During its actual use, defogger is first added to the defogger supply part 40 before use, and the defogger supply part 40 is controlled to deliver the defogger to the absorbent cotton 32. After the absorbent cotton 32 absorbs enough defogger, the swing arm 30 is swung back and forth left and right (the swing range is controlled to be about 60 degrees), so that the absorbent cotton 32 applies the defogger to the lens 21, avoiding fog on the surface of the lens 21 when the drone is flying for shooting, thereby ensuring the clarity of the camera.
[0031] And when the swing arm 30 drives the absorbent cotton 32 to scrape the lens 21, the stains on the surface of the lens 21 can also be cleaned to ensure the cleanliness of the lens 21 surface and avoid affecting the clarity of the shooting. After the swing is completed, the swing arm 30 is adjusted to avoid the position of the lens 21 to avoid it blocking the lens 21.
[0032] Compared with the prior art, the drone shooting device for shooting farmland images provided in this embodiment delivers defogger to the absorbent cotton 32 through the defogger feeding part 40. After the absorbent cotton 32 absorbs enough defogger, it swings the swing arm 30 back and forth to allow the absorbent cotton 32 to apply the defogger to the lens 21, thereby avoiding fogging on the surface of the lens 21 when the drone is flying and shooting, thereby ensuring the clarity of the camera.
[0033] In a possible implementation, the camera 20 is configured as follows: Figures 1 to 5 The structure shown, see Figures 1 to 5, the front side wall of the camera 20 is provided with a rotary driving part 50 above the lens 21, the rotary driving part 50 has a driving end extending to the front side, and the rotating shaft 31 is connected to the driving end of the rotary driving part 50.
[0034] Specifically, the driving of the swing arm 30 is realized by the forward and reverse rotation of the rotary driving part 50, so that the swing arm 30 drives the water-absorbing cotton 32 to repeatedly scrape the surface of the lens 21, so that the defogging agent is uniformly applied to the surface of the lens 21, and the stains on the surface of the lens 21 can also be removed, realizing the automatic application of the defogging agent on the surface of the lens 21 and the automatic cleaning of the stains on the surface of the lens 21, and improving the practicability.
[0035] In some embodiments, referring to Figures 1 to 6 , the outer peripheral wall of the rotating shaft 31 is provided with a limiting table 311 protruding outward and located at the rear side of the swing arm 30, the swing arm 30 is provided with a through hole 33 through which the rotating shaft 31 passes, the swing arm 30 is in sliding connection with the rotating shaft 31, and the outer peripheral thread of the rotating shaft 31 is provided with a nut 34 located at the front side of the swing arm 30. The nut 34 can rotate and push the swing arm 30 to abut against the limiting table 311 to lock the axial position of the swing arm 30.
[0036] Specifically, the swing arm 30 and the rotating shaft 31 are in sliding connection along the axial direction of the rotating shaft 31. When it is necessary to install the swing arm 30, the through hole 33 is aligned with the rotating shaft 31, the rotating shaft 31 passes through the through hole 33, and then the nut 34 is sleeved on the outer periphery of the rotating shaft 31. The nut 34 is rotated to push the swing arm 30 to abut against the limiting table 311, so as to realize the installation and locking of the swing arm 30.
[0037] In some embodiments, referring to Figure 4 , the outer peripheral wall of the rotating shaft 31 is provided with a positioning groove 312 extending axially to the outer end of the rotating shaft 31, and the inner peripheral wall of the through hole 33 is provided with a positioning block 331 located in the positioning groove 312.
[0038] Specifically, the positioning block 331 and the positioning groove 312 are in sliding connection. Through the cooperation of the positioning block 331 and the positioning groove 312, the swing arm 30 can only move along the axial direction of the rotating shaft 31, and the relative rotation between the swing arm 30 and the rotating shaft 31 is limited, so as to facilitate the vertical swinging of the swing arm 30 driven by the rotating shaft 31.
[0039] In some embodiments, referring to Figures 2 to 6 , the rear side wall of the swing arm 30 is provided with limiting strips 35 spaced apart along the width direction of the swing arm 30, the limiting strips 35 extend along the length direction of the swing arm 30, and the limiting strips 35 form an accommodating groove 36 for accommodating the water-absorbing cotton 32 between the two limiting strips 35. The water-absorbing cotton 32 is in abutting cooperation with the inner side wall of the accommodating groove 36, and the rear side wall of the water-absorbing cotton 32 protrudes from the rear edge of the limiting strip 35.
[0040] Specifically, the absorbent cotton 32 can be detachably installed in the accommodating groove 36. During installation, the absorbent cotton 32 can be directly inserted into the accommodating groove 36. The absorbent cotton 32 is squeezed by the inner side wall of the accommodating groove 36, so that the absorbent cotton 32 is stably installed in the accommodating groove 36, and the absorbent cotton 32 protrudes from the rear edge of the limiting strip 35, which is used to facilitate the absorbent cotton 32 to scrape the lens 21 and prevent the limiting strip 35 from scratching the lens 21.
[0041] Furthermore, it is convenient for the staff to replace the absorbent cotton 32 regularly, so as to prevent the absorbent cotton 32 from becoming too dirty and contaminating the lens 21 after long-term use.
