Embodiment 1

[0021] An agricultural plant protection unmanned aerial vehicle fault forced landing device, comprising a plurality of safety airbags 2, a plurality of collision sensors 5, a collision sensor 3, a safety airbag computer 4 and an automatic inflation device 7; the number of the safety airbags 2 is greater than or equal to 5 One, evenly installed on the bottom of the plant protection drone shell 1 and the outer surface around it; the plurality of collision sensors 5, collision sensors 3, airbag computer 4 and automatic inflation device 6 are installed on the plant protection drone shell 1 internal;

[0022] Wherein, the number of collision sensors 5 is greater than or equal to 5, which are evenly installed on the bottom of the plant protection drone casing 1 and the inner wall surface around it, and the collision sensors 5 are connected with the collision sensor 3 through a signal transmission line 6. The airbag computer 4 is respectively connected with the collision sensor 3 and...

Embodiment 2

[0027] The difference between the emergency landing device for agricultural plant protection drones described in this embodiment and the emergency landing device for agricultural plant protection drones described in Embodiment 1 is that the automatic inflation device 7 is composed of a plurality of gas branch pipes 10 and electric squibs 12, One end of the plurality of gas branch pipes 10 is connected with the electric detonator 12, and the other end is connected with the plurality of safety airbags 2; the electric detonator 12 is controlled by the airbag computer 4, and contains electric ignition medium, Gunpowder powder and gas generant.

[0028] The working principle of the emergency landing device for agricultural plant protection drones described in this embodiment is: when the agricultural plant protection drone is in a safe state, the airbag is in a contracted state, once the collision sensor senses any direction of the agricultural plant protection drone When a collisi...

Abstract

The invention discloses an agricultural crop protection unmanned aerial vehicle fault forced landing device. The agricultural crop protection unmanned aerial vehicle fault forced landing device comprises a plurality of safety airbags, a plurality of collision inductors, a collision sensor, a safety airbag computer and an automatic air charging device; the safety airbags are installed on the external surface of an unmanned aerial vehicle outer casing; the plurality of collision inductors, the collision sensors, the safety airbag computer and the automatic air charging device are installed inside the outer casing; the collision inductors which are installed on the internal wall surface of the unmanned aerial vehicle outer casing are connected with the collision sensor through signal transmission lines; the safety airbag computer is connected with the collision sensor and the automatic air charging device; the automatic air charging device is connected with the plurality of safety airbags. According to the agricultural crop protection unmanned aerial vehicle fault forced landing device, when the unmanned aerial vehicle is collided, the safety airbags can be immediately started to form into soft airbag structures, a protection function is formed, the unmanned aerial is guaranteed not being crashed when falls off after losses balance. The agricultural crop protection unmanned aerial vehicle fault forced landing device has the advantages of being simple in structure, unique in design and convenient to operate and having important practical significance in popularizing the unmanned aerial vehicle and improving the application ranges.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to an emergency landing device for an agricultural plant protection drone. Background technique [0002] Agricultural plant protection drones are agricultural drone systems used to spray pesticides in farmland. When agricultural plant protection drones spray pesticides, they usually fly at ultra-low altitude over the farmland (the flight height is generally 2 meters). There are utility poles, trees, houses, etc. in the farmland. The plant protection drone may collide with these obstacles during operation. Once it hits an obstacle, the drone may crash. The current various drone technologies, whether it is fixed-wing aircraft, helicopters or multi-rotor aircraft, cannot solve the problem of collision and crash. Therefore, farmers have concerns about using plant protection drones, which seriously affects the promotion and application of plant protection drones. Contents of the ...
