Description

Technical Field

[0001] This utility model relates to the field of aerial photography drone technology, and more specifically to an aerial photography drone for slope inspection in water conservancy projects. Background Technology

[0002] Water conservancy engineering slopes are slopes that have been artificially modified or affected by engineering activities during the construction of water conservancy and hydropower projects. They are mainly protected by excavation and support techniques to ensure the stability of the foundations of water conservancy facilities such as hydropower stations and dams, and to prevent geological disasters such as landslides and collapses. In order to ensure construction safety, prevent geological disasters, and protect the ecological environment, it is necessary to regularly inspect the slopes to ensure their safety. However, the slopes are large and sloping, making manual inspection inconvenient. Aerial drones are an important inspection equipment. Aerial drones mainly acquire high-definition images from an aerial perspective and transmit the captured images to a monitoring terminal in real time via wireless network for data analysis, thereby realizing remote inspection of slopes.

[0003] Current technology has shortcomings: Slopes in water conservancy projects are often located near water bodies, resulting in high humidity levels as water evaporates into the air. During aerial inspections by drones, this humidity easily condenses on the camera, affecting the clarity of the captured images and the effectiveness of the inspection. Furthermore, debris can easily adhere to the camera, obstructing the view. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides an aerial photography drone based on slope inspection of water conservancy projects, so as to solve the problems existing in the background art.

During the flight inspection of the UAV body 1, the first drive motor 206 drives the drive gear 207 to rotate. Through the meshing of the drive gear 207 and the first transmission gear 205, the transparent protective cover 201 rotates at high speed along the annular groove 101. Under the action of centrifugal force, water vapor and debris on the surface of the transparent protective cover 201 splash around, keeping the surface of the transparent protective cover 201 clean. The camera mechanism 3 takes pictures and inspects the surroundings through the transparent protective cover 201.

[0017] The bottom of the drone body 1 is fixedly connected to a shell 203 corresponding to the position of the transparent protective cover 201. A mounting post 202 is movably sleeved on the side of the shell 203. A scraper 204 is fixedly connected to the side of the mounting post 202. The inner wall of the scraper 204 is movably connected to the side of the transparent protective cover 201. During equipment inspection, every once in a while, the mounting post 202 drives the transparent protective cover 201 to rotate so that the scraper 204 remains vertical and the inner wall of the scraper 204 is in close contact with the side of the transparent protective cover 201 to remove stubborn stains. Then the mounting post 202 drives the scraper 204 to rotate upward so that the scraper 204 is in close contact with the bottom of the drone body 1 to avoid obstructing the transparent protective cover 201.

[0018] The main body 1 of the UAV is internally fixedly connected to an adjustment mechanism 208. The output shaft of the adjustment mechanism 208 is fixedly connected to a second drive motor 209. A second transmission gear 210 is fixedly sleeved on the side of the mounting column 202. The top end of the second transmission gear 210 meshes with the bottom end of the second drive motor 209. The adjustment mechanism 208 drives the second drive motor 209 to rotate. The meshing of the second drive motor 209 and the second transmission gear 210 drives the mounting column 202 to rotate.

[0019] The camera mechanism 3 includes a mounting shaft 306, the top of which is movably connected to the bottom of the drone body 1. A mounting bracket 304 is fixedly connected to the bottom of the mounting shaft 306, and a mounting rod 309 is movably connected to the bottom of the mounting bracket 304. The camera body 301 is fixedly connected to the side of the mounting rod 309.

[0020] The drone body 1 is fixedly connected to the bottom of a first servo motor 305. The output shaft of the first servo motor 305 is fixedly connected to a first worm gear 302. A first worm wheel 303 is fixedly sleeved on the side of the mounting shaft 306. The side of the first worm wheel 303 meshes with the side of the first worm gear 302. The first servo motor 305 drives the first worm gear 302 to rotate. Through the meshing of the first worm gear 302 and the first worm wheel 303, the mounting shaft 306 drives the mounting frame 304 to rotate in the horizontal plane, so that the camera body 301 rotates to take pictures of the surroundings.

[0021] The mounting bracket 304 has a second servo motor 307 fixedly connected to its bottom end. The output shaft of the second servo motor 307 is fixedly connected to a second worm gear 308. A second worm wheel 310 is fixedly sleeved on the side of the mounting rod 309. The top end of the second worm wheel 310 meshes with the bottom end of the second worm gear 308. The second servo motor 307 drives the second worm gear 308 to rotate. Through the meshing of the second worm gear 308 and the second worm wheel 310, the mounting rod 309 rotates in the vertical plane, causing the camera body 301 to rotate up and down for shooting.

[0022] The working principle of this utility model is as follows: During flight, the main body of the drone 1 is driven by the first servo motor 305 to rotate the first worm gear 302 according to the usage requirements. The first worm gear 302 meshes with the first worm wheel 303, causing the mounting shaft 306 to rotate the mounting bracket 304 in the horizontal plane, thus rotating the camera body 301 to capture images from all directions. The second servo motor 307 drives the second worm gear 308 to rotate. The second worm gear 308 meshes with the second worm wheel 310, causing the mounting rod 309 to rotate in the vertical plane, thus rotating the camera body 301 up and down to capture images from all directions below the drone body 1. During the flight inspection process of the drone body 1, the first drive motor 206 drives the drive gear 207 to rotate, which in turn rotates the mounting rod 309 in the vertical plane, causing the camera body 301 to rotate up and down to capture images from all directions below the drone body 1. During the flight inspection process, the first drive motor 206 drives the drive gear 207 to rotate, thus rotating the mounting rod 309 in the vertical plane, thus rotating the camera body 301 to capture images from all directions below the drone body 1. A transmission gear 205 meshes with each other, driving the transparent protective cover 201 to rotate at high speed along the annular groove 101. Under the action of centrifugal force, water vapor and debris on the surface of the transparent protective cover 201 splash in all directions, keeping the surface of the transparent protective cover 201 clean. Every once in a while, the adjustment mechanism 208 is activated to drive the second drive motor 209 to rotate. The second drive motor 209 meshes with the second transmission gear 210 to drive the mounting column 202 to rotate, driving the transparent protective cover 201 to rotate and keep the scraper 204 vertical. This ensures that the inner wall of the scraper 204 is in close contact with the side of the transparent protective cover 201, removing stubborn stains. Then, the adjustment mechanism 208 is activated in the opposite direction to rotate the scraper 204 upward, so that the scraper 204 is in close contact with the bottom of the drone body 1, avoiding obstruction of the transparent protective cover 201.
