Aspects of the present disclosure generally pertain to an amphibious vehicle (or amphibian) that is viable on land as well as on water. Aspects of the present disclosure more specifically are directed toward an amphibious vehicle that employs hydrofoils and other features, for example, for efficient cruising when in water. The amphibious vehicle may be embodied as a personal amphibious vehicle.

A transmission for a vehicle, particularly a skid-steered vehicle, that employs motive power from a prime mover delivered through an input shaft to drive left and right drive shafts at a nominal speed and input power from an electric motor to vary the speed of the left and right drive shafts according to steering commands from a steering control structure. The speed of the left and right drive shafts is directly related to a speed of the input shaft and the nominal speed of the left or right drive shaft is varied upwardly or downwardly by a ratio of the speed of the steering shaft via a speed varying structure. The speed of the left and right drive shafts is simultaneously varied in opposite directions (i.e. upwardly and downwardly) relative to the nominal speed by an equal number of rotations.

A combination of a marsh buggy is coupled with a modified skid steer. The skid steer has a frame, and hydraulic lines for attaching to hydraulic driven motors for driving a track or wheeled drive system. The skid steer further having an engine and a hydraulic system, including a pump and hydraulic tank, and valves; an operator's cab positioned on the frame, said operator's cab further comprising a set of hydraulic controls connectable to the hydraulic system for controlling the drive system and a hydraulically driven lift system, including two booms, each boom comprising a first arm and a second arm, the first arm being pivotably mounted to the frame, the second arm being telescopically coupled to the first arm by a hydraulic cylinder controllable from the operator's cab. The marsh buggy includes a first and a second floatable pontoons, the two pontoons coupled together in a parallel but offset relationship. Each pontoon has an endless track including a chain and treads coupled around the periphery of each respective pontoon, and a series of sprockets coupled to the chain on each pontoon; each sprocket connected to a hydraulic motor. The marsh buggy further has hydraulic motors and drive sprockets coupled to the hydraulic system for driving the endless track. The skid steer is mounted on the marsh buggy, between the two pontoons, and the hydraulic motors of the marsh buggy are operationally coupled to said hydraulic system of said skid steer so that said hydraulic controls in said cab are operationally connected to said hydraulic motors to control the drive system on the marsh buggy.

A drilling platform for amphibious operations includes: a base, wherein drive tracks are arranged on both sides of the base, a propeller is disposed at a rear end of the base, and a driving assembly is disposed inside the base; two support cylinders are respectively disposed at two ends of the base; each of the support cylinders contains a sub-cylinder; a pushing cylinder is arranged on a bottom surface of the partition plate; a buoyancy adjustment assembly is provided at a bottom of the base, so as to provide buoyancy support for the base when the base is transferred from land to water. The present invention is suitable for drilling construction of pile foundations of water and land buildings, bridge piers, and transmission line electric tower pile foundations, as well as drilling of oil wells, wherein the drilling platform construction process at different drilling points is omitted.

An amphibious platform vehicle-vessel to support and to move hydraulically operated and controlled earth-moving and lifting equipment, such as excavators and cranes, on solid ground, semi-solid or marshy ground, shallow water, and deeper water. The modular units can be transported to a worksite on separate trailers and assembled and reconfigured on site. Two compartmented pontoon units are mounted to an adaptive cross member that can accommodate different types of moving-lifting equipment through different mounting flanges, and to auxiliary cross members. Propulsion is provided through amphibious cleats on drive chains in chain tracks driven by dual-motor driving drums and over a tension-adjusting passive chain roller, surrounding a sealed pontoon shell internally reinforced with bulkhead partitions, beam shell-bottom stiffeners, and pressed-angle shell-bottom stiffeners. An extendable auxiliary float can be extended outward from each compartmented pontoon for increased stability in floating operations. Spud units having a chain-drive spud and a spud-driving mount unit with spud-mount wear strips are hydraulically raised and lowered by a spud-driver motor at the command of the equipment operator using a spud-control switch.

A method for deploying a payload at a subaquatic deployment location includes submersing a submersible aquatic vehicle in a body of water. The submersible aquatic vehicle carries a payload. The method also includes driving the submersible aquatic vehicle to a deployment location under the body of water while the submersible aquatic vehicle carries the payload in a first position. The method additionally includes at the deployment location, moving the payload from the first position to a second position. The method further includes deploying the payload from the second position to a deployment position at the deployment location.

A multihull stepped planing boat with multiple independent elastic planing surfaces includes: a main hull, X front planing sub-hulls arranged side by side under a front portion of the main hull, and Y rear planing sub-hull arranged side by side under a rear portion of the main hull; wherein X and Y are positive integers, and 3≤X+Y≤8; the X front planing sub-hulls are equally spaced, and the Y rear planing sub-hulls are also equally spaced; there is a gap between the X front planing sub-hulls and the Y rear planing sub-hulls. The planing surface of the main hull is formed by a plurality of independent and spaced sub-planing surfaces. There is a certain elastic buffer space between each sub-planing surface and the main hull, and the shock absorption structures can absorb most of the shocks, thereby reducing the impact of water surface waves during high-speed navigation.
