A deformable life buoy based on conductive shape memory polymer

Abstract

The invention relates to a conductive shape memory polymer based deformable life buoy. The conductive shape memory polymer based deformable life buoy comprises a life buoy body, a sealing end cover, apower supply device, an insulated and isolated coating, a charging hole, a switch, a pulling rope and a wire guide tube, wherein the life buoy body comprises an outer layer which is prepared througha conductive shape memory polymer, filled soft pore-closed foams, the wire guide tube and a flexible wave-formed plastic tube; the vitrification transformation of the conductive shape memory polymer is performed at 30-80 DEG C; the life buoy body can be deformed by shrinking the outer layer through the pulling rope under pre-deforming temperature. According to the conductive shape memory polymer based deformable life buoy, the size can be changed by pre-deforming, so that people with different body forms can use the life buoy, and a great number of life buoys can be conveniently stored and carried; and meanwhile, a fluorescent agent is added, so that the conductive shape memory polymer based deformable life buoy can be lighted at night, and thus the probability that drowning men using thelife buoys are found and rescued at night is obviously increased.

Description

technical field [0001] The invention relates to a lifesaving buoy, in particular to a deformable lifebuoy. Background technique [0002] The lifebuoy is a kind of water lifesaving equipment, which is widely used, and is designed for ship shipping, water operations, flood fighting and disaster relief, and water tourism and leisure activities. The carrying mode of the solid life buoy is usually hung on both sides of the hull, which occupies a large area, and the number of spare life buoys on board is limited, which often cannot meet the needs when encountering an accident. At present, the size of solid life buoys on the market is certain, which is inconvenient for thin people. When holding the life buoy for a long time on the water and waiting for rescue, they fall into the water due to lack of physical strength. For night search and rescue on the water surface, the existing life buoys all have fluorescent bands on the ring body, which is conducive to searching for persons in...
