[0033] The embodiment provides a kind of offshore unmanned aerial vehicle device, which can avoid sinking into water after falling into water, and has good stability and compact structure.

[0034] Specifically as Figures 1 to 7As shown, the marine unmanned aerial vehicle (UAV) device includes a UAV body 100 and multiple buoyancy components 200. Exemplarily, the number of buoyancy components 200 can be two, three, or five, etc. In this embodiment, the number of buoyancy components 200 is four. The multiple buoyancy components 200 are all fixed to the outer wall of the UAV body 100 and are evenly spaced along the circumference of the outer wall of the UAV body 100. In this embodiment, the UAV body 100 is cylindrical. Each buoyancy component 200 includes an arc-shaped float 210 and multiple floating rings 220. Exemplarily, the number of floating rings 220 can be two, three, four, or six, etc., depending on the weight requirements of the UAV body 100. The arc-shaped surface of the arc-shaped float 210 is parallel to the outer wall of the UAV body 100, and the multiple floating rings 220 are stacked vertically in a manner similar to a fishing float. The arc-shaped float 210 and the floating rings 220 can float in the water.

[0035] Based on the above design, the buoyancy components 200 are all fixed to the outer wall of the UAV body 100 and are evenly spaced along the circumference of the outer wall. Compared with the bottom of the UAV body 100, this arrangement can prevent the UAV from tilting and capsizing into the water, thus improving the stability of the UAV in the water. Each buoyancy component 200 includes an arc-shaped float 210 and multiple floating rings 220. The arc-shaped float 210 and the floating rings 220 can float in the water, increasing the buoyancy of the UAV and preventing it from sinking. The arc-shaped surface of the arc-shaped float 210 is parallel to the outer wall of the UAV body 100, that is, the arc-shaped float 210 is coaxially arranged with the UAV body 100, making the structure of the UAV compact. The multiple floating rings 220 are stacked vertically, similar to a fishing float, increasing the drainage volume of the buoyancy component 200, thereby increasing the buoyancy of the buoyancy component 200 and further preventing the UAV from sinking into the water.

[0036] like Figure 4 As shown, in order to position multiple floating rings 220 and improve the stability of the marine unmanned aerial vehicle device after it falls into the water, the buoyancy component 200 also includes a positioning rod 230, and the floating rings 220 are sleeved on the positioning rod 230.

[0037] It should be noted that the positioning rod 230 is set vertically, with its two ends connected to the top and bottom of the drone body 100, respectively.

[0038] To further improve the stability of the maritime unmanned aerial vehicle (UAV) device after it lands in the water, the positioning rod 230 is located at the middle of the arc length direction of the arc-shaped float 210.

[0039] Further, the side of the arc-shaped floating plate 210 away from the UAV body 100 is provided with a avoiding groove 211, and at least part of the positioning rod 230 and the floating ring 220 are located in the avoiding groove 211, which can not only reduce the weight of the arc-shaped floating plate 210, but also reduce the occupied space of the arc-shaped floating plate 210 to make room for the floating ring 220, so that the buoyancy assembly 200 is compact in structure.

[0040] As shown in Figures 3 to 6 Further, in order to fix the arc-shaped floating plate 210 and the positioning rod 230, the marine UAV device further comprises a plurality of installation boxes 300, the installation box 300 corresponds to the buoyancy assembly 200 one by one, the inner cavity of the installation box 300 is matched with the shape of the arc-shaped floating plate 210, the arc-shaped floating plate 210 is located in the inner cavity of the installation box 300, and the two ends of the positioning rod 230 are connected with the inner top wall and the inner bottom wall of the installation box 300 respectively; the side of the installation box 300 away from the UAV body 100 is provided with a first avoiding port 310, and the first avoiding port 310 is opposite to the avoiding groove 211 to avoid the floating ring 220. The installation box 300 limits the arc-shaped floating plate 210 in the inner cavity, the fixing effect of the arc-shaped floating plate 210 is good and the installation is simple; the installation box 300 also fixes the positioning rod 230 to the inner cavity, and the floating ring 220 is also well limited; and the installation box 300 is provided with the first avoiding port 310, which can not only avoid the floating ring 220, but also make the installation box 300 open, so that water can enter the installation box 300 to make the buoyancy assembly 200 play a floating role.

[0041] It should be pointed out that the installation box 300 is an arc-shaped box, and a gap is left between the inner wall of the installation box 300 and the arc-shaped floating plate 210, that is, the arc-shaped floating plate 210 can slightly shake in the inner cavity of the installation box 300. If the stacking height of the floating ring 220 is less than the length of the positioning rod 230, that is, when the marine UAV device is not fallen into water, a gap is left between the topmost floating ring 220 and the inner top wall of the installation box 300, the floating ring 220 can slide vertically upward along the positioning rod 230.

