[0029] Reference Figure 1-3A drone-mounted bucket-lifted fire extinguishing device for firefighting includes: a bucket 10, a sealed box 11, a telescopic motor 13, bucket legs 14, lifting rings 15, and a sling 16. The bucket 10 is a cylindrical structure. Four circumferentially distributed lifting rings 15 are fixed to the outer wall of the upper end of the bucket 10. The sling 16 is connected to the lifting rings 15 via a locking buckle. During operation, the drone lifts the bucket 10 using the sling 16. A drain outlet 25 is provided at the lower end of the bucket 10. A telescopic motor 13 is fixed to the bucket 10. The telescopic rod end of the telescopic motor 13 is fixedly connected to a motor extension rod 20. A sealing plug 24 is fixedly connected to one end of the motor extension rod 20, and the sealing plug 24 faces the drain outlet 25 (the sealing plug 24 can be found in patent document CN101342501B). By controlling the extension and retraction of the piston rod of the telescopic motor 13, the sealing plug 24 can control the opening and closing of the drain outlet 25. When the drain outlet 25 is closed, water will not flow out of the drain outlet 25. When it is open, water can flow through the drain outlet 25.

[0030] A sealed box 11 is fixedly connected to the bucket 10. The wiring portion of the telescopic motor 13 (i.e., the upper end of the telescopic motor 13) is located inside the sealed box 11. A battery 21 and an electronic speed controller 22 are housed inside the sealed box 11. The battery 21 is electrically connected to the electronic speed controller 22, and the electronic speed controller 22 is electrically connected to the telescopic motor 13. The battery 21 provides power, and the electronic speed controller 22 controls the extension and retraction of the piston rod of the telescopic motor 13. A remote control signal receiver 23 is also located on the outside of the sealed box 11. The remote control signal receiver 23 is electrically connected to the electronic speed controller 22, receives wireless signals, and transmits the signals to the electronic speed controller 22. (The connection circuit can be found in the prior art of patent document CN118236649B.)

[0031] A fixing rod 19 located below the mounting rod 12 is fixed inside the bucket 10. The motor extension rod 20 passes through the fixing rod 19 and slides with the fixing rod 19. A sealing plug 24 is fixed at one end of the motor extension rod 20 that passes through the fixing rod 19. The sealing plug 24 is directly opposite the drain outlet 25. The fixing rod 19 guides the motor extension rod 20 to ensure stable movement of the motor extension rod 20.

[0032] The lower end of the bucket 10 is fixed with a bucket support 14. The bucket support 14 includes at least three support rods 17 and a support leg 18 fixed to the lower end of the support rods 17. The support rods 17 are evenly distributed around the axis of the bucket 10. The upper end of the support rods 17 is fixedly connected to the bucket 10. The support leg 18 has a ring structure and is located below the drain outlet 25, so that when the support leg 18 is supported on the ground, there is a certain distance between the drain outlet 25 and the ground.

[0033] The lower end of the bucket 10 is designed as a conical structure, and the outlet 25 is located at the apex of the conical structure and at the center of the bucket 10.

[0034] Working process or usage method: In the initial state, the telescopic motor 13 is in the retracted state, and the sealing plug 24 does not block the drain outlet 25.

[0035] 1. When working, when water needs to be collected, the drone will drop the bucket 10 into the water source area. When the bucket 10 is filled with water, it will send a wireless signal. After the remote control signal receiver 23 receives the wireless signal, it will transmit the signal to the electronic speed controller 22, thereby controlling the telescopic motor 13 to extend the telescopic rod, which will cause the sealing plug 24 to block the water outlet 25. At this time, the drone will suspend the bucket 10 to the designated area.

[0036] 2. When carrying out fire extinguishing operations, a wireless signal is emitted. After the remote control signal receiver 23 receives the wireless signal, it transmits the signal to the electronic speed controller 22, thereby controlling the telescopic rod of the telescopic motor 13 to retract, the sealing plug 24 does not block the water outlet 25, and water spraying begins, thereby carrying out fire extinguishing operations.

[0037] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
