Detachable ring-pillar type hollow unmanned aerial vehicle and operation method thereof

Abstract

The invention discloses a detachable ring-pillar type hollow unmanned aerial vehicle and an operation method thereof. The unmanned aerial vehicle comprises a rack, a power and control mechanism and a central fastening device, wherein the rack comprises a fixing disc and at least two engine arms, the fixing disc has a double-layer, detachable and hollow structure, the starting end of each engine arm is fixed on the fixing disc and is symmetrically distributed along a detachable line on the fixing disc; the power and control mechanism comprises upper paddle rotor wings, upper paddle motors, upper paddle electronic speed regulators and flight control modules; the upper paddle rotor wings are arranged at the tail ends of the engine arms and are driven by the upper paddle motors, the downward wind power is generated by rotation, the flight control modules are used for controlling the rotation of the upper paddle motors through the upper paddle electronic speed regulators; the central fastening device is used for fastening an unmanned aerial vehicle on an operation trunk when the upper paddle rotor ring stops rotating. According to the detachable ring-pillar type hollow unmanned aerial vehicle, the fixing disc is sleeved on the outer diameter of the operation trunk to operate, and when the appointed height is reached, the fastening device is used for fastening the unmanned aerial vehicle on the operation trunk; and the detachable ring-pillar type hollow unmanned aerial vehicle has the advantage of energy saving.

Description

technical field [0001] The invention relates to the field of forestry machinery equipment research, in particular to a detachable ring-column hollow unmanned aerial vehicle and an operating method thereof. Background technique [0002] Trees with tall and straight trunks are ubiquitous in our country. Taking the common king coconut in tropical areas as an example, its tree height can reach 20 meters and its trunk is straight. It is a world-renowned tropical tree species, usually used as street trees or group planted as green spaces landscape tree. Because the canopy of leaves is too high, it is impossible to use ground machinery or manual spraying to prevent and control pests and diseases. If small drones are used for aerial spraying operations, there will be a problem that the density of trees will be high, which will limit the flying space of aircraft. At the same time, it is not suitable to use Large aircraft, so the drug loading capacity is small. In addition, the airc...

AI Technical Summary

Problems solved by technology

Because the canopy of leaves is too high, it is impossible to use ground machinery or manual spraying to prevent and control pests and diseases. If small drones are used for aerial spraying operations, there will be a problem that the density of trees will be high, which will limit the flying space of aircraft. At the same time, it is not suitable to use Large aircraft, so the drug loading capacity is small

In addition, the plane generally flies in the upper part of the canopy, so the lower part of the leaf surface cannot be effectively sprayed.

[0003] At present, in the field of agriculture, UAVs used in various operations generally have the characteristics of unlimited movement space, but when they hover in the air, the rotor must rotate to provide a lift that overcomes gravity, thereby ensuring the hovering of the UAV in the air. or flight attitude, which produces a lot of energy consumption and will inevitably reduce the payload

In addition, an expensive attitude control system must be used to ensure the balance of the body during operation. At the same time, the control method of variable operation must be satisfied. The control method is complicated and the effect is not good.
