Amphibious boat with shoal free passage capability

Abstract

Disclosed is an amphibious vessel provided with the capacity for free passing of a shoal. The amphibious vessel includes a hull and an air propeller power device mounted on a deck of the hull. Foldable wheels are arranged on the two side surfaces of the stern part of the hull symmetrically. Each foldable wheel includes a front wheel, a first electric pushing rod and a linkage mechanism. The firstelectric pushing rods drive the linkage mechanisms and drive front wheels to be extended out from the side surface of the hull or retracted back to the side surface of the hull through transmission ofthe linkage mechanism, and the bottoms of the front wheels after extending out from the side surface of the hull exceed downwards the bottom of the hull. The stern part of the hull is provided with afixed wheel. The fixed wheel comprises a back axle fixedly mounted on the hull. At least two back wheels are symmetrically and rotatably arranged the back axle in a sleeving mode. The bottoms of theback wheels exceed downwards the bottom of the hull. The amphibious vessel further comprises a device which can realize the backing function of the amphibious vessel, meanwhile, wheel structures are improved, using requirements of the amphibious vessel for the wheels are met, and the amphibious vessel has the capability of free passing of the shoal.

Description

technical field [0001] The invention relates to the technical field of air-propelled ships, in particular to an air-propelled amphibious ship capable of freely passing through shoals. Background technique [0002] Our country has a vast territory, and the climate and hydrology in the north and the south are very different, such as the rapids in the south and the dry and shallow water in the north, and the sediment movement and shoal evolution in river beds, lakes and coasts are still going on. In order to meet the needs of navigating in various forms of shallow water, beaches, swamps or tidal flats, various types of ships using air propeller engines as power systems have emerged, such as hovercraft, air-propelled amphibious swamp boats (Air boat), air-propelled Air-cushioned planing boats, etc., are generally referred to as air-propelled ships. However, these air-propelled ships are specially designed for specific needs, and generally cannot meet the needs of a ship type th...

Problems solved by technology

However, these air-propelled ships are specially designed for specific needs, and generally cannot meet the needs of a ship type that can simultaneously adapt to various forms of shoal areas such as shallow water beaches or gravel, swamps or tidal flats. Therefore, some units (such as geological Surveying, border patrol, etc.) urgently need amphibious ships that can meet the navigation requirements of various forms of shoal areas
