Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle equipment, in particular to a quick-detachable pitot tube device and a unmanned aerial vehicle. Background Art

[0002] At present, industrial drones are being used more and more widely in surveying and mapping, exploration, disaster monitoring, meteorological detection, border patrol monitoring, emergency rescue, emergency communications, logistics, and military use.

[0003] As we all know, the airspeed system is crucial to the aircraft and plays an extremely important role in the safe take-off and landing process. The airspeed system includes the pitot assembly and the airspeed meter. The pitot assembly is used to detect the total pressure and static pressure of the airflow, and converts the measured pressure into digital information data through the airspeed meter, and then transmits it to the flight control computer. The pitot assembly and the airspeed meter are one of the main components of the aircraft, and their performance is directly related to the safety of the aircraft.

[0004] The airspeed system in the prior art is an extremely important measuring tool on an aircraft. It is generally installed in front of the nose, the vertical tail or the wing tip. However, the existing pitot tube structure has many parts, is complex to install, has limitations in use, and cannot be used for all types of aircraft. At the same time, after the pitot tube is installed, its structure protrudes more from the surface of the drone body, resulting in large aerodynamic resistance, which affects the flight of the drone. In view of this, we propose a quick-detachable pitot tube device and a drone. Utility Model Content

[0010] Preferably, the outer wall of the pitot tube tail seat is provided with threads and bonded to the pitot tube body by resin. According to this preference, after the pitot tube tail seat is docked with the dynamic pressure head, the pitot tube body is located between the two while ensuring sufficient length.

[0011] Preferably, the pitot tube body is bonded to the dynamic pressure head by resin, and the pitot tube hose is connected to the dynamic pressure head and the pitot tube tail seat respectively.
