[0015] A method for using an auxiliary tool for aerial photogrammetry comprises the following steps:

[0016] Step 1: Take a video, start the aerial camera, the aerial camera drives the platform to fly at high altitude, the platform drives the fixed plate to fly, the fixed plate drives the round rod to fly, the round rod drives the piston plate to fly, the piston plate drives the first spring to fly, the first spring drives the sliding frame to fly, the sliding frame drives the bearing shell to fly, the bearing shell drives the slider to fly, the slider drives the square ring to fly, and the square ring drives the camera to fly;

[0017] Step 2: Reduce the impact force. When the sliding frame and the piston plate are approaching each other inside the square shell, the air pressure inside the square shell enters the elastic tube, and the airflow enters the bearing bag through the elastic tube, causing the bearing bag to expand. During the expansion of the bearing bag, the square ring can be supported to prevent the camera from causing impact when driving the square ring to descend rapidly.

[0018] Step three: Improve the working stability of the camera. When the force of the aerial camera to descend vertically is too large, the reaction force generated causes the camera to move upward. The camera drives the bearing shell in the support assembly to move upward, and the bearing shell drives the first rotating bar to move upward. Due to the setting of the sliding hole, the first rotating bar drives the sliding bar to slide along the inner wall of the sliding hole, and the two sliding bars approach each other. The sliding bar drives the second rotating bar to move. Because one end of the limit rod slides on the top of the support frame, the second rotating bar can drive the square plate to move vertically downward. The square plate drives the vertical rod to descend, the vertical rod drives the limit rod to descend, the limit rod drives the shock-absorbing shell to descend, the shock-absorbing shell drives the lifting plate to descend, the lifting plate drives the round sleeve rod to descend, and the round sleeve rod drives the flexible box to descend. The flexible box will come into contact with the rising camera during the descent process.

[0019] Step 4: Auxiliary protection effect. When the flexible box contacts the camera, the reaction force of the camera causes the flexible box to drive the round sleeve rod to approach the shock-absorbing shell. The round sleeve rod drives the lifting plate to slide inside the shock-absorbing shell. The reset spring prevents the lifting plate from colliding with the top of the inner wall of the shock-absorbing shell when it rises, thereby reducing the impact force generated when the camera rises.

[0020] The present invention has the following beneficial effects:

[0021] (1) The present invention starts the aerial camera, the aerial camera drives the platform to fly at high altitude, the platform drives the fixed plate to fly, the fixed plate drives the round rod to fly, the round rod drives the piston plate to fly, the piston plate drives the first spring to fly, the first spring drives the sliding frame to fly, the sliding frame drives the bearing shell to fly, the bearing shell drives the slider to fly, the slider drives the square ring to fly, the square ring drives the camera to fly, so that the camera can be taken during the flight. When the vertical upward force of the aerial camera is too large, the reaction force generated causes the camera to move downward, and the camera drives the bearing in the support assembly The shell moves downward, and the load-bearing shell drives the sliding frame to move downward. Under the setting of the first spring, the sliding frame approaches the piston plate inside the square shell and is affected by the air pressure inside the square shell, thereby preventing the camera from falling too sharply and causing impact, thereby improving the protection effect of the camera. At the same time, the sliding frame and the fixed plate approach each other, and the sliding frame drives the second rotating plate and the fixed plate drives the first rotating plate to move closer to each other. Under the setting of the fixed groove plate, the second rotating plate and the first rotating plate drive the sliding part to slide along the inner wall of the fixed groove plate, thereby further reducing the impact force generated when the camera descends, thereby improving the protection effect of the camera.

[0022] (2) According to the present invention, when the sliding frame and the piston plate approach each other inside the square shell, the air pressure inside the square shell enters into the elastic tube, and the airflow enters into the carrying bag through the elastic tube, causing the carrying bag to expand. During the expansion of the carrying bag, the square ring can be supported to prevent the camera from causing impact force when the square ring is driven to descend rapidly, thereby improving the protection effect of the camera. When the carrying bag expands, the square ring drives the camera to rise slightly, and the square ring drives the slider to rise slightly. The slider is elastically deformed by the second spring, and the second spring slightly squeezes the slider to prevent the slider from colliding with the top of the inner wall of the slide groove, thereby further reducing the impact on the camera when it descends, thereby improving the protection effect of the camera.

