Unmanned aerial vehicle flight collision-prevention device

Abstract

The invention discloses an unmanned aerial vehicle flight collision-prevention device and aims to solve the problem that in the prior art, there are not protective measures for blades during flight ofan unmanned aerial vehicle and accordingly collision with tree branches possibly occurs to cause damage. Currently, the following scheme is proposed that the unmanned aerial vehicle flight collision-prevention device comprises a device body, the outer wall of the device body is arrayed and welded with four horizontally arranged installing rods, the sides, away from the device body, of the tops ofthe installing rods are provided with blades, the sides, close to the device body, of the tops of the installing rods are welded with supporting rods arranged in the vertical direction, the tops of the supporting rods are welded with first casing pipes, each first casing pipe is movably sleeved and connected with two first movable rods, the ends, away from the first casing pipes, of the first movable rods are movably sleeved and connected with second casing pipes, the tops of the first casing pipes and the tops of the second casing pipes are both welded with two sleeves. The unmanned aerial vehicle flight collision-prevention device is novel in design, simple in structure and capable of making adjustment to prevent baffles and fixing rods from blocking the blades, accordingly can preventcollision between foreign objects and the blades and improve the safety of the blades.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an anti-collision device for unmanned aerial vehicles. Background technique [0002] Unmanned aircraft, referred to as "unmanned aerial vehicle", or "UAV" in English, is an unmanned aircraft that is controlled by radio remote control equipment and its own program control device, or is completely or intermittently operated autonomously by an on-board computer. [0003] Nowadays, many photography enthusiasts like to use UAVs to fly into the air for aerial photography. For UAVs without fixed wings, the rotation of the fan blades is used to provide energy saving during flight. Therefore, the safety of the fan blades is very important for the safety of UAVs. Flight safety is very important. However, when taking aerial photography in the woods, since there are no protective measures for the fan blades of the drone, and there are many branches in the woods, the operator...
