[0014] Compared with the prior art, the ship lifeboat collecting and releasing device has the following beneficial effects:

[0015] Two movable rings are secured together by chains using an airbag. A cable is passed over a roller and attached to the lifeboat. The hydraulic press is activated, driving a rotating frame via a hydraulic cylinder. This allows the rotating frame to extend or retract into the vessel, rotating the lifeboat. External machinery then operates the cable, which in turn raises and lowers the lifeboat. During deployment and stabilization, the lifeboat is affected by sea winds, causing one side to compress the airbag. The airbag moves one rotating plate, which in turn moves another rotating plate via a chain. These rotating plates then move a second sliding block. The second slider moves the moving column, which in turn moves the first slider, which in turn moves the moving plate. The moving plate then sends gas from the air tank into the compressed airbag through the connecting pipe. This cushions the lifeboat's swaying and squeezing, preventing damage to the lifeboat and equipment during deployment and retrieval exercises due to swaying and scraping. This also affects the lifeboat's lifespan and safety. Changing the distance between the two moving rings alters the distance between the two rotating plates, allowing the device to adapt to different sizes and models of lifeboats, thus expanding its applicability and practicality.
