[0054] In combination Figures 11-15 The embodiment discloses an auxiliary fire-fighting unmanned plane 1-1 in a cooperative fire-fighting unmanned plane group, and the structure comprises a flight platform 15, a throwing device 12, an electric push rod 16, a water hose conveying device 17 and a fire hose 2.

[0055] The difference from the fire-fighting unmanned plane 1 in the embodiment 1 is that the bottom of the throwing device 12 is connected with the top of the electric push rod 16, the electric push rod 16 is provided with a hanging ring 16-1, a telescopic push rod 16-2 and a square mounting seat 16-3.

[0056] Figure 15 When the flight platform 15 is hovering in the air and does not move, the water hose conveying device 17 at the bottom can be moved up and down by the electric push rod 16, so that the fire hose 2 can move up and down and play a fine adjustment role, thereby better cooperating with the fire-fighting unmanned plane 1 to extinguish the fire.

[0057] In combination Figures 16-23 The embodiment discloses a main structure and a working principle schematic diagram of the water hose conveying device 17, and three views and a perspective view of the water hose conveying device 17 are shown in FIG. 16.

[0058] As shown in FIG. 17 and FIG. 18, the main structure of the water hose conveying device 17 comprises two self-locking reduction motors 18, a main base 19, six driven wheels 20, a side cover plate 21 and two driving wheels 22.

[0059] As shown in FIG. 19 and FIG. 20, the main base 19 of the water hose conveying device 17 is fixed with a side cover plate mounting column 19-1 for fixing the side cover plate 21. The main base 19 is provided with six driven wheel mounting columns 19-2 for mounting the six driven wheels 20. The upper four driven wheel mounting columns 19-2 are sequentially fixed on the main base 19, and the lower middle position is also provided with two driven wheel mounting columns 19-2. One driving wheel mounting hole 19-3 is arranged at each of the lower two side positions in the main base 19, for placing the driving wheel 22. One self-locking reduction motor mounting hole 19-4 is arranged outside each of the lower two side positions, for respectively fixing the two self-locking reduction motors 18. The output shaft of the self-locking reduction motor 18 is directly connected with the rotating shaft of the driving wheel 22, for driving the driving wheel 22 to rotate clockwise or counterclockwise. The main base 19 is further provided with a telescopic push rod mounting plate 19-5 at the upper center position, and the whole water hose conveying device 17 is connected to the electric push rod 16 above by four screws.

[0060] The side cover plate 21 in the water hose conveying device 17 is also provided with four side cover plate mounting holes, one driven wheel mounting hole, two driving wheel mounting holes and one telescopic push rod mounting plate fixing hole, which are all correspondingly mounted with the mounting holes and mounting columns on the main base 19 to form an integral whole.

[0061] The driving wheel 22 in the water hose conveying device 17 is shown in Fig. 21, whose rotating shaft is hollow and has internal splines, which can be directly sleeved on the output shaft of the self-locking speed reducer motor 18 with external splines to form a rigid integral whole. The self-locking speed reducer motor 18 can actively drive the driving wheel 22 to rotate clockwise or counterclockwise, and cooperate with the other six driven wheels 20 to drive a long fire hose 2 to move back and forth.

[0062] The driven wheel 20 in the water hose conveying device 17 is shown in Fig. 22, whose rotating shaft is also hollow and can be diametrically sleeved on the driven wheel mounting column provided on the main base 19, which is used to assist in cooperating with the driving wheel 22 to drive the fire hose 2 to move back and forth. The forced movement of the fire hose 2 plays a fine-tuning role, so that it can better cooperate with the fire extinguishing.

[0063] As shown in Fig. Figure 23 The water hose conveying device 17 in the utility model can move the fire hose 2 back and forth. First, a fire hose 2 is inserted between the upper and lower rows of driven wheels 20 and driving wheels 22. When the fire hose 2 is filled with foam water agent, the friction between the two driving wheels 22, six driven wheels 20 and the surface of the fire hose 2 is used to force the fire hose 2 to move back and forth, thereby adjusting the length of the fire hose between the auxiliary fire unmanned aerial vehicle 1-1 and the fire unmanned aerial vehicle 1.

