It has significant advantages in rapidly acquiring high-resolution images of small areas and regions with difficult flight conditions. With the development of UAV and digital camera technologies, digital aerial photography technology based on UAV platforms has demonstrated its unique advantages. The combination of UAVs and aerial photogrammetry has made "UAV digital low-altitude remote sensing" a new development direction in the field of aerial remote sensing. UAV aerial photography has broad prospects in basic surveying and mapping, land resource investigation and monitoring, dynamic land use detection, digital city construction, and emergency disaster relief mapping data acquisition.

[0003] During the flight of aerial survey drones, the mounted cameras are exposed. When the measurement environment is complex, the camera lenses lack protective mechanisms and are easily contaminated with dust and impurities or come into contact with external objects such as tree branches, causing lens damage and affecting the aerial survey. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that during the flight of an aerial surveying drone, the mounted camera is exposed and the lens lacks a protective mechanism when the measurement environment is complex. The lens is easily contaminated with dust and impurities or comes into contact with external objects such as tree branches, causing lens damage and affecting aerial surveying. Therefore, this utility model proposes an aerial surveying device for surveying drones.

[0005] To achieve the above objectives, the present invention employs the following technology: a surveying drone aerial surveying device, comprising a body, the body including the drone body, and a shooting mechanism mounted on the bottom of the drone body by bolts;

A soft pad is provided on the other side of the clamping plate.

[0011] As a further description of the above technical solution: support frames are fixedly connected to both sides of the drone body.

[0012] As a further description of the above technical solution: the bottom of the support frame is fitted with an anti-slip sleeve, and the outer surface of the anti-slip sleeve is provided with anti-slip texture.

[0013] As a further description of the above technical solution: the shield is located directly in front of the camera, and the back of the shield is in close contact with the outer side of the camera lens.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0015] By incorporating protective and cleaning components, a shield covers the camera lens during flight, preventing dust, branches, and other objects from contacting the lens and reducing the likelihood of damage. This protects the lens. Simultaneously, the first motor drives a gear to rotate, which in turn moves a gear plate laterally. This movement of the gear plate moves a moving plate and a cleaning wiper, cleaning dust and other debris from the outer surface of the shield and preventing them from affecting the camera's shooting performance.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-4 The present embodiment provides a UAV aerial surveying device for surveying, including a body 1, which includes a UAV body 11, and a shooting mechanism 5 is bolted to the bottom of the UAV body 11.

[0024] The protective component 2 includes a frame 21, a shield 22 connected to the top of the front of the frame 21, through holes 23 on the bottom of both sides of the frame 21, and a guide groove 24 on one side of the inner bottom wall of the frame 21. The shield 22 is made of transparent plate.

[0025] The cleaning component 3 includes a first motor 31 installed at the bottom of the frame 21. The output end of the first motor 31 is connected to a gear 32. The gear 32 meshes with a toothed plate 33. A movable plate 34 is fixedly connected to the center of the front of the toothed plate 33. A cleaning wipe 35 is installed on one side of the movable plate 34. The bottom of the toothed plate 33 is slidably connected in the guide groove 24.

[0026] First, the threaded rods 6 on both sides of the sleeve frame 21 are rotated to move the clamping plates 7. The clamping plates 7 on both sides clamp the camera 53, and the sleeve frame 21 is installed on the camera 53. Then, during installation, the shielding plate 22 is pressed tightly against the lens of the camera 53. The shielding plate 22 covers the lens of the camera 53, and during flight, it blocks some dust, branches and other objects from contacting the lens, reducing the chance of lens damage and thus protecting the lens. At the same time, the first motor 31 drives the gear 32 to rotate. The rotation of the gear 32 drives the toothed plate 33 to move laterally left and right. When the toothed plate 33 moves left and right, it drives the moving plate 34 and the cleaning wipe 35 to move, thereby cleaning the dust and other debris on the outer surface of the shielding plate 22.

[0027] Specifically, such as Figure 2 and Figure 4 As shown, the bottom of the toothed plate 33 is fixedly connected to a guide plate 4 that is compatible with the guide groove 24, so both ends of the toothed plate 33 can pass through the through hole 23.

[0028] The toothed plate 33 is limited and guided by the guide plate 4 to prevent it from detaching from the sleeve 21 during movement.

[0029] Specifically, such as Figure 1 and Figure 4 As shown, the shooting mechanism 5 includes a mounting frame 51. A second motor 52 is fixedly connected to one side of the mounting frame 51. A camera 53 is connected to the output end of the second motor 52. The other side of the camera 53 is rotatably connected to one side of the inner wall of the mounting frame 51.

[0030] The second motor 52 starts, and its output drives the camera 53 to rotate, thereby adjusting the shooting angle of the camera 53.

[0031] Specifically, such as Figure 1 and Figure 2 As shown, threaded rods 6 are threaded through both sides of the sleeve frame 21, and the other end of the threaded rods 6 is rotatably connected to a clamping plate 7 via a mounting bearing. A soft pad is provided on the other side of the clamping plate 7.

[0032] The rotating threaded rods 6 on both sides drive the clamping plates 7 to move, clamping the camera 53 on both sides and installing the frame 21 onto the camera 53. The soft pads prevent the clamping plates 7 from clamping too tightly and causing damage to the camera 53.

[0033] Specifically, such as Figure 4 As shown, support frames 12 are fixedly connected to both sides of the drone body 11, and the other side of the cleaning wipe 35 is in contact with the outer surface of the shield 22.

[0034] The cleaning wipe 35 is in close contact with the baffle plate 22, and the cleaning wipe 35 moves to clean the outer surface of the baffle plate 22.

[0035] Specifically, such as Figure 1 As shown, the bottom of the support frame 12 is fitted with an anti-slip sleeve 8, and the outer surface of the anti-slip sleeve 8 is provided with anti-slip texture.

[0036] Specifically, such as Figure 1 As shown, the shield 22 is located directly in front of the camera 53, and the back of the shield 22 is in close contact with the outer side of the lens of the camera 53.

[0037] The shield 22 fits tightly against the lens of the camera 53 to prevent dust from entering through the gaps and reduce the impact of dust on the lens.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
