Description

Unmanned aerial vehicle is put in rescue of putting out a fire Technical Field The invention relates to the technical field of fire-extinguishing rescue equipment, in particular to a fire-extinguishing rescue throwing unmanned aerial vehicle. Background With the development of unmanned aerial vehicle technology, the unmanned aerial vehicle has unique application value in the difficult-to-access scenes such as fire extinguishment, particularly high-rise buildings, early forest fires, dangerous chemical accidents and the like, and the existing unmanned aerial vehicle mainly comprises two types, namely an unmanned aerial vehicle carrying a liquid extinguishing agent storage tank and a spraying system, and a throwing unmanned aerial vehicle carrying a fire extinguishing bomb. The first type of liquid sprays unmanned aerial vehicle, its shower nozzle is mostly fixed or can only carry out simple horizontal reciprocating swing, and this kind of flame area that sprays the mode and covers is limited, especially when facing three-dimensional scene of a fire or need quick pressure fire, fixed spraying orbit is difficult to form effectual three-dimensional cover, and fire extinguishing efficiency remains to promote, and simultaneously, single spraying mode has also limited its adaptability to different forms of fire sources. Unmanned aerial vehicle is put in to second class fire extinguishing bomb, adopts simple release mechanism generally, throws the fire extinguishing bomb from the sky directly down, and this kind of mode precision is lower, and fire extinguishing bomb landing point dispersion is difficult to deliver to the fire source core area, probably causes fire extinguishing agent extravagant or secondary disaster risk, and in addition, single-function unmanned aerial vehicle is facing complicated changeable condition of a fire, and task adaptability is not enough, often needs unmanned aerial vehicle collaborative operation of different grade type, has increased command coordination's degree of difficulty and cost. Therefore, a multifunctional fire-fighting unmanned aerial vehicle integrating large-scale, three-dimensional spraying capability and accurate and controllable throwing capability is needed, so as to overcome the defects of single fire-fighting mode, uneven coverage and insufficient task adaptability in the prior art. Disclosure of Invention First, the technical problem to be solved Aiming at the defects of the prior art, the invention provides a fire-extinguishing rescue throwing type unmanned aerial vehicle, which solves the problems of single fire-extinguishing mode, uneven coverage and insufficient task adaptability in the prior art. (II) technical scheme The fire-extinguishing rescue throwing type unmanned aerial vehicle comprises an unmanned aerial vehicle body, a bracket fixedly arranged at the bottom of the unmanned aerial vehicle body, a spraying swing mechanism arranged on the bracket, a driving assembly for driving the spraying swing mechanism to act, and a fire-extinguishing bullet throwing assembly arranged at the bottom of the bracket. The spraying swing mechanism comprises a rotating shaft vertically installed in the bracket in a rotating way, a sliding rail axially and fixedly arranged on the side wall of the rotating shaft along the rotating shaft, a sliding block arranged on the sliding rail in a sliding way, a swing frame fixedly arranged on the side wall of the sliding block, and a spray head fixedly installed at one end of the swing frame far away from the rotating shaft; an arc-shaped plate is fixedly arranged in the bracket, a wave groove is formed in the arc-shaped plate, and the swing frame penetrates through the wave groove and can slide along the wave groove; The driving assembly drives the rotating shaft to reciprocate to drive the swinging frame and the spray head to generate left-right reciprocating swinging motion, and meanwhile, the swinging frame is constrained by the contour of the wave groove, so that the sliding block drives the swinging frame to synchronously slide up and down along the sliding rail, and the spraying direction of the spray head is enabled to periodically swing to expand the coverage range; the fire extinguishing bomb throwing component is used for throwing fire extinguishing bomb to a fire scene at fixed points. According to the fire-extinguishing rescue throwing type unmanned aerial vehicle, when a fire-extinguishing task is executed, the unmanned aerial vehicle flies to the upper part of a fire scene, a spraying system is started, a driving assembly drives a rotating shaft to do reciprocating rotation motion in a certain angle, the rotating shaft drives a sliding rail, a sliding block and a swinging frame on the rotating shaft to swing left and right integrally, meanwhile, the swinging frame penetrates through an arc-shaped plate wave groove fixed on a support, the movement of the swinging frame is restrained by the wave groove, when the swingin
