Amphibious recreational vehicle

An amphibious recreational vehicle (motorhome, trailer, SUV, and the like) of conventional RV height, width, and length restricted dimensions necessary to travel on highways and roads, and which upon entering the water, the bottom of the vehicle expands outwardly and upwardly to form a fast planing, wide-beam, ground effects cathedral type double-tunnel hull. The hull makes use of a dynamic air cushion to augment the planing of the hulls, owing to the ground effect created by compression of the ram air stream (and water vapor) rushing through the two tapered tunnels separating the three hulls. The wheels of the vehicle are simultaneously raised out of the water to eliminate parasite drag. The resultant hull is substantially wider than the cabin, providing substantial ocean-going stability for the craft. The folded elements incorporated within the cabin rooftop, raise upward to form a traditional yacht flying bridge, complete with a windshield, steering station, seating, mast, and safety rails. The resultant watercraft closely approximates the off-shore speed, seaworthiness, performance, stability, cabin space, main deck space, and elevated flying bridge deck attributes of conventional yachts. And when on land, the craft is a fully functioning traditional recreational vehicle suited for fast highway travel, driving about towns, staying in RV parks, and camping in the wilderness. This amphibious recreational vehicle is an interrelated component divided from the inventor's previous Comprehensive Vehicle Construction And Hybrid Electric Drive System application.

Multimode bionic amphibious robot

The invention provides a multimodal amphibious bio-robot, which comprises a head, a replaceable wheel paddle/flipper mechanism, a propelling unit and a caudal peduncle compound drive mechanism. In water, the propelling unit and the caudal peduncle compound drive mechanism oscillate back and forth to propel by imitating a fish in the plane, and a rotating mechanism rotates the propelling unit and the caudal peduncle compound drive mechanism for 90 degrees, and switches the moving mode of propelling by imitating a fish into that of swimming by imitating a dolphin; and the flipper mechanism assists the tail propelling to accomplish actions of moving forward, moving backward, turning and pitching, and the paddle mechanism assists the robot turning. On land, the flipper mechanism rotates continuously to make the robot creep on the ground, imitates the movement of a wheel mechanism when rotating continuously, thereby the robot improves the speed of the movement, has obstacle-climbing capability, and a driven wheel reduces the resistance of the movement on the land. The robot can induce the own environment in real time by two liquid level sensors arranged at the head and the propelling unit respectively; and when the land and water environments are changed, according to the information of the liquid level sensors, a main control panel uses corresponding movement policies to accomplish the intelligent switching between the modes of moving on the land and in the water.

Slurry and flood current overhead-hoisting rescue method and amphibious medical ambulance

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.
