Example Embodiment

[0020] Example 1

[0021] An emergency landing device for agricultural plant protection drones, including multiple airbags 2, multiple collision sensors 5, collision sensors 3, airbag computers 4 and automatic inflator 7; the number of airbags 2 is greater than or equal to 5 Are evenly installed on the bottom of the plant protection drone shell 1 and the outer surface around it; the multiple collision sensors 5, collision sensors 3, airbag computer 4 and automatic inflator 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, and they are evenly installed on the bottom of the plant protection drone housing 1 and the inner walls around them. The collision sensors 5 are connected to the collision sensors 3 through a signal transmission line 6. The airbag computer 4 is connected to the collision sensor 3 and the automatic inflator 7 respectively. The collision sensor is used to sense the impa...

Example Embodiment

[0026] Example 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 Example 1 is that the automatic inflation device 7 is composed of multiple gas branch pipes 10 and electric explosive pipes 12. One end of the multiple gas branch pipes 10 is connected to the electric squib 12, and the other end is connected to the multiple airbags 2; the electric squib 12 is controlled by the airbag computer 4, and contains an electric ignition medium, Gunpowder powder and gas generating agent.

[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, and once the collision sensor detects any direction of the agricultural plant protection drone In the eve...

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 ...
