Small propeller capable of enabling unmanned aerial vehicle to be more stable during wind receiving

Abstract

The invention relates to a small-sized propeller, in particular to a small-sized propeller capable of enabling an unmanned aerial vehicle to be more stable when receiving wind, which comprises a slotted guide cylindrical frame, a support frame with holes at four corners, an N-shaped slotted sliding block, a driving mechanism, a swinging mechanism and the like, the bottom face of the grooving guide cylindrical frame is fixedly connected with a four-corner-opening supporting frame, N-shaped grooving sliding blocks are slidably connected to the grooving guide cylindrical frame in a distributed mode, a driving mechanism is arranged on the grooving guide cylindrical frame, and the swing mechanism is slidably connected to the N-shaped grooving sliding blocks. The flight propeller variable-pitch mechanism and the gear holder with the long rod push the rotating ring and the device on the rotating ring to move downwards, so that the connecting rod drives the variable-pitch propeller to swing downwards, the angle of the variable-pitch propeller is deflected, the rotating efficiency of the variable-pitch propeller is improved, and the unmanned aerial vehicle can operate at different airflow flow speeds; and stable flight of the unmanned aerial vehicle is fully ensured.

Description

technical field [0001] The invention relates to a small propeller, in particular to a small propeller which can make the unmanned aerial vehicle more stable when exposed to wind. Background technique [0002] With the rapid development of UAV-related technologies at home and abroad, there are many types of UAV systems and distinctive features of wide application. UAV is an unmanned aircraft controlled by radio remote control equipment and self-provided program control device. UAV is actually a The general term for unmanned aerial vehicles, because unmanned aircraft is of great significance to future air combat, all major military countries in the world are stepping up the development of unmanned aircraft. [0003] UAVs need to conduct reconnaissance and surveillance over a wide area, and they need to fly in a high-altitude environment for a long time. Due to the large air flow in the high-altitude environment, the flight of the UAV will be unstable, unable to continuously ob...
