[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] like Figures 1-6As shown, this embodiment provides a fire inspection drone, including a drone body 1 and a frame 2 fixedly connected to both sides of the bottom of the drone body 1. A rescue material delivery component 3 is provided on the top of the drone body 1. A positioning plate 4 is fixedly installed at the center of the bottom of the drone body 1. A drop-proof fire extinguisher delivery component 5 is provided on both sides of the bottom of the drone body 1. A fixing ring 6 with a threaded interface is connected to the drop-proof fire extinguisher delivery component 5. A bottle-type fire extinguisher 7 for fire extinguishing is fixedly installed in the fixing ring 6. A positioning component 8 is fixedly installed on both sides inside the frame 2. The positioning component 8 is used to position the bottle-type fire extinguisher 7 on one side of the positioning plate 4. Fire extinguishing bullet components 9 for fire extinguishing are fixedly connected to the outer walls of both sides of the frame 2. After the positioning component 8 is working, it can squeeze the bottle-type fire extinguisher 7 until the bottle-type fire extinguisher 7 is squeezed and fixed on the positioning plate 4, thus achieving the function of temporary positioning.

[0024] The relief supplies delivery component 3 includes a rectangular storage box 301 fixedly installed on the top of the drone body 1. One end of the rectangular storage box 301 has an opening. An opening motor 302 is fixedly installed on the outer wall of the rectangular storage box 301. A shielding cover 303 is fixedly installed on the output shaft of the opening motor 302. The shielding cover 303 is located at the opening at one end of the rectangular storage box 301. A push-out telescopic rod 304 is fixedly connected to the outer wall of the rectangular storage box 301. A supplies push-out plate 305 is installed on one end of the push-out telescopic rod 304. The supplies push-out plate 305 is located inside the rectangular storage box 301. The cooperation between the supplies push-out plate 305 and the push-out telescopic rod 304 can push out the supplies.

[0025] The drop-resistant fire extinguisher delivery assembly 5 includes positioning seats 501 fixedly installed on both sides of the bottom of the drone body 1. A receiver / exhaust motor 502 is fixedly installed on the outer wall of the positioning seat 501. A reel 503 is rotatably installed inside the positioning seat 501. The output shaft of the receiver / exhaust motor 502 is fixed to one end of the reel 503. A connecting rope 504 is wound around the reel 503. A threaded connector 505 is installed on one end of the connecting rope 504. A limit plate 506 is fixedly connected to the bottom of the positioning seat 501. The limit plate 506 has limit holes. One end of the connecting rope 504 passes through the limit holes, and the threaded connector 505 is screwed into the threaded interface on the fixing ring 6. A mounting block 507 with a groove on its top surface is fixedly connected to the outer wall of plate 506. A cutting motor 508 is fixedly connected to the outer wall of mounting block 507. A bidirectional lead screw 509 is fixedly installed on the output shaft of cutting motor 508, and the bidirectional lead screw 509 is located in the groove on the top surface of mounting block 507. A moving block 510 is threadedly connected to the bidirectional lead screw 509. A cutting blade 511 is fixedly connected to the top of moving block 510. After the connecting rope 504 is cut, one end of the connecting rope 504 is connected to the fixing ring 6 through a threaded joint 505. After the threaded joint 505 is disconnected from the fixing ring 6, the connecting rope 504 can be separated from the bottle fire extinguisher 7.

[0026] The positioning component 8 includes a positioning telescopic rod 801, which is fixedly installed on the inner side of the frame 2. An arc-shaped positioning block 802 is fixedly connected to one end of the positioning telescopic rod 801. The arc-shaped positioning block 802 fits against the outer side of the bottle-type fire extinguisher 7. When the arc-shaped positioning block 802 is pressed against the bottle-type fire extinguisher 7, it can be fixed. Conversely, it can be released from fixation.

[0027] The fire extinguishing bomb assembly 9 includes a fire extinguishing box 901 fixed to the outside of the frame 2 and filled with fire extinguishing bombs. An opening and closing telescopic rod 902 is connected to the outer wall of the frame 2 via an L-shaped support. A sealing plate 903 is installed on one end of the opening and closing telescopic rod 902. The sealing plate 903 is located below the fire extinguishing box 901. In the initial state, the sealing plate 903 can block the fire extinguishing bombs in the fire extinguishing box 901 to prevent them from falling. After the sealing plate 903 is displaced, the fire extinguishing bombs fall.

[0028] In use, upon discovering a fire, the user can launch the drone body 1. Upon arrival at the scene, the user can choose to drop fire extinguishing bombs or airdrop bottle-type fire extinguishers 7, depending on the situation. If fire extinguishing bombs are to be dropped, the user can retract the telescopic rod 902, causing the sealing plate 903 to shift. After the sealing plate 903 shifts, it releases the obstruction of the fire extinguishing bombs inside the fire extinguishing box 901, allowing the fire extinguishing bombs to fall. Upon reaching the fire source, the fire extinguishing bombs can extinguish the fire. If the location of the fire makes it inconvenient to place fire extinguishing bombs, and there are still people at the fire location, the user can move the positioning telescopic rod 801 to move the arc-shaped positioning block 802. When the arc-shaped positioning block 802 no longer presses against the bottle-type fire extinguisher 7, the fixation of the fire extinguisher can be released. Then, the user can move the retractor 502 to rotate the reel 503. At this time, the reel 503 can unwind the connecting rope 504. Under the action of gravity, the bottle-type fire extinguisher 7 can be lowered. When the bottle-type fire extinguisher 7 descends to the level of the object... When in contact with or at a certain height, the user can activate the cutting motor 508 to drive the bidirectional lead screw 509 to rotate in place. At this time, the two moving blocks 510 and the cutting blade 511 can move and approach each other. After the cutting blade 511 moves, the connecting rope 504 can be cut. After cutting, the bottle-type fire extinguisher 7 separates from the main body of the drone 1. The personnel below can hold the bottle-type fire extinguisher 7 to extinguish the fire. Since the bottle-type fire extinguisher 7 is not directly airdropped, the possibility of it becoming unusable due to being dropped is reduced, and its integrity can be better maintained, thereby ensuring that it can play a normal fire extinguishing role after arriving at the fire scene. In summary, it has multiple fire extinguishing methods and improves fire extinguishing efficiency. When airdropping rescue supplies, the user can activate the opening motor 302 to drive the cover plate 303 to rotate. At this time, the opening at one end of the material storage rectangular box 301 can be exposed. Then, the user can use the extension rod 304 to drive the material push plate 305 to move, so as to push out the materials in the material storage rectangular box 301, achieving the ability to quickly replenish supplies.
