonance frequency. Considering this aspect in the design of the ship, the occurrence rate of resonance rolling can be reduced; (2) Dampi...

Problems solved by technology

[0003] Correspondingly, there are also some passive anti-rolling devices on the market, such as the controllable passive anti-rolling water tank corresponding to the utility patent No. 201721826467.7, but in the actual use process, the anti-rolling water tank is noisy and complicated to use. However, according to the survey, it is used less frequently; another example is the anti-rolling device and ship corresponding to the invention patent No. 201580072347.X, which uses an active anti-rolling device, which needs to provide power during operation, which increases additional costs and burdens
