The invention relates to an unmanned aerial vehicle overwater anti-rollover system. The system comprises the unmanned aerial vehicle and a safety air bag, undercarriages are arranged at the bottom of the unmanned aerial vehicle, the undercarriages are symmetrically arranged along the center line of the unmanned aerial vehicle, the safety air bag is arranged on the belly of the unmanned aerial vehicle and connected with the undercarriages, the safety air bag is used for enabling the unmanned aerial vehicle to float on the water surface, and an anti-turning part and a pushing source are arranged in each undercarriage; the pushing source pushes the anti-turning part to slide out of the undercarriage, the anti-turning part comprises an umbrella rod and an anti-turning umbrella, the umbrella rod and the anti-turning umbrella are arranged in a matched mode, the umbrella rod and the anti-turning umbrella are connected in the undercarriage in a sliding mode, the pushing source pushes the umbrella rod, and the umbrella rod drives the anti-turning umbrella to slide out of the undercarriage. The forced rainfall surface and the anti-overturning part are pushed into the undercarriage, namely, the gravity center of the unmanned aerial vehicle is lowered below the water surface, the anti-overturning umbrella has a counter-acting force to keep the unmanned aerial vehicle balanced, so that the unmanned aerial vehicle is protected, the unmanned aerial vehicle does not need to be forced to descend to the water surface, the anti-overturning part is retracted into the undercarriage, loss is minimized, and the system is simple in structure, convenient to operate, low in cost, and facilitates application and popularization.
本发明涉及一种无人机水上防翻系统,包括无人机和安全气囊,无人机底部设置有起落架,起落架沿无人机中线对称设置,安全气囊设置在无人机的机腹且与起落架连接,安全气囊用于无人机漂浮在水面,起落架内部设有防翻部和推动源,推动源推动防翻部滑出起落架,其中防翻部包括伞杆和防翻伞,伞杆与防翻伞配合设置,起落架内滑动连接伞杆和防翻伞,推动源推动伞杆,伞杆带动防翻伞滑出起落架内。本发明被迫降水面,防翻部推出起落架中,相当于将无人机的重心降到了水面以下,防翻伞有一反作用力使得无人机保持平衡,从而保护了无人机,无需迫降水面,防翻部收入起落架中,使得损失最小化,此系统结构简单,操作方便,成本较低,便于应用和推广。
