This significantly improves cleaning efficiency and reduces manual intervention and labor intensity. The adjustment assembly adjusts the distance between the cleaning cloth and the film, ensuring uniform and comprehensive cleaning and avoiding blind spots. This addresses the low efficiency, high labor intensity, and limited cleaning range of traditional manual cleaning.

[0068] The distance sensor 5.6 is used to detect the distance between the two ends of the long rod 4.3 and the film. The distance sensor 5.6 is fixedly connected to the bottom of the long rod 4.3 and sends a signal to the motor 5.4 through the control terminal. The motor 5.4 drives the left and right swing components 5.2 to adjust the position of the long rod 4.3 so that the cleaning cloth 5.5 is tangent to the film space, thereby expanding the cleaning range and enhancing the cleaning effect.

[0073] Example 3

[0074] This embodiment provides a method for using a greenhouse film cleaning device mounted on a drone, which is the method for using the greenhouse film cleaning device mounted on a drone provided in Example 1 or Example 2, including the following steps:

[0075] S1. Fix the cylindrical rod 3.1 of the support assembly 3 to the landing gear 1.1 at the lower end of the drone 1 using a double-ended adjustable pipe clamp, ensuring that the two cylindrical rods 3.1 are parallel; install the support rod 3.2 with the mounting hole between the two cylindrical rods 3.1, and adjust the tightness using the double-ended adjustable pipe clamp to adapt to different drone models; connect the rotating rod 4.1 of the rotating assembly 4 to the support assembly 3 via the bearing 4.6, ensuring that the rotating rod can rotate freely; put the cleaning cloth 4.5 on the long rod 4.3 using the snap 4.5.1, and choose the fiber cloth or brush material according to the degree of film contamination.

[0076] S2: Start the drone 1 and control it to fly near the greenhouse film. During flight, the airflow generated by the rotating rotor drives the fan blades 4.2 to rotate, which in turn drives the rotating rod 4.1 to rotate, causing the long rod 4.3 to rotate, which drives the cleaning cloth 4.5 to swing and contact the film surface to remove dirt.

[0077] S3, the distance measuring sensor 5.6 detects the distance between the two ends of the long rod 4.3 and the film, and sends a signal to the motor 5.4 through the control terminal. The rotating shaft 5.5 of the motor 5.4 drives the first swing rod 5.2.2 in the left and right swing assembly 5.2 to swing, and the first swing rod 5.2.2 then drives the swing arm 5.2.1 to swing, thereby driving the long rod clamp 4.4 to swing with the long rod 4.3 through the second swing rod 5.2.3, adjusting the distance between the two sides of the long rod 4.3 and the film, so that the long rod 4.3 is tangent to the film space.

[0078] S4, after the cleaning task is completed, the staff can control the drone body 1 to land on the bracket 2, and can disassemble the support component 3, the rotating component 4 and the adjusting component 5 to facilitate the drone to perform other tasks.

[0079] The present invention uses the wind force of the drone body taking off to drive the fan blades to rotate, simultaneously driving the long pole covered with a cleaning cloth to rotate, achieving the purpose of dust removal. Distance sensors installed at the lower ends of the rotating pole sense the distance between the long pole and the film, and then adjust the distance between the two ends of the long pole and the film through the adjustment assembly. After cleaning is completed, the drone body can be controlled to land on the bracket. When not performing cleaning tasks, the support assembly 3, rotating assembly 4, and adjustment assembly 5 can be disassembled to facilitate the drone to perform other tasks. The device has a simple structure, is easy to operate, can effectively remove pollutants such as dust and pollen, and has good versatility and market application prospects.
