Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) technology, specifically to an aircraft. Background Technology

[0002] Aircraft are devices that can fly in a controlled manner within the Earth's atmosphere. They mainly include fixed-wing aircraft, helicopters, and drones. According to their flight principles, they are classified into aerodynamic aircraft and rocket-powered aircraft. Some experimental models use electromagnetic plasma conversion technology to achieve air energy conversion.

[0003] In field material transportation operations, drones are widely used for cargo handling and delivery due to their efficient and flexible transportation capabilities. However, due to the complex and varied terrain environment in the field, conventional drones usually need to land on flat and solid ground to complete the cargo box fixing and loading operations when performing transportation tasks. In special terrain conditions such as overgrown weeds or swamps, it is often difficult to find a stable parking area that meets the requirements, which makes it impossible for drones to successfully carry out the loading process, greatly reducing the applicability of transportation operations.

At the same time, the worm gear 303 drives the connecting rod 220 to pull the guide rope block 207 to slide back and forth along the guide slide post 206 through the eccentric rotation of the eccentric wheel 219. When the first limit waist hole 217 slides back and forth, it causes the coil end of the suspension rope 306 to move back and forth along the surface of the take-up roller 305. The suspension rope 306 is evenly unwound on the surface of the take-up roller 305. When the suspension rope 306 is unwound, the standard material transport module is lowered to the ground. Then, the material storage box 403 is opened to retrieve and place materials. After the materials are retrieved and placed, the box cover 404 is closed, and the take-up motor 302 is started. The take-up motor 302 drives the worm gear 303 to rotate in the opposite direction, thereby realizing the take-up of the suspension rope 306. When the box cover 404 rises to contact the lower surface of the connecting plate 102, the electromagnetic lock 108 is closed, and the lock tongue extends into the lock groove block 406 to form a lock. Then, the UAV body 101 is controlled to return or transport, thereby preventing the UAV body 101 from falling to the ground. When the location where the drone body 101 drops supplies cannot remain for an extended period, it needs to directly airdrop the supplies. During the airdrop, the rope-cutting motor 213 is activated, which drives the drive gear 215 to rotate. When the drive gear 215 rotates, it drives the rack frame 216, causing the sliding plate 203 to slide. When the sliding plate 203 slides, it drives the rope-cutting ring cutter 204 to cut the suspension rope 306. Then, the electromagnetic lock 108 is opened, and the electromagnetic lock 108 retracts its locking tongue. At this time, the standard supplies loading module is directly airdropped to the ground. When special personnel transportation is required, the drone body 101 is flown to hover above the designated location. Then, the electromagnetic lock 108 is opened, the electromagnetic lock 108 retracts its locking tongue, and the winding motor 302 is started to unwind the suspension rope 306. When the suspension rope 306 is unwinding, the standard material transportation module is lowered to the ground. Then, the limit handle 409 is pulled outward to release its limit on the pull cylinder 420. Then, the pull cylinder 420 is pulled inward. When the pull cylinder 420 is pulled, the locking block 416 is pulled outward and separated from the annular tooth groove 308 through the connecting column 419. Then, the four end plugs 307 are pulled out, and the special personnel transportation module is installed through the threaded connection between the threaded head 502 and the end plugs 307. Then, the special personnel sit and are fixed inside the hoisting strap 501. Then, the drone body 101 is gradually raised to lift the special personnel. Then, the drone body 101 is controlled to fly, thereby realizing the special personnel transportation.