[0023] (3) According to the present invention, when the force of the aerial camera to descend vertically is too large, the reaction force generated causes the camera to move upward, and the camera drives the bearing shell in the support assembly to move upward, and the bearing shell drives the first rotating bar to move upward. Due to the setting of the sliding hole, the first rotating bar drives the sliding bar to slide along the inner wall of the sliding hole, and the two sliding bars approach each other, and the sliding bar drives the second rotating bar to move. Because one end of the limit rod slides on the top of the support frame, the second rotating bar can drive the square plate to move vertically downward, the square plate drives the vertical rod to descend, the vertical rod drives the limit rod to descend, the limit rod drives the shock-absorbing shell to descend, the shock-absorbing shell drives the lifting plate to descend, the lifting plate drives the round sleeve rod to descend, and the round sleeve rod drives the flexible box to descend. During the descent of the flexible box, it will come into contact with the rising camera, so as to prevent the camera from rising too far and causing the camera to fall off, thereby improving the stability of the camera operation.

[0024] (4) According to the present invention, when the flexible box contacts the camera, it is subjected to the reaction force of the camera, so that the flexible box drives the round sleeve rod to approach the shock-absorbing shell, and the round sleeve rod drives the lifting plate to slide inside the shock-absorbing shell. The reset spring is set to prevent the lifting plate from colliding with the top of the inner wall of the shock-absorbing shell when it rises, thereby reducing the impact force generated when the camera rises and improving the protective effect of the camera. When the lifting plate slides inside the shock-absorbing shell, the airflow inside the shock-absorbing shell enters the interior of the vertical pipe, the airflow enters the interior of the flexible box through the vertical pipe, the airflow enters the interior of the circular tube through the flexible box, the airflow enters the interior of the jet shell through the circular tube, and the airflow passes through the jet shell to spray toward the mirror surface of the camera, thereby preventing dust from adhering to the mirror surface of the camera when the camera is flying, thereby improving the camera's shooting accuracy.

[0025] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] A method for using an auxiliary tool for aerial photogrammetry comprises the following steps:

[0052] Step 1: Take a video, start the aerial camera, the aerial camera drives the platform 1 to fly at high altitude, the platform 1 drives the fixed plate 41 to fly, the fixed plate 41 drives the round rod 42 to fly, the round rod 42 drives the piston plate 43 to fly, the piston plate 43 drives the first spring 451 to fly, the first spring 451 drives the sliding frame 452 to fly, the sliding frame 452 drives the bearing shell 453 to fly, the bearing shell 453 drives the slider 456 to fly, the slider 456 drives the square ring 457 to fly, and the square ring 457 drives the camera 2 to fly;

[0053] Step 2: Reduce the impact force. When the sliding frame 452 and the piston plate 43 are approaching each other inside the square shell 44, the air pressure inside the square shell 44 enters the elastic tube 466, and the airflow enters the inside of the carrying bag 458 through the elastic tube 466, so that the carrying bag 458 expands. During the expansion of the carrying bag 458, the square ring 457 can be supported to prevent the camera 2 from causing an impact force when driving the square ring 457 to drop rapidly.

[0054] Step 3: Improve the working stability of the camera 2. When the vertical descent force of the aerial camera is too large, the reaction force generated causes the camera 2 to move upward. The camera 2 drives the bearing shell 453 in the support assembly 45 to move upward. The bearing shell 453 drives the first rotating bar 471 to move upward. Due to the setting of the sliding hole 473, the first rotating bar 471 drives the sliding bar 472 to slide along the inner wall of the sliding hole 473. The two sliding bars 472 move closer to each other, and the sliding bar 472 drives the second rotating bar 474 to move. Because the limit rod One end of 478 slides on the top of the support frame 3, so the second rotating bar 474 can drive the square plate 475 to perform vertical downward movement, the square plate 475 drives the vertical rod 477 to descend, the vertical rod 477 drives the limit rod 478 to descend, the limit rod 478 drives the shock absorbing shell 479 to descend, the shock absorbing shell 479 drives the lifting plate 4710 to descend, the lifting plate 4710 drives the round sleeve rod 4711 to descend, the round sleeve rod 4711 drives the flexible box 4712 to descend, and the flexible box 4712 will come into contact with the rising camera 2 during the descending process;

[0055] Step 4: Auxiliary protection effect. When the flexible box 4712 contacts the camera 2, it is subjected to the reaction force of the camera 2, so that the flexible box 4712 drives the round sleeve rod 4711 to approach the shock-absorbing shell 479. The round sleeve rod 4711 drives the lifting plate 4710 to slide inside the shock-absorbing shell 479. The reset spring 481 is set to prevent the lifting plate 4710 from colliding with the top of the inner wall of the shock-absorbing shell 479 when rising, thereby reducing the impact force generated when the camera 2 rises.

