The invention discloses a variable-diameter duct for an anti-pirate ejector, the variable-diameter duct comprises a seat ring fixed on a shunt ring and a plurality of guide plates arranged on the seat ring, helical tooth rings are arranged on the two sides of the part, sleeved on the seat ring, of each guide plate, and each helical tooth ring is meshed with the helical tooth ring on the adjacent side. The variable-diameter duct is arranged on the inner side of the double-cavity water bag and is folded or unfolded along with the change of the volume of the double-cavity water bag cavity to adjust the diameter of the flow channel of the bow nozzle and change the flow of the nozzle, so that the flow difference exists between the bow nozzle and the stern nozzle of the ejector; the anti-pirate near-board connection device moves in the bow and stern directions of the ship by utilizing the flow difference of the bow and stern nozzles of the ejector so as to attack pirates at proper positions.
本发明公开了一种用于防海盗喷射器的变径涵道,所述变径涵道包括固定在分流环上的座圈、设置在座圈上的若干个导流板,每个导流板的套在座圈上的部位两侧均设有斜齿环,每个斜齿环均与其邻侧的斜齿环相啮合。本发明将变径涵道设置在双腔水囊的内侧,随着双腔水囊囊腔体积的变化合拢或展开以调节向艏喷口的流道直径、改变喷口流量,从而使喷射器艏艉喷口存在流量差,通过利用喷射器艏艉喷口的流量差来使防海盗近舷接驳装置在船舶艏艉方向进行移动,以在合适位置对海盗进行攻击。
