Fire protection unmanned aerial vehicle

Abstract

The invention relates to a fire-fighting unmanned aerial vehicle, which includes a fuselage and a steering gear arranged at the bottom of the fuselage, an inverted U-shaped fixing frame arranged under the steering gear, a support rod arranged on the top plate of the fixing frame, and a The buffer rod at the lower end of the support rod and the fire extinguishing bomb launch tube fixedly connected with the buffer rod; two installation waist-shaped holes are arranged on the top plate, and a buffer waist-shaped hole is respectively provided on the two side plates of the fixing frame; the support rod is connected with the The connection of the waist hole is installed; the buffer rod is parallel to the top plate and penetrates in the two buffer waist holes. The present invention can buffer the back thrust generated by the fire extinguishing bomb launching tube when the fire extinguishing bomb is launched by sliding the buffer rod within a certain range in the buffer waist hole, so as to prevent the steering gear and the parts of the UAV from being damaged by the back thrust and prolong the The service life of the UAV and its components. The buffer structure of the invention is simple and 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
