The invention discloses an internal trade ship bottom ballast injection system which is characterized in that a vertical ballast pipe is additionally arranged at a ballast header pipe and a ballast branch pipe, and the vertical ballast pipe is communicated with the ballast header pipe and the ballast branch pipe; openings in the lower ends of the vertical ballast pipes are aligned with the outer surface of the hull shell plate so as to introduce external water, and openings in the upper ends of the vertical ballast pipes are communicated with the hull internal space above the hull internal bottom plate; a grating cover is arranged at the lower end of the vertical ballast pipe so as to filter large-particle impurities in the ballast water; a remote control valve I is arranged above the grating cover and is used for controlling the communication state of the vertical ballast pipe and an external water area; a detachable filter screen is arranged above the remote control valve I and can filter small particle impurities in the ballast water; a watertight cock is arranged at the upper end of the vertical ballast pipe. Non-auxiliary power injection of the bottom ballast tanks of the ship is achieved through gravitational potential energy generated by the height difference between the outside water level of the ship and the bottom ballast tanks, a ballast pump does not need to be started, and therefore energy consumption is saved, the energy efficiency level of the ship is improved, and injection can be conducted on the multiple bottom ballast tanks at the same time.
本发明公开了一种内贸船舶底压载注入系统,在压载总管和压载支管位置处增加一个垂直压载管,垂直压载管与压载总管和压载支管连通;垂直压载管下端的开口与船体外壳板外表面相对齐以通入外界水体,垂直压载管上端的开口联通船体内底板之上的船体内部空间;在垂直压载管下端设格栅盖,以过滤压载水中较大颗粒杂质;格栅盖上方设遥控阀一,控制垂直压载管与外界水域的联通状态;遥控阀一上方设可拆卸的滤网,可过滤压载水中较小颗粒杂质;垂直压载管上端设水密旋塞。利用船舶外界水位与底压载舱间高差产生的重力势能实现船舶底部压载舱的无辅助动力注入,不需要启动压载泵,从而节约能耗,提升船舶能效水平,且可同时注入多个底压载舱。
