Stabilizing device based on spraying pipe spraying unmanned aerial vehicle

Abstract

The invention discloses a stabilizing device for an unmanned aerial vehicle based on spraying of a spraying pipe, and belongs to the field of unmanned flight, the stabilizing device comprises a base, the base is provided with the spraying pipe, the bottom surface of the base is fixedly provided with a thrust device, and the thrust direction of the thrust device is opposite to the spraying direction of the spraying pipe; a guide device capable of changing the water flow direction is elastically and movably arranged at the spraying end of the spraying pipe; according to the stabilizing device for the unmanned aerial vehicle based on spraying pipe spraying, by arranging the reverse thrust rotor wings, when the aircraft conducts spraying fire extinguishing, reaction is balanced, the fuselage can reach balance, the flow speed of sprayed water flow is collected and fed back to the reverse thrust rotor wings, the reverse thrust can be adjusted in real time, and the stability of the unmanned aerial vehicle is improved. The aircraft can be balanced in real time, and the influence of external force is reduced.

Description

technical field [0001] The invention belongs to the field of unmanned flight, and specifically relates to a stabilizing device for a nozzle-based unmanned aerial vehicle. Background technique [0002] With the development of UAV technology, there are now UAVs in various industries to replace manual work. For example, in terms of fire fighting, UAVs have unique advantages. It can enter different heights, eliminating the need for traditional The cumbersome procedures of erecting the ladder can not only save costs, but also improve the speed of fire extinguishing, which can protect the safety of firefighters. [0003] Generally, when a UAV enters a high-rise fire, it usually carries a fire hose into the air, and then sprays water on the fire. During the process of spraying water, the reaction force generated by the water pipe will affect the UAV itself. Balance, although some drones can adjust their posture according to their own feedback, but when the thrust of the water pipe...

AI Technical Summary

Problems solved by technology

[0005] When the aircraft enters the fire extinguishing field, due to the existence of a large amount of thick smoke, the vision will be affected. At this time, it is very difficult to control the aircraft. If the rotor collides with the wall, it is easy to cause a crash. Therefore, when working in a complex environment, it is necessary to protect the aircraft
