Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, and more particularly to a high-rise fire-fighting unmanned aerial vehicle with strong stability. Background Art

[0002] With the continuous advancement of science and technology, high-rise buildings are becoming increasingly common. Although a series of fire prevention standards and requirements have been formulated, including the fire protection standards for high-rise civil buildings, the fire problem in high-rise buildings has not been completely solved. In fact, compared with low-rise buildings, fire fighting in high-rise buildings is more dangerous and more difficult. Therefore, how to quickly and effectively extinguish fires in high-rise buildings and reduce casualties and economic losses remains a major challenge that the fire department needs to solve. In recent years, the shortage of firefighting equipment and the increase in casualties caused by close handling of explosive items during firefighting have not been fundamentally solved. At present, firefighting technology mainly relies on water spraying by fire trucks, but this method cannot fully cope with the complexity of high-rise building fires.

[0003] As disclosed in the publication number CN209441645U, the utility model relates to a large-load fire-fighting drone, comprising a mounting frame, the mounting frame comprising an upper polygonal frame and a lower polygonal frame with the same number of sides; longitudinal vertical poles are fixed at each corner of the lower polygonal frame, and the upper ends of multiple vertical poles are respectively fixedly connected to the middle position of one side of the upper polygonal frame; rotors are installed at the corners of the upper polygonal frame; a mounting plate is provided in the internal area of ​​the upper polygonal frame, and the mounting plate is fixedly connected to the upper polygonal frame and / or the vertical poles through multiple connecting rods; a power supply box for powering the rotor and a controller for controlling the rotor are provided on the mounting plate; fire-fighting equipment is provided in the area surrounded by multiple vertical poles; a fixing frame for installing the fire-fighting equipment is provided on the lower polygonal frame; not only does the mounting frame have high strength and stability, but it also has sufficient installation space for installing the drone controller, power supply box, and carrying the fire-fighting equipment, and the overall layout is compact and the overall volume is reduced, so that the fire-fighting equipment can be brought closer to the fire point.

[0004] At present, civil drones widely use batteries as their main power source, but this reliance also brings some problems. Due to the limited energy density and capacity of batteries, the endurance of drones is subject to certain restrictions, making it difficult to meet the needs of long-term and high-intensity operations, especially in some specific application scenarios, such as firefighting and rescue. The performance of drones is subject to more stringent tests. When performing firefighting tasks, drones need to carry enough water, but due to the limitation of maximum take-off weight, the amount of water they can carry is very limited, which means that once the drones have finished spraying water, they must return to the base for resupply, and this resupply process often takes a long time.

At the same time, the drone 1 can fly above the high-rise fire, so that the water spray head 5 can be rotated, and then the spray angle of the water spray head 5 can be adjusted, thereby avoiding the water spray head 5 can only perform fixed spraying when in use, resulting in a limited spraying range of the water spray head 5, thereby improving the efficiency of high-rise fire fighting.

[0036] Working principle of the present invention:

[0037] First, by placing the sprinkler head 5 on the top of the adjustment structure 8, placing the wire 3 and the water pipe 6 on the side where the two clamping plates 74 are close to each other, and then starting the electric push rod 412 to make the connecting block 413 descend, the connecting block 413 drives the connecting plate 1 414 to move while descending, and the connecting plate 1 414 drives the connecting plate 2 415 and the connecting plate 3 416 to rotate while moving, and the connecting plate 3 416 drives the mounting plate 2 421 to descend while rotating, and the mounting plate 2 421 slides on the outer wall of the slide rod 423 through the circular movable hole 1 while descending, and then drives the limit plate 1 432 and the clamping block 1 through the descending of the mounting plate 2 421 431 is lowered until the clamping block 1 431 contacts the outer wall of the water spray head 5, thereby fixing the water spray head 5 through the clamping block 1 431 and the adjusting structure 8. At the same time, the mounting plate 2 421 is lowered to push the connecting plate 443 to move the clamping plate 1 441, thereby driving the convex block 442 to slide on the inner wall of the dovetail groove 73, until the two clamping plates 1 441 are away from each other and contact the outer walls of the wire 3 and the water pipe 6 respectively. At this time, the water spray head 5, the wire 3 and the water pipe 6 are all fixed, avoiding the water spray head 5, the wire 3 and the water pipe 6 from shaking when in use, thereby improving the stability of the water spray head 5, the wire 3 and the water pipe 6 when in use;

[0038] After the sprinkler head 5 is fixed by the clamp block 2 81 and the clamp block 1 431, the rotating shaft 86 is rotated by starting the stepper motor 85, thereby driving the gear 87 to rotate. The gear 87 rotates while driving the toothed disc 83 to rotate. The toothed disc 83 rotates while driving the limit plate 2 82 to rotate on the inner wall of the circular through hole 2 72 and the clamp block 2 81 to rotate, thereby driving the sprinkler head 5 to rotate through the clamp block 2 81 and the clamp block 1 431, and driving the limit plate 1 432 to rotate on the inner wall of the circular through hole 1 422 through the rotation of the clamp block 1 431 until the sprinkler head 5 is adjusted to a suitable position. At this time, the position adjustment of the sprinkler head 5 is completed, and the sprinkler head 5 can be started to extinguish the high-rise fire. At the same time, the drone 1 can fly above the high-rise fire, so that the sprinkler head 5 can rotate, and then the spray angle of the sprinkler head 5 is adjusted, thereby avoiding the sprinkler head 5 can only be fixed sprayed when in use, resulting in a limited spray range of the sprinkler head 5, thereby improving the efficiency of high-rise fire fighting.
