The marine anti-pirate device comprises an injection pump, an injector and a pulley bracket assembly used for bearing the injection pump and the injector, the injector is installed on an outboard injection opening of the injection pump, the injector is provided with a stern-facing nozzle with a fixed caliber and a bow-facing nozzle with an adjustable caliber, and the stern-facing nozzle and the bow-facing nozzle are arranged on the injection pump. A flow regulating valve assembly is arranged towards a bow nozzle, and the flow regulating valve assembly regulates the diameter of a flow channel through expansion or contraction of different water bags in the flow regulating valve assembly so as to change the flow of the nozzle, so that the position of the marine anti-pirate device in the bow and stern directions 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 device for the ship to move in the bow and stern directions of the ship so as to attack pirates at proper positions.

    本发明公开了一种艏艉位置自调节的船用防海盗装置,包括喷射泵、喷射器、以及用以承载喷射泵和喷射器的滑轮托架组件,所述喷射器安装在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船用防海盗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船用防海盗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。
