Technical Field

The invention belongs to the technical field of ships, and particularly relates to an amphibious vehicle and ship with a telescopic wheel paddle mechanism.

Background

An amphibious vehicle and boat is a vehicle which can travel on land and can also navigate on water. Because the amphibious underwater vehicle has better water path amphibious capability, the amphibious underwater vehicle is suitable for various fields such as civil use, military use and the like, and plays an important role. Most amphibious ships at present 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 vehicle and ship is relatively complex, the number of devices is large, the arrangement on the ship body is relatively dispersed, the main scale of the ship body is enlarged, and the weight is relatively large. The amphibious vehicle and ship are more complicated to operate, and need to be switched back and forth between two sets of power propulsion systems.

In the invention, the propulsion device adopting the telescopic wheel paddle mechanism adopts paddle propulsion when sailing on water, and the paddle retracts into the tire when sailing on land to propel like a solid tire. The amphibious ship adopts the same set of power propulsion system and is driven by a single power, so that the power propulsion system of the amphibious ship is simpler in structure and simpler to operate, the size and the weight of the amphibious ship are reduced, and the economy is improved.

The chinese patent application publication No. CN204547629U, entitled "an amphibious walking device", discloses an amphibious walking device that realizes two kinds of motions in water and land, and the technical scheme mainly introduces the overall design of an amphibious walking device. The propulsion device structure of the amphibious ship is different from that of the amphibious ship with the retractable wheel-propeller mechanism, the retractable paddle is arranged at the wheel hub of the tire, when the amphibious ship sails on water, the paddle extends out of the tire to form a paddle wheel structure, and the ship is propelled in a paddle wheel mode. When the amphibious vehicle and ship runs ashore, the paddle retracts into the tire and is converted into solid tire propulsion, so that the amphibious vehicle and ship has better stability, higher comfort level and capability of advancing under high load.

Disclosure of Invention

The invention aims to provide an amphibious ship with a telescopic paddle mechanism. The propulsion device of the retractable paddle mechanism is a propulsion device integrating water propulsion and land drive. When the amphibious ship enters water, the paddle extends out of the hub, the amphibious ship is pushed to sail in a paddle wheel propelling mode, when the amphibious ship goes ashore, the paddle of the paddle wheel retracts into the tire, the amphibious ship is driven to run by adopting solid tire propelling, and the same power propelling system is used for water propulsion and land propulsion.

The purpose of the invention is realized as follows:

Detailed Description

The invention aims to provide an amphibious vehicle and ship with a telescopic wheel paddle mechanism, wherein the amphibious vehicle and ship realizes the conversion of water/land propulsion functions through the telescopic wheel 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 high load. When the amphibious ship disclosed by the invention sails on water, the blades extend out of the tires to form a paddle wheel structure to push the amphibious ship to advance, and the contraction length of the blades is controlled by the hydraulic mechanism according to the water depth of a navigation area so as to adapt to the special requirements of the terrain of a shallow water area; when the amphibious ship runs ashore, the paddles retract into the tire, and the amphibious ship is driven to advance in a solid tire mode. The amphibious ship disclosed by the invention realizes the functions of water propulsion and land driving by using the same set of power propulsion system, and solves a series of problems of complex structure, complex operation, heavy weight and the like caused by the fact that most of the existing amphibious vehicles and ships adopt two sets of power propulsion systems.

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

the invention provides an amphibious ship with a telescopic paddle mechanism, which consists of a ship body 5 and a propelling device of the telescopic paddle, and is characterized in that: when the amphibious ship sails on water, the blades 3 extend out of the tires to form paddle wheels to push the amphibious ship to advance; when the amphibious ship is driven ashore, the blades 3 retract into the tires, the amphibious ship is driven to advance in a solid tire mode, and a set of power propulsion system is used for water propulsion and land propulsion.

The design of telescopic blades is adopted, the propelling mechanism is connected with the ship body at the head and the tail of the ship, and the solid wheel 1 and the rotating wheel 2 are connected by the hub 4.

Referring to fig. 1 to 5, when the amphibious ship sails on water, the hydraulic mechanism controls the paddle 3 to extend out of the hub 4, the solid wheel 1, the rotating wheel 2 and the paddle 3 form a paddle propulsion structure, the rotating wheel 2 is driven to rotate by the power propulsion system to drive the paddle 3 to rotate, and the paddle 3 rotates to hit water and is driven by the reaction force of water to drive the amphibious ship 5 to sail. When the amphibious ship goes ashore, the hydraulic mechanism retracts the blades 3 into the hub 4 to form a solid tire to push the amphibious ship 5 to advance.

In order to achieve the purpose, the invention adopts the following technical scheme:

1. the propulsion device of the telescopic paddle mechanism is divided into a bow part and a stern part. The ship head and tail wheel propeller device is composed of 2 solid tires 1, a wheel hub 4 structure which runs through the solid tires and has a supporting function in 2 groups of rotating wheels 2 and 2, and 2 telescopic groups of blades 3 which are distributed on the periphery of the solid tires 1. The whole propulsion device is symmetrical left and right, and the space between the stern propulsion device structures is slightly larger than that between the bows.

2. Paddle 3 on the advancing device adopts collapsible paddle wheel form, evenly distributed on runner 2 to through hydraulic structure control paddle 3 shrink length, special topography requirements such as adaptation shallow water district, shoal.

3. Solid tires 1 are arranged on the left side and the right side of the propelling device, and foaming materials are filled in the tire structures so as to meet the operation requirements of high load, bad terrain and the like.

4. A telescopic paddle 3 is arranged in a solid tyre hub 4 of the propulsion device, water enters the propeller to stretch out, and the propeller retracts ashore.

5. The extension and retraction of the blades 3 on the propulsion device are controlled by a hydraulic mechanism on the ship through an internal channel of the runner 2.

6. The thickness of the blade 3 structure on the propelling device is smaller than that of the hub 4 structure so as to be telescopic.

7. The propulsion device adopts the same set of control and power system drive for sailing in water and sailing on the shore.
