AI Technical Summary

Technical Problem

The existing tank swaying device is difficult to effectively suppress when facing severe liquid swaying, especially in some carrier fluids and complex sea conditions, which can easily lead to tank structure damage and ship instability.

Method used

A double shaking method including an automatic rebound shaking plate device and a combined shaking plate device is adopted. The automatic rebound shaking plate device passively applies a reaction force to the liquid through the deformation of the spring, consuming the kinetic energy of the liquid swaying; the combined shaking plate device increases the resistance of the liquid and generates bubble-carrying vortexes, further consuming the kinetic energy and potential energy of the liquid through the pore structure of the horizontal open-porous medium plate and the semi-circular arc-shaped open-porous medium plate.

Benefits of technology

Effectively suppress the sway of the tank, slow down the impact load of the liquid on the bulkhead, reduce the kinetic energy and potential energy of the sway, and improve the safety of the tank and the stability of the ship.

Abstract

The invention discloses a device for slowing down sloshing of a liquid tank. The device comprises the liquid tank, a linear guide rail sliding mechanism, a combined swash plate device and an automatic springback swash plate device. According to the device for slowing down the sloshing of the liquid tank, a double-sloshing-reduction method is adopted, firstly, the amplitude of the sloshing wave height of the free liquid surface and the kinetic energy of liquid sloshing are weakened in the middle of the liquid tank by means of the automatic rebound swash plate device; liquid sloshing energy is dissipated by means of holes of the combined swash plate device for liquid to enter and exit from the bulkhead, direct action of free surface movement of the liquid on the side wall of the liquid tank is hindered, impact load of liquid sloshing on the bulkhead is reduced, and the phenomena of top rushing and jet flow caused by climbing along the bulkhead are inhibited. Meanwhile, the position of the combined oscillation suppression plate device can be adjusted by means of the linear guide rail sliding mechanism, the energy of liquid oscillation can be dissipated to the maximum extent, meanwhile, the inherent frequency of the liquid tank is changed, resonance can be effectively avoided, and therefore the wave absorption and stabilization effects of the oscillation suppression device can be better exerted.
