A multi rotor UAV, which belongs to the technical field of unmanned aircraft, including the fuselage, machine arm, motor, rotor, tripod, machine arm connected on the fuselage, the machine arm is installed on the motor rotor is connected to the motor, the tripod is arranged at the following, in addition, there are also arranged on the arch of multi rotor UAV. Arch of the lower end is connected to the machine arm, the arch is also provided with a magnet. When in use, can through the magnetic arch above the magnet to the multi rotor UAV adsorbed on the iron object height, such as the adsorption of traffic signs in the bar work. The multi rotor UAV in the adsorption state does not need battery power to provide lift, and can greatly prolong the working time of the airborne working equipment during a take-off and landing process. The invention discloses a multi rotor unmanned aerial vehicle (UAV), which can be widely applied to the field of fixed-point surveillance, surveillance, shooting, traffic management, urban management and other fields.

一种多旋翼无人机
本专利技术涉及无人飞行器
,具体涉及一种多旋翼无人机。
技术介绍
多旋翼无人机通常有3~9个旋翼,尤其以4旋翼最为常见。多旋翼无人机具备垂直起降、空中悬停、低速飞行、倒飞、侧飞、360度旋转等功能,现已在近地航拍(空中拍照、摄像)、监控、侦察、无线电信号中继,高压线、大桥、水坝和路面检査,搜索与救援,运送快递等方面得到应用。现有的多旋翼无人机主要有以下不足:由于在空中悬停时依靠机上装载的电池来提供电能,因此续航时间短,大多数依靠电池电能工作的多旋翼无人机一次只能持续飞行10~30分钟左右,也就是说多旋翼无人机在空中工作的时间一般只有10~30分钟,远远不能满足人们使用多旋翼无人机来进行长时间空中监控、拍摄、喊话、传输、信号中继、布防、待命等实际需求。另外,现有的多旋翼无人机在空中悬停进行定点监控、拍摄时,其姿态受风力以及位置传感器信号影响较大,稳定性不易保证;多旋翼无人机在空中悬停工作时,飞控系统需要对其姿态进行实时控制和调整,既消耗电池的电能,也存在不小的安全隐患,万一发生机械、电控故障或操作不当,就很容易造成坠机事故(炸机),甚至从空中 ...
