Water jet propulsion wheel type amphibious unmanned ship

Abstract

The invention discloses a water jet propulsion wheel type amphibious unmanned ship which is characterized by comprising a ship body, a battery pack, a water jet propulsion device and a wheel type walking device. The battery pack, the water jet propulsion device and the wheel type walking device are arranged on the ship body; the wheel type walking device comprises a drive unit, at least one frontwheel drive unit, a pair of back wheel drive units, at least one tire steering unit and a tire reeling unit; the front wheel drive unit and the back wheel drive units are rotatably arranged on corresponding positions of the front side and the back side of the ship body; a tire is rotatably arranged on the front wheel drive unit through the tire steering unit; a tire is rotatably arranged on each back wheel drive unit; an output shaft of the drive unit is connected with input shafts of the front wheel drive unit and the back wheel drive units; output shafts of the front wheel drive unit and theback wheel drive units are connected with axles of the tires; and the tire reeling unit drives the front wheel drive unit and the back wheel drive units to rotate around rotation axes of the tire drive units. The water jet propulsion wheel type amphibious unmanned ship provided by the invention has a favorable shallow water through capacity aiming at the shallow water environment.

Description

technical field [0001] The invention belongs to the technical field of amphibious unmanned ships, in particular to a water-jet propulsion wheeled amphibious unmanned ship. Background technique [0002] An unmanned ship is a surface autonomous robot with small size, shallow draft, and flexible maneuverability. It can enter shallow water areas that are difficult for traditional large ships to reach. At present, it has been widely used in many fields such as environmental monitoring, aquaculture, and security patrols. However, for some special water environment, such as swamps and tidal flats intertwined with waterways, or coastal intertidal zones with water during high tide and no water during low tide, it is difficult for unmanned ships with traditional ship design to enter and operate, resulting in monitoring blank areas and blind spots for unmanned ship operations. [0003] At present, amphibious ships mainly have two layout forms: tracked and wheeled: [0004] Crawler-ty...

AI Technical Summary

Problems solved by technology

[0007] Aiming at the shortcomings of the existing surface ships including unmanned ships that cannot enter special working environments such as swamps, tidal flats, and intertidal zones, the present invention proposes an amphibious unmanned ship that uses a combination of wheeled walking mechanism and water jet propulsion to make up for the above-mentioned areas. The blank area of ​​monitoring and the blind area of ​​unmanned ship operation can not only sail at high speed in the water but also land on the beach, and the maneuverability is greatly improved
