[0002] As is well known, drone firefighting, as a new industrial technology, has been widely applied in various fields. In China, many fire departments have successfully used drones for fire scene reconnaissance and monitoring, and for dropping rescue supplies, with very significant results. The role of drones is not limited to disaster reconnaissance; during a fire, firefighting drones can also replace firefighters in some firefighting operations, compensating for situations where firefighters cannot directly extinguish the fire due to the geographical limitations of buildings.

[0003] The existing utility model patent CN215461560U proposes a fire hose anti-detachment mounting device for fire-fighting drones. This utility model locks and fixes both ends of the hose by setting an installation cylinder, spring clamp and connecting nut on the bottom support frame of the drone, so as to prevent the hose from falling off during flight spraying.

[0004] As described in the above technical solution, since the water gun is fixed, during the fire extinguishing process, it is necessary to operate the drone to aim at the base of the fire source and frequently control the drone's hovering position to compensate for the angle. This increases the flight control load and collision risk, affecting the fire extinguishing efficiency. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1-3This application proposes a fire hose lifting platform for mounting a fire hose 1. The fire hose lifting platform includes a frame 2, a mounting component 3, and an adjusting component 4.

[0035] like Figure 1 As shown, the frame 2 is used to connect to the drone; the fire hose 1 includes a water supply pipe 11 and a fire nozzle 12. The water supply pipe 11 is located inside the frame 2, and one end is connected to an external water supply system; the fire nozzle 12 is movably connected to the other end of the water supply pipe 11; the mounting component 3 is fixed inside the frame 2 and is used to mount and fix the water supply pipe 11; the adjusting component 4 is located at one end of the corresponding fire nozzle 12 on the frame 2 and is connected to the fire nozzle 12 to adjust the spray angle of the fire nozzle 12.

[0036] Specifically, the rigid fixing of the fire hose 1 and the adjustable angle of the fire hose 1 are combined into the same landing gear; the water supply pipe 11 is firmly locked by the mounting component 3 to ensure no shaking under high water pressure; the fire nozzle 12 obtains pitch freedom through the movable joint; when extinguishing a fire, the drone only needs to keep it roughly hovering, and the adjusting component 4 will make fine adjustments to the nozzle angle to directly aim at the root of the fire source, avoiding the need for the drone to frequently adjust its hovering position, which would bring flight control load and collision risk, thereby significantly improving fire extinguishing efficiency and safety.

[0037] In some embodiments, such as Figure 1-2 As shown, the fire hose 1 also includes a connecting hose 13, a first connecting bracket 14, and a second connecting bracket 15. The connecting hose 13 is respectively sleeved on the end of the fire nozzle 12 opposite to the water supply pipe 11, for connecting the water supply pipe 11 and the fire nozzle 12. The first connecting bracket 14 is fixedly installed on the end of the fire nozzle 12 corresponding to the water supply pipe 11. The second connecting bracket 15 is fixedly installed on the end of the water supply pipe 11 corresponding to the first connecting bracket 14, and is hinged to the first connecting bracket 14.

[0038] Specifically, the connecting hose 13 forms a highly elastic transition between the water supply pipe 11 and the fire sprinkler pipe 12, allowing free bending within a finely adjusted angle with zero leakage; the first connecting bracket 14 and the second connecting bracket 15 form a hinged double bracket, directly transmitting the reaction torque of the sprinkler pipe to the frame 2, eliminating lateral bending moment, protecting the connecting hose 13 and the electric push rod 42, while the hinge method supports quick on-site disassembly and assembly, greatly shortening maintenance time.

[0039] like Figure 1 As shown, the adjusting component 4 includes a mounting block 41 and an electric push rod 42. The mounting block 41 is fixedly mounted on the fire sprinkler pipe 12. The electric push rod 42 includes two rods, which are symmetrically arranged on the frame 2 on both sides of the fire sprinkler pipe 12. One end is hinged to the frame 2, and the other end extends to the mounting block 41 and is hinged thereto, for driving the fire sprinkler pipe 12 to adjust its angle. The end of the electric push rod 42 connected to the frame 2 is located at the bottom of the fire sprinkler pipe 12.

[0040] Specifically, the opposing push setting of the dual electric push rods 42 forms a force couple, enabling the fire nozzle 12 to swing precisely and reduce errors; the hinge point between the electric push rods 42 and the frame 2 is located below the fire nozzle 12, which lowers the overall center of gravity, significantly reduces the pitch moment of the UAV, and completely avoids the field of view above the nozzle, without obstructing the airborne sensors, thus achieving efficient and low-disturbance fingertip angle fine adjustment.

[0041] like Figure 1 As shown, the adjusting component 4 also includes a PLC controller 43, which is mounted on the frame 2 and electrically connected to the electric push rod 42, and connected to the signal of external control equipment; this allows the operator to control the angle of the fire sprinkler 12 from the ground, improving the convenience and efficiency of operation.

[0042] like Figure 1 , Figure 3 As shown, the mounting component 3 includes a first mounting plate 31, mounting posts 32, mounting clips 33, and a second mounting plate 34. The first mounting plate 31 is located inside the frame 2 and has a clearance hole 301 for the water supply pipe 11 to extend downward and connect to the external water supply system. Multiple mounting posts 32 are located on the top periphery of the first mounting plate 31 and are used to connect to the top of the frame 2. The mounting clips 33 are detachably mounted on the first mounting plate 31 and are used to fix the water supply pipe 11. The second mounting plate 34 is detachably mounted on the top of the frame 2 and is fixedly connected to the top of the multiple mounting posts 32.

[0043] Specifically, the bypass hole 301 and the mounting block 33 are structurally compatible with different pipe diameters, allowing for quick on-site replacement of water guns; the combination of the second mounting plate 34 and the mounting column 32 significantly improves the overall rigidity, resisting jet backlash, while the detachable installation allows for quick maintenance, enabling rapid entry into the fire scene for continuous operation.

[0044] Workflow: After the drone hovers, the water supply pipe 11 is quickly locked by the first mounting plate 31 and connected to the external water source. The water flows into the fire sprinkler pipe 12 through the connecting hose 13. The PLC controller 43 receives the ground command and drives the symmetrical low-position electric push rod 42 to extend and retract synchronously with the help of the hinge bracket, so that the fire sprinkler pipe 12 can be adjusted in pitch within a certain range to continuously spray water at the base of the fire source. After the mission is completed, the entire water gun assembly can be quickly removed by loosening the mounting clip 33 to complete the replenishment or replacement.
