Description

Technical Field

[0001] The utility model belongs to the technical field of unmanned aerial vehicle (UAV) protection devices, and in particular relates to a geological surveying and mapping UAV with a protection structure. Background Art

[0002] With the rapid development of drone technology, drones are increasingly being used across various industries. In geological mapping, drones can efficiently cover large areas, especially in areas with limited access. Their high-resolution mapping cameras can capture clear ground images to identify subtle geological features. Their low-altitude flight and multi-angle shooting modes capture clearer geological details and generate intuitive 3D models. Furthermore, they are safe and convenient, reducing risks for personnel in hazardous geological environments and are easy to carry, operate, and deploy quickly.

[0003] However, during geological surveying, drones can easily collide with foreign objects if they are not careful, causing damage. To address this, drones are being equipped with protective mechanisms. For example, the Chinese utility model patent (CN218537099U) includes a transparent protective cover installed on the surveying camera to prevent direct collisions between the camera and foreign objects, improving camera protection. A protective net is installed on the arm to protect the propeller, preventing branches from colliding with the propeller during low-altitude flight and causing damage, improving propeller protection. Anti-collision plates are installed at the ends of the arms. When the drone is accidentally collided, multiple anti-collision side plates and rubber pads can protect the drone, providing better anti-collision capabilities and preventing damage to the drone due to collisions. The buffer damper on the support plate provides a cushioning effect during landing, improving protection for the drone.

[0004] Although the patent provides a protective device for the propeller, there is still room for improvement. For example, a ring-shaped protective net is provided on the outside of the propeller, but the upper and lower parts of the propeller are not protected. There is still a risk of damage from collision with foreign objects. The protective plate and rubber pad have limited ability to absorb impact. Therefore, we propose a geological surveying drone with a protective structure. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] Reference Figures 1-4 A geological surveying drone with a protective structure includes a drone body 100, a surveying camera 200 and a landing gear 103 are provided at the bottom of the drone body 100, cantilevers 101 are provided around the drone body 100, a propeller 102 is provided near the end of the cantilever 101, and a protective mechanism 300 is provided at the propeller 102. The protective mechanism 300 is used to protect the propeller 102 and prevent the propeller 102 from being damaged by collision with foreign objects during the drone flight surveying process.

[0027] Specifically, the propeller 102 includes a rotating shaft 110 and blades 109. One end of the rotating shaft 110 is rotatably connected to the cantilever 101. Multiple blades 109 are circumferentially arranged around the rotating shaft 110. The blades 109 are close to the other end of the rotating shaft 110, so that there is a certain distance between the blades 109 and the cantilever 101. The protection mechanism 300 includes an annular protection plate 301, which is wound around the outside of the propeller 102. The annular protection plate 301 is provided with ventilation holes 302, which are in a long strip structure and are evenly spaced along the circumference of the annular protection plate 301. A support sleeve 304 is provided in the center of the upper end face and the lower end face of the annular protection plate 301 respectively. A first support rod 305 is provided between the support sleeve 304 and the annular protection plate 301, which is conducive to improving the overall structural strength of the annular protection plate 301. The cantilever 101 is located on the outside of the bottom of the rotating shaft 110 of the propeller 102 and is wound around an annular support sleeve 310. The support sleeve 304 located on the lower end face of the annular protection plate 301 is sleeved on the outside of the annular support sleeve 310 and is connected to the annular support sleeve 310. 0 rotational cooperation, a connecting rod 307 is provided above the rotating shaft 110, and a fixing sleeve 309 is provided at the bottom of the connecting rod 307. The fixing sleeve 309 is covered on the top of the rotating shaft 110. The inner side of the fixing sleeve 309 is rotatably connected to the inner sleeve 308. The inner sleeve 308 is sleeved on the outer side of the rotating shaft 110. The inner sleeve 308 and the fixing sleeve 309 are rotationally cooperated. The support sleeve 304 located on the upper end surface of the annular guard plate 301 is rotatably sleeved on the upper part of the connecting rod 307. A second support rod 113 is provided between the connecting rod 307 and the cantilever 101. Since the fixing sleeve 309 at the bottom of the connecting rod 307 is rotatably connected to the rotating shaft 110, the annular guard plate 301 will not be driven to rotate during the rotation of the propeller 102, so that the annular guard plate 301 and the rotating shaft 110 can rotate independently.

[0028] During the flight of a drone, most collisions occur when an external object rubs against the side of the drone. At this time, the annular protective plate 301 collides with the external object and rotates, converting and absorbing a certain amount of collision energy, thereby reducing the impact of the collision on the drone body 100.

