Abstract

The present invention provides a self floating maritime rescue device based on Beidou positioning, comprising an inflatable floating mechanism, a folding stretcher mechanism, a rescue fixing mechanism, and a lifting hook. Two side telescopic rods are respectively installed inside the side telescopic rods, and one end of each side telescopic rod is equipped with a stretcher handle. One end of each stretcher handle is connected to a buckle, and two limit balls are installed inside both ends of each side telescopic tube. This design solves the problem of the original self floating maritime rescue device being bulky and difficult to install. The side telescopic rods, stretcher handles, connecting buckles, and side telescopic tubes are all made of carbon fiber and SUS316 The stainless steel material solves the problem of salt spray corrosion on the connecting parts of the original self floating offshore rescue device after prolonged use at sea. Compared with the existing technology, the present invention has a reasonable structure, is easy to assemble and install, and has high reliability.
