[0002] With the improvement of the development of waters or sea areas in my country, the frequency of people's marine activities has gradually increased, resulting in frequent drowning accidents. The existing methods of throwing lifebuoys are all manual, which is difficult to throw accurately, and there are many areas on the water that need rescue that cannot be reached by humans, so rescue cannot be carried out in time. The use of helicopters for rescue is costly and has poor maneuverability.

[0003] With the development of science and technology, drones have begun to be used in various industries due to their advantages of low cost, high flight speed and short preparation time. In view of the need for rapid response in water rescue, drones with fast response and strong maneuverability have been widely used in water rescue.

[0004] The existing patent with announcement number CN213921429U specifically discloses a flying lifebuoy, including a lifebuoy body, on which a power supply, a flight power system and a control system are installed. The lifebuoy body mainly includes a shell and a foam float, wherein the shell is divided into an upper shell and a lower shell, and the upper shell and the lower shell are integrally formed of plastic material.

[0005] During actual use, the part of the lifebuoy body used to install the flight power system is most likely to be damaged by collision. In addition, the weight of the existing flight lifebuoy needs to be reduced. Summary of the invention

The wing portions 4 can be set to other numbers such as 2 / 4 / 6. In this embodiment, 4 wing portions 4 are taken as an example for specific description.

[0028] A connection assembly 7 is also provided between the fuselage 1 and the wing 4, wherein the wing 4 specifically includes a ring body 5 and a rotor seat 6. An upper limit edge is extended from the upper end of the upper half shell 2 facing the wing 4, and a lower limit edge is extended from the lower end of the lower half shell 3 facing the wing 4. When the ring body 5 is connected to the fuselage 1, the ring body 5 is clamped to the upper limit edge and the lower limit edge. In addition, conventional methods such as adhesives and screws can be used between the ring body 5 and the fuselage 1 to further strengthen the connection stability between the two.

[0029] The rotor seat 6 needs to be fixed inside the ring body 5. An installation cavity 61 is preset in the middle of the rotor seat 6, and four plug-in cavities 62 extend on the circumferential side of the outer periphery of the rotor seat 6. Combined with the above-mentioned connecting assembly 7, it specifically includes 4 main rods 71 ​​and 8 auxiliary rods 72. The 4 main rods 71 ​​are respectively and circumferentially evenly spaced and penetrate the fuselage part 1. Both ends of the 4 main rods 71 ​​extend into the inside of the ring body 5 from the upper side or the lower side of the ring body 5. For the sake of ease of understanding, in this embodiment, a limiting cavity 12 for penetrating and plugging the main rod 71 is preset in the upper half shell 2. Therefore, both ends of the main rod 71 extend into the ring body 5 from the upper side of the ring body 5, and the end of the main rod 71 is embedded in one of the installation cavities 61 of the rotor seat 6. Therefore, at this time, the two installation cavities 61 in each rotor seat 6 are respectively plugged and matched with the ends of the two main rods 71.

[0030] In addition, at least one sleeve seat 52 is provided on the ring body 5. In this embodiment, a double sleeve seat 52 is adopted, each sleeve seat 52 is aligned with a mounting cavity 61 of the rotor seat 6, and a secondary rod 72 is inserted and installed between the sleeve seat 52 and the mounting cavity 61, so that the main rod 71 and the secondary rod 72 cooperate to support and fix the rotor seat 6.

[0031] At the same time, a groove 53 is preset on the ring body 5, and the sleeve seat 52 can be detachably clamped in the groove 53, and lugs are extended on the sleeve seat 52 and the ring body 5, and the lugs are connected by bolts. In the actual installation process, the main rod 71, the rotor seat 6, the auxiliary rod 72 and the sleeve seat 52 are installed in sequence to avoid deformation of the main rod 71, the auxiliary rod 72 and the ring body 5, which is convenient for installation.

[0032] The above-mentioned ring body 5 is also provided with an escape opening 51, and the fuselage 1 is provided with a mounting groove 11 aligned with the escape opening 51. In addition, protective net covers 54 are installed on both upper and lower sides of the ring body 5, and the protective net covers 54 partition the internal space of the ring body 5.

[0033] In this embodiment, the main rod 71 is installed in the limiting cavity 12 of the upper half shell 2, and a power storage cavity 13 is reserved between the upper half shell 2 and the lower half shell 3 below the limiting cavity 12. A power storage shell 14 is detachably installed in the power storage cavity 13, and the opening of the power storage shell 14 is facing the horizontal direction, and a power storage cover 15 for sealing the power storage shell 14 is hingedly installed on the body 1.

[0034] The working principle of the present invention is: The split fuselage portion 1 and the wing portion 4 are connected by a main rod 71 and a secondary rod 72, avoiding the existing integrated design, making it easier to maintain and replace any of the components separately, and the main rod 71 and the secondary rod 72 can be made of lighter materials, which can effectively reduce the overall weight of the shell.

[0035] Embodiment 2

[0036] like Figure 1-4 As shown, an application embodiment is a flying life buoy with a combined shell, and the flying life buoy specifically also includes a power supply 8 that can be detachably installed in a power compartment shell 14, so that the power supply 8 can be installed and disassembled laterally, reducing the contact between the power supply 8 disassembly gap and the water sources below and above, and improving the sealing of the power supply 8 of the flying life buoy as a whole.

[0037] In addition, the motor 91 is installed on the rotor seat 6, and the propeller 92 is installed on the motor 91 to achieve stable installation of the power assembly 9 on the housing. At the same time, the electronic speed regulator 10 for controlling the output power of the power assembly 9 is installed in the installation groove 11 of the fuselage 1, and the electronic speed regulator 10 is aligned with the avoidance opening 51 on the ring body 5. During the actual flight process, the airflow is formed in the ring body 5 due to the rotation of the propeller 92, and the airflow passes through the surface of the electronic speed regulator 10 through the avoidance opening 51, so that the electronic speed regulator 10 is quickly cooled down, and the electronic speed regulator 10 can be hidden inside to avoid damage from bumps.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
