The recoverable hatch cover structure of the fixed-wing unmanned aerial vehicle comprises a hatch cover, the installation end of the hatch cover is rotationally installed on a parachute bay, and the locking end of the hatch cover is provided with a locking rod; the blocking piece is arranged on the inner side wall of the parachute bay in an up-down sliding mode, and when the blocking piece is located at the blocking working position, the opening of the parachute bay is prevented from being sealed by the bay cover; one end of the stay wire is connected with the blocking piece, the other end of the stay wire is connected with the main bearing piece, and the main bearing piece drives the stay wire to move when moving upwards, so that the blocking piece moves upwards to the blocking working position and is kept at the blocking working position; the locking and unlocking mechanism is arranged in the parachute bay and used for being matched with the lock rod to lock or unlock the lock rod. The stopping piece and the main bearing piece are connected through the pull wire, after the parachute is thrown out, the main bearing piece can be driven to move upwards, the main bearing piece can move upwards to drive the stopping piece to move upwards to the stopping working position and keep at the stopping working position, and the situation that the opened cabin cover rotates backwards to close the opening of the parachute cabin is effectively prevented.
本申请公开了一种固定翼无人机的可回收舱盖结构,包括:舱盖,舱盖的安装端转动安装在伞舱上,舱盖的锁定端具有锁杆;阻挡件,上下滑动设置在伞舱的内侧壁上,阻挡件在阻挡工作位时,阻止舱盖封闭伞舱的开口;拉线,一端与阻挡件连接,另一端与主承载件连接,主承载件上移时带动拉线移动,使阻挡件上移至阻挡工作位并保持在阻挡工作位;锁定解锁机构,设置在伞舱内,用于与锁杆配合,锁定或解锁锁杆。本申请通过拉线连接阻挡件和主承载件,当降落伞抛出后,能够带动主承载件上移,主承载件上移能够带动阻挡件上移至阻挡工作位并保持在阻挡工作位,有效防止打开后的舱盖往回转动封闭伞舱开口。