[0042] In the embodiment, in order to increase the length of the positioning rod 230 and make more floating rings 220 be sleeved on the positioning rod 230, the inner top wall and the inner bottom wall of the installation box 300 are provided with slots, and the opposite ends of the slots are respectively penetrated with the first avoiding port 310 and the second avoiding port, which is also more convenient for water to enter the installation box 300.

[0043] In order to further facilitate water to enter the installation box 300, the bottom of the installation box 300 is provided with a plurality of water holes 320, and the number of the water holes 320 can be two, three, five or eight, etc.

[0044] In the embodiment, the plurality of circular water holes 320 are distributed on the bottom of the installation box 300. Of course, the water holes 320 can also be triangular, elliptical or square, etc.

[0045] Similarly, the mounting box 300 is provided with two sets of water channels 330 on the side away from the drone body 100. The two sets of water channels 330 are located on both sides of the first clearance opening 310 along the arc length of the arc-shaped float 210. This can reduce the weight of the mounting box 300 and facilitate water to enter the mounting box 300 so that the buoyancy component 200 can play a floating role.

[0046] Furthermore, the water channel 330 extends along the arc length of the arc-shaped float 210 and is connected to the first clearance opening 310, making it easier for water to enter the installation box 300.

[0047] In this embodiment, the first clearance opening 310 has multiple water passages 330 distributed on both sides along the arc length direction of the arc-shaped float 210, and the multiple water passages 330 are evenly spaced along the vertical direction.

[0048] Similarly, the mounting box 300 has a second clearance opening on the side surface facing the drone body 100, and the second clearance opening is directly opposite to the first clearance opening 310.

[0049] To facilitate the installation of the buoyancy component 200, the top of the mounting box 300 is provided with an opening, and a cover plate 340 is provided at the opening. The buoyancy component 200 is placed into the inner cavity of the mounting box 300, and the cover plate 340 is closed to complete the assembly and installation of the buoyancy component 200.

[0050] Furthermore, such as Figure 3 As shown, the marine unmanned aerial vehicle (UAV) device also includes a fixing component, which includes a first fixing plate 410 and a second fixing plate 420. The first fixing plate 410 is connected to the bottom of the UAV body 100 and the bottom of the mounting box 300, and the second fixing plate 420 is connected to the top of the UAV body 100 and the cover plate 340.

[0051] In this embodiment, the height of the cover plate 340 is higher than the height of the drone body 100, so the second fixing piece 420 is connected to the top of the drone body 100 and the outer wall of the cover plate 340.

[0052] Continue as Figure 1 and Figure 2As shown, the offshore unmanned aerial vehicle device further comprises a parachute 500, two detectors 600 and an auxiliary assembly, and the parachute 500, the detectors 600 and the auxiliary assembly are all located at the top of the unmanned aerial vehicle body 100. The detectors 600 can judge the flight condition of the unmanned aerial vehicle body 100, and if the falling is detected, the parachute 500 can realize the deceleration process to avoid the impact damage caused by the excessive falling speed and intensity; and the detector 600 is provided with an alarm lamp, which flashes to alarm when the unmanned aerial vehicle body 100 fails, and the frequency flash of the alarm lamp sends a warning prompt to people. The auxiliary assembly comprises a GPS locator 710 and a wireless transmitter 720, which can make the wireless transmitter 720 obtain the current approximate position through the GPS locator 710 and send it to the user when the unmanned aerial vehicle body 100 crashes, help the user quickly locate the place where the unmanned aerial vehicle body 100 crashes, and accurately and quickly develop a remedial action.

[0053] In this embodiment, the parachute 500 is located at the top center position of the unmanned aerial vehicle body 100, and the two detectors 600, the GPS locator 710 and the wireless transmitter 720 are arranged along the outer periphery of the parachute 500.

[0054] As shown in the figure, Figure 7 The unmanned aerial vehicle body 100 is also equipped with a shooting assembly, which comprises a bracket 810 and a camera 820, the bracket 810 is installed at the bottom of the unmanned aerial vehicle body 100, and the camera 820 is installed on the bracket 810.

[0055] The following is the protection process of the offshore unmanned aerial vehicle device when it crashes into water:

[0056] When the unmanned aerial vehicle body 100 is affected by various conditions and falls into water, first, the detector 600 judges the flight condition of the unmanned aerial vehicle body 100 to determine that the parachute 500 is opened to slow down when it is about to fall; then, after the unmanned aerial vehicle body 100 falls into water, the arc-shaped floating plate 210 and the plurality of floating rings 220 arranged in the installation box 300 can make the unmanned aerial vehicle body 100 float on the water surface when it falls into water, and will not sink to the bottom of the water to cause damage; finally, through the auxiliary assembly, when the unmanned aerial vehicle body 100 crashes, the wireless transmitter 720 obtains the current approximate position through the GPS locator 710 and sends it to the user, helping the user quickly locate the place where the unmanned aerial vehicle crashes, and accurately and quickly develop a remedial action.

[0057] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, various obvious changes, re-adjustments and replacements can be made without departing from the protection scope of the present application.
