Description

Technical Field

[0001] The invention relates to the technical field of unmanned aerial vehicles, and in particular to an amphibious rescue unmanned aerial vehicle. Background Art

[0002] With the rapid development of drone-related technologies, the development of drones in various fields has been promoted, especially in aerial search, rescue, detection and exploration. At the same time, my country's development of waters and seas has become increasingly high, and people's various activities in inland rivers and offshore waters have gradually increased, which has also led to frequent drowning accidents. Ordinary swimming rings are generally thrown to the rescued person, but it is difficult to accurately reach the rescued surroundings. There are now some aircraft that combine quad-rotor drones with swimming rings, which can enable the swimming ring to quickly reach the surroundings of the drowning person, but affected by air and water flow, the accuracy of the landing location of this swimming ring is not necessarily very high. Patent No. 202221933359.0 proposes an electric flying lifebuoy, which installs the four motors and propellers of the quad-rotor around the swimming ring. Although it can quickly reach the surroundings of the drowning person, if the landing accuracy is not high, it is easy to wash away the lifebuoy if it lands in a river basin with relatively turbulent water flow; although it can take off and land twice on the water surface, it also delays precious rescue time.

[0003] If the drone can move on the water surface, the rescue efficiency will be greatly improved. The water-air amphibious drone has the characteristics of both drones and unmanned boats. It can overcome the influence of air and water flow. After the amphibious drone lands around the rescued person, it can move to the rescued person on the water surface, so that the water-air amphibious drone will have a better effect on water surface rescue. Patent No. 202120090989.5 proposes a water-air amphibious life-saving stretcher that can fly quickly to the rescued person and provide buoyancy, but the two middle handles that provide rescue are difficult for children to grab at the same time. If the handle on the head is grabbed, it will block the camera's line of sight, so there may be hidden dangers in the rescue effect.

[0004] At present, although there are many types of amphibious rescue drones, due to unreasonable design, there are problems such as low efficiency in air or water navigation; difficult to grasp the rescue equipment; the equipment is not waterproof, and it is easy for water to enter the equipment when sailing on the water, causing malfunctions, etc., which makes the rescue process have safety hazards.

[0037] The outer foam ring is made of hard foam plastic, such as a density of 45Kg / m 3 or 60Kg / m 3 EPP (expanded polypropylene) material. The intermediate cabin 3, flight control cabin 2, power connecting rod 501 and other parts that do not need to be powered are made of hard plastic or carbon fiber. These materials must ensure the strength of the parts after installation and during actual flight or navigation to avoid deformation; at the same time, each installation position on the foam outer ring is bonded to the corresponding parts by strong glue. Figure 1 The overall structure diagram of an amphibious rescue drone is shown in FIG. A amphibious rescue drone has two different power systems, namely an air power system and a surface navigation power system. The air power system includes an air power part 5, which enables the entire system to fly quickly in the air; the surface navigation power system includes an underwater motor 4 and an underwater motor electric regulator 307, which enables the entire system to freely navigate on the water surface.

[0038] Before using the present invention to rescue a drowning person, first install the waterproof pan-tilt camera 201 on the front end of the upper surface of the middle cabin cover 301, adjust the angle of the camera inside the waterproof pan-tilt camera 201, and turn on the remote control to see the picture transmitted by the water pan-tilt camera 201. When it is necessary to implement rescue, first operate the air power system to reach the vicinity of the rescued person; then move to the rescued person's side through the surface navigation power system; before flying, use the light switch 320 to turn on the long light strip 321 and the buzzer 322. Among them, the buzzer 322 will also emit a buzzing sound when it is on. The buzzer 322 is between the two rescue handles 101, which is convenient for the rescued person to quickly find the rescue handle 101 and grab the rescue handle 101.

[0039] Because it needs to sail on the water, a layer of waterproof glue should be applied to the surface of the aerial motor ESC 502 and the motor wiring port. Fig.11As shown, the flight control 202 is installed in the waterproof cabin 204, and the upper surface of the waterproof cabin 204 has a groove for placing waterproof rubber; after the waterproof cabin cover 206 is tightened by screws, the lower surface of the waterproof cabin cover 206 is closely adjacent to the upper surface of the waterproof cabin 204, and waterproof rubber is provided between the two. The external signal line and power line of the flight control 202 reach the middle cabin 3 through the waterproof cabin channel 2061, and a soft air pipe is used to connect the middle cabin 3 and the flight control cabin 2 through the waterproof cabin channel 2061, so that the air pressure between the two is balanced. The side of the middle cabin 3 is well waterproofed, and there are some small gaps between the middle cabin cover 301 and the battery cover 303, so that the air pressure of the middle cabin 3 is consistent with that of the outside; when moving on the water surface, as long as the water surface does not exceed the upper surface of the foam outer ring 1, there will generally be no large amount of water on the upper surface of the middle cabin cover 301.

[0040] like Fig.12 and Fig.13 As shown, when the battery 302 needs to be replaced, the battery 302 can be taken out and replaced by pulling the pull ring on the upper surface of the battery cover 303 through the opening in the middle of the middle compartment cover 301; the battery separator 306 has a protruding part for fixing the battery 302 and the receiver 305, which can fix the battery 302 and the receiver 305 to prevent them from shaking. The receiver 305 can transmit the images and flight status received by the waterproof pan-tilt camera 201 to the remote controller, and at the same time, the operator controls its movement status by controlling the push rod of the remote controller.

[0041] The present invention not only has the function of water rescue, but also has the function of water surface monitoring. Figure 6 As shown in (b), when the waterproof pan-tilt camera 201 is installed on the camera mounting plate 203, the angle of the camera inside the waterproof pan-tilt camera 201 is adjusted so that the angle of its lens faces the water surface, and the water surface is observed and monitored by flying over the water surface through the air power system.
