[0034] More specifically, the drone first prepares to fly, carrying a fire extinguishing refill mechanism. The fire extinguishing tank 2 stores the fire extinguishing agent, and the spraying assembly 3 is in standby mode. After the drone flies to the fire source area, it activates the fire extinguishing refill mechanism, which delivers the fire extinguishing agent from the fire extinguishing tank 2 to the spraying assembly 3 through the refill pipe 4. The spraying assembly 3 accurately sprays the fire extinguishing agent onto the fire source area to extinguish the fire. Before or after the fire extinguishing process, if the refill pipe 4 or the unblocking pipe 5 becomes blocked, the unblocking mechanism is activated. The rotating sleeve 6 begins to rotate in both directions, driving the rotating push block 8 to slide along the rotating push groove 7. The limiting plate 9 ensures that the unblocking plate 21 unblocks inward, and the impurities in the unblocking pipe 5 are removed, keeping the fire extinguishing pipeline unobstructed. The outer rotating ring 11 drives the linkage ring 12 to rotate. The rotating support plate 15, through the action of the spring pin 14, ensures the stable rotation of the outer rotating ring 11 and the linkage ring 12, thereby ensuring the smooth operation of the entire unblocking system.

[0035] In summary, during the use or operation of the overall equipment: when the fire extinguishing agent addition mechanism is required, the fire extinguishing box 2 is installed on the main body 1 of the drone and is responsible for storing the fire extinguishing agent. The fire extinguishing agent in the box is added through the addition pipe 4. The spray assembly 3 is usually installed around the fire extinguishing box 2 and is responsible for evenly spraying the fire extinguishing agent onto the fire source. The design of the spray assembly 3 ensures the accurate delivery of the fire extinguishing agent and ensures the fire extinguishing effect. The unblocking pipe 5 is connected to the addition pipe 4 and its function is to keep the fire extinguishing addition pipe 4 unobstructed and prevent blockage caused by the accumulation of impurities or solidified substances after use.

[0036] When the unblocking mechanism needs to be added, the rotating sleeve 6 is limited and installed on the outer wall of the unblocking pipe 5, allowing it to rotate on the outer wall of the unblocking pipe 5. The rotation of the rotating sleeve 6 can drive the unblocking mechanism inside the unblocking pipe 5 to work. The rotary push groove 7 is set on the inner wall of the rotating sleeve 6, and the rotary push block 8 can rotate in the rotary push groove 7. When the rotating sleeve 6 rotates in the opposite direction, the rotary push block 8 will retract inward. The limiting plate 9 is installed at one end of the rotary push block 8. The limiting plate 9 contacts the inner wall of the unblocking pipe 5 to ensure that the range of movement of the rotary push block 8 in the unblocking pipe 5 is effectively limited. When the rotating sleeve 6 rotates, the limiting plate 9 ensures that the unblocking plate 21 and the rotary push block 8 can be effectively pushed forward and retracted to unblock the addition pipe 4 and remove residues that may cause blockage, so as to avoid difficulty in adding fire extinguishing agent.

[0037] When the auxiliary unblocking mechanism is in operation, the outer rotating ring 11 is limited and installed on the outer wall of the unblocking pipe 5. It can rotate freely and drive the linkage ring 12 to rotate, controlling the overall movement of the unblocking mechanism. The linkage ring 12 is installed at the top and bottom of the outer rotating ring 11 and is connected to the rotating sleeve 6. The linkage ring 12, through its cooperation with the rotating sleeve 6, drives the rotating sleeve 6 to rotate, thereby making the unblocking block inside the unblocking pipe 5 work. The outer fixed ring 13 is fixedly installed on the outer wall of the unblocking pipe 5, and the spring-loaded pin 14 is installed on the outer fixed ring 13. The spring-loaded pin 14 can push against the rotating support plate 15 step by step, so that the outer rotating ring 11 and the linkage ring 12 rotate stably on the outer wall of the unblocking pipe 5, ensuring the stability and effectiveness of the unblocking mechanism.

[0038] The drone first prepares to fly, carrying a fire extinguishing refill mechanism. The fire extinguishing tank 2 stores the fire extinguishing agent, and the spraying assembly 3 is in standby mode. After the drone flies to the fire source area, it activates the fire extinguishing refill mechanism, which delivers the fire extinguishing agent from the fire extinguishing tank 2 to the spraying assembly 3 through the refill pipe 4. The spraying assembly 3 accurately sprays the fire extinguishing agent onto the fire source area to extinguish the fire. Before or after the fire extinguishing process, if the refill pipe 4 or the unblocking pipe 5 becomes blocked, the unblocking mechanism is activated. The rotating sleeve 6 begins to rotate in both directions, driving the rotating push block 8 to slide along the rotating push groove 7. The limiting plate 9 ensures that the unblocking plate 21 unblocks inward, and the impurities in the unblocking pipe 5 are removed, keeping the fire extinguishing pipeline unobstructed. The outer rotating ring 11 drives the linkage ring 12 to rotate. The rotating support plate 15, through the action of the spring pin 14, ensures the stable rotation of the outer rotating ring 11 and the linkage ring 12, thereby ensuring the smooth operation of the entire unblocking system.
