The invention discloses a spraying device with a suction port capable of automatically extending underwater. Comprising a bow and stern spraying outer sleeve, an outboard spraying inner sleeve nested in the upper half part of the interior of the bow and stern spraying outer sleeve, and a coaxial reverse power mechanism used for sucking seawater into the bow and stern spraying outer sleeve and the outboard spraying inner sleeve at the same time so that the seawater can be sprayed out from the broadside and the bow and stern direction at the same time. According to the marine pirate prevention near-board berthing device, the coaxial reverse power mechanism is arranged in the injection pump, so that the synchronism of the rotating speeds of impellers in the bow and stern injection outer sleeve and the outboard injection inner sleeve can be guaranteed, the whole marine pirate prevention near-board berthing device is prevented from rotating due to torque, the static stability of the whole marine pirate prevention near-board berthing device in the vertical direction is guaranteed, and the service life of the marine pirate prevention near-board berthing device is prolonged. Therefore, the return performance of the device after being inclined by waves is improved.
本发明公开了一种吸口长度在水下自动伸长的喷射装置,包括艏艉喷射外套筒、嵌套在艏艉喷射外套筒内部上半部分的舷外喷射内套筒、以及用以同时向艏艉喷射外套筒和舷外喷射内套筒内吸入海水以使海水从舷侧和艏艉方向同时喷射出的同轴反转动力机构。本发明通过在喷射泵内设置同轴反转动力机构,可以保证其艏艉喷射外套筒和舷外喷射内套筒内叶轮转速的同步性,防止整个船用防御海盗近舷靠泊装置因扭矩产生自转,保证整个船用防御海盗近舷靠泊装置在垂直方向的静稳定性,从而提高了其受波浪倾斜后的回正性能。