[0056] When in use, the aerial camera is started, and the aerial camera drives the platform 1 to fly at high altitude, the platform 1 drives the fixing plate 41 to fly, the fixing plate 41 drives the round rod 42 to fly, the round rod 42 drives the piston plate 43 to fly, the piston plate 43 drives the first spring 451 to fly, the first spring 451 drives the sliding frame 452 to fly, the sliding frame 452 drives the bearing shell 453 to fly, the bearing shell 453 drives the slider 456 to fly, the slider 456 drives the square ring 457 to fly, and the square ring 457 drives the camera 2 to fly, so as to perform camera work during the flight. When the vertical upward force of the aerial camera is too large, the reaction force generated causes the camera 2 to move downward, and the camera 2 drives the bearing shell 453 in the support assembly 45 to The downward movement, the bearing shell 453 drives the sliding frame 452 to move downward, and under the setting of the first spring 451, the sliding frame 452 and the piston plate 43 are moved closer to each other inside the square shell 44, and under the setting of the air pressure inside the square shell 44, the camera 2 is prevented from falling too sharply and causing impact, thereby improving the protection effect of the camera 2. At the same time, the sliding frame 452 and the fixed plate 41 move closer to each other, and the sliding frame 452 drives the second rotating plate 465 and the fixed plate 41 to drive the first rotating plate 464 to move closer to each other. Under the setting of the fixed groove plate 462, the second rotating plate 465 and the first rotating plate 464 drive the sliding member 463 to slide along the inner wall of the fixed groove plate 462, thereby further reducing the impact force generated when the camera 2 descends, thereby improving the protection effect of the camera 2.

[0057] When the sliding frame 452 and the piston plate 43 are approaching each other inside the square shell 44, the air pressure inside the square shell 44 enters into the elastic tube 466, and the airflow enters into the carrying bag 458 through the elastic tube 466, causing the carrying bag 458 to expand. During the expansion of the carrying bag 458, the square ring 457 can be supported to prevent the camera 2 from causing an impact force when the square ring 457 is driven to descend rapidly, thereby improving the protection effect of the camera 2. When the carrying bag 458 expands, the square ring 457 drives the camera 2 to rise slightly, and the square ring 457 drives the slider 456 to rise slightly, which is elastically deformed by the second spring 455. The second spring 455 slightly squeezes the slider 456 to prevent the slider 456 from colliding with the top of the inner wall of the slide groove 454, further reducing the impact on the camera 2 when it descends, thereby improving the protection effect of the camera 2.

[0058] When the force of the aerial camera to descend vertically is too large, the reaction force generated causes the camera 2 to move upward, and the camera 2 drives the bearing shell 453 in the support assembly 45 to move upward, and the bearing shell 453 drives the first rotating bar 471 to move upward. Due to the setting of the sliding hole 473, the first rotating bar 471 drives the sliding bar 472 to slide along the inner wall of the sliding hole 473, and the two sliding bars 472 approach each other. The sliding bar 472 drives the second rotating bar 474 to move. Because one end of the limit rod 478 slides on the top of the support frame 3, the second rotating bar 474 can The square plate 475 can be driven to move vertically downward, the square plate 475 drives the vertical rod 477 to descend, the vertical rod 477 drives the limit rod 478 to descend, the limit rod 478 drives the shock absorbing shell 479 to descend, the shock absorbing shell 479 drives the lifting plate 4710 to descend, the lifting plate 4710 drives the round sleeve rod 4711 to descend, the round sleeve rod 4711 drives the flexible box 4712 to descend, and the flexible box 4712 will come into contact with the rising camera 2 during the descending process, so as to prevent the camera 2 from rising too far and causing the camera 2 to fall off, thereby improving the working stability of the camera 2.

[0059] When the flexible box 4712 contacts the camera 2, the reaction force of the camera 2 causes the flexible box 4712 to drive the round sleeve rod 4711 to approach the shock absorbing shell 479, and the round sleeve rod 4711 drives the lifting plate 4710 to slide inside the shock absorbing shell 479. The reset spring 481 is set to prevent the lifting plate 4710 from colliding with the top of the inner wall of the shock absorbing shell 479 when it rises, thereby reducing the impact force generated when the camera 2 rises, improving the protection effect of the camera 2, and the lifting plate 4710 When sliding inside the shock-absorbing shell 479, the airflow inside the shock-absorbing shell 479 enters into the interior of the vertical pipe 482, the airflow enters into the interior of the flexible box 4712 through the vertical pipe 482, the airflow enters into the interior of the circular tube 485 through the flexible box 4712, the airflow enters into the interior of the jet shell 484 through the circular tube 485, and the airflow is sprayed toward the mirror surface of the camera 2 through the jet shell 484, so as to prevent dust from adhering to the mirror surface of the camera 2 when the camera 2 is flying, thereby improving the shooting accuracy of the camera 2.
