UAV with rotor diversion and wear-resistant structure used in wind and sand environment

Abstract

The invention discloses an unmanned aerial vehicle with a rotor diversion and wear-resistant structure for use in a sandstorm environment, comprising an unmanned aerial vehicle body and a frame, and the unmanned aerial vehicle body is arranged in the middle of the frame. The drone includes a rotor mechanism, the rotor mechanism is arranged on the frame, and the rotor mechanism is evenly arranged around the drone body. The rotor mechanism includes a main shaft, a first rotor, a secondary shaft, a second rotor, a casing tube, a main bearing, an auxiliary bearing, a connecting rod and a speed-adjusting transmission mechanism. The main shaft is arranged at the top of the frame in a vertical direction, the first rotor is arranged on the lower end of the main shaft, the auxiliary shaft is arranged parallel to the side of the main shaft away from the drone body, the second rotor is arranged at the upper end of the auxiliary shaft, and the second rotor is arranged at the upper end of the auxiliary shaft. The rotor and the outer casing are fixedly connected by a cross bar, the main bearing is respectively penetrated at the end of the main shaft away from the first rotor, the auxiliary bearing is respectively penetrated at the end of the auxiliary shaft away from the second rotor, the connecting rod is arranged in the horizontal direction, the main bearing and the auxiliary The bearings are connected by connecting rods, and the speed regulating transmission mechanism is respectively arranged on the main shaft and the auxiliary shaft.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle equipment, in particular to an unmanned aerial vehicle with a rotor diversion and wear-resistant structure used in a sandstorm environment. Background technique [0002] Compared with manned aircraft, UAVs have the characteristics of small size, low cost, and convenient use. They play an important role in both military and civil applications. The development of UAVs is becoming more and more extensive. Commonly used delivery drones, aerial photography drones, environmental monitoring drones, etc., play a significant role in human daily life, helping humans complete high-risk actions to achieve their goals. In addition, with strong adaptability and survivability, UAVs can be applied to a variety of harsh environments, such as wind and sand environments. [0003] There is no doubt that in the sandstorm environment, the air that the drone comes in contact with will carry different co...

Problems solved by technology

First of all, when the direction of the dust and the rotor of the UAV is inconsistent, there will be a relative collision, which will cause damage to the surface of the rotor; secondly, if the dust enters the joint between the rotor and the UAV body, there will be friction between the dust and the rotor , so that the rotor is worn
