The invention relates to a rapid emptying ballast tank, and belongs to the technical field of ship ballast tank design. The rapid emptying ballast tank comprises a water ballast tank, wherein a flow guide groove is formed in the bottom of the water ballast tank and located outside the water ballast tank, and the direction of the flow guide groove is perpendicular to the direction of an upwards-protruding aggregate at the bottom of the water ballast tank; flow guide holes are formed in positions between a plurality of adjacent aggregates so as to enable the ballast water tank to be communicatedwith the flow guide groove; at least one ballast water tank water flow outlet is formed in the bottom of the flow guide groove. When drainage operation is carried out, ballast water is not directly discharged from the ballast water tank any more, but flows into the flow guide groove through the flow guide holes and then is discharged. The diameter of the flow guide hole is far larger than that ofan originally-designed water flowing hole, blocking is not likely to happen, and the drainage flow speed is greatly increased; the flow guide groove aggregate does not occupy the space in the flow guide groove, the problem that the aggregate in the cabin occupies the volume of flowing water is solved, the circulation area is increased, the drainage flow speed is increased, and thus the drainage efficiency is improved.

    本发明涉及一种快速排空压载舱,属于船舶压载舱设计技术领域。一种快速排空压载舱,包括压载水舱,在压载水舱的底部,位于压载水舱外部设置一导流槽,导流槽的方向垂直于压载水舱底部向上凸起的骨材的方向;选取若干相邻骨材之间的位置设置导流孔,使压载水舱与导流槽保持连通;导流槽底部设有至少一个压载水舱水流出口。进行排水作业时,压载水不再由压载水舱直接排出,而是经由导流孔流入导流槽后排出。导流孔的直径远大于原有设计的流水孔直径,不易堵塞,极大地增加了排水流速;导流槽骨材不占用导流槽内的空间,解决了舱内骨材占用流水体积的问题,增大了流通区域,提高了排水流速,从而增加了排水效率。
