Abstract

The invention discloses a water-air amphibious propelling device which comprises a power device and a deformation device, the power device comprises four water-air dual-purpose propellers, and the four propellers are installed on an aircraft body needing power through the deformation device in a pairwise mode. The propelling form of the power device can be changed through the deformation device, so that the aircraft can be switched between water and air; the deformation device comprises two tilting mechanisms and a translation butt joint mechanism for changing the front-back distance between the two tilting mechanisms, each tilting mechanism is provided with a pair of propellers, and the propellers on the two tilting mechanisms correspond to each other in the front-back position; the tilting mechanism is used for driving the propelling angles of the corresponding pair of propellers, and the propelling angles change between a vertical propelling state and a horizontal propelling state; the distance between the two tilting mechanisms is changed through the translation docking mechanism, so that the front and back corresponding propellers are coaxially docked to form a contra-rotating propeller structure, and the propelling efficiency of the propelling device during water surface navigation is improved.

Description

technical field [0001] The invention belongs to the technical field of propulsion devices, and in particular relates to an amphibious propulsion device. Background technique [0002] The amphibious unmanned aerial vehicle has the characteristics of high maneuverability and high endurance performance, which has attracted more and more attention, and more and more are put into application. In the field of piloting, unmanned aerial vehicles undertake the work of piloting sea areas on water and underwater at the same time, as well as taking images, transmitting information and even hydrographic mapping. In recent years, multi-rotor UAVs, especially quad-rotor UAVs, have become the mainstream of amphibious UAVs due to their convenient maintenance and simple structure. However, the existing amphibious unmanned vehicles are mainly divided into two types. One is a vertical take-off, land-water and land-based amphibious ground-effect aircraft with the publication number of CN1109796...
