[0021] Specifically, during firefighting and rescue, the electric push rod 509 is started, and the firefighting frame 513 is pushed to move by the electric push rod 509 to extend it. At the same time, when the firefighting frame 513 moves, the connecting cable 508 can be pulled, so that the connecting cable 508 pulls the movable block 507 and the balance frame 505 to extend in the opposite direction. At this time, the telescopic spring rod 506 is stretched, and the transmission belt 503 is gradually tightened due to the extension (when the transmission belt 503 is not tightened, it can be limited by the limiting belt rack 520 to prevent it from separating from the linkage wheel 516). When the transmission belt 503 is tightened, the firefighting drone sprays water through the fire sprinkler 502 to perform firefighting and rescue operations. At this time, when the water flows through the fire sprinkler 502, it can drive the water drive wheel 515 inside it to rotate, thereby driving one of the installation shafts 518 and the linkage wheel 516 to rotate.

[0022] Reference Figure 2 , Figure 3 , Figure 4 , Figure 8 and Fig. 9In a preferred embodiment, the water pipe anti-bending module 6 also includes a secondary water tank 603, which is fixedly connected to the inner walls of the two U-shaped frames 12, and a pressure pump 604 is fixedly connected to the outer wall of one side of the secondary water tank 603, and the output end of the pressure pump 604 is fixedly connected to the connecting water pipe 11, and the output end of the connecting water pipe 11 is fixedly connected to the input end of the fire sprinkler 502, and the outer wall of the other side of the secondary water tank 603 is fixedly connected to the fire water pipe 602 and the annular bracket 605, and the fire water pipe 602 passes through the annular bracket 605; the outer wall of one side of the annular bracket 605 is fixedly connected to two side plate brackets 601, and the inner walls of the opposite sides of the two side plate brackets 601 are movably connected to the same shaft rod 607, and the anti-bending arc frame 610 is fixedly connected to the outer wall of the shaft rod 607 The outer wall of the fire water pipe 602 is in contact with the inner wall of the anti-bending frame 610, and the inner walls on the opposite sides of the two side plate brackets 601 are movably connected with the same mounting rod 613; the outer wall of the mounting rod 613 is fixedly connected with two adjusting reels 612, and the two adjusting reels 612 are each provided with a connecting cable 609, and one end of the two connecting cables 609 is fixedly connected with a connecting member 608, and the two connecting members 608 are respectively fixedly connected to the outer walls on both sides of the anti-bending frame 610, and the outer wall on one side of one side plate bracket 601 is fixedly connected with a universal motor 611, and the output shaft of the universal motor 611 is connected to one end of the mounting rod 613 through a coupling, and the secondary water tank 603 is fixedly connected with the outer wall on the opposite side of the anti-bending frame 610 with the same connecting soft belt 606.

[0023] Specifically, when in use, the fire hose 602 is connected to the secondary water tank 603, and the fire hose 602 is set on the anti-bending frame 610 to guide it in an arc shape to prevent the fire hose 602 from bending. Then the fire-fighting drone rises to perform firefighting and rescue operations. When the fire-fighting drone rises, the universal motor 611 is started, and the universal motor 611 drives the installation rod 613 and the adjustment reel 612 to rotate, so as to reel in or loosen the connecting cable 609. As the connecting cable 609 is reeled in or loosened, the anti-bending frame 610 can be driven to rotate, so as to make real-time adjustments according to the height of the fire-fighting drone, to ensure the arc-guiding effect of the anti-bending frame 610 on the fire hose 602. When performing rescue, the fire-fighting water is transported to the secondary water tank 603 through the fire hose 602, and is pressurized and transported by the pressure pump 604 on the secondary water tank 603, and is transported to the fire sprinkler 502 through the connecting water pipe 11 for use in firefighting and rescue. In a specific application scenario, the water pipe anti-bending module 6 is suitable for the connection and use of the fire water pipe 602, that is, it can guide the fire water pipe 602 connected to the ground and the secondary water tank 603 in an arc shape to prevent the fire water pipe 602 from bending at the connection part with the secondary water tank 603 due to gravity when the fire-fighting drone is running at high altitude, thereby avoiding the bending from affecting the water flow, so as to ensure a stable supply of water flow during firefighting and rescue, and increase the use effect of the device. When in use, the water pipe anti-bending module 6 can perform secondary pressurization on the delivered water flow through the secondary water tank 603 and the pressure pump 604 to ensure that the water flow is always in a high-pressure state during firefighting and rescue, and avoid insufficient water pressure due to the high position of the fire-fighting drone, so as to further increase the firefighting and rescue effect of the device.

