Description

Technical Field

[0001] This invention belongs to the field of fire extinguishing technology using drones with landing gear that carry water hoses into the air, and specifically relates to a special transition structure for connecting the water hose to the end pipe of the drone body. Background Technology

[0002] In fields such as firefighting, high-altitude operations are involved, and drones play a crucial role in these hazardous environments. Most drones cannot simultaneously guarantee large payload capacity and long endurance, making tethered drones a significant advantage for continuous operation in these areas. Firefighting operations require large flow rates, and most drones are equipped with fixed spray guns; current technology cannot guarantee precise cleaning by simultaneously aiming and adjusting the spray gun. Summary of the Invention

[0003] This invention designs a transitional structure combining traditional firefighting and precision spray cleaning. This structure ensures that the tethered drone can both tow the hose into the air and connect to the servo mechanism of the drone's end piping. The servo mechanism connected to the drone's end drives the spray gun's pitch, enabling simultaneous aiming and spraying for precise cleaning. Anti-slip pads are placed inside the hose clamps to increase friction between the structural clamps and the drone's landing gear. Through this transitional structure design, most of the weight of the hose in its fully loaded state is borne by the tethered drone itself, thereby improving the servo motor's driving capability and reducing its weight, thus achieving a lightweight design for the under-mounted load. Attached Figure Description

[0004] Appendix Figure 1 This is a schematic diagram of the structure.

[0005] As shown in the figure: landing gear support body (1), liquid conveying (2), upper water inlet double external thread port (3), lower water inlet water hose quick-connect port (4), landing gear fixing pipe clamp (5), anti-slip rubber pad (6), fastening threaded hole (7). Detailed Implementation

[0006] When using this transition structure, ensure the landing gear body faces upwards. After adjusting the position, secure the landing gear fixing clamps to the main body using M3 screws to improve the structure's towing capacity. The lower end of the structure can be connected to a quick-connect fitting with external threads, using either a KYK40 male or female connector. The upper end can be connected to a standard 1.5-inch external thread fitting of the same specification, currently designed to connect to a 1.5-inch double external thread fitting. It connects to the UAV's airframe piping and servo mechanism via an external thread adapter. During use, the ground end supplies liquid via a hose to the quick-connect port at the lower end of the structure, transitioning from the structure to the airframe's delivery pipeline, and then spraying it out through the spray gun. During this process, the servo mechanism can drive the spray gun to pitch, improving operational efficiency and accuracy.

Claims

1. A transition structure for connecting a drone's towed water hose to a pipe at the end of the drone body, characterized in that: It consists of a landing gear support body (1), a liquid delivery system (2), an upper water inlet double male threaded port (3), a lower water inlet hose quick-connect port (4), a landing gear fixing clamp (5), an anti-slip pad (6), and a fastening threaded hole (7). During use, ensure the landing gear body faces upwards. After adjusting the position, fasten the landing gear fixing clamp (5) to the main body using M3 screws. The lower end of the structure can be connected to a male threaded quick-connect connector; a KYK40 male connector or a KYK40 male connector can be selected. The K40 female plug can be connected to a standard 1.5-inch external thread component of the same specification at the upper end as required. It can be connected to the UAV body end pipeline and servo mechanism through the external thread adapter. The ground end is supplied with water through the water hose to the water hose quick-connect port (4) at the lower end of the structure. It is then transitioned from the structure to the conveying pipeline at the body end and sprayed out through the spray gun. The UAV can both drag the water hose into the air and connect to the servo mechanism of the body end pipeline. The servo mechanism can drive the spray gun to pitch and shoot, thereby improving the efficiency and accuracy of operation.
