A multi rotor UAV, which belongs to the technical field of unmanned aircraft, including the fuselage, machine arm, motor, rotor, tripod, tripod arranged below the fuselage, the tripod is provided with a hook, and the tripod or / and door frame is provided with a magnet rotor. Multi rotor drones can be hung on high objects by hanging hooks on their tripods, or by magnets on a tripod or rotor shield. After hanging or adsorbing on a high object, the working equipment carried by the multi rotor UAV can work or stand on the high ground for a long time. The multi rotor UAV in suspension requires no battery power to provide lift, which can greatly extend the working time of the airborne equipment during a take-off and landing process. The multi rotor unmanned aerial vehicle can be widely used in the field of fixed-point surveillance, monitoring, shooting, environmental monitoring, field investigation, case reconnaissance, city management, yard security, express delivery, and other fields.
【技术实现步骤摘要】
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3~8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约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),甚至从空中掉下 ...
【技术保护点】
一种多旋翼无人机,包括机身、机臂、电机、旋翼、脚架,脚架设置于机身下面,在旋翼处通常还设有旋翼防护架,其特征是:在多旋翼无人机的脚架上设有挂勾,并且在脚架或/及旋翼防护架上还设有磁体。
