[0022] The present invention will be further described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0023] like Figures 1-6 As shown, this embodiment provides a fire-fighting drone, including a drone body 1. A fire extinguishing agent storage box 2 is snapped onto the upper surface of the drone body 1. The drone body 1 is provided with a fixing component 3 for fixing the fire extinguishing agent storage box 2. The fixing component 3 can fix the fire extinguishing agent storage box 2 and prevent it from moving. A pump body 4 is provided on one side of the drone body 1. The water inlet end of the pump body 4 is threadedly connected to the fire extinguishing agent storage box 2. A fixing frame 5 is provided on the lower surface of the drone body 1. A reciprocating rotating fire extinguishing agent spraying component 6 is provided on the fixing frame 5. A motor 8 for driving the reciprocating rotating fire extinguishing agent spraying component 6 is connected to the fixing frame 5. The output end of the pump body 4 is connected to the reciprocating rotating fire extinguishing agent spraying component 6. Through the pump body 4, the fire extinguishing agent can be delivered into the reciprocating rotating fire extinguishing agent spraying component 6. Through the reciprocating rotating fire extinguishing agent spraying component 6, the fire extinguishing agent spraying area can be increased and the fire extinguishing efficiency can be improved.

[0024] The upper surface of the drone body 1 has a positioning groove 7. The fire extinguishing agent storage box 2 is snapped into the drone body 1 through the positioning groove 7. The fixing component 3 includes a fixing plate 301, which is fixedly installed on the upper surface of the drone body 1 and located on both sides of the positioning groove 7. A screw 302 is threaded onto the fixing plate 301. A clamping plate 303 is rotatably installed on the other end of the screw 302. A handwheel 304 is connected to the other end of the screw 302. Limiting rods 305 are connected to the clamping plate 303 on both sides of the screw 302. The limiting rods 305 are inserted into the fixing plate 301. The clamping plate 303 has a hollow internal structure. Suction cups 306 arranged in an array are connected to the clamping plate 303. An air pump 307 is provided on the fixing plate 301. The output end is connected to the output pipe 308, and the other end of the output pipe 308 is connected to the clamping plate 303. When the handwheel 304 at one end of the screw 302 is turned, the screw 302 rotates and pushes the clamping plate 303 closer to the fire extinguishing agent placement box 2. The limiting rods 305 on both sides of the clamping plate 303 slide smoothly along the insertion holes of the fixing plate 301 to ensure that the clamping plate 303 moves in parallel and applies force evenly. When the clamping plate 303 is in contact with the side of the fire extinguishing agent placement box 2, stop turning the handwheel 304 and start the air pump 307 on the fixing plate 301. The negative pressure is transmitted through the output pipe 308 to the hollow structure inside the clamping plate 303, so that the arrayed suction cups 306 generate a strong suction force to firmly fix the fire extinguishing agent placement box 2 and prevent it from shaking or shifting during flight and operation.

[0025] The reciprocating rotating fire extinguishing agent spraying assembly 6 includes a turntable 601 and a spray gun 602. The turntable 601 is connected to the output end of the motor 8, and the spray gun 602 is rotatably connected to the fixed frame 5. A connecting frame 603 is ball-hinged on the turntable 601 and rotatably connected to the spray gun 602. A feed pipe 604 is connected to the spray gun 602 and is connected to the output end of the pump body 4. The feed pipe 604 is made of flexible hose. A support frame 9 is connected to the drone body 1. When the motor 8 is started, the motor 8 drives the turntable 601 to rotate, and the connecting frame 603 hinged to it moves accordingly, causing the spray gun 602 to reciprocate, increasing the fire extinguishing agent spraying range and improving the fire extinguishing efficiency. When the pump body 4 is started, the pump body 4 draws the fire extinguishing agent from the fire extinguishing agent storage box 2, pressurizes it, and sends it to the feed pipe 604 through the output end.

[0026] In use, the drone is transported to a safe, open area near the fire scene. The extinguishing agent placement box 2 is aligned with the positioning groove 7 on the upper surface of the drone body 1 and slowly lowered to engage. The handwheel 304 at one end of the screw 302 is turned, causing the screw 302 to rotate and push the clamping plate 303 closer to the extinguishing agent placement box 2. The limiting rods 305 on both sides of the clamping plate 303 slide smoothly along the insertion holes of the fixing plate 301, ensuring that the clamping plate 303 moves parallel and applies force evenly. Once the clamping plate 303 is in contact with the side of the extinguishing agent placement box 2, the handwheel 304 is stopped, and the air pump 307 on the fixing plate 301 is started. The negative pressure is transmitted through the output pipe 308 to the hollow structure inside the clamping plate 303, causing the arrayed suction cups 306 to generate a strong suction. Securely fasten the extinguishing agent storage tank 2 to prevent shaking or displacement during flight and operation. Tighten the water inlet of the pump body 4 to the outlet of the extinguishing agent storage tank 2 to ensure a tight and leak-free connection. The operator controls the drone to take off via remote control. After reaching a suitable position above the fire area, the operator issues a command to start the pump body 4. The pump body 4 draws the extinguishing agent from the extinguishing agent storage tank 2, pressurizes it, and sends it to the feed pipe 604 through the output end. Since the feed pipe 604 is a flexible hose, it can bend flexibly with the spray gun 602 to ensure stable delivery of the extinguishing agent. At the same time, the motor 8 is started, which drives the turntable 601 to rotate. The connecting frame 603, which is hinged to it, moves accordingly, causing the spray gun 602 to reciprocate, increasing the spray range of the extinguishing agent and improving the extinguishing efficiency.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this invention. Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention. Various changes and modifications may be made to this invention without departing from its spirit and scope. All such changes and modifications fall within the scope of this invention as defined by the appended claims and their equivalents.
