Embodiment Construction
[0035] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings. Wherein, the same parts adopt the same reference numerals.
[0036]As described in the background technology, this application proposes an alternative structure for the deficiencies of the support rods disclosed in the prior art Chinese patent application 201711089234.8, which provides tension through flexible cable-stayed steel cables, and ensures reliable disassembly and assembly. Tension members are provided to replace the existing hard support structure which further reduces the weight of the structure.
[0037] Specifically, the cable-stayed cables for oil-powered UAVs of this application are further improvements proposed on the basis of the support rods of 201711089234.8. This application cites this prior art in its entirety,...

The invention discloses a stayed steel cable for an oil-driven unmanned aerial vehicle. The stayed steel cable is connected between an airframe and a cantilever of the unmanned aerial vehicle, whereinthe middle of the stayed steel cable is provided with a rapid dismounting structure; the rapid dismounting structure is composed of a bolt connecting piece, a snap joint sleeve, a snap frame connecting piece, a limiting sleeve and a flange connecting piece; one end of the snap frame connecting piece is provided with a threaded hole connected with a threaded rod of the bolt connecting piece, and the other end of the snap frame connecting piece is provided with an unthreaded hole for snapping a flange of the flange connecting piece; the snap frame connecting piece is clamped between the snap joint sleeve and the limiting sleeve; and the snap joint sleeve and the limiting sleeve are connected together by using a screw thread. The stayed steel cable for the oil-driven unmanned aerial vehicle,disclosed by the application, is simple and reliable in structure, convenient to dismount and mount, beneficial to time conservation during dismounting / mounting operation and capable of reducing thelabor intensity and replacing an existing hard supporting structure to further reduce the structural weight.
Description
technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a multi-rotor oil-powered unmanned aerial vehicle, and in particular to a cable-stayed cable and a disassembly method for the oil-driven unmanned aerial vehicle. Background technique [0002] Multi-rotor oil-powered UAV is an unmanned aerial vehicle with multiple cantilevers. It has a simple structure, low noise, flexible maneuverability, fast response, and low operation requirements. It is widely used in agricultural plant protection, forest fire monitoring, Aerial photography, land surveying, post-disaster damage assessment and other tasks. [0003] Existing multi-rotor drones are usually electric drones. The structure of the multi-rotor electric UAV is simple and easy to manufacture, the motor is light in weight, the rotation is stable, and the power system is easy to standardize. Therefore, the whole machine is relatively easy to control, and the flight nois...
