This invention relates to the field of marine equipment technology, specifically to a rapid release device for a passenger ship's life raft. The rope release assembly includes a connecting rope attached to a baffle, a fixing ring on a bracket, a locking ring fastened to the fixing ring, and a manual release mechanism connecting the locking ring to the end of the connecting rope. The locking ring also has a release device. The inflation release assembly includes a stop ring on a bracket, with a wide-pitch screw threaded inside the stop ring. The release device of the rope release assembly uses a built-in expansion material, which expands upon contact with water, allowing for rapid response when the ship is flooded without relying on hydrostatic pressure or manual intervention. Simultaneously, the inflation release assembly incorporates a linkage mechanism consisting of the stop ring, the wide-pitch screw, and a conical block, ensuring that the life raft's cylinder initiation of inflation is triggered when the rope extends to a set length, avoiding the problem of insufficient inflation due to short ropes in traditional structures.

The application discloses an unmanned ship recycling device, a recycling system and a recycling method. The unmanned ship recycling device comprises a crane module, a docking module and a control module. The crane module comprises a hoisting arm and a motion compensation arm, the working end of the hoisting arm is hinged to the connecting end of the motion compensation arm, and the working end of the hoisting arm and the motion compensation arm is respectively provided with a first pulley set and a second pulley set. The docking module comprises an electromagnetic connecting hook, a connecting male head and a traction rope. The control module comprises a central control unit and a first position sensor, and the first position sensor is located on the hoisting arm. The application realizes the automatic parking of the unmanned ship through motion compensation and relative motion compensation, and saves manpower. Precise positioning adjustment and positioning recognition device ensure the high efficiency of the unmanned ship recycling. The electromagnetic connecting hook and the connecting male head have effective grabbing and locking mechanisms, which improve the reliability and safety of operation, and also significantly improve the safety and efficiency of operation.

The invention discloses a split type recycling and laying device for an unmanned ship under high sea conditions. The split type recycling and laying device comprises a split type cradle structure. The split cradle structure comprises an upper-layer platform and a lower-layer cradle; the lower end face of the upper-layer platform is connected with the lower-layer cradle through a rope length adjusting device and four lifting chain slings; an accommodating space with an unmanned ship limiting device is arranged in the lower-layer cradle, and the accommodating space is used for parking an unmanned ship; the four corners of the upper end face of the upper-layer platform are each connected with a second sling, the upper ends of the four second slings are each connected with a sub-ring, the four sub-rings are connected to a hanging ring, and the hanging ring is used for being connected with a mother ship crane. The split type recycling and laying device for the unmanned ship under the high sea condition and the using method have the advantages of being stable and accurate in control, wide in applicability and easy to operate.

The utility model relates to the field of emergency lifesaving or rescue in seaborne or connected river and sea water areas, in particular to a lifeboat bearing and releasing system which comprises a lifeboat hanging hook rotationally connected to a lifeboat bow and a lifeboat stern, and a bearing stress point of an opening of the lifeboat hanging hook and a rotating circle center point of the lifeboat hanging hook are located on the same vertical line. An opening of the boat hanging hook is provided with a steel wire falling prevention structure forming enveloping with the opening, the boat bow and the boat stern of the lifeboat are respectively and vertically provided with a double-acting jack for driving the boat hanging hook to rotate around the rotating circle center, and the lifeboat is provided with an operating lever subsystem for controlling the double-acting jacks to act. A bottom plate of the lifeboat is provided with an internally-locked hydrostatic pressure unit subsystem which has a liquid level sensing function and is used for detecting whether the lifeboat falls onto the sea surface or the water surface or not. The system is beneficial to simplifying a boat hook system, and is safer and more reliable.
