Abstract

The invention discloses a double swash device for a ship liquid tank. The device comprises a horizontal swash panel, n vertical swash panels, a horizontal swash panel connecting device and a verticalswash panel connecting device; the horizontal swash panel connecting device comprises a fixed pulley, a traction steel wire rope, a fixed arm and a first motor, one end of the fixed arm is connected with the ship liquid tank, the other end of the fixed arm is connected with the fixed pulley, one end of the traction steel wire rope penetrates through the fixed pulley and is connected with the horizontal swash panel, and the other end of the traction steel wire rope is connected with the first motor; multiple through holes are formed in the horizontal swash panel and all the vertical swash panels. The device has the following advantages that occurrence of strong nonlinear phenomena such as top-hitting and rolling can be accelerated under the condition of a low liquid carrying rate, the top-hitting liquid falling time is shortened, the energy of liquid in the tank is consumed, and damage of impact load generated by sway to the tank wall is lowered.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a double sloshing device and a swaying method for a ship liquid tank capable of reducing damage to bulkheads caused by impact loads generated by sloshing. Background technique [0002] During the voyage of the oil tanker at sea, it will carry a large amount of cargo oil. Under severe sea conditions, the hull will sway and heave under the action of external forces such as wind, waves, currents, etc., and the tank will not be full of cargo. The oil also moves with the movement of the hull, and the cargo oil in the tank sloshes with the movement of the hull. The impact load generated by the sloshing will cause certain damage to the bulkhead. When the impact load is greater than the limit that the bulkhead can bear , the bulkhead will be damaged, which will have a great impact on the stability of the oil tanker, and even endanger the lives of the entire crew in severe cases. ...
