Abstract
Description
Technical Field
[0001] This utility model relates to a high-altitude fire extinguishing device for drones, belonging to the field of drone technology. Background Technology
[0002] Firefighting and rescue operations in high-rise buildings have always been a global challenge. To address these challenges, the use of firefighting and rescue drones has become an irreversible trend. On the one hand, they can quickly reach the fire site regardless of terrain or altitude, and on the other hand, they provide maximum protection for the safety of rescue personnel.
[0003] Currently, the structure of drone-based high-altitude firefighting systems mostly involves mounting a fire hose at the bottom of the drone, which is connected to a long water pipe. The other end of the pipe is connected to various water sources at the fire scene or to a fire truck on site. Depending on the different environments and altitudes of the fire scene, the distance the drone needs to move laterally also varies, meaning the required length of the fire hose also varies. If it's too short, it cannot reach the designated altitude, and lateral movement requires the assistance of a fire truck, affecting efficiency; if it's too long, the fire hose becomes cluttered at the scene, easily damaged, and prone to accidental entanglement. Utility Model Content
[0004] The purpose of this invention is to solve the technical problem in the prior art where fire hoses that are too short or too long affect the fire extinguishing effect, and to provide a drone-based high-altitude fire extinguishing device.
[0005] This utility model is achieved through the following technical solution:
[0006] A type of high-altitude firefighting equipment for drones includes a drone body, a fire hose receiving mechanism installed at the bottom of the drone body, a U-shaped rod, a support rod fixed at one end of the U-shaped rod, a connecting water pipe fixed at the other end of the U-shaped rod, a circular baffle rotatably mounted on the support rod, a pulley at the center of the circular baffle, the pulley being connected to a motor installed at the bottom of the drone body, and a circular baffle rotatably mounted on the connecting water pipe, the two circular baffles being connected by multiple crossbars;
[0007] The outer end of the connecting water pipe is connected to the outlet pipe via a two-way threaded sleeve. A fire hose is installed at the end of the outlet pipe. The inner end of the connecting water pipe is connected to the second connecting water pipe via a rotatable pipe connector. The end of the second connecting water pipe is connected to the fire hose via a clamp. The fire hose passes through the gaps in the crossbars and is wrapped around multiple crossbars.
[0008] The motor at the bottom of the drone drives the circular baffle and crossbar to rotate together via a belt drive mechanism. The fire hose and fire nozzle are connected by a rotatable pipe connector to accommodate the rotation of the fire hose when it is wrapped around the crossbar. The tail end of the fire hose is connected to a water source on the ground. The fire hose can be extended and retracted according to different fire conditions, ensuring the fire extinguishing effect while reducing the possibility of accidental damage or entanglement of the fire hose.
[0009] Further optimization reveals that the rotatable pipe connection joint includes a semi-circular shell integrally formed at the inner end of a connecting water pipe and a hollow ball head integrally formed at the outer end of a connecting water pipe. The hollow ball head is installed inside the semi-circular shell, and the semi-circular shell and the locking semi-circular shell are connected by bolts to limit and lock the hollow ball head. This rotatable pipe connection joint, employing the above structure, enables relative rotation between the fire hose and the fire nozzle, and is simple and reliable in structure.
[0010] Further optimization involves installing a sealing gasket between the locking semi-circular shell and the semi-circular shell.
[0011] Further optimization involves all the crossbars forming a cylindrical cage-like structure, with a limiting ring welded inside each crossbar. The fire hose passes through the gap between the limiting ring and the crossbar and wraps around all the crossbars. This prevents the fire hose from being wrapped too tightly around the crossbars.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] The motor at the bottom of the drone drives the circular baffle and crossbar to rotate together via a belt drive mechanism. The fire hose and fire nozzle are connected by a rotatable pipe connector to accommodate the rotation of the fire hose when it is wrapped around the crossbar. The tail end of the fire hose is connected to a water source on the ground. The fire hose can be extended and retracted according to different fire conditions, ensuring the fire extinguishing effect while reducing the possibility of accidental damage or entanglement of the fire hose.

[0020] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0021] like Figures 1 to 4 The above-mentioned drone high-altitude fire extinguishing equipment includes a drone body 1. A fire hose receiving mechanism 2 is installed at the bottom of the drone body 1. The fire hose receiving mechanism 2 includes a U-shaped rod 5. A support rod 6 is fixedly provided at one end of the U-shaped rod 5. A connecting water pipe 10 is fixedly provided at the other end of the U-shaped rod 5. A circular baffle 7 is rotatably installed on the support rod 6. A pulley 19 is provided at the center of the circular baffle 7. The pulley 19 is connected to a motor installed at the bottom of the drone body 1. A circular baffle 7 is also rotatably installed on the connecting water pipe 10. The two circular baffles 7 are connected by multiple crossbars 11.
[0022] The outer end of the connecting water pipe 10 is connected to the outlet pipe 8 via a two-way threaded sleeve 9. A fire nozzle 3 is installed at the end of the outlet pipe 8. The inner end of the connecting water pipe 10 is connected to the connecting water pipe 2 16 via a rotatable pipe connection joint 12. The end of the connecting water pipe 2 16 is connected to the fire hose 4 via a clamp. The fire hose 4 passes through the gaps in the crossbars 11 and is wrapped around multiple crossbars 11.
[0023] The motor at the bottom of the drone body 1 drives the circular baffle 7 and the crossbar 11 to rotate together via a belt drive mechanism. The fire hose 4 and the fire nozzle 3 are connected by a rotatable pipe connector 12 to accommodate the rotation of the fire hose 4 when it is wrapped around the crossbar 11. The tail end of the fire hose 4 is connected to a water source on the ground. The fire hose 4 can be extended and retracted according to different fire scene conditions, ensuring the fire extinguishing effect while reducing the possibility of accidental damage or entanglement of the fire hose 4.
[0024] The rotatable pipe connection joint 12 includes a semi-circular shell 14 integrally formed at the inner end of the connecting water pipe 10 and a hollow ball head 17 integrally formed at the outer end of the connecting water pipe 2 16. The hollow ball head 17 is installed inside the semi-circular shell 14. The semi-circular shell 14 and the locking semi-circular shell 18 are connected by bolts 15 to limit and lock the hollow ball head 17. A sealing gasket 20 is installed between the locking semi-circular shell 18 and the semi-circular shell 14. The rotatable pipe connection joint 12 adopts the above structure to realize the relative rotation between the fire hose 4 and the fire nozzle 3. The structure is simple and reliable.
[0025] All the crossbars 11 form a cylindrical cage-like structure, and a limiting ring 13 is welded inside each crossbar 11. The fire hose 4 passes through the gap between the limiting ring 13 and the crossbar 11 and wraps around all the crossbars 11. This prevents the fire hose 4 from being wrapped too tightly on the crossbars 11.
