The invention provides a gravity type drainage water retaining structure and a ballast tank water discharge device, and relates to the technical field of ship ballast tank water discharge, the gravity type drainage water retaining structure comprises a water retaining plate, a water guide inclined plate and a hinge assembly; after a ship reaches a wharf, when the water ballast tanks need to be discharged, the water ballast tanks are opened, liquid in the water ballast tanks flows to the water guide inclined plates under the action of gravity, after the liquid is blocked by the water guide inclined plates, the flowing direction of the liquid is changed, the liquid is discharged towards the outboard, the water baffles have the resistance effect on the liquid, discharged water columns do not generate too large impact force, and the water ballast tanks can be discharged out of the wharf. The method has the advantages that no harm is caused to equipment and personnel activities of a wharf, the ship is safer when the ballast water is discharged at the wharf, and the problems that in the prior art, a high-pressure water column is formed due to huge water pressure when the ballast water is discharged due to the fact that the drainage hole is small and the ballast water amount is huge are solved. And harms can be caused to equipment and personnel activities of the wharf.

    本发明提供了一种重力式泄流挡水结构及压载舱水排放装置,涉及船舶压载舱水排放技术领域,包括:挡水板、导水斜板和铰接组件;船舶靠岸码头后,当需要泄放压载水舱时,打开压载水舱,压载水舱里的液体在重力作用下流向导水斜板,经过导水斜板阻挡后,改变液体流动方向,朝向舷外排出,挡水板对液体具有阻力作用,泄流出的水柱不会产生过大的冲击力,不会对码头的设备和人员活动产生危害,让船舶在码头泄放压载水时更加安全,缓解了现有技术中存在的由于泄流孔较小同时压载水量巨大,在排放压载水时由于巨大的水压会形成一道高压水柱,会对码头的设备和人员活动产生危害的技术问题。
