▎ 摘　　要

NOVELTY - The device has main portion (1) which is provided with a control plate (4) and ejection column (2). The ejection column is located at center of control plate. A parachute is connected to upper end of ejector. An attitude sensor (18) is mounted on upper end of control plate. The main portion is surrounded by mounting slots and recesses. A graphene sensor is mounted on inner end of mounting groove. An intelligent denature material (3) is arranged around the main portion. The intelligent denature material is fixedly connected with connecting column between inner bottom end of groove. The outer end of connecting column is fixedly connected with elastic plate. The inner end of elastic plate is drilled with water outlet holes. The upper spikes are fixedly connected below elastic plate. The grooves are respectively placed in grooves on left and right sides of connecting column. The water bladder is located below upper spike. A puncture device is arranged below the water bladder. USE - Automatic anti-collision protection device used in unmanned aerial vehicle. Uses but are not limited to aerial photography field, agriculture field, plant protection field, micro-self-timer, express transportation field, disaster relief, observation of wildlife, surveillance of infectious diseases, mapping field, news report, power inspection field, disaster relief, and film and TV shooting field. ADVANTAGE - The graphene sensor is installed at inner end of the installation slot, and the intelligent denature material is arranged around the main portion of the unmanned aerial vehicle so as to protect the unmanned aerial vehicle effect by changing the shape of the intelligent denature material after the impact, and realize under certain circumstances. The unmanned aerial vehicle is balanced, when the unmanned aerial vehicle is not in control, so that the unmanned aerial vehicle is protected by parachute to enable the unmanned aerial vehicle to land safely. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of the automatic anti-collision protection device.
