The invention discloses an ejector and a method for adjusting the position of an anti-pirate near-board connection device, the device comprises an outboard ejection opening installed on an injection pump of the anti-pirate near-board connection device, and the ejector is provided with a stern-facing nozzle with a fixed caliber and a bow-facing nozzle with an adjustable caliber. A flow adjusting valve assembly is arranged towards the bow nozzle, the flow adjusting valve assembly adjusts the diameter of a flow channel through expansion or contraction of different water bags in the flow adjusting valve assembly so as to change the flow of the nozzle, and therefore the position of the pirate prevention near-board connection device in the bow and stern direction is changed under the action of the bow and stern jet flow difference. According to the invention, the diameter of the bow nozzle of the ejector can be automatically adjusted according to the working gear of the ejector pump, and the flow difference of the bow nozzle and the stern nozzle of the ejector is utilized to enable the anti-pirate near-board connection device to move in the bow direction and the stern direction of a ship so as to attack pirates at proper positions.

    本发明公开了一种用于调节防海盗近舷接驳装置位置的喷射器及方法,所述装置包括安装在所述防海盗近舷接驳装置的喷射泵的舷外喷射口上,喷射器上设有口径固定的向艉喷口和口径可调的向艏喷口,向艏喷口设置有一个流量调节阀总成,流量调节阀总成通过其内部不同水囊的膨胀或收缩来调节流道直径以改变喷口流量,从而在艏艉喷射流量差的作用下改变所述防海盗近舷接驳装置在艏艉方向的位置。本发明根据喷射泵的工作档位可自动调节喷射器的向艏喷口的直径,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。
