Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle reconnaissance device with a night vision and anti-fogging function. Background Technique

[0002] Reconnaissance UAVs are used for artillery positioning and calibration reconnaissance. They are unmanned aircraft controlled by radio remote control equipment and self-contained program control devices. From a technical perspective, they can be divided into: unmanned helicopters, unmanned fixed-wing aircraft, unmanned multi-rotor aircraft, unmanned airships, unmanned parafoil aircraft, etc. The emergence of UAVs has brought great convenience to reconnaissance;

[0003] The publication number CN211167431U discloses an unmanned aerial vehicle reconnaissance device with night vision and anti-fogging functions. This device can drive a cleaning cotton to move through the telescopic movement of a hydraulic cylinder to clean the fogging part of the night vision camera. Generally, night reconnaissance takes a long time, and thus multiple cleanings are required. Some of the fog water will be adsorbed in the cleaning cotton. If the water content inside the cleaning cotton reaches saturation, its cleaning ability will decline, and the problem of incomplete cleaning next time will occur. Therefore, those skilled in the art have proposed an unmanned aerial vehicle reconnaissance device with a night vision and anti-fogging function. Content of the Utility Model

[0030] Figure 6 Cross-sectional view of a cleaning mechanism for a drone reconnaissance device with night vision and anti-fogging functions;

[0031] As Figures 1-6 As shown, a drone reconnaissance device with night vision and anti-fogging functions of the present disclosure may include: a drone main body 1, a night vision device 2, a cleaning mechanism, and a fixing mechanism;

[0032] The night vision device 2 is arranged directly below the drone main body 1. At night, the drone main body 1 can drive the night vision device 2 to fly, and night reconnaissance can be carried out through the night vision device 2.

[0033] As Figures 1-6 As shown, the cleaning mechanism includes an L-shaped seat 3, an L-shaped groove 4, a motor 5, a screw 6, a threaded seat 7, a mounting plate 8, a cleaning cotton 9, an electric push rod 10, a pressing plate 11, and a through hole 24;

[0034] The L-shaped seat 3 is installed on the lower surface of the drone main body 1 and on one side of the lens of the night vision device 2. The L-shaped groove 4 is opened on the side of the L-shaped seat 3. The motor 5 is installed on the side of the L-shaped seat 3. The screw 6 is installed at the driving end of the motor 5 extending into the L-shaped groove 4, and the end is rotatably connected to the inner wall of the L-shaped groove 4. The threaded seat 7 is arranged on the screw 6, and the side is slidably connected to the inner wall of the L-shaped groove 4. The mounting plate 8 is installed on the lower surface of the threaded seat 7 and is within the L-shaped groove 4. The cleaning cotton 9 is installed on the side of the mounting plate 8. The electric push rod 10 is installed on the rear surface of the L-shaped seat 3. The pressing plate 11 is arranged within the L-shaped groove 4 on one side of the cleaning cotton 9 and is fixedly connected to the end of the telescopic arm of the electric push rod 10 extending into the L-shaped groove 4. A plurality of through holes 24 are opened on the lower surface of the L-shaped seat 3 and communicate with the L-shaped groove 4;

[0035] When the lens surface of the night vision device 2 gets fogged up, the motor 5 operates to drive the screw 6 to rotate. The rotating screw 6 drives the threaded seat 7 to move, drives the cleaning cotton 9 to move through the mounting plate 8, and uses the moving cleaning cotton 9 to wipe off the fog and water on the lens surface of the night vision device 2 to ensure the clarity during the imaging of the night vision device 2. Then, the motor 5 drives the screw 6 to reverse to move the cleaning cotton 9 back into the L-shaped groove 4 on one side of the pressing plate 11 through the above operation. When the cleaning cotton 9 is saturated with water due to excessive cleaning, the electric push rod 10 extends to drive the pressing plate 11 to slowly move towards the mounting plate 8, and then uses the mounting plate 8 and the pressing plate 11 to slowly squeeze the cleaning cotton 9 to squeeze out the water contained in the cleaning cotton 9, realizing the cleaning of the water in the cleaning cotton 9. The squeezed water is discharged through the through hole 24 to avoid the situation where the cleaning effect of the fog and water on the lens of the night vision device 2 is not ideal due to the cleaning cotton 9 being saturated with water.

[0036] As Figures 1-6As shown in the figure, the fixing mechanism includes a fixing base 12, a card slot 13, a cavity 14, a limiting plate 15, a spring 16, a plug-in 17, a central groove 18, a rotating rod 19, a pull rope 20, a knob 21, a clamping member 22, and a slot 23;

[0037] The fixing base 12 is installed on the lower surface of the UAV body 1. Two groups of cavities 14 are opened in the fixing base 12 in a rectangular shape. Each card slot 13 is installed on the upper surface of the fixing base 12 and is located on one side of the corresponding cavity 14. Each limiting plate 15 is arranged in the corresponding cavity 14 and is slidably connected to the inner wall of the side surface. Each spring 16 is arranged in the corresponding cavity 14 and is located on one side of the limiting plate 15. Each central groove 18 is opened in the fixing base 12 and is located between a corresponding group of two cavities 14. The rotating rod 19 is rotatably installed in the two central grooves 18. Each pull rope 20 is installed at the center of the side surface of the corresponding limiting plate 15 and extends into the nearest central groove 18 to be fixedly connected to the rotating rod 19. Each clamping member 22 is arranged in the corresponding card slot 13 and is fixedly connected to the night vision device 2. Each slot 23 is opened on the side surface of the corresponding clamping member 22. Each plug-in 17 is arranged in the corresponding slot 23 to be adapted to it and the end extends into the nearest cavity 14 to be fixedly connected to the limiting plate 15. The knob 21 is installed at the end of the rotating rod 19 extending outside the fixing base 12;

[0038] When removing the night vision device 2 from the UAV body 1, only need to rotate the knob 21 to drive the rotating rod 19 to rotate, wind the four pull ropes 20, pull the four limiting plates 15 to move. While each moving limiting plate 15 compresses the spring 16, it drives the plug-in 17 to move out of the inserted clamping member 22 and into the cavity 14, releasing the fixation of the four clamping members 22. After that, the night vision device 2 and the four clamping members 22 can be removed from the fixing base 12, realizing the disassembly of the UAV body 1 and the night vision device 2. During installation, only need to rotate the knob 21 to make the four plug-ins 17 enter the cavity 14 through the above operations. Then insert the four clamping members 22 on the night vision device 2 into the four card slots 13. When fully inserted, the slot 23 on each clamping member 22 is exactly aligned with the plug-in 17. After that, loosen the knob 21 to let all the springs 16 rebound to drive each plug-in 17 to insert into the nearest aligned slot 23, re-fixing the UAV body 1 and the night vision device 2.
