Fire-fighting unmanned aerial vehicle

Abstract

The invention relates to a fire-fighting unmanned aerial vehicle. The fire-fighting unmanned aerial vehicle comprises a vehicle body, a steering engine, an inverted U-shaped fixing frame, support rods, a buffer rod and a fire extinguishing bomb launching barrel, wherein the steering engine is arranged at the bottom of the vehicle body; the inverted U-shaped fixing frame is arranged below the steering engine; the support rods are arranged on a top plate of the fixing frame; the buffer rod is fixed to the lower ends of the support rods; the fire extinguishing bomb launching barrel is fixedly connected with the buffer rod; the top plate is provided with two mounting waist-shaped holes; two side plates of the fixing frame are provided with a buffering waist-shaped hole respectively; the support rods are connected with the mounting waist-shaped holes through bolts; the buffer rod is parallel to the top plate, and is inserted into the two buffering waist-type holes. When the buffer rod slides in the buffering waist-shaped holes in a certain range, back thrust force generated by the fire extinguishing bomb launching barrel during launching of a fire extinguishing bomb can be buffered, sothat the steering engine and unmanned aerial vehicle components are prevented from being damaged by the back thrust force, and the service lives of the unmanned aerial vehicle and the components thereof are prolonged. The fire-fighting unmanned aerial vehicle is simple in buffering structure, and is convenient to manufacture and use.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a fire-fighting unmanned aerial vehicle. Background technique [0002] With the development of the world economy, there are more and more high-rise and super high-rise buildings in cities. Once a fire breaks out in a high-rise building of tens of meters or even hundreds of meters, it will face the problem of fire protection. UAV technology is a relatively mature technology now, with flexible operation and fast speed, and can reach designated places without being restricted by geographical environment. Now there is a practice of using UAVs for fire rescue. UAVs directly throw fire extinguishing materials, such as launching fire extinguishing bombs. The fire extinguishing bombs fired sometimes need to penetrate the glass, so that the firing of the fire extinguishing bombs will cause back thrust to the drone and the fire extinguishing bomb launcher and ...

AI Technical Summary

Problems solved by technology

The fire extinguishing bombs fired sometimes need to penetrate the glass, so that the launching of the fire extinguishing bombs will cause back thrust to the drone and the fire extinguishing bomb launcher and other mechanisms, and cause different degrees of wear and damage to these mechanisms, and affect the accuracy of the launch. Reduced drone lifespan
