The invention relates to the field of ship ballast tank pipe suction port accessory structure drain holes, in particular to a method for arranging structure drain holes near a pipe suction port in a ballast tank, which comprises the following steps: S1, determining the arrangement position of the suction port in the ballast tank and the area of the suction port; s2, by taking the suction port as the center, forming multiple stages of drain holes around the suction port; according to the method, the drainage holes are gradually increased from the far suction port end to the near suction port end, so that water flow can effectively and smoothly flow to the suction port position from the far suction port end theoretically through the matching arrangement of the drainage holes, and the problems that the water flow speed of a ballast tank is too low, and the suction port area is too large are effectively solved. And the suction port water pump idles.

    本发明涉及船舶压载舱管子吸口附件结构流水孔领域,具体为一种压载舱内管子吸口附近结构流水孔布置方法,包括以下步骤:S1、确定压载舱内吸口的布置位置以及确定吸口的面积;S2、以吸口为中心,围绕吸口位置,设置多级流水孔;S3、依据吸口面积按比例计算出各级流水孔面积,本发明通过由远吸口端向近吸口端呈现逐步递增的形式设置,这样的流水孔配比布置理论上可以有效的使水流由远吸口端顺畅的流向吸口位置,从而有效的解决压载舱水流速度过慢,吸口水泵空转的问题。
