[0052] The high-altitude fire extinguishing and rescue device according to the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0053] The high-altitude fire extinguishing and rescue device provided in the embodiments of the present invention includes: a drone body 10, a conveying mechanism 20, and a robot 30. The conveying mechanism 20 is arranged below the drone body 10 and can be extended or shortened along a predetermined direction; the robot 30 is movably loaded on the conveying mechanism 20, and can be switched between a locked state and an unlocked state with the conveying mechanism 20; when the robot 30 is loaded on the conveying mechanism 20, the robot 30 and the conveying mechanism 20 are in a locked state; when the robot 30 is transported to a predetermined position by the conveying mechanism 20, the robot 30 and the conveying mechanism 20 are in an unlocked state.

[0054] Among them, the drone body 10 may be a load-carrying drone, etc., and the predetermined position may be a position to be extinguished or a position to be rescued, etc. For example Figure 2The conveying frame 21 shown in the figure extends into the window. Thus, the robot 30 can be loaded and conveyed into the window through the conveying mechanism 20, or rescue materials can be conveyed into the window. The drone body 10 lifts the robot 30 loaded on the conveying frame 21 to a high altitude position, and the conveying mechanism 20 extends to drive the robot 30 to be conveyed to a predetermined position, enabling the drone body 10 to convey the robot 30 over a long distance for fire extinguishing or rescue, avoiding the unstable flight of the drone body 10 caused by the heat flow. It can be understood that by locking between the robot 30 and the conveying mechanism 20, the robot 30 can be more stable and reliable during the lifting or moving process on the conveying mechanism 20, and when the robot 30 is conveyed to a predetermined position, the robot 30 can be quickly unlocked to complete the work of fire extinguishing or rescue.

[0055] The high-altitude fire extinguishing and rescue device provided by the present invention can drive the robot 30 to lift off by the drone body 10 and approach the fire area, and then drive the conveying mechanism 20 to extend to convey the robot 30 to a predetermined position. Thus, long-distance conveyance can be completed, and when a fire occurs in a high-rise building, a rapid rescue and fire extinguishing passage can be opened in the air, rescue materials can be delivered, time can be gained for ground fire fighting and rescue, and at the same time, the internal situation of the fire scene can be investigated through the robot 30, providing real-time intelligence for rescue and fire extinguishing command.

[0056] Specifically, the conveying mechanism 20 includes: a plurality of sliding frames 31, a slide rail motor 22, and a loading frame 23. The plurality of sliding frames 31 are slidably connected to each other and are provided at the bottom of the drone body 10. The slide rail motors 22 are respectively provided on each sliding frame 31 and are connected to the adjacent sliding frames 31 to drive the adjacent sliding frames 31 to move. The loading frame 23 is movably provided on the sliding frame 31, and the robot 30 is detachably loaded between the loading frames 23 and is detachably connected, so that the loading frame 23 drives the robot 30 to move.

[0057] In this embodiment, an installation plate 24 and a suspension frame 25 are provided at the bottom of the drone body 10. The installation plate 24 is fixed to the bottom of the drone body 10. The suspension frame 25 is provided at the bottom of the installation plate 24 and extends downward toward the installation plate 24. Among them, the installation plate 24 and the drone body 10 can be detachably connected, and the height of the suspension frame 25 can be set according to the robot 30, so that the robot 30 can move stably on the conveying frame 21.

[0058] Furthermore, the slide rail motor 22 can push the sliding frame 31 to extend or shorten, so that the multiple sliding frames 31 can extend to the position to be extinguished, enabling the robot 30 to move from the conveying frame 21 to the position to be extinguished. Thus, the drone body 10 can be prevented from approaching the fire area, improving the safety of the drone. The robot 30 can move on the conveying frame 21 along with the loading frame 23. After the sliding frame 31 extends to positions such as a window, the end of the sliding frame 31 away from the drone body 10 can face downward, allowing the loading frame 23 to slide downward to positions such as the window under its own gravity. When the loading frame 23 moves to the position to be extinguished, the robot 30 can detach from the loading frame 23 to complete the fire extinguishing or rescue work at a predetermined position through the robot 30.

[0059] Preferably, a wire winder 231 and a connecting rope 232 are provided on the loading frame 23. The first end of the connecting rope 232 is connected to the wire winder 231, and the second end is detachably connected to the robot 30. Further, a connecting member 233 is provided at the second end of the connecting rope 232, and the connecting member 233 is detachably connected to the robot 30.

[0060] In this embodiment, the connecting member 233 can be a hook or the like. Corresponding electromagnetic buckles 33 and connection ports 321 can be provided on the robot 30. The electromagnetic buckles 33 can extend into the connection ports 321, enabling the connecting member 233 to extend into the connection ports 321 and hook with the electromagnetic buckles 33. After the conveying frame 21 extends to positions such as a window, the connecting rope 232 can be released through the wire winder 231, allowing the robot 30 to be suspended and lowered from the loading frame 23. Thus, when it is necessary to detach the robot 30 from the loading frame 23, the connecting member 233 and the electromagnetic buckles 33 can be disengaged from each other, and the robot 30 can be controlled to complete the fire extinguishing or rescue operation, making the overall fire extinguishing and rescue operation simpler and safer.