[0064] When a fire occurs on the roof of a high-rise building 4 and the fire unmanned aerial vehicle and the fire truck cannot be deployed from three sides, only one side can be used to let the fire unmanned aerial vehicle 1 fly over to extinguish the fire, but the fire source on the roof is at a relatively remote location. Only one fire unmanned aerial vehicle 1 is difficult to extinguish the fire on the roof of the high-rise building. When the fire unmanned aerial vehicle 1 drags the fire hose to approach the fire source, the wall on the high-rise building will scratch the fire hose, causing water leakage and making it impossible to extinguish the fire. At this time, multiple auxiliary fire unmanned aerial vehicles 1-1 are needed to cooperate to extinguish the fire over a large span and a long distance. When one of the auxiliary fire unmanned aerial vehicles 1-1 malfunctions and falls, the upper thrower 12 immediately throws the lower fire hose 2 to avoid the risk of the malfunctioning auxiliary fire unmanned aerial vehicle 1-1 being pulled by the fire hose 2 along with the other normally flying fire unmanned aerial vehicles 1 and auxiliary fire unmanned aerial vehicles 1-1.

[0065] A use method of the cooperative fire-fighting unmanned aerial vehicle group of the embodiment is as follows: Figure 1 As shown in the figure, when a fire occurs on the top of a high-rise building 4 and the fire source point on the top is at a relatively remote position, only one fire-fighting unmanned aerial vehicle 1 is difficult to put out the deep fire on the top of the high-rise building. When the fire-fighting unmanned aerial vehicle 1 drags a fire hose 2 close to the fire source, the walls around the high-rise building will scratch the fire hose 2, causing water leakage and failing to put out the fire.

[0066] Therefore, the fire-fighting unmanned aerial vehicle 1 and the auxiliary fire-fighting unmanned aerial vehicle 1-1 are arranged in series and maintain a certain distance, and they jointly carry a long fire hose 2. The fire-fighting unmanned aerial vehicle 1 closest to the fire source can spray foam liquid to directly suppress the fire source. The long fire hose 2 passes through the water hose conveying devices 17 of the other three auxiliary fire-fighting unmanned aerial vehicles 1-1 in turn. The water hose conveying devices 17 allow the fire hose 2 to move back and forth, and cooperate with the first fire-fighting unmanned aerial vehicle 1 in front to approach the fire source. A fire truck 3 has the functions of providing power supply by a generator, providing foam water agent, ensuring communication, and transporting the fire-fighting unmanned aerial vehicle.

[0067] The specific use method is as follows:

[0068] (1) According to the fire situation, determine the fire-fighting unmanned aerial vehicle group and the fire truck group;

[0069] (2) Each fire-fighting unmanned aerial vehicle group includes one fire-fighting unmanned aerial vehicle and more than one auxiliary fire-fighting unmanned aerial vehicle; the fire-fighting unmanned aerial vehicle and the auxiliary fire-fighting unmanned aerial vehicle are connected in series through a fire hose;

[0070] (3) Control the fire-fighting unmanned aerial vehicle in front to approach the fire source, and control the auxiliary fire-fighting unmanned aerial vehicle to adjust the distance between the fire-fighting unmanned aerial vehicle and the auxiliary fire-fighting unmanned aerial vehicle and the distance between the auxiliary fire-fighting unmanned aerial vehicles. At the same time, control the auxiliary fire-fighting unmanned aerial vehicle to make the fire hose away from the walls on the top of the high-rise building to avoid scratching the fire hose.

[0071] (4) And parallel between different fire-fighting unmanned aerial vehicle groups.

[0072] The above only describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
