Abstract

The invention discloses an unmanned aerial vehicle with a waist-push power device, which comprises a body, wings and propellers. The fuselage and propellers are arranged on the belly. The propeller includes a first propeller, a second propeller, a first hub and a second hub. The belly is provided with an annular groove-shaped abdominal cavity. The first hub and the second hub are respectively installed on the cylindrical surface at the bottom of the abdominal cavity through bearings. The first The propeller is radially installed on the outer surface of the first hub, and the second propeller is radially installed on the outer surface of the second hub. The first hub and the second hub have opposite rotation directions and both take the center line of the body as the axis of rotation. The first propeller and the second The placement angles of the blades of the propellers are opposite; the opposite rotation directions of the first hub and the second hub are respectively driven by two motors or driven by one motor and reversed by a reversing assembly. A counterweight that can move along the center line is arranged inside the fuselage.

Description

technical field

[0001] The invention relates to the field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle with a waist-push power device. Background technique

[0002] UAV is an aircraft that is used more and more. According to the application field, UAV can be divided into military and civilian. In terms of military use, UAVs are basically reconnaissance aircraft and target drones. Military UAVs are mostly jet-type high-speed UAVs, which are expensive, and the fuel system limits their cruising capabilities and cannot fly for a long time. In terms of civilian use, there are more and more applications in aerial photography, agriculture, disaster rescue detection and delivery, wildlife observation, infectious disease monitoring, remote sensing mapping, meteorological data acquisition, power inspection, film and television shooting, etc.

[0003] In the prior art, most of the civilian UAVs come into contact with small four-blade vertical UAVs or large ...
