Description

First, the surface of the camera of the aerial vehicle 8 is cleaned by the cleaning brush 29 on the swing strip plate 15, and then the surface of the camera of the aerial vehicle 8 is wiped by the wiping cotton strip 30.

[0032] In the present invention, the pressurizing box 13 is filled with a cleaning liquid.

[0033] Working principle: In this embodiment, the present invention also provides a method for using the image correction device for aerial vehicle aerial photography measurement, including the following steps:

[0034] Step 1, first, the aerial vehicle 8 and the micro motor 11 are respectively electrically connected to the control device inside the aircraft body 1 through wires. Then, when the aircraft body 1 is started to fly and take pictures with the aerial vehicle 8, when the dual cameras of the aerial vehicle 8 encounter water vapor and dust stains during the shooting process, the operator can start the swing strip plate 15 and the pressurizing mechanism through an external control device;

[0035] Step 2, the micro motor 11 is started through an external control device to drive one of the rotating rods to reciprocate forward and backward. At this time, the micro motor 11 only drives the rotating rod to rotate half a circle reciprocally. The cooperation between the forward and backward rotating rod and the transmission belt pulley drives the other rotating rod to rotate. The synchronous rotation of the rotating rods drives the transmission gear 18 to rotate. The rotation of the transmission gear 18 drives the driven gear 19 to reciprocate forward and backward. Then, the reciprocally rotating driven gear 19 drives the swing pipe 14 to rotate and the swing strip plate 15 to perform a 180-degree swinging operation. The stains on the camera of the aerial vehicle 8 are synchronously cleaned by the reciprocally swinging swing strip plate 15. First, the surface of the camera of the aerial vehicle 8 is cleaned by the cleaning brush 29 on the swing strip plate 15, and then the surface of the camera of the aerial vehicle 8 is wiped by the wiping cotton strip 30;

[0036] Step 3: When starting the micro-motor 11 through an external control device to drive one of the rotating rods to rotate, the cooperation between the rotating rod and the transmission pulley will drive the other rotating rod to rotate. The synchronous rotation of the rotating rods facilitates driving the transmission gear 18 to rotate. The rotation of the transmission gear 18 drives the driving gear 17 to rotate. Due to the gear ratio difference between the transmission gear 18 and the driving gear 17, when the transmission gear 18 rotates half a turn, the driving gear 17 will rotate one full turn. Then, the driving gear 17 rotating forward and backward drives the hinge rod 20 and the transverse movement rod 21 to drive the dynamic sealing plate 22 inside the pressurization chamber to perform reciprocating transverse movement. The reciprocating transverse movement of the dynamic sealing plate 22 facilitates reciprocating pressurization into the pressurization box 13. The pressurization inside the pressurization box 13 facilitates pushing the sealing block 24 downward through air pressure. The downward movement of the sealing block 24 facilitates pressing the cleaning liquid inside the pressurization box 13 to enter the liquid supply chamber inside the swing strip plate 15 through the liquid supply pipe 28. Then, the pressurized cleaning liquid is sprayed on the camera lens of the aerial vehicle 8 through the atomizing nozzle 31 to improve the cleanliness of cleaning the surface of the camera of the aerial vehicle 8;

[0037] Step 4: After the cleaning of the surface of the camera of the aerial vehicle 8 is completed, after stopping driving the transmission mechanism and the pressurization mechanism, the air pressure inside the pressurization box 13 will automatically decrease, and then the sealing block 24 inside the pressurization box 13 will automatically reset and rise under the action of the return spring 27.

[0038] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
