Description

Unmanned aerial vehicle puts out a fire with automatic function of changing bullet The invention discloses a divisional application of application number CN202311056551.5, which is named as a fire-extinguishing unmanned aerial vehicle with an automatic bullet changing function, and the application date of the original application is 2023, 8 and 21. Technical Field The invention belongs to the technical field of fire extinguishing bomb launching devices, and particularly relates to a fire extinguishing unmanned aerial vehicle with an automatic bomb changing function. Background Unmanned aerial vehicles are used as a novel industrial technology and gradually come into wide application in various emergency rescue occasions, and various institutions in China successfully detect and monitor fire fields by using the unmanned aerial vehicles and throw rescue materials, so that the effect is very obvious. The fire extinguishing unmanned aerial vehicle has the characteristics of strong maneuverability, high flexibility and the like, can reach a fire scene in the first time, and particularly can replace part of manpower action by using the unmanned aerial vehicle under high-risk situations such as high-place fire extinguishment or ultra-high voltage intensive transmission channel fire extinguishment, so that the working condition of firefighters at high places can be reduced, and the importance of the unmanned aerial vehicle is self-evident. Currently, fire fighting unmanned aerial vehicles are generally classified into a bullet type and a shooting type. The bullet-throwing type fire-extinguishing unmanned aerial vehicle refers to a high-altitude multi-emission type fire-extinguishing unmanned aerial vehicle named as 'high-altitude multi-emission type fire-extinguishing unmanned aerial vehicle' with a Chinese patent bulletin number 'CN 215098277U' and a fire rescue unmanned aerial vehicle named as 'fire rescue unmanned aerial vehicle' with a Chinese patent bulletin number 'CN 112386832A', a bullet storage box is adopted, fire-extinguishing bullets are stacked in the bullet storage box, and related fire-extinguishing work is carried out in a mode of projecting single or multiple fire-extinguishing bullets at a time when the bullet-throwing type fire-extinguishing unmanned aerial vehicle is used. The bullet-throwing type fire-extinguishing unmanned aerial vehicle has the advantages that firstly, fire-extinguishing bullets in a bullet storage box roll easily, particularly, the movable space of the remaining fire-extinguishing bullets in the bullet storage box gradually becomes larger along with the increase of the number of the bullets, the shaking condition of the fire-extinguishing bullets is more obvious, the stability and the safety are not high, and secondly, the fire-extinguishing unmanned aerial vehicle completely depends on gravity to throw the bullets when in use, so that accurate fire extinguishment is not facilitated. The shooting type fire extinguishing unmanned aerial vehicle has the advantages of stable fixation of fire extinguishing bomb and high fire extinguishing precision, so that the fire extinguishing unmanned aerial vehicle is widely used. The shooting type fire extinguishing unmanned aerial vehicle is divided into a single-shot type fire extinguishing unmanned aerial vehicle and a multiple-shot type fire extinguishing unmanned aerial vehicle, and the use occasions of the single-shot type unmanned aerial vehicle are more and more limited because the filling time of the loaded fire extinguishing bomb is longer and the replacement of the fire extinguishing bomb needs to be carried out by returning to the ground. The name of the multi-shot unmanned aerial vehicle refers to a Chinese patent publication number CN106581906A, namely a high-rise building fire extinguishing device based on the unmanned aerial vehicle or a Chinese patent publication number CN210284612U, namely a high-altitude multi-emission fire extinguishing unmanned aerial vehicle, and the fire extinguishing effect is achieved by mounting a vertical magazine or a rotating wheel magazine on the abdomen of the unmanned aerial vehicle. However, on the one hand, the rotating wheel magazine has the problem that the fire extinguishing bomb itself has a large weight, and as the fire extinguishing bomb is sequentially ejected and the rotating wheel magazine gradually rotates, one side of the empty bomb becomes lighter and lighter, so that the weights of the two sides of the rotating wheel magazine are gradually unbalanced, and further, the operability and the use safety are sharply reduced. On the other hand, although the vertical magazine can solve the unbalance problem, in order to be matched with a launching device, the rotating wheel magazine and the vertical magazine are always placed in the middle, so that the whole height of the unmanned aerial vehicle can be increased, and the unmanned aerial vehicle is very unfavorable for transportation.