[0061] Furthermore, limit wheels 234 are provided at the bottom of the loading frame 23, and the limit wheels 234 are engaged with the sliding frame 31 to limit the movement of the loading frame 23 on the sliding frame 31. Among them, grooves or stepped surfaces corresponding to the limit wheels 234 are provided on the conveying frame 21, enabling the limit wheels 234 to be engaged with the grooves or stepped surfaces. Thus, after the conveying frame 21 extends, the loading frame 23 can slide to positions such as a window by itself, making the engagement between the loading frame 23 and the conveying frame 21 more stable and the movement of the loading frame 23 more stable and reliable.

[0062] Specifically, the robot 30 includes: a robot main body 31, a connecting bracket 32, an electromagnetic buckle 33, and a fire extinguishing component 34. The connecting bracket 32 is provided on the robot main body 31; the electromagnetic buckle 33 is provided on the connecting bracket 32 and is used to control the switching between the locked state and the unlocked state of the connecting bracket 32 and the connecting member 233; the fire extinguishing component 34 is provided on the robot main body 31 and is used to spray a fire extinguishing agent towards the position to be extinguished during operation.

[0063] In this embodiment, when the connecting member 233 extends into the connection port 321, the electromagnetic buckle 33 can be controlled to extend into the connection port 321 and switch to the locked state to be locked with the connecting member 233, so that the robot 30 has better stability when being driven into the air by the UAV body 10 or moving with the loading rack 23; when the robot 30 needs to be released, the electromagnetic buckle 33 can be controlled to switch to the unlocked state, so that the hook can be detached from the connection port 321, and then the robot 30 can enter the position to be extinguished or the position to be rescued to work, with higher rescue efficiency and stronger coordination.

[0064] Specifically, the fire extinguishing component 34 includes: a water spray gun head 341 and a connecting hose 342. The water spray gun head 341 is provided on the robot main body 31; the connecting hose 342 is detachably connected to the water spray gun head 341 to convey the fire extinguishing agent through the water spray gun head 341.

[0065] In this embodiment, the fire extinguishing agent can be water, foam fire extinguishing agent, dry powder fire extinguishing agent, etc. The water spray gun head 341 can be connected to the connecting hose 342, and water is conveyed through the connecting hose 342 and sprayed out from the water spray gun head 341; it can be understood that the connecting hose 342 can also convey other fire extinguishing agents to extinguish different fires, ensuring a wider scope of application.

[0066] Preferably, the connecting hose 342 is provided with limiting barbs 3421 at intervals along the length direction, and the limiting barbs 3421 are used to hook and fix the connecting hose 342. Among them, the limiting barbs 3421 can be used to hook on various bearing objects, such as on the wall, on the windowsill, etc., so as to ensure that the connecting hose 342 is more stable when connected to the water spray gun head 341 and avoid loosening.

[0067] Preferably, the fire extinguishing component 34 includes: a loading bucket 343, a spray head 344, and an acceleration component 345. The loading bucket 343 is provided on the robot main body 31 and is used to load the fire extinguishing balls 50; the spray head 344 is communicated with the loading bucket 343; the acceleration component 345 is provided on both sides of the spray head 344 and is used to accelerate the fire extinguishing balls 50 entering the spray head 344 and spray them out.

[0068] In this embodiment, the fire extinguishing ball 50 is filled with a fire extinguishing agent, which can release an aerosol fire extinguishing agent, etc. when encountering fire. The loading bucket 343 can load multiple fire extinguishing balls 50. After the speed increasing component 345 speeds up and ejects the fire extinguishing ball 50 in the ejection head 344, the fire extinguishing balls 50 in the loading bucket 343 can roll into the ejection head 344 by their own gravity and are sequentially ejected after being speeded up by the speed increasing component 345, thereby making the fire extinguishing efficiency higher and the safety higher.

[0069] Preferably, the speed increasing component 345 includes: a motor 3451 and a flywheel 3452. The motor 3451 is arranged on both sides of the ejection head 344; the flywheel 3452 is arranged on the motor 3451 and is embedded in the ejection head 344 along its radial direction for driving the fire extinguishing ball 50 to be ejected out of the ejection head 344 when rotating.

[0070] In this embodiment, openings are provided on both sides of the ejection head 344. The flywheel 3452 can extend into the ejection head 344 through the openings to fit with the fire extinguishing ball 50, so that after the flywheel 3452 is driven by the motor 3451 to rotate, it can apply an acceleration to the fire extinguishing ball 50, so that the fire extinguishing ball 50 is ejected from the ejection head 344, and the fire extinguishing agent is released to the fire area through the fire extinguishing ball 50 to complete the fire extinguishing operation, thereby ensuring higher fire extinguishing efficiency and a wider application range.

[0071] As an alternative embodiment, a robotic arm 60 is further provided on the robot body 31. The robotic arm 60 is rotatably arranged on the robot body 31. Among them, the robotic arm 60 can grab and connect the water hose 342 and the water spray gun head 341 for connection and fixation, can also grab and place the fire extinguishing ball 50 in the loading bucket 343, and can also grab and transport rescue materials or items to be rescued, so that the above-mentioned fire extinguishing and rescue robot 30 can be applied to different fire extinguishing and rescue scenarios.
