[0001] The present invention relates to the technical field of fire-fighting unmanned aerial vehicles (UAVs), in particular to a fire-fighting unmanned aerial vehicle (UAV). Background Art

[0002] In modern firefighting operations, firefighting drones play an increasingly important role. However, there are many shortcomings in the current connection methods between drones and water tanks on the market. Traditional connection methods are mostly simple bundling or fixed connections. In this way, the water tank and the drone are not convenient to disassemble. The water tank needs to be refilled every time the drone flies back. The traditional connection method is extremely inconvenient in loading and unloading the water tank. The drone needs to wait for the water to fill up, which affects the efficiency of firefighting.

[0003] In actual firefighting operations, it may be necessary to replace water tanks of different capacities in a timely manner according to the size of the fire and the needs of fire extinguishing. The traditional connection method makes this process time-consuming, often missing the best time to extinguish the fire, greatly reducing the fire extinguishing efficiency.

Because the positioning sleeve 143 is arranged in a funnel shape, the positioning sleeve 143 will drive the positioning rod 144 to approach the axis of the positioning sleeve 143, thereby driving the drone device 3 to move. When the positioning rod 144 passes through the center of the positioning sleeve 143, the magnet A34 on the expansion plate 33 is aligned with the corresponding magnet B35 and adsorbed.

The electric telescopic rod 141 is engaged and fixed. When the UAV equipment 3 needs to take off, the electric telescopic rod 141 rises to separate the positioning sleeve 143 from the positioning rod 144, and the electric telescopic rod 152 extends to drive the electric telescopic rod 141 to rotate clockwise, driving the connecting rod 142 to rotate to the right, and then the motor 131 continues to move to raise the motor 131, pushing the water spraying mechanism 2 upward through the discharge hole, and then the UAV equipment 3 takes off and drives the water spraying mechanism 2 to fly to the specified position, and then the motor 131 reverses and drives the adjustment plate 133 to reset, and then the new water spraying mechanism 2 driving the card column 164 is placed on the adjustment plate 133 through the feed hole of the left support platform 11.

[0037] Working principle:

[0038] When the device is in use, when the drone device 3 stops on the support platform 11, the expansion plate 33 should be placed on the support platform 11 on both sides, and the expansion plate 33 presses the magnet B35, and the magnet A34 is roughly aligned with the magnet B35, and then the electric telescopic rod 152 on the bracket 151 is retracted to drive the rack 153 to move to the right, and the rack 153 moves to the right to drive the gear 154 to rotate counterclockwise, and the gear 154 rotates counterclockwise to drive the electric telescopic rod 141 to rotate counterclockwise, thereby driving the connecting rod 142 to rotate, so that the positioning sleeve 143 moves to the top of the positioning rod 144 on the drone device 3, and then the electric telescopic rod 141 is retracted to drive the connecting rod 142 to move downward, and the connecting rod 142 drives the positioning sleeve 143 to move downward, and the positioning sleeve 143 covers the positioning rod 144 downward on the outside of the positioning sleeve 143 and allows the positioning rod 144 to pass through the positioning sleeve 143, because the positioning sleeve 143 is a funnel. The positioning sleeve 143 is arranged in a shape, and the positioning sleeve 143 will drive the positioning rod 144 to approach the axis of the positioning sleeve 143, thereby driving the UAV device 3 to move. When the positioning rod 144 passes through the center of the positioning sleeve 143, the magnet A34 on the expansion plate 33 is aligned with the corresponding magnet B35 and adsorbed. At this time, the card column 164 is aligned with the connecting groove of the expansion plate 33, thereby accurately positioning the UAV device 3. Then, the motor 131 on the fixed plate 134 drives the threaded rod 132 to rotate on the support platform 11. Through the limitation of the adjusting plate 133 by the right support platform 11, the threaded rod 132 drives the adjusting plate 133 to move upward. The adjusting plate 133 drags the water spraying mechanism 2 upward to move upward, thereby driving the card block 163 to move upward. The card block 163 passes through the connecting groove of the expansion plate 33. At this time, the spring 161 pushes the push block 162 to drive the card block 163 to insert into the card slot of the card column 164, thereby locking and fixing the card column 164 and the expansion plate 33.

[0039] When the drone device 3 needs to take off, the electric telescopic rod 141 rises to separate the positioning sleeve 143 from the positioning rod 144, and the electric telescopic rod 152 extends to drive the electric telescopic rod 141 to rotate clockwise, driving the connecting rod 142 to rotate to the right, and then the motor 131 continues to move to make the motor 131 rise, pushing the water spraying mechanism 2 upward through the discharge hole, and then the drone device 3 takes off and drives the water spraying mechanism 2 to fly to the designated position. Then the motor 131 reverses and drives the adjustment plate 133 to reset, and the new water spraying mechanism 2 driving the clamping column 164 is placed on the adjustment plate 133 through the feed hole of the left support platform 11. After the workbench 1 used by the water spraying mechanism 2 is returned to the designated place for placing the water spraying mechanism 2, the staff toggles the lever 165 to drive the push block 162 away from the clamping column 164, so that the clamping block 163 is separated from the clamping column 164, thereby separating the expansion plate 33 from the clamping column 164, and then the aircraft runs to fly to the support platform 11.
