[0002] Marine UAVs refer to UAVs used for activities such as monitoring and discovering marine activities, or cleaning up garbage on the sea surface. Today's marine UAVs can be equipped with satellite communication equipment and optoelectronic platforms, hyperspectral cameras, lidars, high-definition CCD area array cameras, high-definition three-in-one (photo, video, infrared) payloads and other aerial remote sensing sensors and equipment. Their main technical indicators such as flight time, range, and payload capacity can meet the requirements of most marine environment monitoring tasks.

[0003] However, normally working ocean drones often lose control and crash into the sea due to signal interruption, lack of power, etc. As mentioned above, ocean drones are often equipped with many relatively expensive electronic equipment. Once an ocean drone crashes into the sea, due to cost requirements, in most cases the staff will salvage it. However, the ocean is relatively vast, so how to accurately locate the ocean drone has become a more difficult problem. Drones that crash into the sea often stop working because water enters the circuit, that is, the positioning and navigation system fails, making the task of salvaging ocean drones more difficult.

[0023] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Example 1

[0028] Reference Figures 1 to 6, which is the first embodiment of the utility model, and provides a self-rescue marine drone that falls into the sea, including a floating assembly 1, including a fuselage 11, a chassis 12, a fitting module 13, a foam board 14, an expansion module 15, and a diffusion module 16. The chassis 12 is fixedly arranged at the bottom of the fuselage 11, the fitting modules 13 are respectively arranged on the outside of the chassis 12, the foam board 14 is fixedly arranged at the bottom of the chassis 12, the foam board 14 is arranged at the bottom of the fitting module 13, the expansion module 15 is arranged at the upper end of the fuselage 11, and the diffusion module 16 is arranged at the bottom of the fitting module 13. 6 is arranged between the fitting module 13 and the chassis 12, the positioning module 2 includes a buzzer 21, a power module 22, and a moisture-proof module 23, the power module 22 is arranged on the side of the chassis 12, the buzzer 21 is arranged on the upper end of the power module 22, and the moisture-proof module 23 is arranged on the outer side of the power module 22. When the marine drone crashes unexpectedly, the expansion module 15 is opened to slow down the descent speed of the drone because the acceleration sensor 15a on the drone body detects that the descent speed of the drone reaches a critical value. When the drone falls to the sea level, the diffusion module 16 diffuses around by relying on the impact force of the drone after being slowed down, thereby increasing the contact area between the bottom of the ocean drone and the sea level, so as to cooperate with the foam board 14 to make the drone float on the sea level and not fall into the seabed. Because the airbag 15d of the ocean drone has been opened and the tilt of the drone has been corrected before the uncontrolled fall, the inclination angle of the foam board 14 at the bottom of the ocean drone and the sea level will not be too large, and the fitting module 13 is cooperated to prevent the ocean drone from having the fuselage 11 contact the sea level (that is, the side end of the ocean drone falls downward into the sea). When the ocean drone floats on the sea level, the diffusion module 16 will drive the power module 22 to be powered on during the diffusion process of the drone, so that the buzzer 21 is turned on to sound an alarm, which is convenient for the staff to find. The moisture-proof module 23 is used to prevent the power module 22 from contacting the seawater and leaking and failing. The advantage of this method is that even if the ocean drone is shut down, the buzzer 21 can still be triggered to alarm, which increases the probability of the staff finding the ocean drone.

[0029] Specifically, the fitting module 13 includes a telescopic outer rod 13a, a wing bottom plate 13b, and an inner rod 13c. The telescopic outer rod 13a is arranged at the bottom end of the fuselage 11, the inner rod 13c is slidably arranged on the inner side of the telescopic outer rod 13a, and the wing bottom plate 13b is rotatably arranged on the outer side of the bottom end of the inner rod 13c. When the ocean drone falls, the wing bottom plate 13b will contact the sea level. At the same time, the diffusion module 16 diffuses toward the outer end of the ocean drone, so that the inner rod 13c slides out from the telescopic outer rod 13a, thereby driving the wing bottom plate 13b to expand in all directions, thereby increasing the contact area between the ocean drone and the sea level, thereby cooperating with the foam board 14 at the bottom to make the ocean drone float on the sea surface.

