The invention adopts a large-diameter main culvert coaxial counter-rotating dual-rotor or a fan body to bear the main hoisting force, wherein multiple small-diameter auxiliary culvert rotors or fans are horizontally and symmetrically arranged at the periphery of the dual-rotor or the fan body; connecting arms of the rotors or fans can stretch and contract, twist and swing to carry out four degree-of-freedom actions, bear the auxiliary hoisting force, carry out direction control and serve as vertex prevention rings; a main side spout and a plasma energy wave generator vertex prevention ring are arranged on a main culvert; and a variable inertia system is arranged on the main rotors to realize the ability of preventing turbulent flow from changing into twisting wind. The slurry and flood current overhead-hoisting rescue method is competent for the overhead-hoisting rescue mission and can be combined with the slurry and flood current overhead-hoisting rescue amphibious medical ambulance to constitute a special overhead-hoisting rescue amphibious vehicle. Slurry current propellers such as an extension-type swing conical-head spiral front wing long roller floating type or gyro helix front wing floating head type, a crushing roller front wing floating type and a herringbone one-sided jagged-grain hub telescopic front wing crushing roller tire boosters are arranged at the four corners of a machine frame of the amphibious medical ambulance, so that the amphibious medical ambulance has the capability of floating and driving in the slurry current, and the design method of the slurry flood current special rescue method and the amphibious medical ambulance is solved.
