Description

Amphibious vehicle and vessel with telescopic wheel and paddle mechanism

Technical Field

Background

The amphibious vehicle and ship can travel on land and water. Because it has better water path amphibious ability, it is suitable for various fields such as civilian use, military affairs, etc., plays an important role. The current majority of amphibious ships adopt two sets of power propulsion systems to realize the functions of water propulsion and land driving, so that the propulsion structure of the amphibious ships is complex, the equipment is more, the arrangement on the ship is also scattered, the main scale of the ship is enlarged, and the weight is larger. The handling of amphibious vehicles and vessels is also more cumbersome, requiring switching back and forth between two sets of power propulsion systems.

In the invention, a propulsion device of a retractable wheel paddle mechanism is adopted, open wheels are adopted for propulsion when the ship sails on water, and paddles shrink back into tires for propulsion like solid tires when the ship runs on land. The amphibious ship adopts the same set of power propulsion system and is driven by single power, so that the power propulsion system of the amphibious ship has simpler structure and simpler operation, the size and weight of the amphibious ship are reduced, and the economy is improved.

An amphibious walking device for realizing amphibious motion is disclosed in a patent document with the publication number of CN204547629U and the name of amphibious walking device, and the technical scheme is mainly introduced to the overall design of the amphibious walking device. The structure of the propulsion device of the amphibious ship is different from that of the amphibious ship with the retractable wheel-paddle mechanism, the retractable paddles are arranged at the wheel hubs of the tires, and when the amphibious ship sails on water, the paddles extend out of the tires to form a paddle wheel structure, and the ship is propelled in paddle wheel mode. When the amphibious vehicle and the ship travel on shore, the paddle retracts into the tire and is converted into solid tire for propulsion, so that the amphibious vehicle and the ship have better stability, higher comfort and high-load forward.

Detailed Description

The invention aims to provide an amphibious vehicle and vessel with a telescopic wheel and paddle mechanism, which realizes the conversion of the water/land propulsion function through the telescopic wheel and paddle mechanism. The paddle of the telescopic wheel paddle mechanism is designed in a telescopic mode, and the whole wheel is in a solid rubber tire mode, so that the telescopic wheel paddle mechanism is suitable for running at low speed and under high load. When the amphibious ship sails on water, the blades extend out of the tire to form a paddle wheel structure to push the amphibious ship to advance, and the contraction length of the blades is controlled through the hydraulic mechanism according to the water depth of a navigation area so as to adapt to the special requirements of the topography of the shallow water area; when the amphibious ship runs on shore, the paddles retract into the tires and drive the amphibious ship to advance in the form of solid tires. The amphibious ship provided by the invention uses the same power propulsion system to realize the functions of water propulsion and land running, and solves a series of problems of complex structure, complex operation, heavy weight and the like caused by the adoption of two power propulsion systems by most amphibious ships.

The invention is described in detail below with reference to the attached drawing figures:

The retractable blade design is adopted, the propulsion mechanism is connected with the ship body from head to tail, and the solid wheel 1 and the rotating wheel 2 are connected by the hub 4.

With reference to fig. 1 to 5, when the amphibious ship sails on water, the hydraulic mechanism controls the paddles 3 to extend out of the hub 4, the solid wheel 1, the rotating wheel 2 and the paddles 3 form a paddle wheel propulsion structure, the rotating wheel 2 is driven by the power propulsion system to rotate, the paddles 3 are driven to rotate, and the paddles 3 rotate to hit water to be reacted by water to drive the amphibious ship 5 to sail. When the amphibious ship lands, the hydraulic mechanism retracts the blade 3 into the hub 4 to form a solid tire to push the amphibious ship 5 to advance.
