Anti-falling and propeller protection device for unmanned aerial vehicle

Abstract

The invention discloses an anti-falling and propeller protection device for an unmanned aerial vehicle. The device comprises a rack, a power box and a driving system, the bottom of the power box is fixedly connected with a camera; a base is fixedly connected to the bottom of the rack, rotating motors are fixedly connected to the two sides of the rack, propellers are fixedly connected to output shafts of the two rotating motors through couplers, an umbrella box is fixedly connected to the top of the power box, and the bottom of the umbrella box penetrates through the power box and extends intothe power box. The invention discloses an anti-falling and propeller protection device for an unmanned aerial vehicle. An umbrella ejecting device is arranged in an umbrella box; according to the parachute ejecting device, the parachute ejecting device can be opened through the cooperation relation of the moving rod, the first sliding block and the second sliding block and the cooperation of the supporting rod and the sliding plate, the unmanned aerial vehicle lands slowly, the unmanned aerial vehicle can be effectively protected. Meanwhile, propellers are prevented from making contact with the ground and being damaged, and therefore the safety of the unmanned aerial vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of UAV protection, in particular to an anti-drop and propeller protection device for UAVs. Background technique [0002] Unmanned aircraft, referred to as UAV, is an unmanned aircraft controlled by radio remote control equipment and self-contained program control device, and is rapidly developing equipment. The advantages of low requirements, UAVs can realize real-time image transmission, detection of high-risk areas and other functions by carrying multiple types of sensors. Communication, meteorology, agriculture, ocean, exploration, photography, disaster prevention and mitigation, crop yield estimation, anti-drug and anti-smuggling, border patrol, public security and anti-terrorism and other fields are widely used, especially now that aerial photography is prevalent. [0003] Existing drones may encounter emergencies such as low battery power or accidental collisions during work. In this situation, it is ...
