The invention particularly relates to a helicopter auxiliary landing visual system in a sand blowing environment. The system is composed of a helicopter main rotor, a rotor hub, a main rotor speed reducer, a camera protection cover, a pan-tilt camera, a camera lifting rod, a lifting rod fixing bolt, a motor, a speed reducer, a deep groove ball bearing and a helicopter body. According to the design, the pan-tilt camera and the lifting device are installed in the propeller hub of the main rotor, when the ground and the surrounding environment need to be monitored, the motor speed reducer drives the lead screw to rotate, the lifting rod drives the pan-tilt camera to extend to the position above the rotor by a certain distance, and at the moment, the pan-tilt camera can monitor wider and more comprehensive environment information. According to the system, when the helicopter flies, hovers or lands close to the ground in a dry environment containing a large number of dispersed phase particles such as sand, adverse effects caused by the particles such as the sand can be effectively reduced, and the flight safety is improved.
本发明具体涉及一种扬沙环境的直升机辅助降落视觉系统。该系统由直升机主旋翼、旋翼桨毂、主旋翼减速器、相机保护罩、云台相机、相机升降杆、升降杆固定螺栓、电机、减速器、深沟球轴承、直升机机身构成。该设计通过将云台相机和升降装置安装在主旋翼桨毂内,当需要对地面及周围环境进行监控时,电机减速器带动丝杆旋转,使得升降杆带动云台相机伸出至旋翼上方一定距离处,此时云台相机将监控到更加广阔全面的环境信息。该系统有利于直升机在含有大量沙尘等离散相颗粒的干燥环境中贴地飞行、悬停或降落时,能有效减少沙尘等颗粒带来的不利影响,提升飞行安全性。
