The invention discloses a photoelectric ball protection device for a reconnaissance type unmanned aerial vehicle. A photoelectric ball (2) is arranged at the belly of the unmanned aerial vehicle in front of a nose landing gear (1); a supporting mechanism (3) of the nose landing gear (1) is connected with a front fork (4) through a pair of double-lug bolts, and the front fork (4) is connected with a front wheel (5); the double-lug bolts are respectively a strong bolt (6) and a weak bolt (7); under the condition that the airplane heavily lands or rushes out of a runway, the weak bolt (7) is cut off, and the lower part of the front fork (4) can be stopped after rotating around the strong bolt (6) by a preset angle; after locking, the total descending height of the nose landing gear (1) is smaller than the sum of the total compression distance of a buffer of the nose landing gear (1) and the safe distance between the photoelectric ball (2) and the ground. The survival probability of the photoelectric ball in airplane heavy landing and runway rushing-out accidents can be improved.
本发明公开了一种侦察型无人机光电球保护装置,前起落架(1)前方的无人机机腹处设有光电球(2);前起落架(1)的支撑机构(3)经一对双耳螺栓与前叉(4)连接,前叉(4)与前轮(5)连接;双耳螺栓分别为强螺栓(6)和弱螺栓(7);在飞机重着陆或是冲出跑道的情况下,弱螺栓(7)被剪断,前叉(4)下部绕强螺栓(6)旋转预设角度后能被止动;止动后,前起落架(1)总下降高度小于前起落架(1)缓冲器全压缩距离与光电球(2)离地安全距离之和。本发明能提高光电球在飞机重着陆和冲出跑道事故中的幸存概率。
