From the current state of the boat retraction technology, the main modes of retraction technology include side-hanging retraction, stern slideway retraction and hull dock retraction. Compared with a side-mounted lifting type retraction mode, the two latter modes are required to be under stronger constraint on a specific ship type part or a stern molded line of a ship body, and the retraction device usually needs to rely on an additionally arranged electromechanical system to complete necessary actions such as an access slide way, a hook locking, a tripping unlocking and the like. According to investigation, the side-hanging type retractable device is one of the most widely applied modes at present, can be divided into a single-hanging-point type retractable device and a double-hanging-point type retractable device, is suitable for the side-belonging application of various water-surface ships, civil ships and other special ships, and has low restriction on the ship structure and molded line design. The jack is typically implemented by a rigid frame-like recovery structure filled with buoyancy material, with the boat being deployed to the surface or recovered from the water to the boat by a side boom. The general hanging type retraction device mainly comprises a rigid frame structure conformal with a retraction boat, and has the defects of high requirements on the accuracy of butt joint operation, dependence on manual operation for unhooking and the like although the structure is simple and reliable. The outboard hoisting type hoisting device is limited by the hoisting capacity, electrohydraulic feeding capacity and other restrictions, and the hoisting type hoisting device of the outboard part is difficult to be additionally provided with an electromechanical system commonly used in a stern slideway type hoisting device and a ship body dock type hoisting device to assist in completing key actions such as docking guidance, unhooking and the like. Therefore, under the auxiliary operation without depending on an additional electromechanical system, the existing rigid frame type hanging and releasing recovery mechanism faces the outstanding problems that the recovery guiding operation precision requirement is high, the boats are easy to generate hard collision and hard contact collision with the rigid frame, the unhooking relies on manual operation and the like in practical application, and the technical requirement of safe and efficient arrangement and recovery of the boats under complex and changeable sea condition environments is difficult to adapt.

According to the invention, the boat retraction device reduces the requirements of guiding, controlling precision and manpower participation of boats from the retraction system side aiming at complex sea conditions, improves the recovery success rate, has strong adaptability, and has universality and suitability for automatic deployment and recovery of boats.
According to the boat retraction system, the curved surface guide plates on the two sides of the main body support frame are opened and closed, the anti-falling connecting rod assemblies are automatically lifted, the positions of the self-locking devices are locked, the anti-rolling support plate is used for stabilizing the water and supporting the water and the water, and the whole recovery process of automatic locking after the boat is successfully docked from the beginning to the successful docking is realized through the curved surface flexible guide and double redundancy self-locking functions, so that the docking success rate is greatly increased.
The invention provides a ship retraction system based on curved flexible guide and double redundant self-locking, wherein a curved guide plate and guardrails on two sides are provided with rebound hinges, a buffer spring is arranged in the rebound hinges, a free rotation sleeve is sleeved outside a rod piece of a main body supporting frame part, and the ship can be effectively buffered and protected when the ship collides with the retraction system, so that the retraction system has better safety.
It will be readily appreciated by those skilled in the art that the foregoing description is merely a preferred embodiment of the invention and is not intended to limit the invention, but any modifications, equivalents, improvements or alternatives falling within the spirit and principles of the invention are intended to be included within the scope of the invention.