[0029] A protective net 306 is provided between the annular protective plate 301 and the support sleeves 304 on the upper and lower sides, respectively, for protecting the propeller 102 from above and below, and preventing foreign objects from directly hitting the propeller 102 from above or below.

[0030] A buffer pad 303 is provided on the outside of the annular protective plate 301. The buffer pad 303 is evenly distributed along the circumference of the annular protective plate 301. The buffer pad 303 and the ventilation holes 302 are alternately arranged. When a collision occurs, the buffer pad 303 can be deformed to absorb part of the impact, further improving the protective performance of the protective mechanism 300.

[0031] Reference Figure 5-Figure 8A transparent cover 400 is provided at the bottom of the drone body 100 outside the surveying and mapping camera 200. The transparent cover 400 is used to protect the surveying and mapping camera 200 and reduce the risk of collision damage to the surveying and mapping camera 200. The transparent cover 400 is detachably connected to the surveying and mapping camera 200.

[0032] Specifically, the transparent cover shell 400 includes a mask portion 401 and a connecting portion. The mask portion 401 adopts a box-type structure. One side of the mask portion 401 is open. The side panel adjacent to the opening is a movable panel 403. The movable panel 403 is slidably connected to the side panels on both sides. The connecting portion includes connecting plates 402 arranged on both sides of the opening. The connecting plates 402 on both sides are aligned and parallel. A first threaded hole 407 is provided at one end of the connecting plate 402. Positioning plates 404 are correspondingly provided on both sides of the movable plate 403. The positioning plates 404 are provided with a second threaded hole 406 aligned with the first threaded hole 407. The aligned first threaded hole 407 and the second threaded hole 406 are connected by a screw 405 to connect and fix the movable plate 403 to the connecting plates 402 on both sides.

[0033] An L-shaped plate 105 is provided on both sides of the surveying camera 200 at the bottom of the drone body 100. A strip groove 106 is provided on the drone body 100 aligned with the L-shaped plate 105. A spring 107 is provided in the strip groove 106. A splint 108 is provided at one end of the spring 107 close to the L-shaped plate 105. A recess 112 is provided at one end of the drone body 100 close to the strip groove 106. The recess 112 is used for the end of the screw 405 to pass through. Correspondingly, a protrusion 104 is provided between the other ends of the strip grooves 106 on both sides. The protrusion 104 is used to cooperate with the recess 112 to position the transparent cover 400.

[0034] In order to facilitate the transparent cover 400 to penetrate the gap between the splint 108 and the L-shaped plate 105, a first wedge-shaped portion 408 is provided at the penetration end of the connecting plate 402, and a second wedge-shaped portion 111 is correspondingly provided on one side of the splint 108. The second wedge-shaped portion (111) is located at one end of the splint (108) close to the protrusion (104). When the connecting plate 402 penetrates the gap between the L-shaped plate 105 and the splint 108, the first wedge-shaped portion 408 and the second wedge-shaped portion 111 slide relative to each other, so that the connecting plate 402 squeezes the splint 108 and penetrates the gap between the splint 108 and the L-shaped plate 105.

[0035] When installing the transparent cover 400, the movable plate 403 is separated from the connecting plate 402, and the opening on one side of the movable plate 403 is directed toward the surveying camera 200. The connecting plates 402 on both sides are aligned and penetrate into the gap between the L-shaped plate 105 and the clamping plate 108. At the same time, the connecting plate 402 squeezes the spring 107 through the clamping plate 108, and the end of the connecting plate 402 passes through the L-shaped plate 105. At this time, the first threaded hole 407 is aligned with the recessed portion 112, and the protrusion 104 abuts against the side plate of the transparent cover 400. The movable plate 403 is slid so that the positioning plates 404 set on both sides of the movable plate 403 abut against the connecting plates 402 on both sides respectively, and the second threaded hole 407 is aligned with the recessed portion 112. 06 is aligned with the first threaded hole 407, and the screw 405 is screwed in. The screw 405 passes through the second threaded hole 406 and the first threaded hole 407 in sequence, and the end of the screw 405 passes through the recessed portion 112. The recessed portion 112 and the protrusion 104 cooperate to limit the transparent cover shell 400 to prevent the transparent cover shell 400 from being separated from the L-shaped plate 105 due to shaking during flight. At the same time, the spring 107 drives the splint 108 and the L-shaped plate 105 to clamp the connecting plate 402, further fixing the transparent cover shell 400 and ensuring the stability of the connection between the transparent cover shell 400 and the drone body 100. This structure is simple and practical, and is convenient for quick loading and unloading of the transparent cover shell 400.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
