Embodiment 1
[0065] refer to Figure 1-Figure 4 As shown, this embodiment provides an aircraft pitot tube extension tube, including:
[0066] The first extension tube 2, the second extension tube 5 and the first clamping member 7;
[0067] The rear end of the first extension tube 2 is provided with a folding portion 21, and the front end of the second extension tube 5 is provided with a fixing portion 51. The folding portion 21 and the fixing portion 51 are detachably connected. When the extension tube 5 is rotated to form an included angle state, the first extension tube 2 and the second extension tube 5 are fixedly connected by the first clamping member 7 .
[0068] In this embodiment, the folding portion 21 and the fixing portion 51 are hollow columnar structures, and are respectively fixed on the outer circumferences of the ends of the first extension pipe 2 and the second extension pipe 5;
[0069] The upper portion of the side surface of the folding portion 21 facing the fixing por...

The invention provides an airspeed tube extension tube applied to an unmanned aerial vehicle, which belongs to the technical field of airspeed tubes and comprises a first extension tube, a second extension tube and a first clamping piece, a folding part is arranged at the end part of the rear end of the first extension tube, a fixing part is arranged at the end part of the front end of the second extension tube, the folding part is detachably connected with the fixing part, and when the first extension tube rotates relative to the second extension tube to form an included angle, the first extension tube and the second extension tube are fixedly connected through a first clamping piece. The technical scheme has the beneficial effects that compared with an existing non-folding airspeed tube extension tube structure, the heading size of the unmanned aerial vehicle in the transportation state is greatly reduced, and the extension tube structure is suitable for occasions where the heading size is limited in the transportation process of the unmanned aerial vehicle, especially for large unmanned aerial vehicles; the extension pipe can reduce the length of a transportation assembly, improve the transportation efficiency and reduce the transportation cost.
Description
technical field [0001] The invention belongs to the technical field of pitot tubes, and more particularly relates to a pitot tube extension tube applied to unmanned aerial vehicles. Background technique [0002] The pitot tube on the UAV is an important atmospheric data sensor, which is used to accurately detect the static pressure and total pressure of the atmospheric environment around the UAV under flight conditions. These measured pressure data can be converted into flight parameter information such as the UAV's flight Mach number, air pressure altitude, and lift speed, and displayed for output. [0003] However, with the development of unmanned aerial vehicles, the length of the pitot tube on the head of the unmanned aerial vehicle has caused great trouble to transportation, especially in the carrier-based scene with demanding space requirements, shortening the length of the entire unmanned aerial vehicle has the advantages of Significance. Conventional pitot extensio...
