The invention discloses an active marine storage tank liquid tank swash device which comprises a liquid tank, a longitudinal swash plate and a plurality of transverse swash plates are arranged on the side wall of the liquid tank, the longitudinal swash plate is installed on the side wall of the liquid tank in the longitudinal direction of the liquid tank, and the transverse swash plates are installed between the upper side wall and the lower side wall of the liquid tank at intervals in the horizontal direction. The upper and lower ends of each transverse swash plate are respectively in sliding connection with the upper and lower side walls of the liquid tank; a plurality of flow guide holes are formed in the longitudinal swash plates and the transverse swash plates; the upper end and the lower end of the transverse swash plate are connected with sliding blocks, guide rails are installed on the upper wall face and the lower wall face of the liquid tank, and the sliding blocks are slidably connected with the guide rails. Liquid oscillation in the liquid tank can be restrained to a certain degree, back-and-forth movement is conducted according to the oscillation frequency of the liquid, dissipation of oscillation energy in the liquid is accelerated, the time for the liquid level to recover to be calm is shortened, the amplitude of oscillation pressure in the liquid oscillation process can be obviously reduced, and the attenuation speed of the oscillation pressure is increased till the liquid level recovers to be calm.
本发明公开了一种主动式船用储罐液舱的制荡装置,包括液舱,所述液舱侧壁设有纵向制荡板和多块横向制荡板,其中,纵向制荡板沿液舱纵向方向安装在液舱侧壁,多块横向制荡板沿水平方向间隔安装在液舱上下侧壁之间,每块横向制荡板的上下两端分别与液舱上下侧壁滑动连接;所述纵向制荡板和横向制荡板上均设有若干导流孔;所述横向制荡板的上下两端均连接有滑块,液舱上下壁面均安装有导轨,所述滑块与导轨滑动连接。本发明可在一定程度上抑制液舱内的液体晃荡,根据液体晃荡的频率往返运动,加速液体内部晃荡能量的耗散,缩短液面恢复平静的时间,能明显降低液体晃动过程中的晃动压力的幅值,加快晃动压力的衰减速度,直至液面恢复平静。