[0030] Further, the expansion module 15 includes an acceleration sensor 15a, an ignition device 15b, a fuel device 15c, an airbag 15d, and a reaction frame 15e. The reaction frame 15e is fixedly arranged at the upper end of the fuselage 11, the ignition device 15b is fixedly arranged inside the reaction frame 15e, the fuel device 15c is fixedly arranged inside the reaction frame 15e, the airbag 15d is arranged at the upper end of the reaction frame 15e, the acceleration sensor 15a is arranged at the upper end of the fuselage 11, and the acceleration sensor 15a is arranged outside the reaction frame 15e. The diffusion module 16 includes a body bottom plate 16a, a spring 16b, a magnet 16c, a magnet 16d, and a side frame 16e. The magnet 16d is fixedly arranged on the chassis 1 2 bottom end, spring 16b is fixedly arranged on the outer side around magnet 16d, body bottom plate 16a is fixedly arranged on the lower end of spring 16b, magnet 16c is fixedly arranged on the upper end of body bottom plate 16a, side frame 16e is fixedly arranged on the bottom end of chassis 12, body bottom plate 16a is slidably arranged on the inner side of side frame 16e, diffusion module 16 comprises connecting column 16f, loose leaf 16g, wing bottom rod 16h, connecting platform 16i, wing bottom rod 16h is respectively fixedly arranged on the bottom end of fuselage 1, loose leaf 16g ​​is flipped and arranged on the bottom end of wing bottom rod 16h, telescopic outer rod 13a is fixedly arranged on the bottom end of loose leaf 16g, connecting platform 16i is fixedly arranged on the upper end of wing bottom plate 13b, inner rod 1 3c is rotatably arranged on the inner side of the upper end of the connecting platform 16i, and the connecting column 16f is rotatably arranged between the bottom plate 16a of the body and the inner rod 13c. When the marine drone falls in time and space, its acceleration increases sharply. The acceleration sensor 15a detects that the acceleration of the marine drone reaches a predetermined value, and then starts the ignition device 15b through the control panel of the drone. The ignition device 15b reacts with the fuel device 15c to generate a large amount of expansion gas to expand the airbag 15d to form a parachute, thereby slowing down the descent speed of the marine drone and correcting the angle of the marine drone when it descends to prevent the side end of the marine drone from facing downward when it contacts the sea level. When the foam board 14 at the bottom of the marine drone When it touches the sea level, the impact force mitigated by the airbag 15d squeezes the body bottom plate 16a upward, and at the same time, the spring 16b accumulates force, and the body bottom plate 16a moves toward the upper end along the side frame 16e, and then the magnet 16c and the magnet 16d attract each other, so that the body bottom plate 16a rises to a certain position. When the body bottom plate 16a rises to a certain position, the connecting column 16f pushes the inner rod 13c to slide outward, and at the same time, the wing bottom plate 13b connected to the bottom end of the inner rod 13c and the foam board 14 at the bottom end are always vertically downward due to the rotation cooperation between the inner rod 13c and the connecting platform 16i. Finally, the contact area between the ocean drone and the sea surface becomes larger, and the ocean drone is able to float on the sea surface.

[0031] Example 2

[0032] Reference Figures 1 to 6As shown, it is the second embodiment of the utility model, which is different from the previous embodiment in that: the power-on module 22 includes a connecting wire 22a, a battery block 22b, a connecting block 22c, and a connecting column 22d. The connecting block 22c is fixedly arranged at the side end of the chassis 12, the battery block 22b is arranged at the bottom end of the connecting block 22c, the connecting wire 22a is electrically connected to the bottom end of the buzzer 21, the buzzer 21 is fixedly arranged at the upper end of the connecting block 22c, and the connecting column 22d is fixedly arranged between the battery block 22b and the body bottom plate 16a. When the marine drone descends to the sea surface, as the body bottom plate 16a rises, it drives the battery block 22b to move to the upper end through the connecting column 22d, so that the battery block 22b contacts the connecting wire 22a, so that the buzzer 21 can be powered on and an alarm sound is issued to facilitate the staff to find it.

[0033] Furthermore, the moisture-proof module 23 includes a sponge opening block 23a, a mounting shell 23b and a slide groove 23c. The mounting shell 23b is fixedly arranged at the bottom end of the connecting block 22c, the slide groove 23c is opened inside the mounting shell 23b, the sponge opening block 23a is installed on the side of the mounting shell 23b, and the sponge opening block 23a is arranged on the outside of the connecting column 22d. In order to prevent the battery block 22b from getting damp and being unable to accurately shift to contact the connecting wire 22a, the battery block 22b is slidably arranged in the mounting shell 23b, and slide grooves 23c are opened on both sides of the mounting shell 23b to straighten the movement of the battery block 22b. At the same time, the sponge opening block 23a is arranged at the connecting column 22d to prevent the upper end of the battery block 22b from contacting sea water.

[0034] The working principle of the utility model is as follows: when the marine drone crashes unexpectedly, its acceleration increases sharply, and the acceleration sensor 15a detects that the acceleration of the marine drone reaches a predetermined value, and then the ignition device 15b is started through the control panel of the drone, and the ignition device 15b reacts with the fuel device 15c to generate a large amount of expanding gas to open the airbag 15d to form a parachute, thereby slowing down the descent speed of the marine drone and straightening the angle of the marine drone during descent to prevent the side end of the marine drone from facing downward when it contacts the sea level. When the foam board 14 at the bottom of the marine drone contacts the sea level, the impact force mitigated by the airbag 15d squeezes the body bottom plate 16a upward, and at the same time the spring 16b accumulates force, and the body bottom plate 16a moves upward along the side frame 16e, and then the magnetic The stone 16c and the magnet 16d attract each other, so that the body bottom plate 16a rises to a certain position. When the body bottom plate 16a rises to a certain position, the connecting column 16f pushes the inner rod 13c to slide outward. At the same time, the wing bottom plate 13b connected to the bottom end of the inner rod 13c and the foam board 14 at the bottom end are always vertically downward due to the rotation cooperation between the inner rod 13c and the connecting platform 16i. Finally, the contact area between the ocean drone and the sea surface becomes larger, and the ocean drone can float on the sea surface. When the ocean drone descends to the sea surface, as the body bottom plate 16a rises, it drives the battery block 22b to move to the upper end through the connecting column 22d, so that the battery block 22b contacts the connecting wire 22a, so that the buzzer 21 can be powered on and an alarm sound is issued to facilitate the staff to find it.

[0035] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
