Water-air dual-purpose unmanned aerial vehicle

Abstract

The invention discloses a water-air dual-purpose unmanned aerial vehicle which comprises a vehicle body, a plurality of rotor wings, a water propelling propeller, an air tail propelling propeller and an air bag assembly, the vehicle body comprises a vehicle body, a differential horizontal tail and two wings, the differential horizontal tail is located at the tail of the vehicle body, the two wings are symmetrically arranged on the vehicle body, and at least one through hole is vertically formed in the upper wall of each wing; the rotor wings are coaxially arranged in the through holes in a one-to-one correspondence manner; the water-propelled propeller is mounted below the tail part of the fuselage and is positioned behind the differential horizontal tail; the aerial tail thrust propellers are mounted on the fuselage and located between the differential horizontal tails and the wings; the air bag assembly is located in the fuselage and comprises an air bag and an inflation and deflation mechanism which are connected with each other, and the inflation and deflation mechanism is used for achieving inflation or deflation of the air bag. The unmanned aerial vehicle can realize underwater, water surface and aerial operation, is agile in operation, fast in sailing speed and lasting in cruising ability, can carry different detection devices, and is high in flexibility, wide in application range and high in safety.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicles, and in particular relates to a water-air dual-purpose unmanned aerial vehicle. Background technique [0002] Traditional artificial underwater operations are very complicated, and personal safety cannot be completely guaranteed. As human underwater activities become more and more extensive, the application of underwater unmanned systems is becoming more and more popular. The underwater rotor UAV is applied because it can take off and land vertically on the water surface, navigate underwater and fly in the air, but its endurance and air flight or underwater / surface navigation speed limit its application field. [0003] A Chinese patent with application publication number CN105799891A proposes a water-air drone, which includes: a casing, four driving parts and a controller for controlling the driving parts are arranged on the casing, and the driving part includes a motor and is driven by th...

Problems solved by technology

[0004] However, the above scheme has the following disadvantages: 1) Because there are four driving parts, and the underwater resistance is greater than that in the air, and the operation of the UAV depends on the four driving parts at the same time, which greatly reduces the life of the UAV. ; 2) Because there are multiple propellers, it is not sensitive enough to operate underwater, and the navigation speed is slow
