The invention discloses an unmanned helicopter forced landing emergency parachute, and relates to the technical field of unmanned helicopters. The parachute comprises a machine body, the bottom of the machine body is fixedly connected with a rack, one side of the helicopter body is fixedly connected with a tail rotor device, and the top of the helicopter body is fixedly connected with a main rotor device. Through an arranged auxiliary fixing device, a parachute device is conveniently fixed and disassembled, when a driving motor rotates in the opposite direction, a movable clamping block is driven to be gradually separated from one side of a clamping groove plate, a connecting block and a T-shaped plate move at the same time, and when the T-shaped plate moves, an upper clamping wheel and a lower clamping wheel are driven to move at the same time; and connecting plates move simultaneously and drive an upper clamping groove to be clamped with an upper clamping wheel, the T-shaped plate, the upper clamping wheel and the lower clamping wheel incline simultaneously, the connecting plates continue to move to drive a clamping wheel and the lower clamping wheel to move simultaneously, and the lower clamping wheel is gradually separated from the inner wall of a lower clamping groove plate. Therefore, disassembly is convenient, and the parachute device can be replaced in time when damaged, and normal use of the parachute device during emergency landing of the helicopter is ensured.

    本发明公开了一种无人直升机迫降紧急降落伞,涉及无人直升机技术领域,包括机体,所述机体的底部固定连接有机架,所述机体的一侧固定连接有尾桨装置,所述机体的顶部固定连接有主旋翼装置。通过设置的辅助固定装置,方便固定和拆卸降落伞装置,驱动电机反方向转动时带动移动卡接块与卡接槽板的一侧逐渐分离,连接块和T型板同时移动,T型板移动时带动上卡接轮和下卡接轮同时移动,连接板同时移动并带动上卡槽与上卡接轮卡接,T型板、上卡接轮和下卡接轮同时倾斜,连接板继续移动带动卡接轮和下卡接轮同时移动,下卡接轮与下卡槽板的内壁逐渐分离,方便拆卸,降落伞装置在损坏时能够及时更换,保证了降落伞装置在直升机紧急降落时的正常使用。
