The invention discloses a simple sea survival airship. The body structure of the simple sea survival airship is formed by an air sac and a pod, wherein the air sac is filled with
helium to provide
buoyancy, and the pod is suspended on the sea surface; the simple sea survival airship is provided with a wind surf, a
rudder, an operation board, a medical box for providing
emergency treatment articles, a wind-power and solar-energy dual
power generation system, a
seawater desalinating device, a storage cabinet for storing necessary food and tools and a foldable
bed for providing a rest area, wherein the wind surf, the
rudder and the operation board can adjust the direction of the airship, and the airship advances in the favorable direction through a positioning device; the wind-power and solar-energy dual
power generation system is used for supplying power to an
electric warmer and converting power energy into
heat energy for supplying heat; the
seawater desalinating device is used for filtering
seawater into drinkable
fresh water through a
reverse osmosis membrane under driving of the power energy. The simple sea survival airship is simple in structure and convenient to operate, and can rapidly provide a safe place capable of eluding
sea waves and sea
biology infringements, capable of positioning and navigation, warming and capable of supplying food and
medicine for persons in distress after sea perils occur, rescue
waiting time is prolonged, and the
survival rate of the persons in distress is increased.