[0024] Reference Figure 3 and Fig.10 In a preferred embodiment, the landing buffer module 10 also includes four fixed rings 1004, which are respectively fixedly connected to the outer walls of the two cross bars 13, and one side outer wall of the four fixed rings 1004 is fixedly connected with three buffer spring rods 1003, and one end of the three buffer spring rods 1003 on the same fixed ring 1004 is fixedly connected with the same movable ring 1001, and one side outer wall of the four movable rings 1001 is fixedly connected with a buffer connecting plate 1008; the two buffer connecting plates 1008 on the same cross bar 13 are fixedly connected to the same elastic sheet 1002 on the outer wall on the opposite side, and two elastic buffer members 1007 are respectively arranged on the two elastic sheets 1002, and the bottom ends of the two support frames 4 are fixedly connected with landing support rods 1006, and three anti-slip sleeves 1005 are arranged on the two landing support rods 1006.

[0025] Specifically, when landing, the elastic buffer 1007 first contacts the ground and transmits the force to the buffer plate 1008 through the elastic sheet 1002 (the elastic buffer 1007 and the elastic sheet 1002 can initially buffer and reduce the force). At this time, the buffer plate 1008 can drive the movable ring 1001 to move on the crossbar 13, thereby compressing the buffer spring rod 1003. Then the buffer spring rod 1003 recovers and performs secondary buffering through the damper provided by itself until the firefighting drone completes the landing (when landing, the anti-skid cover 1005 can prevent the firefighting drone from slipping, further increasing the landing stability of the device); In a specific application scenario, the landing buffer module 10 is suitable for the landing of a fire-fighting UAV, that is, the landing buffer module 10 can buffer the fire-fighting UAV when it is landing, thereby preventing it from making strong contact with the ground during landing, thereby ensuring the stability of the fire-fighting UAV during landing. At the same time, the buffering during landing can reduce the vibration or shaking of the fire-fighting UAV, thereby preventing the parts of the fire-fighting UAV from loosening, thereby increasing the service life of the device, and avoiding damage to the fire-fighting UAV during landing, thereby improving the use effect of the device.

[0026] Working principle: When in use, the fire hose 602 is connected to the secondary water tank 603, and the fire hose 602 is set on the anti-bending frame 610 to guide it in an arc shape to prevent the fire hose 602 from bending. Then the fire-fighting drone rises to perform firefighting and rescue operations. When the fire-fighting drone rises, the universal motor 611 is started, and the universal motor 611 drives the installation rod 613 and the adjustment reel 612 to rotate, so as to reel in or loosen the connecting cable 609. As the connecting cable 609 is reeled in or loosened, the anti-bending frame 610 can be driven to rotate, so as to make real-time adjustments according to the height of the fire-fighting drone, to ensure the arc-guiding effect of the anti-bending frame 610 on the fire hose 602, and when performing rescue, the fire-fighting water is transported to the secondary water tank 603 through the fire hose 602, and is pressurized and transported by the pressure pump 604 on the secondary water tank 603, and is transported to the fire sprinkler 502 through the connecting water pipe 11 for use in firefighting and rescue. During firefighting and rescue, the electric push rod 509 is started, and the firefighting frame 513 is pushed to move by the electric push rod 509 to extend it. At the same time, when the firefighting frame 513 moves, the connecting cable 508 can be pulled, so that the connecting cable 508 pulls the movable block 507 and the balance frame 505 to extend in the opposite direction. At this time, the telescopic spring rod 506 is stretched, and the transmission belt 503 is gradually tightened due to the extension. When the transmission belt 503 is tightened, the firefighting drone sprays water through the fire sprinkler 502 to perform firefighting and rescue operations. At this time, when the water flows through the fire sprinkler 502, it can drive the water drive wheel 515 inside it to rotate, thereby driving one of the installation shafts 518 and the linkage wheel 516 to rotate, and cooperate with the transmission belt 503 to enable the two linkage wheels 516 to rotate. The wind wheel 517 can be operated synchronously, so that the other linkage wheel 516 drives the wind wheel 517 to operate, so that the wind wheel 517 blows the wind into the air guide duct 504 and then enters the closed air duct 519. At this time, the shrinkage of the air outlet end of the closed air duct 519 will increase the wind speed, thereby generating a high-speed airflow to push the fire-fighting drone, and the pushing direction is opposite to the direction of the reaction force of the high-pressure water of the fire-fighting, so as to offset the reaction force of the high-pressure water, thereby maintaining the balance of the fire-fighting drone, and during the fire-fighting process, starting the servo motor 523 can drive the driving gear 522 to rotate, and because the driving gear 522 is meshed with the gear ring 521, it can drive the gear ring 521 and the annular frame seat 501 to rotate, so as to adjust the angle of the mounting frame 511, thereby changing the angle and position of the fire-fighting water spraying; During landing, the elastic buffer 1007 contacts the ground first and transfers the force to the buffer plate 1008 through the elastic sheet 1002. At this time, the buffer plate 1008 can drive the movable ring 1001 to move on the cross bar 13, thereby compressing the buffer spring rod 1003. The buffer spring rod 1003 then recovers and performs secondary buffering through the damper provided by itself until the fire-fighting drone completes its landing.
